Per .claude/rules/output-coverage.md every node ships test/_output-manifest.md
enumerating every output across every state. This manifest covers all the
outputs added by slices #34-#42 in this PRD:
- Port 0 upsert message: every key (topic, url, method, headers, payload,
meta) with type and tested states.
- Port 1: explicit "not used" with rationale.
- Port 2: explicit "not used" with rationale.
- Structured log outputs: 5 events (regen-emitted, regen-skipped,
manual-regen-requested, parent-panels-deduped, flows:started) with
fields and corresponding test.
- specificClass return shapes: 6 methods with populated + degraded states.
- Anti-patterns enforced: no payload:null, absent vs null discipline,
tab id avoidance in predicate.
- test/_output-manifest.md: the manifest.
- test/basic/slice43-output-manifest.basic.test.js: 6 cross-cutting tests
exercising populated AND degraded states (token absent, folderUid absent,
template missing, diff-skip, regen logging, manual regen).
Backfill manifests for other nodes tracked in IMPROVEMENTS_BACKLOG.
