PROVENANCE — Lazy_private

Generated by experiments/build_provenance.py on 2026-10-21. Every figure is read from an artefact on disk; none is retyped. Tags: battery_v2.0 (the test battery as used), validation_v2.0 (the eight references, licence tables and verdict). The registration cites validation_v2.0 by hash; the phase battery will be a new tag.

Freeze scope

The eight references below. Nothing further is recorded before posting — the Qwen arm, the read-site fix and the phase battery all follow it.

• cells 90, cores per construct 8
• Seeding defect, recorded as caught. Seeds were derived with abs(hash((twin, core_id, cell_key))) % 2**31. Python salts hash() for strings per process, so every build produced a different battery and the seeds recorded here could never regenerate it — verified by staging a rebuild: 152 of 152 sets differed, none identical. profilebattery/generate/seeds.py replaces it with a keyed blake2b digest for future builds, with a cross-process regression test. This battery cannot be regenerated; its provenance is the per-set content hash below. The phase battery is generated under the fixed seeding, with each twin drawing its own cores.
• Twins share all eight cores, contrary to the spec's "each twin draws its own eight from a space of ≥24". Twin disagreement therefore carries no core-sampling variance: the twin unit is a draw-and-yardstick unit, and every figure quoted in twin units inherits that.
• access-form labels record the realised level, not the nominal one (self_attribute degrades outside a method); relabelled in place, each set verified text-identical.

Per-set content hashes (212 sets)

battery/CONTENT_HASHES.json holds a sha256 over each set's prompt texts in order. A set is re-recorded only if its content hash changed. run_sweep.py stamps prompt_sha256 into every record MANIFEST and refuses to run without the hash file. Manifest of hashes: 9bb00f2b78bece7c

Record

• primary hook: model.layers.{i}.mlp.down_proj forward pre-hook, args[0] — the gated product act(W_gate·x) ⊙ (W_up·x), 6,144 wide. Verified against recomputation at max abs difference 0.0.
• secondary: .mlp output (m_k, 2,240 — the v1 basis); residual stream at the same positions.
• sites: construct token (primary), span end, last token. C read at every position, labelled by (relative-position band × token class), 20 cells.
• dtype: per-prompt fp16, accumulation fp32, model bfloat16 on MPS.

fp16 overflow is zero at every reference, layer and site. No layer needed the fp32 fallback.

The untrained reference's weights do not regenerate. It is not a checkpoint but a null -- the architecture instantiated from the pretrain_iter_0008000 config under torch.manual_seed(20260920) (MANIFEST.json: untrained_seed), recorded on cuda in bfloat16. Re-instantiating it under the same seed on torch 2.14.0 / transformers 5.17.0 gives different weights: the re-run reproduces a trained checkpoint's recorded accumulators to cosine 0.999997 and the untrained one to cosine 0.004 -- orthogonal. Module initialisation draws a different number of values across library versions, so the seed alone does not pin the weights. The torch, transformers and Python versions of the recording run were not stored -- no manifest, lockfile or environment record in the repository carries them -- so the untrained reference cannot be re-recorded, and any pass needing new statistics from it is limited to what is already in the record. Future runs should store the interpreter and library versions beside dtype and device.

The local record/ tree at the eight S1 references is a stale S1-era recording and is kept, untouched, behind a guard (A50; the decision of 19 Oct). It carries three read sites, 25 B cores, 51,840 summed positions and no hs| scope keys, where the dataset's files at the same references carry one site, 21 B cores, 17,280 positions and 4,800 hs| keys; RecordStore.path() prefers the local copy, so any pass that reads accumulators would silently get the old recording at those eight references and the new one everywhere else — which is how A48 came to record a C0.5 departure that half exists. Every accumulator and yardstick read in the Paper-1 code goes through experiments/paper1.py:dataset_record(), which reads the dataset and ignores the local copy.

Storage rule (DECIDED 6): per-prompt arrays at pretrain_iter_0003000 and the untrained reference; per-core, per-cell accumulators everywhere. The accumulator route reproduces the per-prompt profile to cosine 1.000000, max|diff| 0.0 — asserted by test_accumulator_route_equals_the_per_prompt_route.

Profiles

• yardstick: 24 layers × 20 cells, rebuilt at every checkpoint
• ε (smooth floor) = 0.01, grid {0.003, 0.01, 0.03}. ε does no work: worst displacement across the grid is 0.0008 twin units, three orders below twin disagreement.
• reported SE is the between-core spread of core means / √cores (Profile.se); the per-prompt SE is kept alongside as se_prompt.

