The kit's `template/`: a complete, minimal Runic Gateway module a reader copies, renames, and runs before reading a chapter. Slice 0 landed the workflow that runs it; this is the tree that workflow was written against, so the `template` job arms itself with no edit to the guard. Installed into a real core it adds one public page at `/examplegame/status`, a nav row pointing at it, one API route described in an OpenAPI fragment core merges, one table created by an idempotent schema fragment and dropped by a purge file, and both lifecycle hooks. That is deliberately less than a real module does; what it is complete about is the shape — every seam used once, with the reasoning next to it. Four decisions, settled with the org lead: 1. **Public tier only, plus the lifecycle hooks.** §2.11.1 d1's "one public route", plus enough to show the whole vertical seam once. Admin and player tiers become worked examples quoted from module-uo in chapter 2 rather than two thirds of a tree the reader deletes on day one. 2. **The release workflow ships as a file, in BOTH flavours** — `.gitea/` and `.github/`. Neither runs where it sits (a workflow is only read from a repository root) and each arms itself when the reader's copy is its own repo. Packaging is the part of a module that cannot be guessed at, and the kit's audience is outside this org, so assuming Gitea would have been assuming our own deployment. Core installs from a URL and does not care where the release lives — only that the host is on the operator's `MODULE_SOURCE_HOSTS`. 3. **A rename checklist that CI verifies**, not a rename script. `template/README.md` carries the table; `scripts/checkRenameSites.js` holds it against the tree in both directions — an unlisted file that still carries the placeholder fails, and so does a listed file that no longer does. The second half is the one usually left out and the more valuable: a row that has stopped matching reads as instructions to edit something that is not there. Same rule core's identifier check follows about its own exemptions. It has its own ten-test suite, run by CI as `node --test`, because a check that has never been shown to fail is a check nobody knows the state of. 4. **A neutral invented game.** One deviation from the literal answer, forced by decision 3: the id is `examplegame`, not `example`. The checklist check is a text search, and `example` occurs in ordinary English ("for example") all over prose that is not a rename site — a placeholder that cannot occur by accident is what makes the check answerable instead of a source of false alarms someone learns to ignore. **The pin moves to the 1.4.0 bump** (website `edge` 1b692bf), which is what `template/module.json` declares as `coreApi`. Slice 0 pinned its parent, before 1.4.0 existed, so `checkCoreApi.js` arms for the first time here — it asserts EQUALITY, and its failing on the next contract bump is the system working. Also in CI: the client tests now run AFTER the build (two of them read the built chunk and skip without one — run first, the job reports green while asking nothing about the artifact that ships), and `check:swagger` verifies the committed fragment is current. ## The finding: an UPDATE that changes nothing does not touch ON UPDATE CURRENT_TIMESTAMP Every suite passed, both guards passed, the chunk built, the module loaded into a real core and the page rendered correctly. Two hours later the same page said the world was offline, and it was wrong. `updated_at` was declared `ON UPDATE CURRENT_TIMESTAMP`, and MariaDB fires that only when an UPDATE actually CHANGES a value. The boot refresh writes the same numbers every thirty seconds — which is exactly what a quiet game looks like — so the timestamp froze at the first write, the row crossed the freshness window, and the model correctly reported a stale row as offline. Verified against the live database: two hours of refreshes, `updated_at` still the boot timestamp. No test in this repo could see it. The model takes its clock as an argument, and nothing in a suite runs the same UPDATE twice against a real database. It is only visible as a page that was right when you looked at it and wrong an hour later. The writer now sets `updated_at = CURRENT_TIMESTAMP` explicitly and the column drops the clause that was not doing what it looked like it was doing; both carry the reasoning. Re-verified end to end: the timestamp advances every interval and the API reports fresh. Falling out of the fix, the schema fragment gained the rule the reader hits next: **changing a table is an ALTER, never an edit to its CREATE** — `CREATE TABLE IF NOT EXISTS` does nothing when the table exists, so an edited column definition takes effect on a fresh install and on no existing one, which is the worst possible split because your development database is usually the fresh one. ## Verified - 29 server tests, 18 client tests, 10 kit-script tests; `check:imports`, `check:externals`, `check:swagger` and `checkCoreApi` all green, run in CI's own order from a clean `npm ci`. - Browser smoke (MODULE_API.md §7.7) against a real core built from the pinned ref: module `started`, published on `/api/v1/public/modules`, chunk served `no-cache` with the right MIME from the entry's directory while `module.json` and the server source 404, script tag injected after core's bundle, the page rendering inside core's own chrome, the nav row interleaved into the public header between Wiki and About, SPA navigation into it from another page, the module's path and schema and tag merged into `/api/docs.json`, and `[examplegame] registered against core API 1.4.0` in the console with no CSP report and no React error.
