+# NOT to be confused with this repo's own scripts/check_craftsmanship.py
+# (CLAUDE.md § Code Style), which independently and authoritatively enforces
+# the 300/40-line caps on Python source under mcp_server/, with a diff-scoped
+# baseline ratchet, and runs in CI on every push/PR. That gate is unaffected
+# by this file.
+#
+# Rationale (coding-standards.md §10 — written justification for a relaxed
+# threshold): §4 size limits target *source code*. The global checker's own
+# shipped example config (.craftsmanship.conf.example) already exempts .md
+# docs from the size rules by default (CRAFT_SKIP_EXT_DOCS) on exactly that
+# basis, but its doc-skip pattern is `\.md$` only — LaTeX paper sources under
+# docs/arxiv-*/main.tex are the same category (prose, not code) yet fall
+# through that pattern and get checked as if they were code.
+#
+# These files were already ~2400-2600 lines before this repo's own
+# scripts/check_craftsmanship.py gate was merged (PR #413, commit 0c2bf1d6) —

+A re-run of \texttt{BASELINE\_WITH} and the consolidation-only rows

+HOMEOSTATIC\_PLASTICITY and SCHEMA\_ENGINE (from negative to
+$+0.0017$). That re-run's output directory
+(\texttt{benchmarks/results/ablation/locomo\_v3\_post\_plasticity\_fix/})
+was never committed to this repository at any commit on any
+branch---verified via \texttt{git log --all --diff-filter=A}---so the
+claimed sign-flip cannot be checked against a per-query artifact and
+is retracted. The consolidation-only deltas reported in
+\S\ref{sec:locomo-evidence} (from the one committed artifact,
+\texttt{ef178da7}) are the only currently-verifiable figures for that
+group; whether the plasticity-shape bug muted any of them by an
+amount exceeding the $\pm 0.002$ MRR noise floor is an open question
+pending a re-run whose output directory is actually committed. The
+architectural-mismatch resolution (\S\ref{sec:locomo-evidence}) is
+unaffected: it rests entirely on the longitudinal-read-path group,
+which this bug cannot touch.
+
+The \S\ref{sec:intro} framing applies again, with a correction: verification did not
+just confirm the system; it surfaced two real bugs (cadence and
+plasticity result-shape), the first of which is fixed and validated
+at full scale, and the second of which is fixed in code but whose
+full-scale validation remains an open, undischarged commitment rather
+than a reported result.

+## Per-category provenance (added 2026-08-10, PR review follow-up on #347)
+
+**Correction (review round 2):** an earlier version of this section
+asserted the `benchmarks/results/ablation/longmemeval-s_v3/BASELINE.json`
+run had no code SHA (`manifest.repro = null`). That is true of the field
+*embedded in that JSON file* (an older per-row schema that predates the
+`manifest.repro` convention), but the **sibling** `benchmarks/results/ablation/longmemeval-s_v3/manifest.json`
+does carry one: `code_hash: 0e858e8db0f8a5dae0879fa0134113d101be19f8`,
+`dirty: false`, `started_at: 2026-05-02T22:39:22Z`. The run is real,
+dateable, and commit-anchored — the earlier claim was wrong, and the
+conclusion it supported ("provenance defect, not a regression") does not
+follow from it. Corrected below.
+
+The current committed LongMemEval-S run (`28145f0b`, `Temporal reasoning`
+MRR 0.917/R@10 97.7%, `Single-session (preference)` MRR 0.685/R@10 90.0%)
+is lower on two of six categories than the BASELINE row at `0e858e8`
+(2026-05-02/03; MRR 0.9256/R@10 98.5% and MRR 0.6678/R@10 93.3%
+respectively). A lower published figure is a regression only if the SAME
+protocol produced the higher number before a code change and the lower
+number after it — the test is whether a commit boundary between the two
+runs contains the drop, not whether the low value has since been stable.
