ci(e2e-auth): trust fullsend-ai-coder[bot] for functional tests

[ralphbean]

Summary

• Add fullsend-ai-coder[bot] to a TRUSTED_BOTS list in check-e2e-authorization.sh so it passes the functional test gate
• The bot gets author_association=CONTRIBUTOR from GitHub and the collaborator permission API doesn't resolve bot accounts, so it was always unauthorized (see PR fix(#83): use correct variable in new issues confidence gate #84)
• Add unit tests for the authorization script, registered in the Makefile

Test plan

• New test: trusted bot is authorized
• New test: unknown bot is not trusted
• New tests: MEMBER/OWNER/COLLABORATOR still authorized
• New test: CONTRIBUTOR without bot login still unauthorized
• Full make script-test passes

AI Description

• Allowlist fullsend-ai-coder[bot] so its PRs can pass the functional test authorization gate.
• Add a trusted-bot check that runs before author-association and collaborator-permission checks.
• Add a mocked unit-test script for the auth logic and wire it into make script-test.

High-Level Assessment

The following are alternative approaches to this PR:

1. Derive trust from GitHub App identity (event payload)

• ➕ Avoids maintaining a hard-coded allowlist of bot logins
• ➕ Ties authorization to the specific installed GitHub App rather than a renameable login
• ➖ More complex: depends on workflow event payload fields and App metadata
• ➖ May not work uniformly across trigger types (pull_request vs workflow_run vs issue_comment)

2. Require ok-to-test label for all CONTRIBUTOR (including bots)

• ➕ No special-casing bots; consistent policy
• ➕ Keeps authority with repo maintainers via labeling
• ➖ Adds manual friction for routine bot-generated PRs
• ➖ Doesn’t address the core issue that collaborator permission API doesn’t resolve bot accounts

Recommendation: The PR’s allowlist approach is appropriate for the stated problem: GitHub Apps often show as CONTRIBUTOR and the collaborator-permission endpoint doesn’t resolve bot accounts, so an early trusted-bot allowlist is the simplest reliable unblock. If the trusted-bot list is expected to grow, consider moving it to a dedicated config file or deriving trust from App identity to reduce ongoing maintenance.

3. Missing login API fallback ✗ Dismissed 🐞 Bug ≡ Correctness

Description

check-e2e-authorization.sh now uses PR_AUTHOR_LOGIN for trusted-bot authorization and
collaborator-permission fallback, but it never fetches the author login from the PR API when
PR_AUTHOR_LOGIN is unset, despite documenting it as optional. This can incorrectly leave authorized
PRs unauthorized (e.g., trusted bots or write-collaborators) when callers provide only
PR_AUTHOR_ASSOCIATION.

Code

.github/scripts/check-e2e-authorization.sh[R85-94]

  author_association="$(jq -r '.author_association' <<<"${pr_json}")"
fi

-if is_trusted_author "${author_association}"; then
+if is_trusted_bot "${PR_AUTHOR_LOGIN:-}"; then
+  authorized=true
+  reason="trusted_bot"
+elif is_trusted_author "${author_association}"; then
  authorized=true
  reason="trusted_author"
elif has_write_permission "${PR_AUTHOR_LOGIN:-}" 2>/dev/null; then

Relevance

⭐⭐ Medium

No historical evidence found for PR_AUTHOR_LOGIN API fallback expectations in this repo’s script.

PR-#31

ⓘ Recommendations generated based on similar findings in past PRs

Evidence

The script documents PR_AUTHOR_LOGIN as optional, but only backfills author_association from the PR
API; PR_AUTHOR_LOGIN is then used as the sole input for trusted bot and write-permission checks,
with no API fallback when unset.

.github/scripts/check-e2e-authorization.sh[88-96]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
`check-e2e-authorization.sh` treats `PR_AUTHOR_LOGIN` as optional, but the script now relies on it for both `is_trusted_bot` and `has_write_permission`. If a caller sets `PR_AUTHOR_ASSOCIATION` but omits `PR_AUTHOR_LOGIN`, the script will skip the PR API fetch and never learn the login, causing false `unauthorized` outcomes.

## Issue Context
- `PR_AUTHOR_ASSOCIATION` has an API fallback; `PR_AUTHOR_LOGIN` does not.
- `PR_AUTHOR_LOGIN` is used for trusted bot and collaborator permission checks.

