fix: bound the invocation list offset and keep webhook keys out of caches - #1734
Conversation
…ches `GET /automations/:id/invocations` parsed `offset` with no upper bound, so a caller could drive an arbitrarily deep OFFSET scan. The query string now goes through `parseQuery` with a zod schema: `limit` 1–100 (default 20), `offset` 0–10000 (default 0); anything else answers 400 before the store is touched, matching the audit, analytics, and automation-list routes. `POST /automations/:id/regenerate-key` returns the only copy of a freshly minted webhook key; the route now declares `cacheControl: "no-store"`. `AUTOMATION_MANAGE_POLICY` is exported so the key module extends the shared manage policy instead of restating it.

Deep code-quality review complete. I found no structural, abstraction, boundary, branching, or decomposition blockers. The invocation-list change deletes the permissive ad-hoc parser in favor of the existing parseQuery boundary, keeps validation local to the route, and adds focused boundary coverage without growing the production module materially. The webhook-key response policy is expressed declaratively at route admission and reuses the canonical automation-management policy rather than duplicating authorization details. No touched file approaches the 1k-line threshold.
Verification: diff/check and surrounding implementations reviewed; CI currently reports the control-plane unit suite, TypeScript typecheck, lint/format, and web build passing. A local focused-test attempt could not start because the detached review worktree has no installed dependencies; the equivalent control-plane unit CI job passed.

Summary
PR #1734, fix: bound the invocation list offset and keep webhook keys out of caches, by @ColeMurray changes 6 files (+107/-15). The bounded query validation and no-store response policy are well tested, but the stricter limit handling introduces a user-visible regression in the existing automation history client.
Critical Issues
- [Correctness]
packages/control-plane/src/routes/automation-runs.ts:26- Rejecting limits above 100 conflicts with the current detail page's unboundedHISTORY_PAGE_SIZE + extraHistoryLimitrequest. For histories over 100 entries, the fifth Load more click requestslimit=120and now receives a 400 instead of the previous clamped response. Update the client pagination/cap in this PR, or preserve compatible server behavior.
Suggestions
None beyond the blocking inline finding.
Nitpicks
None.
Positive Feedback
- Query validation rejects duplicate, malformed, negative, fractional, and excessive values before database reads.
- The response policy applies
Cache-Control: no-storecentrally, including non-success responses, and the conformance snapshot guards the route contract. - Focused tests pass (20/20), control-plane typechecks pass, and
git diff --checkreports no errors.
Questions
None.
Verdict
Request Changes: align the web client's Load more behavior with the new strict maximum before merging.

This new rejection conflicts with the current automation detail client: page.tsx calls useAutomationInvocations(id, HISTORY_PAGE_SIZE + extraHistoryLimit, 0) and increments extraHistoryLimit by 20 on every Load more click. When total > 100, the next click after loading 100 requests limit=120; this PR changes that request from a clamped 200 to 400 Invalid limit, and SWR can no longer load/render the requested history. Please update the client to stop at the maximum or switch it to real offset pagination as part of this contract change (or retain compatible server clamping).

Confirmed, thanks. The page grew limit by 20 per click with no ceiling, so the fifth click on a history over 100 would have gone from a silently clamped request to a 400 and an empty list.
Fixed in e201040: the ceiling now lives in shared as MAX_AUTOMATION_INVOCATION_LIST_LIMIT, the endpoint refuses past it, and the detail page clamps its request to it and withdraws "Load more" once it is reached. This keeps the effective behavior the old clamp gave (history stops at 100) while making the button honest about it. page.test.tsx clicks "Load more" until it disappears on a 150-invocation history and asserts the last request is exactly the maximum; it fails against the uncapped page (asked for 160). Real offset pagination stays a follow-up, as the existing comment in page.tsx already notes.
The detail page grew its invocation `limit` by a page per click with no ceiling; once the endpoint refuses limits above its maximum that click would get a 400 and the history would blank out. The maximum now lives in shared as `MAX_AUTOMATION_INVOCATION_LIST_LIMIT`, the endpoint refuses past it, and the page clamps its request to it and withdraws "Load more" once it is reached.

Against the old server the fifth click on a long history was a silent no-op (clamped to 100, button stayed); against the new server it would have been a 400 and a blanked list.
