+ * one a systemd unit under its own Unix user. It is not itself a coding CLI, so
+ * there is nothing for `omniroute run` to launch — this is a configure-only
+ * target.
+ *
+ * Unlike the other recipes, 5dive does not read a config file out of $HOME. Its
+ * credentials live in AUTH PROFILES under /var/lib/5dive/auth-profiles/<name>/,
+ * and the supported way to write one is the CLI itself:
+ *
+ *   5dive agent auth set claude --provider=<id> --base-url=<url> \
+ *     --api-key=- --auth-profile=<name> --model=<slug>
+ *
+ * Four value flags, all four load-bearing (verified against 5dive-cli main,
+ * 2026-08-27):
+ *   --provider      `--base-url` is refused without it, rather than accepted
+ *                   and silently dropped. `openai` here is 5dive's BYO id for
+ *                   "a custom Anthropic-compatible endpoint", not a vendor
+ *                   choice — override with --byo-provider.
+ *   --base-url      OmniRoute's Anthropic surface, ROOT url with no /v1.
+ *   --auth-profile  BYO credentials are profile-scoped; required for claude.
+ *   --model         `openai` has no row in 5dive's built-in endpoint catalog,
+ *                   so there are no per-tier model ids to inherit.
+ *
+ * The key is handed over on stdin (`--api-key=-`) so it never reaches argv.
+ *
+ * Two things this recipe cannot do for you, and says so instead of failing
+ * obscurely:
+ *   1. Writing an auth profile is root-only on the 5dive host. We re-exec
+ *      through sudo when we are not root (disable with --no-sudo).
+ *   2. `agent auth set` writes the profile and restarts the agents bound to it,
+ *      but each seat also carries its OWN runtime model pin, and that pin wins
+ *      over the profile's ANTHROPIC_DEFAULT_*_MODEL. Pass --agent <name> (repeatable)
+ *      to pin the seats too; otherwise we print the command for them.

Discovery only — no new fetcher, no quota change, and the Dashboard quota widget stays gated by `USAGE_SUPPORTED_PROVIDERS`. `USAGE_FETCHER_PROVIDERS` moved to a zero-dependency leaf (`open-sse/services/usage/fetcherProviders.ts`) and is re-exported from `services/usage.ts`, keeping the manifest module a light leaf instead of pulling the ~490-module usage dispatcher into the manifest route.

+- **refactor(video bridge):** extract per-video acquisition, whole-result caching, description, and metrics/abort/cleanup out of `VideoBridgeGuardrail.preCall` into a `processVideoPart` seam in a new `videoBridgePipeline.ts`, behind explicit `VideoMediaBrokerPort`, `VideoAudioTranscriptionPort`, and `VideoDrilldownPort` boundaries; `preCall` now only handles request traversal, policy, and response aggregation. The Video tab's FFmpeg/ffprobe runtime status is now an explicit `unknown` / `restricted` / `unavailable` / `available` state instead of a nullable boolean pair, fixing a case where an in-flight or failed probe was mislabeled as "install FFmpeg" ([#11657](https://github.com/diegosouzapw/OmniRoute/issues/11657)).

+- Stop painting every fork PR into `release/**` red: `quality.yml` `Build (advisory)` is skipped (GitHub still reports `continue-on-error` failures as check FAILURE). Hosted `ubuntu-latest` cannot finish `npm run build` on this tree — same class as #11962 taking `build.yml` off the PR rail. `docker-publish.yml` amd64 now runs on the `.113` `omni-build` pool (31 GB / 32 cores, two listeners) with Turbopack, shares the `heavy-build-main` lane with `ci.yml` `Build` so it queues instead of becoming a third heavy, and keeps per-ref concurrency (a merge storm was starting 8 concurrent OOM builds). arm64 stays on `ubuntu-24.04-arm` with webpack — there is no ARM box. Fallback when `USE_VPS_RUNNER` is off: hosted amd64 + webpack (#11976).

