Marc-André Bombeck d99456138b test: classify the Insights presence read in the route inventories
The presence read is data, never AI, and spans every module: each flag
whose page a switched-off module hides answers false without reading
the rows. Both inventories now say so.

/**
* v1.18.0 — module API route gate inventory.
*
* The v1.18.0 module retrofit can hide a toggleable module across the
* nav, dashboard tiles, Insights pills, reminder jobs, doctor-report
* sections, and the AI surfaces. The ONE server-side enforcement point
* is `@/lib/modules/gate` — `requireModuleEnabled(userId, key)` in API
* routes, `isModuleEnabled` / `resolveModuleMap` in builders + jobs +
* components. Without a discovery test, a future contributor who lands a
* new per-domain route for a toggleable module (a new mood-analysis read,
* a new sleep view, a new glucose panel) would have to remember the gate
* by hand. A silent miss leaks the surface over a Bearer token even when
* the account — or the operator — turned the module off.
*
* This test walks every per-domain route tree that serves a TOGGLEABLE
* module and pins each `route.ts` into exactly one of these buckets:
*
* 1. MODULE-GATED — the file calls `requireModuleEnabled(...)` for the
* right key (mood / sleep / glucose / workouts / recovery / labs /
* achievements). This is the direct gate.
*
* 2. DELEGATED — the module's enabled-state is owned elsewhere and the
* route gates on that single source of truth instead of re-deriving
* it (no double source of truth, mirroring the registry's
* `delegatesTo`):
* - cycle → `requireCycleEnabled(...)` (the cycle gate the
* `cycle` ModuleKey delegates to).
* - an AI capability → `requireAiCapability(key)` /
* `getAiCapability(key)`. A capability resolves its owning
* modules and the AI opt-out (the `coach` module and
* `disableCoach` for the Coach, the `insights` module for
* every other capability), so an AI route that names one is
* gated on those modules. Covered in depth by
* `ai-capability-route-inventory.test.ts`. The `insights`
* module is the AI analysis opt-out and gates only AI parts;
* the data routes that happen to live under
* `/api/insights` are EXEMPT below.
*
* 3. EXEMPT — an explicit, COMMENTED allowlist of routes that serve a
* toggleable domain but are deliberately NOT gated, each with the
* reason at the entry. The two reasons in play:
* - DATA LAYER: raw CRUD over the domain's own rows. Writing or
* reading a disabled module's data is harmless — the module gate
* governs whether the domain SURFACES (nav, tiles, analysis,
* reports), not whether the row store accepts writes. Disabling
* a module must not wedge an importer / sync / the user's ability
* to clean up data, and re-enabling must find the data intact.
* - INFRA / UI-ONLY: settings, availability probes, and the static
* FHIR CapabilityStatement carry no module data.
*
* Anything that doesn't fit one of the three buckets is an orphan and
* fails the test BY NAME so the fix is one search-and-add: gate the route
* or move it onto the EXEMPT allowlist with a documented reason.
*
* WHAT THIS TEST DOES NOT PROVE, AND WHO PROVES IT
* -----------------------------------------------
* This file is a DISCOVERY test: it proves no route escapes classification.
* It cannot prove a gate actually refuses, because it only reads source text.
*
* That distinction used to be blurred. A fourth "BUILDER-GATED" bucket
* accepted the mere MENTION of an aggregator's name (`loadFhirContext`,
* `collectDoctorReportData`) as proof that the route was gated. It was not
* proof of anything: `loadFhirContext` filtered per-domain modules but never
* evaluated `doctorReport`, so all five `/api/fhir/*` data routes sat in a
* green bucket while serving the whole record — including the decrypted
* insurance number — to an account that had the doctor-report module off.
* The bucket is gone. A route is now only counted as gated when it CALLS a
* gate, and `REQUIRED_TREE_MODULE` below pins which key it must name.
*
* The behaviour itself — a disabled module actually producing a 403 or an
* omission — is proven by the per-surface tests listed in
* `BEHAVIOURAL_GATE_TESTS`. This test asserts those files still exist, so
* deleting the behavioural coverage fails here with a pointer to what was
* lost rather than silently leaving only a text-match behind.
*
* WHICH TREES GET WALKED, AND WHY THAT IS NOT A HAND-WRITTEN LIST ANY MORE
* -----------------------------------------------------------------------
* A discovery test is only worth what its discovery covers, and this one used
* to enumerate its trees in a flat array that grew when somebody remembered to
* grow it. It had stopped: `coach`, `environment`, `mentalHealth`,
* `inboundDocuments` and `mcp` each shipped an API tree that this file never
* looked at. No leak came of it — every route in the first four gates — but
* that was the authors' care and not this test's, and a green run was saying
* something narrower than it appeared to say.
*
* The trees are now declared per module key as an exhaustive
* `Record<ModuleKey, …>`, so the REGISTRY drives coverage: a new key does not
* compile without an entry, and an API directory named after a key is
* discovered from the filesystem and must be declared for it. A tree at a
* non-obvious address (`achievements` → `/api/gamification`) still has to be
* named by hand — that is the residual gap, and it is the reason the
* declaration carries a comment per key rather than a bare path.
*/
/**
* The per-domain API route trees each toggleable module owns, keyed by the
* registry key.
*
* Declared as an exhaustive `Record<ModuleKey, …>` so the REGISTRY drives
* coverage rather than anybody's memory: adding a key to `MODULE_KEYS` without
* deciding which API tree it owns does not compile, and the two tests below
* catch the same omission at runtime — one asserting every registry key is
* declared, one asserting that an API directory NAMED after a module key is
* declared for that key.
*
* The hand-written array this replaced could only grow when a contributor
* remembered to grow it, and it had stopped growing: `coach`, `environment`,
* `mentalHealth`, `inboundDocuments` and `mcp` all shipped an API tree that
* this inventory never walked. Every route in the first four turned out to be
* gated, so nothing leaked — but that was the authors' care, not this file's
* doing, and the next tree would have been just as invisible.
*
* An empty array is a claim, not a gap: the module owns no API tree of its
* own, and the entry says where its data actually lives.
*
* A domain owned entirely by one builder (doctor-report / FHIR) or one
* delegated gate (cycle) is still walked, so a NEW route in the tree must
* justify itself.
