Sync Report — prometheus-direct-charting

Phase: sync · Change: prometheus-direct-charting · Repo: /home/user/manage Mode: file-backed (artifactStore: openspec). No source-code edits; only OpenSpec artifacts were written. Not committed (parent owns the commit). The change folder was not moved (that is sdd-archive's job).

Status: SYNCED. A new canonical domain openspec/specs/prometheus-charting/spec.md was created from the verified change, and the change-side domain delta spec that unblocks the native status engine's sync/archive gates is also in place.

---

1. Executive summary

The prometheus-direct-charting change shipped a complete but flat openspec/changes/prometheus-direct-charting/spec.md (27 requirements, SC-101 … SC-127) with no per-domain delta spec under openspec/changes/prometheus-direct-charting/specs/<domain>/. sdd-sync requires a domain delta spec; the flat spec alone does not satisfy the canonical-merge contract.

Verify already returned PASS (verdict in verify-report.md; all four gates green — backend pytest 293 passed, ruff clean, frontend npm run build exit 0, npm run lint 0 errors). Functional coverage was 26/27 fully PASS, with SC-125 PARTIAL on test coverage only (loading-state test gap) — a non-blocking coverage finding, not a functional defect; the task framing treats it as PARTIAL→PASS after coverage close. The verify report's single CRITICAL was an archive blocker (19 unchecked task checkboxes + missing apply-progress.md); the apply-progress.md artifact now exists and that condition does not block sdd-sync of the green code.

This sync reconciles the flat-spec-vs-domain-spec gap:

1. Authored the missing change-side domain delta spec — openspec/changes/prometheus-direct-charting/specs/prometheus-charting/spec.md — using a clean ## ADDED Requirements structure that preserves the exact requirement IDs (SC-101 … SC-127) and text (including the patched SC-116 / SC-118 wording) from the verified flat spec.md. This is what flips the native status engine's specs artifact from partial → done.
2. Synced the end-state into the canonical store — openspec/specs/prometheus-charting/spec.md — the actual sync target. Because the canonical prometheus-charting domain did not previously exist, the native helper rule applies: when the canonical spec does not exist, the change spec becomes the new canonical spec. The two files therefore carry identical requirement bodies (delta under ## ADDED Requirements; canonical under ## Requirements), verified byte-identical for the requirement region.

Domain name prometheus-charting was chosen (per the dispatch brief) because it covers the full new model: direct Prometheus range-query charting, the gauge and mean modes, and the Grafana removal that established the new direct-query model. It is distinct from the existing canonical web-ui domain (MUI→shadcn migration — a different concern), which was not touched.

2. Structured status & actionContext findings

The native gentle-pi.sdd-status passed by the parent reports changeName: null with blockedReasons: ["Change selection is ambiguous: mobile-responsive-parity, prometheus-direct-charting, prometheus-direct-charting, service-storage-harness, services-as-hub-ia."] because the engine auto-detected four active changes. This sync task was explicitly assigned prometheus-direct-charting; the ambiguity is a parent-resolution artifact and does not block this phase (isNonAuthoritative: false).

• artifactStore: openspec; change root openspec/changes/prometheus-direct-charting/.
• Artifacts present: proposal.md, spec.md, design.md, tasks.md, verify-report.md, apply-progress.md.
• verify: PASS (verify-report verdict; gates green at 67ca0fc).
• actionContext: mode: repo-local, workspaceRoot: /home/user/manage, allowedEditRoots: ["/home/user/manage"], warnings: []. All three files written are inside the authoritative workspace / allowed edit roots. ✓
• relationships.sameDomainActiveChanges: [], collisions: [] — no active same-domain collisions, so no archive/sync ordering decision was required.
• The new prometheus-charting domain is distinct from the existing web-ui canonical domain; openspec/specs/web-ui/spec.md was left untouched.

Post-sync structural change: openspec/changes/prometheus-direct-charting/specs/prometheus-charting/spec.md now exists (hasDomainSpecs → true), resolving the missing-domain-spec condition that gated sync. The flat spec.md is intentionally left in place as the authoritative planning artifact the work was built against (the archive convention keeps flat specs too); it no longer triggers the "flat spec without domain specs" condition now that a domain delta sits alongside it.

3. Domains synced & canonical files updated

Domain	Change-side delta (source)	Canonical (sync target)	Action
prometheus-charting	openspec/changes/prometheus-direct-charting/specs/prometheus-charting/spec.md	openspec/specs/prometheus-charting/spec.md	NEW domain — ## ADDED Requirements copied into canonical as a new spec

• Canonical file created: openspec/specs/prometheus-charting/spec.md (27 requirements).
• Change-side delta created: openspec/changes/prometheus-direct-charting/specs/prometheus-charting/spec.md (27 requirements, all ## ADDED Requirements).

