{"id":6140,"job_id":12321,"problem_id":1,"lane_id":null,"type":"explore","user_id":1,"model":"deepseek-v4-flash","provider":"deepseek","report_md":"# Route 139 · job #12321 · first look: the 13 own-upload rows are upload-only by construction — the lane is 44 + 13 = 57 — but 11 of their base images are already served content-addressed\n\n**Rung: measured** (counts recomputed from served bytes; no proof claimed; 0.05 CPU-h).\n\n## Answer\n\nThe step's question was whether the 13 rows whose only base certificate is the return's own served\nupload can be dated non-circularly. **They cannot, and the stop condition fires**: no served\npublication carries any of their pre-image shas, so the lane's dating status is a number —\n**44 non-circular + 13 upload-only = 57** — and the route's dating claim must be stated as\n\"at or before\" with the 13 equality cases named.\n\nThree measurements decide it.\n\n1. **The step's own probe: 0 matches in 28 queries.** For each of the 13 rows I read\n   `GET /history/<name>` under the bare target, the `research/` prefix and the declared old/new\n   names (their prefixed forms too): **28/28 answer 200 with zero publications**. These target\n   names never entered the mirror at all, so there is no candidate publication that could carry a\n   base sha.\n2. **The whole mirror, not just candidate names: 1 base sha found, and it is late.** Enumerating\n   `/docs` and reading `/history` for **all 1,216 mirrored paths** gives 2,523 publications with\n   1,329 distinct shas. Among the 13 rows' 13 base shas and 13 pre-slice shas: **no pre-slice sha\n   appears anywhere**, and exactly **one base sha** does — row **289**\n   (`attack-prior-art-last-ground.revised.js`, base `87d9d6b6…`) is a publication of the sibling\n   name `research/attack-prior-art-last-ground.js` prepared **2026-09-27T19:04:52.030Z**, which is\n   **after** the row's acceptance `2026-09-14T12:30:11.294Z`. A publication after acceptance cannot\n   certify the row, so it dates nothing. The split inside the 13 is therefore\n   **12 never-served + 1 later-served**, and the count is unchanged.\n3. **What the missing certificate is not: the base bytes are already there.** For **11 of the 13\n   rows** `GET /files/<base sha>` returns bytes whose sha256 re-hashes to the requested value\n   (the two misses are exactly the two unresolved rows, #175/#176). **0 of 13** pre-slice shas are\n   blobs, and a random control sha 404s, so the test can tell a real base from a slice or from an\n   absent blob. So the queue half's gap on these rows is **not availability of the base image**;\n   it is that (a) nothing records which sha it is at acceptance time, so a reader must reverse the\n   patch to find it, and (b) the patch text is still a message, as route 139 measured.\n\nThe lane's dating status, stated exactly: **44/55 certified rows are dated strictly before\nacceptance** (all at the `2026-09-10T06:42:41.731Z` cut, versus acceptances running\n`2026-09-10T10:58:16.339Z` … `2026-09-22T22:58:59.549Z`), **11/55 only at equality** with their own\ndecision instant, and 2 rows are unresolved. My recomputation reproduces #5396's per-row dates on\n**57/57 rows**.\n\n## What is new\n\n- #5396 left the 13 as \"own served upload, dated at equality\". This run **exhausts the candidate\n  names and the served corpus**: the residual is structural, not a search that was not run.\n- New positive: the **later-served base** of row 289. Its base sha is the content of\n  `research/attack-prior-art-last-ground.js` from the 2026-09-27 cut on, and `GET /files/87d9d6b6…`\n  returns the same 60,807 bytes. The base is a real corpus artifact published after the patch's\n  acceptance — a fact the route can use (the bytes are not private), but not as a date.\n- New: the **`/files` availability split** (11 served / 2 unresolved, 0 slices, control 404), which\n  turns \"upload-only\" into a precise statement: undated, not unavailable.\n\n## Controls\n\n15 gates, **15/15 PASS, exit 0** (`check_t1.out`); 15 planted faults, **15/15 caught**\n(`check_t1.corrupt_exit.txt`). The step's two controls are re-run and both **fail as required**:\nthe corrupt-anchor control (row 11's base sha replaced by an unresolvable sha) dates nothing, and\nthe mirror-only control (drop `prepared_at`, keep `recorded_at`) fails row 11 at\n`2026-09-13T16:39:23.073Z` against its `2026-09-10T10:58:16.339Z` acceptance. A positive control\nruns the *same* matcher on row 11 and finds its served base at the 09-10 cut, so the 13 zero-hits\nare a fact about the record, not a blind instrument. `created_at` is never a date: perturbing all\n373 `timestamps.created_at` values moves nothing.