Archive Report — prometheus-direct-charting

Phase: archive · Change: prometheus-direct-charting · Repo: /home/user/manage Mode: file-backed (artifactStore: openspec). No source-code edits; only OpenSpec artifacts were touched. Not committed — the parent/orchestrator owns the archive commit. No push, no gh.

Status: ARCHIVED. All eight lifecycle phases are complete (proposal → spec → design → tasks → apply → verify → sync → archive). Every archive precondition is verified PASS (see §2). The canonical openspec/specs/prometheus-charting/spec.md (created by sdd-sync) remains in place as the durable end-state spec and is not moved (archive never moves canonical specs). The change folder was moved to openspec/changes/archive/2026-07-08-prometheus-direct-charting/ via git mv to preserve history.

0. Archive disposition

• Disposition: archived. The folder move was performed inline as instructed (unlike a documented-pending-manual outcome): the parent explicitly requested the git mv and owns the commit, so the move is executed here and left staged for the parent's explicit-path commit.
• Archive convention: OpenSpec SDD archive contract for openspec mode — completed file-backed sync → write the in-folder archive report → move the change folder to openspec/changes/archive/YYYY-MM-DD-{change}/. No standalone manifest/index exists under openspec/ (only config.yaml, changes/, specs/), so the folder move is the archive mechanism. No rules.archive override exists in openspec/config.yaml.
• Target archived path: openspec/changes/archive/2026-07-08-prometheus-direct-charting/
• Archive date: 2026-07-08 (ISO).
• Canonical spec left in place (not moved): openspec/specs/prometheus-charting/spec.md — 27 requirements (SC-101 … SC-127). Verified present and untouched after the move.
• openspec/specs/web-ui/spec.md also left untouched (the other canonical domain).
• Audit-trail integrity: the change folder was moved as a whole, including the legacy flat spec.md and the per-domain delta specs/prometheus-charting/spec.md, which travel with the record. Nothing was silently deleted or rewritten. The flat spec.md is retained as the authoritative planning artifact the work was built against.

1. Native sdd-status read & discrepancy statement

The native gentle-pi.sdd-status engine supplied by the parent reports non-actionable state for this archive because it was resolved without a change context: changeName: null, artifacts: all missing, applyState: blocked, dependencies.archive: blocked, blockedReasons: ["Change selection is ambiguous: mobile-responsive-parity, prometheus-direct-charting, service-storage-harness, services-as-hub-ia."], isNonAuthoritative: false. This is a parent-resolution artifact: the engine auto-detected four active changes and could not pick one. The ambiguity does not reflect the state of prometheus-direct-charting, which this archive task was explicitly assigned.

Discrepancy with the parent's authoritative confirmed state — RESOLVED in favor of the parent. The parent physically verified (and this executor re-confirmed directly against the filesystem in §2) that all 39 tasks are ticked, apply-progress.md exists and records the work, and the verify report confirms functional completion with no blocking findings. Per the archive contract's non-authoritative-store carve-out guidance and the parent's explicit instruction, the stale archive: blocked / "ambiguous" labels are disregarded and the archive proceeds.

Direct filesystem re-validation (§2) is the source of truth for this report.

2. Archive preconditions (validated directly against the filesystem)

Precondition	Evidence	Result
Verify report present	verify-report.md	✓ verdict PASS
Verify clearly passing — no unresolved FAIL/BLOCKED/CRITICAL	verify-report §9: the sole CRITICAL was an archive-only checkbox/apply-progress gap (now reconciled); SC-125 PARTIAL→PASS closed	✓
Sync report present & successful	sync-report.md → Status: SYNCED	✓
Canonical spec exists (sync target)	openspec/specs/prometheus-charting/spec.md (27 requirements)	✓
Change-side domain delta exists	specs/prometheus-charting/spec.md	✓
Delta op-class = pure ## ADDED (non-destructive)	ADDED=1, MODIFIED=0, REMOVED=0, RENAMED=0 (new domain)	✓
Requirement-ID parity (flat ↔ delta ↔ canonical)	27 == 27 == 27, identical IDs SC-101…SC-127	✓
proposal / design / tasks artifacts present	all populated	✓
Final Task Completion Gate — zero unchecked - [ ]	grep -nE '^\s*- \[ \]' tasks.md → NONE; grep -cE '^\s*- \[x\]' → 39	✓
apply-progress.md present & records the work	present; status "complete — all 39 tasks done", 3 slices + coverage close documented	✓
No active same-domain (prometheus-charting) collision	only this change carries a prometheus-charting delta	✓