+
+Checked against every committed, git-SHA-tracked run of the same
+`--variant s`, `with_consolidation=false` harness:
+
+| Date | Run | Temporal reasoning R@10 | Single-session (pref) R@10 |
+|---|---|---:|---:|
+| 2026-05-02/03 | `benchmarks/results/ablation/longmemeval-s_v3/BASELINE.json`, code SHA `0e858e8`, dirty=false | 98.5% | 93.3% |
+| 2026-07-03 | `benchmarks/results/harness_repro/longmemeval_full_20260703.json`, code SHA `1501428524`, dirty=**true** | 97.7% | 90.0% |
+| 2026-07-08 → 2026-08-09 | 30 runs, distinct code SHAs, all `benchmarks/results/repro/*/longmemeval-s.json` | 97.7% (every run) | 90.0% (every run) |
+
+**The test for "regression" is satisfied, not just approximated.** A
+regression is two measurements of the *same protocol*, at two commits, with
+a gap between them. That is exactly what the two endpoints are: both
+manifests were opened and compared field by field —
+
+| Field | `0e858e8` (high) | `28145f0b` (low, README's own current run) |
+|---|---|---|
+| Harness | `--variant s` (17-row driver calls `benchmarks/longmemeval/run_benchmark.py --variant s`) | same script, `n_questions=500` |
+| `n` | 500 | 500 |
+| `with_consolidation` | `false` | `false` |
+| `dirty` | `false` | `false` |
+| Date | 2026-05-02 | 2026-07-14 |
+
+Identical protocol, both clean-tree, both git-SHA-anchored. **This is an
+established degradation** on two of six LongMemEval-S categories —
+`Temporal reasoning` (MRR 0.9256→0.917 down, R@10 98.5%→97.7% down) and
+`Single-session (preference)` (R@10 93.3%→90.0% down; MRR moved the other
+way, 0.6678→0.685, so this category's regression is on R@10, not MRR) —
+not an open question about whether one exists.
+
+**What remains open is which commit caused it**, not whether a regression
+exists. The window between the two endpoints (`0e858e8` → `28145f0b`, or
+more precisely the first later git-SHA-tracked run at `1501428524`,
+2026-07-03) is **269 commits**
+(`git log --oneline 0e858e8..1501428524 | wc -l`); no committed artifact
+exists inside it. One plausible candidate by commit message alone:
+`8a5f31f3 Module #6 — DA active forgetting + decay-path correctness, with
+honest falsification (#69)` — touching exactly the mechanism
+(`ADAPTIVE_DECAY`) that `docs/benchmarks/e1-v3-per-category.md`'s
+pre-existing per-mechanism analysis already names as counterproductive on
+`Single-session (preference)`. Closing the window requires re-running
+LongMemEval-S at one or more intermediate commits (bisection), which is
+benchmark execution out of scope for this PR — the machine is carrying a
+separate multi-hour measurement.
+
+**Conclusion and consequence: this is a regression, awaiting a root-cause
+commit, not a coin flip between "regression" and "provenance."** A
+regression is fixed in code before it is published as a reference value —
+the low pair is **not** presented in `README.md` as the current LongMemEval
+per-category figure for these two categories; the two rows are withheld
+there with a pointer to this section. `docs/benchmarks/e1-v3-per-category.md`
+carries both endpoints with the same framing.
+
+## Findings and resolution
+
+- **LongMemEval:** Opus 5's review found that the first audit had incorrectly promoted the May E1 v3 ablation baseline (MRR 0.9124, R@10 98.4%) to the current headline while `README.md` carried 98.2%. The current headline is now the latest committed clean run with an explicit clean flag: MRR 0.9167, R@10 98.2%, n=500, code SHA `28145f0`. The E1 v3 values remain only inside their named historical ablation snapshot and its per-row analysis.
