Phase reconciliation Every claimed phase Close-SHA was resolved to a full commit object and verified for existence, parent chain, and reachability from local HEAD and origin/main. Values below are the authoritative resolved SHAs (machine-recorded in `ml/p3/governance/p3_gov2_repository_truth_audit/output/claim_reconciliation.json`). | Phase | Claimed state | Resolved commit (authoritative) | Local | origin/main | Rpt | H/O | NS present | | ------------ | ------------------------ | ----------------------------------------------- | ----- | ---------- | --- | --- | ---------- | | P3-S18 | INCONCLUSIVE | `a1283929d8b92fdac16883143f509907ee424dc2` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-S19 | VERIFIED | `84b0e56fc1e6ba2be503f462c4ef1a58e0830915` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-S20 | FROZEN weak signal | `7c9602ca4964f42f4ae8b7ac1ea14ab5e49e9176` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-S21.1 | descriptive coefs | `49f2f03f85a7a39ba0da115d98e103a98595509c` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-S21.2 | B | `da54c9b399eab92f696cbc38d4b4e5d52a764c13` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-S21.R | NO SILENT BUG | `ab7d444aa475d2a232d30d676820a7bdc407112f` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-S22 | B passed w/ limits | `6e553520e019e492da03831da07f850e4e377dbe` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-S22.1 | ADJ-1/ADJ-2 | `ef80fc31b44e6bcf90d4999bffe80b84f0df87da` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-S22.2 | ADJ-1/ADJ-2 | `a033e2705fce8b0240a3800050db14b2106c5068` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-S22.3 | C - material change | `0ee811e011c149b15d0586517bf24aa616c9e544` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-S22.4 | B VALIDATED | `e633baa96c75a2e8830628ce92a627aee4120cce` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-S23 | B weak/inconsistent | `a6a804b7ced141f099214dec5b4f705d94835e35` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-S24 | D - edge NOT shown | `8f1c80abe72a8db35a5fd1582c68e73033d0843a` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-S25 | E-UNRESOLVED | `84465a2e2462801bd906a98a4047ea4ea7568634` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-S25.1 | STARTED | `8d631ed58d1bb86d02513b295a72a9c352ddb4be` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-S25.1.R | COMPLETE | `390bd9e85c5d32d50848dc3713fd4304d9e6779b` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-S25.1 SB | A (chunks 0-10) | `6241383fad6d3405a45472b7e8c6370ee70ae025` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-S25.1C | A - chunk size verified | `0b38e96bf8d39afdb6b5ce2069d1b08b5993b619` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-S25.1D | COMPLETE (multi-chunk) | `7e7b6726cf04de85148c3005ed00dc5460da901e` | ✓ | ✓ | ✓ | folded-into-DR | ✓ | | P3-S25.1D-R | COMPLETE (A) | `7e7b6726cf04de85148c3005ed00dc5460da901e` | ✓ | ✓ | ✓ | ✓ | ✓ | | P3-GOV-1 | CLOSED (B) | `49b174eb4103dc5707c8411c1b3b6c8cec3579be` | ✓ | ✓ | ✓ | ✓ | ✓ | **Material commit conflicts: 0.** Every claimed SHA exists as a commit, is linked in the parent chain, and is reachable from `origin/main`. Interpretation note (two-commit convention): for phases whose Close-SHA is the phase's documentation tip (S18, S19, S20, S21.x, S22, S22.1, S22.2 — the doc recording the phase result), the substantive research commit is its parent. For machine-evidence phases (S22.3, S22.4, S23, S24, S25, S25.1, S25.1C, S25.1D/D-R, GOV-1) the Close-SHA is the substantive/evidence commit (research or combined documentation+research commit). No claimed SHA was found to be a bare doc-tip mislabeled as substantive, and no substantive commit was mislabeled as the repo tip. ## D. Documentation / artifact contradictions | # | Finding | Severity | |---| ------- | -------- | | D1 | `CURRENT_DECISION_GATE.md` still authorizes "CHUNK 9 ONLY / offset 113,246,416" whereas the real checkpoint is chunk 10 committed / next 11 / offset 163,578,081 | minor-doc | | D2 | `README.md` CURRENT-status block pinned at "P3-S25.1C COMPLETE / conclusion D" while `CURRENT_PROJECT_STATE.md` has advanced to "P3-S25.1 Stage-B CHUNK 10 COMPLETE" | minor-doc | | D3 | `CURRENT_PROJECT_STATE.md` states `run chunk_size = 25165824 (24 MiB)` but the authoritative checkpoint top-level `chunk_size` field is `12582912` (12 MiB, the initial-run value); per-chunk manifests show 24 MiB for chunks 9-10 only | minor-doc (canonical field record) | | D4 | `PROJECT_PHASE_INDEX.md` header "CURRENT AUTHORITATIVE phase = P3-S25.1C COMPLETE (HEAD 0b38e96b...)" is stale after chunks 9-10 and S25.1D | minor-doc | | D5 | GOV-1 handover records final SHA `983adbd9...