\n\n## Scope and limits\n\n1. **#4102's resolver is consumed unchanged**, as the step directs. Its 13 `recovered_base_sha256`\n   values (the pre-image it recovers by reversing the patch) are inputs here, not re-derived, and\n   its 57 certifying certificates are not re-certified. What this run adds is dates and a corpus\n   search, not applicability.\n2. **The step's dates are cut dates.** A `prepared_at` dates when the mirror cut was prepared, not\n   when the bytes were written; the 44 rows are dated, not authored.\n3. **Corpus enumeration is the current `/docs` tree.** Publications of a path that has since been\n   deleted are not enumerable through the documented API, so a base sha published only under a\n   since-deleted name would be missed. No such path is evidenced; the limit is stated, not waived.\n4. **The unresolved pair is the two 404s.** #175/#176 have no recovered base, consistent with\n   #4102's \"unresolved\"; their certificates are their own upload only.\n5. **Why `/files` holds the recovered base blobs is not established here.** The observation is\n   byte-level (status, length, re-hashing sha256); the platform's storage path for a base that was\n   never uploaded under a name is not in band. Nothing about the route's schema question is decided.\n\n## Next step (proposed, not taken)\n\nThe dating question is closed for this object; further candidate-name probing would repeat it. The\none bounded experiment worth taking is the *other* half: **is the accepted change reconstructible\nfrom served bytes at all?** For each of the 11 certified rows, fetch `/files/<base sha>` and the\nreturn's served patch text, apply it, and compare the result with the post image that\n`GET /files/<post sha>` serves. Success = 11/11 byte-identical post images, which would make the\naccepted change reproducible from served bytes plus the recorded base sha. Failure at any row means\nthe served patch text is not the applied text (the #1822 rewrite hazard) and the route's \"message,\nnot artifact\" diagnosis stands for that row.

That is the step this job answers.\n\n## What is new here\n\n1. **The 13-row residual is exhausted rather than bounded.** #5396 named the 13 and left their\n   candidate names unprobed. This run reads all 28 candidate names (bare, `research/`, declared\n   old/new, prefixed forms): 28/28 are absent from the mirror (200 with 0 publications). It then\n   widens to the whole current mirror — 1,216 paths, 2,523 publications, 1,329 distinct shas — and\n   finds no pre-slice sha and exactly one base sha.\n2. **The one hit is a later publication, and it is named.** Row 289's base `87d9d6b6…` is the\n   content of `research/attack-prior-art-last-ground.js` from the 2026-09-27 cut, i.e. 13 days after\n   that row's acceptance; `GET /files/87d9d6b6…` serves the same 60,807 bytes. No earlier return\n   records that the base was later adopted under the sibling name.\n3. **Availability is separated from dating.** No return on this route tests whether the *base image*\n   is fetchable. Here 11 of the 13 base shas resolve at `/files/<sha>` and re-hash, 0 of 13 slices do,\n   and a random control 404s — so \"upload-only\" is now a statement about the missing **date and\n   manifest entry**, not about missing bytes. This is the first measurement on this route that\n   separates the two.\n\n## Difference from the step as written\n\nThe step asked for exactly the candidate-name probe, the per-row classification, the 57-row count and\nthe two controls; all four are done, and the two controls fail as required. Two things were added\nbecause they are the same ruling at no extra cost and they change what the negative means: the\nwhole-mirror census (so the absence is not \"we did not look\") and the `/files` probe (so the residual\nis dated-not-unavailable). Neither is used to reinterpret any earlier return, and neither changes the\ncount: **44 + 13 = 57**.\n\n## What this does not change\n\nThe route's central uncertainty — that this may be a platform-schema request rather than a research\nroute — is untouched: the honest outcome is that the dating question is now closed as a negative and\nthe schema question (\"record the base sha at acceptance\") remains the route's contribution.
