docs(changelog): aggregate the ten v3.8.50 fragments into CHANGELOG.md (#11683)

The fragments were written during the pre-flight but the aggregation step was
left uncommitted, so the release PR merged with the ten files still loose in
changelog.d/ and CHANGELOG.md missing their entries. Tagging from that state
would have published v3.8.50 without documenting the discarded upstream call
burning quota (#11552), the configured search connection being silently ignored
(#11524), the /v1/models SWR refresh blocking its own stale response (#11551),
the combo builder's manual model entry (dark since #8285) and the local CLI's
health view (dark since #11040) — the entries an operator actually reads.

Runs the aggregator on top of main and deletes the fragments in the same commit,
per changelog.d/README.md.

 - **fix(models):** health-check-excluded models are hidden from the `/v1/models` catalog ([#10026](https://github.com/diegosouzapw/OmniRoute/issues/10026) — thanks @ritheshcn25)

 - **fix(mcp):** CLI MCP call protocol issues were resolved ([#10960](https://github.com/diegosouzapw/OmniRoute/issues/10960) — thanks @YunyunZhai)
+- **fix(dashboard):** expert mode in the Combo Builder can type a provider/model pair by hand again ([#8875](https://github.com/diegosouzapw/OmniRoute/pull/8875)) — [#8285](https://github.com/diegosouzapw/OmniRoute/pull/8285) (global model search) replaced the "Manual model" block positionally with the new search panel, removing the only way to enter a model that is not in the catalog. The state and handlers behind it survived as dead code, so neither typecheck nor lint noticed the loss. The block is restored above the search panel, unchanged from its pre-#8285 form, and guarded by `tests/e2e/combos-flow.spec.ts` ("expert mode shows a single-page combo form with manual model entry").
+- **fix(sse):** a combo step pinned to an explicit connection (or a request pinned with `x-omniroute-connection`) is honored on fallback instead of silently rotating to a sibling account ([#8875](https://github.com/diegosouzapw/OmniRoute/pull/8875)) — the generic account-fallback branch excluded the pinned connection after an upstream failure and re-selected another account of the same provider, so a priority combo repeating one provider/model with two different fixed accounts ran **both** attempts under the first step; the second step and its own pin never executed, and per-step attribution (`comboStepId` / `comboExecutionKey`) was wrong. Rotation is now gated on there being no forced connection, matching the stream-readiness, pre-response-timeout and account-semaphore branches. Cooldown recording is unchanged, and unpinned selection still skips burned connections.
+- **fix(cli):** the local CLI sees the full `/api/monitoring/health` payload again — `version` included — restoring the `check:pack-boot` release gate. [#11040](https://github.com/diegosouzapw/OmniRoute/pull/11040) reduced that route to a liveness-only view for non-management callers (GHSA-mvf8-qc78-5mxm), but the route is classified PUBLIC and `runAuthzPipeline` strips the machine-token header for every route class — so the PUBLIC policy stamped `anonymous` and the loopback CLI could never be recognized as a management principal. The PUBLIC policy now stamps the same loopback-gated `local-cli-token` subject the MANAGEMENT policy already did; anonymous callers still get liveness only.
+- **fix(search):** a configured search connection (Serper, Brave, Tavily…) is now used instead of being silently passed over for the free `duckduckgo-free` fallback ([#11524](https://github.com/diegosouzapw/OmniRoute/issues/11524)) — when no provider was named explicitly and the cheapest auto-selected one had no credentials, the last-resort loop ran first and `duckduckgo-free` (cost 0, no auth) always won it with empty credentials. On `/v1/responses` the call then returned `success: true` with **zero results**, so web search looked healthy while the paid connection the operator had set up was never called. Credentialed regular providers are now swept before the last-resort loop, and fallback-only providers can no longer outrank a configured one on price.
+- **fix(api):** `/v1/models` no longer blocks the stale response while it rebuilds the catalog ([#11551](https://github.com/diegosouzapw/OmniRoute/issues/11551)) — the route has been passing a `scheduleBackgroundRefresh` option since #10198, but the parameter had already been removed from `getUnifiedModelsResponse()`, so the object was silently dropped and the stale-while-revalidate rebuild still ran on a `setTimeout(..., 0)`. The builder is essentially synchronous under the App Router, so it pinned the event loop **before** the cached response was flushed — the [#8728](https://github.com/diegosouzapw/OmniRoute/pull/8728) guarantee did not actually exist for operators with large catalogs. `catalogCache` now schedules through `after()` (with a macrotask fallback outside a request scope) and the option is threaded end to end. The extra argument was invisible to CI because `typecheck:core` is a curated allowlist and `next.config.mjs` sets `ignoreBuildErrors: true`.
+- **fix(sse):** a universal handoff whose summary comes back unusable is no longer regenerated on every single model switch, which was burning paid quota on upstream calls whose answers were thrown away ([#11552](https://github.com/diegosouzapw/OmniRoute/issues/11552)) — nothing is persisted when the summary does not parse, so the next switch in the same session re-issued the same full-history summarization request and discarded it again, forever. With a switch-heavy combo strategy (weighted, random, round-robin, p2c) that landed on a large share of requests: measured at n=200, roughly **one request in four carried an extra discarded upstream call**, and that traffic skewed a weighted 70/30 combo to an observed 0.895 share for one provider even though the share actually delivered to the client was a correct 0.70. There is now an exponential back-off per (session, combo) — 5 min up to 1 h, cleared on the first successful handoff, capped at 500 tracked keys. A transient upstream failure is deliberately **not** tracked, so it still retries immediately. After the fix: 201 upstream calls for 200 requests, and the measured share matches the delivered one.