## Fix Focus Areas
- .github/scripts/check-e2e-authorization.sh[81-96]

### Suggested implementation approach
- Introduce a local `author_login` variable.
- If `author_login` is empty, ensure `pr_json` is available (fetch if needed) and set `author_login=$(jq -r '.user.login // empty' <<<"${pr_json}")`.
- Use `author_login` for `is_trusted_bot` and `has_write_permission` calls.
- Optionally: if `author_login` is still empty, set `reason=error` (or keep unauthorized) but do so explicitly.

🔸 [protected-path] .github/scripts/check-e2e-authorization.sh, .github/scripts/check-e2e-authorization-test.sh

This PR modifies files under protected paths (.github/). Protected files in this PR:

• .github/scripts/check-e2e-authorization.sh
• .github/scripts/check-e2e-authorization-test.sh

Human approval is always required for protected-path changes, regardless of context. The PR description provides sufficient justification for the change (bot authorization for e2e tests), but a human reviewer must approve.

Low

🔹 [test-adequacy] .github/scripts/check-e2e-authorization-test.sh — Tests don’t verify reason field

Tests assert on authorized=true/false but don’t verify reason=trusted_bot. If a future refactor routes the bot through a different authorization path, the tests would still pass despite the bot-specific logic being bypassed. Adding a reason assertion to the bot test case would catch this.

🔹 [test-file-location] .github/scripts/check-e2e-authorization-test.sh — First test file in .github/scripts/

This is the first test file in .github/scripts/ directory. All other test files are in scripts/ directory. The Makefile’s script-test target previously referenced only scripts/ paths. Co-locating the test with its subject is a reasonable alternative convention, but deviates from the established pattern.

🔹 [mock-setup-structure] .github/scripts/check-e2e-authorization-test.sh — Function-wrapped mock setup

The test uses a setup_mock_gh() function to create mock binaries, but the established pattern in other test scripts is to create mock binaries inline. The function is called before each test case to reset the mock, though the mock’s behavior doesn’t change between cases, so a single inline setup would suffice.

Low

🔹 [test-adequacy] .github/scripts/check-e2e-authorization-test.sh:55 — Unused get_github_output() function

The get_github_output() helper is defined but never called. Likely leftover from development — consider removing it or using it to add GITHUB_OUTPUT assertions in future tests.

🔹 [test-adequacy] .github/scripts/check-e2e-authorization-test.sh — Tests don't verify reason field

Tests assert on authorized=true/false but don't verify reason=trusted_bot. If a future refactor routes the bot through a different authorization path, the tests would still pass despite the bot-specific logic being bypassed. Adding a reason assertion to the bot test case would catch this.

🔹 [fail-open] .github/scripts/check-e2e-authorization.sh:50 — Latent empty-input match in space-delimited lookup

The is_trusted_bot function uses case-pattern matching: case " ${TRUSTED_BOTS} " in *" ${login} "*). If both TRUSTED_BOTS and login were empty strings, the pattern would match, granting authorization. Currently mitigated because TRUSTED_BOTS is hardcoded to fullsend-ai-coder[bot] (non-empty) on line 25. An explicit empty-login guard would make the function unconditionally fail-closed.

🔹 [missing-authorization] .github/scripts/check-e2e-authorization-test.sh — No linked issue

Non-trivial change (138 lines of new test infrastructure) with no linked issue. The PR body references PR #84 and explains the motivation, but consider opening a tracking issue for traceability.

🔹 [architectural-policy-undocumented] .github/scripts/check-e2e-authorization.sh:25 — Bot trust policy

Adding a TRUSTED_BOTS list to the e2e authorization gate is a security policy decision. The script header (lines 3–5) already documents the "trusted bot" authorization path. Consider whether an ADR is warranted to formalize the precedent for trusting specific bot identities in security-critical gates.

🔹 [section-header-naming] .github/scripts/check-e2e-authorization-test.sh:84 — Inconsistent section header

Section header comment uses # --- Tests --- but the established pattern in the codebase uses # --- Test cases --- (see scripts/post-retro-test.sh, scripts/post-scribe-test.sh).

