Why

claim draft and ask currently ignore contradictions — a draft negating an approved claim is stored silently. F1 makes contradictions explicit and visible (status: conflict) without auto-resolution, closing a poisoning vector for local-first memory.

Follows mcp-v2-protocol-upgrade backlog F1 (ranked #1 by fit with trust model) — deterministic, no LLM/embed/network.

What

• At claim draft time, scan approved claims in workspace, normalize title+body+tags, apply 3 heuristics: negation flip, value swap, status change
• Record advisory contradicts: [{claim_id, heuristic}] in draft frontmatter (preserved via Parse/Render + digest)
• ask returns ready approved + conflict drafts side-by-side

Status

• Harness plan docs/plans/active/conflict-aware-drafts.md locked (01M0ZAT3BS4GS7X61V4ZZB9GY9, intake 01M0ZAYX27CD3EKSN1CWTPT4XE, lane normal, status: active)
• To-plan complete — 2 phases planned:
  • contradiction-detection (01M0ZBG7) — heuristics + metadata + draft wiring
  • conflict-surface (01M0ZBGR, depends contradiction-detection) — query + ask JSON status: conflict
• Source: docs/planning/CONFLICT-AWARE-DRAFTS.md (this PR) + harness plan

Checklist

Phase 1: contradiction-detection

• W1.T1 DetectContradictions in claim.go + table tests
• W1.T2 Contradiction type + frontmatter contradicts + round-trip + digest
• W2.T1 wire into ClaimStore.Draft / claim draft
• W2.T2 ScanWorkspace/Rebuild preserve contradicts

Checks: go test ./..., go vet, CGO_ENABLED=0 go build

Phase 2: conflict-surface

• W1.T1 TrustedQuery return drafts with conflict signal
• W1.T2 ask JSON status: "conflict"
• W2.T1 integration test: approved → contradicting draft → reindex → ready+conflict

Checks: go test -race, make smoke, git diff --check

Next Actions

1. work full phase contradiction-detection (next)
2. work full phase conflict-surface
3. check full → handoff → squash-merge

Harness

• Prior trusted-single-runtime abandoned (inventory mismatch, superseded by 0.3.x)
• mcp-v2-protocol-upgrade completed and moved to docs/plans/completed/
• Single active plan now: conflict-aware-drafts
