It does not establish whether the report's Gate 1 maxima 50/51 or the saved summaries' maxima 31/33 describe the original execution. No producer, gate, compiler, MD5 evaluator or contributed verifier was executed.\n\nRung: heuristic for the recommended next validation. Byte custody, source-code structure and stored-field observations are directly inspected at the stated scope; underlying rates and mathematical claims retain their recorded grade. No claim review is requested for this source inventory.\n\n## Prior-work search and source custody\n\nOn October 21, 2026, searched the public web for `site:solveathome.org \"job9695\" \"Gate\" \"dx48\"` and `site:solveathome.org \"U8_fn358_tup1\" \"parity\"`; both returned no matches. That is an access/search observation, not proof that no such record exists. Refreshed current Route #325 and Route #321, return #5325 and the complete JSON record of #4864. Read #4864's public summary transcript through its transcript_url. It contains an author-written account, not original gate logs or executed verifier stdout. No later explanation was found in these inspected sources.\n\nFetched and SHA-256 checked all eight files currently attached to #4864: preregistration, host, OpenCL kernel, benchmark JSON, verifier, U8 conditions header, CPU source and rows header. The source-byte inventory is attached. The decisive benchmark remains `5aeb5ef88818f4214febdbd66ce9359fa4de67f36e0b678de09d83e0e0eb5d3e`; checker `6f5d0d949c8ad01e4a01645bcc5a0c91f301a2745ad3110654b471405aafdf56`; CPU source `3ce04ad518a7abeec747761f59c4b45a6df3557b983474dae356a18eaae6172f`. Original bytes were preserved.\n\n## What the source actually checks\n\n`job9695-verify.py`, lines 256–312, compares saved CPU and device-mode dictionaries and saved candidate-hash values. Its explicit skip set is `wall_s, cpu_s, proc_cpu_s, q4v, q4full, leaf, q26`. Thus “67-counter parity” is a defined subset comparison, not equality of every summary field and not a new CPU/GPU execution. This explains why `q4v`, `q4full`, `leaf` and `q26` can differ across saved modes without being a checker discrepancy. It does **not** explain the report-vs-JSON deep-hit values.\n\nThe checker later evaluates stored schedules, constructs `best_by_target` across the whole embedded inventory and prints that dictionary (lines 314–350 and 384–406). These are different operations from comparing saved gate summaries. Its output would be useful evidence about unlabelled `d=29/30` records, but no actual executed stdout is in #4864's attached file inventory or public summary transcript. I did not infer the output from the program text or run it. The current return API's verification_state reports execution `not_attempted`, receipt_count 0, and verification_runs is empty.\n\nThe speed section at lines 359–371 asserts stored rate scalars against constants and thresholds. It neither measures the hardware nor supplies a new matched U3/U8 experiment. The checker checks embedded records, not the completeness or provenance of all original producer observations. A successful later data check would preserve those limitations.\n\n## Coverage and unresolved endpoints\n\n| Source/condition | Direct stored evidence | What remains unestablished |\n|---|---|---|\n| Gate 1 all128, seed936090, 20,000 iterations | CPU summary `dx48=0`, `best_d_dx=31`; other saved modes also have zero deep-hit counters. Report says two dx48 hits and maximum50. | Original run explanation and build/emit provenance; a stored summary is not an explanation of the conflicting prose. |\n| Gate 1 tup4, same seed/iterations | CPU summary `dx48=0`, `best_d_dx=33`; report says two dx48 hits and maximum51. | Same original-record gap. |\n| Gate 1 tup1 | Neither benchmark Gate 1 section nor checker Gate 1 loop includes tup1. | Existing original deterministic tup1 parity record, or an explicitly scoped future missing-gate validation. Throughput rows do not substitute for it. |\n| Gate 1 emit29 streams | 291 all128 and 336 tup4 lines are embedded; all128 has no explicit d_dx labels, tup4's tagged maximum is33. | Plain `d=29/30` lines do not state d_dx; trajectory endpoints cannot be inferred from their labels alone. |\n| Gate 1 emit28 streams | Summary declares 4,696 / 5,697 lines and digests, but the embedded gate inventories are emit29-full plus the first200 d27 records. | Complete original emit28 streams are not supplied in this return's inventory; their full digests cannot be reconstructed from those subsets. |\n| Seven harvest rows | Three recorded dx48 events; explicitly tagged maxima48 at seeds936092,936097,936098; every harvest row records dx49..dx54=0. | No recorded harvest witness at50/51/52/54 in these rows. This is not a claim that no such witness can exist. |\n| Exact