Closes #1415.

Scope

Port the operator-tree grant-reviewer tool into the framework as packages/mosaic/framework/tools/git/grant-reviewer.sh, with a hermetic regression suite test-grant-reviewer.sh and its enumeration line in test:framework-shell. No other wrapper is touched. tools/** is framework-owned in framework-manifest.txt (only tools/_lib/credentials.json is carved out), so no manifest change.

grant-reviewer.sh -u <user> [-r <owner>/<repo>] [-t <team>] — -r defaults to the current repo's origin (owner must be an org), -t defaults fleet-reviewers.
Gitea only: PLATFORM=github exits with a clear "Gitea only" error before any API call.
Idempotent: exact-name team lookup before create (the search endpoint substring-matches, so exact-name filtering is done on the response); create payload is permission: read + units_map {repo.code: read, repo.issues: write, repo.pulls: write}; member add and repo add are idempotent PUTs.
Fail-closed read-back (issue-comment.sh pattern, #865 defect class): after the PUTs, GET /teams/{id}/members/{user} and GET /teams/{id}/repos/{owner}/{repo} must both confirm the grant or the run fails. A 204 is an exit code, not evidence of a durable write.
HTTP 403 on any step surfaces as org admin required on '<org>' and stops the run — never a silent partial grant.
Identity: GITEA_LOGIN names a tea login whose host-matched token MUST resolve (fail closed, no downgrade to the host default identity); otherwise the detect-platform.sh identity ladder applies. Token travels via a curl --config file, never argv. Firewall respected: no hosts, seat names, or fleet paths in the deliverable.

Supplement decision (official=false under branch protection)

Field finding from first real use (usc/infrastructure PR 273): Gitea computes a review's official flag at submission time from write permission or the protected branch's approvals whitelist, so approvals from this read-permission team do not count toward required_approvals and a protected trunk still refuses merge.

Of the two options offered, this PR takes documentation, not a --whitelist-approvals flag: the limitation is documented prominently in the script header, the usage text, and the success output (including that a review submitted before whitelisting must be re-submitted). Rationale: who counts as an official approver is review policy — an operator decision — and Gitea's branch-protection edit API is a partial-update surface where an automated PATCH risks resetting unrelated protection settings. The flag can be added later behind an explicit opt-in if the operators want it.

Verification

bash framework/tools/git/test-grant-reviewer.sh → grant-reviewer.sh org-team grant + fail-closed read-back regression passed, rc=0. The suite is hermetic (sandboxed HOME/XDG, empty repo-local mosaic.gitIdentity pin, curl/tea stubs, persistent on-disk server state); cases cover fresh grant with exact-payload validation, idempotent re-run against a substring-named decoy team listed first, GitHub refusal, non-org owner, 403 mapping with no partial grant, both PUT-without-persist sabotage modes, GITEA_LOGIN per-request identity binding, unresolvable GITEA_LOGIN fail-closed with zero API calls, token-not-in-argv, and temp-file-leak checks.
Sabotage controls (defect re-introduced, suite must go red, then restored green):
- substring team match → red at the fresh case: Found existing team 'fleet-reviewers' (id 99) followed by an unexpected request against the decoy team.
- read-back removed (trust PUT exit codes) → red: FAIL: member-put-noop was reported as success.
- restore → suite green again.
bash framework/tools/quality/scripts/check-test-enumeration.sh → OK (population 71, enumerated 57, excluded 15).
pnpm preflight rc=0, pnpm typecheck rc=0, pnpm lint rc=0, pnpm format:check rc=0.

feat(tools/git): add grant-reviewer.sh org-team reviewer grant with fail-closed read-back (#1415 )

ci/woodpecker/pr/ci Pipeline failed

Details

deb4760b11

Port the operator-tree grant-reviewer tool into the framework suite.
grant-reviewer.sh -u <user> [-r <owner>/<repo>] [-t <team>] grants a
reviewer code-read plus issues/pulls-write on an org-owned Gitea
repository via an org team (default fleet-reviewers). Gitea only; on a
GitHub remote it refuses with a clear error.

