Replace the hand-written HTTP dispatcher with a Hono app fed by a framework-neutral route catalog behind one fail-closed admission pipeline. - keep authentication, RBAC, service grants, sandbox fallback, SCM compatibility, cache policy, and response headers as explicit catalog policy enforced before every handler - audit authorization decisions from the admission layer and dispatch - finalize a service actor's canonical user before RBAC so the user authorized is the user attributed - build the Hono app from a catalog factory so tests compose routes - cover every catalog route through the Worker per credential class Claude-Session: https://claude.ai/code/session_01KdDpTgGEjXpBA9SaGQVUH1

Summary
PR #1716, refactor: migrate control plane routing to Hono, by @ColeMurray migrates the control-plane dispatcher to a Hono adapter backed by a framework-neutral 171-route catalog and centralized admission pipeline. The review covered 82 changed files (+4,817/-1,767); no blocking correctness or security regressions were found.
Critical Issues
None.
Suggestions
- [Testing]
packages/control-plane/test/integration/route-admission-matrix.test.ts:147- Recreate the automation fixture for each destructive/mutating automation route so the matrix exercises admitted handler paths instead of freezing several post-delete 404s. - [Observability]
packages/control-plane/src/routing/hono-app.ts:60- Start latency measurement beforeapp.fetchso route matching remains included inhttp.request.duration_ms, preserving comparability with the legacy router.
Nitpicks
None.
Positive Feedback
- The adapter retains a separate raw-path matcher and validates the supported path grammar, avoiding subtle Hono decoding and route-syntax changes.
- Authentication, service ceilings, actor finalization, active-user checks, RBAC, and resource admission are centralized in an explicit fail-closed sequence.
- Compatibility tests cover strict paths, encoded captures, unsupported HEAD, universal OPTIONS, response headers, streaming responses, exception mapping, and Worker lifecycle boundaries. Control-plane typecheck, unit tests, and integration tests pass.
Questions
None.
Verdict
Approve: Ready to merge; the inline suggestions are non-blocking test/telemetry improvements.

The loop reuses one automation fixture, but DELETE /automations/:id removes it before the subsequent pause, resume, trigger, invocation, run, and regenerate-key cases. The snapshot therefore freezes those routes as handler-owned 404s rather than exercising their admitted behavior. Could we create a fresh automation for each mutating automation route, as this test already does for session mutations?
There was a problem hiding this comment.
Done in 8d11c28. Each mutating automation route gets its own automation. The snapshot now records pause/resume 200, trigger 201, invocations 200, regenerate-key 400 instead of post-delete 404s.

startedAt is now captured inside Hono middleware, after Hono has parsed and matched the route, whereas the legacy router started timing before route selection. This makes http.request.duration_ms discontinuous across the migration and excludes the adapter work we would want to observe. Could the outer handler capture the start time before app.fetch and pass it into the request context?
There was a problem hiding this comment.
Done in 8d11c28. The outer handler records the start time before Hono selects a route and the middleware picks it up, so duration_ms is continuous with the legacy router.
There was a problem hiding this comment.
The Hono adapter and route catalog are a meaningful improvement over the 1,064-line dispatcher, but the new admission design is not safe to merge yet. The most serious issue is that canonicalization is only performed for first-contact actors: an actor previously enrolled without profile claims can retain a default Member role and bypass the attested email owner's Viewer, suspension, or assignment state. This regresses the protection on main, contradicts the new identity-bearing actorEmail contract, and is explicitly frozen as a successful 201 in the added test.
There is also a broader structural problem in the admission boundary: invalid route input can mutate identity/RBAC state before returning 400, while invalid authentication/authorization combinations remain representable and are handled by a principal-less allow branch. The code-judo move is to make route policy a discriminated, valid-by-construction model and make actor claim preparation a rejecting/prepared-input transition before any identity mutation. That should delete several defensive special cases rather than adding more checks to the 772-line admission pipeline.
Finally, the new positive admission matrix treats every non-401/403 response, including 500/503, as proof of admission. A policy-preserving shadow catalog with sentinel handlers would test admission directly and keep real-handler compatibility separate.
Requesting changes for the identity/RBAC bypass and the fail-open/non-atomic admission structure.