 - **chore(repo):** repository hygiene — the self-referential `_tasks` symlink was untracked and `.gitignore` anchored so a `_tasks` symlink can never be tracked again, `.source/dynamic.ts`, `.source`, `/output/` and the Playwright CLI artifact directory were ignored, an initial `.cbmignore` was added for codebase-memory indexing, unused `.source/dynamic.ts` and `source.config.mjs` files were removed, the stray unresolved conflict marker in `ENVIRONMENT.md` was cleaned up, and the Open Collective sponsorship link was removed from the README
 - **chore(release):** localized `llm.txt` mirrors and the v3.8.50 base quality docs were synchronized, and the 363 `changelog.d` fragments were aggregated into this section
+- **fix(ci):** the pack-artifact provenance gate now checks the branch under test instead of `origin/main` ([#8875](https://github.com/diegosouzapw/OmniRoute/pull/8875)) — the guard added for [#10427](https://github.com/diegosouzapw/OmniRoute/issues/10427) is correct at publish time (that workflow runs on `main`), but in a `pull_request` context the head is by construction not an ancestor of `main` and the shallow checkout never fetches it, so the probe always answered false and the job failed 100% of the time. It became visible only once it stopped being cancelled behind Build. Pre-merge it resolves the ref from `refs/pull/<N>/head`, which exists on origin even for fork PRs.
+- **test(dashboard):** the proxy-registry e2e smoke flow opens the toolbar's "More actions" overflow menu before clicking bulk assign ([#8875](https://github.com/diegosouzapw/OmniRoute/pull/8875)) — [#9870](https://github.com/diegosouzapw/OmniRoute/pull/9870) moved the action into that menu, which only renders its items while open, so the locator never resolved and the test burned its full 180 s budget. Every existing assertion is unchanged.
+- **test(api):** the `/v1/models` e2e check accepts the auth gate introduced by [#9320](https://github.com/diegosouzapw/OmniRoute/pull/9320) ([#8875](https://github.com/diegosouzapw/OmniRoute/pull/8875)) — the catalog now requires auth whenever management auth is configured, and the harness boots with `INITIAL_PASSWORD` set, so the endpoint had been answering 401 since 2026-08-04 and the check was red the whole time, hidden behind a cancelled job. It now mirrors the sibling `/api/providers` check: assert the catalog shape when the catalog is served, otherwise pin the gate by status **and** error type so an unrelated 401 cannot pass for the deliberate one.
+- **chore(quality):** refreshed the combos-page ESLint suppressions after the manual-model restore ([#8875](https://github.com/diegosouzapw/OmniRoute/pull/8875)) — three `no-unused-vars` suppressions existed only because #8285 had deleted the JSX consuming that state; with the block back they are live again, and a stale suppression makes ESLint exit 2, which is what actually turned the Lint job red. The 7 `react-hooks/set-state-in-effect` plus 1 `react-hooks/immutability` errors in the same file are pre-existing (reproducible on the file's `091e2ba4da` content) and surfaced only because touching the file evicted it from the restored `.eslintcache`; they are frozen here and tracked separately rather than refactored mid-release.

