refactor: convert the first route modules to Hono sub-apps - #1723
Merged
Conversation
Health, keyboard shortcuts, model preferences, sign-in providers, audit events, and analytics register natively with Hono behind admit(policy) and read the admitted request and context from the Hono context. The catalog mounts a module where it appears and keeps registering legacy routes through the adapter, so precedence is unchanged. Route contracts for the policy tests and boundary suites are read from Hono's own route list rather than the catalog array. Claude-Session: https://claude.ai/code/session_01KdDpTgGEjXpBA9SaGQVUH1

This conversion reduces route-module boilerplate, but the new module boundary does not enforce its central security invariant. An arbitrary Hono app is accepted as a RouteModule; unadmitted handlers can execute before the response-time guard runs, and contract enumeration then hides those handlers from the policy and admission suites. Because this is the pattern intended for the remaining 159 routes, the boundary needs to make policy-plus-handler registration atomic or validate the complete route stack before mounting.
CI is green and no changed file crosses the 1,000-line threshold, but those checks do not cover this fail-open execution path. Requesting changes on the structural admission issue below.

A module is mounted only if every route it registers has admit() as its first handler and it registers no middleware of its own, so a handler can never run ahead of admission.

## Summary Fourth step of the series retiring the routing adapter (#1720, #1721, #1723). This PR converts the sessions cluster, the largest and most policy-diverse group, to native Hono sub-apps: 42 routes across 13 session modules plus the Slack notification route. It is the design proof for path parameters and for the sandbox-fallback and exact-sandbox policies. **Modules.** Each session module is a `Hono` sub-app registering `admit(policy)` first, and `sessions.ts` nests them under one sub-app in the old precedence order (`/sessions/inbox` still registers before `/sessions/:id`). The catalog mounts that sub-app and the Slack notification module where the spread and the inline route used to sit. **Handlers** keep their bodies and take a typed params object in place of the match array: ```ts export async function handleGetChild( request: Request, env: Env, params: { id: string; childId: string }, ctx: SessionRouteContext ): Promise<Response> ``` Registration passes `c.req.param()`, which Hono types from the path literal, so a handler declaring `childId` cannot be wired to a route without one. `withSessionRuntime(env, ctx)` replaces the `sessionRoute()` wrapper: it attaches the runtime client at the call site, and the handler-level tests use the same function to build their context. **Runtime proxy.** The three factories (`simpleProxy`, `legacyTokenRefresh`, `lifecycleProxy`) now build handlers rather than catalog entries, collected in `sessionRuntimeProxyHandlers` and registered one route each. The tests select handlers from that map by the production contract instead of scanning a route array. **Decode once, in Hono.** Admission now reads `c.req.param()`, so the session id the sandbox binding verifies, the automation id the ownership check loads, and any actorless-grant path parameter are Hono's decoded values, and admission's own `decodeURIComponent` calls are removed. `rawRouteParams` survives only inside the legacy adapter, for the modules not yet converted, and goes with them. ## Behavior change An encoded session id now resolves the same session as its plain form: `GET /sessions/%74est-…` returns the session rather than 404, and a sandbox token on `/sessions/%74est-…/tunnel-urls` verifies rather than 401. The guardrail tests from #1720 record this as their new expectation. No other route observed a different status: both integration snapshots are byte-identical to `main`. ## Tests Handler-level tests pass params objects and get their session runtime from `withSessionRuntime`; assertions are unchanged. `router.create-session.test.ts` calls the exported `handleCreateSession` directly. No test lost coverage; the route-matrix suite covers every converted route per credential class as before. ## Verification - Unit: 234 files, 3,476 passed. - Integration (workerd, real D1): 96 files, 1,128 passed. Route-matrix and conformance snapshots unchanged. - Typecheck (`src`, `tsconfig.test.json`, `test/integration`), ESLint, and Prettier clean. ## Review follow-up (71224c4) - **Malformed path segments are refused at admission.** Hono leaves a segment it cannot decode as it arrived, so the automation-id requirement's 400 had become a 404. `admit()` now checks every raw `:param` segment once and answers `400 { error: "Invalid path encoding" }` on every route before any lookup. This replaces the three route-specific messages `main` produced for this input (`Invalid automation route`, `Invalid user ID` on malformed member ids, and the session routes' 404); the two RBAC integration expectations and the routing-compatibility probe record the uniform envelope. Both matrix snapshots are still byte-identical. - **One call-site adapter.** `dispatch(c, handler)` in `routing/admit.ts` is the only place a Hono context is unpacked for a handler; `dispatchSession(c, handler)` adds the runtime client. A route reads `admit(policy), (c) => dispatchSession(c, handleX)`. The context type is checked against the policy, so a user-only handler behind a user-or-service policy fails to compile (a curried `handle(handler)` form was tried and rejected because Hono infers the environment from the returned function and that check disappears). - **Proxy tests dispatch through the production sub-app.** The test-only handler map is gone; the runtime proxy registers its handlers directly, and `session-runtime-proxy.test.ts` sends real requests through `sessionRuntimeProxyRoutes`, with a 17-row wiring table that fails if a route is bound to the wrong proxy. https://claude.ai/code/session_01KdDpTgGEjXpBA9SaGQVUH1 <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Improvements** * Standardized routing and authorization across session, attachment, media, child-session, prompt, pull-request, skills, WebSocket token, and notification endpoints. * Preserved existing endpoint paths, permissions, upload validation, streaming, and error handling. * Improved handling of percent-encoded path values so valid requests resolve correctly. * **Bug Fixes** * Malformed percent-encoded path segments now return a clear 400 error before processing. * **Tests** * Expanded coverage for routing, authorization, encoded paths, and request dispatch. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

