# 0.6.16 candidate: four native platforms and original arithmetic outcomes

Release [PR 1400](https://github.com/kimjooyoon/meta-ontology-go/pull/1400) head
`51aa9b33a44c57e25602c3610e07b8b3616f796c` passed native readiness
[37850934750](https://github.com/kimjooyoon/meta-ontology-go/actions/runs/37850934750)
and publication conformance
[37850935148](https://github.com/kimjooyoon/meta-ontology-go/actions/runs/37850935148).
Canonical compiler CI subsequently passed; its original proof and merge are
recorded below. Publication and installation have not completed at this
observation; the installed public version remains 0.6.15.

The original readiness ZIP artifact 11581838433 (161,850,654 bytes) matched
SHA-256 `94382a65df3941a1cf4e1286b480dec29e27ef2e8abfeed2f914df775d35d6fb`.
The retained compressed subset contains four native receipts, 20 raw arithmetic
observations and eligibility. The original large ZIP was removed after verification.
`FILES.sha256` describes this retained subset, not the original GitHub ZIP.

The comparison decodes exact JSON numbers. All four clean native builds use
Go 1.27.1 and the exact PR head above. Each reports two identical binary/archive
builds. The five profiles on each platform agree with clean local source
`58c0c6f328bba18523e164857bd725c6f32db50f`: original source and case values,
source/plan identities, candidate ordering, rejections, partial five-attempt 1/4,
complete six-attempt 4/4 and saved replay; fault operands and locations;
independent outputs, producer-dependent blocking, original large integers;
complete native processes and zero new inference. The graph keeps six matched
outputs, one fault and one blocked activity across two rows. These 20 records
are repeated executions of two source examples.

`compare-platforms.go.txt` is the independent comparison. The repository's
[local candidate observations](https://github.com/kimjooyoon/meta-ontology-go/tree/51aa9b33a44c57e25602c3610e07b8b3616f796c/docs/research/release-0616-20261009)
retain the original local outputs, model run, test logs and exact-number recount.
No new model was trained for the release.

The independent comparison was then tightened to read the protocol's exact
`canceled` and `diagnostics_bytes` field names (the first helper used absent
`cancelled`/`diagnostics` keys). The same retained 20 originals passed again;
`process-fields-recheck.txt` records that comparison. The platform validators
already checked the correct fields. Source, cases and raw results are unchanged.

The changed-field controls additionally set cancellation and nonzero diagnostic
size on separate in-memory copies; both are rejected by the independent
comparison. The original files remain unchanged. The two controls and their
Go source are retained here.

## Validated merge

Canonical CI [37850934693](https://github.com/kimjooyoon/meta-ontology-go/actions/runs/37850934693)
passed all six jobs. Original proof artifact 11582652537 (11,192 bytes) matched
SHA-256 `34de5ed1d643aceb784222e3c140d7094f0d20230436d519cbd89906e4599530`.
The verifier checked provenance and the exact PR tuple. After main promotion
PR 1399 had merged, the original PR 1400 head and live dev base were checked
again. A normal expected-head squash merge produced dev
`146a5085427972f3a50c38b33384e3911c9019eb` at 2026-10-08T22:20:45Z.
Its tree matches tested head `51aa9b33a44c57e25602c3610e07b8b3616f796c`.
Original proof, run and merge observations are under `compiler/`.
