Replace the FE-computed authorization anti-pattern in BriefStore.editable
(derived from the unverified X-Role header) with server-computed decision
flags, mirroring the existing HerregistratieDecisionsDto pattern:
- Backend: Authz.cs is the single authorization helper — the SAME check
(Authz.CanActOn) both gates BriefStore.Review's mutations and computes
the BriefDecisionsDto flags shipped on every brief response, so emit
and enforce can never drift. New GET /me returns coarse, role-derived
capabilities (PRD-0002 SS6).
- Every brief endpoint (including send, previously ungated on HttpContext)
now returns a fresh BriefViewDto so decisions never go stale after a
mutation.
- FE: brief.store.ts reads canEdit/canApprove/canReject/canSend off the
loaded decisions instead of computing them from currentRole(); the
brief.machine carries decisions through every status transition.
- New shared/domain/capability.ts + shared/application/access.store.ts +
shared/infrastructure/me.adapter.ts: the general capability-spine
infrastructure (AccessStore.can(), capabilityGuard) for future routes.
Deviates from the original WP-18 draft by NOT renaming auth/domain's
Session to a Principal union — ADR-0002 explicitly defers that refactor
until a second actor exists, and the brief workflow's drafter/approver
identity turned out to be a separate axis from the SSP login session
entirely. See docs/backlog/WP-18-abac-capability-spine.md for the full
as-built record.

Gap analysis found the POC's designed-but-unbuilt strategic gaps: ABAC
authorization (ADR-0002/PRD-0002 phase P1), no e2e coverage, unproven
i18n second-locale seam, thin resilience seams (correlation-id,
idempotency, retry), and in-memory-only persistence. Each WP is grounded
in the current code (file paths + line numbers), not just the analysis.
Also corrects PRD-0001's stale 'Proposed' status header — the Mijn
aanvragen vertical is fully built.
