+- The runtime stage copies the built `js/` and `css/` directories (not single

+---
+
+`deno bundle` was replaced by `vp build` in **Vite app mode** (not
+`build.lib`). Behavior must not change, so the output keeps the file names and
+locations the backend serves and the HTML references.
+
+Typical shape for the Rust-backed frontends (home, eximium, stockvibe,
+memona-home), where `frontend/` builds into `backend/static`:
+
+```ts
+build: {
+  outDir: "../backend/static",
+  emptyOutDir: false, // the folder holds committed files (index.html, ...)
+  rollupOptions: {
+    input: { bundle: "src/index.ts" },
+    output: { entryFileNames: "js/[name].js" }, // -> js/bundle.js
+  },
+},
+```
+
+- **Fixed names, no hashes:** set `entryFileNames` (and `assetFileNames`
+  where assets are emitted) explicitly. Vite's hashed defaults would 404,
+  since Rust and the templates request `js/bundle.js` and `css/theme.css`.
+- **`emptyOutDir: false` whenever `outDir` is outside the Vite root or holds
+  committed files.** Never let it default to true there: it would wipe them.
+- Output stays gitignored, so `.gitignore`, `.containerignore`, and the Rust
+  side need no edits; home's startup check for `js/bundle.js` and
+  `css/theme.css` keeps passing.
+- **CSS is never imported from TS** (no `import "./theme.css"`); the HTML
+  links the stylesheet. How the CSS file is produced is per repo; read the
+  repo's `vite.config.ts` before changing it.
+- Copy whole `js/` and `css/` directories in Containerfiles, not single files,
+  so code-split chunks ship too ([[app-containers-and-ci]]).
+- Where a repo serves an `index.html` entry (brain's dashboard), use plain app
+  mode with `index.html` as input, `base` set to the mount path, and `outDir:
+  "dist"` with the default `emptyOutDir`.
+- `vp dev` must work too, and the decorators plugin must cover build, dev, and
+  test ([[decorators-standard-accessor]]).
+
+Check the repo's own migration PR for its final values before editing; these
+are the conventions it followed, not a config to paste.

+
+1. The custom Deno lint plugins were ported to npm first, as

+   `cunarist/eslint-plugin-explicit-types` is the template every other repo
+   copies (config shape, `scripts/project-lint.ts`, AGENTS.md, notes).
+2. Then `commons/bot-agents` (six repos use it as an action), then the apps:
+   home, eximium, stockvibe, brain, memona, memona-home.
+3. deno-practice, interview-practice, web-landing, and vemium were left out

+- Only three config files and only `.ts`: [[toolchain-node-vite-plus]],

+</svg>`;
+```
+
+```ts
+// usage
+import { lockIcon } from "#icons";
+render() { return html`<span class="icon">${lockIcon}</span>`; }
+```
+
+- One icon per file, camelCase name with an `Icon` suffix, a doc comment
+  saying what it depicts, exported through `src/icons/index.ts`.
+- Use `fill="currentColor"` so CSS controls the colour.
+- Keep a third-party licence comment that the SVG source carries (Font
+  Awesome Free's `<!--! ... -->` notice) inside the template.

+Awesome `.svg` files as text in `icons.ts`:

+```ts
+import lock from "@fortawesome/fontawesome-free/svgs/solid/lock.svg" with { type: "text" }; // no
+```
+
+That breaks [[ts-only-files-and-imports]] (non-`.ts` import plus import
+attributes) and was converted to memona's style during the frontend
+migration. Before writing new icon code in any repo, read how that repo (or
+memona) already declares icons and match it.

-  No alias to a single file, a deeper folder, or anything outside `src/`.
-  Here the one alias is `"#testing": "./src/testing/index.ts"`.
-- Code outside `src/` (`scripts/`, `tests/`, `vite.config.ts`) gets no alias
-  of its own and imports its own files by `./` relative paths. It reaches
-  `src/` only through the aliases, since `../` is banned.

+Applies to Lit repos that ran `cunarist/deno-lit-analyzer` under Deno.
+
+lit-analyzer is built on TypeScript's JavaScript compiler API and is run
+against TypeScript 6 (the open question was whether it works with TS 7 /
+tsgo). The repo installs TS 6 under another name and redirects lit-analyzer
+to it, so the rest of the toolchain is unaffected (decided 2026-10-16):
+
+```jsonc

+"scripts": { "lit-check": "node scripts/lit-check.ts" },
+"devDependencies": { "typescript-6": "npm:typescript@^6", "lit-analyzer": "..." }

+    return next(specifier === "typescript" ? "typescript-6" : specifier, context);
+  },
+});
+// then run lit-analyzer

+
+- Node runs the `.ts` script directly (type stripping), so no build step.