[deep review] This early return defeats the admission-side identity fix for any actor that was previously enrolled without profile claims. A Slack/Linear actor can first hit a claimless active-user route and receive the default Member role; on a later POST /sessions, authentication supplies that canonicalUserId, so this returns before reading the signed actorEmail. RBAC then runs as the provisional Member even when the attested email belongs to a Viewer, suspended user, or unassigned user, and the session is created under the wrong authorization subject. main's handler-side relink/409 prevented that sequence, while the new test at service-auth.test.ts:751-794 explicitly expects a 201. Claim-bearing routes must resolve claims even for known identities, update the principal to the final canonical user, and run RBAC exactly once against that user. Please add a real two-request regression: enroll through a claimless route, then attempt session creation with Viewer/suspended/unassigned attested email.
There was a problem hiding this comment.
Agreed the gap is real, but it is not a regression: main's resolveCanonicalUserId also returned early for any actor with a canonicalUserId, so a known actor was never relinked there either. Relinking a known identity to the attested email's owner is effectively a user merge and changes which account a Slack or Linear user is, which is a product decision rather than something this routing PR should decide. I've kept the current behavior, noted it explicitly in the PR description, and propose a follow-up issue for the relink policy plus the two-request regression you describe.

There was a problem hiding this comment.
[deep review] null conflates 'valid request with no profile claims' with 'the route rejected this body'. extractSessionActorProfileClaims returns null for malformed JSON and forbidden identity fields, but admission still calls resolveOrCreateUser, creating a user, provider identity, and default role assignment before the handler returns 400. The added test currently blesses that partial state. A rejected operation should not mutate authorization state. Make preparation return a discriminated accepted/rejected result and stop before identity mutation; ideally parse/validate once and pass the prepared typed input to the handler instead of maintaining two body-validation paths.
There was a problem hiding this comment.
Done in 8d11c28. serviceActorClaims now returns { kind: "claims" } or { kind: "rejected", response }; a rejection ends admission with the route's own 400 and writes no user, identity, or assignment. The integration test now asserts zero identity rows for malformed JSON and forbidden fields. Parsing once and handing typed input to the handler is a good follow-up but touches the handler contract, so I left it out of this PR.

There was a problem hiding this comment.
[deep review] This is fail-open at the exact boundary described as fail-closed: an absent principal is allowed without considering the authorization policy. RouteAuthentication and RouteAuthorization are independent types, so public/handler-authenticated can currently be combined with active-user, active-self, or service; a catalog test checks today's production objects, but defineRoute and the exported catalog factory still accept the invalid state. The same optional-subject assumption leaks into permission checks below. The structural fix is a discriminated route-policy union that makes legal authentication/authorization pairs representable and gives admission an exhaustive switch with a non-optional subject for human RBAC. At minimum, principal-less admission must reject every policy except the explicit no-authorization cases.
There was a problem hiding this comment.
Done in 8d11c28. A request without a verified principal is now denied unless the route declares no authorization, and createControlPlaneHttpHandler refuses at build time to register a public or handler-authenticated route that carries an authorization policy. I agree a discriminated route-policy union is the structural fix, but it reshapes every route module's declaration and I'd rather do that as its own change on top of this one.

[deep review] This does not establish that the named service was admitted: every 400/404/409/428/500/503 response passes, and the browser/sandbox positive loops use the same criterion. Because most requests intentionally send invalid {} bodies and incomplete infrastructure fixtures, an admission regression returning the same broad class of handler/infrastructure status can be blessed as coverage. Preserve each production route's policy in a shadow catalog but replace handlers with deterministic sentinel responses/spies; then assert valid credentials reach the sentinel and invalid credentials do not. Keep the real-handler response snapshots as a separate compatibility suite.
There was a problem hiding this comment.
Done in 8d11c28. A second suite keeps every production policy, replaces every handler with a sentinel, and asserts per route that the accepted credential classes reach the sentinel and the rejected ones (anonymous, wrong bot, bot actor on user-only routes, wrong sandbox token, web on sandbox-only routes) do not. The real-handler status snapshots stay as the separate compatibility record.
- stop admission before any identity write when the route rejects the body; the claims hook now returns an accepted or rejected result - deny a principal-less request unless the route declares no authorization, and reject that pairing when the Hono app is built - capture request start before Hono route selection - prove admission per credential class on a policy-preserving shadow catalog with sentinel handlers - recreate the automation fixture per mutating route and clean D1 after the matrix suite - share the request-context and common-header construction - keep WebSocket upgrades outside the Hono box in the README diagram Claude-Session: https://claude.ai/code/session_01KdDpTgGEjXpBA9SaGQVUH1

