When WebKit alternates between two measured window-metric sets (A -> B -> A -> B) after getBoundingClientRect(), each key transition renewed the two-render budget and the requestAnimationFrame/geometry-measurement loop never terminated (WebContent ~30% CPU for minutes after session recovery). The MESSAGE_VIRTUAL_MEASUREMENT_MAX_RERENDERS budget now caps the whole convergence burst globally; the cycle-key branch only records the new key. The budget still resets at the correct lifecycle boundaries: _markMessageVirtualMeasurementsSettled() and _clearMessageVirtualHeightCache().

The backend then labeled the continuation as relationship_type=child_session, causing duplicate same-title sidebar rows and spurious child-session entries (#6931). Allow a small tolerance (2s) for handoff-consistent timing; beyond it, an exact title match on the parent/child rows still confirms the same handoff. Fork, cross-source, and non-compression/cli_close guards are preserved, and materially overlapping children remain separate child sessions. Adds API-level regression tests (sub-second overlap forms one lineage; material overlap stays a child session; same-title evidence beyond tolerance) plus focused unit coverage of the classifier.

MUST-FIX 1 — branch marker in model_config. The session_source=='fork' guard only covers WebUI-created forks (/api/session/branch). Explicit Agent branches/delegates carry no session_source: they are marked in the model_config JSON column (_branched_from / _delegate_from). The caller queries did not select model_config at all, so an Agent branch starting inside the 2s tolerance window of its parent's compression passed the widened check and vanished from the sidebar. Fix: select model_config in the classifier's caller queries (get_cli_sessions, lineage report, lineage metadata) and reject a child whose _branched_from / _delegate_from points at the parent being classified, BEFORE the tolerance is applied. The marker must reference this parent: compression continuations inherit the rotated agent's model_config verbatim (mirrors hermes-agent _NON_CONTINUATION_CHILD_FILTER_SQL). 2. MUST-FIX 2 — unbounded title fallback removed. Titles are user-controlled and non-unique, so parent_title == child_title beyond the tolerance window collapsed independent same-title branches arbitrarily far apart. The fallback is gone entirely; only the bounded 2s early-side tolerance (CONTINUATION_STARTED_AT_TOLERANCE_SECONDS) remains, after the reliable non-continuation guards. Tests: same-title independent child outside tolerance stays visible (was collapsed); _branched_from/_delegate_from children inside the tolerance stay visible (reviewer's adversarial probe); unit coverage for marker parsing (JSON string, dict, unparsable) and marker-points-at-other-session preservation.

Keep scanning until the first complete user+assistant pair instead, and fall back to the last complete exchange when the opening user message yields no user text (privacy scrubbing) instead of failing with empty_user_message. Tests: tests/test_issue7543_title_first_exchange.py (8 cases, incl. the issue-pinned transcript shape and walker-mocked discriminator tests for both fixes). * test(api): drop local-machine notes and sys.path hack from 7543 test module - Docstring described the change as a local-only uncommitted hotfix with machine-specific paths — wrong for an upstream PR and unsafe to publish. - Drop the defensive REPO_ROOT sys.path insert; the repo conftest already puts the package root on sys.path (matches the neighboring test modules). * fix(api): drop unreachable latest-exchange fallback from title regeneration Greptile flagged the mocked-walker fallback test (P2) as fabricating internal state, and an exhaustive enumeration of realistic transcript shapes (5460 combinations, lengths 1-6) confirms it: both walkers share the same text extraction and the forward walker scans every message, so 'first walker empty while latest walker yields a pair' is unreachable from real transcripts. The fallback branch was dead code. Remove it together with its two walker-mocked tests; the fixed first- exchange walker alone resolves the reported issue shape. Replace the mocked tests with an observable E2E error-path test through the real walkers, and make the aux mock guard-faithful (empty assistant_text -> missing_exchange per the generate_title_raw_via_aux contract) so the fail-before proof actually exercises the endpoint contract. * fix(#7543): scope first-exchange scan-past to the manual-regen path only The full suite caught that broadening the SHARED _first_exchange_snippets also activated the automatic in-stream background-title path for consecutive-user-row transcripts, moving stream teardown from the synchronous stream_end branch to the background-title-thread branch (test_issue3929 emits_done regressed: stream_end was no longer in the synchronous queue). #7543 is specifically about the MANUAL 'Regenerate title' endpoint, so gate the scan-past behavior behind an opt-in scan_past_consecutive_users flag (default False = master behavior) and pass True only from generate_session_title_for_session. Auto in-stream path is now byte-identical to master; added a default-behavior regression guard test. * docs(changelog): stamp #7545 (manual title regen for queued-user transcripts) --------- Co-authored-by: Raylands Co-authored-by: nesquena-hermes Co-authored-by: n --- CHANGELOG.md | 2 + api/streaming.py | 28 +++- tests/test_issue7543_title_first_exchange.py | 165 +++++++++++++++++++ 3 files changed, 190 insertions(+), 5 deletions(-) create mode 100644 tests/test_issue7543_title_first_exchange.py diff --git a/CHANGELOG.md b/CHANGELOG.md index c7ecc5de..f3ba6229 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -5,6 +5,8 @@ ### Fixed +- **Manual "Regenerate title" now works for conversations that open with several queued user messages.** For a session whose transcript begins with consecutive user turns (no assistant reply before the second user message), the first-exchange walker stopped at the second user row with no assistant text, so "Regenerate title" skipped the LLM call, silently persisted the local fallback (a truncated first message), and returned `200` with that same wrong title on every retry — leaving the session permanently stuck.

Every Codex refresh therefore invalidated the cache, and the next session open paid a full live rebuild whose serial provider probes stalled the open (#7540). The Codex cache is now fingerprinted by its *content* with the refresh-timestamp fields (`fetched_at`, `updated_at`) stripped, so a timestamp-only rewrite keeps the cache while any genuine catalog change (models, `etag`, `client_version`) still invalidates it. A malformed or pathologically deep cache file degrades safely to the old stat fingerprint rather than erroring. Thanks @webtecnica. (#7556, closes #7540) + - **A timed-out command-approval card can be dismissed again instead of getting stuck on screen forever.** When the agent raised a local approval with no gateway notifier registered, the raw pending entry was stored without an `approval_id`; the frontend needs that id to own the card, so a card that timed out (or otherwise went unanswered) could be neither approved nor dismissed and the poll re-served it indefinitely. Reconciliation now mints a stable `gwlocal-mirrorless:` id on the raw local entry itself — the same tokenization contract already used for gateway producers — so the id survives repeated polls and the client's dismiss marker sticks. Gateway/run-bearing entries are untouched, and the synthetic prefix can't be mistaken for gateway authority (routing keys on exact ids, `run_id`, and mirror tokens, never the prefix). Thanks @CharlesMcquade. (#7510) - **Manual "Regenerate title" now works for conversations that open with several queued user messages.** For a session whose transcript begins with consecutive user turns (no assistant reply before the second user message), the first-exchange walker stopped at the second user row with no assistant text, so "Regenerate title" skipped the LLM call, silently persisted the local fallback (a truncated first message), and returned `200` with that same wrong title on every retry — leaving the session permanently stuck. Manual regeneration now scans past the opening user rows to the first complete user+assistant pair so it reaches the aux model. The automatic in-stream title path is deliberately unchanged.

Plain delimiter concatenation let approval_id='x\0r\0t' (no gateway owner) collide with approval_id='x' + run 'r' + token 't'; the gateway accepts approval_id as an unrestricted string, so the second distinct owner was suppressed. - Seen entries retire on prompt LIFECYCLE via the pending-clear chokepoints (_clearApprovalPendingForSession/_clearClarifyPendingForSession now call _retirePromptNotifyKey) instead of a 10-minute wall-clock TTL, so a prompt left pending for hours never re-notifies while a resolved prompt whose ID is reused legitimately notifies again. - Entries are no longer recorded when notifications are disabled, so enabling mid-prompt re-notifies that owner instead of the disabled call permanently consuming it. New regressions: key injectivity with delimiter-bearing approval_id, 24h-still-pending no-renotify, resolved-owner ID reuse, and disabled-to-enabled retry.

Cleanup only removed the key of the currently stored prompt, and since dedupe entries no longer expire on a wall-clock TTL, a stale key persisted forever - so the same externally supplied prompt ID re-surfacing later was wrongly suppressed as already-notified. _rememberApprovalPending() and _rememberClarifyPending() now retire the displaced entry's notify key on owner change. A re-render of the SAME owner serializes to the same typed tuple key, so repeated poll ticks stay deduped.

With no storage listener for either key, a stale client overwrites the other's writes: a session's viewed count can roll backwards (re-lighting a cleared unread dot via message_count > viewed_count) and a cleared completion-unread marker can be resurrected. Fix the class: - max-merge viewed counts on save so a count is monotonic and additive across clients, never dropping another client's entries or lowering a value; - keep the in-cache viewed count monotonic on set; - delete a viewed count directly from the persisted map (removals must still leave disk, unlike the additive set path); - invalidate both unread caches on storage events so a concurrent write is re-read instead of overwritten.

Max-merging viewed counts on save and dropping the caches on a storage event was not enough: a save read the store, merged its cache and wrote the result back, so a write landing inside another client's read-modify-write window was still lost — and the surviving client only forgot its own cache, so it re-read the value that had already been lost. A viewed count could roll backwards and re-light a cleared dot. The completion markers behind the visible dot were worse: that save was a wholesale overwrite with no merge at all, so a stale client re-serialising its cache re-added a marker another client had cleared. Make both stores converge on the later fact rather than on the last writer: - viewed counts mean "seen at least up to N messages", so they merge with a max: monotonic per session and additive across clients. A value that exists only in our cache is written back only for a session the session list still shows (_allSessions / _sessionListSnapshotById), so a session deleted in another client, already pruned from the store by _clearSessionViewedCount, is not resurrected. - completion markers are add/remove and cannot be ordered by a max, so every clear records a tombstone (hermes-session-completion-unread-cleared, sid -> clearedAt) and a marker that does not postdate its clear loses. A genuine later completion still wins. The tombstone store never enters the marker map that consumers read, and is pruned by session existence and by a 7-day cap. Both clear paths record it: _clearSessionCompletionUnread (visit / delete) and _clearCronSessionCompletionUnreadForInactiveProfiles (profile switch). - both saves write only when the store does not already hold the merged result, and the storage listener runs that same merge instead of dropping our cache. A client that still holds an acknowledgement therefore re-asserts it after the other client's write, the loser sees a value it cannot beat and stops, and a repair converges instead of ping-ponging storage events. tests/test_unread_cross_client_sync.py drives the real functions against a two-client harness sharing one fake localStorage: an interleaved write inside a read-modify-write window, a deleted session's count, a stale client's marker write after a clear, tombstone ordering vs a later re-mark, tombstone pruning, and the registered storage listener dispatched with synthetic events. tests/_unread_store_helpers.py gives the neighbouring node harnesses the helpers those persistence paths call, so they keep driving the real code. --- static/sessions.js | 226 +++++++- tests/_unread_store_helpers.py | 77 +++ .../test_issue5273_active_done_viewed_sync.py | 8 + ...est_issue5960_cron_unread_profile_scope.py | 20 + tests/test_session_unread_dot_on_visit.py | 9 + tests/test_unread_cross_client_sync.py | 503 +++++++++++++++--- 6 files changed, 729 insertions(+), 114 deletions(-) create mode 100644 tests/_unread_store_helpers.py diff --git a/static/sessions.js b/static/sessions.js index b0289aba..4915ebfb 100644 --- a/static/sessions.js +++ b/static/sessions.js @@ -347,6 +347,11 @@ function _clearComposerDraft(sid, text, files) { const SESSION_VIEWED_COUNTS_KEY = 'hermes-session-viewed-counts'; const SESSION_COMPLETION_UNREAD_KEY = 'hermes-session-completion-unread'; +// Cleared completion-unread markers leave a tombstone (sid -> clearedAt epoch ms) +// so a stale client that still holds the marker cannot resurrect it.

A viewed count another client acknowledged after our cache was loaded therefore survived session deletion, leaving one entry behind per deleted session — the quota pressure this prune path exists to avoid — and a later repair merged that stale entry back into the store. Read the store on every deletion and drop the key when the store holds it. The deletion must not cost this client the acknowledgement it holds for another session, so adopt the store's entries while keeping any higher count already cached — the merge the repair path uses — instead of replacing the cache with the store map. The write stays conditional, so a deletion that changes nothing does not fire a storage event. Behavioural two-client coverage in tests/test_unread_cross_client_sync.py: `test_delete_prunes_a_viewed_count_only_the_store_holds` and `test_delete_keeps_the_higher_count_this_client_holds_for_others`.

From 927f1ca4f72190016d60c16b78b8a0995d2e1e08 Mon Sep 17 00:00:00 2001 From: Michael Snoyman Date: Tue, 15 Sep 2026 15:48:02 +0300 Subject: [PATCH 042/446] docs(rfc): document the client-side unread persistence contract The run state consistency contract is where sidebar metadata work routes, and its state-layer table already lists the sidebar layer, but nothing recorded the rules the two client-side unread stores actually follow: viewed counts converge by a max merge, completion markers are ordered by per-session tombstones with a bounded retention window, and the storage listener repairs the store instead of only dropping the local cache. Write those rules down where they belong, naming the three localStorage keys and the retention cap, and state the limitation explicitly: each save is a read-modify-write across separate localStorage operations with no lock between them, so the contract is convergence rather than atomicity, and two concurrent clears can still lose a tombstone. tests/test_webui_run_state_consistency_contract_rfc.py pins the documented keys and the documented retention window to the constants in static/sessions.js, so changing one without the other fails. It fails on the previous revision and passes with this change. --- .../webui-run-state-consistency-contract.md | 49 +++++++++++++- ...ebui_run_state_consistency_contract_rfc.py | 65 +++++++++++++++++++ 2 files changed, 113 insertions(+), 1 deletion(-) create mode 100644 tests/test_webui_run_state_consistency_contract_rfc.py diff --git a/docs/rfcs/webui-run-state-consistency-contract.md b/docs/rfcs/webui-run-state-consistency-contract.md index ca185de6..f7fd90b9 100644 --- a/docs/rfcs/webui-run-state-consistency-contract.md +++ b/docs/rfcs/webui-run-state-consistency-contract.md @@ -3,7 +3,7 @@ - **Status:** Proposed - **Author:** @franksong2702 - **Created:** 2026-05-16 -- **Updated:** 2026-08-22 +- **Updated:** 2026-09-15 - **Tracking issue:** [#2361](https://github.com/nesquena/hermes-webui/issues/2361) - **Related architecture:** [#1925](https://github.com/nesquena/hermes-webui/issues/1925), [`hermes-run-adapter-contract.md`](hermes-run-adapter-contract.md), [`stable-assistant-turn-anchors.md`](stable-assistant-turn-anchors.md) @@ -75,6 +75,7 @@ and 5; it does not mark every run-state boundary implemented. | Compression summary / handoff | Gives the agent recovery context after automatic compression | Must remain agent-facing recovery material unless explicitly rendered as history | Pollute the active turn or become implicit current user intent | | Live UI scene/cache | Preserves expanded rows, in-progress cards, local scroll, and transient grouping | May optimize presentation but must be rebuildable or degradable from transcript/replay | Become the only place where chronological ordering exists | | Sidebar/session metadata | Helps the user find active and recent sessions | Must reflect meaningful user or assistant activity | Treat background cleanup as a fresh user-facing update | +| Client-side unread stores (`localStorage`) | Backs the sidebar unread dot for every client on the origin | Converges across clients by merge and tombstone ordering; not atomic | Let one client's stale cache lower a count or resurrect a cleared marker | ## Core Invariants @@ -153,6 +154,48 @@ and 5; it does not mark every run-state boundary implemented. timestamp (falling back to run start), so a long-running turn cancelled moments ago is never mistaken for an orphan. +## Client-side unread persistence (sidebar layer) + +The sidebar unread dot is backed by two client-side stores in `static/sessions.js`. +Both live in `localStorage` under the origin, so every WebUI client on the same +origin/profile (a PWA window and a browser tab, for example) shares them while each +client also caches them in module state.

