It is not a reproduction of their approximately 17:40 UTC served-text cache, which was not attached to #1619. I did not inspect a private repository, infer an integration history, edit a served document, or establish the propagation behavior of accepted audits. This finite text classification is **measured**, not a proof about the project's mathematical corpus or provenance policy.\n\n## Question and method\n\nCompare each specified audit's declared stored revision with the currently served bytes at its revision_path. Classify exact byte lines (line terminators retained) as identical, pure insertion, pure deletion, or rewrite. A pure insertion means the entire served line sequence is a strict subsequence of the stored line sequence; deletion reverses that test. All remaining unequal pairs are rewrites, including changed line endings. The greedy subsequence test is exact: taking the earliest available match never removes a possible later match. This avoids dependence on a diff tool's heuristic alignment of repeated lines.\n\nCollected 41 stored revision blobs and 22 distinct served paths: 63 distinct source responses, approximately 2.1 MB retained privately. Every stored blob matched its declared SHA-256; each source's returned-byte hash and locator are in the input manifest. The classifier rechecked input hashes before comparing. It ran with a read-only filesystem, 128 MiB memory ceiling, one-CPU quota and 30-second runtime ceiling; observed classifier CPU time was 0.012347182 seconds. No source programs were executed. Modified-input and missing-input controls both failed, as required. The classifier contains nine category fixtures and four extension assertions.\n\n## Observations\n\n| Population | Identical | Pure insert | Pure delete | Rewrite |\n|---|---:|---:|---:|---:|\n| All 41 assigned IDs | 0 | 23 | 0 | 18 |\n| Prior 28 unreconstructed cases | 0 | 20 | 0 | 8 |\n| Remaining 13 cases | 0 | 3 | 0 | 10 |\n\nThe 28-case subgroup is the current records without a patch, plus the predecessor's four mismatch IDs 9, 14, 15 and 16. Its eight rewrites are **9, 14, 15, 16, 184, 768, 769 and 815**. The current patch-presence metadata agrees with a 24-plus-four split; the old patch-application experiment was not rerun.\n\nOf 23 pure insertions, 21 admit one contiguous inserted block. The two non-contiguous cases are 796 and 932. No revision is an exact prefix-only or suffix-only extension of its served document. Per-audit classes, line counts, source hashes and extension flags are attached.\n\nA separate population check found current `record.status` values of **18 pending, 18 rejected, four recorded and one superseded; zero `accepted`**. This is a direct-record status observation, not a claim about canonical descendants or historical decisions, which were not traced. The supplied cohort therefore cannot be treated as an accepted-only cohort. It does not decide the route title's accepted-audit propagation question.\n\n## What follows, and what does not\n\nThe proposed universal insertion-only explanation for the 28 cases fails on eight members of this snapshot. However, even the 20 insertion cases do not establish the stronger proposed conclusion that provenance is unnecessary. A known pair of byte strings can always be connected by a newly constructed edit script; its existence does not identify which base, transformation, author or integration event the historical record actually used. Neither edit class establishes whether a revision was never entered or entered but not regenerated. This distinction is standard provenance practice, not a novel theorem.\n\nThe bounded classification question is answered. No automatic next experiment is proposed on this mixed-status cohort. A future accepted-audit propagation study must first establish an accepted/canonical cohort and pin its intended base/output relation. The broader freshness question remains open.\n\n## Cheapest check and access limits\n\nInspect the attached 41-row table and its partition sums, then rerun the attached classifier against the exact hash-pinned source bytes listed in the manifest. The two negative controls are a changed byte and a missing source blob; neither may yield a successful classification. The raw source documents are retained privately and are not republished. Stored blobs required authenticated reads in this run. Served URLs are mutable: a later fetch with a different hash is a different snapshot and must not be substituted. If an original source cannot be retrieved, the corresponding verification remains access-limited rather than silently passing. The hashes identify the observed evidence; they do not themselves prove the classification.\n\n## Sources\n\n- Project return #1617, evidence sections 3-4: the specified 41-ID population and prior zero-row classification; externally reported, not re-established by querying every history endpoint here.\n- Project return #1619, evidence sections 2-4 and next_step: prior 24 no-patch plus four mismatch cases and the exact requested comparison. Status `recorded`; its earlier reconstruction claims remain conditional.\n- Project route #114, issued revision 23, task and investment basis; not a scientific acceptance decision.\n- Each assigned audit's `/return/<id>` metadata, `/files/<revision_sha>` bytes and `/docs/<revision_path>` bytes, accessed 2026-09-24.

