+# Scratchpad: t_301e4e3b pr-merge.sh Gitea empty-uid fallback
+
+## Task
+
+Implement a narrow hardening in `packages/mosaic/framework/tools/git/pr-merge.sh` so Gitea merges recover from the known non-interactive `tea pr merge` identity failure: `user does not exist [uid: 0, name: ]`.
+
+## Constraints
+
+- Preserve Mosaic policy gates: squash-only, base branch `main`, queue guard unless explicitly skipped.
+- Preserve the existing authenticated Gitea API fallback when no tea login exists.
+- Do not fallback on arbitrary tea failures.
+- Do not expose tokens or credential-bearing remotes.
+- Scope is limited to the merge wrapper plus focused test/support/scratchpad files.
+
+## External issue
+
+- Gitea issue #520: Harden pr-merge.sh Gitea empty-uid fallback
+
+## Plan
+
+1. Add a focused shell regression harness with mocked `tea` and `curl` proving the known empty uid/name failure must fall back to Gitea API.
+2. Watch the harness fail on current code.
+3. Implement helper functions in `pr-merge.sh` for redacted command display, known failure classification, and authenticated Gitea API merge fallback.
+4. Keep unknown `tea` failures blocking by replaying stderr and exiting non-zero.
+5. Run syntax, shellcheck if available, focused regression, and repo quality gates before push/PR.
+
+## Session log
+
+- 2026-05-22: Read Kanban context, Mosaic global/repo instructions, created isolated branch `fix/t_301e4e3b-pr-merge-gitea-empty-uid`, and opened Gitea issue #520 using the Mosaic issue wrapper/API fallback.
+- 2026-05-22: Added regression harness and watched it fail on current behavior with `user does not exist [uid: 0, name: ]`; implemented narrow fallback and verified known-empty-identity fallback, arbitrary tea failure blocking, and no-tea-login API fallback paths.
+- 2026-05-22: Validation passed for `bash -n`, `shellcheck -x`, focused shell harness, `pnpm typecheck`, `pnpm lint`, `pnpm format:check`, and `pnpm --filter @mosaicstack/mosaic test`. Full `pnpm test` exposed an out-of-scope gateway DB setup failure (`relation "messages" does not exist`) in `apps/gateway/src/__tests__/cross-user-isolation.test.ts`.

+# t_5aab9cc8 — pr-merge.sh eval injection remediation
+
+## Objective
+
+Remediate PR #521 review blocker: `packages/mosaic/framework/tools/git/pr-merge.sh` must reject non-numeric PR numbers before metadata lookup/merge and must not use `eval` for GitHub merge execution.
+
+## Scope
+
+- Shell wrapper only: `packages/mosaic/framework/tools/git/pr-merge.sh`
+- Focused regression harness: `packages/mosaic/framework/tools/git/test-pr-merge-gitea-empty-uid.sh`
+- No API/frontend/infra surfaces.
+
+## Acceptance Criteria
+
+- AC1: `PR_NUMBER` is validated as digits-only immediately after required-argument parsing, before metadata lookup.
+- AC2: GitHub merge path uses a quoted argv array, not command-string construction plus `eval`.
+- AC3: Focused tests prove PR-number metacharacters are rejected and cannot execute injected shell commands on GitHub path.
+- AC4: Focused tests prove PR-number metacharacters are rejected on Gitea path before tea/curl merge calls.
+- AC5: Existing Gitea empty-uid fallback behavior remains green.
+- AC6: Syntax, shellcheck where available, focused harness, and relevant repo gates are rerun or absence documented.
+
+## Plan
+
+1. Add failing regression tests for GitHub eval injection and Gitea invalid PR rejection.
+2. Implement fail-closed PR number validation before metadata lookup.
+3. Replace GitHub `eval` command with argv array execution.
+4. Run required validation and update this scratchpad with evidence.
+5. Commit, queue-guard, push branch, update PR #521.
+
+## TDD Log
+
+- RED: `AGENT_WORK_ROOT="$HERMES_KANBAN_WORKSPACE/work" bash packages/mosaic/framework/tools/git/test-pr-merge-gitea-empty-uid.sh` failed on vulnerable code with `Expected GitHub metacharacter PR number to be rejected` and showed the injected PR number reached the GitHub merge path.
+- GREEN: Added digits-only validation before metadata lookup and replaced GitHub `eval` with an argv array. The focused harness now passes and verifies invalid PR numbers are rejected before GitHub `gh` calls and before Gitea `tea`/`curl` calls.
+
+## Validation Evidence
+
+- PASS: `AGENT_WORK_ROOT="$HERMES_KANBAN_WORKSPACE/work" bash -n packages/mosaic/framework/tools/git/pr-merge.sh packages/mosaic/framework/tools/git/test-pr-merge-gitea-empty-uid.sh`
+- PASS: `shellcheck -x packages/mosaic/framework/tools/git/pr-merge.sh packages/mosaic/framework/tools/git/test-pr-merge-gitea-empty-uid.sh`
+- PASS: `AGENT_WORK_ROOT="$HERMES_KANBAN_WORKSPACE/work" bash packages/mosaic/framework/tools/git/test-pr-merge-gitea-empty-uid.sh`
+- PASS: `pnpm --filter @mosaicstack/mosaic... build`
+- PASS: `pnpm --filter @mosaicstack/mosaic lint`
+- PASS: `pnpm --filter @mosaicstack/mosaic typecheck`
+- PASS: `pnpm --filter @mosaicstack/mosaic test` — 32 files / 291 tests passed.
+- REVIEW: `/home/hermes/.config/mosaic/tools/codex/codex-code-review.sh --uncommitted` could not run due Codex 401 Unauthorized. Independent delegate review completed read-only with PASS / no blockers; non-blocking suggestion to assert GitHub mock log remains empty was applied.
+
+## Risks / Blockers
+
+- No active blockers.
