Release v3.8.28 (#4053)

* chore(release): open v3.8.28 development cycle

* fix(ws): warm SSE auth import on LiveWS startup; relocate boot test to integration (#4063)

The live dashboard WebSocket sidecar lazily import()-ed the SSE auth module
inside the connection handler, only on the API-key path. That cold import pulls
in hundreds of transitive modules and takes ~7s under tsx, blocking the
single-threaded event loop. The first API-key WebSocket connection therefore
stalled the loop long enough that any connection arriving in that window — e.g.
a same-origin cookie client — could not complete its handshake and timed out.

This was deterministic, not an "env flake": the boot test fires an API-key
connection immediately followed by a cookie connection, so the cookie connection
always raced the cold import and timed out (reproduced 3/3 locally and red on
every CI run; proven via instrumented probes — reversing the order or warming
the module first makes both connections open in ~20ms).

Fix:
- Memoize the auth-module import and warm it once at startup (before listen), so
  connection handling never pays the cold-import cost. Real improvement: the
  first API-key client no longer stalls the event loop for concurrent clients.
- Relocate the boot test from tests/unit/cli to tests/integration. It spawns a
  real subprocess + WS server + SQLite (~9-11s); under the unit suite's
  --test-concurrency=20 it contended for CPU and destabilized the shard. The
  serial integration runner is its correct home; it still guards #4004's
  cookie-parse fix on every PR via the integration CI job.
- Bump the test's startup/overall timeouts to absorb the eager auth warm.

Makes `npm run test:unit` deterministically green (the only remaining unit red).

Validated: relocated test 3/3 green via the integration runner (was 3/3 red);
typecheck:core + eslint clean; confirmed it no longer matches the test:unit glob
and does match tests/integration/*.test.ts.

* fix(ws): start LiveWS sidecar with cwd at package root (#4055) (#4064)

* chore(deps): bump ossf/scorecard-action from 2.4.0 to 2.4.3 (#4045)

Integrado em release/v3.8.28. Patch de SHA do ossf/scorecard-action (2.4.0→2.4.3), mantém SHA-pin. Reds de CI são exclusivamente os shards flaky pré-existentes branch-wide (Unit 7/8, Integration, Coverage 7/8, Node 1/2) — não relacionados ao bump (PR deps-only).

* deps: bump electron from 42.4.0 to 42.4.1 in /electron (#4049)

Integrado em release/v3.8.28. Patch do electron (42.4.0→42.4.1). Reds de CI: shards flaky pré-existentes + PR Test Policy = falso-positivo (mudança deps-only sob electron/ não comporta teste de código) + Node 26(2/2) sem step (flake/infra). Precedente #3913/#3914 (electron dependabot mergeado nessas condições).

* fix(auto): resolve built-in auto catalog combos (#4058)

Integrado em release/v3.8.28. Resolve os IDs de catálogo `auto/*` built-in (combos virtuais) — corrige o 400 "No auto combos configured" em auto/best-coding etc. Ajuste de review: os mapas AUTO_TEMPLATE_VARIANTS/VALID_AUTO_VARIANTS duplicados em chat.ts e chatHelpers.ts foram extraídos para open-sse/services/autoCombo/builtinCatalog.ts (DRY), devolvendo chatHelpers.ts <800 LOC; baseline de chat.ts rebaselinado 1432→1458 (lógica nova). Fast QG + semgrep + dast verdes; 22/22 testes.

* chore(docs): update Discord invite link to a non-expiring one (#4067)

* chore(deps): freeze @huggingface/transformers in dependabot (hard-pin) (#4066)

Integrado em release/v3.8.28. Congela @huggingface/transformers no dependabot (pin exato 3.5.2, load-bearing p/ LLMLingua + memory embeddings, VPS-validado #4014). Fast QG + semgrep + dast verdes.

* ci(quality): flip TIA impacted-unit-tests gate from advisory to blocking (#4069)

The pre-existing release unit test-debt that kept the TIA "Impacted unit tests"
step advisory has been cleared:
- #4030 restored 16 lossless Zod/registry reds (from the oyi77 modularize refactors).
- #4063 fixed the last red — the LiveWS boot test — which was a real deterministic
  event-loop stall in the WS sidecar (cold ~7s lazy auth import racing a second
  connection), not an env flake; fixed (warm the import at startup) and relocated to
  the integration suite.

A full workflow_dispatch ci.yml run on release/v3.8.28 then showed all 8 Unit Tests
shards green. The remaining Integration Tests / Quality Ratchet reds are pre-existing
and unrelated (combo/resilience env-flakes; eslint/i18n baseline drift).

Removing continue-on-error makes PR->release block on unit-test regressions in the
TIA-selected impacted set (fail-safe still runs the full unit suite on hub/unmapped
changes). typecheck:core was already blocking. Closes the fast-gates "no tests on
PR->release" hole (Quality Gate v2 / Fase 9, P2).

