/**
* Structural guard: no lab value reaches a model while the labs module is off.
*
* ## The failure this freezes
*
* The Coach snapshot carried a labs block "intentionally not module-gated", a
* decision from before Labs could be switched off. Once it could, the Coach
* prompt, its `get_labs` tool, the daily briefing, the biomarker status note,
* the reaction line to a new panel and the MCP lab-trend prompt all kept
* reading lab values for the model after the owner had turned the module
* off, while the snapshot's own prelude promised that "the model never sees
* a disabled domain". Each read was a separate module with its own
* `prisma.labResult` query, and nothing tied them to the switch.
*
* ## What it proves and what it does not
*
* Every module under the paths that build model input (`src/lib/ai`,
* `src/lib/insights`, `src/lib/jobs`, `src/lib/mcp`) that reads the lab
* table either asks the labs module itself (`isModuleEnabled(…, "labs")`,
* the `correlation:LAB_DRAWS` surface, or the MCP `whenModuleOn` wrapper) or
* is listed below with the reason its read cannot reach a prompt. A new
* reader fails here until it does one or the other. The data routes are not
* in scope: a module decides what a model is given, not what the owner can
* read (`CLAUDE.md`, "An AI capability gates model work").
*
* It is grep-shaped: it sees a read, not where the rows go, and a reader in
* another directory is outside it. The behaviour is pinned per path by the
* module-off cases in the suites of the readers themselves.

* Replay protection (v1.16.4). A captured webhook request carries a
* static shared secret, so without a freshness check it can be replayed
* indefinitely — re-paging admins with stale failure alerts and
* polluting the audit log with forged deploy outcomes.
* Freshness and signature.
*
* The sender attaches `X-Deploy-Webhook-Timestamp` (unix seconds or
* ISO-8601). Requests whose timestamp falls outside a ±5-minute window
* are rejected. Two modes:
* The secret header alone cannot stop a replay: whoever holds a captured
* request holds the secret it carries, and can send a fresh request of any
* content. A timestamp beside it changed nothing, because the timestamp was
* covered by nothing and could be rewritten with the rest. Earlier versions
* called it replay protection; it was a staleness hint.
*
* - Default (tolerant): a request WITHOUT the header passes — Coolify's
* stock notification sender does not attach one, and breaking the
* live integration would cost more than the residual replay window.
* A header that IS present but stale/invalid is always rejected, so
* a replayed capture of a timestamped request never lands.
* - `DEPLOY_WEBHOOK_REQUIRE_TIMESTAMP=true`: the header becomes
* mandatory. For operators whose sender (or reverse proxy) can
* attach the timestamp; closes the replay window completely.
* A sender that can compute a signature authenticates without sending the
* secret at all: `X-Deploy-Webhook-Signature: sha256=<hex>` is the
* HMAC-SHA256, under `DEPLOY_WEBHOOK_SECRET`, of the timestamp header's
* value, a dot, and the raw body, and the timestamp must lie within five
* minutes. A capture of such a request is useless after the window and
* reveals no secret.
*
* - Default: a signed request is verified as above; an unsigned one
* authenticates with the secret header, as Coolify's stock sender does,
* and a timestamp it carries must still be fresh.
* - `DEPLOY_WEBHOOK_REQUIRE_TIMESTAMP=true`: only a signed request is
* accepted. The name predates the signature; requiring a timestamp
* without one would not make a replay any harder.
*
* See docs/ops/deploy.md ("Deploy-status webhook") for the operator
* guidance.

* gigabytes while decoding it, and a content stream can keep the parser busy
* for minutes. Both used to happen inside the web process, where they took
* every user's requests down with them. Every caller now goes through
* `./pdf-isolation.ts`, which runs this module in a child process
* (`./pdf-child.mjs`) under a memory ceiling and a time limit; a document that
* crosses either one ends the child, not the server. The suites still import
* it directly to test the reading and rendering themselves.
*
* It is plain JavaScript because the child runs it with plain Node, from the
* checkout and from the standalone image alike; `@ts-check` keeps the
* compiler on it all the same. It imports nothing from the app, and it logs
* nothing: the caller in the server says what happened.
*

* second copy out.

/**
* Runs pdf.js in a child process with a memory ceiling and a time limit.
*
* A PDF's cost is set by whoever wrote it. A 400 KB file can declare an image
* of twenty thousand pixels square, and pdf.js allocated about 7 GB decoding
* it; a content stream can keep the parser busy for minutes. Inside the
* server either one took the web process, every user's requests and the
* background jobs down with it, and the job queue then retried the same
* document after the restart. pdf.js' own `maxImageSize` stops the first
* shape (see `./pdf-engine.mjs`), but an image mask, a font program or a
* shading can still allocate in proportion to what the file declares. So the
* reading itself happens in `./pdf-child.mjs`, one process per document:
*
* - the child's V8 heap is capped with `--max-old-space-size`;
* - its resident memory, which also counts the image buffers outside the
* heap, is sampled from here and the child is killed past the ceiling;
* - on Linux the child marks itself as the first thing the kernel's
* out-of-memory killer takes, for an allocation faster than the sampling;
* - it is killed when the time limit runs out;
* - it starts with an almost empty environment, so it holds no key, token
* or database address;
* - one runs at a time (`MAX_PARALLEL_CHILDREN`), so a burst of uploads
* cannot multiply the ceiling.
*
* A document that crosses a bound fails with `limit` and is not something a
* retry will fix; callers record it as a final failure.
*
* This module logs nothing and imports nothing from the app, so the
* end-to-end suite can read report text through `./pdfjs.ts` as well.

* Under Node, pdf.js does not start a worker thread: it loads its worker code

* copy of pdf.js opens a document first owns that global until the process
* exits, and any other copy then refuses every document with "The API version
* … does not match the Worker version …". The server used to load two copies,
* one for the local text read and one for rasterizing, so whichever ran first
* broke the other until a restart (#1277). Both paths now open documents
* here, through the app's own `pdfjs-dist`, with the same options;
* `src/__tests__/single-pdfjs-guard.test.ts` keeps a second copy out.
*
* pdf.js is loaded lazily with a runtime `import()`: its module top level
* reads the browser-only `DOMMatrix` global, so a static import would make the
* server chunk evaluate it at instantiation and throw `DOMMatrix is not
* defined`, taking down every route and worker sharing the chunk. The import
* resolves once and is module-cached after that. The type imports below are
* erased at build, so they load nothing; they let the compiler check every
* call here against pdf.js' own API.
* Reading a PDF's text layer, the way the server does it: in a child process
* under a memory ceiling and a time limit (`./pdf-isolation.ts`), through the
* one pdf.js loader (`./pdf-engine.mjs`). Rendering goes the same way from
* `./rasterize-pdf.ts`.

* - `Sec-Fetch-Site: same-origin` or `none` passes; `same-site` and
* `cross-site` are refused.
* - Without `Sec-Fetch-Site`, an `Origin` passes only when its host is the

* proxy) or the configured `APP_URL`. A page cannot set either header