+- **LoCoMo (corrected, review round 2):** the previous version of this audit promoted a "post-fix" pair (MRR 0.8279, R@10 94.35%, code SHA `2f45bcb`) that has **no committed per-query artifact anywhere in this repository** — `docs/benchmarks/e1-v3-locomo-results-post-fix.md` cites `benchmarks/results/ablation/locomo_v3_post_plasticity_fix/` as its output directory, and that path does not exist at any commit on any branch (`git log --all --diff-filter=A -- 'benchmarks/results/ablation/locomo_v3_post_plasticity_fix/*'` returns nothing). Publishing that pair while disqualifying the historical 0.794/0.926 comparator for the identical defect (no committed artifact) was inconsistent. The only LoCoMo E1 v3 ablation run with a real, present, committed artifact is `benchmarks/results/ablation/locomo_v3/` — code SHA `ef178da7`, dirty=false, 2026-05-03, `BASELINE_NO_CONSOLIDATION` MRR 0.8278/R@10 94.2% — which is **before**, not after, the plasticity fix `5f737fe`. The thermodynamic paper's headline, benchmark table, 14-row ablation table, contributor narrative, cadence appendix, and both context-assembly citations now use this artifact-backed pair. The "post-fix re-run" narrative in `docs/benchmarks/e1-v3-locomo-results-post-fix.md` is not deleted (it may be correct) but is marked unverified pending a committed re-run; nothing publication-facing cites it as current until then.
+- **Historical 0.794 / 0.926 comparator:** this pair is the April 2026 clean-DB Cortex result (n=1982) first published in commit `b4057a`. Its original per-query artefact is not committed. All active citations now label it as a superseded historical comparator rather than attributing it to the current `CLAUDE.md`.
+- **BEAM:** the arXiv LaTeX headline already had the correct 0.591 retrieval-proxy MRR from the named five-conversation / 100-question protocol at code SHA `a071d89`. The standalone Popper appendix's stale 0.543 was replaced, and the thermodynamic Markdown source now matches the LaTeX paper by removing the invalid comparison against BEAM's incommensurable end-to-end 0.329 score. The later 395-question full split remains a separate protocol.
+- **Publication surfaces:** the thermodynamic and context-assembly LaTeX sources, their Markdown sources, the Popper/Shannon/Erdős appendices, the README benchmark table, and the arXiv endorsement drafts now use the current LongMemEval and LoCoMo headlines. Historical values are retained only with a named run or an explicit historical label.
+- **Noise-floor language:** the artifact-backed LoCoMo consolidation-only values (`benchmarks/results/ablation/locomo_v3/`) are all within the stated ±0.002 MRR floor. HOMEOSTATIC_PLASTICITY and SCHEMA_ENGINE end within noise of zero; the papers describe these as positive-direction observations within noise, not causal contributions outside noise — this claim does not depend on the pre-fix/post-fix question above, since both sweeps agreed on it.
+
+## Submission gate
+
+The source-level figure audit passes when:
+
+1. the stale-number grep contains no unlabeled LoCoMo headline (`0.805`, `91.5%`, `94.35%`/`0.8279`/`2f45bcb` — the unbacked pair retracted in review round 2) or current LongMemEval headline (`97.8%`, `98.4%`), and every retained occurrence is explicitly historical, belongs to a named protocol, or represents a different metric;
+2. the two LaTeX sources compile without undefined references or citations;
+3. `git diff --check` passes.
+
+**Result (superseded twice, most recently by review round 3, 2026-08-10):**
+the 2026-08-02 PASS verdict rested on a LoCoMo pair (0.8279/94.35%,
+`2f45bcb`) with no committed artifact; review round 2 caught this and the
+pair is retracted throughout this repository in favor of the artifact-backed
+pre-fix pair (0.8278/94.2%, `ef178da7`, `benchmarks/results/ablation/locomo_v3/`).
+Review round 2 also mis-framed the LongMemEval per-category finding as
+"cannot be established from committed artifacts alone" — review round 3
+corrected this: two committed, clean-tree, same-protocol runs (`0e858e8`
+and `28145f0b`) establish a real degradation on `Temporal reasoning` and
+`Single-session (preference)`; only the responsible commit (somewhere in
+the 269-commit window between them) is unlocalized. `README.md` withholds
+those two category rows rather than publishing the low values as reference
+figures. PDFs regenerated after the LoCoMo correction; `git diff --check`
+passes.

