First step of the performance-journeys ratchet (plan thread: J1 `launch`, counter `renderer.initialBytes`).
- `tools/performance/measure-initial-bytes.mjs` reads the built `dist/apps/web/index.html` and sums `index.html` plus every same-origin `<script src>`, `<link rel="stylesheet">` and `<link rel="modulepreload">` it references. Manifest, icons, external URLs and lazy chunks are not counted. A referenced file missing from the build fails the measurement instead of counting as zero bytes.
- `--json` prints the breakdown; `--summary <file>` writes the `journeys.<journey>.counters` shape a ratchet checker will consume (next PR).
- New Nx project `performance-tools` (test + lint targets), Tier B in `tools/coverage/coverage-policy.json`, root scripts `perf:initial-bytes` and `perf:tools:test`.
- New contract `docs/architecture/performance-journeys.md`, linked from the validation map, the agent context map and the README.
- **Review follow-ups:** resources are deduplicated by request URL (query kept, fragment dropped); `index.html` is parsed with parse5 (already a repository dependency, scripting enabled), so comments, bogus comments, raw-text bodies (script/style/noscript/title/textarea), inert `<template>` contents and character references in attributes all follow the HTML5 algorithm instead of a hand-written scanner; the review's edge cases stay as regression tests; docs show the `pnpm --silent` form for JSON output and explain how the counter relates to Angular's rounded "Initial total".
- **Found while measuring:** the environment files and the playback diagnostic panel imported the whole `package.json` (`import packageJson from '@package'`), which esbuild cannot tree-shake, so `main.js` carried the complete file and the counter moved with every script or dependency edit. They now import `{ version }` only (eb662c485): `main.js` shrinks by **11,539 bytes** and the counter no longer depends on `package.json`. Jest's ESM loader exposes JSON only as a default export, so the two web Jest configs map `@package` to a stub that serves the real file's fields as named exports. Release note: `.changes/web-version-only-from-package-json.md` (`type: perf`).
Production build after this PR measures **2,739,508 bytes** (11 files + `index.html`); Angular's "Initial total" is this minus `index.html` and `assets/app-config.js`. The baseline file and the CI check land in the follow-up PRs; C1 (lazy Angular date locales) then lowers it.

Agent context map
Read the row for your task before editing. For a cross-domain change, read each affected contract. This is navigation, not a request to load every linked file. Common constraints remain in AGENTS.md; Claude imports it. Repository skill frontmatter defines triggers. If your client does not discover a listed skill automatically, read its SKILL.md directly. Optional global tools are not prerequisites for reading repository contracts.

Maintenance rules
Keep unique behavior contracts in the authoritative document, procedures in a
skill or development guide, and universal constraints in AGENTS.md. Update this
map when ownership or a canonical destination changes. Preserve release skill
mirrors; do not create extra copies of other contracts for individual agents.
Use normal Markdown links for document destinations so pnpm run agents:validate
can check them. Do not add root imports for the linked documents.
The migration ledger explains how the original root instructions were accounted for. It is historical audit evidence, not another source of current runtime policy or required task context.