Idempotent: exact-name team lookup before create (permission read,
units_map: code read, issues write, pulls write); member and repo
additions are idempotent puts. Fail-closed read-back: after the writes,
the single member resource and the single team-repo resource are both
fetched back and must confirm the grant or the run fails — a success
status is an exit code, not evidence of a durable write (#865 defect
class). HTTP 403 on any step surfaces as 'org admin required on <org>',
never a silent partial grant.

Identity follows issue-comment.sh: GITEA_LOGIN names a tea login whose
host-matched token MUST resolve (fail closed, no downgrade to the host
default); otherwise the detect-platform.sh identity ladder applies. The
bearer token travels via a curl config file, never argv.

Documented limitation (field finding, usc/infrastructure PR 273): under
branch protection with required approvals, reviews from a
read-permission team are official=false and do not count toward the
required total; whitelisting the team on the protected branch is an
operator review-policy decision this script deliberately does not
automate, and official is computed at review submission.

Hermetic suite test-grant-reviewer.sh models a real server with
persistent on-disk state, exact-payload validation, a substring-named
decoy team, write-without-persist sabotage modes, identity-per-request
assertions, and token-not-in-argv plus temp-leak checks; enumerated in
test:framework-shell.

FAIL (REQUEST_CHANGES) at deb4760b11 — single blocking finding, tool content itself is sound. B1: grant-reviewer.sh ships UNDOCUMENTED — check-tools-index.sh (a sanitization-step gate) fails: git category 96% (29/30), grant-reviewer.sh undocumented. Pipeline 2659 at this head is terminal-FAILURE at sanitization for exactly this reason (enumeration guard passes 71/57/15; verify-sanitized passes; I ran each component at the head to isolate it). Fix: add the tool to the shipped index docs (framework/defaults/TOOLS.md, plus TOOLS-REFERENCE.md if a CLI reference entry is warranted) in the same commit, then re-run the pipeline — same defect class as PR 1409's, different instrument. Everything else verified PASS: firewall clean (verify-sanitized green, zero seat/host/operator references); documentation-over-auto-PATCH design endorsed (operator-owned policy; the official=false + resubmission subtlety is documented in header, usage, AND success output); suite is an honest stateful-server model, run twice green, and my own sabotage (member read-back deleted) fails it — probe corrections disclosed in the record; credential hygiene sound (auth via curl --config file, argv captured clean every case, per-case temp-leak asserts including the token-bearing auth file).

docs(tools): index grant-reviewer.sh in TOOLS.md and TOOLS-REFERENCE.md (#1415 )

ci/woodpecker/pr/ci Pipeline was successful

Details

b023b1a4dc

Review finding B1 on PR #1417: the tool shipped without an index entry, so
check-tools-index.sh failed (git suite 29/30) and pipeline 2659 went
terminal-red at sanitization. Adds the suite row note in defaults/TOOLS.md
and an Access grants table in guides/TOOLS-REFERENCE.md, both naming the
official-approval limitation. check-tools-index.sh now rc=0 (git 30/30);
format:check and the enumeration guard stay green.

PASS at b023b1a4dc (delta re-review; supersedes my REQUEST_CHANGES 297 at deb4760b). B1 closed: index entries verified in both shipped docs (TOOLS.md reviewer-grants entry + TOOLS-REFERENCE Access-grants row, both naming the official-approval limitation); check-tools-index at the head: rc 0, git 30/30 enforced (spot-checked myself, as were enumeration 71/57/15 and workspace format:check rc 0). Delta is docs/index only - zero bytes into the tool or suite; all round-1 lanes carry (firewall, design endorsement, suite honesty incl. my read-back sabotage, credential hygiene), suite re-confirmed at head. Pipeline 2661 RUNNING at review time with SANITIZATION already OK - the step that failed 2659; no REGISTRY_* red at pull time.
