Validated in a combined 4-PR batch worktree off release/v3.8.51 tip.
- Every fix individually confirmed against the pristine tip, no runtime behavior change
- typecheck:core, file-size, changelog-integrity, complexity, cognitive-complexity, check:cycles — all OK
- Full-repo lint: 503 → 228 problems, confirming this PR's diagnosis of the exit-2 stale-suppressions + orphaned-code causes; the remaining 228 are pre-existing dashboard react-hooks/* findings this PR never claimed to touch
- node --test tests/unit/combo-routing-engine.test.ts, providers-constants-split.test.ts, and the providerLimits/videoBridge importers — all pass as part of the batch's 246/246 node:test run
Thanks for the meticulous base-red triage — this directly explains and fixes the largest lint-drift finding from the prior merge-batch session.

Thanks for applying one canonical header denylist across the generated Cloudflare/Vercel/Deno relays so hop-by-hop, framing, and proxy-auth/relay-control headers stop leaking upstream.

Merged into release/v3.8.51 via batch validation: subscription-ladder + free-regime vitest suites green (32/32) on the combined tree, check:provider-consistency OK (353 canonical providers), static gates green (virtualFactory.ts frozen at merge size with dated rebaseline). Also pushed a docs commit marking rungBudgetUsd as not-yet-enforced per review, and synced the branch onto the updated release tip. Strong opt-in design failing closed where money is involved — thanks @yourspraveen!

Resolvido o mesmo conflito não-relacionado em src/shared/utils/wsPath.ts (mesma causa do #11436 — refactor já mergeado na branch depois do fork deste PR; o diff real deste PR — bin/cli/utils/volatileEnvPath.mjs + bin/omniroute.mjs — ficou intacto) e revalidado: typecheck:core limpo, 12/12 testes focados passando.
Companion do #11436, decisão pura testável isoladamente, sem mudança de comportamento fora do caso volátil. Obrigado pela contribuição!

Validated on a 3-PR combined board: openai-responses-opencode-subagent-sessionid within the board's 20/20, typecheck:core + check:open-sse-typecheck clean, gates within baseline. Uses null as the omission sentinel for OpenCode's optional default-less subagent.sessionID under Responses/Codex strict mode (which required every declared property) — models can now omit the field to spawn a new child instead of inventing filler IDs; the null is stripped before OpenCode sees the call, real child IDs pass through unchanged. Thank you @ofonseca-pyming!
Validated on a 3-PR combined board: openapi-security-tiers 1/1 within the board's 20/20, typecheck:core clean, gates within baseline. Declares GET /api/openapi/spec's real ManagementSessionAuth contract (conditional on requireLogin) — no runtime behavior change, just the doc catching up. Closes#10851. Thank you @RaviTharuma!
Validated on a 3-PR combined board: 11018-database-cache-docs 1/1 within the board's 20/20 focused suite, typecheck:core clean, gates within baseline. DATABASE_GUIDE.md now cites the real 64 MiB runtime default and the 1..1,000,000 KiB range, locked with a regression test. Thank you @RaviTharuma!
Validated on a 3-PR combined board: traffic-inspector-beginner-header suite green within the board's 30/30, typecheck:core + dashboard-typecheck clean, gates within baseline. Purpose-first orientation header for Traffic Inspector, existing inspection UI untouched. Thank you @ignamiranda!
Validated on a 3-PR combined board: sidebar-customization + sidebar-essentials-static 30/30 combined (across the board's 4 focused files), typecheck:core + dashboard-typecheck clean, gates within baseline. New Essentials sidebar preset gives first-time users a short beginner path while advanced tools stay reachable via Command Palette search. Thank you @ignamiranda!
Validated on a 3-PR combined board: kiro-connection-identity 8/8 (written failing-first — 3 new cases red on the pristine release/v3.8.50 tip, green with this change), typecheck:core + dashboard-typecheck clean, all static gates within baseline. Root cause is exactly right: a CodeWhisperer profile ARN identifies the profile, not the account, and distinct Builder ID accounts via social login can share one — the ARN is now trusted only alongside a non-contradicting account-level identifier (email/clientId). Closes#10815. Thank you @engenhariaandrereis01-ai!
