Audit: R76.S2 — Seal-audit staging file
Task: R76.S2 — Create .agents/spawns/r76-phase-0-to-1-bridge/seal-audit.md placeholder for Sigma Phase B.
Branch: feature/r76-s2-round-card
Worktree: E:/AMS/.worktrees/claude/r76-s2-round-card
Main at start: 7c6fc8e9 (post R76.P3 merge)
Date: 2026-04-18 (Wave 4 ceremony track, sibling to S1 session-seal)

2. Governing contract
Sigma orchestrator contract: docs/agents/sigma-orchestrator.md §4 Phase B mandates Sigma produce .agents/spawns/rNN-<theme>/seal-audit.md during the seal step, capturing audit_verify_chain + merkle_finalize + merkle_root outputs.
R76.S2’s job is to stage a placeholder with the structural scaffolding pre-filled so that Phase B sealing is a fill-in-the-blanks operation rather than a doc-authoring operation.

Phase B — Sigma seal
Not yet run. Phase B populates this document’s TBD fields after audit_verify_chain + merkle_finalize + merkle_root.
Total: 9 merged T3 PRs (H1–H6 + P1–P3) + 1 Phase A PR (#152) = 10 merged + 2 Wave 4 pending.
4. Constraints to honor
- Do NOT fill TBD values. Merkle root, seal commit SHA, Wave 4 merge SHAs belong to Sigma Phase B.
- Do NOT touch
docs/session-seal-s8.md. That is R76.S1’s file. - Do NOT touch
.agents/spawns/r76-phase-0-to-1-bridge/manifest.md. Already merged in PR #152. - Do NOT touch
src/. Docs-only task. - CLAUDE.md §7 ordering rule: final
thought_recordmust precedemerkle_finalize— reflect in the §4 acceptance claims. - Worktree-only edits. Never touch main checkout.
unset GITHUB_TOKENbefore anygit push.
5. Risk register
| Risk | Mitigation |
|---|---|
| TBD fields accidentally filled | Explicit “staging document” banner + section 5 reminder |
| PR table SHAs drift between audit and implement | All 9 merge SHAs captured here; cross-reference at Step 4 |
| Wave 4 sibling (R76.S1) collides | No file overlap — S1 writes docs/session-seal-s8.md, S2 writes .agents/spawns/...seal-audit.md |
| Frontmatter breaks gray-matter | merkle_root: TBD is a valid YAML scalar; quote if any colon-containing strings sneak in |
| Test gate regression | Docs-only change; 1085/1085 tests should pass unchanged |
6. Exit criteria for audit step
- Confirmed manifest exists (
8130 bytes, PR #152) - Confirmed no
seal-audit.mdyet - Captured 9 merge SHAs for Wave map via
gh pr list - Confirmed no existing
r76-s2-round-card-*docs - Sigma orchestrator contract §4 Phase B referenced as governing authority
Proceeding to Step 2: contract.
