docs(claude): record owner norms — selector questions, stacked PRs, KYAML / I-JSON+JCS / UUID v8

[hyperpolymath]

Summary

Appends an "Owner norms (2026-10-14)" section to .claude/CLAUDE.md for agent sessions in this repository. echidna and proof-burrower get the same text.

Changes

• Decisions are asked with the selector tool.
• Work lands as stacked PRs.
• Findings are fixed at source before any baseline entry. The exemption ratchet rejects ledger growth unless a Ratchet-exception: line names that ledger.
• The format standards point at their normative source in hyperpolymath/standards rather than restating it:
  • 3-practice/YAML-POLICY.adoc §3.4: KYAML, .kyaml (D280, D307, D293);
  • the workflow gate in standards#1025;
  • 3-practice/JSON-POLICY.adoc: I-JSON as JCS plus a final LF (D306);
  • ADR-008: UUID v8 profiles T and C (D305, D305b, D320).
• The UUID rule is scoped: src/ids.rs still mints records as v7 and content ids as v8 over JCS bytes. Profiles T and C, and the ban on new v7 minting, apply once the ids.rs migration lands. This is the wording the owner accepted on proof-burrower#111.

The CI fix this PR used to carry (ported from #180: the echidna_core::trust::axiom_tracker import in tests/live_echidna.rs and quinn-proto 0.11.19) is now on main via #180 itself, and the workflow-linter change via #181. Since the merge of main (0c7f846), this PR changes .claude/CLAUDE.md only.

The repo's migration to these formats, including the store's content ids moving to profile C, follows in its own stacked PRs.

📝 Summary

Summary by CodeRabbit

• Documentation
  • Added guidance on requesting decisions, structuring reviewable changes, and addressing findings at source.
  • Documented estate-wide formatting conventions and exceptions.

The repository guidance adds owner norms for decision requests, pull request stacking, and findings. It also sets estate-wide requirements for YAML, workflows, JSON, UUIDs, and formats retained for uncontrolled consumers.

Changes: Repository guidance

Layer / File(s)	Summary
Owner norms .claude/CLAUDE.md	Adds guidance to use structured options when requesting decisions, submit independently reviewable stacked pull requests, and fix findings at their source.
Format requirements .claude/CLAUDE.md	Adds requirements for YAML and workflow formats, JSON serialisation, UUID profiles, and documenting exceptions for formats retained due to uncontrolled consumers.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~8 minutes

Change: Other

Merge Risk: 🔵 Low · up to 58130

The guidance overstates the governance rule and could confuse maintainers handling a declared exception. This is a localized documentation correction, not a major merge risk.

### Architecture Summary

Architecture risk: 🔵 Low · up to 58130

The changed surface does not map to a changed system, dependency edge, entrypoint, or external dependency.

Changed systems: None identified.

Architecture concerns
No architecture-level concerns identified.

Review details

Before / after behavior

• observed — Modified behavior in .claude/CLAUDE.md: Adds owner norms covering structured decision requests, stacked PRs, and fixing findings at their source rather than expanding baselines or ledgers.
• observed — Modified behavior in .claude/CLAUDE.md: Adds estate-wide format requirements: KYAML for YAML and workflows subject to the specified gate and lockfile restrictions; JCS-serialised I-JSON with one final LF for JSON; UUID v8 with distinct time-ordered and content-id profiles; and retaining other formats only for uncontrolled consumers, with the reason recorded beside the file.

documentation to specify that it rejects undeclared ledger growth, while