Validated on the combined 8-PR board: home-page-static 4/4, check:dashboard-typecheck clean (220 pre-existing, all within frozen baseline — zero syntax errors), 88/88 across the board's focused suites, static gates within baseline. The soft first-run readiness card replaces the hard Home→onboarding redirect with a dismissable 4-step path. Thank you @ignamiranda!
Validated on the combined 8-PR board: ollama-local-capabilities-routing 3/3, managed-model-import 9/9 (including the integration with the carried Gemini-3.5-Flash cleanup from #11259), 88/88 across the board's focused suites, typecheck:core + dashboard-typecheck clean, gates within baseline. This brings #11088 to the release line — it had squash-merged to main by base error (mine) — AND fixes the two defects the port caught: the global filter drop that leaked image/video models into OpenAI chat selections (now scoped to self-hosted providers) and the unregistered hard-lease credential site. Exemplary port discipline: byte-identical carry + the corrections in a separate reviewable commit + the superpowers docs deliberately left out. main still needs the same two-line fix. Thank you @yourspraveen!
Validated on the resolved merge against the current tip (527da656 + the post-#11281 rebaseline): the single conflict was a comment-only collision in providers/[id]/models/route.ts (kept the tip's #10828-ordering note). Focused suites 125/125 across all 13 touched test files (build-sqlite-stub, cc-compatible, copilot-claude-messages, copilot-gemini-route, executor-github, ghe-copilot, github-copilot-discovery-token, github-copilot-model-discovery, noauth-sibling-7620, provider-header-profiles, provider-models-config, request-log-payloads, upstream-error-passthrough), typecheck:core clean, file-size/changelog-integrity OK. Merged --admin over the inherited 2026-08-23 base-red cluster (#9985) — the reds are proven tip failures (CLI catalog cluster + @testing-library allowlist, being drained by #11280), not from this diff. Note: the rebase means several items the body listed (relay x-relay-path SSRF, /v1/search blocked-providers, #10736 rotation fence, #10903, #10865, #10899, #10916) already landed upstream and are NOT in this delta — the delta is: better-sqlite3 build guard + build heap/worker caps + telemetry-off (#10060 re-derived), credential-echo passthrough refusal + OCR/moderation redaction + call-log key redaction, Copilot CLI 1.0.81-6 wire identity + Claude→/v1/messages name-matched routing + discovery token fix, CC model_not_found 400, compat overrides for no-auth aliases (#7620-pinned). The Copilot wire-identity change is the one to watch in production. Thank you @arminanton — and the ported-author credits in the commit history (@rqzbeh, yidecode, the #10899/#10916 authors) are preserved. Your config-posture finding (REQUIRE_API_KEY default vs 0.0.0.0) is noted for a maintainer decision, as you scoped it.
TDD: 4 red-to-green tests reproducing the two review findings + 6 new cases; 30/30 in tests/unit/codex-app-server.test.ts; typecheck/eslint/env-doc-sync/file-size clean. Merged --admin over the inherited 2026-08-23 base-red cluster (#9985): the remaining reds (CLI catalog/registry tests, @testing-library allowlist) are proven tip failures unrelated to this diff — shard logs show only CLI-cluster failures, and this PR itself drains the mutation-test-coverage red (stryker registration for #11267's test). Behavior change for app-server deployments is documented in the PR body (sandbox default + binding refusal).
Validated on the combined 12-PR batch board + the resolved merge against the post-#11232 tip: focused suites 73/73 (learned-reasoning-effort-caps, synced-capabilities-learned-effort-override, synced-effort-suffix-learned-validation, effort-tiers-loop-catalog-e2e, reasoning-effort-clamp-and-retry, reasoning-effort-learned-capability) + opencode-plugin effort-tier-variants 4/4, typecheck:core clean, gates within baseline. The stacked-branch conflict after #11232 squash-landed was resolved by hand (the learned-caps module keeps both the Set API and the new model-scoped lookup). The effort_tiers loop is closed end-to-end: catalog advertises exactly what the upstream accepts, and -<tier> suffix variants resolve against the learned set. Thank you @maxmad64bis!
