feat(activities): resolve_context stub + evaluate_templates — T15/T16
...
activities.py — resolve_context (T15):
- dispatches on source.type: 'static' returns config["value"]
- 'http_get' / 'db_query' raise ApplicationError(non_retryable=True)
- unknown types raise ApplicationError(non_retryable=True)
template_engine.py — evaluate_templates (T16, pure function):
- evaluates optional condition expressions against context snapshot
(restricted eval, no builtins)
- interpolates {context.<name>.<key>} placeholders via str.format_map
- returns list[{task_type, params}] with falsy-condition rows omitted

feat(activities): implement load_activity_definition — T14
...
activities.py:
- init_session_factory(url): module-level async_sessionmaker init,
called once from worker.py before workers start
- load_activity_definition(activity_id): queries activity_definitions
by UUID, returns JSON-serialisable dict; raises ApplicationError
(non_retryable=True) if row not found
worker.py:
- reads ACTCORE_DB_URL at startup, fails fast if missing
- calls init_session_factory() before connecting to Temporal

feat(worker): scaffold activities, workflows, worker entrypoint — T13
...
src/activity_core/activities.py:
- load_activity_definition, resolve_context, log_run — @activity.defn
stubs (raise NotImplementedError, bodies in T14–T17)
src/activity_core/workflows.py:
- RunActivityWorkflow (orchestrator-tq) — @workflow.defn stub (T18)
- TaskExecutorWorkflow (task-execution-tq) — @workflow.defn stub (T19)
src/activity_core/worker.py:
- Connects to Temporal via TEMPORAL_HOST / TEMPORAL_NAMESPACE env vars
- Spawns two Workers: orchestrator-tq and task-execution-tq
- Runs until cancelled (python -m activity_core.worker)

feat(db): add dev seed script for ActivityDefinition — T12
...
src/activity_core/seed.py: inserts one example ActivityDefinition
('example-heartbeat', cron every minute, static context source,
log_message task template). Idempotent — skips by name on re-run.
Run with:
ACTCORE_DB_URL=postgresql+asyncpg://actcore:actcore@localhost:5433/actcore \
python -m activity_core.seed

feat(db): ORM models + Alembic migrations 0001–0003 — T09/T10/T11
...
SQLAlchemy ORM (src/activity_core/orm.py):
- ActivityDefinition, ActivityRun, TaskInstance mapped to Base.metadata
- Wired into migrations/env.py for autogenerate support
Migrations (chained 0001 → 0002 → 0003):
- 0001: activity_definitions (id, name, enabled, trigger_type,
trigger_config JSONB, context_sources JSONB, task_templates JSONB,
dedupe_key_strategy, version, created_at, updated_at)
- 0002: activity_runs (run_id, activity_id FK→activity_definitions,
scheduled_for, fired_at, context_snapshot JSONB, tasks_spawned,
version_used) + index on activity_id
- 0003: task_instances (id, run_id FK→activity_runs CASCADE,
type, params JSONB, status, created_at) + index on run_id

feat(db): init Alembic (async) + SQLAlchemy declarative base — T08
...
- alembic init -t async migrations
- alembic.ini: dev fallback URL postgresql+asyncpg://…:5433/actcore;
ACTCORE_DB_URL env var overrides at runtime; src/ added to sys.path
- migrations/env.py: reads ACTCORE_DB_URL, wires target_metadata to Base.metadata
- src/activity_core/db.py: DeclarativeBase subclass + make_engine() helper
Tool choice: Alembic + SQLAlchemy[asyncio] (already declared in pyproject.toml).
Migrations run with: ACTCORE_DB_URL=... alembic upgrade head

Add project scaffold: contracts, schemas, docker-compose, workplans
...
Phase 0 contracts (event envelope, ActivityDefinition, idempotency doc,
naming conventions) and Phase 1 Temporal cluster setup (docker-compose.dev.yml,
Temporal dynamic config) are complete. Includes Pydantic models, JSON schemas,
wiki architecture docs, and ADR-001 workplan files for both workstreams.
