* fix(replay-e2e): match by conversation, not the living system prompt
The model-replay match key hashed the full input including the lead-agent
system prompt. That prompt is edited frequently (e.g. #3195 added a "File
Editing Workflow" section), so the committed fixture went stale the moment
the prompt changed on main — turning the Layer-2 render gate RED on every
unrelated PR (#3430, #3432, ...). This was a self-inflicted false positive.
Root-cause fix:
- replay_provider._canonical_messages now EXCLUDES the system message from
the hash. The conversation (human/ai/tool) is the stable contract that
identifies a recorded turn; the system prompt is an internal detail not
part of the front-back contract under test. (Mirrors how open-design keys
its mock picker on the user prompt, not the system internals.) Proven
robust: injecting a prompt edit no longer causes a replay miss.
- Layer-1 golden was BLIND to replay misses: the gateway swallows a miss
into an assistant error message, so the shape-only golden stayed green on
a stale fixture. It now inspects replay_provider.replay_misses() and fails
loud. (Layer-2 already fails on a miss.)
- Re-recorded write_read_file.ultra fixture + regenerated golden under the
new conversation-only hash.
- Layer-2 render spec: assert the in-graph auto-title (deterministic); the
follow-up suggestion is fired async and depends on a clean JSON model
output, so assert it only when the fixture captured one — never gate on
its absence (recording flakiness must not block CI).
- docs: REPLAY_E2E.md updated.
Verified: Layer-1 golden green (no miss), Layer-2 both specs green,
CI=true make test 4033 passed / 0 failed, frontend pnpm check clean.
* test(replay-e2e): restore suggestions coverage with a reliable capture
Addresses review feedback (the suggestion path was dropped from Layer-2):
- record spec now waits for the `/suggestions` response before checking
capture stability, so the recorded fixture reliably includes the
frontend-fired suggestions turn (previously the stability window could
return before suggestions fired, yielding a fixture without it).
- Re-recorded write_read_file.ultra: 5 turns (write_file, auto-title,
read_file, answer, suggestions). Golden unchanged — suggestions is a
separate /suggestions call, not part of the /runs/stream SSE sequence.
- Layer-2 spec: restore the hard `EXPECTED_SUGGESTION` assertion. With the
record spec now waiting for /suggestions, a fixture missing the suggestion
turn means a broken recording and must fail loud, not pass silently.
Verified: Layer-1 golden green (no miss), Layer-2 both specs green
(auto-title + suggestion render), frontend pnpm check clean.
* ci: re-trigger (flaky Docker Hub image pull in sandbox e2e, unrelated)
backend-unit-tests failed only in test_sandbox_orphan_reconciliation_e2e.py
with 'docker pull busybox:latest ... context deadline exceeded' — a CI-runner
network flake reaching Docker Hub, not related to this docs/tests-only change.
Empty commit to re-run CI.
