Stage 1: record the #1550 decision walk-through (classification, reclassification, dissent) in decisions/ #1685

Written-by: Chief

Second Stage 1 slice of #1550: the dogfood record Stage 1's own acceptance asks for. #1680 published the Project State files; this slice writes down the decision walk-through that used them, including the reclassification, so the loop has a worked example instead of a claim.

Scope — one new record under decisions/

• decisions/1550-stage-1-dogfood.md in the format decisions/README.md defines: date, decision, classification and why, evidence, participants, dissent, status, resulting tasks.
• It records the real walk-through of Proposal: AI-led Project governance, unified board and Handoff-driven Workflow (five-stage plan) #1550: proposal raised → Triage classified it needs-human on 2026-10-28 (comment id 6495508222 is the owner decision thread that follows) → owner reclassified it on 2026-10-29 and removed needs-human → Chief opened Stage 1: publish the minimal Project State (PROJECT.md, ROADMAP.md, docs/governance.md, decisions/) #1680 → Add the minimal Project State: PROJECT.md, ROADMAP.md, docs/governance.md, decisions/ #1682 merged as c5ed512d → this record and the Stage 1 continuation.
• It must name the reclassification case explicitly: what Triage decided, why, who changed it, on what authority, and what evidence changed the answer.
• It states what a human had to do (the owner's approval and the label change) and what Chief/automation did on its own, because Stage 1's acceptance asks exactly that.
• If decisions/README.md keeps an index of records, add this one to it.

Explicitly out of scope: no change under core/ or plugins/, no new configuration key, no UI, no scheduler, no edit to AGENTS.md, and nothing about later stages.

Acceptance

• Every claim in the record is traceable to a comment, label change, issue or merge commit, with the number or sha written next to it — no reconstructed reasoning, no invented participant.
• The classification is one of ordinary / major / severe exactly as docs/governance.md defines it.
• npm run verify green at the tip; Docs-not-needed: in both the branch commit and the PR body.

The umbrella #1550 stays open: the body says Part of #1550 and the PR closes this issue only.
