Reviewed via Impeccable harden + audit modes (change type: bug_fix, since this PR fixes a cache-integrity bug and touches a schema constraint).
Test change (logs_cached_json_live_integration_test.go) — solid addition: it verifies each cached run ID appears in exactly one JSONL shard and that shards contain only the queried runs, directly covering the "duplicate run records across shards" bug described in the PR body. No issues found here.
Schema change (github-workflow.json) — left one comment: pkg/workflow/schemas/github-workflow.json is a generated/patched file (see make download-github-actions-schema + make patch-github-actions-schema in the Makefile). The patch-github-actions-schema jq script doesn't currently patch id-token, so this hand-edit will be silently lost on the next schema refresh. Worth either wiring the fix into the Makefile patch step or confirming this file is no longer auto-regenerated.

This manual edit to the SchemaStore-derived id-token definition is unrelated to the PR's stated purpose (cached run/shard validation) and, more importantly, this file is regenerated by make download-github-actions-schema + make patch-github-actions-schema. The patch-github-actions-schema jq script in the Makefile only appends missing properties (copilot-requests, drives, vulnerability-alerts) — it does not override the existing id-token $ref. So the next time someone runs make download-github-actions-schema, this fix will silently be dropped and id-token will revert to $ref: "#/definitions/permissions-level" (allowing read, which GitHub Actions doesn't actually support for id-token).
Please either:
- Revert this hand-edit and instead add an override for
id-tokento thepatch-github-actions-schemajq command in the Makefile (mirroring howdrives/copilot-requestsare patched), so the fix survives regeneration, or - If this file isn't actually regenerated in CI/dev workflows anymore, drop the Makefile targets so they don't silently overwrite this.
@copilot please address this.

Skills-Based Review 🧠
Applied /tdd and /codebase-design — requesting changes on durability and test-coverage gaps.
📋 Key Themes & Highlights
Key Themes
- Schema regeneration risk: the
id-tokenfix inpkg/workflow/schemas/github-workflow.jsonis a manual edit to a file that is normally regenerated bymake download-github-actions-schema+patch-github-actions-schema. Without adding it to the Makefile'sjqpatch expression alongsidecopilot-requests/drives/vulnerability-alerts, this fix will be silently lost on the next schema refresh. - Regression test only runs with live GitHub auth: the new "each run appears in exactly one shard" assertion lives in
(go/redacted):build integrationTestLogsCachedJSONLLiveCaching, which self-skips withoutgh auth. A fast, synthetic-data unit test alongside the existing ones inlogs_cached_json_test.gowould give this invariant real CI coverage.
Positive Highlights
- ✅ Good instinct to add an explicit invariant check (uniqueness across shards) rather than just asserting aggregate counts.
- ✅ Tightening
id-tokento["write", "none"]correctly reflects that GitHub Actions doesn't supportid-token: read(matches existingidtoken_write_warning_test.gobehavior).
@copilot please address the review comments above.

[/codebase-design] This hand-edits the vendored schema file directly, bypassing the established patch-github-actions-schema mechanism (Makefile) used for every other custom permission override (copilot-requests, drives, vulnerability-alerts). Since github-workflow.json is regenerated by make download-github-actions-schema + patch-github-actions-schema, this id-token fix will be silently clobbered back to the generic $ref: permissions-level (allowing invalid read) the next time someone regenerates the schema.
💡 Suggested fix
Add the id-token override to the jq patch expression in Makefile's patch-github-actions-schema target, alongside the existing entries for copilot-requests/drives/vulnerability-alerts, e.g.:
.definitions["permissions-event"].properties += {
"id-token": {"type": "string", "enum": ["write", "none"]},
"copilot-requests": {...},
...
}This keeps the fix durable across regenerations instead of only living in the currently-checked-in snapshot.
@copilot please address this.

[/tdd] This regression test lives only in TestLogsCachedJSONLLiveCaching, which is gated behind (go/redacted):build integration and skips itself unless gh auth status succeeds — so it won't run in normal unit CI and gives no fast feedback loop for this invariant. pkg/cli/logs_cached_json_test.go already has synthetic-data unit tests for shard merging (e.g. TestPrepareCachedLogsJSONLWildcardLoadsMatchingFilesAndWritesUniqueFile), so the "no run duplicated across shards" invariant is easy to express there too.
💡 Suggested unit test
Add a fast unit test in logs_cached_json_test.go that writes two synthetic JSONL shard files containing the same run_id and asserts either that loadCachedLogsJSONLFiles logs/handles the duplicate deterministically, or (better) add a dedicated helper that walks shards with visitCachedLogsJSONLRecords and fails if a run ID appears in more than one shard — mirroring the logic added here but without requiring live GitHub auth. This would catch regressions on every PR, not just when the integration test happens to run.
@copilot please address this.
