VC-01 / VC-02 cross-case assessment

Codex self-review, 2026-09-25. Inputs: transactional administration and offline field notes. Both are synthetic; the comparison is a hypothesis test in prose, not independent validation.

Decision VC-01 VC-02 Consequence for the language
First acknowledged boundary Server accepts a valid command Local recoverable commit “Saved” needs an explicit scope
Local editing Unaccepted proposal Locally authoritative revision after commit Local state does not imply local authority
Remote divergence Reject stale proposal; retain intent for review Preserve divergent revisions for reconciliation Shared concern, different acceptance histories
Response loss Outcome unknown until operation-specific evidence Propagation unacknowledged; local commit remains valid Pending synchronization and pending mutation are not synonyms
Retry Same command identity under bounded contract Same propagation identity under receiver contract Retry identity is a shared prerequisite, not yet an admitted pattern
Refresh Server observation must not erase a draft Incoming revision must not erase unresolved local work Preservation connects the cases without equating their storage guarantees
Single writer branch Domain validation and uncertain outcomes remain Conflict-copy path can be omitted Remove mechanisms only when their motivating force disappears

Q02 remains open but gains a precise counterexample to “local state means local authority”: VC-01 keeps local drafts while server acceptance controls shared records. Q03 remains open: server API evidence does not establish independent frontend uses. Q04 remains unknown: both plain narratives already express the obligations. An independent reviewer must judge whether names expose omissions or improve decisions.

Provisional relations: Local Draft State supports Version-Checked Mutation recovery; Mutation Outcome Tracking distinguishes acceptance from Invalidate and Reproject freshness. Across cases, draft preservation resembles Conflict Copy's preservation of intent, but neither requires the other's exact mechanism. These are editorial connections, not canonical graph edges or evidence of recurrence.

Keep the structure stable for the next cycle. Seek implementation evidence for the weakest new claim (unknown-outcome recovery), then an independent comparison of both cases. Rendering/addressing can follow as a bounded new branch after that review; a graph export or broader schema would not resolve the current evidence gaps.