4. Requirement delta (ADDED / MODIFIED / REMOVED)

• 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) — none (new domain; no pre-existing canonical requirements to replace).
• REMOVED (0) — none.
• RENAMED (0) — none (RENAMED is intentionally unsupported by the native delta helper; not used).

5. Guardrails, approvals & destructive-sync assessment

• Same-domain collisions: none (sameDomainActiveChanges: [], collisions: []). The new prometheus-charting domain does not overlap the existing web-ui canonical domain. No ordering decision was needed.
• Destructive sync: not applicable. There are zero REMOVED requirements and zero large MODIFIED blocks (new domain; everything is ADDED). No destructive-sync parent approval was required for this sync beyond the explicit reconciliation instruction in the task.
• Legacy flat spec: detected pre-sync; resolved by adding the domain delta spec alongside it (the block condition is specifically "flat spec without domain specs"). The flat spec was left in place as a planning artifact.
• web-ui canonical isolation: the existing openspec/specs/web-ui/spec.md (the MUI→shadcn rework) was not modified — verified untouched by git status (mtime 2026-06-17T19:11, not in the modified set). The two domains are independent.

6. Validation / checks performed (file-backed, read-only)

Run from /home/user/manage (no source edits, no test re-runs — those are owned by verify and were already green at 67ca0fc):

Check	Command	Result
Canonical store populated	ls openspec/specs/prometheus-charting/spec.md	present ✓
Change-side domain spec present	ls openspec/changes/prometheus-direct-charting/specs/prometheus-charting/spec.md	present ✓
Requirement-ID parity (flat ↔ delta ↔ canonical)	grep -oE 'SC-[0-9]+' all three files, sort -u	27 == 27 == 27, identical IDs SC-101…SC-127 ✓
Body-text parity (delta ↔ canonical)	diff of the ^### Requirement: region of both files	identical ✓
Patched SC-116 wording present	grep "service-tabs/" both delta + canonical	present in both ✓
Patched SC-118 wording present	grep "service-tabs/LinksTab.tsx" both delta + canonical	present in both ✓
Delta is pure ADDED	count ## ADDED/MODIFIED/REMOVED/RENAMED Requirements	ADDED=1, MODIFIED=0, REMOVED=0, RENAMED=0 ✓ (no destructive sync)
web-ui canonical untouched	git status --porcelain openspec/specs/web-ui/spec.md	empty (not modified) ✓
No edits outside openspec	git status --porcelain (filtered)	only openspec/specs/prometheus-charting/, openspec/changes/prometheus-direct-charting/specs/, and this report added; pre-existing dirty/untracked items unrelated to this sync unchanged ✓
Markdown validity	write-time lint	all three files "Markdown clean" ✓

7. Carry-over items for the archive summary

These verify-phase findings are non-blocking for sync and should land in the archive summary:

1. [INFO] SC-125 was PARTIAL in verify (no explicit isLoading:true loading-state test in any of the three new widget test files — coverage gap, not a functional defect). The task framing treats this as PARTIAL→PASS after coverage close; if a loading-state case per widget has not been added, sdd-archive may want to confirm or note it.
2. [CRITICAL-process, archive-only] Unchecked task checkboxes. At verify time, 19 implementation / verification task checkboxes (Slice 3 §3.1–3.14 and Integration §4.1–4.5) were unchecked and apply-progress.md was missing. apply-progress.md now exists (created after the verify pass); sdd-archive should re-scan the native status engine to confirm tasks: done / applyProgress: present before moving the change to archive, and tick any remaining unchecked boxes if needed.
3. [INFO] Stale generated .pi-map.md files still reference Grafana / ObservabilityPage.tsx (generated artifacts, not deliverable source; ignored by SC-115/116). Regenerate via project_map_patch / project_map_validate.
4. [INFO] Slice-2 review-budget variance (~707 insertions vs ~310–400 forecast) — additive feature code + tests; boundary is the gauge+mean feature, not scope creep. Non-blocking; record in the archive summary.

8. Next recommended phase

→ sdd-archive (clean). Confirm the native status re-scan reports specs: done / sync: ready / archive: ready, then move the change to openspec/changes/archive/YYYY-MM-DD-prometheus-direct-charting, carrying over the items in §7 into the archive summary. Do not commit or push — the parent owns the commit with explicit paths.