## Abstract
-External memory for large language models is dominated by *flat-importance* stores: vector indexes, BM25 corpora, and long-context buffers in which every item carries the same long-term retrieval prior. We argue this design is asymptotically broken. As the corpus grows, top-k retrieval over an undifferentiated pool degenerates into near-arbitrary tie-breaking among items with comparable surface similarity, and the discriminative information delivered to the consumer LLM approaches zero — a failure mode that compounds the position bias of long-context decoding (Liu et al., 2023). We formalise the flat-importance failure, then describe Cortex, a memory architecture that maintains a non-flat priority distribution across N by coupling four mechanisms: (i) continuously decaying *heat* on every item (Ebbinghaus, 1885), (ii) a hierarchical predictive-coding write gate (Friston, 2010), (iii) consolidation cascades that compress episodic into semantic memory (Kandel, 2001; McClelland et al., 1995), and (iv) WRRF fusion with heat as a tie-breaker. On three independent long-term-memory benchmarks, Cortex reaches LongMemEval R@10 = 98.4% (vs. 78.4% paper-best), LoCoMo R@10 = 94.2%, and BEAM Overall = 0.591 (vs. 0.329 paper-best). We discuss when flat memory remains adequate (small N, single-session contexts), the calibration cost of decay, and the per-write overhead of biological consolidation. We position the work within the broader Cortex ecosystem — paired with **cortex-beam-abstain** (a learned retrieval-abstention model for the residual cases where decay cannot prevent collapse), the **ai-architect-mcp-codebase** AST backend that gives memories code-structural anchors, and **prd-spec-generator** as the downstream read-heavy workload that justifies thermodynamic write costs.

+The +19.8 pp absolute gain on LongMemEval R@10 is the headline result against a published baseline. The BEAM-100K retrieval-proxy MRR is reported only for within-system comparison. Both benchmarks include question categories specifically designed to defeat flat retrieval — multi-session reasoning (LongMemEval), causal/temporal grounding (BEAM) — which is consistent with the §3.2 claim that the flat regime fails fastest on questions that require integrating information across the priority distribution.
**Where Cortex wins.** The largest gaps appear on temporal questions ("what did I decide first about X?"), causal-chain questions ("why did Y change?"), and multi-hop knowledge integration. These are the question categories that require traversal of the entity/causal graph and that benefit most from heat-modulated tie-breaking.
**Where the gap is smaller.** On surface-fact retrieval ("what is the value of X?") with a small corpus, flat baselines do reasonably well — there is no priority disambiguation to do because the fact is uniquely identified by similarity. Cortex's advantage on these categories is primarily from the FTS/trigram channels, not the thermodynamic ones.
-**Caveats on these numbers.** (i) We do not have head-to-head re-runs of every published baseline on our exact protocol; we report Cortex's numbers and the highest paper-reported number on each benchmark. (ii) These benchmarks are retrieval-quality benchmarks; downstream end-task accuracy with a specific LLM may differ. (iii) BEAM's Overall is a composite of seven sub-metrics — see `benchmarks/beam/` for the per-subset breakdown.

This is the load-bearing finding of §6.3.4. The §6.3.3 argument (that 13 LME-S rows were *predicted-null by construction*, not failed mechanisms) is now empirically substantiated for the longitudinal subset: when the benchmark exercises the mechanism-of-action, the mechanism shows up in the deltas.
-**Top contributors per anchor group.** In the longitudinal-read-path group, ADAPTIVE_DECAY (|ΔMRR| = 0.0163, counterproductive) and RECONSOLIDATION (ΔMRR = +0.0076, positive) dominate; the third row CO_ACTIVATION (+0.0010) is consistent-sign but at the per-row noise floor. In the consolidation-only group, all nine deltas sit within the per-row noise floor (≈ ±0.002 MRR at n = 1986 single-seed); HOMEOSTATIC_PLASTICITY (-0.0025) is the largest absolute, EMOTIONAL_DECAY (+0.0015) and TWO_STAGE_MODEL (-0.0012) follow. The honest reading of the consolidation-only group is that the consolidation pipeline as a whole contributes (the cadence fix narrative in §6.3.6 is not undone by these deltas), but no single consolidation-time mechanism dominates at LoCoMo's scale — the same calibrated-stack property §6.3.1 already documented for LME-S.

