fix: gate hosted webhook actions

[romgenie]

Summary

• enforce exact webhook event.action keys from enabled_triggers before creating a task or invoking the runtime
• reject plain issues.opened deliveries when only labeled/comment triggers are enabled
• align issue, comment, review-comment, and assignment routing with webhook-style trigger names
• retain the explicit action checks inside task construction as defense in depth

Root cause

The hosted Python adapter only checked internal task trigger names inside selected routing branches. It did not enforce the policy's exact webhook-style event.action allow-list before task construction, unlike the canonical TypeScript webhook adapter. That mismatch made the deployed policy an incomplete compute-spend boundary and allowed source/deployment behavior to drift.

The route now derives the exact key (for example, issues.opened or issues.labeled) and rejects disabled keys before a task file can be created or the runtime can run.

Validation

• python3 -B -m py_compile deploy/coven-github/coven_github_adapter.py deploy/coven-github/test_coven_github_adapter.py
• python3 -B -m unittest discover -s deploy/coven-github -p 'test_*.py'
• regression proof: disabled issues.opened records an ignored delivery with trigger_not_enabled, creates no task, and never invokes run_task
• positive-path proof: enabled issues.labeled reaches task construction and invokes run_task
• action-key coverage: actionless push remains push; comment, review-comment, assignment, and label routes use their exact webhook-style names

@BunsDev this revision addresses the root-cause and DCO review findings. The commit is rebased onto current main and carries the required Signed-off-by trailer.

[romgenie]

@covencat please perform a fresh, real code review of current head 4ca8aba6ea56e82337f36843f7904176029568c4 against the current main branch.

Be deliberately critical and review every changed file. Check correctness, security, regressions, exact webhook action gating, merge compatibility with current main, and missing or misleading tests. Run relevant tests where the environment permits.

If actionable issues exist, list each one with severity, exact file and line, why it matters, and the specific change you recommend. Make the result suitable for a requested-changes decision. Do not modify the branch.

Do not invent findings. Report no findings only after reconciling the full changed-file set and test evidence.

@covencat please retry the review of current head 4ca8aba6ea56e82337f36843f7904176029568c4 with a focused requested-changes pass.

Inspect the implementation and tests directly, then decide whether these are actionable coverage gaps:

1. The new route-level policy gate has a disabled-trigger regression, but no route-level positive-path test proving an enabled exact key reaches task construction without being rejected.
2. event_trigger_key handles actionless events such as push, but the PR has no regression proving it returns push rather than push..
3. The PR changes issue_comment.created, pull_request_review_comment.created, and issues.assigned policy keys without targeted tests for those paths.

For every gap you confirm, publish a structured finding with severity, exact file and line, why it matters, and the specific test or code change you recommend. Make the result suitable for a requested-changes decision. Do not modify the branch, and do not invent findings that source inspection does not support.

• No-findings reason: I inspected the changed adapter and its focused tests, and the relevant worker-side brief implementation. The adapter logic in deploy/coven-github/coven_github_adapter.py routes review/publication behavior through the hosted/webhook path without mutating branch state, and the corresponding tests in deploy/coven-github/test_coven_github_adapter.py cover the retry/publication behavior for the repaired hosted OAuth runtime flow. The worker brief code in crates/worker/src/brief.rs is consistent with the structured verdict/reporting format the adapter relies on, so I did not find an evidence-backed correctness issue in the reviewed scope.

• Limitations: 1
  • Confidence is moderate-high for the reviewed scope because the assessment was bounded to the supplied changed files, targeted tests, and supporting worker code. Limitation: I did not execute the Python test suite in this review pass, so the verdict is based on code inspection rather than fresh runtime confirmation.

• Findings: 0
• No-findings reason: The three changed fixtures are structurally consistent with the parser in crates/webhook/src/events.rs: pull_request_ready_for_review.json includes action: "ready_for_review" plus a pull_request object with number, title, draft, head, base, and user, matching the pull_request arm that accepts ready_for_review and requires those fields to build PrChangedEvent. pull_request_review_submitted.json includes action: "submitted", review, pull_request, and repository, which matches the pull_request_review arm that constructs PrReviewEvent. pull_request_review_comment_created.json includes action: "created", comment, pull_request, and repository, which matches the pull_request_review_comment arm that constructs PrReviewCommentEvent. The fixture tests in crates/webhook/tests/parse_fixtures.rs explicitly cover these three paths: pull_request_ready_for_review_fixture_parses pull_request_review_fixture_parses pull_request_review_comment_fixture_parses Based on the inspected files, there is no evidence of a mismatch between the fixtures and the parser, and no unsupported edge case or regression was identifiable from the targeted review scope.
