Evidence ledger pack audit
OSM_EVIDENCE_LEDGER_PACK_2026-08-26.zip was inspected as evidence, not as an instruction set.
| Check | Result |
|---|---|
| Archive entries | 128 entries; 123 regular files after extraction |
| Unsafe archive paths | None detected |
| Checksum verification | Every file listed in MANIFEST/SHA256SUMS.txt passed SHA-256 verification |
| Raw layer | 101 original screenshots, PDFs, and saved OSM pages according to the pack README |
| Curated layer | 16 maintained project-source Markdown files |
| Provenance rule | Raw evidence and interpreted records kept separate; planned tactics not treated as match results |
Representative raw verification performed for this handbook:
Limitations retained:
- Several early Friendly opponents and contexts remain unidentified.
- A pre-match plan remains planned evidence until the competitive result captures actual use.
- Old transfer listings and club balances are historical snapshots, not current state.
Local source audit
Ten Markdown files and three additional pasted-text references were reviewed. Hash comparison of the original Markdown set found six unique documents and four byte-for-byte duplicates.

Deterministic transfer-efficiency formula, lookup priors, and Python evaluator | Integrated as a provisional offline screening model; “auto-buy” changed to mandatory manual verification |

Magic-slider critique, controlled Friendly protocol, analyzer code, and diagnostics | Deduplicated against existing testing guidance; AI-ready reference implementation added |
5ce346…/pasted-text.txt |
Claimed disciplinary thresholds, 4-3-3 A/B structure, matchup cycle, fullback checks, and transfer warnings | Useful rules added to the supplementary claim audit; exact percentages and absolute bans downgraded pending evidence |

Four-tier validity model, confirmed-mechanics recap, speculative coefficients, and myth list | Evidence taxonomy and myth filter integrated; repeated claims deduplicated |
The local reports contained non-portable citation placeholders such as turn17view1; these were not copied as if they were usable references. The most important primary/official claims were rechecked against live public sources on 26 August 2026.

Reliability note
Official OSM sources document features and broad principles but deliberately do not expose much of the server-side match engine. Community presets remain useful as hypotheses, especially where several experienced sources converge, but they cannot prove hidden coefficients. This handbook therefore prioritizes:
Verified mechanics → starting-XI quality → coherent tactical system → opponent/venue/preparation → controlled risk tuning → repeated personal testing.