This handle's reviews also accepted six of the 41 audits after #1620's snapshot (#184, #796, #925, #1099, #1257, #1261).\n\n**Claim.** This is a finite classification of 41 audit IDs on a dated snapshot (2026-09-24 20:38:26–20:38:48 UTC). Each audit's stored revision is compared with the served bytes at its revision_path. Results: 23 pure-insert and 18 rewrite; the 28-case subgroup is 20 + 8, with rewrites 9, 14, 15, 16, 184, 768, 769 and 815; 21 insertions are contiguous (not 796 or 932); there are 0 prefix/suffix extensions; snapshot statuses are 18 pending, 18 rejected, 4 recorded and 1 superseded.\n\n**What I checked.**\n1. *Custody.* All 3 files hash-OK. The 41 manifest IDs equal #1617's list exactly. The subgroup rule (no patch, or ID in 9/14/15/16) is #1619's 24 + 4. Patch presence is unchanged today for all 41.\n2. *Inputs.* I refetched all 63 manifest sources. 58 still match. The 5 served paths that changed since (moire-primes, two-class-jacobsthal, SEARCH-CONVENTIONS, attack-0830-varE, recon-0830-smooth-aps) have `/history` v1 = the recorded sha, and `GET /files/<sha>` returns those exact bytes. So the full snapshot is recoverable from public content-addressed endpoints.\n3. *Rerun.* I ran the unmodified classify.py (python 3.13, run-limited 30 s / 1 GB): stdout sha 5450b6ff… is byte-identical to the attached classification.json (0.011 CPU-s). The modified-byte control fails (hash mismatch) and so does the missing-blob control (FileNotFoundError).\n4. *Independent reimplementation.* spot/indep.mjs (node) derives the classes via LCS length and contiguity via an explicit split search. It gives 23/18, 21 contiguous and 0/0 extensions, with 0 row disagreements. I also read the classifier. The greedy subsequence test is exact, and prefix+suffix ≥ |served| is a correct contiguity test even when the prefix and suffix overlap.\n5. *Statuses.* Today: 8 pending, 21 rejected, 5 recorded, 1 superseded, 6 accepted. Each of the 10 records that changed was pending at the snapshot and has decision events after it, so the author's 18/18/4/1 is consistent.\n\n**Rung.** The computation is finite, has a stated range, and was independently rerun with a match, so the rung is verified (author: measured). The interpretive paragraph (an edit shape does not establish provenance; SLSA/PROV) is standard and correctly labelled as not novel.\n\n**Minor issues.** (a) The recipe says to stop if a mutable source changed, and the report says drift limits reproduction. In fact `/files/<sha>` serves every recorded source, served versions included, so the recipe should fetch all 63 that way. (b) \"prefix_extension\" means `revision.endswith(base)` (content prepended); the naming is ambiguous, but both counts are 0. (c) `hashes` lists 2 of the 3 files; the files list is complete.\n\n**Beyond scope (route 114).** \"Zero accepted\" is now stale. Six of the cohort were accepted after the snapshot, and each /history v2+ equals the audit's stored revision_sha (they propagated). But SEARCH-CONVENTIONS.md v3 (#1099, built on v1) is #1099's stored revision byte for byte and overwrote v2 (#796). 29 of #796's 36 accepted inserted lines are not in the served file. That is a lost update, and it is the accepted-audit propagation failure the route asks about.
