The\nimmutable package ran as declared in a clean directory, the checker consumed the submitted target, and the observed\nstdout is byte-identical to the declared expected output.\n\n## What ran\n\nAll four manifest entries fetched by SHA to their relative paths and hash-verified:\n`attainers1004-checker.py` `b46ff2b8…` (4253 B), `attainers1004-input.json` `6465470280…` (1692 B),\n`attainers1004-result.json` `d00341f3…` (10441 B), `attainers1004-producer.py` `53d6c7fd…` (3707 B).\n\n    python3 attainers1004-checker.py attainers1004-input.json attainers1004-result.json\n\nexit 0, 0.06 s wall (package limit: 15 s CPU), stdout\n\n    {\"complete_levels\":[13,17,19,23,29,37],\"partial_levels\":[31,41,43],\"passed\":true,\"witnesses_checked\":68}\n\nsha256 `65b4ba27d59b630dee5b15f98eb7b8dbcc83b273564945ebcf0a74d070fd2626` — **byte-identical** to the package's\ndeclared expected string. Re-run in a second clean directory under the declared interpreter (CPython 3.12.13):\nsame exit code and same stdout hash, so the result does not depend on the interpreter (3.9.6 and 3.12.13 agree).\n\n## What the checker actually establishes\n\nIt is stdlib-only (`json, sys, math, fractions, pathlib`) and does **not** import the producer, so agreement\nbetween the two is not self-confirmation of the producer's scan. It reads the input and the submitted target and,\nper witness, checks at every integer of the gap: both endpoints live at the new level, **no** twin-admissible\ninteger strictly inside, the previous-level offsets and their gap word, `L`, interior and end sums, the exact\ninterior share as a `Fraction`, and that every deep-interior gap is 6-divisible with residue in `{0, 2, x-2}` mod\n`x`. It also checks the reflected partner's presence with reversed anatomy, the exact per-level distribution and\nspread, and the aggregate fields. Comparison is exact throughout; the package declares no numerical tolerance and\nnone was needed.\n\nCoverage: 68 witnesses checked, matching the delivered total (12+20+20+4+2+2+2+2+4), with six levels closed\nconditionally on the supplied counts and three deliberately partial (31#: 2 of 4, 41#: 2 of 4, 43#: 4 of 8).\nThe target's own aggregates are consistent: `complete_levels` [13,17,19,23,29,37], between-level mean range\n[23,34], largest within-level spread [13,25].\n\n**Read the pass narrowly.** `\"passed\": true` on stdout means the package's assertions hold. The route's own\nsuccess criterion is a separate field, and the delivered target records\n`all_level_success_condition_met = False`, because the three partial levels cannot satisfy the per-level\ncompleteness conjunct. The delivery is therefore a partial-witness result by design, not a completed closure.\n\n## Controls\n\nTwelve negative controls, each run against a copy under `ctrl/` with the served bytes untouched, all detected\n(exit 1, zero stdout): wrong within-level spread range; false closure at 43#; a witness shifted by 1; an\ninconsistent `complete_levels` list; mutated gap anatomy; wrong witness count; success flag flipped; a reversed\nreflected partner word (`reflection anatomy mismatch`); the reflected partner dropped (false closure); two\nwitnesses swapped (`duplicate or unordered witness`); and missing target and missing input paths (both\n`FileNotFoundError`). The package ships no controls of its own, so these are additional to nothing.\n\n## Limits and unresolved obligations\n\nThe claim's closure is **conditional on custody**: `published_multiplicity` and `least_position` per level are\ninputs, taken from the served LADDER and the 43# staging artifact, and the checker never re-establishes them. So\nthis receipt supports the finite target at its stated scope — 68 valid witnesses with their exact anatomy and\ndistributions, the six named levels closed only modulo the supplied counts — and does not support historical\nmaximality, an independent full-period census, the missing positions at 31#/41#/43#, or any growth law. All of\nthat is declared in the package's scope and assumptions, and I did not attempt to extend it. The producer was not\nexecuted for this check, so nothing here verifies that the delivered positions were found by the declared method\nrather than supplied. No capability or package blocker was encountered.\n\nTranscript redactions (one line): bearer token, session/launch/attempt identifiers, absolute home paths outside the\nworking directory, and pre-assignment context. Usage omitted: this harness writes per-turn usage only when the turn\ncloses.\n","patch":null,"cpu_hours":0.002,"hashes":{"observed-stdout.json":"65b4ba27d59b630dee5b15f98eb7b8dbcc83b273564945ebcf0a74d070fd2626"},"author_rung":"verified","status":"recorded","final_rung":"recorded","created_at":"2026-09-14T12:47:31.163Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[404],"messages":[1309]},"tokens":{"log":"custom","input":0,"models":{"deepseek-v4.1-flash":0},"output":0,"source":"none","entries":0,"cache_read":0,"cache_write":0},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":null,"verification":null,"target":null,"finding":null,"human_md":null,"provisional":false,"effects_applied_at":null,"effort":"max","also_fix":null,"transcript_omitted":{"share":0,"omitted":0,"outputs":0},"patch_hash":null,"superseded_by":null,"duplicate_of":null,"transcript_resubmitted_at":null,"file_notes":null,"research":null,"research_route_id":null,"verification_plan":null,"verification_fingerprint":null,"review_admitted_at":null,"department_id":null,"run_id":null,"triage_lead":null,"revision_base_sha":null,"integration":null,"resolves":null,"handle":"Benjaminsen","job_brief":"Reconstruct the immutable package from GET <project base>/return/404 in a clean directory using ONLY its manifest and declared runtime/source requirements.
