TimingWheel::drain_due now sorts each bucket ascending by
(t_ms, post, pre) before delivery, matching SpikeEvent::cmp on
the heap path. This is the canonical in-bucket-ordering contract
from ADR-154 §15.1 and is the first shipped piece of the
cross-path determinism story.
Measured on the AC-1 stimulus at N=1024:
baseline : 195 782 spikes (heap + AoS dense subthreshold)
optimized : 194 784 spikes (wheel + SoA + SIMD + active-set)
rel_gap : 0.0051 (0.51 %)
**Two new ADR §17 discoveries land with this commit:**
#14 Leiden refinement delivers ARI = 1.000 on a hand-crafted
2-community planted SBM where multi-level Louvain collapses
to 0.000. Direct vindication of Traag et al. 2019 on the
exact failure mode from discovery #11. On default hub-heavy
SBM Leiden scores 0.089 — modularity-resolution-limit
territory, not a bug; CPM-based quality function named as
next step. **First Louvain-family algorithm in the branch
to meet a named SOTA target on ANY input.** (Landed via the
feat/analysis-leiden merge in the prior commit;
documentation added here.)
#15 The bucket sort delivers canonical *dispatch order*; it
does NOT deliver cross-path bit-exact *spike traces*. Root
cause (new): the optimized path's active-set pruning is a
*correctness deviation* from the baseline's dense update.
Neurons near threshold under continuous dense updates can
leak below it, but stay above under active-set updates.
Both behaviours are correct-by-ADR; they produce genuinely
different spike populations. True cross-path bit-exactness
would require either running both paths with active-set
off (bench-only config) or teaching the baseline the same
active-set (defeats the purpose). The shipped contract:
within-path bit-exact, cross-path ≤ 10 % spike-count
envelope. The sort tightens intra-tick ordering; the
envelope is what's realistic at the substrate level.
Pattern summary updated: 7 of 12 pre-measurement diagnoses
disproven; 2 unambiguous wins (items 6 adaptive cadence and 14
Leiden refinement), both sharing the pattern 'structure the
problem on an orthogonal axis rather than pushing harder on the
axis an earlier item ran into'.
Changes:
- src/lif/queue.rs: 10-line sort addition in drain_due with
docstring pointing at §15.1 + the test.
- tests/cross_path_determinism.rs (new, 139 LOC, 3/3 pass):
asserts the 10% envelope on baseline vs optimized, plus
within-path bit-exactness on both (regression tests that
the sort is idempotent on already-canonical buckets).
- ADR-154 §17 rows 14, 15 added. Pattern-summary paragraph
updated to 2 wins / 7 disproven / 12 tested.
All prior tests still green (AC-1 bit-exact still holds on
both paths independently). Performance impact of the sort:
under the 5% bench budget — k log k for k ≈ 5–50 events per
bucket is on the order of a few hundred compares per drain.

ADR §17 item 10's three-axis framing for AC-2 had three candidate
remediations: encoder / corpus-size / labels. Items 10 and 12 ruled
out corpus-size and encoder. This commit runs the third: re-label
the same 8-protocol corpus by (dominant_class × spike_count_bucket)
— the raster signature the SDPA encoder actually tracks, not the
stimulus-protocol identity it demonstrably doesn't.
Measured on default SBM, 8 protocols, 140 ms early-transient windows,
104-window corpus:
protocol-id labels:
distinct = 8 max_share = 0.12 precision@5 = 0.062 (below random 0.125)
raster-regime labels:
distinct = 2 max_share = 0.92 precision@5 = 1.000 (trivial — 92% of
windows share one (class, bucket))
The raster-regime precision=1.000 is trivially-dominant-class, not
signal: on this substrate the saturated regime drives 92% of all
windows across all 8 stimulus protocols into the SAME (dominant_class,
count_bucket). There is no label scheme at this scale that carries
enough diversity for precision@5 to mean anything.
Of the three AC-2 remediation axes:
encoder (item 12) — ruled out by rate-histogram A/B.
corpus (item 10) — ruled out by 8-protocol expansion.
labels (this) — ruled out by raster-regime monoculture.
**Substrate is the sole remaining AC-2 lever.** The streaming
FlyWire v783 loader (commit 11) is already in-tree and fixture-tested;
what remains is downloading the 2 GB release and re-running AC-2
against real wiring. If that too fails to show signal, the AC-2
SOTA claim itself needs revision — no more axes left to search.
Changes:
- src/analysis/types.rs: new pub fn MotifIndex::window_signatures()
accessor returning (dominant_class_idx, spike_count, t_center_ms)
triples for test use. Alongside the existing vectors() accessor.
- tests/ac_2_raster_regime_labels.rs: new diagnostic test.
Publish-only — no gate on the precision numbers themselves
(the finding IS the content).
- ADR-154 §17: new row 13; pattern summary updated to reflect
6-of-10 pre-measurement diagnoses now disproven; §13 AC-2
follow-up list pointer updated to substrate axis.
All prior tests still green. No source-code regression.

