# /edit-contract — Bounded Chapter Edits
One file per contract at `contracts/{chapter}-{slug}.md`. No other ledgers.
## When to use
Before a substantive edit (rewriting more than one paragraph, changing what a
section claims, restructuring). Not for typo fixes or single-sentence edits.
## Contract file format
```markdown
# Edit Contract: {chapter} — {short goal}
## Spine card
- Section role: {what this section must keep doing in the argument}
- Core claim (must not broaden): {one sentence}
- Sources in scope: {list; their roles — support / background / challenge}
- Forbidden: {claims that must NOT appear; scope that must NOT leak in}
## Scope
- May change: {files/sections}
- Must not change: {adjacent sections, quoted spans, other chapters}
## Attempts
- [ ] Attempt 1: {date} — {outcome: accepted / revise / rejected, one line why}
- [ ] Attempt 2: …
- [ ] Attempt 3: …
```
## Workflow
1. Draft the contract from the user's request and the current section; show
it; the user approves or amends it **in conversation** before any edit.
2. Make the edit within Scope. After the edit, restate in one short table:
what changed, whether the core claim broadened (quote before/after if it
did), and whether anything Forbidden appeared.
3. Record the attempt line. The user's accept/revise/reject decision in
conversation is the gate — the file records it, it does not grant it.
## Three-strike escalation
After **three recorded failed attempts on the same contract** (not before —
a single "this is unclear" is feedback, not an escalation trigger): stop
patching. Diagnose which it is — underspecified request, wrong scope (needs
section-level restructure, not a patch), evidence gap (the claim wants
support the sources cannot give), or drifted spine — and offer: (a) rewrite
the contract, (b) escalate scope deliberately, (c) drop the change. Do not
produce a fourth patch under the old contract.
## Constraints
1. One contract file per edit goal; append-only Attempts.
2. Never edit outside Scope; never touch quoted spans.
3. In P0 this discipline is advisory prose; the P1 guard enforces Scope and
the attempt count from the session log. Do not describe it as enforced.
4. No emoji. British English.
