Phase 2 configures forge for the agents (operator only sets a credential_ref +
optional version pin) and lets them drive a junior→senior→deploy workflow:
- Credential resolution/injection (control/credentials.py): credential_ref pointers
(env:/file:/cmd:) resolved only at spawn, injected as FORGE_TOKEN + host var, with a
forge-host-scoped git credential helper reading the token from env (never on disk / in
the DB). Resolution is a fail-fast spawn gate.
- Role-based forge skills committed into the managed repo (control/skills_gen.py,
`handler forge-init`): forge-junior/senior/deploy + a workflow overview.
- Hard approval gate (hooks/gate.py, approvals table, migration 0002): merge/deploy —
and direct pushes to protected branches — are denied unless a DIFFERENT agent has an
`approved` record for the branch, pinned to the reviewed commit (approved_sha). Senior
records verdicts via `handler approve`/`reject`.
- forge/git seams (control/forge.py, control/gitops.py) matching the Phase 1 seam pattern.
- CI status poller (control/poller.py, `handler poll-ci [--watch]`) backfilling
ci_status/ci_checked_at via `forge ci list`.
- Fix: migrations/env.py commits explicitly after run_migrations — pysqlite on Py 3.12+
was rolling back the final migration's DDL + alembic_version stamp (latent in Phase 1).
Reviewed via a separate code-reviewer pass; gate-bypass and credential-scoping findings
addressed. 106 tests, ruff clean, verified end-to-end against real git + migrations.
