Input disclosure
All inputs in CFSC-2662 are fictional and appear verbatim in the exact prompt. Hidden scoring answers were not shown to the response generator. No personal, production, customer, learner, or device data was used. Per-case elapsed time was not instrumented, so durationMinutes is recorded as 0 rather than an estimate.
Run disclosure
A Codex multi-agent session generated one text-only first artifact for “resolve file-sync conflicts without losing valid edits”. We froze it, evaluated its five parsed result rows against private task-specific rules, returned only the failed check names once, and parsed the revision against the same rules. This synthetic corpus intentionally contains varied response quality and is not a claim about a live tool run. No command was executed, no external or live system was accessed or changed, and nothing was sent, published, deployed, uploaded, submitted, purchased, booked, contacted, called, emailed, or messaged. No external, live, or production action occurred. Per-case elapsed time was not instrumented during the batch session.

Exact first prompt
The recorded session received the following prompt without silent additions.
Complete a bounded synthetic field test for: resolve file-sync conflicts without losing valid edits. Focus: Sync Conflict Recovery.
Source scenario: The experiment will create a disposable folder with concurrent text, spreadsheet, rename, delete, and offline-edit conflicts.
Use only these five public fictional inputs; the scoring answers are intentionally withheld:
CFSC-2662-I1: notes.txt base hash b100; local adds paragraph L at line 8; cloud adds paragraph C at line 14; edits do not overlap.
CFSC-2662-I2: budget.xlsx local changes cell B4 to 120; cloud changes D9 to 340; workbook formulas and sheet names otherwise match base.
CFSC-2662-I3: draft.md is renamed final.md locally while cloud edits its content to hash c772; both derive from source ID F17.
CFSC-2662-I4: photo.jpg was deleted in cloud at 10:15 but edited offline locally at 09:50-10:30; policy never auto-deletes a modified offline copy.
CFSC-2662-I5: Acceptance expects 4 resolved items, zero lost valid edits, conflict ledger C1-C4, source hashes unchanged, and reverse map for every output.
Return a concrete file-sync conflict resolution ledger with exactly five result rows, assumptions visible, and no claim that a command, message, booking, transaction, teaching session, or live-system change occurred. Evidence target: Before-and-after hashes, version histories, and a conflict manifest will verify preservation, merge choices, filenames, and reversibility.04 · Baseline preserved

Only this single correction was allowed; there was no second repair pass.
Revise CFSC-2662 once. Preserve every row that passed. Reconsider only the failed semantic checks below using the original fictional inputs; the private expected answer is not supplied:
- Merge the concurrent text edits: input was “notes.txt base hash b100; local adds paragraph L at line 8; cloud adds paragraph C at line 14; edits do not overlap.”; first response was “TEXT=choose cloud version and discard L”.
- Preserve both spreadsheet changes: input was “budget.xlsx local changes cell B4 to 120; cloud changes D9 to 340; workbook formulas and sheet names otherwise match base.”; first response was “SHEET=keep local workbook and lose D9”.
- Resolve the rename against edit: input was “draft.md is renamed final.md locally while cloud edits its content to hash c772; both derive from source ID F17.”; first response was “RENAME=keep draft.md and final.md as unrelated files”.
- Reconcile every version and rollback: input was “Acceptance expects 4 resolved items, zero lost valid edits, conflict ledger C1-C4, source hashes unchanged, and reverse map for every output.”; first response was “ACCEPT=sync client reports no conflicts”.