Last PR of the Hono series (#1720, #1721, #1723, #1724, #1726, #1727, #1728, #1729). Every route module is a Hono sub-app, so the adapter that carried catalog routes through admission has nothing left to serve. ## Removed - `legacy()` and `legacyMatch()` in `routing/hono-app.ts`; `createControlPlaneApp(modules, host)` mounts modules only. - `RouteDefinition`, `Route`, `defineRoute()`, `defineRoutes()`, and `extractRepoParams()` in `routes/shared.ts`. `RouteAdmissionPolicy` is now an interface over `RoutePolicy` plus `authorization` and `serviceActorClaims`; `cacheControl` lives on `AdmissionPolicy` in `routing/admit.ts`. - `RouteCatalogEntry`; the catalog is `readonly RouteModule[]`. - `legacyRoutes()` in test support; `matchRoute()` no longer fabricates a `RegExpMatchArray`. - `routes/shared.test.ts`, replaced by `routes/repository-params.test.ts` over the decoded pair. ## Kept on purpose - `RouteParams`: admission's decoded-parameter dictionary. Hono exports no such type. - `rawRouteParams()`: the malformed-encoding guard's raw read-back (added in #1724). ## Tests Fixtures that need synthetic routes build a `Hono` module and pass it to `createTestRequestHandler([module])`: the lifecycle suite, the contract lister's suite, and the authorization-audit suite's eleven routes. The two Worker-boundary suites build their shadow catalogs the same way: conformance echoes the raw read-back through `rawRouteParams()`, and the matrix's "raw path segments" probe from #1720 is now the decode-once assertion on what handlers receive (`abc%2Fdef` arrives as `abc/def`, `web%252Fapp` as `web%2Fapp`). ## Verification | Check | Result | |---|---| | Typecheck (src, test, integration) | clean | | ESLint, Prettier | clean | | Unit | 234 files, 3,512 passed | | Integration (workerd, real D1) | 96 files, 1,129 passed | | Matrix and conformance snapshots | byte-identical | https://claude.ai/code/session_01KdDpTgGEjXpBA9SaGQVUH1 <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **Bug Fixes** - Repository paths now support nested owner namespaces, such as `group/subgroup`. - Repository names containing slash characters are rejected with a clear validation message. - URL path parameters are decoded consistently, improving handling of encoded repository and member identifiers. - **Refactor** - Control-plane routing now uses the current route-module system, providing consistent admission, route matching, and request handling behavior. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

Follow-up agreed in the #1723 review discussion: the hand-rolled `searchParams` parsing in the audit-events and analytics routes becomes Zod schemas over the query string. ## The helper `parseQuery(request, schema)` in `routes/query.ts`: - reads only the keys the `z.object` schema declares, so unrelated query keys are ignored as before; - refuses a declared key given more than once as `400 { error: "Invalid <key>" }` before the schema runs, the rule `singleQueryValue` applied in audit events; - answers a schema failure with its first issue's message, so each route keeps its own wording. ## Messages preserved | Route | Input | Response | |---|---|---| | `GET /audit-events` | limit not `/^[1-9]\d*$/`, unsafe, or over 100 | `Invalid limit` | | `GET /audit-events` | cursor that does not parse | `Invalid cursor` | | `GET /audit-events` | repeated `limit` / `cursor` | `Invalid limit` / `Invalid cursor` | | `GET /analytics/*` | days not in 7, 14, 30, 90 (read with `Number()` as before) | `days must be one of: 7, 14, 30, 90` | | `GET /analytics/breakdown` | `by` missing, empty, or unknown | `by must be one of: user, repo` | Defaults are unchanged (limit 25, days 30). Regexes and `.transform(Number)` are kept rather than `z.coerce`, per the discussion. ## One deliberate change An analytics key given twice (`?days=7&days=14`) used to take the first value silently; it now answers `400 Invalid days`, the same rule audit events already enforced. No other input changes outcome. ## Tests - `routes/query.test.ts`: helper contract (declared keys only, duplicate refusal, first-issue message). - `routes/audit-events.test.ts` (new, request-level): default, maximum, cursor round-trip, nine invalid limits, four invalid cursors, repeated keys, issue ordering. - `routes/analytics.test.ts`: every accepted window, five rejected windows, repeated keys, empty `by`, issue ordering. ## Verification | Check | Result | |---|---| | Typecheck (src, test, integration) | clean | | ESLint, Prettier | clean | | Unit | 236 files, 3,546 passed | | Integration (workerd, real D1) | 96 files, 1,129 passed | | Matrix and conformance snapshots | byte-identical | https://claude.ai/code/session_01KdDpTgGEjXpBA9SaGQVUH1 <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Improved analytics query validation for supported reporting windows and breakdown options, including clearer handling of invalid or repeated values. * Improved audit-event filtering and cursor pagination validation, including limits, invalid cursors, and duplicate parameters. * Standardized query validation across supported routes, including automation listings, so invalid requests are rejected consistently with clearer error messages. * **Tests** * Added comprehensive coverage for valid, invalid, repeated, empty, and conflicting query parameters across analytics, audit-event, automation, and shared query handling. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

