The round-2 fix acquired _available_models_cache_lock in the resolver to read
the snapshot+fingerprint consistently. Codex found that introduces a DEADLOCK:
config-save takes _cfg_lock -> _available_models_cache_lock while catalog-refresh
takes _available_models_cache_lock -> _cfg_lock (lock-order inversion), and it
also makes every send wait behind a catalog rebuild.
Fix: publish an immutable (snapshot, publisher_fingerprint) tuple atomically via
_sync_models_cache_provenance() at every cache publish/invalidate site (9 sites),
and have _endpoint_advertised_model_ids read that single global with ONE lock-free
load. Reading one tuple can't tear (GIL), acquires no lock (no ordering edge, no
deadlock), and never blocks behind a rebuild. A reader racing a publish sees the
previous consistent pair, never a torn snapshot/fingerprint.
Verified: two-thread probe — resolver completes in 0.0001s while another thread
holds _available_models_cache_lock (was the deadlock). Real catalog build publishes
the provenance tuple and closes the P0 end-to-end. Adds a deadlock-regression test.
Codex regression gate found two real issues on the first cut:
1. extra_models bucket: a provider's advertised ids can be split across the
catalog's 'models' (visible) and 'extra_models' (picker overflow) buckets.
Reading only 'models' could miss a bare id that overflowed, leaving the
#433 stale prefix unstripped. _endpoint_advertised_model_ids now unions
both buckets.
2. Profile isolation (profiles are islands): _available_models_cache is a
process global, so a concurrently-active foreign profile could publish the
snapshot a different profile then reads for provenance — potentially
stripping an advertised full id against another profile's catalog. The
accessor now rejects the snapshot unless its published source fingerprint
(whose config_yaml axis is the profile-specific config path) matches the
current runtime fingerprint; any mismatch fails safe to verbatim preserve.
Adds tests: extra_models-counts-as-advertised (#433 via overflow bucket) and
foreign-profile-catalog-preserves-verbatim (isolation fail-safe). Test helpers
now stamp the source fingerprint exactly as the real publish sites do.
Resolve the model id for custom/proxy providers by ENDPOINT PROVENANCE
instead of a catalog-family guess. The old gate stripped a vendor prefix
whenever the bare id was first-party of the prefix's home vendor, which
could not distinguish a namespace the proxy actually routes on
(x-ai/grok-4.5 -> keep) from a stale cross-provider leftover on a relay
that only serves bare ids (openai/gpt-5.4 -> strip). A model graduating
into the first-party catalog (agent commit adding grok-4.5) silently
flipped a working custom-proxy id from preserved to stripped -> HTTP 400.
New _endpoint_advertised_model_ids() reads the already-published catalog
snapshot (never builds/probes/touches disk; O(1) per send via a
snapshot-identity memo) and answers what the endpoint advertised:
- full vendor/model advertised -> preserve (#5979, #3872, #548)
- only the bare id advertised -> strip the redundant prefix (#433)
- cold/unbuilt catalog -> preserve verbatim (fail-safe toward
the id the user actively selected)
The non-custom first-party-proxy strip arm is unchanged.
Rewrites the two pinned #433 tests to model provenance (bare-only
advertised) and adds #5979 coverage: advertised-full preserve (bare +
named custom), cold-catalog preserve-verbatim, and both-advertised
prefers-full.
Thanks @b3nw for the report and precise root-cause analysis.
34 test files read static/*.js via read_text()/open() without an encoding,
so Python's cp1252 default on Windows choked on non-Latin1 bytes and errored
at collection (Ubuntu CI defaults to utf-8, so it never saw this). Add
explicit encoding="utf-8" to those reads — purely mechanical, no assertion
changes.

PR #2521 (Geist Contrast skin) adds a scoped
`:root[data-skin="geist-contrast"] .session-item.active .session-title` rule
that legitimately uses its own palette values. The existing assertion in
test_sprint40_ui_polish.py matched on any line containing the
`.session-item.active .session-title` substring, picking up the skin-scoped
override and asserting against its palette.
Exclude lines containing `:root[data-skin=` from the base-rule scan so
skin-scoped overrides are free to use their own design tokens, while the
global rule still enforces var(--gold) / var(--accent-text).
Three related profile-switching fixes:
- Always persist hermes_profile=default cookie when switching back to default (was being cleared with max-age=0, causing fallback to process-global profile)
- Replace undefined updateWorkspaceChip() with syncTopbar() in the sessionInProgress branch of switchToProfile()
- Make sidebar/dropdown active-profile rendering prefer S.activeProfile client state when available, with safe fallback
Tests: 1854 passing.
Independent review by @nesquena confirmed all blockers resolved. Theme×skin two-axis system replaces old monolithic color schemes. Closes#627. Co-Authored-By: aronprins <aronprins@users.noreply.github.com>
Squash-merges PR #584 by @aronprins.
Drops the meta row (message count, model slug, source-tag badge) from every sidebar session item. Each session now renders as a single title line — visible session count roughly doubles at typical viewport height.
Changes merged verbatim from contributor branch, plus maintainer additions:
- CHANGELOG entry for v0.50.64
- Version badge bump to v0.50.64
- New test: test_relative_time_today_bucket (closes minor coverage gap from code review)

- sessions.js _formatSourceTag(): return null for unrecognised tags
instead of raw string — prevents legacy 'N/A' values from surfacing
- sessions.js metaBits push: guarded with _stLabel null check so only
known platform labels appear in the session metadata line
- sessions.js [SYSTEM:] title fallback: drop raw s.source_tag middle
term, fall back directly to 'Gateway' for unknown sources