Thanks for the deep pass. Addressed in 8d11c28: rejected bodies no longer mutate identity state, principal-less admission is closed unless the route declares no authorization, and the admission matrix now proves each credential class against sentinel handlers. On the known-actor relink: main had the same early return, so I've treated it as a pre-existing policy question and proposed a follow-up rather than deciding relink semantics inside this routing change. Details in the inline threads. CodeRabbit nitpicks: the follow-ups plan doc was removed from this PR; the shared request-context and common-header helpers are extracted in 8d11c28. |

…1720) ## Summary First step of the follow-up series that retires the routing adapter left by #1716. This PR adds only tests; no production behavior changes. **Encoded path segments are pinned** (`test/integration/route-admission-matrix.test.ts`). Two new tests through the real Worker and the sentinel catalog: - Session ids reach the index lookup and the sandbox token binding as the raw segment. An encoded letter in the id misses (404 for the owner, 401 for a sandbox token that verifies against the un-encoded session). - Repository handlers decode owner and name exactly once: a nested owner (`group%2Fsubgroup`) is one segment, a slash in the name (`web%2Fapp`) is refused after that decode, and a doubly-encoded slash (`web%252Fapp`) survives because nothing decodes it a second time. - RBAC member ids decode once too: an id that is canonical only after a second decode is refused with 400. - The sentinel test replaces every handler with one that echoes `match.groups`, proving the adapter delivers `abc%2Fdef`, `group%2Fsubgroup` / `web%252Fapp`, and a doubly-encoded member id untouched. Why these matter: the next PR moves parameter access to Hono, whose `c.req.param()` decodes values, so these tests are the red-then-green story for keeping raw segments where handlers decode themselves. **Dropped during review:** an earlier revision carried a route-policy registry with a build-time walk over `app.routes`. Reconstructing handler chains from Hono's flat route list needed positional rules and an unwrap for mounted sub-apps, which is more machinery than the guarantee deserves. The "every route is admitted" invariant will instead be enforced at request time in the next PR: the lifecycle middleware refuses any response that admission did not precede, and the matrix test exercises every route in CI so a route registered without `admit()` fails before deploy. ## Verification - Unit: 231 files, 3,459 passed. - Integration (workerd, real D1): 96 files, 1,128 passed on the first revision; the matrix suite re-run green after the registry was removed. The four matrix snapshots are byte-identical. - Typecheck (`src`, `tsconfig.test.json`, `test/integration`), ESLint, and Prettier clean. https://claude.ai/code/session_01KdDpTgGEjXpBA9SaGQVUH1
#1716 replaced parsePattern/pattern with Hono paths, so the budget proxy route now declares `path`. It is registered after the existing proxy routes and added to the frozen route catalog (172 routes, 131 paths) with its admission snapshots. Claude-Session: https://claude.ai/code/session_01E3k9fw7GE4HMYHh86vKxXp
## Summary Second step of the series retiring the routing adapter left by #1716 (guardrails landed in #1720). This PR replaces the mechanism around every route while leaving all 171 route handlers untouched; after it, the remaining shim is one `legacy()` adapter function that later PRs delete module by module. **Admission is Hono middleware.** `admit(policy)` (`src/routing/admit.ts`) evaluates the route's declarative policy through the unchanged `admitRoute()` pipeline and sets `c.var.admission`. Denials answer from the middleware, with an authorization denial audited before anything is logged, as before. A principal-less policy that requires authorization is refused when the middleware is built. **The lifecycle is one `app.use("*")`** (`src/routing/hono-app.ts`) that owns what `dispatchMatchedRoute` and the outer handler used to: the DB guard (undecorated 503), the HEAD guard (404, never Hono's implicit GET), the request context and start time, the request log, the audit of allowed decisions after the handler including the 500 path, and the common response headers with the route's `Cache-Control`. `app.onError` maps `HttpError` to the `{ error }` envelope and logs anything else as the sanitized 500; a non-`Error` throw takes the same path. **Default deny.** If a handler answers without `admit()` having run ahead of it, the lifecycle replaces the response with a sanitized 500, drops the handler's headers, and logs `router.unadmitted_response`. Every policy, including `public`, sets the admission variable, so a route registered without `admit()` fails closed on its first request; the matrix suite drives every route in CI. This is the request-time check chosen in review of #1720 over the build-time registry. **Host-injected entrypoint.** `createControlPlaneApp(catalog, host)` takes a host whose one job is to build the `BackgroundTasks` port from whatever the platform passed as the execution context. `cloudflareHost` wraps `waitUntil`; the unit-test host hands the port straight through, which deletes the fake `ExecutionContext` in `router.test-support.ts`. `handleControlPlaneHttp` and `createControlPlaneHttpHandler` keep their signatures, so `index.ts` is unchanged. **Deleted:** `Route.pattern`, `parsePattern`, the raw-path re-match and its `router.match_mismatch` branch, `route-dispatch.ts`, the start-time `WeakMap`. Admission now takes `params: RouteParams` (raw segments read back from the pathname by position, `src/routing/route-params.ts`) instead of a `RegExpMatchArray`, and `legacyMatch()` rebuilds the array handlers still read from those params. **Test changes.** Unit tests that selected routes by `route.pattern` use `matchRoute()` / `routePathPattern()` from test support instead; no assertions changed. The conformance snapshot drops the `pattern` field from each of its 171 rows (identities, groups, policies, and order verified identical before and after). New `hono-app.test.ts` covers the default deny (including header non-leakage), preflight and 404 exemptions, HEAD, `HttpError` mapping, unexpected and non-`Error` throws, and both build-time refusals. ## Behavior notes - No status, body, header, or log-ordering change on any route. The four route-matrix snapshots are byte-identical. - The request-duration clock now starts in the lifecycle middleware, after Hono selects the route, rather than before `app.fetch`. The difference is the router lookup. - Parameter values handlers see are still raw. Decoding by default arrives with the module conversions. ## Verification - Unit: 232 files, 3,464 passed. - Integration (workerd, real D1): 96 files, 1,128 passed. - Typecheck (`src`, `tsconfig.test.json`, `test/integration`), ESLint, and Prettier clean. https://claude.ai/code/session_01KdDpTgGEjXpBA9SaGQVUH1 <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Improvements** * Updated request routing and authorization handling for more consistent policy enforcement. * Improved handling of denied requests, unexpected errors, unsupported methods, and route-related failures. * Strengthened route validation, including authorization requirements and duplicate parameter detection. * Improved request lifecycle behavior, including logging, trace identifiers, response finalization, and CORS preflight handling. * **Bug Fixes** * Improved extraction and handling of route parameters, including sandbox session-related requests. * Ensured unexpected handler failures return a consistent server error response with the appropriate headers and response policy. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

