Mined per-spec failure data from the 32 completed Core E2E main runs
since the 2026-07-18 quarantine delist (failed-shard logs; a green
shard means every spec in it passed). 26 specs failed or retry-flaked
within the 10 most recent completed runs; they seed PROBATION_SPECS in
tests/integration/playwright.config.ts. The remaining 62 files form the
stable tier and are the only specs that can fail the e2e-verdict job.
Mechanism extends the existing quarantine list rather than adding a
parallel one: PULSE_E2E_TIER=stable ignores probation specs,
PULSE_E2E_TIER=probation runs only them, unset runs the full suite
(local behavior unchanged). CI runs both tiers per shard against the
same containers; the probation pass sits behind continue-on-error with
its own report/results dirs and artifacts, so a probation flake is
reported in the shard summary without painting main red.
Promotion rule, documented next to the list: a probation spec promotes
to stable after 10 consecutive green main runs with no failure and no
retry-flake; one incident on main demotes a stable spec back. In the
newest completed run (29729544151) every failure was in a probation
spec — under this split that run's verdict is green.
Contract-Neutral: CI-only E2E tier split: gating semantics of push-CI verdict; local npm test behavior and dev-runtime orchestration unchanged, no public contract delta
tests/integration/README.md and QUICK_START.md referenced the retired
.github/workflows/test-updates.yml; update-flow coverage now runs as
tests/79-update-flow.spec.ts inside the main suite via test-e2e.yml.
Backend:
- Add smart provider fallback when selected model's provider isn't configured
- Automatically switch to a model from a configured provider instead of failing
- Log warning when fallback occurs for visibility
Frontend (AISettings.tsx):
- Add helper functions to check if model's provider is configured
- Group model dropdown: configured providers first, unconfigured marked with ⚠️
- Add inline warning when selecting model from unconfigured provider
- Validate on save that model's provider is configured (or being added)
- Warn before clearing last configured provider (would disable AI)
- Warn before clearing provider that current model uses
- Add patrol interval validation (must be 0 or >= 10 minutes)
- Show red border + inline error for invalid patrol intervals 1-9
- Update patrol interval hint: '(0=off, 10+ to enable)'
These changes prevent confusing '500 Internal Server Error' and
'AI is not enabled or configured' errors when model/provider mismatch.
