[Grok] Perfect ACM dao-shu guidance (unconstrained)

[KorenKrita]

Summary

Unconstrained perfect always-on ACM guidance: optimize for understanding quality, not the 8500 gate. Still anti-sprawl (single moments table, no Judgment duplicate, no dual ambiguous-base tips).

Design (道 + 术)

• 道: keep-live opening + working-set invariant (earns its place against this invariant)
• 识别: 4 smells; full lightest transition bridge; recognizable moments
• 判据: fold/rebase criteria + travel one-liner; cold start only on rebase candidate compare
• 恢复: failure shapes include corrective lean
• Disclosure: rebase-local skill pointer for ambiguous bases; end pointer for archive/exception only

vs #8 / #9

	#9	#8	This
CORE length	8496	8732	9088
keep-live opening	✅	—	✅
full bridge wording	compressed	✅	✅
against this invariant	—	✅	✅
cold start on fold anchors	—	mixed	❌ (rebase-only)
rebase inline skill	—	✅ + end duplicate	✅ without end duplicate
corrective failure shapes	thin	thin	✅

Recommend superseding #2–#9 after review if live eval agrees.

Test plan

• bun run verify:acm
• Live: smell → invariant → lightest transition → fold criteria; rebase ambiguous → skill loads from rebase section

Superseded by #12 (chosen merge target for ACM dao-shu guidance). Closing this alternative.
