Salvaged from #4627 by @perejaslav. Core Hermes already supports
reasoning_effort=max; this closes the WebUI parity gap (Anchor-A) — adds
max to VALID_REASONING_EFFORTS + dropdown/chip/reasoning-command, keeps
the degrade ladder for capped models.

Opus final gate caught that the staged re-implementation placed the
window._showThinking===false gate in _worklogReasonNodeFromText, which has
ZERO callers — so live/settled reasoning rows (built by _syncWorklogReasonFromAnchor
and _appendWorklogReason) were never actually hidden, and removeThinking swept
data-worklog-reason-source=reasoning which the real rows (data-worklog-anchor-reason=1)
don't carry. The string-match tests passed against the dead function = green-suite blind spot.
Fix:
- Gate _syncWorklogReasonFromAnchor (live + settled): when _showThinking===false, remove any
existing reasoning row and bail before building.
- Gate _appendWorklogReason (settled rebuild): return null when _showThinking===false.
- removeThinking + the settled-rebuild cleanup now sweep BOTH data-worklog-anchor-reason=1
(the real attribute) and the legacy data-worklog-reason-source=reasoning.
- Re-anchor the tests to assert against the real render functions + the correct attribute.
## Release v0.51.247 — Release HO (stage-q19)
Backend correctness fix.
### Fixed
| Issue | Author | Fix |
|-------|--------|-----|
| #3505 | @franksong2702 | **Reasoning effort is coerced to a level the active model/provider actually supports** before each request, instead of being sent verbatim and rejected. `openai-codex` `gpt-5` no longer gets `max` (→ `xhigh`); `o1`/`o3`/`o4` clamp to `low`/`medium`/`high`. Coercion only steps *down* (never escalates); `none`/unset preserved. The capability filter is applied across heuristic / models.dev / Copilot / LM Studio paths. |
This is the narrow, correct fix for the detection gap that #3431 tried to address by removing the chip-visibility gate (which we shelved). The chip-visibility gate is **untouched** (Codex confirmed) — `get_reasoning_status`/`_applyReasoningChip` still hide the chip for unconfirmed models.
### Review fix absorbed (Codex + self-flagged)
The first cut **dropped** a configured effort for *unrecognized* models, because capability detection returns `[]` for both "known-unsupported" and "simply-unknown" (custom providers, aggregator-rewritten ids, new releases) — that's a behavior change vs master (which sent it verbatim) and would silently disable reasoning. Fixed: an **empty** capability set now **preserves** the configured effort (provider stays the final authority; worst case = the same rejected request master already produces, i.e. no regression). Known-bad clamps return *non-empty* filtered sets, so they still degrade correctly. Nathan chose this "preserve-for-unknown" behavior. + regression test.
### Gate
- Full pytest suite: **7548 passed, 0 failed**
- ruff: CLEAN · 48 reasoning tests pass (incl. preserve-for-unknown + codex-clamp + never-escalate)
- Codex (regression): SHIP-ONLY-WITH-FIXES (unknown-model drop) → fixed → **SAFE TO SHIP**
- Verified empirically: gpt-5/codex max→xhigh, o3 max/xhigh→high, unknown high→high (preserved), none/unset preserved

Closes#461
Adds full /reasoning CLI parity to the WebUI slash command system:
- /reasoning show|on → window._showThinking = true; writes display.show_reasoning to config.yaml (same key as CLI); mirrors to settings.json for boot.js
- /reasoning hide|off → same in reverse; re-renders immediately
- /reasoning none|minimal|low|medium|high|xhigh → POST /api/reasoning → writes agent.reasoning_effort to config.yaml; takes effect next turn (matching CLI semantics)
- /reasoning (no args) → GET /api/reasoning → live status toast from config.yaml
- Autocomplete shows all 8 options: show|hide|none|minimal|low|medium|high|xhigh
- Profile-isolated: _get_config_path() is thread-local so per-profile settings never bleed across
- Boot hydration: window._showThinking initialised from settings.json show_thinking on page load
- Inspect.signature guard in streaming.py so older hermes-agent builds don't TypeError
28 new tests, 1708/1708 total passing. Full browser QA on port 8789 with isolated state. CLI/config.yaml sync verified with hermes_constants.parse_reasoning_effort().
