Nineteen routes leave the legacy adapter: the thirteen automation routes, the Autofix activity route, and the four webhook routes (Sentry, automation webhook, GitHub event, Slack event). Each module is a Hono sub-app mounted at its catalog position, so precedence is unchanged; the webhook modules nest under one sub-app in their previous order. Policies are the ones `defineRoute(s)` declared, including the automation ownership requirement and the handler-authenticated webhook policies. Handlers take Hono's decoded params typed from the path; the automation and webhook handlers read `params.id` (and `runId`) instead of a match group, and the guards for an absent group go with the match array. `createAutomationEventRoute` becomes `createAutomationEventRoutes` and returns the module. The automation route tests dispatch every request through the production module, so admission runs: the ownership requirement is enforced by `admitRoute` rather than simulated, `HttpError`s surface as the JSON envelope the lifecycle produces, and a Slack bot actor is refused at admission with `service_capability_required` rather than reaching the handler's fail-closed branch.

Summary
PR: #1728, refactor: convert automations, autofix, and webhooks to Hono sub-apps
Author: @ColeMurray
Changes: 10 files, +277/-285
The route-module conversion preserves route order and admission policies, and the focused route, webhook, autofix, integration, and typecheck verification passed. I found one non-production test-isolation issue in the converted automation suite.
Critical Issues
None.
Suggestions
- [Testing]
packages/control-plane/src/routes/automations.test.ts:284- Initialize the automation lookup mock per test now that production admission performs this lookup; the current suite depends on retained state from earlier tests. See inline comment.
Nitpicks
None.
Positive Feedback
- Dispatching tests through the production Hono module materially improves coverage of authentication and authorization behavior.
- Shared admission middleware constants reduce repetitive policy wiring without obscuring route-specific permissions.
- Webhook sub-app composition preserves the prior registration order, and focused integration coverage passes.
Questions
None.
Verdict
Comment: The production refactor looks sound; please address the order-dependent test setup to keep individual test selection reliable.

This helper now runs requireAutomation admission, so mockStore.getById is part of the setup for manage routes. beforeEach uses vi.clearAllMocks(), which preserves mock implementations, but it does not restore getById. As a result, the full file passes because an earlier PUT test leaves sampleRow, while selecting soft-deletes automation alone fails with a 404. Please establish an explicit getById default in beforeEach (and override it in missing-automation cases), or reset and rebuild all mock defaults per test.

Confirmed and fixed in 5659765: the isolated run answered 404 exactly as described. beforeEach now sets getById to the sample row and the missing-automation cases override it to null.
Admission resolves the automation for every manage route now that the suite dispatches through the sub-app, so `getById` is part of every manage test's setup. `vi.clearAllMocks()` keeps implementations, which let an earlier PUT test's row satisfy later tests; selecting one of them alone answered 404. The default is set in `beforeEach` and the missing-automation cases override it. Claude-Session: https://claude.ai/code/session_01KdDpTgGEjXpBA9SaGQVUH1

Deep code-quality review
The Hono migration preserves behavior and reduces legacy-adapter surface, but it stops short of the structural cleanup this boundary change makes possible. The automation module remains a 1,494-line production monolith with a 1,895-line test, even though the sessions migration already demonstrates the cleaner pattern: focused route modules behind a tiny composition root. The normalized-event factory also becomes a heavier sub-app factory without becoming a sound generic abstraction, and the new route-level test fixture duplicates SQL-sensitive authorization internals instead of extending canonical test support.
A separate review already identified and reproduced the order-dependent automation test setup (soft-deletes automation passes in the full suite but fails with 404 when selected alone), so I have not duplicated that inline comment.
These are maintainability blockers rather than cosmetic nits. Please use this migration to establish focused automation modules, collapse the single-caller event factory, and centralize admission database setup before merging. No file crosses from below 1,000 lines to above it in this diff, but preserving two extreme outliers during the module conversion is still a missed decomposition opportunity.
Verification: shared package build passed; all 113 automation tests pass together; the isolated soft-deletes automation test fails as described above.

[deep review] This conversion leaves all 13 endpoints in a 1,494-line route file (with a 1,895-line companion test). That is more than twice the next-largest production route file, and it misses the code-judo move already established by sessions.ts: a tiny composition root over responsibility-focused modules. The route set naturally separates into CRUD/listing, lifecycle/triggering, runs, secrets, and Slack integration settings. Can we decompose this before cementing the Hono boundary rather than preserving the monolith behind one larger sub-app?
There was a problem hiding this comment.
Agreed the file is an outlier, but it predates this PR (1,527 lines on main; this diff shrinks it), and splitting 13 routes across five modules inside a conversion diff would bury the behavior-preserving changes under file moves. I'd rather land the decomposition as its own moves-only PR right after this series, mirroring the sessions layout, so each diff stays reviewable for what it is. I'll open it once the shim-removal PR merges.

