An owner can now narrow a grant to the parts of their record they mean to
share, and can offer the third level. Both decisions are made once, on the
invitation, and neither widens afterwards.
The invite schema takes `scope`: absent or null is the entire record, which
is what every stored grant means and what an owner who does not narrow still
gets. An empty array, a key outside the vocabulary and the whole-record
sentinel are each refused with a 422 naming the field; `inviteGrant` refuses
the same three underneath, and its `invalid_scope` now has an HTTP mapping
instead of falling into the generic refusal.
Offering MANAGE asks for a fresh second factor when the account has one. That
gate resolves through the session cookie and has no Bearer fall-through, so a
token caller is refused first with `sharing.invite.manage_browser_only` rather
than being told it is not authenticated by a route that had just
authenticated it. The consequence is deliberate: management of a health
record is offered from a browser.
The account payload gains `sections` and `level` beside `access` and
`canWrite`, resolved server-side and ordered as the consent screen reads.
`access` was `grant.access === "WRITE" ? "write" : "read"`, which would have
published a grant that can delete entries as read-only; it is a total map
now, so the next level cannot ship silent. The capabilities hook carries both
facts and turns neither into an affordance yet — the edit and delete controls
come back in the release where the routes behind them answer.
The consent surface asks two questions in order rather than laying out a
nineteen-cell grid. The level is three radios, narrowest preselected. What
they can open is two radios, the entire record preselected, and only the
narrow branch expands the eight sections with a sentence each. Both honest
limits are stated above the checkboxes, where the decision is being made: a
section shares everything written in it, and the cross-record surfaces do not
appear for a narrowed grant. Documents carries its own warning, cycle appears
only for an owner who tracks it, and Manage collapses the question to the one
line that answers it.
The Manage sentence says the other person can add, change and remove entries,
including ones the owner entered themselves, and says in the same breath what
it does not reach. The acceptance side gets its own responsibility line rather
than the write one wearing a stronger adjective.
Six locales.
A grant has meant one thing since it shipped: the whole record, to read or to
add to. This lays the words for the two shapes the rest of the sharing work
needs — part of a record, and management of one — while changing what no
existing grant does.
`ShareDomain` is a closed set of eight sections in `src/lib/sharing/scope.ts`,
clustered from the delegable read surfaces rather than invented, plus the
distinguished `record` for the routes that read across them. It never converts
to a `ModuleKey` and never imports one: two masks, two questions, no shared
spelling, because the day they share a name is the day somebody makes one
imply the other, and a module the owner enabled is not a section the owner
shared.
`account_grants.scope_json` is NULL on every row that exists, and NULL is the
entire record — the answer those rows were consented as, so no backfill and no
re-consent. A non-NULL value is read through one fail-closed normaliser: a
blob it cannot parse opens nothing, including a section the blob happened to
name. That is the deliberate inverse of the module preference normaliser,
which fails open on purpose; both do the safe thing with a value nobody can
read, and the safe thing differs because one answers an authorization question
and the other a presentation question.
`MANAGE` joins the level enum, ordered above WRITE so a write grant can never
satisfy it, and carries no scope at all: management of part of a record
promises a boundary that cannot survive an edit, so the invite path refuses to
write one.
`requireRecordAuth` takes the section as a second required argument. The
requirement is the lever — a delegable route without a classification does not
typecheck, so the set of classified routes cannot fall behind the set of
delegable ones. All fifty-seven modules carry theirs. The structural guard
freezes each against the production vocabulary, fails when a module's own arms
disagree, and pins a non-zero count of resolved sections so a matcher that
stopped reading the argument fails instead of agreeing with everything.
`requireGuardianAuth` is exported and reaches nothing yet. It gates on the
managed-profile marker rather than on the grant, so an adult who granted
management of their own record cannot arrive at that record's settings by any
argument about what MANAGE means: widening MANAGE would widen the record
resolver and would not touch this one. Its frozen list lands empty, with the
declaration site as the positive control that keeps "nothing reaches it" a
measurement rather than a renamed symbol.
`users.managed_profile_at` says since when a record is one somebody else runs.
A timestamp and not a boolean, for a reason the schema has to keep possible:
clearing it is the handover, and the grants and the activity trail span it
untouched.
The fix that stopped a delegate overturning a recorded dose through the second
intake route landed on the trunk with no line in the notes. A change that
alters what somebody else may do to your record and says nothing about it is
the shape this project keeps rediscovering, and a release assembled from these
notes would have shipped it silently.