Follow-up to CodeRabbit's open thread on #1723, which asked for a cache policy on `GET /keyboard-shortcuts`. That was deferred as a behavior change needing its own reviewed diff; this is that diff. ## Routes changed Each now declares `cacheControl: "private, no-store"` in its `admit()` policy, so the lifecycle stamps `Cache-Control: private, no-store` on the response: - `GET /keyboard-shortcuts` (`routes/keyboard-shortcuts.ts`): the caller's own shortcut bindings. - `GET /model-preferences` (`routes/model-preferences.ts`): the enabled-model preference. Workspace-scoped rather than per-user, but a mutable settings read that the web client and the Slack bot fetch on demand; same treatment as `GET /audit-events`, which already declares the policy for workspace data. - `GET /skill-profiles` (`routes/skills.ts`): the caller's own skill profiles. A separate `PROFILES_READ_OWN` admit constant carries the policy so the writes sharing `PROFILES_MANAGE_OWN` are untouched. ## Considered and excluded - `GET /me/authorization` and the model-provider-account reads: already declare `private, no-store`. - `GET /skills`, `GET /skills/:id`: the installation's managed skill catalog, shared workspace data. - Session, repository, automation, and analytics reads: shared workspace data, out of scope for a preference policy. - No `/me/...` preference routes exist beyond the authorization read. ## Tests `keyboard-shortcuts.test.ts` (new), `model-preferences.test.ts` (new), `skills.test.ts` (new): each dispatches through its production module with the mocked-`authenticate` and owner-database recipe and asserts the header on the read; the keyboard-shortcuts suite also asserts the write declares none. ## Snapshot `hono-route-catalog-conformance.test.ts.snap` changes on exactly three rows (`cacheControl` for the routes above). The admission matrix snapshots are unchanged. ## Verification | Check | Result | |---|---| | Typecheck (src, test, integration) | clean | | ESLint, Prettier | clean | | Unit | 3,515 passed | | Integration (workerd, real D1) | 96 files, 1,129 passed | https://claude.ai/code/session_01KdDpTgGEjXpBA9SaGQVUH1 <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Prevented caching of keyboard shortcut, model preference, and skill profile responses to help keep personal settings and data private. * Updated the model preferences API to consistently handle reading and saving preferences while preserving session-based access and response handling. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

Summary
Third step of the series retiring the routing adapter (#1720 guardrails, #1721 mechanism). This PR converts the first six route modules to native Hono sub-apps and establishes the pattern the remaining module PRs follow. 12 routes convert; the other 159 still go through the catalog adapter.
A converted module is a
Honosub-app whose routes register withadmit(policy)as their first middleware and a native handler behind it:admit()is now generic over its policy and setsc.var.admittedas{ request, ctx }, whererequestis the request as authentication returned it (sig1 verification consumes the original body) andctxis the request context narrowed by the policy's authentication kind, exactly asRouteContext<Authentication>narrowed the legacy handler's fourth argument. Handlers usec.req.param()for path parameters; none of the six modules has one, so no decoding question arises in this PR.The catalog mounts modules in place.
catalog(renamed fromroutes) is an ordered list ofRoute | RouteModule.createControlPlaneAppmounts a sub-app withapp.route("/", module)where it appears and registers a legacy route through the adapter where it appears, so registration order, and therefore precedence, is unchanged. The path grammar and duplicate-parameter checks run for module routes too.Route contracts come from Hono's own route list.
listRouteContracts(app)walksapp.routesand yields{ method, path, ...policy }for every entry whose handler is theadmit()middleware, which carries the policy it enforces. The policy tests, the route-admission matrix, its sentinel suite, and the conformance suite iterate that list instead of the catalog array, so they cover converted and legacy routes alike. Both integration snapshots are byte-identical tomain.Handler-level tests become request-level.
analytics.test.tswent throughcreateTestRequestHandler([analyticsRoutes])withauthenticatemocked to return a user andownerAuthorizationDatabase()answering the effective-authorization lookup, which is the patternrouter.authorization-audit.test.tsalready used. Same assertions, plus a denial case that proves no store is touched. The remaining 26 handler-level test files convert with their modules.Converted:
