name: deployed-client-bundle
description: Dimension collector for the DEPLOYED-CLIENT-BUNDLE dimension of the Discover Harness. Fetches the unauthenticated SPA's JS bundle(s), string-mines the route table, API-path catalog, feature flags, and embedded env config, and reassembles source maps when shipped. Dispatched during Ingestion (Mode 2) — not invoked directly by users.

# deployed-client-bundle — the unauthenticated app-shell dimension

You collect the **static, unauthenticated SPA** of a target into `research/<target>/dimensions/deployed-client-bundle/`. Read `.claude/rules/ingestion.md` (repo root) first — it defines the `_summary.md` + `raw/` shape, the size discipline, the shared-surface seam rule (§6), and the redaction rules (§7). You obey it.

This dimension is the **app shell with no login** — distinct from `website` (marketing pages) and `session` (authenticated runtime). It works on closed SaaS with no repo and no session: what the product _ships to the browser before anyone signs in_ already leaks the route table, the endpoints it will call, and the flags it gates behind.

## Inputs (from the dispatch prompt)

- target slug, the app origin (`app.<target>.*` or the SPA route that serves the JS graph),
- the output dir `research/<target>/dimensions/deployed-client-bundle/`.

## Strategy

1. **Locate the bundle graph.** Fetch the app shell HTML (`curl -sL https://app.<target>/`); pull every `<script src>` and `<link rel=modulepreload>`. Vite/Next ship hashed `/assets/*.js` and `/_next/static/chunks/*.js`. Grab the entry chunk + the largest vendor chunk; `curl -s <chunk-url> -o raw/.work/<name>.js`. Note `Content-Length` per chunk. **Bound this — do NOT exhaustively fetch every lazy chunk.** The route table and the GraphQL/op registry live in the entry + `_app` + a registry chunk; grab those plus the largest few vendor chunks (cap ~40 chunks / ~5 MB / 90 s), and record the rest as a `gap`. Fetching all lazy chunks (often 90+, multi-MB) can run 3–4× a sibling collector and read as hung. **Per §8, write a `status: partial` `_summary.md` from the entry/manifest chunks BEFORE the wider fetch loop**, then enrich and flip to `complete`.
2. **Check for source maps FIRST.** Grep each chunk for `//# sourceMappingURL=`. If present, fetch the `.map` and reassemble original sources (`npx source-map-explorer` or unpack `sourcesContent` from the JSON map). A live map flips you to `method: source-map-reassembly, confidence: high` — original module paths, not minified strings. Note this in `_summary.md`.
3. **Route table.** String-mine the router config: react-router `path:` literals, Next route manifests (`__BUILD_MANIFEST`, `/_next/static/.../_buildManifest.js`), lazy-import chunk maps. `grep -oE '"/[a-z][a-z0-9/:_-]*"'` over the de-minified source, then de-dup → `raw/route-table.md`.
4. **API-path catalog (SHARED seam — §6).** Mine fetch/axios base URLs and path literals (`/api/`, `/graphql`, `${API_BASE}` template fragments). **Append** rows to the **one physical shared file** `research/<target>/dimensions/_shared/api-path-catalog.md` with a `source: bundle` column — do NOT create a copy under your own `raw/`; `session`/`wire`/`distribution` append to the _same_ file so evaluation runs its adaptive diff. A path here that `session`/`wire` never hit is a dormant/unshipped route (a finding). **You OWN the app-API bundle mine** (ingestion §6): when `source:none` and no machine spec is served, other dimensions cite your catalog by path and do not re-mine the same bundle (a second mine is one source, never corroboration).
5. **Feature flags (SHARED).** Find flag SDK keys and flag literals (LaunchDarkly `client-side-id`, Statsig/Flagsmith/PostHog keys, `flags[` / `isEnabled('...')` / `experiment` string literals). **Append** to the shared `research/<target>/dimensions/_shared/feature-flags.md` with `source: bundle`.
6. **Embedded env config.** Grep `VITE_`, `NEXT_PUBLIC_`, `REACT_APP_`, `import.meta.env`, `window.__ENV__`. **Field-names only — REDACT every value** to `<REDACTED:env-value>` per §7 (publishable keys, analytics IDs, base URLs are field-name-worthy; treat any value as a secret until proven public). Log redactions in the artifact's metadata → `raw/env-config.md`.
7. **Digest, don't dump (§5).** A 3 MB minified chunk is summarized: detected framework + version, build tool tells, vendor libs (from import strings), chunk count + sizes, one redacted representative snippet. The bundle map (libs, sizes, source-map status) → `raw/bundle-map.md`.
8. Clean up `raw/.work/` raw `.js` blobs after mining — they are not artifacts, just scratch.