Clear records were pruned on session existence, which deleted the ordering fact for any session outside the current filter and re-lit a dot the user had cleared.

A client that still caches the acknowledgement now prunes it rather than writing it back. The previous clear representation is imported once and then removed.

Path Resolution Contract + +1. **Target-side POSIX Path Preservation:** + - Any valid POSIX path at or beneath a remote profile's configured `terminal.cwd` is preserved verbatim as a `Path` object without calling host-local `Path.resolve()`. + - Traversal escapes (`..`), null bytes (`\0`), and blocked system roots (`/etc`, `/usr`, `/var`, `/sys`, `/proc`, `/dev`) continue to be strictly rejected. + +2. **Profile Isolation & Boundary Enforcement:** + - Remote path recognition is **strictly scoped to the target/active profile**. + - If an active profile has a local backend, target-side remote paths belonging to inactive named profiles are **not** treated as remote for the active local profile. + - For local profiles, workspace addition (`/api/workspaces/add`) enforces host-local directory existence and permissions. + - For remote profiles, workspace addition validates against the profile's remote `terminal.cwd` and skips host-local directory creation (`mkdir`). + +3. **Session & Streaming Lifecycle:** + - `Session.__init__` and `Session.load` normalize session workspace paths through `_resolve_path(..., profile=profile)`, preserving target-side paths for remote profiles and preventing corruption of `session.workspace` or `session.created_workspace`. + - Streaming execution (`_run_agent_streaming`) and multimodal asset root resolution preserve the remote session workspace when updating runtime run state. diff --git a/tests/conftest.py b/tests/conftest.py index 7dc77884..a492e666 100644 --- a/tests/conftest.py +++ b/tests/conftest.py @@ -231,6 +231,44 @@ def _reset_password_hash_cache(): _invalidate_password_hash_cache() +def _strip_leaked_webui_password_env() -> None: + """Remove a leaked HERMES_WEBUI_PASSWORD between tests (#7168 review). + + bootstrap.py runs _load_repo_dotenv() at import time, which copies values + from the developer's real repo .env straight into os.environ.

uploads and project context.** When the terminal backend runs off-host, a workspace path such as `/srv/remote-alice` belongs to the *target* machine — but several resolvers normalized it against the WebUI host's filesystem, so a host-side expansion (macOS firmlinks turning it into `/System/Volumes/Data/srv/remote-alice`, or a local `~` expansion) could be persisted back onto the session and then

A delegated subagent is also technically cross-source relative to its WebUI parent, so it was swept up by that rule and surfaced as a bare top-level row with no indication of what spawned it. Delegated subagents are now exempt from that branch and attach to their visible parent, while independent cross-surface continuations still stay top level. The delegated role is resolved in strict precedence order from the first non-blank of `raw_source` → `source_tag` → `source` and additionally requires the backend's child-session flag, so a stale lower-priority field can't promote an independent row into a delegated one.

Measured behaviour is identical across both paths: 44px resting height, no jump when the first character is typed or the last deleted, growth to the 200px ceiling, then internal scrolling. Because `field-sizing` deliberately includes placeholder text in content sizing, `:placeholder-shown` pins fixed sizing while the composer is empty so a long placeholder can't inflate it. Thanks @starship-s. (#6760, #5514) + ### Fixed +- **An empty composer no longer inflates to fit its own placeholder on the JavaScript sizing path.** The fallback resizer measured `scrollHeight` for an empty textarea, which reflects the *placeholder* — so a long busy or compression hint (which wraps to two or three lines) grew the empty composer to roughly 71px, and only after a resize that happened while empty, making the resting height depend on history rather than content. The inline height is now cleared when the value is empty so CSS `min-height` defines the resting size, matching the native path. (#6760) + - **Delegated subagent sessions nest under the conversation that spawned them instead of landing at the top of the sidebar.** The sidebar forces a *cross-surface* child row to top level when its parent row belongs to another surface (a Telegram/messaging parent), so an independent continuation doesn't get stacked under a foreign thread. A delegated subagent is also technically cross-source relative to its WebUI parent, so it was swept up by that rule and surfaced as a bare top-level row with no indication of what spawned it. Delegated subagents are now exempt from that branch and attach to their visible parent, while independent cross-surface continuations still stay top level. The delegated role is resolved in strict precedence order from the first non-blank of `raw_source` → `source_tag` → `source` and additionally requires the backend's child-session flag, so a stale lower-priority field can't promote an independent row into a delegated one. Thanks @lowlandsheperd. (#7263) - **Remote (SSH/Docker) workspaces keep their target-side POSIX paths across session restore, streaming, uploads and project context.** When the terminal backend runs off-host, a workspace path such as `/srv/remote-alice` belongs to the *target* machine — but several resolvers normalized it against the WebUI host's filesystem, so a host-side expansion (macOS firmlinks turning it into `/System/Volumes/Data/srv/remote-alice`, or a local `~` expansion) could be persisted back onto the session and then used as the per-turn runtime CWD. The workspace, streaming, upload and project-context resolvers now receive the owning **session's profile** explicitly instead of resolving against whatever profile happens to be ambient, so remote paths stay target-side and a session owned by one profile can never resolve through another's. Local (non-remote) workspaces normalize exactly as before, and symlink/`..`/outside-root rejection is unchanged. Thanks @alfred-rootson.

The expensive canonical serialisation is memoised per content object for the duration of a single `merge_session_messages_append_only()` call (scoped through a `ContextVar`, keyed by object identity with the object held alive so an id can't be reused for a different list mid-call), restoring one serialisation per list per call. Empty/falsy content keys exactly as before. Thanks @totalitarian. (#7492) + - **An empty composer no longer inflates to fit its own placeholder on the JavaScript sizing path.** The fallback resizer measured `scrollHeight` for an empty textarea, which reflects the *placeholder* — so a long busy or compression hint (which wraps to two or three lines) grew the empty composer to roughly 71px, and only after a resize that happened while empty, making the resting height depend on history rather than content. The inline height is now cleared when the value is empty so CSS `min-height` defines the resting size, matching the native path. (#6760) - **Delegated subagent sessions nest under the conversation that spawned them instead of landing at the top of the sidebar.** The sidebar forces a *cross-surface* child row to top level when its parent row belongs to another surface (a Telegram/messaging parent), so an independent continuation doesn't get stacked under a foreign thread. A delegated subagent is also technically cross-source relative to its WebUI parent, so it was swept up by that rule and surfaced as a bare top-level row with no indication of what spawned it. Delegated subagents are now exempt from that branch and attach to their visible parent, while independent cross-surface continuations still stay top level. The delegated role is resolved in strict precedence order from the first non-blank of `raw_source` → `source_tag` → `source` and additionally requires the backend's child-session flag, so a stale lower-priority field can't promote an independent row into a delegated one. Thanks @lowlandsheperd.

Provider-qualified `@custom:` ids now resolve to the owning provider's own `base_url` and credentials. A `providers.` record with no endpoint fails closed with a terminal `CUSTOM_ROUTE_NO_ENDPOINT` (clearing any foreign connection bundle before construction or cache publication) rather than leaking another provider's endpoint, and cross-provider credential/base-URL isolation plus per-profile agent-cache signatures are preserved. Thanks @b3nw. (#7319) + - **Structured (multimodal) message content stored in `state.db` renders as its real content instead of a placeholder, without dropping or misattributing turns.** When the session projection decodes the `state.db` content sentinel, list-valued content now gets an out-of-band identity — a `("structured_content", canonical)` tuple that no scalar string can compare equal to — shared across the merge, dedup, content, and visible reconciliation keys, so an in-band string can't collide with a rich row and an image-only row can no longer vanish from the projection. The expensive canonical serialisation is memoised per content object for the duration of a single `merge_session_messages_append_only()` call (scoped through a `ContextVar`, keyed by object identity with the object held alive so an id can't be reused for a different list mid-call), restoring one serialisation per list per call. Empty/falsy content keys exactly as before. Thanks @totalitarian. (#7492) - **An empty composer no longer inflates to fit its own placeholder on the JavaScript sizing path.** The fallback resizer measured `scrollHeight` for an empty textarea, which reflects the *placeholder* — so a long busy or compression hint (which wraps to two or three lines) grew the empty composer to roughly 71px, and only after a resize that happened while empty, making the resting height depend on history rather than content. The inline height is now cleared when the value is empty so CSS `min-height` defines the resting size, matching the native path.

The prefix is now read in staged geometric reads, so an oversized field is recovered from the prefix instead of triggering a whole-file parse; a field beyond 1 MiB still falls back to the full parse rather than risking a truncated read. Legacy-sidecar caching remains gated on the file being legacy (its key includes `ctime_ns`, so a same-size rewrite still invalidates), modern sidecars are unaffected, and message/scene projections are byte-identical to before for normal, oversized-summary, oversized-scenes, and both-oversized sidecars. Thanks @rodrigogs. (#7573) + - **Models picked from a second custom provider group route to that provider's own endpoint instead of failing with a 400.** A model selected from a custom provider registered only under `custom_providers:` (picker value like `@custom:omni:antigravity/gemini-3.7-flash-tiered`) was resolved against the active provider's credentials, so it returned `HTTP 400 Invalid model format or no credentials for provider: `. Provider-qualified `@custom:` ids now resolve to the owning provider's own `base_url` and credentials. A `providers.` record with no endpoint fails closed with a terminal `CUSTOM_ROUTE_NO_ENDPOINT` (clearing any foreign connection bundle before construction or cache publication) rather than leaking another provider's endpoint, and cross-provider credential/base-URL isolation plus per-profile agent-cache signatures are preserved. Thanks @b3nw. (#7319) - **Structured (multimodal) message content stored in `state.db` renders as its real content instead of a placeholder, without dropping or misattributing turns.** When the session projection decodes the `state.db` content sentinel, list-valued content now gets an out-of-band identity — a `("structured_content", canonical)` tuple that no scalar string can compare equal to — shared across the merge, dedup, content, and visible reconciliation keys, so an in-band string can't collide with a rich row and an image-only row can no longer vanish from the projection. The expensive canonical serialisation is memoised per content object for the duration of a single `merge_session_messages_append_only()` call (scoped through a `ContextVar`, keyed by object identity with the object held alive so an id can't be reused for a different list mid-call), restoring one serialisation per list per call. Empty/falsy content keys exactly as before. Thanks @totalitarian.

Provider-qualified `@custom:` ids now resolve to the owning provider's own `base_url` and credentials. A `providers.` record with no endpoint fails closed with a terminal `CUSTOM_ROUTE_NO_ENDPOINT` (clearing any foreign connection bundle before construction or cache publication) rather than leaking another provider's endpoint, and cross-provider credential/base-URL isolation plus per-profile agent-cache signatures are preserved.

(#7598) - **The WebUI fails closed when the Agent's Git identity disappears, instead of risking a run on mixed module state.** `ensure_agent_runtime_current()` guards against executing a mix of old and new Python modules across an Agent update by comparing the on-disk Git revision to the one loaded in memory. When that revision became unreadable — the file deleted, permission-denied, empty, corrupt, the source directory removed, or the read itself raising — a missing revision is indistinguishable from a changed one and must not be treated as proof the loaded code is current. The guard now raises the typed stale-runtime error for every unreadable-identity case (surfacing as an HTTP 409, not a 500), with no forgeable file-metadata (`mtime`/size) fallback authorizing execution. `KeyboardInterrupt`/`SystemExit` still propagate, the matching-revision happy path is unchanged, and initially non-Git runtimes are unaffected.

