Verification

Executed on macOS with Node v22.23.1 on this branch with the write-plan branch's head 45a5c8b9 merged in. The pilot recordings were made against live applications on six disposable Linux VMs, each restored from a snapshot first.

Gates

• npm run build:cached, npm run check:fast (typecheck and lint, no warnings in the changed files), npm run format:check, npx knip, npm run scan:todos, npm run docs:check, npm run verify:test-discovery and npm run mcp-catalog:check: passed.
• npm run jscpd: 3.43% duplicated lines over 3753 files.
• npx vitest run --project domain --project services: 7755 passed, 5 pre-existing skips.
• npm run test:prepare, then npm run test:focused -- the environment serve and export CLI boundaries, the serve and served-writes MCP boundaries, the analysis-view CLI and MCP boundaries, the compact input schema boundary and tool schema validity: 8 files, 79 passed.

Tests

• Gate: a list that spells clocks +00:00 where item reads spell Z learns both spellings, the item view learns none, and a create read back by both is served; a create whose clock has a fraction is served where the list's spelling was learned from whole seconds; a list that spells a field both ways, at the stored instant or another, learns nothing.
• Serving: a served create lists with the list's spelling and reads back with the item's.
• Unit: re-spelling keeps a value's fraction digits at any offset and across a date change, pads them to the format's width without dropping any, and formats an epoch spelling from the instant; an epoch value's milliseconds become fraction digits.
• Schema: a view clock spelling wider than nine fraction digits is refused.
• The gate and serving tests fail on 264ce410, the write-plan head they were written on.

Pilot recordings

Mealie's recipe reads spell clocks Z and its recipe list +00:00. On this branch alone the list line the create is read back on keeps its recorded members, so the create stays unserved; per-line list membership and list queries (#5787, #5800) answer that line from the state. Built on the list-query stack (#5800 with #5699 merged):

• Mealie's post_recipes goes from contradicted to served, and Mealie's held-out sessions agree on 298 of 310 steps, up from 294.
• With the assigned-values branch (#6136) too, all three Mealie write tools are served, at 302 of 310.
• The other five applications are unchanged.

Published captures

• Over the 50 published captures, one view learns a spelling: Mealie's recipe list (dateUpdated, createdAt, updatedAt). Every write verdict is unchanged.
• The served smoke applies all 31 served write tools.
