Adam Moussa 8f28fbe6a5 Harden CI guard: symlink-escape reject, strict decode, scope canon; back with tests
Resolves the GPT-4.1 cross-review FIX items on the §3.3.2 CI apply/verify guard:
- Symlink-escape (Medium-High): reject any candidate diff that introduces a
  symlink (git mode 120000). A symlink can redirect a later in-diff write into a
  denied path that textual canonicalization cannot see; auto-built diffs have no
  legitimate symlinks, so this fails closed (exit 7).
- Diff-parse robustness (Medium): decode the diff as strict UTF-8 and fail closed
  (exit 8) instead of errors='replace', closing homoglyph/encoding evasion.
- Declared-scope canonicalization (Medium): drop parent-escaping scope globs so a
  malformed scope can only shrink coverage, never widen it past repo root.
- Egress allowlist (Low-Med): explicit DEPLOY marker to parameterize the
  build-test registries per target repo before enabling.

Backs the gate's correctness claim with a committed, runnable suite
(tests/test_ci_gate_workflow.py) that extracts the inline guard from the YAML and
exercises good + adversarial diffs (clean, hash mismatch, workflow delete,
copy-into-denied, symlink, non-UTF-8, out-of-scope, unscoped, escaping scope).
Corrects the README "Tests" section that claimed coverage that did not exist.
Full suite: 557 passed, 1 skipped; ruff clean.

agent-team — R720 Plane-2 FOUNDATION

Pre-deployment scaffolding for the R720 agent-team SDLC pipeline (design: ../docs/r720-agent-team-design.md). This commit ships the Plane-2 FOUNDATION layer only — the durable, transport-agnostic contracts the leaf builders import verbatim. Nothing here is provisioned, scheduled, or wired to live infrastructure.

Status: FOUNDATION modules only. No coordinator, no transports' concrete adapters, no CI workflow, no provisioning. Those are later phases (§7).

  tests/                      # pytest unit tests, one module per source module

The top directory is kebab-case (agent-team/); the importable package is snake_case (agent_team/), per the engineering handbook.

Modules (contracts)

Module Design ref What it provides
state_store §6.7 atomic_write(path, data) (write-temp → fsync → rename), read_checked(path, *, schema_version) (schema-version + content-hash integrity check, raises IntegrityError), compute_content_hash(data). Pure stdlib; no other agent_team deps.
db.schema §3.3.1, §6.7 SCHEMA_VERSION, PENDING_QUESTIONS_DDL, BUDGET_LEDGER_DDL, connect() (WAL + foreign_keys + busy_timeout), init_db(), migrate(), and the BEGIN IMMEDIATE compare-and-set helpers (answer_question/expire_question/supersede_question). SQL DDL lives only here.
billing §3.1 BillingMode{SUBSCRIPTION,API,BEDROCK}, claude_invoke(prompt, *, mode=None, **kw) -> ClaudeResult, resolve_mode(config). Single seam; subscription mode pops any stray ANTHROPIC_API_KEY so OAuth can't be overridden.
transport.base §3.3.1 Transport ABC (post_question → channel_ref; parse_answer → (question_id, answer, via)), QuestionSet, NormalizedAnswer. Transport-independent; Slack/GitHub/Claude-Code adapters subclass in the leaves.
task_model §3.3 TaskRecord, TaskStatus, Phase{INTAKE…DONE}, new_thread_id(), PipelineState TypedDict (LangGraph state schema), JSON serialization helpers. Pure model, no I/O.

Durable human-in-the-loop (§3.3.1)

The pending_questions ledger is the single durable source of truth for the question lifecycle. Every race (duplicate answers, transport redelivery, answer-vs-timeout) resolves via one atomic compare-and-set against the status column, run inside a BEGIN IMMEDIATE transaction so concurrent responders are serialized — first-answer-wins (rowcount == 1), late/duplicate ignored (rowcount == 0). The LangGraph SqliteSaver checkpointer creates its own tables against the same DB file.

Running the tests

cd agent-team
python3 -m pytest tests/ -q

tests/conftest.py puts the package on sys.path, so no install is required.

Not in this commit (later phases)

Coordinator/brain, concrete Slack/GitHub/Claude-Code transport adapters, the CI apply/verify workflow (§3.3.2), step-ca / Roles Anywhere, scheduling, and the operator CLI (run-team.py). See ../docs/r720-agent-team-design.md §7 for the phased rollout. Secrets are never committed.