The cost therefore grows with the rendered transcript, which is the "typing gets laggy in long sessions" report. Accept the natural one-row height as the skip ceiling, computed from the same already-read getComputedStyle. The strict finite-pixel gate is kept for every value involved, so a percentage / calc / normal line-height, padding or min-height still fails closed to the full resize (the #6349 re-gate property is preserved, and test_issue5514_composer_grow_scroll_pin.py still pins it). Measured on a 758-message / 5 MB session (31k DOM nodes rendered) with the browser Event Timing API (input -> next paint) at 6x CPU throttle: a keystroke went from 168ms to ~136ms median echo latency (72ms with the transcript detached), 96ms to ~72ms in the windowed state, and the style writes per 8 keystrokes from 16 to 2. The #5514 invariant holds: an oversized composer still takes the full resize because its offsetHeight is far above the one-row ceiling. Tests: - new tests/test_long_session_composer_typing_latency.py runs the real autoResize() body from messages.js in a node sandbox whose getComputedStyle returns the composer's computed styles; it is red before this change (2 failed, 27 passed) and green after (29 passed). - tests/test_issue5514_composer_grow_scroll_pin.py source pins updated to the new guard shape. * test(docs): address #7604 review - behavior-only tests + composer sizing docs Review feedback on the PR flagged two repo-rule items: tests that pin source strings, and an undocumented runtime behavior change. Both are addressed here. - tests/test_long_session_composer_typing_latency.py: delete test_fix_is_pinned_in_source. It asserted exact JS declarations, which the repo testing guidance rejects and which the harness in this module already covers by executing the REAL autoResize() body. In its place add test_natural_row_skip_survives_every_append_of_a_typed_word, which drives the actual typing loop ('' -> 'h' -> ... -> 'hello') and asserts zero height writes on every keystroke. Red on the pre-fix tree, green with the fix. - tests/test_issue5514_composer_grow_scroll_pin.py: convert test_single_line_growth_skips_the_height_round_trip from source-string pins to a behavior fixture whose getComputedStyle returns the composer's real computed styles. It asserts the observable outcome: a one-row append at the natural 48px row takes no height write, while an oversized 176px composer still remeasures back to one row. Red before the fix (2 writes), green after. - docs/UIUX-GUIDE.md: document the composer sizing invariants in the composer section - the single-row skip is a hot path and must stay reachable, its ceiling is the natural one-row height or the CSS min-height (whichever is larger), everything else still remeasures, and non-px computed values fail closed. ./scripts/test.sh on the two touched modules: 29 passed (3 failed on the pre-fix tree). Neighbour sweep over the 51 composer/scroll/typing modules: 386 passed. ruff check clean. * fix(tests,docs): derive composer test dimensions from style.css (#7604 review) Greptile's re-review is right: the fixtures hardcoded the 18px `data-font-size=large` composer (line-height 29.7px -> a 47.7px one-row box) as if it were the stylesheet's 16px default (44.4px). At the default the pre-fix ceiling (ceil(44)+1 = 45px) DID clear the one-row box, so the regression is font-size dependent - the 16px default reaches the skip, the 18px and 20px appearance settings do not - and not a stock-configuration bug. The runtime change is unaffected and unchanged. - new `tests/_composer_metrics.py`: parses `static/style.css` (the base `textarea#msg` rule, the `data-font-size` overrides, the skin overrides) and exposes each configuration's box metrics - natural one-row height, the integer offsetHeight a browser reports, and both the pre-fix and post-fix ceilings - so a fixture cannot encode the wrong font size again. - `tests/test_long_session_composer_typing_latency.py`: parameterized over every configuration the stylesheet can produce, with `test_the_regression_was_font_size_dependent_not_stock` pinning the grounding. - `tests/test_issue5514_composer_grow_scroll_pin.py`: the converted single-row test uses the same derived metrics. - `docs/UIUX-GUIDE.md`: the sizing section now states that the natural row tracks the appearance font size (44 / 48 / 51px) while `min-height` stays 44px, which is why a min-height-only ceiling silently disables the skip. Pre-fix tree: `4 failed, 31 passed` - exactly the large-18px and xlarge-20px parameterizations plus the two tests that assert the reported configuration. Post-fix tree: `35 passed`.

a/CHANGELOG.md b/CHANGELOG.md index 345df148..74c6fb52 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -9,6 +9,7 @@ ### Fixed +- **Typing in a long session no longer lags.** The composer's `autoResize()` has a fast path meant to skip an expensive measure-and-restore layout on every keystroke, but the guard enabling it compared the composer height against its CSS `min-height` (44px) rather than the height a single row actually settles at (line-height + padding + borders, ~48px), so the skip never fired in a real browser. Every keystroke then forced a full-document synchronous layout whose cost grows with the rendered transcript — on a ~750-message session this was ~168ms of echo latency per key versus ~72ms with the transcript detached. The fast path now compares against the real one-row height (tracking the appearance font size), so single-row typing skips the layout while any append that genuinely needs a taller composer still triggers a full resize. Thanks @KevinMeinon. (#7604) - **Live-follow no longer breaks mid-stream when content above the tail collapses.** A reader pinned flush at the bottom of the transcript was being unpinned whenever a section *above* the tail collapsed — a worklog "Done" fold, a thinking/tool card collapse, an interim-note collapse. The collapse shrinks the transcript height, the browser clamps the scroll position downward and fires a scroll event, and that was misread as the user scrolling away, killing live-follow while a response was still streaming. The scroll listener now only treats an upward scroll as intent when the reader has actually left the bottom, so an above-tail collapse keeps following the stream. Genuine upward scrolls still unpin immediately. Thanks @KevinMeinon. (#7605) - **Sidebar source-filter tabs are now localized.** The WebUI / CLI session-source tabs in the sidebar were hardcoded English (`WebUI sessions (N)` / `CLI sessions (N)`) and assigned straight to `textContent`, so they stayed English under every non-English locale. They now route through `t()` with the standard `{0}` count placeholder and are translated across all shipped locales. Thanks @Yularzhi. (#7602, #7580) - **Logging in with password auth enabled no longer lands on a 404.** After a successful login the server redirects to `/sessions`, but `/sessions` (plural) was missing from the SPA-shell route allowlist in `handle_get()` — only `/`, `/index.html`, and `/session/*` (singular) served the app shell — so an authenticated user was met with a `404 not found` immediately after logging in. `/sessions` (and `/sessions?query`) now serves the app shell like the other SPA entry points. Authentication is unchanged: `check_auth()` still runs before the route handler, so an unauthenticated `GET /sessions` still redirects to the login page with `next=/sessions`. The bug was invisible without auth because the SPA handles `/sessions` client-side and the server route was never hit. Thanks @Skawsk59.

Every one of those call sites now routes through t() and the plain strings live in the locale bundles. data-i18n is used for the static HTML (the same mechanism the other selects already use, per #7582 triage), and esc(t(...)) for the template-literal DOM built in panels.js so no injected text can introduce markup. Locale keys are added to all 15 shipped locale bundles (en, ru, it, ja, es, de, zh, zh-Hant, pt, ko, fr, cs, tr, pl, vi), following the same key-parity contract that the #7602 triage enforced for the sessions_source keys: inserted right after each locale's identity (_label:_speech_) line so the brace-bounded locale extraction still finds the whole block, matching the same pattern upstream used to fix the sessions_source parity. No locale falls back to English at runtime because t() resolves every bundle. tests/test_extensions_settings_panel.py: assertions that used to match the inline English strings now match the corresponding locale keys, and the state_unknown_ids hint asserts both the key is used and the raw English is gone. Verified: - python3 -m pytest tests/ -k "i18n or extension or parity or japanese" -q -> 496 passed - node --check on the three touched static assets -> all valid Fixes #7581.

The old paths only resolved through PLUGIN-COMPAT __getattr__ pointers that warn on every use and are removed on schedule by reverting one commit. With the pointers removed, every affected WebUI call site is wrapped in a broad except, so nothing crashes; features silently degrade instead: per-turn approval session-key binding is skipped, MCP discovery/status return nothing, /reload-mcp reports "MCP runtime unavailable", Claude Code credential linking returns None, every kanban connection raises AttributeError, and the dispatcher reports "unavailable". Add api.agent_compat.agent_attr, which resolves a moved name from the original module's own namespace first (pre-split Agents and existing test stubs), then from its new home (split Agents, with or without pointers), then plain attribute access (non-module doubles). Importing only the new modules would have broken pre-split Agents and bypassed the sys.modules stubs the test suite installs on the original modules. Names still native to their original module (_servers, _lock, has_blocking_approval, is_session_yolo_enabled, register/unregister gateway notify, the rest of kanban_db) are unchanged.

document the agent_compat contract Review follow-up for the Hermes Agent moved-name fix. Tests: replace the AST source guard with behavior tests that run each affected WebUI entry point against two fake Agent shapes, pre_split (name on the original module) and pointer_removed (name only in its new home): approval session identity bind/reset, MCP runtime status, /reload-mcp, Claude Code credential read, LM Studio reasoning options, and kanban connections (closed after use), board counts, SSE event feed, and dispatch. All 8 pointer_removed cases fail against the pre-fix call sites; the pre_split cases pass on both.

-9,6 +9,8 @@ ### Fixed +- **`.zip` artifacts now open from chat instead of silently failing.** A `MEDIA:/path/to/file.zip` link always failed to open: `.zip` was absent from `MIME_MAP`, so archives resolved to `application/octet-stream`, which the session `MEDIA:` token allow-list rejects. `.zip` now maps to `application/zip` and archives are admitted to the session-token type set. Archives are download-only by construction — the new `_ARCHIVE_TYPES` set is never added to either inline-preview set, so a zip always gets `Content-Disposition: attachment` and can never render inline (verified including `inline=1` and an uppercase `.ZIP` suffix). Path confinement is unchanged: a session token still grants only the exact canonical path an assistant-emitted token referenced, and the state/secret deny guard still runs ahead of the allow decision. Thanks @carlotestor. (#7612) +- **WebUI no longer depends on Hermes Agent compatibility shims that have already passed their removal date.** The Agent's September 2026 decomposition moved several names WebUI imports (`tools.approval`, `tools.mcp_tool`, `hermes_cli.kanban_db`, …) into sibling modules, leaving the old paths resolvable only through PEP 562 `__getattr__` pointers scheduled for deletion on 2026-09-14. Because every affected call site is wrapped in a broad `except`, losing those pointers would not have crashed anything — features would have degraded *silently*: MCP tools missing from turns, the per-turn approval session key never binding, Claude Code credential linking stopping, and the kanban bridge raising `AttributeError`. A new `api/agent_compat.py::agent_attr()` resolves each moved name from the original module's own namespace first (pre-split Agents and test stubs), then the new home module (split Agents, with or without the pointers), then plain attribute access — so WebUI works across all three Agent shapes and stops emitting `HermesPluginCompatWarning`. Thanks @mikemchargue. (#7574) - **Typing in a long session no longer lags.** The composer's `autoResize()` has a fast path meant to skip an expensive measure-and-restore layout on every keystroke, but the guard enabling it compared the composer height against its CSS `min-height` (44px) rather than the height a single row actually settles at (line-height + padding + borders, ~48px), so the skip never fired in a real browser. Every keystroke then forced a full-document synchronous layout whose cost grows with the rendered transcript — on a ~750-message session this was ~168ms of echo latency per key versus ~72ms with the transcript detached. The fast path now compares against the real one-row height (tracking the appearance font size), so single-row typing skips the layout while any append that genuinely needs a taller composer still triggers a full resize. Thanks @KevinMeinon. (#7604) - **Live-follow no longer breaks mid-stream when content above the tail collapses.** A reader pinned flush at the bottom of the transcript was being unpinned whenever a section *above* the tail collapsed — a worklog "Done" fold, a thinking/tool card collapse, an interim-note collapse. The collapse shrinks the transcript height, the browser clamps the scroll position downward and fires a scroll event, and that was misread as the user scrolling away, killing live-follow while a response was still streaming. The scroll listener now only treats an upward scroll as intent when the reader has actually left the bottom, so an above-tail collapse keeps following the stream. Genuine upward scrolls still unpin immediately. Thanks @KevinMeinon. (#7605) - **Sidebar source-filter tabs are now localized.** The WebUI / CLI session-source tabs in the sidebar were hardcoded English (`WebUI sessions (N)` / `CLI sessions (N)`) and assigned straight to `textContent`, so they stayed English under every non-English locale.

No information is lost — the ten rules remain in `docs/GUIDELINES.md`, which the new version still points to. Thanks @steveafrost. (#7593) +- **The `/api/models` cache invalidation contract is documented.** `#7556` shipped a change to the catalog cache's source fingerprint, and its review flagged the surrounding contract as undocumented runtime behavior. `docs/architecture/models-cache-invalidation.md` now records what is cached (in-memory snapshot, per-profile `models_cache.json`, cold vs hot path), the three source axes (`config_yaml` stat identity, `auth_json` content hash with a volatile-key deny-list, baked-in plus Codex catalog hashes) and why each is fingerprinted the way it is, and the invariant that both volatile-key sets are deny-lists that may only remove fields which provably do not gate the provider/model set. Changes no runtime behavior. Thanks @webtecnica. (#7560, #7556) + ### Changed - **The chat composer grows natively instead of being resized by JavaScript on every keystroke.** `autoResize()` measured `scrollHeight` and wrote `style.height` on each input event — a forced synchronous reflow on the most-typed-in surface in the app. Browsers that support CSS `field-sizing: content` (Chromium today; also Firefox 152 and Safari 26.2) now own the geometry directly, gated on `CSS.supports()`, and the existing JavaScript path is untouched for every other engine. Measured behaviour is identical across both paths: 44px resting height, no jump when the first character is typed or the last deleted, growth to the 200px ceiling, then internal scrolling. Because `field-sizing` deliberately includes placeholder text in content sizing, `:placeholder-shown` pins fixed sizing while the composer is empty so a long placeholder can't inflate it. Thanks @starship-s.

Memoize the verdict behind a bounded LRU, mirroring the existing redaction caches: entry count and per-entry size are both capped, so retained bytes stay bounded and oversized blobs simply run the scan uncached. Non-strings never reach the cache, so an unhashable value cannot raise. Measured on a real 22MB session, warm: full redaction 2.07s -> 1.07s (-49%), output byte-identical. Combined with the large-string cache, the recurring redaction cost drops from ~8.4s to ~1.1s. Rejected alternative, kept in a comment: collapsing the 71 `in` scans into one compiled alternation is the obvious-looking fix but measured 38% SLOWER (2.60s vs 1.88s) — CPython's substring search is already a tuned C routine. Security: the prefilter gates the entire redaction pass, so equivalence is pinned by a differential test suite against a copy of the previous implementation — every marker individually, case variants, embeddings, near-misses, unicode lowercase traps, 4000 fuzz cases, plus oversized and unhashable inputs. Verdicts are identical on all 73,658 strings of a real session (1935 flagged before and after).

The large-string LRU was keyed on input text only. The installed agent.redact registry can extend the secret matcher at runtime via register_redaction_patterns() and exposes no policy generation or invalidation hook, so a >16k string primed before a registration was served with the new secret intact (reproduced against the installed registry). Drop the large-string cache: strings above 16,384 chars run the redactor uncached again. Regression primes a large string, registers a runtime pattern on the real registry and proves the next redact_session_data() response is redacted. 2. The prefilter LRU was count-bounded (8192) but its per-entry gate was a character cap, which is not a byte bound: 16k four-byte code points is ~64 KiB per key, ~512 MiB at capacity, and the workload died with MemoryError under 96 MiB of headroom. Gate each entry on sys.getsizeof(text) <= 2048 so the retained-key ceiling is a hard 16 MiB. Regressions cover max-width Unicode, sensitive verdict pairs, eviction past the cap, and a low-memory RLIMIT_AS subprocess. --- api/helpers.py | 61 +++--- tests/test_redact_large_string_cache.py | 148 ++++++++------ tests/test_sensitive_prefilter_equivalence.py | 189 +++++++++++++++++- 3 files changed, 310 insertions(+), 88 deletions(-) diff --git a/api/helpers.py b/api/helpers.py index c53b402b..e049c1ab 100644 --- a/api/helpers.py +++ b/api/helpers.py @@ -9,6 +9,7 @@ import logging import os import re as _re import ssl +import sys from pathlib import Path from api.config import IMAGE_EXTS, MD_EXTS @@ -472,31 +473,26 @@ _redact_fn_lru = functools.lru_cache(maxsize=4096)(_redact_fn_uncached) # thousands of small recurring strings that actually benefit, or balloon RSS. _REDACT_CACHE_MAX_TEXT_LEN = 16384 -# Strings above that threshold used to bypass memoization entirely and re-run -# the full ~15-pass redactor on every request.

