App agent-team-apply: app_id 4119505, installation 141992144 (not secrets — only
the .pem is). A 2026-06-24 test mint confirmed contents:write + actions:write +
repository_selection:selected. The box gets its own freshly-generated private key
(the CI-side AGENT_APPLY_APP_PRIVATE_KEY Actions secret is write-only and cannot
be re-exported); secure-copy it to the box and delete the Mac copy after.
The P3 dispatcher's default seams shell out to gh/git, but the R720 box has
no gh and a read-only PAT with no Actions scope — so dispatch_apply_verify
returned no run_id and every task parked at verify ("dispatch unresolved").
Add a GitHub-App auth path: the box mints short-lived (~1h) installation
access tokens from the App private key and uses them for the three dispatch
seams, removing the gh dependency.
- agent_team/github_app.py (new): mint_installation_token (RS256 App JWT,
iss=app_id, iat backdated 60s, exp 9 min; POST /access_tokens) + a lazy
TokenProvider that caches and re-mints near expiry. Secret-safe: the JWT
and token are never logged, never in an exception message, never persisted.
- dispatcher.py: app_branch_pusher / app_workflow_dispatcher / app_run_locator
(additive; gh/git _default_* left untouched). Push auth rides a host-scoped
http.extraHeader via GIT_CONFIG_* env (token never in argv/ps); the REST
run locator maps id->databaseId / created_at->createdAt into select_run_id
and surfaces 4xx promptly instead of silently exhausting the poll window.
- coordinator.py: default_dispatch_node_factory binds the App seams when
AGENT_TEAM_GH_APP_ID / _INSTALLATION_ID / _PRIVATE_KEY are all set; partial
or unreadable config logs one warning and falls back to gh-default (never
raises at serve-start).
- requirements.txt: pin PyJWT, cryptography, requests (App seams + CI fetcher).
- DEPLOY-R720.md / README.md: App dispatch config, permission/scope audit,
env-precedence check, key rotation/revocation + incident response.
Tests: +18 (test_github_app.py new; dispatcher/coordinator additions) covering
JWT claims, cache/re-mint, token-scrub-on-error, REST field mapping + run-name
correlation, and the partial-env inert fallback. Full suite 1523 passing.
README: two human gates (clarifier + plan-decision), the approve/request-changes/
abandon verbs, free-text-defaults-to-request-changes, MAX_PLAN_GATE_VISITS, and
the planner max_turns reliability fix.
OPERATOR-RUNBOOK: how the gate appears in Slack, the three decision paths
(buttons/modal/free-text), the single-open-gate invariant, ceiling→PARKED, and
the 24h expiry→PARKED→recovery (re-assign / force-resume).
DEPLOY-R720: the pending_questions.kind ledger migration (SCHEMA_VERSION→4,
idempotent additive ALTER on startup) + rollback (restore the ledger backup
before restart if the migration fails).
P1c deploy artifacts: DEPLOY-R720.md (snapshot-first, rsync, venv deps, ~/secrev.env tokens incl. AGENT_TEAM_SLACK_OWNER_IDS, init-db, systemd, the 4-criteria live demo, rollback) and the long-running coordinator service unit.
