- ProviderEventLoop.stop(): close_all_sessions fan-out on the live loop before detach +
bounded pending-task drain before loop.close() (zero 'Task was destroyed' live-proven);
close_all_sessions weak-registry shutdown fan-out in browser_session_managers.
- SCEX-FR-038 independent mutation readback: browser_readback.py (same-session fresh
client_id SELECT, cleanup-aware expectation, canonical 6dp float normalization);
transport wiring adds readback_verified checkpoint; BrowserTransportReadbackMismatch ->
reconciliation_required/effect unknown/retry blocked; INV_7 kept (browser.py 395 LOC
via factory-helpers extraction).
- Live canaries: actions/mutation (readonly-canary-20260918T174659/174740/184343Z) and
native filters (filters-canary-20260918T195946Z: values/clear/replay/chart PASS; date
vector absent on stand — external prerequisite).
- Robustness fixes from live flake: pre-apply Escape (stale overlay in reused sessions)
and bounded antd dropdown settle in browser_native_filter.
- Root-cause of the 82.75/82.74 divergence: mid-step post-SELECT vs post-restore
lifecycle skew, not a cache defect.
The 044 provider lifecycle is decomposed to satisfy INV_7 and closed with live canaries;
the remaining acceptance row (T046 graph-level terminal PASS) is diagnosed with executable proof.
- split browser_readonly_actions (534->160), browser_session (501->58) and browser.py (407->398)
into sibling modules with frozen contract IDs and frozen import surface (facades re-export every
moved public name); monkeypatch seams follow the owning modules
- gates per phase: scoped 044 suite 1590 passed and full backend 11269 passed / 0 failed, no delta
- T042b: six PREPROD browser canaries GREEN under the Wave-C run-scoped session architecture;
harness gains SS_CANARY_STORAGE_ROOT and fixes the dead-loop scheduler drain hang
- T044: new artifact-content live HTTP canary 11/11 (real app, PostgreSQL, JWTs, live-captured bytes)
- T045: new fault-injection canary 16/16 (bounded loop refusals, deadline cancellation, shutdown
drain, capacity quarantine + TTL reconcile, receipt CAS, late response, cancel drain)
- T046: walker-level evaluation->comparison binding diagnosed (compare-only + mandatory ->
EVALUATION_UNAVAILABLE; bound evaluation -> BASELINE_AND_SEMANTIC_PASS); T043/T046 stay open
- refresh 044 spec/traceability/checklist/quickstart/SESSION_STATE/contracts/plan/data-model and the
037/050 rows to evidence-backed states; split three malformed multi-target @RELATION lines
- fix skill drift in semantics-python/semantics-svelte (logger facade, notify(), i18n proxy)
Add 2026-09-08 production gap/spec-coverage/refresh-plan and dashboard
scenario E2E plan/report, axiom-mcp feedback, and 2026-09-11 data-team
maintenance dev-test run notes.
Structure-first validation: prose double-hyphen passes, SQL in title rejected,
needs_baseline is not a promotion gate, legacy snapshot stays free-text scan.
Module load of maintenance.svelte.js happened inside the first test via
dynamic import and exceeded the 5000ms testTimeout under full-suite
parallel load. Move to a single hoisted static import (mock factories
now resolve vi.fn()s created via vi.hoisted) and drop a dead no-op
placeholder test. 39/39 in isolation, 3563/3563 full suite.
- sidebarNavigation.ts: static SIDEBAR_SECTIONS registry (i18n labelKey) + getTogglableFeatureNodes() with per-flag dedup
- projectSections.json: shared feature-id manifest; vitest guard pins nav ids to it, pytest guard pins it to FeaturesConfig fields
- FeaturesSettings: toggles derived and grouped by sidebar section/category, extra block for non-nav flags
- features.svelte.ts: reactive flags store; sidebar rebuilds live after settings save, untracked health polling
