Two downloads under the token — the FHIR document Bundle and the clinical PDF —
behind the same unlock cookie the document route enforces, serving exactly the
link's frozen selection. That is what the removed FHIR toggle promised, in the
form a practice actually uses: open the link, unlock it, save the file. No new
credential type, no new scope, no mint path that does not exist.
The gate is the document route's, step for step: the same live check, the same
token-scoped cookie, the same blunt 404 for every miss class so a probe cannot
tell "no such link" from "revoked" from "documents-only". It differs in one
number, because generating a bundle is far more expensive than serving a stored
blob and must not share a budget with it. Each download writes its own audit
row. The scope cannot exceed the page's: both resolve the same frozen leaf list
through the same resolver, and the insurance leaf is refused at create, so the
insurance number cannot reach this path at all.
The MCP doctor-visit summary stops claiming presence it cannot support. An
account whose owner never saved a report selection resolves to the empty one on
that surface, and an empty scope produces an empty payload — which now reads as
{ present: false, reason }, the same sentinel the other reads use, instead of a
record with every section quietly missing.
Mutation-checked: removing the unlock check, the rate limit, the documents-only
guard or the audit row reddens its own case; pointing the bucket at the document
route's key reddens the bucket assertion; making presence unconditional reddens
the absence case.
The saved profile's shape moves out of the module that reads the row. The panel
is a client component and parses the blob from the /me payload; importing the
reader dragged the database client into the browser bundle, which typecheck and
the unit suite both pass and only `next build` catches.
The report resolved an absent key to "included". A caller that sent no
sections object, or an empty group inside one, received the full record at
server-chosen defaults: roughly fifty metrics plus the medication list, labs,
allergies and family history. The web panel sent every key explicitly so it
looked fine from the browser, but the share link, the FHIR REST face, the MCP
doctor-visit resource and the cycle-only export card all went through paths
where absence meant yes. No arrangement of booleans fixes a default that means
yes, so the shape goes.
A selection is now an inclusion list of leaf ids. A leaf is the smallest thing
that can be released or withheld: every measurement type, and thirteen
structured sections — identity, insurer, the glucose panel, labs, the drug
list, the administration ledger, adherence, the GLP-1 block, allergies,
illness episodes, family history, mood, cycle. Membership is inclusion,
absence is exclusion, and there is no defaults constant anywhere to drift.
Three locks keep a metric added later off a report chosen earlier. A stored
selection is a list of what was chosen, so a leaf that did not exist then is
not in it. The catalogue is keyed over the measurement enum, so adding a
member without deciding its group fails typecheck in the same commit. And the
aggregator's filter inverts: a type the catalogue does not know is excluded and
annotated, where it used to be passed through.
The aggregator's third parameter is now required and brand-typed, which turned
the three surfaces that had no scope at all into compile errors. Each one had
to name a source, and each now replays the owner's saved selection — the same
object reviewed in Settings. An account that never saved one gets nothing
there rather than a guess.
Identity and insurance become selectable, and a share link refuses the
insurance leaf outright. The share view never decrypted the number; that is
structural now instead of incidental. The KVNR is not even read unless the
leaf was chosen.
Two surfaces gain a record they always implied. A share link serves its frozen
selection as a FHIR bundle and as the PDF, behind the same unlock cookie the
document route uses, with its own rate bucket, its own audit row and the same
blunt 404 for every miss. That is what the removed FHIR toggle promised, in
the form a practice actually uses.
The AI summary leaves the report. Its text came from the cached briefing with
no relation to the selection, so its scope could not be proven, and prose whose
scope cannot be proven has no place on a document whose whole point is a proven
scope.
The PDF table stops being a nine-type whitelist. It prints every selected leaf
that has data, sub-headed by group, in the same order the panel shows — so
selecting resting heart rate no longer means seeing it in the bundle and not in
the PDF. The clinician view is grouped the same way and reads real labels
instead of "Phq9 score".
Migration 0273 adds the saved-selection column, drops the orphaned prefs column
and the two retired share-link scope columns, and revokes every live record
share link minted before this model. Their frozen scope was "everything except
mood and cycle", which is a scope nobody chose; narrowing it would still be a
scope nobody chose. Documents-only shares are untouched. The sharing list shows
each closed link in a pick-again state with its label, window and expiry kept.