+## 5dive agent fleets
+
+[5dive](https://5dive.ai) runs a fleet of long-running coding agents, each one a
+systemd unit under its own Unix user. It is not a coding CLI itself, so there is
+nothing for `omniroute run` to launch — `5dive` is a **configure-only** target.
+
+```bash
+omniroute configure 5dive --model failover-demo --yes
+omniroute setup-5dive --model failover-demo --auth-profile omniroute --agent worker1
+```
+
+Both forms write one 5dive **auth profile**, and every `claude` seat bound to that
+profile then talks to OmniRoute. Three things are specific to this target:
+
+- **It runs on the fleet host, as root.** 5dive's verbs act on local systemd units
+  and a root-owned state dir; there is no remote mode. The recipe re-execs through
+  `sudo` when it is not already root (`--no-sudo` turns that off and prints the
+  command instead).
+- **The endpoint must be `https://` unless it is loopback.** The agent's API key
+  rides that URL on every request, and 5dive refuses a plaintext off-box endpoint.
+  A private LAN address is not an exception.
+- **Each seat's own model pin outranks the profile.** The profile carries
+  `ANTHROPIC_DEFAULT_{OPUS,SONNET,HAIKU}_MODEL`, but a seat still pinned to a stock
+  model id fails its first turn with _"There's an issue with the selected model"_.
+  Pass `--agent <name>` (repeatable) to pin the seats as well; the recipe prints the
+  command when you do not.
+
+The API key is handed to 5dive on **stdin** (`--api-key=-`), so it never appears in
+`ps` output.
+
+Pointing the profile at an OmniRoute **combo** rather than a single model is what
+gets the fleet provider failover: when the primary endpoint went hard-down mid-turn
+in the run recorded on
+[#11578](https://github.com/diegosouzapw/OmniRoute/issues/11578), the agent finished
+its remaining steps on the fallback and never surfaced the outage.

+Existing clients remain unchanged because acquire, renew, release, and waiting responses retain

+`USAGE_SUPPORTED_PROVIDERS`. The source of truth is `USAGE_FETCHER_PROVIDERS` in
+`open-sse/services/usage/fetcherProviders.ts`.

+> `hidePaidModels`/`hideAutoCombos` (`src/lib/db/settings.ts`) for operators who want a curated

+
+## Why this exists
+
+`hidePaidModels` answers "is this model free?" and `hideAutoCombos` answers "should `auto/*`
+virtual ids be advertised at all?" — neither lets an operator curate an arbitrary subset of
+models (e.g. presenting exactly the models a given Claude Code / OpenCode client should see,
+independent of pricing). #11481 adds that as two independent, opt-in string-array settings.
+
+## Settings
+
+| Key                          | Type       | Default | Meaning                                                          |
+| ----------------------------- | ---------- | ------- | ----------------------------------------------------------------- |
+| `modelVisibilityDenylist`     | `string[]` | `[]`    | Entries matching a candidate hide it from the catalog/candidate pool. |
+| `modelVisibilityAllowlist`    | `string[]` | `[]`    | When non-empty, ONLY entries matching a candidate stay exposed.   |
+
+Both accept up to 500 entries of up to 200 characters each (Zod-validated in
+`src/shared/validation/settingsSchemas.ts`). An entry is either:
+
+- an exact catalog id — `"gpt-4o"` (bare model id) or `"openai/gpt-4o"` (provider-prefixed), or
+- a glob pattern using `*`/`?` — e.g. `"openai/gpt-4*"` or `"anthropic/*"` — resolved via the
+  same shared `globToRegex()` matcher (`src/shared/utils/globPattern.ts`) already used by
+  `ModelRoutingSection`'s per-model combo mappings and `freeModels.ts::matchesOnlyPaidModels`.
+
+Precedence: the denylist is checked first (a denied entry is always hidden, even if it also
+matches the allowlist); when the allowlist is non-empty, only entries it matches survive.
+
+## Two chokepoints, not one
+
+The lesson from #6512 (a `hidePaidModels`-only catalog filter still let `auto/*` route to a
+paid model, since the combo candidate pool was built independently) applies identically here.
+The matching predicate `isModelExposureAllowed()` (`src/shared/utils/modelExposureList.ts`) is
+called from BOTH:
+
+- `src/app/api/v1/models/catalog.ts` — the `/v1/models` listing itself, at the same 5 per-source
+  chokepoints `shouldHidePaid()` already gates (static `PROVIDER_MODELS`, synced provider rows,
+  custom rows, alias-backed rows, managed-fallback rows).
+- `open-sse/services/autoCombo/modelExposureFilter.ts::filterModelExposureCandidates()` — called
+  from `virtualFactory.ts::buildPreparedPool`, immediately after the equivalent
+  `filterPaidOnlyCandidates()` call, so a denied model can never be selected into an `auto/*`
+  candidate pool either.
+
+## What is NOT filtered
+
+Mirrors `hideAutoCombos`'s existing behaviour: a model id sent **explicitly** (not via `auto/*`,
+and not discovered through the catalog listing) is never blocked at dispatch — only
+advertisement/candidate-pool membership is filtered. This is independent of `hidePaidModels`;
+an operator may want a curated set for reasons that have nothing to do with cost, so both
+settings compose as independent AND-ed filters, same as the existing multi-flag composition in
+`catalog.ts`.
+
+Settings export (`GET /api/settings/export-json`) includes both arrays verbatim, like any other
+settings field — unlike `hidePaidModels`'s combo-step export filter, there is no re-hydration
+risk here: a denied id embedded in an exported combo step is the operator's own explicit routing
+choice, not something the export boundary needs to strip.