The honest reading is that no single consolidation-time mechanism dominates at LoCoMo's scale — the same calibrated-stack property §6.3.1 already documented for LME-S.
-**Limitations of the LoCoMo run.** Single-seed at n = 1986; per-row noise floor ≈ ±0.002 MRR. The plasticity result-shape contract bug fixed in commit `5f737fe` (§6.3.7 below) was discovered *during* the LoCoMo sweep and the run was launched on bytes pre-fix; the BASELINE_WITH and the nine consolidation-only rows therefore ran with a logged-WARNING (not a crash) that may have muted some consolidation deltas. The three longitudinal-read-path rows ran with consolidation off, are not affected by the plasticity bug, and constitute the empirical resolution finding above. The follow-up re-run on post-`5f737fe` bytes is reported in §6.3.4.1.
-
-#### 6.3.4.1 The plasticity-fix re-run on post-`5f737fe` bytes
-
-The §6.3.7 plasticity result-shape contract bug was fixed in commit `5f737fe`; the same 14-row two-baseline sweep was re-run at full n = 1986 on a descendant SHA (`2f45bcb`, dirty=false, finished 2026-05-04). Artefacts at `benchmarks/results/ablation/locomo_v3_post_plasticity_fix/`. The detailed writeup is `docs/benchmarks/e1-v3-locomo-results-post-fix.md`.
-
-**Headline.** `BASELINE_NO_CONSOLIDATION` reaches MRR = 0.8279, R@10 = 0.9435; `BASELINE_WITH_CONSOLIDATION` reaches MRR = 0.8265, R@10 = 0.941; ΔvsNO = +0.0014 — **identical to four decimals** to the pre-fix value. The cadence-fix anchor agreement (§6.3.6) is therefore re-validated at full n on a second independent run on bytes that include the plasticity fix. The longitudinal-read-path group is essentially unchanged between runs, as expected: those rows ran with consolidation off, so the plasticity bug had no opportunity to exercise.
-
-**Pre-vs-post-fix comparison.** The consolidation-only group has three sign-flips relative to the pre-fix sweep, two of them moving out of noise:
-
-| Mechanism | Pre-fix ΔMRR | Post-fix ΔMRR | Reading |
-|--------------------------|-------------:|--------------:|---------|
-| RECONSOLIDATION | +0.0076 | +0.0091 | Slightly stronger; same dominant-row reading |
-| ADAPTIVE_DECAY | -0.0163 | -0.0163 | Identical |
-| CO_ACTIVATION | +0.0010 | +0.0015 | Same sign, at noise floor in both runs |
-| HOMEOSTATIC_PLASTICITY | -0.0025 | **+0.0017** | **Sign flipped**; plasticity-bug-muted negative reading was an artefact of the contract bug; with clean plasticity the row contributes positively |
-| SCHEMA_ENGINE | -0.0004 | **+0.0017** | **Sign flipped** at the boundary of noise; mirrors HOMEOSTATIC_PLASTICITY |
-| SYNAPTIC_PLASTICITY | 0.0000 | -0.0003 | Within noise; explicitly clean ablation |
-| Other 6 consolidation rows | within noise | within noise | All deltas remain within ≈ ±0.002 MRR |
-
-Two rows (HOMEOSTATIC_PLASTICITY at +0.0042, SCHEMA_ENGINE at +0.0021) move from negative-or-noise pre-fix to positive-out-of-noise post-fix; this is the magnitude of contribution that was muted by the contract bug. Six other consolidation-only rows remain at the per-row noise floor in both runs. The architectural-mismatch resolution (RECONSOLIDATION ΔMRR = +0.0091, ADAPTIVE_DECAY ΔMRR = -0.0163) is **strengthened** on clean bytes — the dominant longitudinal contributions are intact and slightly larger in magnitude, as predicted in §6.3.4 (the longitudinal rows were never affected by the plasticity bug, so any movement is attributable to single-seed run-to-run variance at the noise floor; the magnitudes here move with that variance, not against the hypothesis).
