Resolve the conflict between ADR-011 (tags-not-digests) and the security work
(digest pinning) with one coherent rule that respects ADR-011's stateless/stateful
split:
- Stateful → pin `tag@digest` (readable tag + integrity digest): legible diffs AND
tamper-evidence. Snapshots cover broken updates; the digest covers swapped images.
- Stateless → rolling tags (latest/stable); digest-pinning would defeat the rolling
design. Integrity rests on official/verified images + disposability.
Aligned across ADR-011 (decision 2), ADR-004 (image management), ADR-002
(supply-chain row), accepted-risk R1, the service checklist, and TODO 15.6.
TODO 16.7 marked decided.

ADR-013 sets how boma draws on AnsibleBaobabV4 without inheriting it:
translate-don't-transplant — V4 is evidence, never authority. It is a legitimate
source only of operational gotchas and working config snippets (re-derived on
boma's terms); never requirements, domain values, structure, or conventions.
Provenance stays transient (commits/conversation), durable docs stay clean. AI
consultation guardrails included. Resolves TODO 3.3 and 10.1.
Also bring ADR-011 (update management, Proposed draft) under version control:
- fix its "reuse V4's ntfy topics" line to "boma defines its own" (ADR-013)
- track its 6 open questions in TODO 16, plus a 7th: reconcile its tags-not-digests
pinning with the digest-pinning the security work now mandates (R1 / checklist /
15.6) — they currently conflict.
CLAUDE.md gains a V4 guardrail + ADR-013 pointer.