+OmniRoute never starts transcription from this metadata: validated cues are

-subtitle stream. FFprobe may offer only `mov_text`, `subrip`, or `webvtt` text
-streams; the explicit default stream is tried first, then stream index order,
-with at most two attempts. FFmpeg receives fixed argv, the `file`-only protocol
-whitelist, and converts the selected local stream to bounded UTF-8 WebVTT.
-All subtitle stream attempts share one aggregate 10-second ceiling, further
-bounded by the caller timeout and enclosing request abort signal, and each
-attempt has a 256 KiB output cap. Malformed WebVTT, invalid UTF-8, unsupported
-codecs, missing/empty tracks, and subtitle timeouts fail open to the already
-extracted video frames; request abort still propagates and cleanup still runs.
-Clean absence is cacheable, but a bounded decoder, process, or timeout failure is
-classified as transient and the whole-video result is not cached, so a later identical
-request retries embedded-text extraction instead of reusing a degraded result.

-This embedded-caption capability is deliberately format-limited, not universal.
-It is attempted only after the container has passed the Video runtime's exact
-format allowlist: `3g2`, `3gp`, `avi`, `flac`, `flv`, `m4a`, `matroska`, `mj2`,

-playable video stream plus one of the three supported text-subtitle codecs.

-Client and embedded tracks accept at most 256 cues, 4 KiB of UTF-8 text per
-cue, and 64 KiB of cue text per track. The final combined timeline retains at
-most 256 cues and 64 KiB of canonical cue text. The inherited audio-fusion
-seam is intentionally stricter: `audioTranscript` becomes a partial-invalid
-audio branch above 128 observations or 32 KiB, without discarding the visual
-result. Text is NFC-normalized; malformed Unicode (replacement characters or
-unpaired surrogates) is rejected, C0/C1 controls are rejected or normalized,
-and whitespace is collapsed. Timestamps are millisecond-quantized where
-representable, then clamped to the raw probed duration; a valid sub-millisecond
-cue that would collapse expands outward within that bound. Broker-derived
-WebVTT endpoints are also clamped before this shared normalization. When a
-focus window is present, every client, embedded, and audio track is filtered
-for positive overlap and clamped to that window before reconciliation; scoped
-embedded count/fingerprint metadata covers only the retained embedded cues.
-Cross-source duplicates require both a canonical text match (NFKC,
-case-insensitive, punctuation/symbol-insensitive, whitespace-collapsed) and a
-positive time overlap. If that canonical identity is empty, as for symbol-only
-cues, exact normalized text is used instead so distinct observations such as
-music and bell symbols are not collapsed. Repeated text at disjoint times remains separate.
-Duplicate priority is deterministic: `client` > `embedded` > `audio-bridge`;
-the canonical cue retains every contributing source, the aggregate union
-interval, and highest confidence, plus source-specific contribution intervals
-and confidence values. Cue text is JSON-quoted and literal square brackets are
-escaped as `\u005b`/`\u005d` inside the stable untrusted transcript delimiter,
-so cue punctuation, quotes, or line breaks cannot create a literal delimiter.
-This structural quoting does not make media text trusted or prevent semantic
-prompt injection; the outer untrusted-media instruction remains authoritative.
-
-An advanced caller may provide an explicit `audioTranscript` track for the
-same video. Those cues must use the distinct caller-declared `audio-bridge`
-lane; the request cannot relabel them as client or embedded text, and this lane
-does not receive the server-derived trust assigned only to `embedded`. The fusion seam
-runs visual and audio observations under one deadline and abort signal, reconciles
-overlapping transcript duplicates with the policy above, and reports a partial

-A successful bridge rewrite carries only the exact

-descriptions as out-of-band trust metadata; the raw cue text is not present in
-those identities. Log redaction verifies each exact generated segment, including
-inside a provider string that concatenates translated text blocks, so adding a
-real video carrier cannot make an adjacent delimiter-shaped caller string trusted
-or omitted while the bounded scan stays within 128 description prefixes and 512
-candidate hashes. Above either CPU-work cap, the retained copy fails closed to one
-omission marker; the live request remains unchanged. Structured traversal uses a
-separate security depth of 32 and an aggregate 10,000-entry budget, both above the
-ordinary log-depth policy; crossing either bound also fails closed to one marker.
-Sensitive requests also omit provider/client response and error bodies and
-suppress detailed and active stream-chunk capture even when pipeline logging is
-disabled. Retained stream-controller and transform callback diagnostics use the
-same omission marker while the real error remains available to client handling and
-fallback classification. A plain request that merely spells a Video-description or
-transcript delimiter does not acquire those logging privileges. Because the
-retained call artifact no longer contains replay-complete media context, Responses