-
-**The verification self-correcting.** §6.3.7 declared the plasticity-shape bug as a possible source of mute on the consolidation-only group and committed to a follow-up re-run. This subsection is that re-run. Two consolidation-only rows (HOMEOSTATIC_PLASTICITY, SCHEMA_ENGINE) recover positive contributions that were silently masked; the cadence-fix anchor agreement is re-confirmed; the load-bearing architectural-mismatch finding is re-confirmed and slightly strengthened. The verification campaign now comprises three artefact sets at full n (LME-S 17 rows + LoCoMo 14 rows pre-fix + LoCoMo 14 rows post-fix = 45 per-mechanism evidence rows on the appropriate benchmark for each mechanism's mechanism-of-action), with the only contract bug surfaced during verification re-measured on clean bytes and the result documented either way.
+**Limitations of the LoCoMo run.** Single-seed at n = 1986; per-row noise floor ≈ ±0.002 MRR. The run started before the plasticity result-shape fix `5f737fe` landed (§6.3.7), so the consolidation-only group's deltas may be slightly muted; magnitudes below the noise floor are not interpreted causally regardless. A re-run on `5f737fe`-or-later bytes with its output directory committed would let this limitation be closed with evidence rather than narrative — see §6.3.7.

The fix (commit `6c51bce`) introduces `memories.ingested_at TIMESTAMPTZ NOT NULL DEFAULT NOW()`, with an idempotent migration backfilling `ingested_at = created_at` for legacy rows, and routes the cadence gate, ACT-R lifetime computation, synaptic-tagging window, and temporal-novelty signal through `ingested_at` rather than `created_at`. Regression tests in `test_compression.py`, `test_decay_cycle.py`, and `test_pg_ingested_at.py` lock the new behaviour. The fix is independent of the LME-S evaluation reported in §6.3.1–6.3.3 (LME-S is not consolidation-dependent) but is necessary for the LoCoMo half (§6.3.4) and for any production backfill scenario where memories are ingested with historical timestamps.

The §6.3 narrative does not change as a result: the architectural-mismatch resolution holds (RECONSOLIDATION ΔMRR = +0.0091, ADAPTIVE_DECAY ΔMRR = -0.0163 on clean bytes); two consolidation-only rows (HOMEOSTATIC_PLASTICITY, SCHEMA_ENGINE) move from noise/negative to positive-out-of-noise, recovering the contribution the contract bug had silently muted; the cadence-fix anchor agreement (§6.3.6) is re-validated identically (ΔvsNO = +0.0014). We declare both the bug and the re-run rather than amend silently because the verification campaign's evidence is the load-bearing argument of §6.3, and the integrity of that argument requires disclosing every code-path artefact that touched the numbers — and remeasuring on clean bytes once the artefact is removed.
+**Correction (2026-08-10, issue #347 review round 2):** a "post-`5f737fe` re-run" was previously reported here and cited as re-confirming the architectural-mismatch finding with a described sign-flip on HOMEOSTATIC_PLASTICITY and SCHEMA_ENGINE. That re-run's output directory (`benchmarks/results/ablation/locomo_v3_post_plasticity_fix/`) was never committed to this repository — verified via `git log --all --diff-filter=A` across every branch — so the described sign-flip cannot be checked against a per-query artifact and is retracted as a paper-bearing claim. The consolidation-only group's deltas in §6.3.4 (all within the ±0.002 MRR noise floor) are the only currently-verifiable figures for that group; whether the plasticity-shape bug muted any of them by an amount exceeding the noise floor is an open question pending a re-run whose output is actually committed.
The §1 framing applies again: verification did not just confirm the system; it surfaced two real bugs (cadence and plasticity result-shape) that are now fixed.