The session listing no longer self-heals idx_messages_session with CREATE INDEX (a writer lock held for minutes on a large messages table) — a missing index degrades to the pre-aggregated path. Cron sidebar info, insights and deep health checks in api/routes.py use the same read-only opener. Watcher (api/gateway_watcher.py): _poll_once returns without touching the database when nobody is subscribed, and forces a fresh full projection on the next subscription. Maintenance (scripts/ensure_state_db_read_indexes.py): the covering read indexes (idx_messages_session, idx_messages_session_role with NOCASE, idx_sessions_webui_fingerprint) are created only under --confirm-drained, optionally holding an exclusive flock on --lock-file for deployments that serialise agent turns on a lock file; existing indexes are verified for shape/collation and coverage (EXPLAIN QUERY PLAN), never silently replaced. Tests: tests/test_state_db_readonly_readers.py (read-only failure never retries writable; no poll without subscribers; listing creates no index; index tool requires drain, is idempotent, works without a lock file and refuses a held lock; cron sidebar read is mode=ro). Neighbouring tests that asserted the retired writable fallback / self-heal writer (test_issue3887_index_prime, test_issue5455_listing_readonly_connection, test_issue5455_lineage_readonly_reads, test_issue2628_cli_sessions_perf, test_issue1494_state_db_fd_leak) now assert the read-only contract; test_issue3506 subscribes before polling. --- api/agent_sessions.py | 57 +------- api/gateway_watcher.py | 6 + api/routes.py | 7 +- scripts/ensure_state_db_read_indexes.py | 98 ++++++++++++++ tests/test_issue1494_state_db_fd_leak.py | 6 +- tests/test_issue2628_cli_sessions_perf.py | 3 +- tests/test_issue3506_memory_and_watcher.py | 1 + tests/test_issue3887_index_prime.py | 34 +++-- .../test_issue5455_lineage_readonly_reads.py | 27 ++-- ...t_issue5455_listing_readonly_connection.py | 45 ++++--- tests/test_state_db_readonly_readers.py | 124 ++++++++++++++++++ 11 files changed, 303 insertions(+), 105 deletions(-) create mode 100644 scripts/ensure_state_db_read_indexes.py create mode 100644 tests/test_state_db_readonly_readers.py diff --git a/api/agent_sessions.py b/api/agent_sessions.py index 97086795..310df64d 100644 --- a/api/agent_sessions.py +++ b/api/agent_sessions.py @@ -24,30 +24,17 @@ def open_state_db_readonly(db_path: Path, log: logging.Logger | None = None) -> Same rationale as the session-listing path (#5455): a write-capable handle on the multi-GB, WAL ``state.db`` while the agent streams into it adds needless checkpoint/lock surface.

charset=UTF-8 Content-Transfer-Encoding: 8bit Review follow-ups on #7445 (nesquena-hermes CHANGES_REQUESTED + Greptile). api/agent_sessions.py - The read-only pre-aggregated `latest_messages` candidate ordering now applies to every missing-index projection (default sidebar, gateway watcher, cron/webhook/kanban views), not only `include_sources == ("cron",)`. Since the listing no longer self-heals the index, the correlated `MAX(mx.timestamp)` scan re-ran on every load: 9.86 s on a 5,000-session / 20,000-message DB vs 0.044 s after this change, with identical selected rows and order. The indexed seek is unchanged. - `state_db_file_uri()` / `state_db_readonly_uri()` replace `Path.as_uri()`: a UNC `HERMES_HOME` produced `file://server/share/...` and CPython's bundled SQLite (3.11-3.13 Windows builds, no SQLITE_ALLOW_URI_AUTHORITY) rejected the authority, so every agent-backed session vanished. The builder emits the empty-authority `file:////server/share/state.db?mode=ro`, keeps `file:///C:/...` for drive letters, strips `\\?\` / `\\?\UNC\` prefixes, quotes `?`/`#`, and leaves POSIX output byte-identical. Strict `mode=ro`, no writable fallback. scripts/ensure_state_db_read_indexes.py - `fcntl` / `msvcrt` are imported conditionally; the module imports and the no-`--lock-file` path runs on native Windows. `--lock-file` uses `flock` on POSIX, `msvcrt.locking(LK_NBLCK)` on Windows, and fails with a clear RuntimeError when neither exists. The rw open reuses the UNC-aware URI builder. docs/troubleshooting.md - Operator section: read-only contract, degraded missing-index listing, drained maintenance prerequisites, lock behaviour, failure modes, UNC. Tests: tests/test_pr7445_readonly_review_followups.py (19 tests, red before this change: correlated-subquery plan, missing URI builder, ImportError on fcntl). Query-plan contract via EXPLAIN QUERY PLAN — no CORRELATED SCALAR SUBQUERY on missing-index listings, identical rows to the indexed listing; platform-parametrised URI cases; maintenance module imported with `sys.modules["fcntl"] = None`. test_issue2628 no longer pins the cron-only gate; the flock-held test skips without fcntl. --- api/agent_sessions.py | 59 +++- docs/troubleshooting.md | 30 ++ scripts/ensure_state_db_read_indexes.py | 35 ++- tests/test_issue2628_cli_sessions_perf.py | 3 +- .../test_pr7445_readonly_review_followups.py | 262 ++++++++++++++++++ tests/test_state_db_readonly_readers.py | 2 +- 6 files changed, 379 insertions(+), 12 deletions(-) create mode 100644 tests/test_pr7445_readonly_review_followups.py diff --git a/api/agent_sessions.py b/api/agent_sessions.py index 310df64d..6c5691d9 100644 --- a/api/agent_sessions.py +++ b/api/agent_sessions.py @@ -1,8 +1,10 @@ """Shared helpers for reading Hermes Agent sessions from state.db.""" import logging import sqlite3 +import sys from contextlib import closing -from pathlib import Path +from pathlib import Path, PurePosixPath, PureWindowsPath +from urllib.parse import quote logger = logging.getLogger(__name__) @@ -18,6 +20,49 @@ logger = logging.getLogger(__name__) _SOURCE_COLUMN_WARNED_DB_PATHS: set[str] = set() +def state_db_file_uri(db_path, platform: str | None = None) -> str: + """Build the ``file:`` URI (no query string) for an absolute ``state.db`` path. + + ``Path.as_uri()`` is not usable here: for a UNC share it emits + ``file://server/share/state.db`` and SQLite rejects any non-local URI + authority unless compiled with ``SQLITE_ALLOW_URI_AUTHORITY`` (the + CPython 3.11-3.13 Windows builds are not).

Add one `_isSkillDisabled()` gate in static/commands.js and apply it at the two places that turn `/api/skills` rows into completions: * `_buildSkillCommandEntry()` returns null for a disabled skill, which keeps `_skillCommandCache` (and every consumer of it, including the dropdown) clean; * `_loadSlashSkillSubArgs()` skips disabled skills when building `/use` sub-args.

Because ensureSkillCommandsLoadedForAutocomplete() only re-loads while !_skillCommandCacheReady && !_skillCommandLoadPromise, no later picker pass ever retried: skill commands stayed missing until a page reload even after the API recovered. Readiness is now set only after a successful current-generation commit; the promise is cleared either way so the next pass can retry. The stale-generation fence is unchanged (verified a reply from the outgoing profile still refuses to commit). This wedge is PRE-EXISTING on master (its finally sets ready unconditionally), not introduced by this PR — fixed here because this change already reworks the surrounding generation handling. Adds a reject-once/recover regression plus a __failSkillsOnce() harness knob; reverting the fix turns it red.

Those subcommands now fall through to the normal send path using the existing opt-out contract that `/reasoning` already uses. Covers every alias the agent handler accepts, including `apply`, `deny` and `drop`, which a first pass missed. Thanks @totalitarian. (#7623) +- **Disabled skills are no longer offered by the slash-command picker.** Skills in `skills.disabled` are already excluded from the backend skill-command map, but the WebUI listed every `/api/skills` entry regardless — so a disabled skill stayed selectable in both `/use ` sub-args and the `/`-prefix skill suggestions. Both surfaces now share one filter. Switching profiles is also fenced: an `/api/skills` reply still in flight when the switch lands can no longer commit, so a payload generated for the outgoing profile cannot keep hiding a skill that is enabled in the new one. Separately, a transient `/api/skills` failure no longer wedges the picker — readiness was previously published even when the request rejected, which left an empty cache marked authoritative and stopped the composer from ever retrying until a page reload. Thanks @webtecnica. (#7511, #7509) + ### Documentation - **`AGENTS.md` now routes contributors to the references that match their change.** The old "read first" list asked for four files up front regardless of what was being changed, and carried a compressed copy of the ten change guidelines that `docs/GUIDELINES.md` owns. It now maps each reference to the kind of work it applies to and states explicit completion/verification criteria instead. No information is lost — the ten rules remain in `docs/GUIDELINES.md`, which the new version still points to. Thanks @steveafrost. (#7593) From d24d6377f906f5e7621237fe60d2b591c3b0564f Mon Sep 17 00:00:00 2001 From: happy5318 Date: Fri, 18 Sep 2026 11:24:51 +0800 Subject: [PATCH 106/446] perf(api/session): bound recovery calls; add msg_limit=all escape hatch Fixes the #7310 stall class: six frontend recovery paths (offline/bfcache refreshSession, stream-end settle, cancel sync, /compress preflight, /retry, /undo) issued bare GET /api/session reads that re-walked, re-redacted and re-serialized the ENTIRE transcript (4-15s / 28MB on a 5k-row session, #7625), and the same shape shipped the full session-level tool_calls list because windowing was gated on msg_limit being present. Changes: - Server: add explicit msg_limit=all escape hatch; window session-level tool_calls by actual truncation (length comparison) instead of the presence of a limit parameter. The bare no-limit shape keeps its full-transcript contract (pinned by test_state_db_reconciliation_preserves_sidecar_order_when_timestamps_collide and the run-journal snapshot test). - Client: refreshSession / _restoreSettledSession / cancel sync / /compress preflight / /retry / /undo now request the bounded tail (msg_limit=30) and restore the _messages_truncated/_messages_offset paging gate instead of hardcoding 'not truncated'; jump-to-start (_ensureAllMessagesLoaded) and outline jump opt in to the full transcript via msg_limit=all. Tests: test_session_default_window.py covers helper semantics, per-call-site bounded/all shapes, truncation-signal restoration, and a regression guard that no bare GET /api/session fetch remains in static/. 454 related tests pass; reverse-verified (reverting the fixes turns the tests red). --- api/routes.py | 43 ++++++- static/commands.js | 20 +++- static/messages.js | 21 +++- static/outline.js | 12 +- static/sessions.js | 2 +- static/ui.js | 6 +- tests/test_session_default_window.py | 172 +++++++++++++++++++++++++++ 7 files changed, 252 insertions(+), 24 deletions(-) create mode 100644 tests/test_session_default_window.py diff --git a/api/routes.py b/api/routes.py index 7d30ab90..474fc229 100644 --- a/api/routes.py +++ b/api/routes.py @@ -8977,9 +8977,11 @@ def _parse_msg_limit(raw): """Parse and clamp the ``?msg_limit=`` query value.

When it lazily minted a "Webhooks" / "Cron Jobs" project for a profile that had webhook/cron rows, ensure_webhook_project() and ensure_cron_project() tagged the new entry with get_active_profile_name() -- the UI-selected profile -- instead of the profile whose rows triggered it. A webhook-only profile therefore leaked a "Webhooks" project onto whichever profile was selected; deleting it did nothing because the next sidebar poll re-minted it, and switching profiles minted one per profile. ensure_webhook_project / ensure_cron_project / _profile_has_user_projects now take an explicit profile (default: active profile), and the scan passes _cli_profile through, so the opt-in gate and the tag both key on the scanned profile.

lock The session-field half of _cleanup_chat_start_launch_failure mutated and saved the passed-in session object without holding the per-session lock and without re-resolving the canonical session. A concurrent successor turn (same session_id, new stream_id) or a delete could be clobbered: pending fields wiped or a deleted session resurrected via save(). Mirror the established #1533 pattern (routes.py:3077) and anchor-scene write guard (routes.py:5140): hold _get_session_agent_lock, re-resolve with get_session(), early-return on KeyError (session deleted) or when the canonical no longer points at the failed stream, then reset pending fields on the canonical object only. Add deterministic race coverage: successor admitted during the check-then-clear window keeps its pending fields and is not saved away, and a deleted session is not resurrected by save(). Both tests fail against the previous implementation. --- api/routes.py | 42 +++-- .../test_issue6869_gateway_launch_failure.py | 150 ++++++++++++++---- 2 files changed, 144 insertions(+), 48 deletions(-) diff --git a/api/routes.py b/api/routes.py index b73ec9af..da9537b3 100644 --- a/api/routes.py +++ b/api/routes.py @@ -22817,21 +22817,33 @@ def _cleanup_chat_start_launch_failure(session, stream_id: str) -> None: with STREAMS_LOCK: STREAMS.pop(stream_id, None) STREAM_GOAL_RELATED.pop(stream_id, None) - if getattr(session, "active_stream_id", None) != stream_id: - return - session.active_stream_id = None - session.pending_user_message = None - session.pending_attachments = [] - session.pending_started_at = None - session.pending_user_source = None - try: - session.save() - except Exception: - logger.debug( - "Failed to persist chat-start cleanup after worker launch failure for %s", - stream_id, - exc_info=True, - ) + # The session-field reset needs the same concurrency discipline as the + # registry half: hold the per-session lock and re-resolve the canonical + # session before clearing anything.

Both are fixed here with revert-sensitive regressions. 1. Collidable sentinel. Table-row
was stashed as a fixed \x00BR\x00 token and that token was unconditionally rewritten back to
afterwards, so user-supplied text containing the literal token was corrupted -- in prose it became a
, and inside a link URL it broke the anchor apart. Replaced with conditional conversion:
becomes a newline only on non-table-row lines, so no placeholder is ever introduced and nothing user-suppliable is rewritten. 2. Lost HTML emphasis. The stricter italic regex (which correctly stops 'a * b * c' from italicising) also rejected the '* x *' produced by the / pre-pass, so ' italic ' degraded to literal asterisks -- and to a bullet list at line start. Boundary whitespace is now kept OUTSIDE the generated delimiters. Verified against the real renderMd(): output for both cases now matches master, while the table-cell
and spaced-asterisk fixes still hold. A revert probe confirms all five new regressions fail against the defective implementation.

      on every unclassified line. Verified: all non-table cases now match master byte-for-byte, while genuine multi-row tables keep
      in every data cell.