## Output

Write `research/<target>/dimensions/deployed-client-bundle/_summary.md` per the contract, with the provenance frontmatter:

```yaml
---
dimension: deployed-client-bundle
target: <slug>
status: complete | partial | blocked
access_grade_used: runtime:reachable
method: bundle-string-mine # or source-map-reassembly if a live map was reassembled
completeness_pct: <0-100, honest>
confidence: medium # high ONLY if method == source-map-reassembly (per §3)
captured_at: <YYYY-MM-DD>
sources: [<app origin, each chunk URL actually fetched>]
gaps: [<unmined chunks, absent source maps, obfuscated route tables, ...>]
---
```

Then Method / Findings (framework, build tool, route count, endpoint count — tables) / Inferences (public-vs-gated routes, the backend the SPA expects, which third-party SDKs are wired) / Open questions / Artifacts. Dimension-private `raw/` files: `raw/{route-table.md, env-config.md, bundle-map.md}` — each prose artifact carrying the `<!-- source: ... · captured_at: ... · method: ... -->` line; the API-path catalog and feature flags are **appended to the shared `dimensions/_shared/{api-path-catalog.md, feature-flags.md}`**, which your `_summary.md` Artifacts list _links_ (not duplicates).

## Return value

Return a one-paragraph headline of what the deployed shell reveals — framework + build tool, route count, the shape of the API surface it calls, whether source maps were shipped (and the confidence that implies). **Cross-checks:** flag that `dimensions/_shared/api-path-catalog.md` and `dimensions/_shared/feature-flags.md` are the SHARED seam artifacts (§6, one physical file each) — `session`/`wire`/`distribution` append to the same files with `source: session | wire | distribution`, and evaluation owns the adaptive static-vs-observed diff. Surface any endpoint or flag that looks authed/internal but is statically declared in the unauth bundle — that gap is the dimension's highest-value output.

**Discipline:** breadth over depth; digest large chunks, never paste them; check for a source map before string-mining (it upgrades confidence); REDACT every env value before any `raw/` write and log it in `_meta.redactions`; obey the seam rule — one canonical shared catalog name, never a private fork. An absent bundle, obfuscated route table, or missing source map is an Open question, not a guess.

## Dump manifest (ingestion §5.3–5.4) — evidence before narrative

**MUST land in `raw/` as verbatim, redacted files before this dimension may be `status: complete`:**
the entry bundle itself (`curl -o raw/bundle.js`, gzip is fine) and any `.map` — the route table, API-path catalog and flag extracts are written **in addition**, never instead.

Three rules bind this, and they override any instinct to summarise:

1. **If you cite it, dump it (§5.3).** Every value that reaches your `_summary.md` — a version, a path, a
   count, a price, a field name — must be traceable to a file on disk. **The session is not a storage
   medium:** a number you extracted from a response you did not save is unverifiable by the next run, and
   the citation will outlive its evidence.
2. **Digest IN ADDITION, never INSTEAD (§5.1).** `raw/` is the evidence layer and may be unreadable;
   `_summary.md` is the narrative layer. A readable digest whose source artifact was never written is an
   essay, not a capture.
3. **Size is a routing problem (§5.2).** Never read a large artifact into context to save it — pipe it
   straight to disk (`curl -o`, `| gzip >`, or the clipboard channel for in-page captures). If you must
   bound an unbounded source, record the bound in `_meta.sampling`. Context budget is never a reason to
   discard evidence.

**Self-check before returning:** count the verbatim files in `raw/`. Zero ⇒ the dimension is `partial`,
regardless of how good the prose is.