#### 6.3.8 Caveats specific to §6.3
-- **Single-seed per run.** Each row in §6.3.1 (17 rows, LME-S, n = 500) and §6.3.4 (14 rows, LoCoMo, n = 1986, pre-fix bytes) is run once; the §6.3.4.1 LoCoMo post-fix re-run adds 14 more rows on independent bytes (`2f45bcb`, descendant of `5f737fe`). Per-question noise averages down by $\sqrt{n}$; empirical per-row noise floor is ≈ ±0.001 MRR on LME-S and ≈ ±0.002 MRR on LoCoMo. ΔMRR magnitudes below the relevant threshold are not interpretable as causal contributions; the paper-bearing claims of §6.3 are the *category-specialization pattern* (LME-S), the *empirical resolution of the architectural-mismatch hypothesis* (LoCoMo, confirmed on two runs straddling the plasticity-shape fix), and the *integrated stack lift over the published baselines on both benchmarks*, not the per-row sub-noise deltas.
+- **Single-seed per run.** Each row in §6.3.1 (17 rows, LME-S, n = 500) and the §6.3.4 LoCoMo sweep (14 rows, `ef178da7`, dirty=false, the one LoCoMo E1 v3 ablation run with a committed artifact) is run once.

- **Two benchmarks, complementary architectures.** LME-S §6.3.1 captures saturated-rerank and integrated-stack behaviour; LoCoMo §6.3.4 captures longitudinal mechanism behaviour. The two together cover the read-path / write-path / consolidation-path stack; neither alone would.
- **Calibration-conditional.** The integrated lift is reported at the Phase A/B calibrated equilibrium. Re-calibration on a different workload (e.g. an emotion-laden corpus that exercises the affect-side gates) would shift the per-mechanism contributions; §8 already notes that *the model is general; its constants are not.*

-2. **BEAM Overall = 0.543.** Same questions. Higher impact-if-wrong because the headline beats best-in-paper (0.329) by a large margin — a single-run inflation here is the most damaging citation in the campaign.
-3. **LoCoMo R@10 = 92.6% / MRR = 0.794.** Same questions. Same fix.
+1. **Historical LongMemEval R@10 = 97.8% / MRR = 0.882 (CLAUDE.md April 2026).** Provenance of that original pair remains unknown. It is superseded for current reporting by the clean run at SHA `28145f0` (R@10 98.2%, MRR 0.9167, n=500); the multi-run noise-floor experiment remains open.
+2. **Historical BEAM Overall = 0.543.** Provenance of that old headline remains unresolved. It is superseded for current reporting by the named five-conversation / 100-question retrieval-proxy run at SHA `a071d89` (MRR 0.591); do not conflate it with the later 395-question full split.
+3. **Historical LoCoMo R@10 = 92.6% / MRR = 0.794 (superseded; April 2026, n=1982).** The publication commit is `b4057a`, but the original per-query artefact is not committed. Same fix.
4. **All ablation Δs in `bench/beam/ablation_results.json`.** No σ. Cannot distinguish 1pp signal from 1pp noise.
5. **All latency claims (`<50ms`, `<100ms`, `<200ms` in CLAUDE.md tool table).** Targets, not measurements. No published p99. Required: emit p50/p99/p999 from a real workload trace.
6. **Cross-benchmark transfer claims.** Currently zero published numbers; any future claim must follow E5 protocol from day one.

**Design.**
- Factor: configuration source ∈ {LongMemEval-tuned (frozen)}. No tuning loop on LoCoMo.
-- Single arm; the comparator is the historical LoCoMo standalone-tuned score from
- CLAUDE.md (MRR=0.794). This is a one-arm pre-registered claim.
+- Single arm; the comparator is the historical April 2026 clean-DB LoCoMo
+ standalone-tuned score (MRR=0.794, n=1982), first published in commit
+ `b4057a`. This superseded value remains frozen here because changing a
+ pre-registered comparator after the fact would invalidate the protocol.
- Replications: 3 seeds (DB load order). LoCoMo is 1986 Q — high statistical power.
-- Zero-cell: prior published MRR=0.794 (read from `docs/benchmarks/` snapshot
- at protocol freeze).
+- Zero-cell: superseded historical MRR=0.794 (read from the repository snapshot
+ at protocol freeze; original per-query artefact was not committed).
- Blocking: same hardware, embedding cache, Postgres binary as E1's LoCoMo block.
**Sample size / power.** 1986 Q × 3 seeds = 5958 evaluations. Paired bootstrap on MRR.