Stale-checkbox reconciliation note. At verify time, 19 implementation/verification checkboxes (Slice 3 §3.1–3.14 and Integration §4.1–4.5) were unchecked and apply-progress.md did not exist. That condition was reconciled before archive: the boxes are now all ticked and apply-progress.md was authored documenting the three landed slices and the SC-125 coverage close. apply-progress.md plus the verify report prove every previously-unchecked task complete. No archive-time mechanical checkbox repair was needed — the gate now passes on the persisted tasks.md as-is. No partial-archive approval applies.

3. Artifacts read (archive preflight)

• openspec/changes/prometheus-direct-charting/proposal.md
• openspec/changes/prometheus-direct-charting/spec.md (flat, authoritative planning artifact — 27 requirements)
• openspec/changes/prometheus-direct-charting/specs/prometheus-charting/spec.md (change-side domain delta)
• openspec/changes/prometheus-direct-charting/design.md
• openspec/changes/prometheus-direct-charting/tasks.md
• openspec/changes/prometheus-direct-charting/apply-progress.md
• openspec/changes/prometheus-direct-charting/verify-report.md
• openspec/changes/prometheus-direct-charting/sync-report.md
• openspec/specs/prometheus-charting/spec.md (canonical, sync target — verified present and untouched)
• openspec/config.yaml (rules: proposal/tasks; no rules.archive override)

The legacy flat spec.md is not the only spec artifact: a per-domain delta (specs/prometheus-charting/spec.md) and a canonical spec both exist, so the "legacy flat spec as the only artifact" archive-block condition does not apply. The flat spec travels with the archived folder as part of the audit trail.

4. Domains synced & requirement delta

Domain	Change-side delta	Canonical	Action
prometheus-charting	specs/prometheus-charting/spec.md	openspec/specs/prometheus-charting/spec.md	NEW domain — pure ADDED (27 requirements)

• ADDED (27) — all to the new prometheus-charting domain (canonical did not exist pre-change). IDs and text preserved verbatim from the verified flat spec.md. Grouped logically:
  • Direct Prometheus range query path — SC-101, SC-102, SC-103, SC-104
  • Prometheus chart widget (rebrand + rebind) — SC-105, SC-106, SC-107, SC-108
  • Prometheus gauge widget — SC-109, SC-110, SC-111
  • Prometheus mean widget — SC-112, SC-113, SC-114
  • Grafana removal — SC-115, SC-116, SC-117, SC-118, SC-119, SC-120
  • Configuration documentation accuracy — SC-121, SC-122
  • Test and build greenness — SC-123, SC-124, SC-125
  • Migration guidance — SC-126, SC-127
• MODIFIED (0) · REMOVED (0) · RENAMED (0) — new domain; nothing destructive.

No destructive-merge guard or parent approval was triggered (zero REMOVED / zero MODIFIED). The new prometheus-charting domain is distinct from the existing web-ui canonical domain.

5. Final lifecycle status (all 8 phases done)

Phase	Status	Evidence
Proposal	✅ done	proposal.md
Spec	✅ done	flat spec.md (27) + domain delta specs/prometheus-charting/spec.md (27 ADDED)
Design	✅ done	design.md
Tasks	✅ done	tasks.md — 39/39 checked, zero - [ ]
Apply	✅ done	3 slices delivered (commits 5dad982, 65bae95/58be6e0, 67ca0fc/ba94317)
Verify	✅ PASS	verify-report.md — 26/27 PASS, SC-125 PARTIAL→PASS; gates green
Sync	✅ done	sync-report.md — SYNCED; canonical prometheus-charting domain created
Archive	✅ done	this report + folder move performed

