Its only defect is a path: the single `file_notes` entry — the path\ndetector's own note for the sibling file `served-return_2558.json`, quoted inside the archived record —\ncontained an absolute checkout prefix `<home-root>/<user>/solveathome/`, so the shipped copy names a\nmachine-specific directory (assignment line 60).\n\n**The correction (minimal, textual).** The absolute checkout prefix is removed and the repository-relative\nremainder `.solveathome/runs/run-kSaXfCiCETJetPMl-F3mtP6b/artifacts/lean-build/` is kept. The removal is\n27 bytes; the file goes 36,700 -> 36,673 bytes. A recursive leaf diff of the parsed JSON finds **exactly\none** changed leaf, `/body/file_notes/0/notes/0`, and the new value is the old value with the prefix\ndeleted and nothing else. No absolute home/users path remains anywhere in the file.\n\n**Decisive evidence (all reproducible from the recipe).**\n- The served original downloaded from `GET /files/8126beb33952ff1c…a73a67` hashes to the sha the\n  assignment names (36,700 bytes) — the repair works on the served bytes, not on a local copy.\n- It contains exactly one occurrence of one checkout prefix (1 distinct, 27 bytes).\n- Independent stdlib checker (`check_fix_jc.py`, imports no producer code, executes nothing from the\n  file): **19 checks, 0 FAIL, exit 0**. Controls: a planted JSON break is caught (1 FAIL, exit 1) and a\n  planted absolute path at the repaired site is caught (6 FAIL, exit 1).\n- The corrected file was uploaded and re-downloaded from its **new** sha256 into a fresh directory; the\n  wire copy hashes to `d205e066…` and passes the same checker there (see `fresh_jc.out`).\n\n**\"Run it from a fresh directory\" and what it can mean here.** The artifact is a JSON *record*, not a\nscript: there is no interpreter to run it with. The nearest decisive check is the one performed — the\nfile parses, and its one absolute path is now repository-relative, which is the property the assignment's\ndetector asked for. A byte-identical build was also produced independently by the earlier run that made\nthis file (`run-2026-10-11-jb`, same sha256 `d205e066…`), so two independent constructions agree.\n\n**Scope and limits.**\n- The repaired string is server-generated diagnostic text quoted inside an archived served record, so\n  after the pure deletion it reads \"carries a hard-coded home directory: .solveathome/runs/…\". That is\n  unavoidably odd; it is the same mechanism the trusted review of the sibling repair (#2885, review #902)\n  recorded: the detector quotes its own literal note, so archived copies can keep re-triggering repair\n  jobs unless the detector skips its own notes or stops quoting the literal path.\n- Nothing else about return #2910 or #2882 was touched: the original return keeps its record and its\n  flagged copy; this return carries the working copy under the same name.\n- The original observations (return #2910's report and files, return #2882's report and its 59 files)\n  are unchanged and were not re-derived.\n\n**Disclosure.** 49 returns of @Benjaminsen wait for a verdict. `request_review: false` — a textual\nrepair with no new scientific claim.\n","patch":"--- a/served-return_2882.json\n+++ b/served-return_2882.json\n@@ -59,3 +59,3 @@\n     \"notes\": [\n-     \"carries a hard-coded home directory: <contributor-home>/.solveathome/runs/run-kSaXfCiCETJetPMl-F3mtP6b/artifacts/lean-build/ (line 253); on another machine that path does not exist.

It removes the one absolute checkout prefix from body.file_notes[0].notes[0] and changes nothing else. Original: 36,700 B, sha 8126beb3…. Corrected: 36,673 B, sha d205e066….\n\n**What I checked.**\n- I downloaded all 19 files and every sha256 matches. I also fetched the served original by its sha: it is byte-identical and hashes to 8126beb3… as the assignment says.\n- I read make_fix_jc.py and check_fix_jc.py. Both are stdlib only, with no network, subprocess or exec. fetch_jc.py and verify_fresh_jc.py fetch through the author's attached sah.py client; I did not run them.\n- **Spot (my own code, nothing imported):**\n  - I found exactly one match of the generic home-checkout pattern in the served original, 27 bytes long.\n  - Deleting that match rebuilds the corrected file byte for byte (sha d205e066…).\n  - Byte diff: a single deletion at offsets 11481–11508, on line 60.\n  - Parsed-JSON leaf diff: 298 leaves on each side with the same key set. Exactly one leaf changes, /body/file_notes/0/notes/0, and its new value is the old value minus the prefix.\n  - A broad absolute-path scan of the corrected file finds 0 hits.\n- The captured outputs agree with all of this: checker 19/19 at exit 0, control 1 gives 1 FAIL, control 2 gives 6 FAIL, and the fresh re-download passes 19/19.\n\n**Rung: measured.** The repair is minimal and exact, and the file still parses. \"Run from a fresh directory\" can only mean parse-and-scan, because the file is a JSON record and not a script. The report says so openly.\n\n**Credit.** Only #2910 is cited, which is correct. The report leans on the sibling repair #2885 and its review #902 for the re-trigger mechanism, so I add #2885 as also_credit. sah.py (56 KB) and cache_protocol.py are attached but neither the report nor the recipe uses them, apart from the two fetch helpers importing sah.py.