A profile-home symlink can be retargeted while the long-running webui process stays up, and _safe_resolve() deliberately falls back to the unresolved input after a transient OSError/RuntimeError/ValueError -- a process-lifetime cache would serve either a stale symlink target or a stale fallback forever. Redesign: replace the module-level dict with a contextvars.ContextVar that defaults to None (no active scope -> resolve fresh, exactly like pre-PR behavior). profile_home_resolve_cache_scope() sets it to a fresh dict for the duration of one call and resets it in a finally block, so no cache entry survives past that call. It now wraps only _load_cli_sessions_uncached as a decorator -- the actual N+1 hot loop (hundreds of Session.__init__ calls per sidebar build, each resolving the same profile argument). All other call sites of _resolve_profile_home_param (confirmed via repo-wide grep: all internal to api/workspace.py, none elsewhere) get fresh resolution on every call, same as before this PR existed. Rewrote tests/test_profile_home_resolve_caching.py to prove: (a) repeated resolves within one scope still hit the cache once, (b) two separate scopes (simulating two requests) do not share state -- a symlink change between them is observed on the second scope, and (c) calls outside any scope never cache at all.

` in a cell, and spaced asterisks stop turning italic.** Models routinely emit `
` inside a table cell to stack values on separate lines. `renderMd()` converted every `
` to a newline *before* the table parser ran, so the row split in half: the table rendered with a stub first cell and the remaining rows spilled out underneath as raw pipe text. Separately, the inline emphasis rule matched across spaces, so ordinary prose like `2 * 3 * 4 = 24` rendered as `2 3 4`. `
` is now converted only outside genuine table blocks — classified with the same grammar the table parser itself uses (a run of pipe-lines whose second line is a separator), so pipe-delimited prose such as `| note
# heading |` keeps its heading and list rendering — and emphasis no longer matches a leading or trailing space. Hardened during review: the first implementation used a fixed internal placeholder that user text could contain (corrupting prose and breaking link anchors), and its stricter emphasis rule silently dropped ` spaced `; both are fixed, with the sanitizer still stripping every attribute from a preserved `
`. Thanks @JayaMegelar. (#7618) +- **The Extensions settings pane is localized.** Gallery, Installed and Diagnostics were the last large user-facing surface still rendering hardcoded English. Every visible string in the pane now routes through `t()`, with translations supplied across all 15 shipped locales; each referenced key is present in every locale block, so no string can fall back to a raw key name. Extension names and author-supplied descriptions stay as written — they are third-party metadata, not UI chrome. Thanks @Yularzhi. (#7619, #7581) - **`/skills pending` and the other write-approval subcommands reach the agent again.** The WebUI's local `/skills` handler swallowed every argument into its own skill-name search, so the agent-owned write-approval subcommands never reached their handler — `/skills pending`, `/skills approve 3`, `/skills diff` and friends silently ran a name search instead of doing anything. Those subcommands now fall through to the normal send path using the existing opt-out contract that `/reasoning` already uses. Covers every alias the agent handler accepts, including `apply`, `deny` and `drop`, which a first pass missed. Thanks @totalitarian. (#7623) - **Disabled skills are no longer offered by the slash-command picker.** Skills in `skills.disabled` are already excluded from the backend skill-command map, but the WebUI listed every `/api/skills` entry regardless — so a disabled skill stayed selectable in both `/use ` sub-args and the `/`-prefix skill suggestions. Both surfaces now share one filter. Switching profiles is also fenced: an `/api/skills` reply still in flight when the switch lands can no longer commit, so a payload generated for the outgoing profile cannot keep hiding a skill that is enabled in the new one. Separately, a transient `/api/skills` failure no longer wedges the picker — readiness was previously published even when the request rejected, which left an empty cache marked authoritative and stopped the composer from ever retrying until a page reload. Thanks @webtecnica. (#7511, #7509) From 93814b9629491eeb86b15e9c3ec98282cb951e52 Mon Sep 17 00:00:00 2001 From: hermes Date: Sat, 19 Sep 2026 00:43:06 +0100 Subject: [PATCH 124/446] fix(webui): use the memoized workspace closure in the webhook chip pass The webhook second-pass loop in _load_cli_sessions_uncached called get_last_workspace(profile=_cli_profile) directly per row instead of the _cli_workspace() closure the main/cron/kanban passes already use, so it paid its own redundant file reads/is_dir() probe on every webhook row even though the loop already sits inside the profile-home resolve cache scope. Flagged in PR #7636 review (greptile): this is the one concrete gap in an otherwise-correct fix. Also adds an integration-level regression test proving the actual N+1 this PR targets -- Session.__init__ constructed via _state_projection_sidecar_metadata's Session.load_metadata_only() fallback on a cold sidecar-metadata cache -- is deduped by @profile_home_resolve_cache_scope() on _load_cli_sessions_uncached, with a companion test showing the same fixture scales linearly (one filesystem resolve per row) when the scope is bypassed. This directly answers the review claim that the cache scope doesn't reach any Session construction: it does, verified by counting real _safe_resolve() filesystem calls rather than call counts on the memoizing wrapper alone.

[CORE] A successful /compress returns the full transcript, but _applyManualCompressionResult kept the bounded preflight's paging signals (_messagesTruncated/_oldestIdx). Render now restores them before renderMessages(), same ordering as settle/cancel paths. 2. [SILENT] _restoreSettledSession preservation used (prefix || suffix), so repeated identical turns (colliding _messageIdentityKey) made BOTH comparisons succeed and the prefix branch spliced at the wrong offset - silently dropping rows and duplicating others. The server truncation signal now decides the strategy: truncated => suffix-exclusive, untruncated => prefix.

The cached INFLIGHT entry kept `lastRunJournalSeq` (206 in the report) while its live assistant projection was gone; re-attach passed that cursor to the server as `after_seq`, so every journal event that rebuilds the message body was skipped and only the tail came back. A manual reload - a zero-floor replay - restored the message, which is what proves the server-side journal was complete the whole time. - `_inflightCanSeedJournalReplay()`: only recoverable live output (assistant content/reasoning, `lastAssistantText`/`lastReasoningText`, live DOM, tools, burst anchors, a populated anchor scene) authorises a nonzero replay floor. - `_runJournalReplayFloorForInflight()` / `_runJournalReplayEventIdForInflight()` gate BOTH halves of the cursor. The server reads `after_event_id` before `after_seq`, so zeroing the seq alone would still resume at the stale event id and skip the same range. - `_normalizeInflightReplayCursorForReattach()` re-validates the selected recovery object immediately before reattach (both `loadSession` reattach paths), so a cursor that outlived its projection cannot reach the wire. `_inflightHasVisibleLiveState()` keeps its keep-vs-discard role: a bare user row has to stay visible across a mid-turn reload until pending/live reconciliation runs, so replay authority lives in the floor predicate rather than overloading that contract.

` inside a table cell to stack values on separate lines. `renderMd()` converted every `
` to a newline *before* the table parser ran, so the row split in half: the table rendered with a stub first cell and the remaining rows spilled out underneath as raw pipe text. Separately, the inline emphasis rule matched across spaces, so ordinary prose like `2 * 3 * 4 = 24` rendered as `2 3 4`. `
` is now converted only outside genuine table blocks — classified with the same grammar the table parser itself uses (a run of pipe-lines whose second line is a separator), so pipe-delimited prose such as `| note
# heading |` keeps its heading and list rendering — and emphasis no longer matches a leading or trailing space. Hardened during review: the first implementation used a fixed internal placeholder that user text could contain (corrupting prose and breaking link anchors), and its stricter emphasis rule silently dropped ` spaced `; both are fixed, with the sanitizer still stripping every attribute from a preserved `
`. Thanks @JayaMegelar. (#7618) - **The Extensions settings pane is localized.** Gallery, Installed and Diagnostics were the last large user-facing surface still rendering hardcoded English. Every visible string in the pane now routes through `t()`, with translations supplied across all 15 shipped locales; each referenced key is present in every locale block, so no string can fall back to a raw key name. Extension names and author-supplied descriptions stay as written — they are third-party metadata, not UI chrome. Thanks @Yularzhi.

Delivery is proven end to end by a subprocess test that redirects and then closes `sys.stdout` and still observes the records on the real process stdout. Record format, destination and ordering are unchanged for a normal launch, the write is guarded so a broken sink can never break an HTTP response, and `SIGPIPE` is already ignored before serving starts. Thanks @DevNexsler. (#7643, #2684) - **The session list stops re-resolving the same profile home once per row.** Building the sidebar's session list called `_resolve_profile_home_param()` for every projected row, and each call did a real filesystem resolve of the same path — a production trace pinned 5-17 s of a slow `/api/session` build to that one call site, reached through `Session.__init__` on every sidecar-metadata cache miss. The resolve is now memoized for the duration of a single session-list build via a call-scoped `ContextVar` entered by `_load_cli_sessions_uncached`, so N rows sharing a profile pay one resolve instead of N. Outside that scope the memo is inert, so nothing else in the process can serve a cached path, and the scope is released on exit including on exception — a value resolved under one profile can never be served to another. The active workspace is hoisted the same way, since it returns the same value for every row in a scan. Thanks @totalitarian. (#7636) From 3163a91d1a6d45927c4dbe6939a135ef3ce554b4 Mon Sep 17 00:00:00 2001 From: happy5318 Date: Sun, 20 Sep 2026 02:19:43 +0800 Subject: [PATCH 136/446] # Cron edit/duplicate must round-trip a parseable schedule; bad input returns 400 (#7352) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Thinking Path The WebUI populates the editable schedule field from `schedule_display`, which is the human-readable label `once at 2026-08-28 16:00` for one-shot jobs. `saveCronForm()` then submits that exact string back to `POST /api/crons/update`. The Agent's `cron.jobs.parse_schedule()` rejects the display form with `ValueError` (it only accepts the canonical ISO timestamp). The route's earlier `try/except ValueError` block covered input normalization but not the `update_job()` call, so the parser exception escaped as HTTP 500. There are two independent failures to fix: 1. **Frontend** ships the unsafe display label as editable input. Both `openCronEdit()` (`static/panels.js:1593`) and `duplicateCurrentCron()` (`static/panels.js:1532`) use the same `schedule_display || schedule.expression` fallback. The cleanest fix is a shared helper that returns the canonical Agent-parseable value by schedule kind, matching the Agent's own schema: - `once` → `schedule.run_at` - recurring cron → `schedule.expr` (current schema; `expression` accepted for legacy payloads) - interval / legacy → the stored value, with `schedule_display` kept as a final fallback only when it isn't the `once at …` label. 2. **Backend** converts `ValueError` from `update_job()` into HTTP 400 with the parser message, so the WebUI can show a real validation toast instead of an opaque Internal Server Error. The 404 path (job not found) is preserved. ## What Changed - **`static/panels.js`** — add `_cronScheduleForEdit(job)` helper and use it in both `openCronEdit()` and `duplicateCurrentCron()`. The helper returns `schedule.run_at` for one-shot jobs, `schedule.expr` (or legacy `schedule.expression`) for recurring cron, and falls back to `schedule_display` only when it is not the `once at …` presentation form. `saveCronForm()` is unchanged — it still submits `schEl.value`, which is now the canonical field instead of the display label. - **`api/routes.py::_handle_cron_update`** — wrap the `update_job()` call in `try/except ValueError` and return HTTP 400 with the parser message. The earlier normalization try block stays untouched; the 404 check (`if not job`) sits outside the new try block so a missing job still returns 404. - **`tests/test_cron_edit_round_trip.py`** — new regression module with seven tests covering the helper contract (helper exists, both call sites use it, `saveCronForm` still submits the field by name), the route's 400-on-`ValueError` behavior, the preserved 404 path, and the happy-path 200. ## Why - Editing a one-shot cron job's scheduled time has been returning HTTP 500 since the WebUI's initial public release (per #7352 historical note), because the editable field round-trips the `once at …` display label straight to the Agent parser. - The backend regression is independent: even with a correct frontend, any user-typed invalid schedule text (or a programmatic caller) used to produce a 500 instead of a validation response. Both halves are required to deliver a "no more 500" user experience. ## Verification ``` $ .venv/bin/pytest \ tests/test_cron_edit_round_trip.py \ tests/test_cron_no_agent_edit.py \ tests/test_cron_model_override.py \ tests/test_cron_model_provider_picker.py \ tests/test_issue617_cron_profile_selector.py \ -v --no-header … ============================== 27 passed in 4.84s ============================== ``` Seven new tests cover both layers; twenty surrounding cron tests (no-agent edit, model override, model/provider picker, profile selector) stay green. ## Contract | Scenario | Before | After | | --- | --- | --- | | Open one-shot job for edit, change time, save | 500 (display label round-trips to parser) | 200, persisted with new `run_at` | | Open recurring cron job for edit | 200 (legacy `schedule.expression` chain) | 200, unchanged canonical field (`schedule.expr` first, `expression` as legacy fallback) | | Duplicate a one-shot job | 500 on first save | 200, populated with `schedule.run_at` from the source job | | Submit a `once at …` schedule value (programmatic / pre-fix frontend) | 500 | 400 with the parser message | | Submit any other unparseable schedule | 500 | 400 with the parser message | | Update a job that does not exist | 404 | 404 (preserved) | | Update a job with a valid canonical schedule | 200 | 200 (preserved) | ## Risks - **Frontend helper change**: I switched the editable field source for both edit and duplicate in one commit. `saveCronForm()` is untouched, so anything already rendered with the legacy chain (rare in practice — the helper is only called from these two functions) keeps working. The regression `test_save_cron_form_still_submits_schedule_value` pins the submit field name. - **New `try/except ValueError` in `_handle_cron_update`**: the earlier normalization try block (lines 24986–24998) is left exactly as-is. The new try block sits directly around `update_job()` only, so a `ValueError` from input parsing still surfaces before any persistence side effect. The 404 check is outside the new try, so a missing-job path cannot be misreported as 400. Both `test_cron_update_preserves_404_when_job_missing` and `test_cron_update_valid_schedule_still_succeeds` pin those contracts. - **Legacy `schedule.expression` payloads**: accepted as a back-compat fallback in `_cronScheduleForEdit` and in the route (the Agent schema is `expr`, but the parser still handles `expression` per the existing contract). If you prefer to drop the legacy fallback, the helper can be trimmed to `sched.expr` only. ## Model Used - Generated with `MiniMax-M3` via `happy5318/hermes-webui` worktree `/tmp/webui-worktrees/pr7352-cron-edit`, branch `fix/cron-edit-round-trip` (off `origin/master`). ## Related - Closes #7352 - Surface code: - `static/panels.js:1510` `duplicateCurrentCron` (uses helper) - `static/panels.js:1585` `openCronEdit` (uses helper) - `static/panels.js:1905` `saveCronForm` (submit path, unchanged) - `api/routes.py:24979` `_handle_cron_update` (new try/except) - `cron/jobs.py:785` `parse_schedule` (rejects the display form; Agent-side, not modified in this PR) - `cron/jobs.py:2199` `update_job` (the call that raises) - Test surface: new `tests/test_cron_edit_round_trip.py` --- api/routes.py | 12 +- static/panels.js | 32 +++- tests/test_cron_edit_round_trip.py | 240 +++++++++++++++++++++++++++++ 3 files changed, 281 insertions(+), 3 deletions(-) create mode 100644 tests/test_cron_edit_round_trip.py diff --git a/api/routes.py b/api/routes.py index b827c53f..599b02ee 100644 --- a/api/routes.py +++ b/api/routes.py @@ -25011,7 +25011,17 @@ def _handle_cron_update(handler, body): updates[k] = v except ValueError as e: return bad(handler, str(e)) - job = update_job(body["job_id"], updates) + # #7352: ``update_job`` re-parses the updated schedule through + # ``cron.jobs.parse_schedule``, which raises ``ValueError`` for + # display-form input like ``"once at 2026-08-28 16:05"`` (or any other + # user-typed garbage).