+// Preflight gate: every package listed in `serverExternalPackages` must be

+//
+// Why this gate exists
+// --------------------
+// npm 11 (bundled with Node 24+) refuses to run install scripts for OPTIONAL
+// dependencies unless they are approved. `better-sqlite3` is an
+// optionalDependency whose install script compiles a native addon, so npm skips
+// it, removes it from the tree, and still exits 0. Nothing in the install output
+// says the package is gone.
+//
+// The build then dies several minutes later with:
+//
+//     Error: Module not found: Can't resolve 'better-sqlite3'
+//
+// which reads like a code error rather than an install one. `serverExternalPackages`
+// does not save it: Turbopack has to RESOLVE a request before it can decide to
+// externalise it, so an absent package is a hard build failure, not a no-op.
+//
+// This check turns that four-minute mystery into a one-second message naming the
+// package and the fix. It only considers packages that are BOTH externalised and
+// declared optional — a required dependency that is missing means `npm install`
+// never ran, which every other part of the build already reports clearly.
+//
+// Escape hatch: OMNIROUTE_SKIP_NATIVE_DEP_CHECK=1 (for exotic vendored trees).
+//

+ * observations already collected by calling a real model against fixtures materialized
+ * from src/lib/guardrails/videoBridgePromotionFixtures.ts, it aggregates medians/p95

+ * (videoBridgePromotionComparison.ts), evaluates both promotion verdicts
+ * (videoBridgePromotionEvaluator.ts), and prints a report that persists metrics + response
+ * DIGESTS only (videoBridgePromotionDigest.ts) — never raw media or raw model responses.
+ *
+ * It does not call any model itself and ships no fabricated data: without a real
+ * observations file it always reports HOLD. Collecting real observations requires a live
+ * model endpoint and the deterministic fixtures this repo can only describe, not execute —
+ * see the PR's "Pending live validation" section for the exact commands to run on

 - **`core.ts`** — `getDbInstance()` returns singleton `better-sqlite3` with WAL journaling. Exports `rowToCamel()` (snake_case → camelCase), `encryptConnectionFields()` for provider credentials at rest. `SCHEMA_SQL` defines **17 base tables** (verify: `grep -c "CREATE TABLE" src/lib/db/core.ts` minus 1 for `_omniroute_migrations`).
 - **`migrationRunner.ts`** — Applies versioned SQL files from `db/migrations/` inside transactions. Tracks applied migrations in `_omniroute_migrations`. Each migration is idempotent.
 - **`db/migrations/`** — 148 SQL files (`001_initial_schema.sql` → `153_radar_local_model_state.sql`; numbering has intentional gaps). Each runs in a transaction, never fails partially.
-- **`localDb.ts`** — Re-export layer only. Never add logic here.

 ## Adding a New Domain Module
 
 1. Create `src/lib/db/[module].ts` with CRUD functions
-2. Export from `src/lib/localDb.ts` (add re-export)
-3. If new tables: create migration in `db/migrations/NNN_[description].sql`

 ## Anti-Patterns
 
 - Raw SQL in routes — always use domain module functions
 - Direct `prepare()` statements outside `db/` — breaks modularity
-- Adding logic to `localDb.ts` — re-export layer only
 - Barrel-importing from `localDb.ts` — import specific modules instead
 - Skipping migrations for schema changes — all changes go through `db/migrations/`

+//   - preview/standard/detail multiresolution variants, resampled on read (never stored
+//     more than once, so producing stays "zero overhead" beyond the opt-in call itself);
+//   - response pagination capped at 8 frames and a bounded response-byte budget;
+//   - a small handle registry with its own TTL/quota, cleaned up alongside the cache.