Validated on the combined 12-PR batch board: typecheck:core clean, file-size/changelog/complexity/cognitive gates within baseline, eslint config smoke-tested. Freeze-then-ratchet for @typescript-eslint/no-unused-vars scoped to src/open-sse/tests (1393 pre-existing frozen, _ escape hatch, args:all), following the #7879 pattern — plus it untracks the two docs/superpowers planning files that leaked in via #11213 and were tripping check:tracked-artifacts for everyone. Thank you @maxmad64bis!
Validated on the combined 12-PR batch board: combo-max-global-attempts-config 4/4 plus the neighboring combo suites green, typecheck:core clean, gates within baseline. clampGlobalAttempts mirrors clampComboDepth with a 200 hard cap, so a bad config can never disable the budget. Closes the configurability item from #11134. Thank you @pacocartones!
Validated on the combined 12-PR batch board: repro-7764 suite 17/17 on this tree (11/17 fail on a clean tip without the fix — proper red-to-green), typecheck:core clean, gates within baseline. Quota windows now order chronologically from the data shape instead of a provider whitelist. Thank you @pacocartones!
Validated on the combined 12-PR batch board: focused node:test suites green (incl. provider-rate-limit-overrides-schema + ratelimit-admission-control-6593 isolated 11/11 + the new EditConnectionModal vitest 3/3), typecheck:core clean, all static gates within baseline. Pushed one follow-up commit to your branch with the real Vietnamese translations for the two new keys (repo convention: vi never ships __MISSING__ placeholders). Per-connection maxWaitMs override lands, folding the zai-web exception into the general mechanism. Thank you @maxmad64bis!
Merged after conflict resolution onto the post-#10961 tip (verified no clobber of today's plaintext-wins work — the resolver functions were appended and the chatCore call-site swapped; a first --theirs attempt was caught reverting #10961 and redone hunk-by-hunk). resolveIncompatibleReasoningAction now defaults single-target incompatible reasoning to drop while combos keep their explicit strategy, with the x-omniroute-reasoning-fallback header override. 21/21 reasoning suites green, typecheck clean. Fixes#10959. Thank you @adevwithpurpose!
Validated on the combined batch board over tip 0b41259f: static gates clean, typecheck:core clean, 430+ focused tests green across 5 groups.
--tray returns after readiness and survives terminal close, with tray-mode autostart on macOS/Windows/Linux while headless Linux keeps the systemd user service. tray-detached + autostart suites green. Closes#11229. Thank you @tuandinh0801!
Validated on the combined batch board over tip 0b41259f: static gates clean (changelog, file-size 160 frozen, complexity 2628<=2774, cognitive 1187<=1223, dead-code 408<=416, docs-counts green at 351 providers, provider-consistency 268/351/0), typecheck:core clean, 430+ focused tests green across 5 groups.
max_context_window now wins over the pricing-tier context_window in Codex catalog parsing — context-aware fallback stops demoting codex behind smaller targets. Live evidence (390K served past 272K) plus the live-shape regression test. Thank you @excessivechaos!
Validated on the combined batch board + this branch: synced-inventory + auth neighbor suites 16/16; file-size gate green with the auth.ts 3337 frozen entry (dated annotation for the +77 inventory-filter lines at the credential-selection chokepoint, owner-authorized). Chat routing now pins to the connection whose synced inventory actually advertises the model — no more spurious model-not-found on multi-host self-hosted setups. Scoping call (not building on the still-open #11088) was the right one. Fixes#11089. Thank you @pacocartones and @yourspraveen for the precise report!
Validated on the combined batch board over tip c92bd40b: static gates clean (changelog, file-size 158 frozen, complexity 2626<=2774, cognitive 1183<=1223, dead-code 409<=416), typecheck:core clean, 70 focused tests green (PR suites 49/49 + auth/combo neighbors 21/21).
Keyless custom-compatible connections stay in auto/* pools — the credential filter now recognizes a registry-free keyless endpoint instead of dropping the connection before pool construction. Fixes#11180. Thank you @pacocartones!
Validated on the combined batch board over tip c92bd40b: static gates clean (changelog, file-size 158 frozen, complexity 2626<=2774, cognitive 1183<=1223, dead-code 409<=416), typecheck:core clean, 70 focused tests green (PR suites 49/49 + auth/combo neighbors 21/21).
