From 37084c24a8ee610337ada65d3659344e04bcddc7 Mon Sep 17 00:00:00 2001 From: bitkyc08-arch Date: Fri, 14 Aug 2026 18:37:27 +0900 Subject: [PATCH 01/16] docs(devlog): Lab/core decoupling roadmap + owner-only core CODEOWNERS The Compatibility Lab reaches the proxy core on the mandatory path: a user with no routing profile still executes Lab code on every request and loads the Lab module graph at startup. The measured cost is small; the architectural cost is not, and there is no way to decline it. Roadmap unit devlog/_plan/260814_lab_core_decoupling/ records six verified coupling points and the import cycle that makes them expensive: routing/compatibility/assemble -> routing/quota -> providers/quota -> codex/auth-api -> codex/native-main-admission -> server/lifecycle -> lab/automation/orchestrator That cycle pulls ~69 src/lab files into the graph, so cutting the lifecycle edge is phase 1 rather than the most visible symptom. Design is registration, not dynamic import: core declares slots, Lab registers into them at activation. Routing stays synchronous because making it async to relocate an import would touch ~283 call sites and break the sync subagent-fallback API. 060 records an independent adversarial audit (FAIL, 5 blockers) and the amendments. The most serious: the planned deferred-activation window was fail-closed, not degrade-open -- compatibility unknownEvidence defaults to exclude, so a policy request in that window throws NoEligiblePolicyCandidateError rather than losing evidence. Phase 3 now awaits activation before policy routing. CODEOWNERS adds an owner-only block for the four core files, placed after /src/server/ so last-match-wins takes effect. Branch protection on dev now requires code-owner review. No runtime code changes in this commit. --- .github/CODEOWNERS | 12 + .../260814_lab_core_decoupling/000_plan.md | 138 +++++++++ .../010_lifecycle_shutdown_registry.md | 176 ++++++++++++ .../020_request_path_gate.md | 199 +++++++++++++ .../030_router_and_startup_activation.md | 261 ++++++++++++++++++ .../040_boundary_guard_test.md | 96 +++++++ .../050_governance_and_release.md | 132 +++++++++ .../060_audit_round1_amendments.md | 157 +++++++++++ 8 files changed, 1171 insertions(+) create mode 100644 devlog/_plan/260814_lab_core_decoupling/000_plan.md create mode 100644 devlog/_plan/260814_lab_core_decoupling/010_lifecycle_shutdown_registry.md create mode 100644 devlog/_plan/260814_lab_core_decoupling/020_request_path_gate.md create mode 100644 devlog/_plan/260814_lab_core_decoupling/030_router_and_startup_activation.md create mode 100644 devlog/_plan/260814_lab_core_decoupling/040_boundary_guard_test.md create mode 100644 devlog/_plan/260814_lab_core_decoupling/050_governance_and_release.md create mode 100644 devlog/_plan/260814_lab_core_decoupling/060_audit_round1_amendments.md diff --git a/.github/CODEOWNERS b/.github/CODEOWNERS index 567a8d6d69..ed9747ba00 100644 --- a/.github/CODEOWNERS +++ b/.github/CODEOWNERS @@ -32,3 +32,15 @@ **/AGENTS.md @lidge-jun @Ingwannu /MAINTAINERS.md @lidge-jun @Ingwannu /SECURITY.md @lidge-jun @Ingwannu + +# Proxy core boundary — owner approval required. +# These four files carry every user's request path, including users of no optional +# subsystem.