+// Video Bridge pipeline seam (#11657): the per-video acquisition, sampling,
+// dedup, transcript fusion, result-cache, and metrics/abort/cleanup logic that
+// used to live inline inside `VideoBridgeGuardrail.preCall` (videoBridge.ts).
+//
+// `preCall` stays responsible for request traversal, policy (capability
+// checks, analysis-mode resolution), aggregation across parts, and building
+// the response payload/metadata. Everything about processing ONE video part —
+// including its own AbortController/timeout lifecycle — lives here behind
+// `processVideoPart`, so preCall's loop body is just "call it, fold the
+// result into the running totals."
+//
+// Explicit ports (durable boundaries the ticket asks for):
+//  - `VideoMediaBrokerPort`  — acquiring video bytes and extracting sampled
+//    frames (the `/api/modality-bridge/video/extract` broker boundary; see
+//    videoBridgeBrokerClient.ts and videoBridgeHelpers.ts::loadVideoPartBytes).
+//  - `VideoAudioTranscriptionPort` — the seam that fuses a caller-declared
+//    `audioTranscript` with the sampled visual frame captions
+//    (videoBridgeHelpers.ts::describeVideoPart already does the fusion
+//    internally; this port names that boundary explicitly and is where a
+//    real audio-transcription backend would be substituted).
+//  - `VideoDrilldownPort` — the frame-zoom persistence boundary
+//    (videoBridgeDrilldown.ts::VideoDrilldownCache.put). NOT wired into
+//    `processVideoPart` yet: today only the separate
+//    `/api/modality-bridge/video/drilldown` route writes drill-down entries.
+//    The type lives here so a future extraction step can seed drill-down
+//    candidates from a processed part without re-deriving the port shape.

+ * @file videoBridgePromotionEvaluator.ts
+ * @description Pure FU-07/FU-09 promotion-verdict evaluation for the Video Bridge
+ * promotion-evidence run (#11656). Each `evaluateFuXxPromotion` function takes the
+ * aggregated metrics (see videoBridgePromotionAggregator.ts) for one (case, model) pair
+ * and returns exactly one of `"experimental" | "eligible" | "hold"` by applying the
+ * ticket's frozen numeric thresholds. Both functions are pure (no I/O, no clock reads) so
+ * identical input always yields an identical verdict — the mechanism behind #11656's "two
+ * consecutive runs produce the same eligible verdict" requirement.
+ *
+ * Status model (not fully specified by the ticket beyond "missing usage remains HOLD" —
+ * documented explicitly here since the PR that introduces this file calls it out as a
+ * design decision):
+ *   - HOLD: a hard blocker fired — missing token usage, any critical-fact loss, or any
+ *     failed security case (FU-07) / any critical-or-security loss (FU-09). These are
+ *     safety/data-integrity gates, never partially satisfied.
+ *   - EXPERIMENTAL: no hard blocker fired, but at least one soft numeric threshold (quality
+ *     retention, p95 ratio, material gain, absolute quality, latency/token reduction) was
+ *     not met — promising, not yet promotable.
+ *   - ELIGIBLE: no hard blocker AND every soft threshold met.

+ * is read-only transparency (#7819 Level 1): a locked/cooled-down candidate
+ * must still be listed, decorated with `reachable:false` and an accurate
+ * reason (`modelLocked`), not deleted from the pool before the inspector
+ * ever sees it.
+ *
+ * Root cause (measured by community contributor ntdat812, ratified by the
+ * owner 2026-08-22): `prepareVirtualAutoComboInputs` unconditionally ran
+ * `filterResilienceBlockedCandidates` before the listing endpoint decorated
+ * the pool, so `modelLocked`/`reachable:false` were dead fields — the rows
+ * they would apply to were already gone.

+ * `result.response` (non-streaming) or
+ * `wrapResponseWithOAuthSessionRelease(result.response, releaseOAuthSession)`
+ * (streaming) directly, without first calling `withSelectedConnectionHeader()`
+ * — unlike every failure exit in the same function, which does call it.

+ * As a result `X-OmniRoute-Selected-Connection-Id` was absent on every
+ * successful response for a dynamically-selected (unpinned) connection, so
+ * combo.ts's consumers (success-decay, provider cooldown recovery, webhook
+ * attribution, session stickiness, LKGP) fell back to the target's static
+ * `connectionId`, which is empty for provider-level combo targets like

