Track: gh-aw-dev branch ready for merge — remaining items #1659

Status

PR #1658 (gh-aw-dev → dev) is open with 19 commits implementing epic #1648 (full planning lifecycle).

E2E test round 2 passed on squad-planning-e2e-2:

• ✅ Cast preserved across lifecycle runs (Firefly universe)
• ✅ Research → Plan → Accept fast path works end-to-end
• ✅ 16 issues created with sizing in body, dependency refs, native sub-issues
• ✅ Idempotent re-activation (zero duplicates)
• ✅ create-milestone safe-output error resolved

What's in the PR

Remaining before merge

• Verify HTML lifecycle markers appear in squad-planning-e2e-2 comments (truncated in review — need full body check)
• Decide: merge as-is, or split squad.md (2112 lines) into shared/plan-modes.md first?
• Resolve whether owner: lead in issues should map to cast names (owner: zoe) — currently uses generic role names
• Update PR feat: Evolve Squad planning into executable SDLC lifecycle (#1648) #1658 description with final commit count and test evidence links

If splitting squad.md (optional, deferred)

1. Extract planning modes into workflows/shared/plan-modes.md
2. Keep squad.md as routing/parsing layer (~800 lines)
3. Validate gh aw add still compiles with split imports
4. If markers still missed → per-mode files (~100 lines each)

Test evidence

• Round 1: bradygaster/squad-planning-e2e — found 5 bugs, all fixed
• Round 2: bradygaster/squad-planning-e2e-2 — fast path clean, cast preserved
• Latest commit: af6df2f6 on gh-aw-dev
