The scope-fence test asserts that a refused section leaves a
sharing.access.denied audit row naming the reason. That row is written
without being awaited, on purpose, so the audit never delays the 403 the
caller is waiting on, and it lands some time after the response returns.
The test bridged that gap with a fixed 150 ms sleep, which a slow runner
outran: the read found an empty table and the assertion reported no
refusal, which reads exactly like the section having reached the wire,
the one thing this file exists to catch.
The positive case now polls for the row and fails with a message naming
the caller when none arrives within five seconds. The absence case keeps
a fixed wait, longer than before, because an absence claim is only worth
something if it waited. Proven by dropping the audit write behind an env
flag: eleven cases fail with the new message, and pass again with the
write restored.
- evaluate the fence in the wrapper above findCached, so a stale request
neither replays a body, learns a cell exists, nor inserts a claim
- return the refusal rather than throwing: one route composes the
wrapper outside apiHandler, where a throw escapes the envelope
- read the claim and the session's own context on one session lookup
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.