The Agent rebuilds schedule_display from whatever the WebUI submits, so the rewrite stuck and the user silently lost their phrasing. Only the `once at ...` label is unparseable; every other schedule_display form round-trips through parse_schedule(), so prefer it and fall back to expr/expression. The existing tests asserted on the SOURCE TEXT of the helper and stayed green through this defect. Adds four tests that EXECUTE the real helper out of panels.js via node; the natural-language case is red before this fix.

The Agent's schedule parser only accepts the canonical timestamp, so it raised — and the route's existing `ValueError` guard did not cover the `update_job()` call, so the failure escaped as a 500. The field now carries the canonical `run_at` for one-shot jobs, and genuinely unparseable input returns a 400 with the parser's message instead of a server error. Natural-language recurring schedules are preserved verbatim: hardening during review found that preferring the canonical cron expression rewrote a job scheduled as `every monday 9am` into `0 9 * * 1` on every edit or duplicate — and because the Agent rebuilds the display string from whatever is submitted, the rewrite stuck and the user silently lost their phrasing. Only the `once at …` label is unparseable, so every other display form is now kept as typed. Thanks @happy5318. (#7649, #7352) + +- **"Webhooks" and "Cron Jobs" projects stop appearing on profiles that have none.** `get_cli_sessions(all_profiles=True)` walks every profile's `state.db` in one request, and when the walk reached a profile holding webhook or cron rows it lazily minted the system project — stamping it with the **UI-selected** profile rather than the profile whose rows triggered the mint. So a webhook project from one profile materialized on whichever profile happened to be open, deleting it from `projects.json` did not help because the next sidebar poll re-minted it, and switching profiles produced another copy. Both mint paths now tag the scanned profile. Single-profile calls keep their previous behavior, and no existing project data is overwritten — a pre-existing mis-tagged entry stays until removed, alongside the correctly tagged one. Thanks @carlotestor. (#7630) + - **Multi-frame phone photos stop dragging down session responses.** Multi-Picture Format JPEGs — the multi-frame containers phone cameras routinely produce — were being rejected at the first EOI marker, so they missed the native-image exemption and were handed to the full text-secret scan instead. On a real 30-message payload carrying 12 such images that cost 8.4 s of redaction per response; it is now 0.63 s, with every image byte preserved and non-image output identical. The exemption is granted only after the container fully validates: declared extents must tile the file contiguously to EOF, every secondary JPEG must itself be valid, and malformed offsets, bad counts or sizes, either byte order, overlapping or nested extents, gaps, truncation and undeclared trailing bytes all fail closed back to the normal redaction path rather than being exempted. Parser work is bounded by the APP2 segment size and secondary parsing cannot recurse. Verified against 10 hand-built malformed headers and 20,000 deterministic mutations with no exception raised. Thanks @GeorgeCodes19. (#7641) - **HTTP access logs survive agent stdout capture.** Agent and tool code replaces or closes `sys.stdout` to capture subprocess output, and the server's per-request access records were being swallowed into that capture instead of reaching the service log — so requests made while a tool was running simply vanished from the log. Access-log records now go through a dedicated writer that owns its own duplicate of the process's original stdout descriptor, taken at import time before any agent code loads, so replacing or closing Python's `sys.stdout` can no longer intercept them. Delivery is proven end to end by a subprocess test that redirects and then closes `sys.stdout` and still observes the records on the real process stdout. Record format, destination and ordering are unchanged for a normal launch, the write is guarded so a broken sink can never break an HTTP response, and `SIGPIPE` is already ignored before serving starts. Thanks @DevNexsler.

A transcript with older (stale) markers plus a newer `compression_anchor_summary` that no loaded marker references therefore lost the current summary, which master still rendered. Decide the fallback from `_latestCompressionReferenceMessage()` (`referenceMessageRawIdx < 0`) instead of marker presence, and feed that decision into `_selectCompactionCardPlacements()` before any card node is built so the fallback is the single preserved-task owner and marker cards never attach the task list a second time. Add a render-level regression that executes the real `renderMessages()` over 220 messages, three stale markers, one preserved task-list message and a newer summary: the current summary is visible and exactly one task owner is rendered, in full, virtualized and server-truncated windows. --- static/ui.js | 38 +- tests/test_auto_compression_card.py | 2 +- tests/test_compaction_card_display.py | 14 + ...est_compaction_current_summary_fallback.py | 528 ++++++++++++++++++ 4 files changed, 570 insertions(+), 12 deletions(-) create mode 100644 tests/test_compaction_current_summary_fallback.py diff --git a/static/ui.js b/static/ui.js index 8d09cccd..e2c7b690 100644 --- a/static/ui.js +++ b/static/ui.js @@ -15373,7 +15373,11 @@ function _loadedCompactionMarkerRawIdxs(messages){ // A settled compaction whose marker sits before the server-loaded tail must // remain visible at the top of that tail.

Pre-window markers are now preserved and placed deterministically, and card placement is stable across repeated renders and window changes — verified to neither lose nor duplicate a card as the virtual window moves. Hardened during review: the settled current-summary card was created only when *no* compaction marker was loaded at all, so a transcript carrying older markers plus a newer summary that none of them referenced silently dropped the summary the session was actually operating under — marker presence is not proof that any marker matches. The fallback now keys on whether a loaded marker actually references the current summary, and participates in the single preserved-task-owner selection so the repair cannot duplicate the task card. Mid-compression, empty-summary, unmatched-anchor-key, first-compaction and matched-marker cases were each checked, and reverting the guard reproduces the original suppression. Thanks @ruizanthony. (#7124) + - **Editing or duplicating a one-shot cron job no longer returns HTTP 500.** The editable schedule field was populated from `schedule_display`, the human-readable label (`once at 2026-08-28 16:00`), and saving submitted that label straight back. The Agent's schedule parser only accepts the canonical timestamp, so it raised — and the route's existing `ValueError` guard did not cover the `update_job()` call, so the failure escaped as a 500. The field now carries the canonical `run_at` for one-shot jobs, and genuinely unparseable input returns a 400 with the parser's message instead of a server error. Natural-language recurring schedules are preserved verbatim: hardening during review found that preferring the canonical cron expression rewrote a job scheduled as `every monday 9am` into `0 9 * * 1` on every edit or duplicate — and because the Agent rebuilds the display string from whatever is submitted, the rewrite stuck and the user silently lost their phrasing. Only the `once at …` label is unparseable, so every other display form is now kept as typed. Thanks @happy5318. (#7649, #7352) - **"Webhooks" and "Cron Jobs" projects stop appearing on profiles that have none.** `get_cli_sessions(all_profiles=True)` walks every profile's `state.db` in one request, and when the walk reached a profile holding webhook or cron rows it lazily minted the system project — stamping it with the **UI-selected** profile rather than the profile whose rows triggered the mint. So a webhook project from one profile materialized on whichever profile happened to be open, deleting it from `projects.json` did not help because the next sidebar poll re-minted it, and switching profiles produced another copy. Both mint paths now tag the scanned profile. Single-profile calls keep their previous behavior, and no existing project data is overwritten — a pre-existing mis-tagged entry stays until removed, alongside the correctly tagged one.

The colon is overloaded here — it separates a `@provider:model` routing lane, and it also appears inside perfectly ordinary model names — so the label builder now takes the catalog as the authority for `@custom` entries and leaves a plain-lane model id whole. Labels are display-only: the original option value survives selection and is dispatched unchanged, so no routing behaviour moves. Catalogued, cold, empty, stale, host:port, leading- and trailing-colon and multi-colon names were each checked to stay non-blank and exception-free. Thanks @webtecnica. (#7401, #7240) + - **Context-compaction cards stay visible in long transcripts.** When a transcript grew past the virtualization window, the compaction markers explaining where context was compressed scrolled out of the rendered range and vanished, leaving no indication that compaction had occurred. Pre-window markers are now preserved and placed deterministically, and card placement is stable across repeated renders and window changes — verified to neither lose nor duplicate a card as the virtual window moves. Hardened during review: the settled current-summary card was created only when *no* compaction marker was loaded at all, so a transcript carrying older markers plus a newer summary that none of them referenced silently dropped the summary the session was actually operating under — marker presence is not proof that any marker matches. The fallback now keys on whether a loaded marker actually references the current summary, and participates in the single preserved-task-owner selection so the repair cannot duplicate the task card. Mid-compression, empty-summary, unmatched-anchor-key, first-compaction and matched-marker cases were each checked, and reverting the guard reproduces the original suppression. Thanks @ruizanthony. (#7124) - **Editing or duplicating a one-shot cron job no longer returns HTTP 500.** The editable schedule field was populated from `schedule_display`, the human-readable label (`once at 2026-08-28 16:00`), and saving submitted that label straight back. The Agent's schedule parser only accepts the canonical timestamp, so it raised — and the route's existing `ValueError` guard did not cover the `update_job()` call, so the failure escaped as a 500. The field now carries the canonical `run_at` for one-shot jobs, and genuinely unparseable input returns a 400 with the parser's message instead of a server error. Natural-language recurring schedules are preserved verbatim: hardening during review found that preferring the canonical cron expression rewrote a job scheduled as `every monday 9am` into `0 9 * * 1` on every edit or duplicate — and because the Agent rebuilds the display string from whatever is submitted, the rewrite stuck and the user silently lost their phrasing. Only the `once at …` label is unparseable, so every other display form is now kept as typed. Thanks @happy5318.

The Agent already stamps these items with `role: assistant` and a normalized phase (`agent/codex_responses_adapter.py::_message_item` and `_OutputScan._message`), and the rendering lane is owned by #6828. The WebUI's two consumers of those persisted rows, however, only read the outer `content` field: - `api/routes.py::_session_media_token_allows_path` flattens `message.get("content")` through `_message_content_text()` and scans it for `MEDIA:` tokens. - `api/media_snapshots.py::annotate_media_snapshots` does the same when annotating the settled transcript so previews can survive an in-place overwrite of the source file. For a safe image emitted only inside commentary, the browser request hits the real `_handle_media` route, owns the correct session_id and exact path, but is denied 403 by the auth predicate because it cannot see the assistant's persisted `MEDIA:` token. Symmetrically, the snapshot annotator never captures commentary artifacts, so a subsequent in-place overwrite rewrites history without a recoverable snapshot. The fix is the maintainer's narrow recommendation: one shared fail-closed public-assistant-text iterator in `api/media_snapshots.py` (`codex_commentary_text`), consumed by both the auth predicate and the snapshot annotator. Keeping the extraction in one neutral helper means the auth and capture paths cannot drift apart on a future change. The fail-closed predicate is a strict chain — outer role is `assistant`; item type is `message`; item role is `assistant`; item phase normalizes to `commentary`; content is a list; the part is textual `output_text` with a string `text` value. Every step that fails returns the safe empty string, so the helper is safe to concatenate with the existing top-level extraction. User rows, user sidecars, reasoning items, analysis/final phases, malformed parts, non-string `text` values, and arbitrary nested fields are all skipped. ## What Changed - **`api/media_snapshots.py::codex_commentary_text`** — new module-level helper that returns the concatenation of all public-text `output_text` parts inside assistant-owned `codex_message_items` with `phase: "commentary"`. The outer row role, item type, item role, item phase, content shape, and part type are all gated, so the helper is fail-closed and safe to concatenate with the existing top-level text extraction. - **`api/routes.py::_session_media_token_allows_path`** — inside the existing per-message loop, the per-row `text` is now the concatenation of `_message_content_text(message.get("content"))` and the new `codex_commentary_text(message)`. The exact-path, owning-session, safe-MIME, URL-rejection, hard-denied, and symlink guards are unchanged. The commentary helper is imported lazily inside the loop so this file does not pick up a new top-level dependency. - **`api/media_snapshots.py::annotate_media_snapshots`** — the per-row `text` is now the concatenation of the existing top-level string `content` and the new commentary helper output. The existing `media_re.findall()` and resolve/allow paths are unchanged, so otherwise-capture-eligible commentary previews are now snapshotted at settle time. The string pre-filter on `"MEDIA:" in text` is kept so the helper short-circuits before regex extraction when neither source contains a token. - **`tests/test_issue7565_codex_commentary_media.py`** — new regression module with eleven tests: a positive valid-shape test, six fail-closed tests (user outer role, wrong item type, wrong item role, wrong phase, non-output_text parts, non-string output_text text), a case-insensitive commentary-phase test, a malformed-input test, and two integration static tests pinning that the auth predicate and the snapshot annotator both consume the new helper. ## Why - A user-visible artifact that the agent emitted only inside commentary was returning 403 at the real `_handle_media` route boundary even with the correct owning session_id, and the artifact was never snapshotted at settle time. The fix restores parity with top-level public assistant content for the commentary phase specifically. - Symmetry between auth and capture matters: a token that auth admits must be one capture can stamp, otherwise the served bytes can desynchronize from the snapshot pointer and the in-place-overwrite survivor feature (#6922) silently breaks. Sharing the helper makes drift impossible. ## Verification ``` $ .venv/bin/pytest \ tests/test_issue7565_codex_commentary_media.py \ tests/test_media_inline.py \ tests/test_media_message_snapshots.py \ -q --no-header … ============================= 115 passed in 6.16s ============================== ``` Eleven new tests cover the helper contract and the integration points. The 104 surrounding media_inline / media_message_snapshots tests stay green. ## Contract | Outer role | Item shape | Helper result | Auth result | Snapshot result | | --- | --- | --- | --- | --- | | `assistant` | `{type:"message", role:"assistant", phase:"commentary", content:[{type:"output_text", text:"…MEDIA:…"}]}` | text surfaced | `MEDIA:` token found; existing exact-path / safe-MIME / owning-session guards apply | `MEDIA:` token snapshotted at settle time | | `assistant` | `{type:"message", role:"assistant", phase:"analysis", content:[{type:"output_text", text:"…"}]}` | empty | unchanged from existing top-level-only behavior | unchanged | | `assistant` | `{type:"message", role:"assistant", phase:"final", content:[{type:"output_text", text:"…"}]}` | empty | unchanged | unchanged | | `assistant` | `{type:"reasoning", …}` | empty | unchanged | unchanged | | `assistant` | item role `user` | empty | unchanged | unchanged | | `assistant` | item content not a list | empty | unchanged | unchanged | | `assistant` | part type `tool_call` / `image` / `input_text` (even with text containing `MEDIA:…`) | empty | unchanged | unchanged | | `assistant` | `output_text` with non-string `text` (dict / list / number) | empty | unchanged | unchanged | | `user` (outer role) | any sidecar | empty | unchanged (user rows already skipped) | unchanged | | `assistant` | no `codex_message_items` | empty | unchanged | unchanged | | malformed (`None`, `""`, list, string, missing role) | n/a | empty | unchanged | unchanged | The fix only widens the inspection surface for the one public-text sidecar shape; everything else stays exactly as it was, so existing safe-MIME, hard-denied, exact-path-equality, owning-session, URL-rejection, and symlink guards remain intact. ## Risks - **Commentary widening the inspection surface**: yes, by design. The widening is narrowly scoped to the outer-assistant / item-message / item-role-assistant / phase-commentary / part-output_text / string-text chain. The new tests pin every step in that chain and every out-of-chain shape that must remain rejected. - **Existing safe-MIME / hard-denied / exact-path / symlink guards weakened?** No. The `media_capture_allowed` predicate, the `MIME_MAP` lookup, the `Path(ref).expanduser().resolve() == target_resolved` equality check, the `if "://" in ref` URL rejection, the hard-denied state/secret paths, and the symlink protections are all unchanged. The only change is what text the regex sees. - **Agent producer change**: the helper reads the same shape the agent already stamps (`role: assistant`, `phase: "commentary"`, `content: [{type: "output_text", text: "..."}]`). A future producer change that adds a new phase or part type requires an explicit follow-up PR; the helper's comments document the precise chain. - **Helper duplication drift risk avoided**: by placing the helper in `api/media_snapshots.py` (the storage half) and having `api/routes.py` import it lazily inside the loop, both consumers go through one definition. A follow-up change to the helper's contract automatically applies to both call sites. ## Model Used - Generated with `MiniMax-M3` via `happy5318/hermes-webui` worktree `/tmp/webui-worktrees/pr7565-codex-media`, branch `fix/codex-commentary-media` (off `origin/master` via `ghfast` mirror — `origin` was still TLS recv-failing at PR creation time; the mirror was used for `git fetch` and `git worktree add` only; push goes through the `fork` remote as usual). ## Related - Closes #7565 - Surface code: - `api/media_snapshots.py` (new) `codex_commentary_text` helper - `api/routes.py::_session_media_token_allows_path` (modified to concatenate the helper output) - `api/media_snapshots.py::annotate_media_snapshots` (modified to concatenate the helper output) - Adjacent lanes (intentionally not folded in): - #7294 / #7297 (safe-MIME, session_id, snapshot query parameters) — independent contract - #6828 (persisted-commentary rendering / recovery) — frontend UI; the WebUI auth predicate does not assume or expand its rendering scope - Open PRs #7367 and #6923 — overlap the token-extraction sites but neither implements this commentary ownership rule, per the maintainer's open-PR search - Test surface: new `tests/test_issue7565_codex_commentary_media.py` --- api/media_snapshots.py | 82 ++++++- api/routes.py | 17 +- .../test_issue7565_codex_commentary_media.py | 218 ++++++++++++++++++ 3 files changed, 314 insertions(+), 3 deletions(-) create mode 100644 tests/test_issue7565_codex_commentary_media.py diff --git a/api/media_snapshots.py b/api/media_snapshots.py index b50c32a6..929c1431 100644 --- a/api/media_snapshots.py +++ b/api/media_snapshots.py @@ -228,6 +228,66 @@ def snapshot_path_for_digest(digest: str) -> Path | None: return candidate if candidate.is_file() else None +def codex_commentary_text(message) -> str: + """#7565: typed public assistant commentary carried in + ``codex_message_items`` is eligible for the same exact + session-scoped MEDIA: grant as public top-level assistant content. + + The Agent producer (``agent/codex_responses_adapter.py``) stamps + message items with ``role: assistant`` and a normalized phase. + Only the public ``commentary`` phase, only the textual + ``output_text`` part, and only when the outer row role is + ``assistant`` is honored.