Gating keeps +the feature for installs that opted in. **This unit gates; it does not delete.** Scope +boundary for anyone extending this work: removing CL-09 entirely is a separate decision +with its own user-facing deprecation, not a side effect of a boundary fix. + +### The routing constraint that shapes everything + +`routeModelInternal` (`src/router.ts:504`) is **synchronous**, and so are its public +wrappers `routeModel` (`654`) and `routeConcreteModel` (`684`). A dynamic `import()` +inside it is impossible without making the chain async, which would touch ~11 production +call expressions, ~272 test call sites, and — the actual blocker — the synchronous +subagent-fallback API in `src/codex/subagent-model-fallback.ts` (`tryRouteFallbackModel:63` +feeding `isNativeModelQuotaExhausted:200`, `isModelHealthBlocked:216`, +`isSubagentModelUnavailable:234`, `selectAvailableSubagentModel:269`, +`noteSubagentModelFailure:298`, `applySubagentModelFallback:510`). + +Making routing async to remove a Lab import would be a far larger and riskier change than +the problem justifies. **Routing stays synchronous.** The boundary is drawn with a +provider-registration seam instead. + +## Design: registration, not dynamic import + +The core already owns the exact pattern needed — `src/lib/server-resource-ownership.ts`, +`registerCurrentServerResourceCleanup` — and Lab already consumes it at +`lab/automation/orchestrator.ts:104`. This unit generalizes that idea rather than +inventing a mechanism: + +- Core declares a **slot** (a nullable function reference) for each optional Lab capability. +- Core calls the slot when populated, and skips when null.

From 9d979f6e465f5253e346981a825bb9e45f46bb38 Mon Sep 17 00:00:00 2001 From: bitkyc08-arch Date: Fri, 14 Aug 2026 18:44:51 +0900 Subject: [PATCH 02/16] =?UTF-8?q?docs(devlog):=20audit=20rounds=202-3=20?= =?UTF-8?q?=E2=80=94=20remove=20the=20activation=20window=20entirely?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Round 2 (FAIL, 4 blockers) found that the round-1 readiness-gate fix introduced worse defects than it closed. The reviewer proved three by executing the real modules: during a deferred-activation window a policy alias in a subagent fallback chain is silently skipped and the subagent runs on a different model than the operator configured -- no error, no log, only a skipped entry. The reviewer's key observation: that window does not exist today. Static imports make compatibility evidence load synchronously. My own deferral created it. 070 removes deactivation from scope (reconcile only ever activates; a create-then-delete user keeps Lab resident until restart, which does not affect users who never opted in). 080 is a self-correction made while round 3 was in flight. I verified that readinessGate is NOT admission control -- it appears three times in server/index.ts and the only read is inside the /ready response body at :852, a status report for external supervisors. So 070's A1 rested on a false premise. The resolution is to never make activation asynchronous. server/index.ts already imports Lab statically and already runs its startup block synchronously; the protected set is corrected to three files, with server/index.ts treated as an unprotected composition root. A composition root is supposed to know which optional subsystems exist. Bun.serve binds at :1638 and the Lab block sits at :1738, so I verified the gap: the three awaits in that range are inside the server.stop closure, the one .then is fire-and-forget quota priming, and scheduleStartupRun is documented as never blocking listen. The path is synchronous, so no request can be handled before activation. That ordering is now stated as an invariant and phase 4 asserts it. No runtime code changes in this commit. --- .../070_audit_round2_amendments.md | 159 ++++++++++++++++++ .../080_activation_is_synchronous.md | 152 +++++++++++++++++ 2 files changed, 311 insertions(+) create mode 100644 devlog/_plan/260814_lab_core_decoupling/070_audit_round2_amendments.md create mode 100644 devlog/_plan/260814_lab_core_decoupling/080_activation_is_synchronous.md diff --git a/devlog/_plan/260814_lab_core_decoupling/070_audit_round2_amendments.md b/devlog/_plan/260814_lab_core_decoupling/070_audit_round2_amendments.md new file mode 100644 index 0000000000..bc0f701bb4 --- /dev/null +++ b/devlog/_plan/260814_lab_core_decoupling/070_audit_round2_amendments.md @@ -0,0 +1,159 @@ +# 070 — Audit round 2: eliminating the activation window + +Unit: `260814_lab_core_decoupling`.