The retired allowFhirApi and resourceTypes stay on the create and list
responses as the constant false and empty list. The request refuses them. They
come off the response once the native client confirms it does not decode them.
Six files are split at seams this change already touched: the aggregator into
its gate, its dense-bucket query, its series, its glucose panel, its medication
ledger and its clinical records; the export route's three emitters into their
own module; the clinician view into its sections, its document list and its
downloads.
Two layers, because the defect had two halves and each needs its own kind of
proof.
The structural guard walks the panel's control shape, folds every control
through the wire schema and the resolver the route uses, and fails when
flipping one changes nothing in the resolved selection. It also checks the
panel renders a row for every control it declares, and that every resolved
flag is read downstream, either by gating measurement types or by name in the
aggregator. That is the link nobody had written: the dead switches were dead
for several releases and no test connected "the panel renders this" to "the
export honours this".
The behavioural half runs the real export route and reads what comes out. The
previously-dead measurement switches are asserted against the FHIR bundle and
the PDF table, with a positive control beside each exclusion so nothing passes
on an empty fixture. The screening totals are asserted absent for a caller
that names other sections and for a caller that sends no sections at all, then
present when asked for by name. Allergies and family history are asserted
absent from the bundle and never read from the database, and the package case
opens the zip and checks the bundle inside it agrees with the PDF beside it.
Mutation-checked: reverting the allergy gate, the medication-list gate, the
screener entries or the measurement entries turns the matching cases red and
leaves the rest green; removing a control's fold entry or its aggregator entry
turns the guard red with the control named.
The remaining changes update fixtures the new shapes touch: prefs objects now
resolve the added flags from the defaults, and the share-link fixtures drop
the retired FHIR scope, with a case pinning that the create route now refuses
those keys instead of ignoring them.
Client-rendered times fell back to the hardcoded display zone
(Europe/Berlin) because neither useFormatters() nor the legacy format.ts
helpers ever received users.timezone. A third localStorage mirror
(timezone-mirror.ts, following the time-format/date-format pattern)
carries the validated profile zone from /api/auth/me into both read
paths; the fallback chain is strictly profile → Europe/Berlin — never
the browser zone, so screen, PDF, and export cannot disagree.
makeFormatters validates its zone before Intl (a poison value falls back
instead of throwing inside every render).
Same pass, per the two-document audit: formatUpdatedLabel boundary and
clock now resolve one zone in every state (the undefined-tz browser hole
is closed); @db.Date calendar fields render UTC-pinned so profiles west
of UTC cannot shift a day; dose-history day headings and GLP-1 weekday
labels derive from the display zone; chart day/month labels are
encoding-derived and UTC-pinned (bucket math untouched, byte-identical
for Berlin profiles); the clinician share view renders in the patient's
timezone instead of the container's; Playwright pins Europe/Berlin.
Server day-key semantics, streak anchoring, insight cache keys, and
verbatim wall-clock strings are untouched by construction and pinned by
the new Auckland/New_York/Manila + DST test matrix.
Dashboard layout changes take effect immediately: the save now evicts the
locale-keyed home-screen snapshot it previously missed, so a re-ordered or
toggled tile set no longer reverts to the prior selection for the SWR window.
A share link built with a narrowed report-section selection now serves exactly
that selection. The stored selection is the grouped export shape; the shared
view read it through the flat parser, which dropped every grouped toggle and
fell back to the full defaults — an over-share against the owner's choice. The
view now folds the grouped shape down faithfully. Documents-only shares were
never affected.
Hardening: the shared-document download path now sanitises the filename
identically to the owner download path, and thumbnail generation re-checks the
pixel ceiling after decode so a malformed image that slips past the header
sniff still cannot exhaust the worker.
Sharing a single document from the vault minted a full-record share: the
create form always defaulted `resourceTypes` to ["Patient","Observation"]
and never signalled a documents-only intent, so the served /c/<token> view
aggregated the whole doctor report — every vital, lab, medication and
wellness figure — alongside the attached file. An empty section blob was
indistinguishable from "defaults", so the report always resolved to the
full record.
Introduce an explicit documents-only share:
- add a `documentOnly` flag to the create payload; when set the server
forces an empty report scope (all-off sections, no FHIR resource types,
FHIR API off) and requires at least one document, so a document link can
never widen into a record — whatever the body sends.