Checks 2, 3, 7a and 7b require per-prompt arrays and are named NOT RUN with that reason at the accumulator-only references. Check 5 (Qwen2.5-Coder) is NOT RUN and deferred past the freeze by decision, not by failure.

Licensed n — a decision, with the rule that produced it

120 per set for the deep tier, 60 for shallow.

Rule: the smallest grid n at which the raw cosine of the subsample profile to the full-set profile reaches 0.99 for every construct in the tier, read at pretrain_iter_0003000. Measured on the grid {8, 24, 56, 120, 176}: 0/30 constructs at n=8, 13/30 at 24, 25/30 at 56, 30/30 at 120 with the minimum 0.9904 (Assign).

Two things this rule is not, both recorded so the choice is reviewable:

1. It is not stated on the disattenuated cosine. That statistic is saturated here — 133 of 150 grid cells sit at or above 0.9999, and 22 of 30 constructs are already there at n=8 — so a 0.999 criterion on it would license n=8 for most of the tier and yields 120 only because FunctionDef and If are the last to reach the ceiling. The number would be set by where the cap bites rather than by convergence.
2. It is not report rule 9.2 as originally written, "within twin noise of the full set". Twin cosine varies 0.811–0.998 by construct for reasons unrelated to sample size, so 9.2 licenses n=8 for Attribute (twin cosine 0.832) and n=176 for For (0.998). Rule 9.2 is superseded; the report and method handout carry the replacement.

The shallow tier's 60 is a declared relaxation, not this rule applied to a different tier. It is not a grid point, and at the nearest one (n=56) five of thirty constructs fall below 0.99, Assign lowest at 0.9791. It is a budget decision and is recorded as one.

The untrained reference cannot license n. Its raw cosine at n=120 is 0.618 median (range 0.575–0.806): a random-feature regime with no structure to converge to.

Interval calibration

Coverage is bimodal and stably so, against a nominal 0.95. At the three trained checkpoints the nine verdict constructs run 0.848–0.872 and the other twenty-one 0.990–0.993; FunctionDef needs ×2.03. A single factor is wrong in both directions. Per-construct factors are published in validation/calibration/COVERAGE_FACTORS.json and never applied silently.

The cause is the yardstick's own estimation error, not core clustering: holding the prompt data fixed and swapping only the twin's yardstick moves the profile 0.474 against a full twin gap of 0.940 — a quarter of the twin variance, invisible to any within-twin SE.

Go/no-go verdict

PASS — 9 of 9, read at pretrain_iter_0003000, two-thirds bar. Verdict constructs are the keyword-token constructs that also pass the read-site acceptance rule (overlap ≥0.80, minimum over twins): Assert, Delete, For, FunctionDef, If, ImportFrom, Pass, While, With.

Excluded by the read-site rule: BoolOp 0.515, GeneratorExp 0.597, IfExp 0.613, ListComp 0.569, Return 0.514, UnaryOp 0.25.

Turnover, for G4: top-5% unit-set Jaccard rises 0.176 → 0.396 across six steps against a twin ceiling of 0.595 (pilot-era: the median over the 30 pilot constructs at layer 22; the pilot recording, not the phase record — A52), and the last three steps span 21B tokens each against the first two's 4.19B while turning over less. A date criterion of the form "the set stops turning over" must be stated as a fraction of that ceiling; against an absolute threshold near 1 it cannot fire.

Known limitations carried into the freeze

1. The v1 bridge is not derived. v1's mask rule is a per-prompt consistency criterion and the record keeps per-prompt vectors for one site and one basis only, so v1's "72% of circuits wired by 8.4B" has not been re-derived here.
2. The nine verdict constructs are 55–73% length-flagged against 0.2% elsewhere. Only 2.3% of the concept profile lies along the length axis at the median (max 19.7%) and the top-5% set is not enriched for length-sensitive units (0.93×), so the concept direction is nearly orthogonal to the length direction — but a claim about which units carry these constructs is not licensed.
3. The ν-sensitivity alternative arm has n=60, reliability 0.187, so its disattenuated cosine goes over unity and is reported as raw distance.
4. Checks 5 and, at four references, 2/3/7a/7b are NOT RUN, each with its reason in the licence table.

The pilot recording at the phase recording's path (A52, A53)

Reserved for the Settle chat. The register entries are A52 and A53 in 8-Settle/2609-30Sep_DEVIATIONS-CC.md: the 2x2 that localises the damage, the thirteen affected constructs, the seven references, the figures that moved (92 -> 90 dated, 145 -> 148 falling, P7 91/92 -> 90/90), and the verdict table over every reader that preferred a local tree. The exclusion list the repo build enforces is experiments/repo_manifest.py; it fails the build rather than warning.