Five g4f-* entries re-flagged hasFree:false with the live-probed 402 evidence (proof-of-work wall, member key still works); the two dissenting providers deliberately untouched, matching the chutes/aimlapi/yi precedent. Fixes#10071. Thank you @pacocartones and @chirag127 for the capture!
Validated on the combined batch board over tip c92bd40b: static gates clean (changelog, file-size 158 frozen, complexity 2626<=2774, cognitive 1183<=1223, dead-code 409<=416), typecheck:core clean, 70 focused tests green (PR suites 49/49 + auth/combo neighbors 21/21).
Operator-configured positive minTime floor now survives the plenty-of-headroom relaxation (resolveMinTime instead of a hard 0). Fixes#9763. Thank you @pacocartones!
Merged after count reconciliation: the branch's regenerated docs claimed 57 free forever / 157 migrations from its older base; gate-verified values on the current tip are 56 free forever (Logfare carries a Free badge via gateways.ts freeNote but has no freeModelCatalog per-model entries, so the live-code counter stays at 56) and 159 migrations — the README/SVGs now match the check:docs-counts output exactly. provider-consistency OK at 267 registry / 349 canonical. logfare-registry 4/4, icon + KNOWN_PNGS + discovery-set membership all verified present. Closes#10644. Thank you @jonlwheat2-gif!
Validated on the combined batch board + this branch: 231/231 across chatcore-translation-paths, reasoning-cache, strip-reasoning-blobs, and both Responses translator suites. Pre-merge: propagated the #11110/#11129 summary:[] defaults into five assertions here (each commented with its PR) — without it this branch red against the tip, and as a bonus the merge drains the 4 reasoning reds that were live on the tip from those merges. Plaintext now wins over a coexisting opaque companion; opaque-only drops cleanly for plaintext targets; combos keep explicit Skip. Fixes#10949 and #10959. Thank you @jackjinke!
Validated on the combined batch board + this branch alone: chat-body-admission + authz/pipeline 65/65, file-size gate green with a dated frozen entry (chatBodyAdmission 1005→1009 — the +4 lease/drain wiring lines, owner-authorized rebaseline). trackRequest was never called, so SIGTERM waitForDrain saw zero in-flight and killed live SSE; leases now hold the drain counter for the stream's lifetime, and the 503 carries Retry-After. Closes#11015. Thank you @RaviTharuma!
* feat(api): structured ?format=json for the self-service usage endpoint
GET /api/usage/om-usage already let any key read its own usage — personal
daily/weekly USD limits and the provider quota snapshot — but only as
text/plain, which a UI cannot parse safely. OmniCopilot issue #8 asks exactly
for this surface.
Adds ?format=json, returning the ApiKeyUsageLimitStatus + UsageSnapshot the
text is rendered from. Text and JSON share the same collectors
(collectUsageSnapshots, getApiKeyUsageLimitStatus), so the two can never
disagree about a number. The response is a discriminated union: a key without
allowUsageCommand (403) or an invalid key (401) returns
{ allowed:false, error:{message} }, distinct from allowed:true with empty
sections — the state a panel must render as "nothing learned yet", not a
refusal. Text form unchanged; without ?format the contract is untouched.
The endpoint was previously missing from API_REFERENCE.md; it now has a
section documenting both forms, the allowUsageCommand gate, and the
self-service auth model (caller's own key, not requireManagementAuth).
Regression guards in tests/unit/usage-command-json-format.test.ts (4 tests:
json shape, text default preserved, structured 403, sanitized 401 with no
stack trace). Existing internal-usage-command suite still 12/12.
* chore(changelog): correct the fragment to the real PR number (#11190)
* feat(api): return every connection's snapshot under providers[] in om-usage json
Closes#11191. buildUsageCommandJson picked a single snapshot via selectUsageSnapshot, so a panel could only ever show one provider. The collector already had them all — the single-pick is a presentation choice for a terminal. The JSON form now also returns the full UsageSnapshot[] alongside the selected provider, so a UI can render Codex / Claude / OpenCode side by side. The text form is untouched.
