# STEP20C CORE recovery, OOM and DCC qualification
|
||
|
||
EXPERIMENTAL, source-only evidence for
|
||
`SWAYFX_MOSAIC_STEP20C_CORE_RECOVERY_OOM_AND_DCC_QUALIFICATION_BATCH_V1`.
|
||
Baseline: `70954e26f62fb3df25995e31b0c615762ff85a60`.
|
||
Private LAB: `/home/fy59/swayfx-mosaic-core-recovery-qmhckba5`.
|
||
|
||
This fixture adds no production dependency or implementation. STEP20A DONE;
|
||
STEP20B EXPERIMENTAL; STEP20C NEXT; STEP20D–G PLANNED;
|
||
PRODUCTION_MULTI_OUTPUT NOT_YET_SUPPORTED; PRODUCTION_AUTHORIZED FALSE.
|
||
|
||
## Evidence and scope
|
||
|
||
- [Graphics sources](graphics/README.md) preserve the new S0–S8 runner and
|
||
shared offline predicates. Nine runs, 102 output PNG, 120 reserved capture
|
||
slots, no retries, no compositor/GPU builds or staging. All runner exits0;
|
||
terminal IPC exits1 remain distinct. Scientific and mechanical cleanup pass.
|
||
- [GPU sources](gpu-field/README.md) repair the per-plane metadata predicate
|
||
and replay historical G1 without altering its outcome. Thirty-six tests pass;
|
||
the complete epoch still rejects `effective halfpixel`, read success is
|
||
NOT_PROVEN and the GL error queue is UNOBSERVED. New GPU runtime NOT_RUN.
|
||
- [OOM sources](oom/README.md) preserve A/B/C private prototype patches,
|
||
extraction bindings and C17 harnesses. Forty expected command results and
|
||
six rejected mutants are independently reproduced. Session survival and
|
||
native damage remain unproved; production OOM policy is UNDECIDED.
|
||
- [Results](evidence/results.json), [provenance](provenance.json), the
|
||
[durable budget snapshot](evidence/budget.json) and scoped review summaries
|
||
bind compact public metadata. Reviewer receipts are faithful structured
|
||
transcriptions materialized by the parent, not reviewer-authored files or
|
||
verbatim transcripts. Final deep review and actual publication identities
|
||
are recorded separately in the private post-publication closeout.
|
||
|
||
The nested fixture READMEs and source manifests retain their submission
|
||
edition, including then-pending reviews. The later scoped review receipts and
|
||
this directory's results record completed runtime/review evidence separately;
|
||
the frozen pre-run source bytes are not rewritten to update lifecycle labels.
|
||
|
||
Three published Python copies have one final blank line removed solely for
|
||
the new-file whitespace check. The [reversible normalization receipt](evidence/public-source-eof-normalization.json)
|
||
records both hashes, the exact suffix and equal AST/compiled bytecode. The
|
||
executed LAB copies and their accepted manifest are unchanged; those three
|
||
published files are not claimed byte-identical to the executed sources.
|
||
|
||
The historical LAB and its 4,688 entries remain unchanged. New sources have
|
||
their own parent hashes/deltas; historical failures are never reclassified.
|
||
The residual two conditional tokens do not authorize a retry or another run.
|
||
Every S identifier is consumed. The archived runtime launcher is evidence,
|
||
not permission to reuse this closed campaign.
|
||
|
||
Fullscreen cross-output remains NOT_EXERCISED: S5/S6 popups stayed inside H1,
|
||
and their ancestor child counts/owner heights differ. The raw vertical
|
||
`geometry.crossing` field retains its generic X/0 result; the executed Y/600
|
||
predicate and configured Y bounds establish the separate vertical crossing.
|
||
No raw source or receipt is edited to hide that metadata limitation.
|
||
|
||
## Offline reproduction
|
||
|
||
The following commands read retained historical/private evidence and launch
|
||
no compositor. Use `-B` to avoid changing historical directories with caches.
|
||
Choose a new, absent output filename for each audit or collection receipt.
|
||
|
||
```sh
|
||
python -B -m unittest discover -s tooling/probes/step20c-core-recovery/graphics -p 'test_*.py' -v
|
||
python -B -m unittest discover -s tooling/probes/step20c-core-recovery/gpu-field -p 'test_*.py' -v
|
||
python -B -m unittest discover -s tooling/probes/step20c-saved-input-gpu-batch -p test_native.py -v
|
||
python -B tooling/probes/step20c-core-recovery/audit.py --output /tmp/new-core-recovery-audit.json
|
||
python -B tooling/probes/step20c-core-recovery/collect.py --lab /home/fy59/swayfx-mosaic-core-recovery-qmhckba5 --output /tmp/new-core-recovery-collection.json
|
||
```
|
||
|
||
See the OOM README for a new private extraction/test directory; never rerun
|
||
its generators into the frozen evidence directory. Full source forks,
|
||
generated protocol files/slices, compiled clients/harnesses, ELF files, PNG,
|
||
DMA-BUF data and large logs remain outside Git. This is not a standalone
|
||
redistributable build kit, an OOM policy adoption or a production release.
|
||
|
||
The [V3 decision](../../../docs/design/STEP20C_CORE_QUALIFICATION_DECISION_V3.md)
|
||
provides the scientific interpretation and open integration gates.
