M12-03H Status

status: done task: library reload replaces only the matching linked generation snapshot updated: 2026-08-17 America/New_York enablingTask: false parityStateChange: false

Scope

Schema-1 reload requests identify one SOURCE_LIBRARY and an expected generation/revision. The replacement must keep the same library identity, advance exactly one generation, advance the source revision, and retain a read-only source-library data-block closure. Only the unique matching snapshot is replaced; other libraries and other generations remain unchanged.

Malformed requests, duplicate state identities, owner substitution, skipped generations, and stale generation/revision requests fail closed before any Main mutation. A stale request returns REVISION_CONFLICT and an unchanged state.

Evidence

npm --prefix web run test:library-linked-reload passed 4/4 unit tests.
The matching-generation case replaces one snapshot atomically while preserving a future generation and an unrelated library; the input state remains immutable.
Stale, malformed, duplicate, owner-substituted, and non-adjacent reload cases are rejected without publishing a partial state.

Next Task

M12-03I: missing library preserves a placeholder and the original source reference.

Rollback

Remove the linked reload protocol, unit suite, manifest, package command, and this status entry. Restore M12-03G to pending and move the machine queue back to M12-03H. No parity ledger rollback is required.
