chore(release): v2.7.0 — AGPL-3.0 + discipline-skills + governance ratchet + Fable 5

[tigers1997]

Summary

Bundle release of PRs #59–#82, spanning 2026-05-24 → 2026-06-17. The release cut was prepared 2026-06-12 and stalled locally; shipping now after a clean 2.1.176–181 upstream survey confirmed no forced changes (subagent-nesting hold is now resolved upstream but is handled in a follow-up PR for clean separation).

Key tracks

• AGPL-3.0 relicense with the discipline-skills MIT carve-out
• discipline-skills module (curated 7-skill fork of obra/superpowers)
• Contributor-governance ratchet (branch protection, CLA, AI-review verdict gate)
• Adjacent-project dogfood cascade (hook-group union merge, persona-drift [ NOTICE ], --modules +x/-y, retrofit-byproduct gitignore, manifest written_by_sha + --whats-new)
• Doc-cleared hook-payload batch + block-dangerous-bash $HOME hardening
• CC 2.1.155–2.1.175 compat surveys (incl. the agent schema-status correction)
• Fable 5 as the default model throughout (scaffolded settings + intake field + test-runner agent; own-CI reviewer briefly pinned to Fable then walked back to claude-sonnet-4-6 on cost in chore(ci): repin own-CI reviewer to claude-sonnet-4-6 (cost) #82)

Mechanical

• CC_VERSION 2.6.0 → 2.7.0
• Restores ## [2.6.0] section header accidentally deleted in PR chore(governance): ratchet branch protection + export ruleset (#3 of 3) #67 merge (it had folded the 2.6.0 entries back into Unreleased, over-reporting in --whats-new)
• Adapts test/cc-manifest/test-whats-new.sh case C to the empty-Unreleased state a fresh release legitimately produces (first release since the test shipped; it had asserted Unreleased was non-empty)

Claude Code compat: 2.1.116–2.1.150 (unchanged — SchemaStore sync gate PR #5723 still open/draft, no tested_up_to bump per the no-lone-bumps rule).

See CHANGELOG.md § [2.7.0] for the full bullet detail and per-PR breakdown.

Test plan

• python3 configure.py --check clean (12 modules, 84 files scanned, compat 2.1.116–2.1.150)
• bash test/cc-manifest/test-whats-new.sh PASS (all four cases A–D)
• CI check green
• CI verdict-gate green (AI-review informational)
• CI license/cla green

After merge: tag v2.7.0 on the squash-merge commit + GitHub release with Claude Code compat: line per the release flow.

VERDICT: PASS

Tight release-cut PR: version bump to 2.7.0, CHANGELOG section restoration for the accidentally-dropped ## [2.6.0] header, and a test-case C update that correctly relaxes the Unreleased-must-be-non-empty assertion for the post-release boundary condition. All three changes are directly related to the release act. No new third-party code, no schema keys added, no persona snapshots touched, no unrelated changes.
