The write side of the law, ruled 2026-08-03: data is either in main space
where developers can use anything, or it is in system.*.
- The reserved-name write door DIES: add/update/relate/updateRelation
metadata bags accept EVERY name (confidence, type, id, data, level,
content, ...) as ordinary user fields — indexed, filterable, sortable,
aggregatable, identical to any other field. The remap/enforce/warn
machinery, the reservedFieldPolicy config (now a typed init refusal),
and the compile-time metadata key bans are all removed. The one write
refusal left: keys spelled 'system.*' (namespace forgery), now enforced
on all four write doors.
- STORED RECORDS GO NESTED (v2): engine fields top-level, the user bag
nested verbatim under 'metadata', sealed by a format stamp — by-name
storage discrimination is unsound once colliders are admitted. Legacy
flat records stay readable forever through the shape-aware splitters
(sound for them: the old door refused colliders). Time travel rides the
same split (generation store snapshots whole records).
- Name-based index exclusions DIE: user frame indexes every name; the
excludeFields/indexedFields knobs and their silent-[] holes are gone;
bulk-payload protection is value-shape only, uniform across names.
- Consumer-sweep findings fixed in the same wave: per-type counts read
the frozen 'system.type' column (addToIndex sort, affinity tracking,
cold-count rehydration, VFS type bitmaps — legacy 'noun' fallback for
pre-rebuild reads); resolveHiddenIds addresses 'system.visibility'
(bare 'visibility' was a silent no-op under the law — VFS/system
entities leaked into default reads).
- Fidelity fallout fixed in the owning layers: readEntityFieldAddress
reads the bag first (colliders were absent-shadowed by its own guard)
and never serves system addresses from the bag; blob history refs read
the bag shape-aware; migration transforms now receive ONE normalized
view (engine fields + nested bag) regardless of stored era, and stray
flat-habit keys refuse with the fix in the message.
- THE REOPEN-COLLIDER CONFORMANCE CASE (required before any RC counts as
gates-green): all ten collider names + plumbing names written as user
fields, verified verbatim + queryable across live reads, flush+reopen,
a forced epoch rebuild, and asOf time travel; relation mirror; forgery
refusals; legacy flat-record compat. 8/8 green.
Gates: unit 1901/1901 (exit 0) · integration 758 (exit 0) · conformance
27/27 (exit 0) · consumer test sweep migrated (10 files).
A filtered + ordered find() materialized the FULL sorted match set before slicing
the page — passing k = filteredIds.length to the column store's filteredSortTopK.
A broad filter + orderBy returning 20 rows at billion scale produced hundreds of
millions of sorted ids to discard all but the page (O(matches) heap).
Thread the page bound (offset + limit + the hidden-tier over-fetch) into
getSortedIdsForFilter → filteredSortTopK / sortTopK / the sparse-path slice, so
the sort produces only the page. Ordering and pagination are unchanged.