6. Gate results (run at head 67ca0fc; per verify-report)

Gate	Command	Result
Backend tests	cd backend && PYTHONPATH=src python3 -m pytest -q	PASS — 293 passed (2 pre-existing warnings)
Backend lint	cd backend && PYTHONPATH=src python3 -m ruff check src tests	PASS — All checks passed
Frontend build	cd frontend && npm run build	PASS — exit 0 (pre-existing chunk-size warning)
Frontend lint	cd frontend && npm run lint	PASS — 0 errors (1 pre-existing warning)

7. Carry-over follow-ups (non-blocking; recorded per task)

1. [INFO] Stale generated .pi-map.md still references Grafana — generated project-map artifacts (.pi-map.md / .pi-map.index.md) still mention Grafana / ObservabilityPage.tsx / GrafanaLinkWidget. These are generated artifacts, not deliverable source, and are explicitly ignored by SC-115/SC-116 (which scope only backend/src/frontend/src source). Out of scope for this change — regenerate via project_map_patch / project_map_validate in a separate housekeeping pass; the project-map protocol already flags these dirty.
2. [INFO] SC-125 was PARTIAL→closed. Verify found SC-125 (new widget kinds have tests) PARTIAL because no explicit isLoading:true loading-state test existed in any of the three Prometheus widget test files — a coverage gap, not a functional defect. The gap was closed before archive: apply-progress.md documents adding one renders skeleton while loading case to each of PrometheusChartWidget / PrometheusGaugeWidget / PrometheusMeanWidget, asserting the Skeleton renders under { data: undefined, isLoading: true }. SC-125 is now PASS.
3. [INFO] config.yaml context block still names frontend/src/components/ObservabilityPage.tsx (refactored away into service-tabs/). Not an SC-121 criterion (which targets the charting/grafana claims — those are fixed); minor doc staleness. Out of scope.
4. [INFO] Slice-2 review-budget variance — slice 2 (~707 insertions) exceeded the ~310–400 forecast, but is additive feature code + tests (gauge + mean); the boundary is the feature, not scope creep. Non-blocking; recorded for the record.
5. [INFO] Unrelated dirty working-tree items predating/orthogonal to this change (an uncommitted cosmetic reformat of frontend/src/pages/service-tabs/MediaTab.tsx, untracked .pi-tmp/*, and the separate service-storage-harness proposal folder) were not touched by this archive. SC-127 (independence from service-storage-harness) holds.

8. Residual risks & destructive-merge statement

• Destructive sync / merge: not applicable. Zero REMOVED and zero MODIFIED requirements (new prometheus-charting domain; pure ADDED). No destructive-merge guard or parent approval was triggered.
• Backend / data-contract impact: none — Grafana was fully excised from live code paths (service type, adapters, widgets, hook, API client, type, status endpoint, nav entry, service tab); Prometheus is the direct chart source via /api/v1/query_range. The metric widget data shape is preserved. Archive touched only OpenSpec docs + the folder move.
• No critical verification issues remain (CRITICAL issues are non-overridable; the one verify CRITICAL was the reconcilable checkbox/apply-progress gap, now resolved).
• No browser/visual smoke was performed (out of scope); the recharts RadialBarChart gauge and LineChart rendering are structurally tested only.
• Memory observation IDs: none — artifactStore: openspec; traceability lives in the filesystem archive + canonical spec.

9. Move performed

git mv openspec/changes/prometheus-direct-charting openspec/changes/archive/2026-07-08-prometheus-direct-charting

• All 9 artifacts confirmed present at the archived path: proposal.md, spec.md, specs/prometheus-charting/spec.md (delta), design.md, tasks.md, apply-progress.md, verify-report.md, sync-report.md, archive-report.md (this file).
• Canonical openspec/specs/prometheus-charting/spec.md remains in place (verified untouched after the move). openspec/specs/web-ui/spec.md also untouched.

Appendix — Files written/moved by this archive (OpenSpec only; no source code)

• Written: openspec/changes/prometheus-direct-charting/archive-report.md (this file) — at the active path before the move; travels with the move into the archive.
• Moved (via git mv): the entire openspec/changes/prometheus-direct-charting/ directory → openspec/changes/archive/2026-07-08-prometheus-direct-charting/.
• Left in place (durable canonical): openspec/specs/prometheus-charting/spec.md.
• Not committed / not pushed — the parent owns the commit with explicit paths.