* test(infra): isolate DATA_DIR per test process; raise Stryker concurrency 1→4 (#4078)

* test(infra): isolate DATA_DIR per test process; raise Stryker concurrency 1→4

Every test process resolved DATA_DIR to the same default (~/.omniroute) when the env
var was unset (src/lib/dataPaths.ts::resolveDataDir), so concurrent test files opened
the SAME on-disk storage.sqlite. node:test spawns a process per file and Stryker spawns
one per sandbox, so this shared file caused cross-file state races:
- SQLite lock contention that hung `npm run test:unit` under high --test-concurrency
  (the ~95-min local hang), and
- the non-deterministic baseline that forced stryker.conf.json to concurrency: 1, which
  in turn could not finish the ~15k-mutant run inside the nightly timeout (the cancelled
  2026-06-16/17 nightly-mutation runs) — blocking Quality Gate v2 / Fase 9 Onda 2.

open-sse/utils/setupPolyfill.ts could NOT host the fix: it is imported by production
(bin/omniroute.mjs, proxyFetch.ts, proxyDispatcher.ts), where redirecting DATA_DIR would
point the live SQLite DB at a throwaway temp dir. So this adds a TEST-ONLY
tests/_setup/isolateDataDir.ts that gives each process its own temp DATA_DIR when none is
set (tests that set DATA_DIR explicitly still win), wired via --import into the test,
mutation and CI invocations.

Verified:
- Stryker dry-run A/B at concurrency=4: FAILS without the isolation import
  (account-fallback-service tap exit 9, a cross-file race) and PASSES with it.
- Full `npm run test:unit` green with isolation (0 fail; a one-off
  chatcore-translation-paths timeout flake did not reproduce and passes 3/3 isolated)
  and noticeably faster — the DB lock contention is gone.
- New tests/unit/isolate-datadir.test.ts guards the contract (unique temp DATA_DIR when
  unset; explicit DATA_DIR respected).

Wired the --import into: package.json (13 test scripts), stryker.conf.json (tap.nodeArgs
+ concurrency 1→4), .github/workflows/quality.yml (TIA step), ci.yml (the 5
unit/coverage/integration commands), and bumped nightly-mutation.yml timeout 120→180 for
the first cold run before the incremental cache is seeded.

* ci(quality): run the TIA gate at CI concurrency (4) to stop oversubscription flakes

The TIA "Impacted unit tests" step (made blocking in #4069) ran its fail-safe via
`npm run test:unit` — concurrency=20, tuned for multi-core dev machines. On a 4-vCPU CI
runner that is 5x oversubscribed, so timing-sensitive tests flake under the load (e.g.
`db-backup-extended` "The database connection is not open", `chatcore-translation-paths`
upstream-timeout). That intermittently fails a blocking gate on legitimate PRs — exactly
what surfaced on the DATA_DIR-isolation PR, whose package.json/workflow changes trip the
__RUN_ALL__ fail-safe.

Run both the impacted set and the fail-safe at --test-concurrency=4, matching the stable
ci.yml unit job. Adds a `test:unit:ci` script (test:unit at concurrency=4). The DATA_DIR
isolation in this PR keeps the parallel run race-free, so the only change here is matching
the runner's core count. Verified locally: db-backup-extended passes 8/8 in isolation
(5 with isolation, 3 without).

* docs(quality-gates): reconcile gate inventory with ci.yml + add ROI rationalization backlog (#4095)

The "authoritative" gate inventory in QUALITY_GATES.md had drifted from ci.yml: it omitted
9 wired gates — `audit:deps`, `check:tracked-artifacts`, `check:lockfile`, `check:licenses`
(lint job), `check:dead-code`, `check:cognitive-complexity`, `check:type-coverage`,
`check:codeql-ratchet` (quality-gate job), and `check:pr-evidence` (pr-test-policy job).
You can't rationalize an inventory you can't trust, so this reconciles it first.

Adds those 9 rows to their job tables and a "Rationalization Backlog (ROI review)" section
capturing the Fase 9 Onda 3 findings: mechanical merge/dedup candidates (CVE scanners
audit:deps↔osv, the two complexity ESLint passes, cycles↔circular-deps, the two /api
anti-hallucination gates, the doubly-run check:docs-sync, check:node-runtime ×11) and the
operator-only flip/drop decisions (typecheck:noimplicit vs the type-coverage ratchet,
test:vitest:ui parked fails, check:secrets frozen FPs, openapi-security-tiers, pr-evidence,
the orphaned semgrep baseline). Also flags the undocumented advisory docs-lint job and the
standalone scanner workflows.

Docs-only — no gate behavior changes. The merges (CI changes) and flips (policy) are
deferred to operator-scoped follow-ups; this PR only makes the map accurate.

