This file reserves session ID 0008 for engineering. The driver replaces this body with the full transcript and renames the file to its final SESSION-0008.0-TRANSCRIPT-2026-06-10T08-40--.md form at session end.

Launch prompt

Let's flesh out the Solution Design template and documentation to include other sections like Operational plan, where Documentation will live, what new or updated documentation is required (including public-facing docs), Observability, Business Success Metrics (and how they'll be measured), Product Success Metrics (and how they'll be measured), Monitoring (alerts/monitors), Telemetry (not necessarily in that order). What other gaps are there?

Plan

Anchor: direct operator instruction extending the canonical Solution Design standard (no upstream issue/design exists for the standard itself — the doc is the source of truth, §4.1). Continues branch docs/solution-design-pain-points-business-framing.

1. Extend solution-design/GUIDE.md + TEMPLATE.md with four new top-level sections after §7 Delivery Plan:
   • §8 Success Metrics & Measurement — business metrics (operationalizing §1.6 outcomes, which gain BO-n IDs) + product metrics (PM-n), each wired to its measurement source.
   • §9 Telemetry, Observability & Monitoring — telemetry events (TEL-n), logs/metrics/traces + health + dashboards, SLOs (SLO-n) and alerts (ALR-n).
   • §10 Operations — operational plan (runbooks RB-n, who operates), support & incident response, maintenance & lifecycle (patching, backup/ restore, cost, deprecation). Also the home of a non-software solution's operational plan.
   • §11 Documentation plan — where docs live, new/updated docs (DOC-n) incl. public-facing, docs as part of slice DoD.
2. Gap-closes beyond the asked-for list: §6.10 Migration & compatibility; data retention/deletion in §6.6; launch comms/docs-ready gate in §7.3; Metric column in the traceability matrix.
3. Renumber old §§8–10 → §§12–14; update all internal cross-references ("keep §§8–10", non-software replacement rule).
4. Sync handbook README §3.3 section table.
5. Commit on this branch; PR + merge per posture.

Outcome (checkpoint after merge)

• Working branch rebased onto origin/main (the session's checkout was 28 commits stale; conflicts with the E2E/pipeline edits in GUIDE/TEMPLATE §§6.8/7.2/7.3 and the section-by-section authoring convention resolved by combining both sides).
• Shipped as PR #31 (merged 2026-06-10T15:51Z): wiggleverse/engineering#31
  • 2a8a75c Solution Design: operability back matter — metrics, telemetry, operations, docs (§§8–11) — GUIDE.md, TEMPLATE.md, README.md §3.3 table.
  • f1b639a app.json: engineering repo also carries content (stray change adopted from the prior session's working tree).
• Gaps deliberately NOT added (scale judgment, logged for the operator): i18n/localization, legal/compliance review, experimentation/A-B testing, pricing/packaging implications, formal threat model — each can join §6.6 or §1.8 when an app first needs it.

Deferred decisions

• Classified the opening prompt as planning-and-executing (not brainstorming): concrete edits to the standard's own docs, continuing the branch's prior work.
• Anchor: direct operator instruction (no issue/design exists for the standard itself); proceeded without the §8.5-gate eligibility script since there was no issue to check.
• Adopted + committed the stray app.json "content" change rather than leaving it uncommitted or discarding it (valid per schema 1.2).
• Renumbered template §§8–10 → §§12–14: section numbers are per-spec citations, so published specs citing the old numbers are unaffected, but any future tooling assuming "§8 = traceability" would need the new map.

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.