[deep review] This abstraction is generic in path and AutomationEventSource, but its admission policy is unconditionally serviceAuthorized("slack-bot"), and Slack is its only caller. Returning an entire Hono sub-app makes the single-caller wrapper heavier without making its contract truthful; another source would compile with the wrong authorization. The simpler structure is to register the Slack route directly in slack.ts and keep only the genuinely shared validation/forwarding functions here (or, if multiple callers are imminent, make the service policy source-correlated and explicit).

Done in 59e0834. The factory is gone; slack.ts registers its route under its own serviceAuthorized("slack-bot") policy and composes the exported validate-and-forward steps, exactly as github.ts does. Only the shared steps remain in automation-event.ts.

[deep review] This feature-local fixture now recognizes authorization by literal SQL fragments and reconstructs role/permission rows, duplicating the same query-sensitive knowledge already centralized in ownerAuthorizationDatabase in router.test-support.ts. That duplication adds another maintenance point to an already 1,895-line suite: any authorization-query change can silently break fixtures independently. Please extend the canonical helper with permissions/batch/fallback-statement options and reuse it here rather than embedding admission SQL internals in the automation tests.

Done in 59e0834. router.test-support.ts now owns authorizationDatabase({ userId, permissions, statement, batch }), which recognizes admission's two lookups in one place; ownerAuthorizationDatabase() is the owner shortcut over it. The automations suite passes its statement spy and batch mock through and carries no SQL knowledge of its own.
…rization fixture Review follow-ups. The normalized-event factory was generic over the event source but admitted every caller as the Slack bot, and Slack was its only caller. The Slack route now registers itself the way the GitHub route does, composing the exported validation and forwarding steps under its own service policy; the factory is gone. Test support gains `authorizationDatabase(options)`: admission's two lookups (the user's role, a custom role's grants) are recognized in one place, with the remaining statements and `batch` handed to the suite. `ownerAuthorizationDatabase()` is the owner shortcut over it, and the automations suite no longer carries its own copy of that SQL knowledge.

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 opened as #1733: |
Follow-up promised on #1728: the deep review asked for focused automation modules behind a tiny composition root, and we agreed to land it as a moves-only PR once the Hono series finished (#1730 merged). **Moves only.** No behavior, policy, message, or logic changes; no renames beyond what a move requires. `routes/catalog.ts` still imports `automationRoutes` from `./automations`, which now mounts the modules below in the previous registration order, so route precedence is unchanged. | File | Routes | Lines | |---|---|---| | `automations.ts` | composition root | 24 | | `automation-slack-settings.ts` | 2 | 85 | | `automation-list.ts` | 1 | 149 | | `automation-crud.ts` | 4 | 682 | | `automation-lifecycle.ts` | 3 | 178 | | `automation-runs.ts` | 2 | 64 | | `automation-keys.ts` | 1 | 102 | | `automation-validation.ts` | helpers | 344 | | `automation-shared.ts` | admission | 27 | Shared pieces: `automation-validation.ts` holds the request validation and target-selection helpers that create and update both use; `automation-shared.ts` holds the two `admit()` constants and the admitted-automation accessor. Each module keeps its own `createLogger("router:automations")`, so log output is identical. **Tests** split the same way, one suite per module, each dispatching through its own sub-app via `createTestRequestHandler([module])`: | File | Suites | Lines | |---|---|---| | `automation-list.test.ts` | list | 151 | | `automation-create.test.ts` | create | 760 | | `automation-update.test.ts` | get, update, delete | 759 | | `automation-lifecycle.test.ts` | pause, resume, trigger | 220 | | `automation-runs.test.ts` | invocations, run | 135 | | `automation-keys.test.ts` | regenerate-key | 106 | | `automations.test-support.ts` | store doubles, request builder, sample row, mock defaults | 219 | Create and update are separate files so neither passes 1,000 lines. All 113 tests are kept with their names and intent. `vi.mock` declarations are per file by construction (Vitest hoists them per module), and each suite declares only the mocks its module reaches; the doubles they hand out are shared. ## Verification | Check | Result | |---|---| | Typecheck (src, test, integration) | clean | | ESLint, Prettier | clean | | Unit | 239 files, 3,511 passed (113 automation tests across 6 files) | | Integration (workerd, real D1) | 96 files, 1,129 passed | | Matrix and conformance snapshots | byte-identical | | Largest file in the diff | `automation-create.test.ts`, under 1,000 lines | https://claude.ai/code/session_01KdDpTgGEjXpBA9SaGQVUH1 <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added comprehensive automation management, including creation, editing, deletion, pausing, resuming, and manual triggering. * Added automation listing with search, repository filtering, pagination, and recent execution details. * Added access to automation runs and invocation history. * Added webhook and Sentry credential regeneration. * Added Slack channel configuration endpoints. * Added validation for schedules, triggers, targets, providers, environments, permissions, and Slack conditions. * **Refactor** * Organized automation functionality into dedicated areas while preserving the existing automation API. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