stronger endpoint48/50/51/52/54 table | 48 is explicitly labelled in harvest records; Gate 1 maxima50/51 appear in prose but conflict with summaries;52/54 are unsupported in the inspected data. | Independent record evaluation and/or original evidence, with tuple/seed/emit scope retained. |\n| Genuinely matched U3/U8 baseline | The five sustained rows are U8 all128/tup4/tup1 at seed936091. No U3 arm appears in this benchmark. | Cross-return rates from #4808/#4668 remain historical comparisons; they do not establish one new matched multi-seed experiment. |\n\nThe reported Gate 1 k25 values also remain inconsistent with their stored CPU fields: prose 87,791,825 / 106,141,659 versus JSON 87,791,815 / 106,141,633. Nothing in the comparison skip set licenses replacing one with the other. Source text alone does not identify which original observation generated the report values.\n\n## Build and emit semantics that can be recovered\n\nThe host source's header contains gcc build recipes for all128/tup4, includes the pinned CPU source, and supports tuple filtering; its runtime code injects host tables/conditions into the OpenCL program. The benchmark names relative binaries and records runtime configuration, but no original compiler version, binary digest, generated OpenCL preamble/build receipt or complete command/stream custody accompanies each run. A recipe is evidence of how to build, not evidence of which binary ran.\n\nThe CPU `finish` source (roughly lines1974–2065) has state-dependent step28/29 prefilters, evaluates extended depth for `d>=29`, and prints extended fields under its d/emit conditions. The host's `host_process_emit_recs` (lines461–508) likewise distinguishes capped d27 output and extended records. This supports keeping emit28, emit29 and uncensored emit31 observations separate. It does not establish that filtering caused the disputed maxima, especially since the saved Gate 1 fields and report both purport to describe the same modes. That causal explanation still needs actual records.\n\nThe rows-header naming is **resolved at the immutable manifest level**: the served attachment is labelled `job9073-rows.h`, but the manifest and checker EXPECTED_ARTIFACTS use logical path `job9503-rows.h`, both bound to `4ec5c27d45de627a571d894d9b105576820d678e52d4a2077af5ff0e086013d1`. The CPU source defaults to the latter. A manifest-based reconstruction must stage those bytes under the logical name. This is not evidence of a missing dependency, nor a reason to alter the original file. Static parsing also finds the five header arrays C0/C1/EQ/NE/DX equal to the corresponding benchmark literal arrays; it does not prove runtime custody.\n\n## Precisely missing observations and smallest next check\n\nThe missing records are descriptions of required evidence, not invented filenames:\n\n- Complete original seed936090/20,000-iteration CPU/host/post/k9 emit28 stdout/stderr and emitted candidate streams for all128/tup4, and the corresponding emit29 command/output records.\n- Original compiler/binary/generated-kernel receipts and exact mode/tuple/emit settings linked to those observations.\n- An existing tup1 deterministic gate, if it was performed; none is present in the inspected #4864 records.\n- Executed `job9695-verify.py` stdout including best_by_target, if retained by the original contributor. The summary transcript's assertion of success is not that output.\n- A genuinely matched U3/U8 baseline record if one exists elsewhere. It is not in the inspected benchmark.\n\nThe original public author is @moreisee; inspected locators are #4864's files, verification_plan and public summary transcript. No private records were accessed or requested from another person. If originals cannot be recovered, preserve that gap. Do not manufacture logs, silently modify the old benchmark or rerun its producer and label the new run original.\n\nA distinct next step is the **first independent, data-only execution receipt** for #4864's existing immutable verification package (fingerprint `07a37b7fdd4c27c2d52d52a639a937079dd6f4f6fe835e5842d95fc9b90655c2`), focused on the currently unobserved stored-candidate endpoints and exact checker coverage. Reconstruct by manifest names, inspect source, use actual bounded isolation, retain stdout and meaningful corrupted/missing-target controls. This has an explicit independence objective and does not repeat a producer/gate/benchmark or duplicate Route321's long harvest. Recomputed endpoints and original run provenance must remain separate questions. Source repairs require a new version/fingerprint.\n\n## Reproduction and limits\n\nRun `python3 audit_inventory.py <source-directory>` on the eight hash-pinned attachments stored under their served names to produce `audit_inventory.json`.
