A share link created to carry only documents now records an explicit,
frozen document_only flag, and the shared view gates on that flag directly
instead of inferring documents-only from "are all report sections off?".
The inference would have re-opened an existing documents-only link the day
a new report section was added — the link's frozen settings never mention
the new section, so it would default on and begin serving that data. The
flag closes that path; the derived check stays only as the fallback for
links created before the column.
Migration 0237 adds the column and freezes it on for every existing link
whose sections are entirely off (checked at any nesting depth), leaving
full-record shares untouched.
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-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.
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.
Every new share link now carries a high-entropy passphrase (80-bit,
Crockford-base32, grouped XXXX-XXXX-XXXX-XXXX). The create response
returns the raw passphrase, the share URL, and a QR deep link EXACTLY
ONCE alongside the token; the server stores only the passphrase's HMAC
hash (the same key as the token hash). The QR deep link carries the
passphrase in the URL fragment (#k=) so it never reaches a server log,
referrer, or access record.
Add the passphrase generator, normaliser, and constant-time verifier;
the short-lived token-scoped unlock-cookie mint/verify; a gate-state
resolver that reports live + passphrase status without bumping access
counters; and the unlock request schema.
Authenticated owner routes to create, list, and revoke a ClinicianShareLink.
Create mints an hls_ token (192-bit), stores only its HMAC hash, and returns
the raw token exactly once; the scope columns (window, sections, FHIR resource
types, API toggle) are frozen write-once. expiresAt is required and capped at
SHARE_LINK_MAX_DAYS (90). Revoke sets revokedAt and seals a cross-user id as
404. userId is narrowed from auth; rate-limited; strict Zod rejects unknown
keys. This is the owner lifecycle only — the public resolver/view is separate.
