# Minimal private core gate — preserved experimental fixtures
|
|
|
|
This is the source archive of the consumed
|
|
`SWAYFX_MOSAIC_STEP20C_MINIMAL_CORE_BUILD_RUNTIME_AND_GPU_FIELD_GATE_V1`
|
|
campaign, not a production dependency or a new execution authorization.
|
|
Scientific result: **PARTIALLY_ADVANCED**. Recommendation:
|
|
**PRIVATE_CORE_NEEDS_TARGETED_EVIDENCE**. STEP20C remains NEXT;
|
|
production multi-output remains NOT YET SUPPORTED.
|
|
|
|
The private laboratory is `/home/fy59/swayfx-mosaic-minimal-core-2l7riqt_`.
|
|
The ledger has 12 distinct consumed runs out of 14, 88 output-capture debits
|
|
out of 180, one initial core build per component, one diagnostic GPU build
|
|
pair and one DESTDIR stage. Failed attempts remain consumed. The two optional
|
|
slots are not retry slots. No existing run, build, stage or test is to be
|
|
repeated under this archive. No production installation was performed.
|
|
|
|
## Contents and provenance
|
|
|
|
`provenance.json` binds every copied file byte-for-byte to the private LAB and
|
|
references the larger immutable manifests and receipts by SHA-256. Generated
|
|
extracted `.inc` bodies, functional private core patches, fork sources, clients'
|
|
binaries, build trees, PNG captures, raw GPU readbacks and large logs remain
|
|
outside Git. This is deliberately not a self-contained compositor source kit.
|
|
|
|
- `c-tests-fixed/`: C17 geometry tests and exact-byte extraction/command
|
|
scripts. The private finite-scroll correction passed 184 assertions in
|
|
normal, UBSan and ASan+UBSan variants; the original six UB reproductions
|
|
remain in the LAB. Extraction requires `mosaic-fixed/` and `scene-core/`
|
|
under the private LAB and generates the excluded core bodies. The reduced
|
|
adapters do not reproduce full compositor ownership or ABI.
|
|
- `c-tests-lifecycle/`: real core slice extraction and reduced adapters using
|
|
native Wayland listeners and Pixman regions. Ordinary variants passed;
|
|
targeted sidecar allocation failure terminated each variant with raw
|
|
`-6 / SIGABRT`. **OOM_ABORT_EXPERIMENTAL**, availability risk P1, is not an
|
|
accepted production contract. Its README describes the exact coverage and
|
|
the preserved first fixture failure.
|
|
- `graphics/`: the final R2 Python fixture sources, sealed configurations,
|
|
C17 client/protocol sources, input trace fixture and bounded repair tests.
|
|
`run.py`, `gate.py`, `prepare.py` and `seal.py` retain historical laboratory
|
|
assumptions; moving them does not establish a valid source freeze, binary
|
|
identity, accepted independent review or durable ticket ledger.
|
|
- `gpu-field/`: frozen readback validator, analysis and offline test source.
|
|
`test_native_hash.py` requires the excluded diagnostic header under
|
|
`scene/render/fx_renderer/gpu_field_private.h`; its earlier ten CPU hash
|
|
cases passed, but no new execution is claimed by preservation.
|
|
- `evidence/`: final consumed budget, independent E/F review transcription,
|
|
GPU rejection/layout audit, local ABI provider summary and the separate
|
|
correction of an aggregate R2 exit-count error. Transcriptions are labelled
|
|
as such; original runtime receipts are unchanged.
|
|
|
|
The exact core binary is
|
|
`29baf31aa3eeed259825c87d0799fa5d3dc83710afb967154604eb1c6657f965`
|
|
(Build ID `1b42e557e38db3440ae8dcf7ac967e4132223365`). The GPU diagnostic is
|
|
`1905a20fa72ebcc7ec47d1584a4653654280288096a20005199eb75673ac0383`
|
|
(Build ID `1505e31c3dc08d2a7799c2ee9e1b2705eb61f5fe`). Their runtime data
|
|
are distinct. Both used the measured wlroots library
|
|
`7edca9a7d65855addda68e29ba5db94d57c803eb5fa7d0f86db3136b90ca9837`.
|
|
|
|
## Recorded execution and limits
|
|
|
|
The historical C commands were `python run.py` from the corresponding private
|
|
C test folder; each command, stdout/stderr and raw return code is retained
|
|
there. Graphical runs were reserved through `python -B graphics/run.py <ID>`
|
|
and the sole G1 through `python -B gpu-field/runner.py`, with private runtime
|
|
directories, sockets, reviewed byte freezes and local/global debits. These
|
|
commands describe consumed evidence; they are not instructions to launch again.
|
|
Any future reproduction requires a separately authorized scope and budget,
|
|
exact parent replay, new private source/binary identities and independent gates.
|
|
Never point these scripts at a daily desktop socket or reuse a consumed token.
|
|
|
|
E0 controls and the vertical cell stopped before captures on a fixture error.
|
|
E1's first chain, fractional/R90 and resize/migration provide sampled evidence;
|
|
standard return and fullscreen policy are not qualified by comparable controls.
|
|
E5's chain was dismissed by outside input before camera return. E6 observed a
|
|
natural timeout before late ACK, but its frozen validator still failed.
|
|
E7 classic blur was exercised; shadows were not. Whole-H1 A/A-return retained
|
|
33,789 different pixels without mask or tolerance. Exact sampled H2 does not
|
|
prove complete damage, native saved identity, GPU lifetime or atomic generation.
|
|
|
|
G1 stopped after nine first-A sample records and 8,312,048 raw bytes because
|
|
the frozen validator rejected the auxiliary DMA-BUF plane stride. No accepted
|
|
epoch receipt, B/A-return epochs or causal analysis exist. Read success remains
|
|
NOT PROVEN, the GL error queue UNOBSERVED and whole-field causality INCONCLUSIVE.
|
|
The modifier audit explains the invalid per-plane stride assumption without
|
|
changing the validator, accepting rejected bytes or refunding the run.
|
|
|
|
Runner exits, terminal IPC exit 1, compositor/client exits and normal client
|
|
closure are separate evidence. A runner's `scientific_cleanup=PASS` here is its
|
|
process-recovery gate; E1/E6 normal close was not acquired and E2 helpers show
|
|
error 32 despite nested owners closing normally. G1 scientific cleanup remains
|
|
INCONCLUSIVE. Mechanical process recovery alone is not a GPU lifetime proof.
