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 3754 files.
• npx vitest run --project domain --project services: 7769 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 renamed book renewing a sent version_id and its chapters' ids is served with unique and renewed rules; two creates sending a handle stored as code and embedded in link are served with copy and template rules.
• Serving: each served update gets a fresh version and new chapter ids that keep their titles; a served create with a new handle stores it as the code and rebuilds the link.
• Unit: the explanation, including a UUID another entity holds (not unique), a child row whose text changed (not renewed), and a member copied only in part (still fixed); the renewal helpers; applying both update rules.
• The four gate and serving tests fail on 43d98ea9.
• Review round (on a477b21d, where each fails): serving renews only the UUIDs at the pointers the recording renewed, keeps an author id each chapter names, gives one UUID the same replacement in every renewed field, and gives no rows to an entity that holds none; a recorded call that keeps a renewed value refuses the plan; a renewal that keeps, moves or borrows a UUID is not one; a copied member is type-checked against its stored field; a member stored otherwise under its own name is not accepted; an echoed value's copy is no template source; a sent UUID stored in another letter case is not a generated one.

Pilot recordings

Each application was reset, then recorded with the capture's reads and, per write target, two scratch objects whose every write was read back at once (item and list), deletes read back as 404.

Application	Write	Before	After
Shlink	post_rest_short_urls	unexplained-change	served
n8n	patch_rest_workflows_by_workflow_id	unexplained-change	served
Mealie	patch_recipes_by_recipe_id	unexplained-change	unexplained-change

No other verdict of the six recordings changed. Mealie's update was served by an earlier version of this branch with recipeIngredient renewed. Each of its two recorded updates keeps the ingredient ids; the gate's copy of the second recipe held the first recipe's ids, because the read that showed it was the create's observation and was not adopted. Each renewed field now needs every recorded call to renew it, so the plan is refused rather than served regenerating ingredient ids. Built on the list-query stack (#5800 with #5699 merged), the held-out sessions agreed on two more steps each for n8n (127 to 129 of 143) and Shlink (126 to 128 of 137) with the earlier version; Komga, NetBox and Sentry were unchanged.

Published captures

• Over the 50 published captures, every write verdict is unchanged: 31 served write tools. The only plan that changes is Shlink's unserved create, which now accepts customSlug and templates shortUrl.
• An earlier version also made echoed values template sources. It templated Grafana's folder url around uid (the URL also holds a slug of the title) and BookStack's page HTML around its markdown. Echoed values are no longer sources.
• The served smoke applies all 31 served write tools, as on 43d98ea9.
