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](../../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](agent-guidance-migration.md) 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.