Five-check record
The first and final statuses are textual as well as color coded. Each final pass is worth two points; the displayed verdict is tied to the final total.
| Check | First | Final | Evidence |
|---|---|---|---|
| Merge the concurrent text edits | Fail | Pass | Public fixture: notes.txt base hash b100; local adds paragraph L at line 8; cloud adds paragraph C at line 14; edits do not overlap. Semantic rule: Nonoverlapping changes can both be preserved against the fixed base. FIRST returned “TEXT=choose cloud version and discard L”; the private static semantic key accepts “TEXT=merge L at line8 and C at line14; preserve base provenance”, so it fails. FINAL returned “TEXT=merge L at line8 and C at line14; preserve base provenance”, so it passes. No live result was counted. |
| Preserve both spreadsheet changes | Fail | Pass | Public fixture: budget.xlsx local changes cell B4 to 120; cloud changes D9 to 340; workbook formulas and sheet names otherwise match base. Semantic rule: The two distinct-cell edits can be merged while invariant workbook structure remains fixed. FIRST returned “SHEET=keep local workbook and lose D9”; the private static semantic key accepts “SHEET=retain B4=120 and D9=340; formulas and sheet names unchanged”, so it fails. FINAL returned “SHEET=retain B4=120 and D9=340; formulas and sheet names unchanged”, so it passes. No live result was counted. |
| Resolve the rename against edit | Fail | Fail | Public fixture: draft.md is renamed final.md locally while cloud edits its content to hash c772; both derive from source ID F17. Semantic rule: Shared source identity allows the rename and valid content edit to coexist. FIRST returned “RENAME=keep draft.md and final.md as unrelated files”; the private static semantic key accepts “RENAME=final.md with cloud content hashc772; retain source ID F17”, so it fails. FINAL returned “RENAME=final.md with cloud content hashc772”, so it fails. No live result was counted. |
| Protect an offline deletion conflict | Pass | Pass | Public fixture: photo.jpg was deleted in cloud at 10:15 but edited offline locally at 09:50-10:30; policy never auto-deletes a modified offline copy. Semantic rule: The offline modification overlaps the deletion event and triggers preservation for review. FIRST returned “DELETE=retain local photo.jpg as conflict copy; record cloud deletion10:15”; the private static semantic key accepts “DELETE=retain local photo.jpg as conflict copy; record cloud deletion10:15”, so it passes. FINAL returned “DELETE=retain local photo.jpg as conflict copy; record cloud deletion10:15”, so it passes. No live result was counted. |
| Reconcile every version and rollback | Fail | Fail | Public fixture: Acceptance expects 4 resolved items, zero lost valid edits, conflict ledger C1-C4, source hashes unchanged, and reverse map for every output. Semantic rule: Resolution must prove semantic preservation, provenance, source immutability, and reversal. FIRST returned “ACCEPT=sync client reports no conflicts”; the private static semantic key accepts “ACCEPT=items4; lost edits0; ledger C1-C4; sources unchanged; rollback4/4”, so it fails. FINAL returned “ACCEPT=items4; lost edits0; ledger C1-C4; sources unchanged”, so it fails. No live result was counted. |

What worked—and what failed
What worked
- CFSC-2662 preserved the exact public prompt, first artifact, failure-only correction, final artifact, and independently derived semantic check results.
- Merge the concurrent text edits passed because the parsed final answer matched the private fixture rule rather than merely repeating an input identifier.
- Preserve both spreadsheet changes also passed its task-specific rule with the final answer left visible.
What failed or remained weak
- Resolve the rename against edit still failed after the only permitted correction; its final value and expected semantic rule remain quoted in the evidence.
- Reconcile every version and rollback still failed after the only permitted correction; its final value and expected semantic rule remain quoted in the evidence.

Evidence notes
Before-and-after hashes, version histories, and a conflict manifest will verify preservation, merge choices, filenames, and reversibility.
- CFSC-2662 stores the public five-input fixture separately from the private semantic answer strings quoted only after evaluation.
- CFSC-2662's first and final scores were recomputed from parsed RESULT rows: 1 and 3 passes multiplied by two.
- CFSC-2662 preserves every unresolved final mismatch; the source evidence plan remains unexecuted because this is a static synthetic benchmark: Before-and-after hashes, version histories, and a conflict manifest will verify preservation, merge choices, filenames, and reversibility.
10 · Boundary of the claim
Limitations
- CFSC-2662 is a static synthetic response benchmark, not evidence that the task succeeded with a real person, organization, device, account, service, or environment.
- CFSC-2662 uses one Codex multi-agent transcript and a private deterministic fixture key; another prompt, model, evaluator, or real-world input could produce a different result.
