E2E pipeline test exercises the full Lane A → B → C value loop:
1. Set up fake $HOME with all 8 memory source types as fixtures
2. gstack-memory-ingest --probe verifies counts match disk
3. gstack-memory-ingest --incremental writes state with schema_version: 1
4. Idempotency: re-run reports 0 changes
5. --probe distinguishes new vs unchanged after first incremental
6. gstack-gbrain-sync --dry-run previews 3 stages
7. --no-code --no-brain-sync --quiet writes sync state with 1 stage entry
8. office-hours/SKILL.md V1 manifest dispatches 4 queries (mode=manifest)
9. Datamark envelope wraps every loaded section (Section 1D + D12)
10. Layer 1 fallback when no skill specified — default 3-section manifest
11. plan-ceo-review/SKILL.md manifest also dispatches (regression for V1
manifest authoring across all 6 V1 skills)
Side effect: bin/gstack-memory-ingest.ts gains --no-write flag (also
honored via GSTACK_MEMORY_INGEST_NO_WRITE=1 env var). Skips gbrain put_page
calls while still updating the state file. Used by tests + dry-runs to
avoid real ingest churn when verifying state-file lifecycle. The
--bulk and --incremental modes still call gbrain by default — only
explicit opt-in suppresses writes.