+  spawn the package's bin with `node:child_process`, instead.
+- CI runs `npm run lit-check` as its own step.
+- It is tooling under `scripts/`: no tests; a narrow `overrides` entry for it
+  (e.g. `no-console`) is allowed if truly needed.
+

+Standing convention (2026-10-12), applied to every package:
+
+- **Only CI publishes.** Publishing a GitHub release `vX.Y.Z` triggers
+  `.github/workflows/publish.yml`. Never run `npm publish` locally and never
+  push a bare `v*` tag. Use the `release` skill, and only when the user asked
+  for a release.
+- **The workflow** checks that the tag equals `v` + `package.json` `version`,
+  runs the full CI as a reusable workflow (every Node version in the matrix),
+  then `vp pack` and `npm publish --access public --provenance`. A release
+  marked pre-release publishes under the `next` dist-tag, others `latest`.
+  It runs on Node 24 (npm 11, which trusted publishing needs) with no cache.
+- **Auth is npm trusted publishing** (OIDC, `id-token: write`), which also
+  attaches provenance. npm only allows a trusted publisher on a package that
+  already exists, so the very first release bootstraps with a short-lived
+  token in the `NPM_TOKEN` repo secret (the workflow uses it only when set).
+  Afterwards the user configures the trusted publisher for `publish.yml`,
+  deletes the secret, and sets the package to disallow tokens.
+- **Release notes live only on the GitHub release page**
+  (`--generate-notes`, edited there). There is no `CHANGELOG.md`; never add
+  one.
+- **The version lives in two places in plugin packages:** `package.json` and
+  `meta.version` in `src/index.ts`; `tests/package-meta.test.ts` fails if they
+  differ.
+- **Before 1.0**, a change that breaks users (renamed rule id, a rule that
+  fires on more code, removed behavior) is a minor bump.
+- **Before a release**, pack the package and lint a known-bad and a known-good
+  file from separate consumer projects, once through `vp lint` with
+  `jsPlugins` and once through ESLint 9 with the configs. On the lit plugin
+  this caught two bugs that 313 unit tests missed.
+
+The cunarist lint plugins (explicit-types, import-check, lit) are published

+      `index.ts`; `deno.json` imports → `package.json` `imports` (`#x/*`
+      patterns for trailing-slash mappings); `jsr:`/`npm:` → npm packages.
+
+**Code**
+
+- [ ] Only `.ts` files; no non-`.ts` imports: CSS via `<link>`, JSON and SVG
+      as `.ts` modules, icons in memona's style.
+- [ ] `Deno.*` → `node:*` / `process`. Generated JS written as `.ts`, built,
+      gitignored.
+- [ ] Decorators stay standard with `accessor`; add `scripts/decorators.ts`
+      if the repo has any. Lit repos: `scripts/lit-check.ts` + `npm run
+      lit-check`.
+
+**Lint**
+
+- [ ] `scripts/project-lint.ts` copied; old local Deno lint rules ported into
+      it; parity mapping for every former rule; `id-match`; no disable
+      comments; no source `overrides`; refactor size-rule hits.
+
+**Tests**
+
+- [ ] `Deno.test` → Vitest (codemod, then finish TODOs); unit tests next to
+      code, integration in `tests/`; no case dropped.
+
+**Build, ship, CI**
+
+- [ ] `vp build` in app mode with the same output paths, or `vp pack` for
+      packages. Containerfile node stage on `node:24-alpine`. CI with
+      `setup-vp`: `vp check`, build, `vp test` (+ lit-check). Packages:
+      release-triggered `publish.yml`.
+- [ ] `AGENTS.md` with the damem header, `.agents/` notes from the damem kit,
+      README updated (Node.js 22+, no Deno instructions). `damem doctor`
+      clean.
+
+**Finish**
+
+- [ ] `vp check`, `vp test`, build all pass locally; the app runs.
+- [ ] Commit in plain imperative sentences; open the PR (summary, changes,
+      parity mapping, deviations/risks, "CI fails until @cunarist/eslint-plugin-*
+      are published" if relevant, verification, footer line).
+- [ ] Run `review-cycle`. Never merge, publish, or archive.