-/**
- * TDD regression tests for the per-connection 429 cascade DB persistence.
- *
- * Bug: before this fix, `applyErrorState` (open-sse/services/accountFallback.ts)
- * marked a connection rate-limited IN-MEMORY ONLY — the cooldown was forgotten
- * when the request ended and `isConnectionRateLimited` (the DB-backed read
- * helper) always returned false for non-Antigravity providers. Result: cascade
- * failures against a multi-key OpenCode-Go setup retried the same exhausted key
- * on the next request and the user saw no "kill for X days" behavior.
- *
- * After the fix:
- *   1. `applyErrorState` with a non-zero cooldown also writes
- *      `provider_connections.rate_limited_until` via
- *      `setConnectionRateLimitUntil` (best-effort, never crashes the request).
- *   2. `resetAccountState` with a DB id clears that column.
- *   3. The localDb re-exports `markConnectionRateLimitedUntil` and
- *      `clearConnectionRateLimit` for direct use by other consumers
- *      (e.g. provider-specific executors).
- *
- * These tests mirror the harness from `antigravity-429-quota-cooldown.test.ts`
- * so they share the same DATA_DIR sandbox and DB reset pattern.

+/**
+ * TDD regression tests for the per-connection 429 cascade DB persistence.
+ *
+ * Bug: before this fix, `applyErrorState` (open-sse/services/accountFallback.ts)
+ * marked a connection rate-limited IN-MEMORY ONLY — the cooldown was forgotten
+ * when the request ended and `isConnectionRateLimited` (the DB-backed read
+ * helper) always returned false for non-Antigravity providers. Result: cascade
+ * failures against a multi-key OpenCode-Go setup retried the same exhausted key
+ * on the next request and the user saw no "kill for X days" behavior.
+ *
+ * After the fix:
+ *   1. `applyErrorState` with a non-zero cooldown also writes
+ *      `provider_connections.rate_limited_until` via
+ *      `setConnectionRateLimitUntil` (best-effort, never crashes the request).
+ *   2. `resetAccountState` with a DB id clears that column.
+ *   3. The localDb re-exports `markConnectionRateLimitedUntil` and
+ *      `clearConnectionRateLimit` for direct use by other consumers
+ *      (e.g. provider-specific executors).
+ *
+ * These tests mirror the harness from `antigravity-429-quota-cooldown.test.ts`
+ * so they share the same DATA_DIR sandbox and DB reset pattern.

+// Regression test for #11825 — the `onStreamComplete` plugin event is emitted

+// emitHook) but never DELIVERED to disk-installed plugins, because the plugin-facing
+// wiring is missing at three layers:
+//   1. src/lib/plugins/manifest.ts   — HooksSchema has no `onStreamComplete` field, so
+//      `hooks.onStreamComplete: true` in plugin.json is silently stripped by Zod.
+//   2. src/lib/plugins/loader.ts     — loadPlugin() never builds an IPC wrapper for it.
+//   3. src/lib/plugins/manager.ts    — activate()'s hardcoded `hookNames` list omits it,
+//      so even a wired handler is never registerHook()'d into the registry.
+// The pre-existing green tests (tests/unit/chatcore-plugin-onresponse.test.ts) call
+// `registerHook("onStreamComplete", ...)` directly — a path real plugins cannot use — so

+// scripts/quality/run-eslint-json.mjs is the script behind `npm run lint:json`,
+// which backs the CI `Lint` job's blocking ESLint pass (.github/workflows/ci.yml
+// step "ESLint (JSON report)"). It builds this exact args array (see
+// scripts/quality/run-eslint-json.mjs lines 31-42):
+//
+//   [".", "--cache", "--cache-location", ".eslintcache",
+//    "--suppressions-location", "config/quality/eslint-suppressions.json",
+//    "--format", "json", "--output-file", outFile, ...extra]
+//
+// and does `process.exit(result.status)` verbatim — i.e. it propagates ESLint's
+// raw exit code, including exit code 2, which ESLint uses specifically for "There
+// are suppressions left that do not occur anymore" (a stale/orphaned suppression
+// entry), REGARDLESS of whether the tree has any real (unsuppressed) lint error.
+//
+// scripts/quality/validate-release-green.mjs already had to fix the identical
+// failure class by adding --pass-on-unpruned-suppressions (PR #7962, issue #7837)
+// — see that script's own comment: "An 'unpruned' suppression means a previously-
+// frozen violation was legitimately fixed ... Without this flag ESLint 9.x exits 2
+// for that reason alone". run-eslint-json.mjs never received the same fix, so the
+// CI `Lint` job goes red whenever a suppression is orphaned by someone genuinely
+// fixing pre-existing debt, even with zero real errors in the tree.
+//
+// This test reproduces run-eslint-json.mjs's EXACT args array (mirrored above,
+// verified against the source at HEAD) against a minimal, isolated ESLint fixture
+// (not OmniRoute's own 10k+ file tree — a cold full-tree lint costs 14-60min per