Onda 3 (gate ROI-review) Phase 2. Two parts, both low-risk:

1. Remove the standalone `check:docs-sync` from the `lint` job — it already runs in the
   `docs-sync-strict` job (via `check:docs-all`) and the husky pre-commit hook, so the
   `lint`-job copy was a pure duplicate. No coverage lost.

2. Update the Rationalization Backlog in QUALITY_GATES.md with trust-but-verify findings:
   several "obvious" merges/flips from the ROI review turned out to hide debt and are NOT
   clean drop-ins —
   - CVE merge (audit:deps→osv): different semantics (hard high/critical vs regression-ratchet) — keep both.
   - cycles→circular-deps: dpdm reports 91 cycles (can't promote to blocking) and is broader-scope than the green curated check:cycles — keep both.
   - openapi-security-tiers flip: blocked by traffic-inspector routes missing the x-loopback-only annotation.
   - complexity + /api merges: valid but real config/script surgery — deferred.
   - node-runtime ×11: ~10s savings vs a cheap guard — low ROI, skip.

   The remaining flips (typecheck:noimplicit, test:vitest:ui, check:secrets, pr-evidence,
   semgrep) are operator policy decisions, left for the owner.

* fix(dashboard): event-driven fail-open auto-refresh for embedded log views (#4054) (#4103)

The Request Logger gated each auto-refresh tick on a static
document.visibilityState === "visible" read. Hosts that report a permanent
non-"visible" state without ever firing a visibilitychange event (Docker
dashboard wrappers, embedded/proxied webviews) froze auto-refresh entirely —
only the manual Refresh button worked, a regression from 3.8.24's unconditional
polling.

The pause is now event-driven and fail-open: visibleRef starts true and is only
flipped to false on a real visibilitychange → hidden transition, so a host that
never signals a genuine background transition keeps polling, while normal
browser tabs still pause when actually backgrounded.

Regression test reproduces the misreporting-host case (RED) and the perf guard
is re-encoded under the event-driven semantics.

* fix(docker): raise build-stage Node heap to stop production-build OOM (#4076) (#4104)

The Docker builder stage ran `npm run build` with V8's default heap ceiling
(~2 GB). After #4052 forced the heavier webpack engine (Turbopack panics on this
Next.js version), the production optimization pass exceeded that ceiling and the
build died with "FATAL ERROR: ... JavaScript heap out of memory" at
[builder] npm run build.

The builder stage now sets NODE_OPTIONS=--max-old-space-size (default 4096 MB,
overridable via --build-arg OMNIROUTE_BUILD_MEMORY_MB) before the build; the
value propagates to the spawned next build (resolveNextBuildEnv spreads
process.env). Build-only — the runtime heap on the runner stage is unchanged,
and CI/local builds (which invoke npm run build directly) are unaffected.

Regression guard: tests/unit/dockerfile-build-heap-4076.test.ts asserts the
builder stage sets the heap ceiling, before npm run build, at >= 4096 MB.

- Build the complete [3.8.28] CHANGELOG section (55 bullets) covering every
  commit since v3.8.27, grouped by type with PR back-references and human
  contributor attribution (artickc's memory-leak/perf cluster, OrcaRouter,
  Wafer AI, MITM gaps, etc.); move the OrcaRouter bullet out of [Unreleased].
- Inject the EN [3.8.28] section into all 41 i18n CHANGELOG mirrors (parity).
- Reconcile the env/docs contract: document MITM_IDLE_TIMEOUT_MS + MITM_VERBOSE
  in .env.example and ENVIRONMENT.md; allowlist the framework-internal TURBOPACK
  and the Claude Code ANTHROPIC_AUTH_TOKEN in check-env-doc-sync.
- Fix 3 broken relative links in docs/providers/AGENTROUTER.md (regressed when
  the file was relocated this cycle) so docs-sync-strict passes.

* fix(quality): treat test→test renames as relocations, not deletions

The anti-test-masking gate's subcheck-1 collected deleted AND renamed test
files via `--diff-filter=DR --name-only` and flagged every one as "deleted —
human review required", contradicting its own documented contract ("DELETADOS
ou renomeados-e-NÃO-substituídos"): a rename test→test IS a substitution (the
test moved, coverage preserved). This false-positived on #4063's legitimate
relocation of live-ws-startup.test.ts (unit/cli → integration, asserts 2→2)
and would block every PR that relocates a test — surfacing only at release-day
because the Fast QG (PR→release) doesn't run test-masking.

The gate now parses `--name-status -M`: true deletions and test→non-test
renames still flag; a test→test rename is run through the assert-reduction
check across the move, so a clean relocation passes while gutting-via-rename
(dropped asserts / new tautologies / skips) still fires. Adds
partitionDeletedRenamed + 6 regression tests.
