V13-FE-022 — URL query codec slice note

Requirement: REQ-FE-URL
API/UI/Test: UI-URL-01 / T-FE-URL-01
Source: v60 deep-link/canonical route boundary; current frontend/src/shared/crud/queryCodec.ts.
Assumption: Each screen that consumes the codec can provide an approved field/operator allowlist from its resource contract.
Unknown: No active production screen currently wires this codec to router state.
Decision Required: FE/QA must approve per-resource filter/sort allowlists before enabling URL synchronization in a screen.

Applied boundary

Added optional allowlists for sort fields, filter fields, and filter operators.
When supplied, unapproved URL values are discarded and the approved fallback remains authoritative.
Preserved existing behavior for callers that have not yet supplied a screen-specific allowlist.
Kept URL state as a serializable query contract; no Pinia/server-state duplication was introduced.

pnpm test -- src/shared/crud/tests/queryCodec.spec.ts
PASS: 1 file / 3 tests (2026-08-12)

pnpm typecheck
PASS (2026-08-12)

The Slice remains IN_PROGRESS until a production screen supplies an approved allowlist and deep-link browser evidence is collected.
