docs(testing): bring the test map up to release truth

Lands an orphaned-but-accurate working-tree edit (the engine table rows
for forbidden_apis.rs, lance_surface_guards.rs, traversal_indexed,
proptest_equivalence, ordering, literal_filters, policy_engine_chassis —
all real files; 21 -> 28 count) and replaces the stale pre-modularization
crate rows: the CLI and server entries now describe the per-area suites
(#192/#193 splits) plus this cycle's additions (RFC-008 deprecation
coverage, keyed-credential auth, hermetic OMNIGRAPH_HOME harness, the
bucket-gated s3 suites).

 | `merge_truth_table.rs` | Merge-pair truth table (MR-786): all 9×9 `(left_op, right_op)` cells from `{noop, addNode, removeNode, addEdge, removeEdge, setProperty, dropProperty, addLabel, removeLabel}`. Adding a new op to `OpVariant` forces a compile error in `build_case` until the new row + column are dispositioned. 36 executable cells run through real `branch_merge` with a structured oracle (`MergeOutcome` / `MergeConflictKind` + graph-state assert); 45 cells involving `dropProperty`/`addLabel`/`removeLabel` are recorded as `Unsupported` until the mutation grammar grows. |
 | `writes.rs` | Direct-publish writes: cancellation, non-strict insert/merge rebase under the per-table queue, strict stale-write conflicts, multi-statement atomicity, MR-794 staged-write rewire (D₂ rejection, insert+update coalesce, multi-append coalesce, partial-failure recovery, load RI/cardinality recovery) |
 | `staged_writes.rs` | TableStore staged-write primitives (`stage_append`, `stage_merge_insert`, `commit_staged`, `scan_with_staged`, `count_rows_with_staged`) — primitive-level only; engine code uses the in-memory `MutationStaging` accumulator instead |
+| `forbidden_apis.rs` | Defense-in-depth source-walk guard: engine code (`exec/`, `db/omnigraph/`, `loader/`, `changes/`) must not reach around the sealed storage trait to Lance inline-commit APIs; `// forbidden-api-allow: <reason>` sentinel exempts reviewed lines |
+| `lance_surface_guards.rs` | Pins the Lance API surfaces omnigraph depends on (named runtime + compile-only guards; see [lance.md](lance.md)) — the first smoke check on any Lance version bump; e.g. `compact_files_still_fails_on_blob_columns` turns red when the upstream blob-compaction fix lands |
 | `lifecycle.rs` | Graph lifecycle, schema state |
 | `point_in_time.rs` | Snapshots, time travel (`snapshot_at_version`, `entity_at`) |
 | `changes.rs` | `diff_between` / `diff_commits` |
 | `consistency.rs` | Cross-table snapshot isolation, atomic publish |
 | `schema_apply.rs` | Migration plan + apply, schema-apply lock |

+| `traversal.rs` | `Expand`, variable-length hops, anti-join (CSR path — `OMNIGRAPH_TRAVERSAL_MODE` unset) |
+| `traversal_indexed.rs` | BTREE-indexed Expand (`execute_expand_indexed`) forced via `OMNIGRAPH_TRAVERSAL_MODE`, asserted semantically equal to the CSR path; own binary, all `#[serial]` so env writes never race |
+| `proptest_equivalence.rs` | Property-based query-correctness invariants over generated graphs (shared key alphabet forces cross-type id collisions, cycles, self-loops) — pins Expand-mode equivalence so a future fork divergence fails loudly instead of silently; `#[serial]` |
+| `ordering.rs` | ORDER BY contract: descending, multi-key precedence, deterministic key-column tie-break (total order, so `ORDER … LIMIT` is deterministic), NULL placement (`nulls_first = !descending`) |
+| `literal_filters.rs` | Execution goldens for non-string/non-integer scalar literal filters (F64/F32/Bool/Date/DateTime) across both the in-memory comparison arm and the Lance-pushdown arm |
 | `aggregation.rs` | `count`, `sum`, `avg`, `min`, `max` |
 | `export.rs` | NDJSON streaming export filters |
 | `s3_storage.rs` | S3-backed graph (skipped unless `OMNIGRAPH_S3_TEST_BUCKET` is set) |
 | `lance_version_columns.rs` | Per-row `_row_last_updated_at_version` behavior |
 | `validators.rs` | Schema constraint enforcement (enum, range, unique, cardinality) across JSONL, insert, update paths |
+| `policy_engine_chassis.rs` | Engine-layer Cedar enforcement (MR-722): allow + deny through every `_as` writer via the SDK directly — no HTTP — proving embedded and CLI callers hit the same gate as the server, with action × scope shapes matching `authorize_request` |
 | `maintenance.rs` | `optimize` (compaction), `repair` (explicit uncovered-drift publish), and `cleanup` (version GC): empty/idempotent/no-op edges, policy validation, head preservation; `optimize` publishes its own compaction (`optimize_publishes_compaction_to_manifest_so_schema_apply_succeeds`), skips pre-existing uncovered drift (`optimize_skips_preexisting_manifest_head_drift`), and refuses to run while a `__recovery` sidecar is pending (`optimize_defers_when_recovery_sidecar_is_pending`); `repair` previews/heals verified maintenance drift, refuses raw semantic drift without `--force`, and forced repair publishes only by explicit operator choice |
 | `failpoints.rs` | Failure-injection coverage (gated on `failpoints` feature). Includes the five per-writer Phase B → recovery integration tests (`recovery_rolls_forward_after_finalize_publisher_failure`, `schema_apply_phase_b_failure_recovered_on_next_open`, `branch_merge_phase_b_failure_recovered_on_next_open`, `ensure_indices_phase_b_failure_recovered_on_next_open`, `optimize_phase_b_failure_recovered_on_next_open`). |
 | `recovery.rs` | Open-time recovery sweep — sidecar I/O, classifier dispatch (NoMovement / RolledPastExpected / UnexpectedAtP1 / UnexpectedMultistep / InvariantViolation), all-or-nothing decision, roll-forward via `ManifestBatchPublisher::publish`, roll-back via `Dataset::restore`, audit row in `_graph_commit_recoveries.lance`, `OpenMode::ReadOnly` skip path |
