This file reserves session ID 0025 for engineering. The driver replaces this body with the full transcript and renames the file to its final SESSION-0025.0-TRANSCRIPT-2026-06-22T07-40--.md form at session end.

Launch prompt

Start F1 of the SDLC pipeline refactor — handbook reconciliation in
wiggleverse/engineering (issue #63 on the dev-claude-plugin tracker): §3.3
accretion, §4.3 slice-retirement (Feature = one SPEC = one plan = one execution;
Stories become standalone leaf issues, R2(b)), solution-design GUIDE/TEMPLATE
updates, and the documented home of the Claude-Design-vs-Code decision.
Source: engineering docs/sdl-pipeline-refactor-brief.md (decisions locked).
It's the docs-lead spine F2F5 cite — first.

Plan

Anchor: design docs/sdl-pipeline-refactor-brief.md (R2a — locked Solution-Design brief; eligibility ELIGIBLE). Work repo: wiggleverse/engineering. Feature #63 on the dev-claude-plugin tracker. Branch: feat/sdlc-f1-handbook-reconciliation.

F1 — Handbook reconciliation for the staged-gate SDLC pipeline. Reconcile the canonical engineering docs to the brief's locked decisions. F1 is the only Feature touching engineering (F2F5 are dev-claude-plugin), so the full handbook sweep happens here or never — internal consistency is required, not optional.

Deliverables (per brief §F1):

  1. §3.3 accretion (README) — the Solution Design is authored by ACCRETION: each design-track lens (business → product → engineering) is written into the same growing SPEC at its own gated stage; never separate brd.md/prd.md files; one coherent doc superpowers:writing-plans consumes. Reframe the Delivery row + traceability row (drop "Slice").
  2. §4.3 reconciliation (README) — Feature = one SPEC = one plan = one execution; its internal units are the plan's Tasks (not slices/Stories). Feature→Story(slice) sub-layer retired; Stories are STANDALONE leaf issues only (R2(b)). "Slice" is not used (superpowers grain: sub-project / spec / plan / Task / Step). R1R4 intact.
  3. GUIDE/TEMPLATE — accretion authoring model (replaces "drafted whole, reviewed whole"); §7 Delivery Plan = rollout/launch strategy only (retire §7.2 "Slicing plan" task-checklist; renumber 7.3→7.2, 7.4→7.3); relocate the **Design:** field to §5.1 (Product lens, with the Claude-Design-vs-Code decision); drop "Slice" columns from traceability + docs tables.
  4. Claude-Design-vs-Code home — keep §5.1 (Product/prd lens) as the documented home; note the decision is authored at the prd-lens stage under accretion.
  5. Full slice sweep across README §4 day-to-day, §7 roadmap, §10, lifecycle tree.

Then: verify (residual-slice grep + internal §7.x ref check) → commit → PR → merge. No engineering version bump (handbook, not a semver'd plugin). No code/tests/PPE (docs-only; the pipeline's E2E/PPE gates don't apply to a prose change).

Deferred decisions

Autonomous-mode low-confidence calls the driver made and would have liked operator input on. Appended as the session runs; surfaced at finalize. Empty if none.

  • Full-handbook slice sweep (scope). The brief's F1 item enumerates §3.3/§4.3/ GUIDE/TEMPLATE/claude-design-home, but "slice" is load-bearing in README §7 (roadmap) and §4 too. Since F1 is the only engineering-touching Feature, I swept all of them for internal consistency rather than leaving §7 contradicting a slice-retired §4.3. Confidence high (forced by the decomposition), logged for visibility.
  • **Design:** field relocation + plugin lag. Retiring per-slice §7.2 leaves the shipped **Design:** field (consumed by wgl-design-handoff + the design-readiness soft gate, which read it per---slice) without a slice home. I relocated it to the SPEC's §5.1 (Product lens), co-located with the Claude-Design-vs-Code decision — one SPEC = one design decision. The plugin's --slice-grained plumbing (backfill-spec-design.sh, design-readiness.sh) now lags the docs and needs a downstream reconciliation (candidate: F5 wiring / a follow-up issue). Flagged, not fixed in F1 (docs-lead-automation, §4.1).
