Theme of the batch

Twelve small, well-scoped contributor fixes that mop up correctness regressions, polish, and i18n gaps across run-state consistency (chat-start adapter parity, journal recovery on populated-core sync, context-window metadata refresh, model cache fingerprint, active-session spinner reconcile), live-streaming UX (compact thinking card dedup, stream-fade drain cap, thinking copy button), cron + gateway plumbing (manual cron delivery parity, email gateway source labeling), and stale-help-text cleanup (/theme i18n in 5 locales, Compact tool activity preference description).

Opus advisor sanity check

Decision: SHIP

12 small, well-scoped contributor fixes with consistent test coverage; cross-file wiring reads consistently; defensive fallbacks on the cron and model-metadata paths preserve graceful degradation against older hermes-agent builds; no assertion weakening; no streaming-path risk. Two minor robustness notes (SILENT casing follow-up, substring-match locality) are follow-up candidates, not stage-fix gates.

Opus specifically verified:

• routes.py 3-PR convergence: Preserve chat-start response shape for RuntimeAdapter path #2438 trim local to runtime_adapter_enabled() branch; Refresh session context metadata on model changes #2444 helper at line 1665 vs fix: deliver manual cron run results #2452 cron at line 754 — different functions, no shared state, no duplicate defs.
• fix: deliver manual cron run results #2452 cron delivery: defensive getattr + TypeError shim on mark_job_run degrades gracefully against older hermes-agent cron modules.
• fix: clear stale active session sidebar spinner #2455 reconcile cross-script _sendInProgress lookup: classic <script defer> globals are reachable; typeof !== 'undefined' guard is belt-and-braces.
• Recover journal output after core transcript sync #2439 dedupe: _find_existing_assistant_for_journal_content requires len(candidate) >= 24 for substring fallback; _run_journal_has_visible_output gates pending-user recovery.
• Test changes: every existing-test edit is either doc-string rewording or structural refactor following a helper extraction (kwargs preserved, except TypeError shim retained). No assertion weakening.

Not in this batch (intentionally)

• fix: add WebUI memory-provider session lifecycle for batch-extraction providers #2461 (@starship-s, 768 LOC) — WebUI memory-provider session lifecycle for batch-extraction providers. Substantial new module (api/session_lifecycle.py) plus seam edits in api/streaming.py / api/routes.py / api/config.py / server.py. Deferred to a focused independent-review pass on its own; not eligible for batch slot with 1-3 file fixes.
• feat(webui): add Custom Relays CRUD for OpenAI-compatible 中转 endpoints #2298 (@bib-toread, 966 LOC) — Custom Relays CRUD. Held on contributor fix-cycle: 3 CI failures (Russian/Spanish locale gaps + native confirm() call) flagged 2 days ago, no contributor response yet.
• feat(streaming): wake the agent server-side when a notify_on_complete background task finishes while the WebUI tab/session is idle #2242 (@Isla-Liu, draft, CONFLICTING) — process_complete SSE event. Maintainer signal posted yesterday with rebase + reposition instructions; contributor turn.
• Swipe actions for touch devices & session list improvements #2252 (@dobby-d-elf, ux + hold) — Mobile session-list swipe actions. Aron actively iterating with contributor on visual polish today; NOT-STUCK.
• [codex] Fix workspace-prefixed user turn leakage #2145, [codex] Track update checks by release tags #2146 (@swftwolfzyq) — Just flipped from draft to ready today after maintainer ultimatum; hold removed, queued for independent review on next batch.