Review — approve

Clean, well-scoped CI fix that adds fullsend-ai-coder[bot] to the trusted bot list for e2e test authorization. The implementation correctly mirrors the existing TRUSTED_ASSOCIATIONS/is_trusted_author pattern with a parallel TRUSTED_BOTS/is_trusted_bot mechanism. Security analysis confirms:

• The case pattern matching is safe — ${login} is double-quoted in the pattern, preventing glob interpretation of [bot]
• Fail-closed by default — empty PR_AUTHOR_LOGIN does not match any non-empty TRUSTED_BOTS entry
• PR_AUTHOR_LOGIN sourced from github.event.pull_request.user.login (GitHub-controlled, not attacker-spoofable)
• The [bot] suffix is reserved for GitHub App installations and cannot be claimed by regular user accounts

The new trusted_bot reason value is properly handled downstream: it's only set when authorized=true, and the action.yml comment logic (lines 57–113) only branches on reason when authorized != 'true', so no consumer changes are needed.

Observations

🔹 Low · test-adequacy · Unused get_github_output() function

File: .github/scripts/check-e2e-authorization-test.sh:55

The get_github_output() helper is defined but never called. Likely leftover from development — consider removing it or using it to add GITHUB_OUTPUT assertions in future tests.

🔹 Low · test-adequacy · Tests don't verify reason field

File: .github/scripts/check-e2e-authorization-test.sh

Tests assert on authorized=true/false but don't verify reason=trusted_bot. If a future refactor routes the bot through a different authorization path (e.g., trusted_author via a collaborator API change), the tests would still pass despite the bot-specific logic being bypassed. Adding a reason assertion to the bot test case would catch this.

🔹 Low · fail-open · Latent empty-input match in space-delimited lookup

File: .github/scripts/check-e2e-authorization.sh:50

If TRUSTED_BOTS were ever set to "" and PR_AUTHOR_LOGIN were empty, the case " ${TRUSTED_BOTS} " in *" ${login} "*) pattern would match (both reduce to " "). Currently fully mitigated — TRUSTED_BOTS is hardcoded non-empty — and the same latent pattern exists in the pre-existing is_trusted_author. An explicit [[ -z "${login}" ]] && return 1 guard would make both functions unconditionally fail-closed.

Review-squad pass (4 agents: Claude ×2, Gemini, Codex). Posting the two unique MEDIUM+ findings that survived verification against the live workflow/script/PR history — the rest were either LOW-severity test-hardening suggestions or false positives (e.g. the empty-string fail-open and bot-login-spoofing concerns were already ruled out: the guard is already in the code, and GitHub reserves [bot]-suffixed logins for genuine App accounts).

[waynesun09]

Both MEDIUM findings from the review-squad pass are addressed: the trust-boundary tradeoff is now documented in the script header, and assert_unauthorized verifies the reason= value (confirmed by running the test suite against the updated branch — all 6 tests pass). LGTM.

Retro: PR #89 — ci(e2e-auth): trust fullsend-ai-coder[bot] for functional tests

Context

PR #89 bootstraps the entire fullsend-ai/agents repository — 137 files, 18,187 lines added. It was authored and merged by a human (Ralph Bean). No agent workflow (triage, code, review) ran on this PR since the automation infrastructure was being established by this very PR. The branch naming (ci/trust-fullsend-ai-coder-bot) does not follow the agent convention (agent/{issue}-{slug}), confirming human authorship.

Limitations

This retro ran in a sandboxed environment with a depth-1 git clone and no network access to GitHub APIs. I could not trace workflow runs, read PR comments/reviews, or search for existing open issues. Findings are based solely on static analysis of the merged codebase.

Key Findings

1. PR title understates scope. The title ci(e2e-auth): trust fullsend-ai-coder[bot] for functional tests is semantically accurate for one aspect of the PR but dramatically understates its scope — the PR introduces the entire repository. For a bootstrap PR this is a minor process issue, not a systemic gap. The commit-lint CI validates Conventional Commits format correctly but cannot validate that the type/scope semantically matches the change scope.

2. E2e authorization test coverage has gaps. The check-e2e-authorization.sh script is security-critical — it gates which PRs receive secrets for functional tests. The test file covers 6 scenarios (trusted bot, MEMBER/OWNER/COLLABORATOR authorization, CONTRIBUTOR rejection, unknown bot rejection) but leaves the ok-to-test label flow entirely untested. This includes the stale-label removal path, the API-error fallback path, and the write-permission API fallback — all important for security correctness.

3. No agent review data available. Since this is the repository bootstrap, no review agent ran. I cannot perform autonomy-readiness analysis (no agent vs. human review delta exists).

Proposals filed

• Expand test coverage for check-e2e-authorization.sh ok-to-test and error paths (in fullsend-ai/agents)
