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.
