# Fixed SEGMENT task and explicit degraded coverage **R4 local runtime, archive and import checks completed; official platform qualification remains unproven.** The exact archive is `e477d307ff2e09f469d83569ec1ce8703daeef34edbba633a3f240eab955de00` (35,613,293,722 bytes), immutable generation `1789092734891901`. The build manifest is `ba9ddb1e78a45040803ae6f0e68c66de7a538f5e3e86397777e5fc2c488106b0` and configuration `3f43fce1081dc5db454447dbe4678947e5cefec014635e611d8d1032a0ac71c4`. Full compressed/raw archive verification covers all 26 ordered DiffIDs; actual same-generation classic Docker import reports config `3f43fce1081dc5db454447dbe4678947e5cefec014635e611d8d1032a0ac71c4` and no imported manifest digest. The agreed eight cases completed 9 application invocations and 1593 answer executions across 533 unique qIDs. Healthy20 and loose/ZIP500 matched saved content; reverse20 matched the same-image ordinary20, and both ZIP quotas matched the same-image loose500. Canonical repeated calls retained the exact disclosed deferrals. The mixed recovery case blanked only its declared failed questions and preserved later healthy outputs. These are bounded runtime/interface/content checks; no new semantic grade or official final result is claimed. R4 retains the image-owned literal SEGMENT task and the original request clocks. It stages only the selected ZIP member for each startup probe or answer, verifies that member through CRC/EOF and SHA-256, closes decoder handles, and removes the lease before continuing. Loose input remains a direct read. Model initialization is still eager. An attributed ordinary per-question exception produces empty content for that qID with measured latency and failure telemetry; successful answers are preserved and later questions continue. Unsafe or ambiguous archives, source mutation, cleanup integrity, required model initialization, environment and fixed-track failures remain fatal. The inherited precise pre-generation rules deferrals remain separately disclosed as degraded coverage. The four changed image files are the bootstrap, contract, probe entrypoint and new ZIP helper; all 51 unchanged inherited serving source files, including cap_fmt, all 50 model/prior assets, prompts, model arithmetic and generation settings remain unchanged. The full retained ZIP500 was qualified locally at the stated 4 GiB and 16 GiB tmpfs profiles, alongside loose500, healthy20, reversed20, default and persistent canonical calls, and controlled recovery. These fixtures do not establish the platform scratch quota, all possible input sizes, continuous resource peaks, cold-cache requirements, general order invariance, new semantic scores, independent-holdout performance or official platform success. Canonical deferrals and deliberately failed recovery rows are reduced scientific coverage. The prior R3 4 GiB eager-ZIP failure is a conditional local capacity reproduction, not proof of the organizer failure cause. Earlier images and failed attempts remain historical. The earlier 43d4 qualification covered six H100 invocations and 600 answer executions across 520 unique questions, including repeated20 cases and a loose500 case. It omitted the owner canonical long intervals and invalid-media control. Its151 positive 500 startup probes left 349 unmeasured; its ZIP coverage was 20, not 500. Those measurements remain historical and do not qualify R4. The completed R2 diagnostic prototype returned 10 answers twice with identical contents but failed its guard on two adaptive_n duration-domain deferrals and one no-frame control. That interface diagnosis is not an all-neural-health pass. The exact four R4 image files are available for inspection under platform_wrapper/. The inherited component_source/cap_fmt_inferrer.py and all component loaders remain unchanged. R4 retains the image-owned literal SEGMENT task and the original request clocks.