Core now owns a shutdown-hook registry and never names Lab. Lab registers its teardown inside setLabAutomationDispatchDeps, next to the existing registerCurrentServerResourceCleanup lease, so activation and teardown registration cannot drift apart. A process that never activates Lab registers nothing and shutdown does no work. Measured on the module graph, runtime imports only: src/server/lifecycle.ts 69 -> 0 reachable src/lab modules src/router.ts 24 (phase 2/3 scope, via compatibility/subject) src/server/responses/core.ts 24 (phase 2/3 scope, same path) One deliberate behavior change: teardown is now scoped to the activated configDir, where the previous shutdown call passed none and keyed on the default. setLabAutomationDispatchDeps is per-configDir, so those disagreed in multi-config test processes. Verification: bun x tsc --noEmit exit 0; 7 new hook tests pass; 52 lab-automation tests across 7 files pass; repo-hygiene and lab-passive-production-evidence pass.

That covers the startup path, but the management API and the CLI can start a scheduler without ever installing dispatch deps: server/management/lab-automation-routes.ts:69 applySchedulerPolicy cli/lab.ts:399 In those cases no hook existed, and since core no longer imports the orchestrator to stop it, the scheduler survived drainAndShutdown -- a live interval leaking past shutdown. Enabling Lab automation from the dashboard was enough to hit it. Proven before fixing: a probe asserting the scheduler stops after runOptionalShutdownHooks failed with runningAfter=true, then passed after the change. That probe is now a permanent regression test. startLabAutomationScheduler registers its own keyed teardown, so the hook exists whenever a timer exists regardless of which entry point created it. The two keys are distinct (lab-automation: vs lab-automation-scheduler:), and the registry replaces by key, so repeated starts cannot accumulate hooks. Verification: bun x tsc --noEmit exit 0; 60 tests pass across 8 files (52 lab-automation + 8 shutdown-hook).

The call is not free even when it produces nothing: resolveCompatibilitySubjectsForInboundWire builds a Lab protocol subject and digests it before it checks for an installation salt, so an install with no routing profile ran Lab digest work per request and discarded it. Core now holds a nullable slot. It resolves to null unless an opt-in subsystem registered a linker, and the non-throwing guarantee lives in the slot helper rather than being restated at the call site. The Lab implementation moves to src/lib/lab-passive-linker-registration.ts, alongside the other lab-* host integrations, to be installed at activation in phase 3. CL-09 keeps working for installs that opt in: labRouteSubjectId is unchanged in usage/log.ts, and passive-production, the management route, the CLI, and the Compatibility Matrix all read the same field. Nothing is retired. The CL-09 architecture guard is inverted rather than deleted, as 020 planned: it asserted core CONTAINS resolveProductionRouteSubject, and now asserts core contains neither it nor any routing/compatibility import, with the positive assertion moved onto the registration module. responses/core.ts still reaches Lab transitively through router.ts -> routing/compatibility/assemble.ts -> catalog.ts -> lab/query/catalog.ts.

Module graph, runtime imports only: lifecycle.ts 69 -> 0 reachable src/lab modules. router.ts and responses/core.ts remain at 24 through a single traced chain (router -> assemble -> catalog -> lab/query/catalog), which is phase 3. Both boundary guards were driven red before being trusted: reintroducing the Lab import into responses/core.ts failed the new boundary test and the inverted CL-09 guard, and the phase-1 scheduler leak showed runningAfter=true before its fix. The remote Linux full suite reported 127 failures. Recorded as a pre-existing full-suite condition rather than absorbed silently, on three independent grounds: no Lab or boundary test is among them; every sampled failing file passes standalone on the same host and commit; and a clean dev baseline at c6688c7 on the same runner accumulated failures on the same trajectory (19 -> 112) and converges toward the branch count. That is cross-file interference in an unsharded run -- which is why CI shards the suite into four fresh-process batches (#1469).