WebUI's session MEDIA authorization and its snapshot capture both read only that outer field, so a `MEDIA:` token emitted during commentary was invisible to both — the artifact was never authorized for the session token and never snapshotted, leaving the user unable to open a file the assistant had just produced. Both consumers now inspect the commentary sidecars as well. The widening is confined to genuinely assistant-authored, correctly-phased items: role, type, phase and content checks all fail closed, so a user-authored message, a tool result or a malformed item cannot grant a path token. Every existing guard is unchanged — exact-path matching, MIME allow-listing, session ownership, profile visibility and the state/secret hard-deny all still run on anything discovered through the new route, and snapshot capture keeps its confinement without double-capturing an artifact already taken from outer content. Verified against the Agent's real producer shape plus an adversarial probe covering user/wrong-role/wrong-phase, denied-state, wrong-path, duplicate, malformed and 300k-item inputs. Thanks @happy5318. (#7654, #7565) + - **Custom model names containing colons are no longer truncated in the picker.** A model id like `ollamacloud/qwen3.5:397b` was cut at its internal colon, so the picker showed a mangled label and two models that differed only after the colon could render identically. The colon is overloaded here — it separates a `@provider:model` routing lane, and it also appears inside perfectly ordinary model names — so the label builder now takes the catalog as the authority for `@custom` entries and leaves a plain-lane model id whole. Labels are display-only: the original option value survives selection and is dispatched unchanged, so no routing behaviour moves. Catalogued, cold, empty, stale, host:port, leading- and trailing-colon and multi-colon names were each checked to stay non-blank and exception-free. Thanks @webtecnica. (#7401, #7240) - **Context-compaction cards stay visible in long transcripts.** When a transcript grew past the virtualization window, the compaction markers explaining where context was compressed scrolled out of the rendered range and vanished, leaving no indication that compaction had occurred. Pre-window markers are now preserved and placed deterministically, and card placement is stable across repeated renders and window changes — verified to neither lose nor duplicate a card as the virtual window moves. Hardened during review: the settled current-summary card was created only when *no* compaction marker was loaded at all, so a transcript carrying older markers plus a newer summary that none of them referenced silently dropped the summary the session was actually operating under — marker presence is not proof that any marker matches. The fallback now keys on whether a loaded marker actually references the current summary, and participates in the single preserved-task-owner selection so the repair cannot duplicate the task card. Mid-compression, empty-summary, unmatched-anchor-key, first-compaction and matched-marker cases were each checked, and reverting the guard reproduces the original suppression. Thanks @ruizanthony.

Thanks @webtecnica. + - **Images and files produced during Codex commentary are viewable again.** The Agent's OpenAI Codex Responses adapter persists user-visible assistant progress in `codex_message_items` with `phase: "commentary"` while the outer `content` field stays empty. WebUI's session MEDIA authorization and its snapshot capture both read only that outer field, so a `MEDIA:` token emitted during commentary was invisible to both — the artifact was never authorized for the session token and never snapshotted, leaving the user unable to open a file the assistant had just produced. Both consumers now inspect the commentary sidecars as well. The widening is confined to genuinely assistant-authored, correctly-phased items: role, type, phase and content checks all fail closed, so a user-authored message, a tool result or a malformed item cannot grant a path token. Every existing guard is unchanged — exact-path matching, MIME allow-listing, session ownership, profile visibility and the state/secret hard-deny all still run on anything discovered through the new route, and snapshot capture keeps its confinement without double-capturing an artifact already taken from outer content. Verified against the Agent's real producer shape plus an adversarial probe covering user/wrong-role/wrong-phase, denied-state, wrong-path, duplicate, malformed and 300k-item inputs. Thanks @happy5318. (#7654, #7565) - **Custom model names containing colons are no longer truncated in the picker.** A model id like `ollamacloud/qwen3.5:397b` was cut at its internal colon, so the picker showed a mangled label and two models that differed only after the colon could render identically. The colon is overloaded here — it separates a `@provider:model` routing lane, and it also appears inside perfectly ordinary model names — so the label builder now takes the catalog as the authority for `@custom` entries and leaves a plain-lane model id whole. Labels are display-only: the original option value survives selection and is dispatched unchanged, so no routing behaviour moves. Catalogued, cold, empty, stale, host:port, leading- and trailing-colon and multi-colon names were each checked to stay non-blank and exception-free. Thanks @webtecnica.

On a switch nothing about the sources changed, so the delete only forced a full cold rebuild (live provider fetch_models HTTPS calls, ~490k deepcopy calls) on the very next /api/models — several seconds on every switch. The disk cache is already keyed per profile and rejected on read when _models_cache_source_fingerprint() differs, so it is safe to keep. Add a delete_disk keyword (default True — every existing caller keeps the old behaviour) and have the switch route pass delete_disk=False. Regression tests cover: memory-only drop preserves the disk file, default call still unlinks it, the next get_available_models() serves the disk snapshot without a live rebuild, and the switch route opts out. Two existing zero-arg stubs of invalidate_models_cache accept **kwargs now. --- api/config.py | 13 +- api/routes.py | 9 +- tests/test_gateway_watcher_profile.py | 4 +- .../test_profile_switch_models_disk_cache.py | 126 ++++++++++++++++++ tests/test_trusted_header_auth.py | 4 +- 5 files changed, 147 insertions(+), 9 deletions(-) create mode 100644 tests/test_profile_switch_models_disk_cache.py diff --git a/api/config.py b/api/config.py index 979ce3f7..87c1ce06 100644 --- a/api/config.py +++ b/api/config.py @@ -8156,7 +8156,7 @@ def _get_fresh_memory_models_cache(now: float) -> dict | None: return None -def invalidate_models_cache(): +def invalidate_models_cache(*, delete_disk: bool = True): """Force the TTL cache for get_available_models() to be cleared.

These tests execute the real decision code instead. ## What Changed `tests/test_7628_recovery_window_integrity.py` (new, 5 tests): the bounded-settle splice decision is extracted verbatim from `static/messages.js` (from the terminal-marker detection through the `S.messages` assignment) together with its transitive pure dependencies, and driven through a Node VM with the paging signals as the only variable. - **Discriminating regression for the splice strategy.** The fixture is a visible window of three turns plus a terminal marker against a durable tail of the last turn with `_messages_truncated=true, _messages_offset=4`. On that shape the correct suffix splice yields `[u-3, a-3, marker]`, while the pre-fix `prefix || suffix` expression splices at the head offset and re-emits `u-2/a-2/u-3/a-3` — the duplication the gate reported. Verified to fail on the pre-fix expression and pass on the current one. - **Paging restore.** `_messagesTruncated` / `_oldestIdx` follow the response's own signals for both the truncated and untruncated shapes, so a successful `/compress` (bounded preflight, full-transcript response) cannot leave the preflight's window state behind. - **Source lock on the strategy selection.** The strategy must be a truncation-gated ternary; a bare `||` between the two comparisons is the defect. - **Source lock on the compress success path.** The paging restore must sit between the response assignment and `renderMessages()`, reading `data.session._messages_truncated` / `_messages_offset` rather than hardcoding `false`. ## Why It Matters Both findings are silent history corruption: a wrong splice drops or duplicates transcript rows, and a stale paging offset shifts every absolute index that edit / fork / regenerate addresses rows by. Neither surfaces as an error, so the regression has to observe the resulting row list. ## Verification - 5/5 pass on the current head. - Reverting only the strategy selection (`prefix || suffix` plus the head-offset splice) fails 2 of the 5 — the behavioural splice test and the source lock — confirming the tests bite rather than restate the diff. - `tests/test_session_default_window.py` + `tests/test_7628_recovery_paging.py` unchanged and green (30 items together with the new file). - `scripts/ruff_lint.py --diff origin/master`: no new violations. ## Contract Change None — tests only. ## Model Used Hermes Agent (step-5-preview). The discriminating fixture was derived by executing both the current and the reverted expression through the same harness and comparing the resulting row lists, not by reading the diff. ## Related #7628 (this PR), #7310 (slow /api/session under load), #7625 (bounded recovery measurement). --- tests/test_7628_recovery_window_integrity.py | 343 +++++++++++++++++++ 1 file changed, 343 insertions(+) create mode 100644 tests/test_7628_recovery_window_integrity.py diff --git a/tests/test_7628_recovery_window_integrity.py b/tests/test_7628_recovery_window_integrity.py new file mode 100644 index 00000000..f70964c4 --- /dev/null +++ b/tests/test_7628_recovery_window_integrity.py @@ -0,0 +1,343 @@ +"""Behavioural regressions for the #7628 review round-3 findings. + +The round-3 gate reproduced two data-integrity defects against the shipped +functions and asked for tests that reach them (the source-assertion suite +stayed green through both reproductions): + +1. **A successful `/compress` kept the bounded preflight's paging state.** + The success path assigned the full-transcript response without restoring + ``_messagesTruncated`` / ``_oldestIdx``, so after a compression that + returned 100 full rows the client still showed "70 older messages" and + every absolute transcript index was off by 70 — which is what edit / + fork / regenerate address rows by. + +2. **Prefix match won over suffix match when both succeeded.** A bounded + settle returns a *suffix* of the durable transcript, but the old + ``prefix || suffix`` expression preferred the prefix branch, so a + transcript with repeated identical turns spliced at the wrong offset: + ``u1/a1`` silently dropped, ``u3/a3`` duplicated. + +These tests execute the real decision code rather than grepping it: the +splice strategy block is extracted from ``static/messages.js`` verbatim and +driven through a Node VM with the paging signals as the only variable, and +the compress success path is asserted at source level for the restore +ordering (that block issues a live ``/api/session`` fetch, so driving it +would need a network). +""" +from __future__ import annotations + +import json +import shutil +import subprocess +from pathlib import Path + +import pytest + +from tests.js_source_extract import extract_function + + +ROOT = Path(__file__).resolve().parents[1] +MESSAGES_JS = (ROOT / "static" / "messages.js").read_text(encoding="utf-8") +COMMANDS_JS = (ROOT / "static" / "commands.js").read_text(encoding="utf-8") +NODE = shutil.which("node") + +pytestmark = pytest.mark.skipif(NODE is None, reason="node not on PATH") + + +# ── extraction helpers ─────────────────────────────────────────────────────── + +_SPLICE_DEPS = [ + "_messageIdentityKey", + "_isTerminalStreamErrorMarkerMessage", + "_streamRecoveryControlMessage", + "_filterRecoveryControlMessages", + "_carryForwardEphemeralTurnFields", +] + + +def _splice_block() -> str: + """The bounded-settle splice decision, verbatim from messages.js. + + Spans the terminal-marker detection and the prefix/suffix comparisons + through the ``S.messages`` assignment — the region the round-3 gate + patched.

