Temporal support: the anchor is only part of the missingness

12 October 2026. The separately frozen post-comparison diagnostic is complete and independently recomputed. Only 3 of 27 consumed qualifying chemistry-positive cases have sufficient available-field-screened cadence in their original NEOWISE query cone. The descriptive majority gate, 14 of 27, failed. None has the original anchored temporal view. Removing the anchor alone would therefore leave 24 of 27 without this query-level support, and would not validate even the remaining three as single-emitter light curves.

This is a selected-cache missingness diagnosis, not a new protostar classifier, physical validation, variability event or birth. The completed embedding result remains 14/27 versus the nonlinear baseline’s 15/27 at 18 equal-cost reviews. No fit, original threshold, input feature or ranking score was changed.

Exact positive-cohort decomposition

All 27 are requested by the original temporal query. The failures partition without overlap:

Diagnostic outcome	Positive-reference cases
Requested, no cached rows	11
Cached rows, none passing the unchanged screen inside the query	9
Screened query rows, insufficient original cadence/span	4
Query cadence supported, retained qualifying anchor absent	2
Query cadence supported, anchored cadence insufficient	1
Original anchored cadence supported	0
Total	27

The new primary count is 3/27 = 11.11%, a deterministic count of these consumed, selected references; it is not a sky-population rate or confidence bound. No physical precision, population recall or stellar occurrence fraction is measured. Missing cached rows do not prove absence of observations in the survey, nor do failed screens prove a starless clump. No new observations were acquired.

The diagnostic used the original 6-arcsecond query cone, SNR >= 5, positive quoted error, qual_frame > 0, nb == 1 and a clear retained W2 artifact flag, with valid coordinates/epochs/magnitudes. Exact five-string tuples were deduplicated. A gap > 30 days separated visits; each supported visit required at least five tuples, with three supported visits and >=365-day total span. The original <=3-arcsecond AllWISE anchor and <=2-arcsecond measurement-to-anchor path was separately reproduced and unchanged for every parent object.

Query-level cadence can mix emitters and artefacts. Missing positional errors, native source/exposure IDs, alternative AllWISE counterparts, chi-square, moon, saturation and solar-system fields remain unverified. These counts cannot be used directly as temporal features for a repaired classifier.

All requested identities, selected support and controls

The ledger retains all 19,328 nearby catalogue-prestellar parent designations, including 109 not requested in the original query. The original 1,250,385 cached measurement rows are hash-bound and preserved. The exact original proxy-state strings and an explicitly separate semantic group are both recorded.

Consumed proxy group	Objects	Query-level cadence supported	Original anchored support
Qualifying chemistry positive	27	3	0
Qualifying proxy negative	235	14	3
Unknown qualifying proxy state	19,066	2,996	758
Entire requested parent	19,328	3,013	761

Across the parent, query cadence is broader than anchored support. That does not establish ownership, physical classes or complementary information in an independently evaluated positive sample. Unknowns remain unknown; the 3,013 are not a new list of young stars. The original 761 anchored-support cases are exactly reproduced, including their duplicate counts, visit counts and spans.

Descriptive support tables were frozen for longitude tiles and parent-median mass, temperature, distance, surface density and diameter. The parent medians are mass=43.8, temp=11.0, dist=2.21, surf_dens=0.14 and diam=0.28 in the untransformed source fields. All 27 positives exceed both the mass and surface-density medians; 22/27 exceed the temperature median. None of their low-mass/low-surface-density analogue coverage is established. Chemistry proxy support therefore cannot represent the whole requested population without further evidence. These are selection diagnostics, not causal adjustment or validated extinction/column-error controls. Molecular sharing indicators remain in each source row; emitter crowding and physical clump membership remain unresolved.

Three evidence cases, not new candidate discoveries

These three consumed positive references have query-level cadence. Their original raw rows, including failures, are retained in the 1,072-row positive-evidence export alongside the other 24 positives. No event or photometric fit was made.

Hi-GAL designation	Query unique screened tuples	Supported query visits	Why original anchored support is absent
HIGALBM330.8814-0.3656	201	21	No qualifying retained anchor
HIGALBM351.2258+0.6937	145	19	Only one retained measurement matches the qualifying anchor
HIGALBM353.4272-0.3734	90	6	No qualifying retained anchor

Their query spans are about 3,651–3,653 days. That is observing support in a cone, not the duration or measured variability of an identified star. They may inform a future source-identity assessment, but no such assessment, new ranking test, acquisition or successor experiment follows automatically here.

Preserved failed attempt, independent check and resources

The first implementation stopped before reading native epochs because it expected semantic proxy labels instead of the ledger’s native labels. The original freeze ed114aad, failure log and resource receipt are preserved. A separately committed lossless schema amendment, e75ad9ed, retained native labels and added an aggregation-only group. Population, screen, association, cadence and primary majority gate were unchanged before the new readout.

The independent checker imported no worker functions. It streamed the original rows in four ordinal shards, used unit-vector atan2 geometry instead of haversine and exact tuple sets/gap-index boundaries instead of packed buffers. It verified all 19,328 IDs and every ledger field, membership hash, original anchored metric, covariate/longitude table and all 1,072 positive raw rows. This is independent software recomputation, not independent physical truth.

The worker completed in 9.30 seconds with peak sampled RSS 210,337,792 bytes (200.59 MiB). The checker completed in 15.48 seconds at 189,595,648 bytes (180.81 MiB). Every recorded memory-pressure sample was normal. Their minimum observed free disk space was about 53.94 GiB, above the 5 GiB reserve. RSS samples can miss short peaks. Combined output is under 2 MiB, below the frozen 16 MiB cap; the final checkpoint inventories exact bytes. No observations were deleted, downloaded or uploaded; no GPU, paid cloud job or private Atlas action occurred.

Conclusion and stopping

The completed diagnostic rejects the hypothesis that original-query cadence exists in a majority of these 27 positives. The missing temporal view is not merely an AllWISE-anchor artefact: cached absence, available-field screening and cadence account for 24 cases. In the remaining three, identity and reliability still require evidence before temporal/gas complementarity can be tested. The fixed comparison stays negative; weaker association rules cannot supply its missing information or independent physical validation.

This unit stops here. A defensible next scientific decision concerns source ownership and a representative independent validation route, not a model sweep on these same proxy labels. Any distinct evidence test needs its own prospective protocol; no acquisition, relaxed cuts or automatic successor is authorized by this result. The week-long program and full detector goal remain unachieved. No new star, confirmed birth, hidden fraction, lifetime or robust detector exists. The 333/800 occurrence gate, unopened readout, N20/c6828 stops, E29–E160 archive and private Atlas/E155/E121 restrictions are unchanged.

Historical generation-time pending flags remain preserved; the independent receipt and final checkpoint establish completed checking. This local scientific result is unpublished until a separate exact public deployment receipt exists.