Summary
Replaces the hand-written control-plane HTTP dispatcher (
src/router.ts) with a Hono app fed by a framework-neutral route catalog, behind one fail-closed admission pipeline.The work was reconciled with the current
mainand then reviewed. Sibling PR on the prod fork: ColeMurray/open-inspect-claude-prod#134. Every catalog route now has Worker-boundary integration coverage.Reconciliation with main
serviceauthentication kind:/internal/github-eventand/internal/slack-eventreject human principals centrally with 403principal_type_required.GET /analytics/dashboard(feat: add coherent analytics dashboard snapshots #1705) andGET /audit-events(feat: add workspace audit log viewer #1696). Catalog is now 171 routes./healthno longer queries D1.actor_identity_changedretry. This branch fixes it admission-side by finalizing the service actor before RBAC, which needs no retry and never enrolls a denied bot. The admission-side design is kept and the 409 path is dropped. No client consumed the 409 (verified across slack-bot, linear-bot, github-bot, web, shared).createControlPlaneHttpHandler(catalog)builds the Hono app from an explicit catalog. Hono registers routes at build time, so tests that need synthetic routes build their own handler (createTestRequestHandler) instead of pushing into the productionroutesarray.Review
Three independent review passes (adapter vs legacy router, actor-finalization security, route conversions and tests). No P0 or P1 regressions. Route precedence was verified empirically against the legacy first-match semantics across 68,435 method and path probes with zero mismatches.
Fixed in this PR:
:paramgrammar are rejected when the Hono app is built, and a Hono-selects/regex-rejects mismatch is logged instead of failing silently.principal_service;serviceis a reserved logger key and was silently dropped.Carried forward (pre-existing on main):
serviceActorClaims(for example a thread reply posting/sessions/:id/prompt) is enrolled as a fresh Member, and laterPOST /sessionsrequests never consult the email owner's role or suspension. Resolving this needs a product decision on relinking known actors.Endpoint coverage
test/integration/route-admission-matrix.test.tsdrives all 171 catalog routes throughSELF.fetch:/sessions/:id/*routes and a seeded automation for/automations/:id/*;service_capability_required;Observed statuses are frozen per route in a snapshot so any endpoint's admission or handler-owned outcome change is a reviewable diff. Before this file, 51 of the 171 routes had no integration request at all.
