official actions/checkout documentation persist-credentials default GITHUB_TOKEN pull_request fork permissions
💡 Result:
<search_synthesis>
The actions/checkout action uses persist-credentials: true by default [1][2]. When enabled, this configuration stores the authentication token (e.g., GITHUB_TOKEN) in the local Git configuration (.git/config or a temporary file in $RUNNER_TEMP in recent versions), allowing subsequent steps in the workflow to perform authenticated Git operations [3][2]. For pull requests originating from forks, the following security and permission behaviors apply: 1. GITHUB_TOKEN Permissions: By design, workflows triggered by a pull_request event from a fork receive a read-only GITHUB_TOKEN to prevent untrusted code from modifying the base repository [4][5]. 2. Checkout Security: To prevent "pwn request" vulnerabilities, actions/checkout v7 and later refuses to check out fork pull request code when using the pull_request_target or workflow_run triggers by default [3][6]. 3. Security Guidance: If you do not require authenticated Git commands in your workflow, it is recommended to set persist-credentials: false to avoid unnecessarily exposing the token to the environment [7][8]. This is particularly important when running code that may execute untrusted commands [8]. For trusted write operations involving forks (e.g., labeling or commenting), it is recommended to move these tasks to a workflow_run triggered job or a carefully configured pull_request_target job, rather than attempting them in the untrusted context of a pull_request job triggered by a fork [5]. Top results: [3], [6], [4], [5]

Do not persist the checkout token in the engine-tests job.
This pull_request job runs repository-controlled materialization and typecheck commands. The default checkout persists the token for authenticated Git commands, so untrusted code can read and exfiltrate it. Set persist-credentials: false and restrict this job to contents: read.

Preserve the typecheck exit status.
The opencode typecheck script runs tsgo --noEmit. The gate does not enable set -e, so it ignores the nonzero status from bun run typecheck. If the command prints the tsgo --noEmit banner, exits nonzero, and emits no error TS line, the banner check passes, UNEXPECTED remains empty, and the gate reports success.
Capture the status and fail unless the nonzero result is explained by the existing allowlisted diagnostics.

The fork-absorption (#1114) moved the opencode engine into the overlay but left it with NO CI test/typecheck coverage: packages/app-bundle/overlay/ packages/opencode is not a pnpm workspace member (pnpm-workspace.yaml globs packages/* non-recursively), so the `fast` job's `pnpm -r run typecheck` skips it. The fork ran `bun turbo typecheck`/`bun turbo test`; the cutover (S4 #1111) never ported them. Engine type regressions have merged unseen. This restores the engine typecheck as a standalone `engine-tests` CI job (materialize the full tree -> bun install -> opencode typecheck), the fork's typecheck.yml scoped to the engine. Green-up (pre-existing errors on dev the gate caught): - src/session/lineage.ts: `.filter((id): id is string ...)` must narrow to `id is SessionID` (the branded column type); 4 cascading errors cleared. - test/session/prompt.test.ts: MCP mock omitted `remove`, now required by the overlaid MCP.Interface — add `remove: () => Effect.void`. - test/provider/transform.test.ts: cast content elements `as any` before reading `.type` (matches this file's own convention at :3138) — the Part-union widening from a recent dev merge left these two assertions behind. Three remaining typecheck errors are a base-pin drift (manifest upstream_base_sha=7fe9938 predates the base the overlay was authored against): allowlisted in the gate script by file+rule, tracked in #1229. New errors outside the allowlist fail CI (verified: injected error reds; allowlisted-only passes). The gate is fail-closed (reds if tsgo did not execute). Also: `pnpm test:engine` local entrypoint + AGENTS.md verification-gates row. manifest.json refreshed for the overlay edits (drift_gate PASS). Deferred, tracked: - #1229 base-pin bump -> unlocks full-monorepo typecheck (ui/app also drift). - #1233 engine unit-TEST lane (bun turbo test + test:httpapi) -> blocked on real amicode test fixes (amicode-connections.test.ts failures + hook-timeout slowness).

- Restrict engine-tests to contents: read and disable persisted checkout credentials before executing materialized PR code. - Capture bun typecheck exit status; fail closed when it exits nonzero without TypeScript diagnostics, while still allowing only the #1229 baseline errors. Reviewed by CodeRabbit; verified locally with the real allowlisted path and a synthetic non-diagnostic bun failure (exit 1).

…t lane (#1233) Restore the final #1233 state cleanly on main after #1235 merged: - fix the connections-suite hang by redirecting every token credential path (AMICO_SLACK/GITHUB/LINEAR/GOOGLE/GOOGLE_DRIVE_FILE) into each test tmpdir; real ~/.amico credentials no longer leak a second background revalidation. - quarantine the one legacy-lineage spec conflict (it.instance.skip, #1239), leaving the other 22 session tests active. - add engine_test_gate.sh plus `pnpm test:engine:unit` / AGENTS.md docs. - run the unit suite after the required typecheck gate as a non-blocking CI lane. The suite reports on every main PR; promote it to required after #1239 hardens pollution, timing flakiness, and positive cross-test dependencies. - preserve #1235's contents:read and persist-credentials:false security hardening and main-only CI trigger. The runtime base-drift recorded test remains excluded under #1229. Refs #1233, #1239, #1229

Narrow each allowlist entry to one known diagnostic.
The current pattern suppresses every matching error code in each listed file. A new TS2322, TS2339, or TS2741 error in an allowlisted file makes UNEXPECTED empty and lets CI pass.
Match a stable diagnostic-message fragment for each known error, or assert an exact expected diagnostic count per fingerprint.

Restore engine typecheck CI coverage — Slice A + gate (#1228)
What this does
The fork-absorption (#1114) moved the opencode engine into the overlay but left
it with no CI test/typecheck coverage —
packages/app-bundle/overlay/packages/opencodeis not a pnpm workspace member (
pnpm-workspace.yamlglobspackages/*non-recursively), so the
fastjob'spnpm -r run typechecksilently skips it.The fork ran
bun turbo typecheck; the cutover (S4 #1111) never ported it.Engine type regressions have merged unseen.
This PR restores the engine typecheck as a standalone
engine-testsCI job andfixes the two real, dev-resident type errors it immediately caught.
Changes
engine-testsjob (ci.yml): materialize the full engine tree →bun install→ opencode package typecheck via
packages/app-bundle/scripts/engine_typecheck_gate.sh.New type errors fail CI; the gate is fail-closed (reds if
tsgodidn't run).dev):src/session/lineage.ts—.filter((id): id is string ...)narrowed toid is SessionID(the branded column type); 4 cascading errors cleared.test/session/prompt.test.ts— MCP mock was missingremove, now required bythe overlaid
MCP.Interface.pnpm test:enginelocal entrypoint + anAGENTS.mdverification-gates row.manifest.jsonrefreshed for the two overlay edits (drift_gatePASS).Base-drift allowlist (tracked in #1229)
Three remaining opencode typecheck errors are a base-pin drift: manifest
upstream_base_sha=7fe9938predates the base the overlay was authored against, sotest/server/httpapi-mcp-oauth.test.ts,test/session/llm-native-recorded.test.ts,and
test/session/snapshot-tool-race.test.tsreference symbols (MCPremove,promptAgnosticMatcher) absent from the stale base. They're allowlisted in thegate script by file+rule and tracked in #1229 (which bumps the base and deletes
the allowlist).
Verification