Making it async to permit a dynamic import would touch ~283 call sites and break the sync subagent-fallback API (isNativeModelQuotaExhausted, isModelHealthBlocked, selectAvailableSubagentModel and friends have nowhere to await), so the seam is a nullable provider slot instead. assemble.ts keeps capability, health, quota, and cost -- the evidence routing always needs -- and consults the slot for compatibility. The Lab-reaching half (subject resolution, catalog snapshot, projection read, attachCompatibilityEvidence) moves verbatim into lab-evidence-provider.ts; its state already arrived entirely through arguments, so this is a relocation, not a rewrite. With no provider registered the evaluator sees no compatibility evidence and scores exactly as it did before compatibility policy existed. Per audit B5 the options type splits along the same seam: CoreEvidenceOptions carries configDir and routedProviderConfig, while the three Lab test seams belong to LabCompatibilityProviderOptions. AssemblePolicyEvidenceOptions remains as an alias so existing callers keep compiling. Activation is synchronous and gated. server/index.ts calls activateLab only when labActivationRequired -- any routing profile, or automation enabled on disk -- and does so in the same synchronous turn as Bun.serve, so no request can observe an unregistered slot. Three audit rounds established that a deferred window is unpatchable: the sync fallback chain would silently drop a policy alias and run the subagent on a different model than the operator configured. labAutomationEnabledOnDisk mirrors loadLabAutomationConfig precedence (automation-config.json first, automation-policy.json legacy) with plain node:fs, so the detector never imports Lab to decide whether to import Lab. Audit R3-1 and R3-2 are closed: the dry-run endpoint and the profile-create path both activate first, so an operator preview cannot disagree with production, and both resolve configDir the way the startup block does. tests/core-lab-boundary.test.ts enforces the property with a transitive import-graph walk, not a regex -- the original defect hid in a six-hop chain where no single file looked wrong. Driven red: reintroducing a direct Lab import into router.ts failed both guards and printed the chain 'src/router.ts -> src/lab/paths.ts'. Verification: bun x tsc --noEmit exit 0; 84 tests pass across 6 boundary/Lab files; 34 routing tests pass; 6 boundary guards pass.

The walker matched static imports, side-effect imports, and runtime re-exports, but not dynamic import(). The regex now covers all four forms, and the four attacks plus a type-only negative case are permanent tests that synthesize each import shape against a temporary probe file. A guard that only matches the shapes which happen to exist today would rot silently -- these fail if the walker regresses. Type-only imports stay excluded: they are erased at build time, so they are not runtime edges, and the negative test pins that distinction rather than leaving it implicit.

This sat on the startup path of every install with a routing profile, because activateLab reaches the scheduler branch regardless of why activation was required. Reproduced in an isolated configDir: threw 'invalid policy layers', provider slot registered, activation record absent -- so the receipts were orphaned and a later activateLab would register the slots a second time. A partially written automation file now disables Lab automation for the run and logs what to fix; routing, evidence, and everything else keep working. The activation record is stored before the scheduler call so a throw cannot leave slots and record inconsistent. The pre-phase-3 code read the legacy file through loadLabAutomationPolicy and never ran the combined-config normalizer, so this was a regression introduced by the boundary work, not a pre-existing condition. Also from the audit: the activation-key invariant is now written down (activation is all-or-nothing and reason-independent, which is what makes configDir a safe key -- if a registration ever becomes conditional, the key must include the reason), and the guard's known limits are stated rather than implied (a static walker cannot resolve computed specifiers; require() is unavailable in an ESM package). Adds tests/lab-activation.test.ts (10) covering the crash regression, the bare install registering nothing, idempotence, the automation-only-then-profile ordering trap, and all six detection-precedence cases; plus tests/compatibility-provider-equivalence.test.ts pinning that every candidate gets a compatibility object when requirements exist -- including unresolvable ones -- and none when no provider is registered.

The file was fine -- the cause was contention -- so the message sent the operator to fix the wrong thing. The two causes now get different messages because they need different actions, and the lock case says it will retry on the next start rather than implying corruption. Also records why the failure asymmetry is deliberate: startup degrades with a warning, while the management API and CLI let LabAutomationError surface (the route maps it to a 400). Someone toggling automation should see the validation error; someone merely starting the proxy should not lose unrelated traffic. Adds coverage for a failed scheduler start leaving nothing dangling: the shutdown hook is registered before the throw, so a hook exists with no timer behind it -- verified harmless (no running scheduler, hooks run without throwing). Test isolation fix: the provider and linker slots are process-global, so a sibling test file that registered one leaked into the bare-install assertion. beforeEach now resets the slots themselves, not just the activation record.
