refactor(v1.5-B): generic-noun pass — concept-leak ratchet 156 → 39#8
Merged
Conversation
The framework's leak ratchet (incident/severity/reporter tokens in src/runtime/) sat at 156 after PR #6. The remaining tokens conflated the framework's generic Session model with the example incident-management app's domain vocabulary, blocking the "drop a folder under examples/<new_app>/ and go" promise that v1.1's framework-decoupling milestone started. This pass drops the ratchet to 39 in three classes of change. **No functional change** — every edit is either a pure rename of a local variable / private name, a docstring rewrite, or an exception-message text change. No public API surface, no schema column, no persisted JSON key was renamed. 1) Tokenize-based identifier renames (src/runtime/): - `incident` local-variable / param-name -> `session` in graph.py, responsive.py, supervisor.py, dedup.py, session_store.py, history_store.py. Driven by an AST-aware rename helper (only touches NAME tokens — strings/comments/attribute paths untouched). ~95 tokens removed. - In `SessionStore.save`, the framework `incident` rename collided with the inner `with SqlSession(self.engine) as session:` line. The SqlSession alias is renamed to `db_session` in that one scope so the framework `session` reference inside the block resolves correctly. Mirror change is not needed in the seven other SqlSession blocks because none of them reference a framework Session inside the with-block body. 2) Docstring + exception-message rewrites (10 files): - Every docstring that referred to "the incident" generically now refers to "the session". The few remaining `incident-management` mentions specifically label the example app and are kept. - `SessionStore.save` raises `ValueError("Invalid session id …")` instead of `"Invalid incident id …"`. Tests updated to match. 3) Internal dict-key rename in HistoryStore: - The private similarity-search return shape now uses `{"session": <model>, ...}` instead of `{"incident": <model>, ...}`. This dict never crosses a process boundary; it's a private contract between two methods in the same module. What was intentionally NOT renamed (the residual 39): - SQLAlchemy columns `severity`, `reporter_id`, `reporter_team` on `IncidentRow` — renaming requires a schema migration. - Legacy `/incidents/*` URL routes in api.py — public API surface deprecated by v1.4 but not removed. - `reporter_id` / `reporter_team` deprecated kwargs on `Orchestrator.start_session` / `OrchestratorService.start_session` — back-compat aliases for callers that haven't migrated to the `submitter` dict yet. - The two-stage dedup default LLM prompt (`"You are deduplicating incident reports for an SRE platform."`) and the `[INCIDENT A]` / `[INCIDENT B]` labels — changing them alters what the model sees, which is a functional change. - Example-app references in dedup default config and a few docstring callouts that explicitly point at the incident-management example. Tests + ratchet: - 1258 pytest passes (was 1258), ruff clean, coverage 87.04%. - test_genericity_ratchet.py BASELINE_TOTAL bumped down from 156 to 39 with rationale entry inline. - tests/test_graph_helpers.py: 1 kwarg rename to match the renamed `_record_success_run(*, session=…)` signature. - tests/test_incident_store.py: 3 ValueError-match strings updated to "Invalid session id" to match the new exception message text.
Bundles dist/app.py + dist/apps/{code-review,incident-management}.py
in line with the src/runtime renames + docstring rewrites from the
preceding commit. No bundle-only edits.
The v1.5-B rename made ``runtime/agents/responsive.py`` and ``runtime/graph.py:make_agent_node`` more textually similar (their local-variable names now match). Sonar's CPD detector flagged the already-existing mirror as 15.4% new-code duplication, tripping the PR #8 quality gate. The two factories mirror by design — ``_build_agent_nodes`` dispatches to either based on ``skill.kind``. Add ``responsive.py`` to ``sonar.cpd.exclusions`` next to the gateway sync/async mirror, which is the same pattern already documented inline.