- gate the clinician-view aggregation on an enabled section: a share with
no section on never calls the report aggregator, so no health metric
leaves the database. The recipient sees only the attached document(s).
- the document detail Share action opens the create form in documents-only
mode: hide the FHIR toggle, the FHIR resource-type checkboxes and the
history-range selector, keep the picker/label/expiry/passphrase, and
always carry the launched document into the created link.
- Settings sharing keeps the full record-share form unchanged.
Extract the create-payload builder as a pure function and cover the scope
contract, the empty-scope data load, and the served-view metric-free
guarantee with tests; refresh the share e2e and regenerate the OpenAPI
contract.
P3-1-T4. Cover token confinement to the frozen set, EXIF strip on egress,
Class A inline vs Class B attachment posture, HTML/SVG never inline, foreign /
soft-deleted / owner-mismatch id → 404, revocation-and-passphrase-before-
decrypt, per-link rate limit, and fail-closed decrypt.
P3-1-T2/T4/T5. Extend createShareLinkSchema with an optional, bounded
documentIds set; validate each id as the caller's own live document and create
the membership rows in the same transaction (frozen write-once). Summary DTOs
gain documentCount (never ids, never bytes).
Add the public share-scoped serve route /c/<token>/d/<id>: token-resolved
(never requireAuth), passphrase-gated via the token-scoped unlock cookie,
revocation/expiry re-checked before any decrypt, confined to the link's frozen
document set (foreign/deleted id → flat 404), fail-closed decrypt, identical
serving-class posture as the owner route (inline Class A / attachment Class B,
nosniff, no-store), EXIF-stripped for raster images on egress, per-link rate
limit.
Carve the serve path out of the proxy's blanket DENY posture with the same
document CSP as the owner route (default-src 'none'; frame-ancestors 'self'),
anchored to exactly two dynamic segments so no lookalike over-matches.
A render failure on `/c/<token>` previously fell through to the full-app
error screen, which carries app chrome the public share view never wants.
Add a route-scoped, chrome-free error boundary that shows a localised,
stack-free message and a single retry. Add the matching copy across all
six locales.
The passphrase gate is a client component, but the page passed it a `t`
translator function. A function cannot cross the server→client boundary,
so a fresh (passphrase-protected) link threw a generic server-components
render error instead of painting the unlock form. Pre-resolve the gate
copy on the server into a plain, serializable `strings` object and pass
that instead. Locale resolution stays server-authoritative.
The page test mocked the gate away and only checked the token prop, so
the regression slipped through. Tighten it to assert the gate receives a
serializable contract: no prop value is a function, and the copy arrives
as a pre-resolved plain string object.
One-shot prettier pass so the new format:check gate starts from a clean
baseline. Formatting only — no behaviour change. Generator-owned and
vendored artifacts stay untouched via .prettierignore.
A protected share link no longer renders the record until the passphrase
is verified. The public page checks the gate state first (without bumping
access counters), and for a link with a passphrase hash it serves a gate
island unless a valid, token-scoped unlock cookie is present. A legacy
link with a null passphrase hash renders exactly as before.
The unlock route verifies the submitted passphrase with a constant-time
compare against the stored hash, is rate-limited by share-unlock token
and IP before any compare, and on success sets a short-lived (30 min)
httpOnly, SameSite=Strict, Secure cookie scoped to that one token's view
path. Every failure class answers one blunt 401; no-store and the flat
404 for unknown links are preserved. The gate island auto-submits the
#k= fragment (scrubbing it from history first) or prompts for input.
A standalone read-only RSC that resolves the path token through the share-token
resolver and renders an owner-scoped clinical summary: provenance header,
clinical vitals and labs, medications with adherence, and a fenced muted card
for the descriptive wellness scores carrying the not-a-clinical-assessment,
not-a-diagnosis disclaimer. KVNR is default off. No app chrome, no coach, no AI,
no session, no markdown — every value renders as escaped text. force-dynamic and
noindex; the page returns a flat 404 for any null resolve.
The route joins the proxy public-path allowlist and the AuthShell standalone
list so it reaches the page bare without a sign-in redirect. New clinicianView
strings land in all six locales.