`; GOV-1 tip commit is actually `49b174e` (the commit that wrote that record). `983adbd` is the last substantive GOV-1 classification commit. | minor-doc | None of D1-D5 contradict research/commit evidence; all are documentation/narrative staleness. ## E. P3-S25.1 current real checkpoint truth ```text run_id P3_S251_REAL_TICK_RUN_001 source_path D:\...\MQL5\Files\XAUUSD_mt5_ticks.csv source_sha256 5252ce8f5b0e7d286b71a3172c7ef9c1009c8e4b1254ac67400a803fcd85cba1 source_size 34,473,661,010 bytes (34.5 GB) status CHUNK_COMMITTED last_completed_chunk 10 current_chunk 10 next chunk 11 next byte offset 163,578,081 cumulative rows 3,661,058 cumulative M15 18,579 cumulative M30 9,966 last_timestamp 1,078,220,689 checkpoint file ml/p3/p3_s251_external_ingest/output/s251_real_checkpoint.json checkpoint sha256 47da8f020426bec67e9f7865519e900a28c286ba1d13a15bee6a8c0f5307afc7 full ingestion NOT COMPLETE (34.5 GB / 722,941,870 rows; ~163.6 MB ingested) ``` Chunk-10 manifest reconciliation: rows 563,266 -> cumulative 3,661,058; M15 2,462 -> 18,579; M30 1,317 -> 9,966; byte end 163,578,081. Exact. `CHUNK 11 NOT PROCESSED`. ## F. P3-S25.1C truth ```text SAFE_MAX_CHUNK_SIZE = 24 MiB (25165824 bytes) chunk-size invariance = PASS (12/24/48/64 MiB byte-identical; all diffs_vs_reference empty) boundary audit = PASS (boundary_audit_ok = true; 5 scenarios all equal) mutation detection = 10/10 (target_ratio 10/10, detected_ratio 10/10, all_detected true) 48/64 MiB tested = yes; NOT promoted to SAFE_MAX; SAFE_MAX stayed 24 MiB (evidence-based safe cap; invariance proven up to 64 MiB) ``` ## G.

Documentation narrative conflicts See D1-D5. All documentation-only; no historical report / machine evidence / commit conflict. ## I. Untracked / interrupted work ```text The only untracked path is ml/p3/governance/ (the P3-GOV-2 audit namespace). No CHUNK-11 or interruption-temp remnants present (previous-session untracked S25.1D artifacts were committed by HEAD 7e7b672). checkpoint before == after : 47da8f02... == 47da8f02... (TRUE) ``` ## J. Trust grading (repository provenance, T0-T5) | Phase(s) | Grade | Basis | | -------- | ----- | ----- | | P3-S18..S20, S21.x, S22, S22.1/22.2 | T3 | committed, remote-reachable, report+handover present | | P3-S22.3, P3-S22.4, P3-S23, P3-S24, P3-S25 | T4 | above + machine JSON values verified against claims | | P3-S25.1, P3-S25.1.R, P3-S25.1 Stage-B | T4 | above + real checkpoint verified (rows/M15/M30/offset) | | P3-S25.1C | T5 | report + JSON + handover + commit reconciled (invariance/10-10/boundary) | | P3-S25.1D, P3-S25.1D-R | T5 | report + recovery JSON + handover + commit reconciled (8/8, checkpoint unchanged) | | P3-GOV-1 | T4 | governance doc/self-audit JSON present, handover present; final-SHA nuance D5 | ## K. Required remediation (recommendations ONLY; nothing changed this session) 1. Update `CURRENT_DECISION_GATE.md` next-action to `CHUNK 11 ONLY @ offset 163,578,081` (or the owner decision from S25.1D-R handover: close-out of S25.1D benchmark vs continue ingestion). 2. Align `README.md` CURRENT-status block to `CURRENT_PROJECT_STATE.md` (CHUNK 10 COMPLETE). 3. Update `PROJECT_PHASE_INDEX.md` CURRENT header to actual tip and add S25.1D/D-R/GOV-1 rows. 4. Record in the S25.1 checkpoint/state docs that the top-level `chunk_size` field is the initial 12 MiB run value; effective per-chunk size lives in each chunk manifest. 5. GOV-1 handover: state that GOV-1 tip = `49b174e` (substantive classification commit `983adbd`). ## L. Final classification ```text B — MOSTLY RECONCILED WITH DOCUMENTED GAPS Core claims (phase chain, Git SHAs, handover chain, machine evidence, final-state values) are supported by and consistent with the authoritative repository and origin/main. Remaining gaps are non-critical documentation/narrative staleness (README, DECISION_GATE, PROJECT_PHASE_INDEX) and a GOV-1 final-SHA recording nuance. No research claim is contradicted by repository or artifact evidence. ``` ## Audit integrity self-check ```text checkpoint immutability : TRUE (47da8f02... before == after) reproducibility : TRUE (two semantic runs byte-identical) auditor mutation test : 10/10 disposable false claims DETECTED machine outputs : ml/p3/governance/p3_gov2_repository_truth_audit/output/*.json ``` *End of P3-GOV-2 repository truth audit.*