When the pending turn's user row is older than the tail, the tail is a *newer* settled assistant row that can never match the pending **user** checkpoint, and the recovery path falls through into the append branch. The cancel/recovery tail then appends, after the valid final answer, a recovered user row, a `_partial` clone of the old journal, and a generic no-response error that survives reload in the durable transcript. The fix adds `_transcript_already_advanced_past_pending()` which scans the messages for any strictly-matching user row (content + timestamp + source + attachments) and, when one is found, looks for a later settled assistant row (no `_partial` / `_error` / `_recovered`). When that is the case, the helper returns True and the non-completed-journal branch clears only the stale pending fields and returns without appending any rows. Strict match is required so that a *new* user turn that happens to repeat the same prompt text (e.g. user re-sends the same question) is not misclassified as a stale advance. The regression guard is the existing `test_repeated_pending_prompt_uses_current_checkpoint_identity` which now passes alongside the new helper unit cases. The helper is a pure read; running recovery twice therefore produces the same outcome, satisfying the maintainer's idempotence requirement. Validation: 11/11 new tests pass (covers the strict-match distinction, the partial/error/recovered skip, and idempotence); 124/124 related stale-pending / sidecar-repair / recovery tests pass; py_compile clean. --- api/models.py | 95 +++++++ tests/test_issue6366_stale_cancel_recovery.py | 237 ++++++++++++++++++ 2 files changed, 332 insertions(+) create mode 100644 tests/test_issue6366_stale_cancel_recovery.py diff --git a/api/models.py b/api/models.py index 84a91b9c..de21e3d9 100644 --- a/api/models.py +++ b/api/models.py @@ -2438,6 +2438,78 @@ def _latest_user_matches_pending_text(messages, pending_text): return False +def _transcript_already_advanced_past_pending(session) -> bool: + """#6366: a stale pending user message whose content already appears + in the durable transcript as a user row, followed by a newer settled + assistant row, means the transcript has already advanced past this + pending turn.

Another runtime could own the run while guidance was enqueued on a stale local agent. Fail closed instead: the in-process worker now registers its active run with the explicit local backend tag (WEBUI_LOCAL_CHAT_BACKEND, the same "legacy" value webui_chat_backend_mode() returns), and cache-only Steer only enqueues agent.steer() on that tag. Gateway keeps its gateway_steer_queued outcome; a missing, empty, or foreign backend returns stream_dead without steering.

On a long run (22.7k events / 15MB) that rebuild took ~4.4s per session load and blocked the HTTP thread - the dominant cost of "switching to a session with a task running takes forever". Four output-preserving fixes: 1. Locate the journal without parsing it (`find_run_file`) and derive the durable summary from the single `read_run_events` parse instead of parsing the file twice (`find_run_summary` + `read_run_events`). The historical `find_run_summary` lookup is kept as the fallback when no journal file exists on disk. 2. Skip `metering` rows in the projection loop (~60% of a long live journal's bytes; nothing in the snapshot is built from them), while preserving the last_ts watermark they carry. 3. Collect reasoning deltas into a list and materialize lazily instead of `reasoning_text += chunk` (quadratic inside these closures: ~2.3s of the replay on a 9.7k-chunk run). 4. Fold only a bounded tail of the reasoning transcript for the interim-echo suffix check instead of `re.sub` over the whole growing text (~1.5s over 100+ probes). Measured on a 15MB / 22.7k-row live journal: 4.34s -> 0.49s (8.9x) with byte-identical snapshot output (sha256 of the canonical JSON unchanged). Related work: #7310 (slow /api/session under load), #7534 (incremental journal read cache - complementary: this removes one of the two parses entirely and fixes the replay-loop hotspots), #7273/#7291 (metering write-side skip - the read-side loop skip here complements them for legacy journals that still carry metering rows). --- api/routes.py | 82 +++++++++++++++++++++++++++++++++++++++------- api/run_journal.py | 21 ++++++++++++ 2 files changed, 91 insertions(+), 12 deletions(-) diff --git a/api/routes.py b/api/routes.py index 7bfa4347..cf1c86d7 100644 --- a/api/routes.py +++ b/api/routes.py @@ -3461,16 +3461,31 @@ def _run_journal_live_snapshot(stream_id: str | None, *, handler=None) -> dict | emit_error=False, ): return None - summary = find_run_summary(stream_id) - if not summary: - return None - session_id = str(summary.get("session_id") or "") - if not session_id: - return None + # Locate the run journal WITHOUT parsing it first. find_run_summary reads + # and parses the whole file (tens of thousands of rows on a long live + # run), and read_run_events below then parsed it AGAIN — two full passes + # cost ~0.6s per rebuild.

The same retired window existed in the reverse helper (_strip_compact_echo_suffix), pinned by its own test. Both now share _find_compact_echo_suffix_start: a backward walk over value/suffix that skips whitespace in value, inspects only the echo span, and allocates nothing. It restores the previous output semantics (origin/master folded the whole reasoning text) and is cheaper than the windowed version (no per-call tail fold). Tests: new journal-reconstruction regression (a 5000-space-stretched echo must appear exactly once; genuine interim text must not be treated as an echo), the suffix-helper oracle updated to window-free semantics, and the window-contract test now pins that a stretched echo IS stripped. --- api/routes.py | 19 ++-- api/streaming.py | 73 +++++++----- tests/test_compact_echo_suffix_linear_scan.py | 70 +++++------- tests/test_live_snapshot_echo_dedup.py | 104 ++++++++++++++++++ 4 files changed, 186 insertions(+), 80 deletions(-) create mode 100644 tests/test_live_snapshot_echo_dedup.py diff --git a/api/routes.py b/api/routes.py index cf1c86d7..de75c1fd 100644 --- a/api/routes.py +++ b/api/routes.py @@ -3592,20 +3592,16 @@ def _run_journal_live_snapshot(stream_id: str | None, *, handler=None) -> dict | tool_calls.append(call) def reasoning_echo_tail_matches(text: str) -> bool: - candidate = _compact_for_echo_compare(text) - if not candidate: - return False full = _materialize_reasoning_text() if not full: return False - # Suffix test — folding the WHOLE (growing) reasoning transcript per - # interim segment ran re.sub over hundreds of KB 100+ times per - # rebuild (~1.5s).

The window-free backward walk is correct, but it re-walks the raw reasoning transcript's whitespace once per interim event — on a whitespace-heavy transcript that span is megabytes, and the replay went ~55x slower than master on the production shape the gate measured (1MB / 20-interim journal: 0.035s master → 1.922s branch). ## Thinking Path The gate's finding was that the cost is structural, not a tweak: the matcher consults the *whole* accumulated transcript on every interim event, so any raw-text rescan of it is O(interim_count x whitespace_span). The fix is the data-structure change the review asked for — maintain the folded view and the raw cut offsets incrementally, and match/strip from that indexed state instead of rescanning the raw buffer. ## What Changed - `api/streaming.py`: new `_CompactEchoIndex` — an append-only folded index that records, per non-whitespace character, its raw index. `append` folds a chunk once (cost proportional to the chunk, never the buffer), `matches_tail`/`cut_to` compare only the candidate against the folded tail (O(len(candidate)), no raw walk), `reset` drops the state after the raw text is truncated. The old raw helpers (`_find_compact_echo_suffix_start`, `_strip_compact_echo_suffix`) stay as the equivalence oracle. - `api/routes.py::_run_journal_live_snapshot`: reasoning chunks feed the index as they are appended; `reasoning_echo_tail_matches` and `strip_reasoning_echo_tail` consult the index. The strip re-indexes the truncated transcript so later probes match against it. - `api/streaming.py` live path: the same swap for the live-stream echo strip. The three live reasoning buffers (STREAM_REASONING_TEXT, the coalescing buffer, the per-message segments) each carry a mirrored index, fed on every append and re-indexed after a strip. The buffer flush resets the buffer's index with the text it drops, so the index never describes text that is no longer there. - `docs/rfcs/webui-run-state-consistency-contract.md`: the echo-match clause now names the indexed representation and the scaling regression that pins it. ## Why It Matters Removing one quadratic by introducing another in the same hot path is the exact risk the gate flagged — the headline benchmark used a journal shape where the window-free walk's cost does not dominate, so the aggregate number still looked like a win. The index keeps the original 8.9x and adds the scaling guarantee on the shape that was regressing. ## Verification - Measured on the reproduced shape (1MB whitespace span, 20 interim events): 0.972s → 0.049s. Doubling both span and interim count scales ~2x per step (x1 0.041s / x2 0.090s / x4 0.175s) — linear, not quadratic. - Behaviour equivalence: 300 randomized journals (whitespace-heavy, Unicode, chunked, flagged/unflagged interims) rebuilt with the indexed implementation and with the raw walk swapped in — sha256 of the canonical snapshot JSON matched on all 300. - `tests/test_compact_echo_index.py` (new, 6 tests): oracle equivalence over 2000+ randomized cases, chunked-append equivalence, matches_tail/cut_to agreement, reset-after-truncation, and two cost probes that fail the raw walk. - `tests/test_live_snapshot_echo_scan_scaling.py` (new, 4 tests): the proportional-scaling regression the review asked for — verified to FAIL on the pre-fix matcher (14.6x time for 4x rows, the quadratic signature) and pass on the indexed one. - Existing echo/journal suites unchanged and green: 19 items across `test_compact_echo_suffix_linear_scan` / `test_live_snapshot_echo_dedup` / `test_live_snapshot_single_parse`, plus 66 neighbouring items (`test_issue1361_cancel_data_loss`, `test_issue2565_reasoning_accumulation`, `test_issue2713_streaming_segment_flush`, `test_cancel_interrupt`, `test_run_journal`). ## Contract Change None. The matcher's observable behaviour is unchanged (same cut points, same whitespace-insensitive semantics); only its cost profile changes. No config knobs, no API surface. ## Risks - Index drift: if a future writer mutates one of the reasoning buffers without feeding (or resetting) its index, the matcher would silently miss echoes. Mitigated by keeping the index feed adjacent to every existing write site and by the reset-on-flush/reset-on-strip symmetry; the equivalence test would catch a dropped feed as a missed echo. - Memory: the index stores one char plus one int per non-whitespace character. On a whitespace-heavy transcript this is bounded by the folded length, which is what the transcript would cost folded anyway; the raw text is still the larger object. ## Model Used Hermes Agent (step-5-preview) with direct file edits and pytest verification. Cost properties were measured with a purpose-built scaling probe (proportional span x interim count), not a fixed-size fixture; the probe is kept as a regression test rather than a script. ## Related #7569 (this PR), #7310 (slow /api/session under load), #7534 (incremental journal read cache — complementary), #7273/#7291 (metering write-side skip). --- api/routes.py | 50 ++-- api/streaming.py | 151 +++++++++++- .../webui-run-state-consistency-contract.md | 21 +- tests/test_compact_echo_index.py | 218 ++++++++++++++++++ tests/test_live_snapshot_echo_scan_scaling.py | 127 ++++++++++ 5 files changed, 526 insertions(+), 41 deletions(-) create mode 100644 tests/test_compact_echo_index.py create mode 100644 tests/test_live_snapshot_echo_scan_scaling.py diff --git a/api/routes.py b/api/routes.py index de75c1fd..db182efb 100644 --- a/api/routes.py +++ b/api/routes.py @@ -3513,6 +3513,10 @@ def _run_journal_live_snapshot(stream_id: str | None, *, handler=None) -> dict | # most once per interim segment. reasoning_parts: list[str] = [] reasoning_dirty = False + # Incremental folded index over the reasoning transcript: the per-interim + # echo probe consults this instead of re-walking the raw text (see + # ``_CompactEchoIndex``). + reasoning_index = _CompactEchoIndex() messages: list[dict] = [] tool_calls: list[dict] = [] activity_burst_anchors: list[dict] = [] @@ -3592,30 +3596,32 @@ def _run_journal_live_snapshot(stream_id: str | None, *, handler=None) -> dict | tool_calls.append(call) def reasoning_echo_tail_matches(text: str) -> bool: - full = _materialize_reasoning_text() - if not full: - return False - # Backward compact-suffix walk (no fixed window): linear in the echo - # length, allocation-free, and it cannot miss a compact-equivalent - # suffix whose raw span is stretched by interior whitespace.

Dead live-turn node. The assistant row is persisted a few ms before the stream's terminal event clears S.activeStreamId, so the #6948 preserve guard still treats a finished #liveAssistantTurn node as live. Both live-turn insertion paths (renderMessages()'s re-attach and restoreLiveTurnHtmlForSession()) have one branch that APPENDS a turn the settled rebuild did not produce; the leftover node keeps id=liveAssistantTurn, is re-preserved on every later render, and the duplicate survives until a reload. 2. Settled activity scene. A process_prose row whose text IS the final answer is suppressed by the transparent-stream renderer but rebuilt as a second .assistant-segment by the compact-worklog row builder. The existing near-equality matcher never fires for short answers because of its absolute shorter>=80 floor (the reported reproduction is a 35-char greeting). Dropping a live node is now an OWNERSHIP proof, never a text comparison: the transcript must end with a settled assistant message carrying this stream's id (_anchor_stream_id / scene identity), and the node must contain nothing the settled rebuild could not have produced (no unpersisted tool card, reasoning row, or second live segment). Unknown node shapes fail closed and keep the turn, so a genuinely live turn - including one whose text matches an earlier answer - is never dropped. The settled-scene half compares raw markdown at the single chokepoint both settled renderers share. Adds tests/test_issue2051_duplicate_assistant_answer.py: four tests that fail on the pristine tree and pass with this change, including a wiring test that fails loudly if either append branch loses its guard.

It survived reloads, was unreproducible on a clean machine, and could not be explained by any render path. The cause is outside the app. Privacy / anti-fingerprinting extensions wrap the DOM insertion APIs so they can re-scan the document after every mutation. The reporter identified CanvasBlocker 1.12 in their own profile; its `lib/iframeProtection.js` -> `protectDOMModifications()` wraps `appendChild`, `insertBefore` and `replaceChild` on Node.prototype, `append`, `prepend`, `insertAdjacentElement`, `insertAdjacentHTML`, `insertAdjacentText` and `replaceWith` on Element.prototype, and the `innerHTML` and `outerHTML` setters, and installs them with `exportFunction`, so they still stringify as `[native code]` and cannot be told apart from the real thing by the page. A wrapper that ends up executing the wrapped call twice is harmless for node-based insertion but not for string-based insertion. Measured on the reporter's exact 2342-char emit string, in Chromium 152 and Firefox 154: a doubled `insertAdjacentHTML` rendered 2 bodies before this change and 1 after, while a doubled `appendChild`, `insertBefore`, `append` or `innerHTML` setter rendered 1 body both before and after. Only the HTML-string path multiplies: `insertAdjacentHTML` parses and appends a fresh copy every time it runs, whereas appending a node MOVES it (a second call is a no-op) and an `innerHTML` setter REPLACES (a second call is idempotent). That is why exactly this one construct, of all the wrapped APIs, produced the duplicate -- and why switching to a different insertion API is a real fix rather than a workaround for one extension. Parse into a `
