Phase 1 of TODO-agent-2: pure logic plus the tables it writes to.
- domain/workforce/pipeline.py: Stage/PipelineKey/Outcome, the four pipelines,
TRANSITIONS, next_stage, STAGE_ROLE (role+mode), resolve_pipeline with the
no-reviewer fallback, task-kind defaults, stage -> coarse tasks.status, and
the TaskPipelineState record (with the optimistic version).
- application/engine/protocol.py: the [[TAG attr="v"]]body[[/TAG]] parser and
its self-closing form, the per-role/mode allow-list, literal bodies (a
bracket inside a body is not a tag), typed readers (ASSIGN/CREATE_TASK/
team changes/KNOWLEDGE/EDIT_FILE blocks) and the per-reply limits
(3 tasks, 3 team changes, 3 knowledge items).
- application/engine/state.py: advance() with the optimistic compare-and-set
and park_dependents() so a failed dependency never deadlocks its children.
- db/models_engine.py + migration a2b3c4d5e6f2: task_pipeline_state,
employee_profiles, engine_turns, gate_results as side tables (tasks and
employees stay locked). Linear head; alembic check reports no drift.
- repositories/engine.py + 58 new tests (test_engine_protocol,
test_engine_pipeline) covering every pipeline's happy path, illegal
transitions, exactly-one-winner concurrent advance, dependency parking and
all parser edge cases.
Suite: 594 passed, ruff clean, mypy clean.