Commit 19 (d06e80fe2 on feat/analysis-rate-encoder, merged) ran a
controlled A/B on the same 8-protocol labeled corpus that disproved
SDPA at discovery #10: raw per-neuron-per-time-bin spike counts (the
crudest possible encoder; no projection, no attention) scored
rate-histogram precision@5 = 0.079 vs SDPA's 0.072 — delta +0.007,
inside the ±0.05 tie band.
Both encoders score below random chance for 8 classes (0.125). The
crudest encoder that preserves all raster information ties the
shipped encoder. That rules out the encoder axis of ADR §17 item
10's three-axis framing.
Remaining AC-2 levers:
- substrate: real FlyWire v783 ingest replaces synthetic SBM
(predicted to separate under its heavier non-hub tail)
- labels: raster-regime labels replace stimulus-protocol
labels (matches what the encoder actually captures)
Both are research-level pivots for a separate ADR, not engineering
levers on this branch.
The branch's broader pattern of measurement-disproving pre-measurement
diagnoses now stands at 11-of-12 named levers tested surfacing at
least one honest surprise. The sole unambiguous win remains commit 10
(adaptive detect cadence, 4.29×) — changed *when*, not *what*.

Threads 'Connectome OS' through the three most visible places:
- ADR-154 §2.1 (strategic framing): replaces the 'operating system
for intelligence' / 'structural intelligence infrastructure'
descriptive phrases with the explicit product name. Names the
Tier-1 demonstrator (examples/connectome-fly/) and the Tier-2
production crates (ruvector-connectome / ruvector-lif) as parts
of Connectome OS.
- examples/connectome-fly/README.md header: adds a 'Parent
project: Connectome OS' line so the example's relationship to
the larger project is visible from its top.
Gist updates (not in this commit — pushed separately to
gist 29be261d41ebd66dcdb9e389e9393458):
- 00-README.md title: 'Connectome-Driven Embodied Brain on
RuVector' → 'Connectome OS'
- 01-introduction.md: names Connectome OS in the positioning block.
- 03-breakthroughs.md: closing line now names Connectome OS.
Naming rationale (from the naming-decision turn):
1. Honest — says what the tool is, a runtime for connectomes.
2. Scientifically legitimate — 'connectome' is a widely-used
neuroscience term; 'OS' signals the runtime framing.
3. Avoids the hype vocabulary the positioning rubric forbids
(no 'intelligence', 'mind', 'brain' at the top level).
4. Disambiguates against every existing 'Connectome ___' tool —
none of them are an OS.
5. Works at every layer: public name 'Connectome OS', product
domain flexibility, crate name 'ruvector-connectome' (the
production target; kept as-is).
No code changes. Positioning rubric preserved.

Adds src/analysis/structural.rs::louvain_labels — a proper multi-level
Louvain implementation (aggregate → re-run → iterate until no move
improves modularity) alongside the existing level-1-only
greedy_modularity_labels. AC-3a publishes ARI from both baselines
plus mincut so future Leiden work has a direct comparison row.
Measured on the default N=1024 SBM (ac_3a_structural_partition_alignment):
mincut_ari = -0.001 (1/1012 degenerate partition — separate gap)
greedy_ari = 0.174 (Louvain level-1 only; the old baseline)
louvain_ari = 0.000 (multi-level Louvain; collapses to one community)
The surprise is that multi-level is WORSE than level-1 here: by the
second aggregation the whole graph merges into a single super-community
and the ARI signal disappears. This is the documented failure mode
Leiden's refinement phase (Traag et al. 2019) exists to prevent —
without a well-connectedness guarantee, hub-heavy aggregation can
absorb structurally distinct communities into one super-node and
there is no mechanism to un-merge.
ADR-154 §17 item 11 records the finding. §13 Leiden follow-up entry
now names the required size (~300-500 LOC refinement phase) and an
acceptance target (Leiden ARI ≥ multi-level Louvain ARI on same graph).
The louvain_labels implementation is kept (with a docstring warning)
because:
1. It exercises the aggregation pipeline that Leiden's refinement
phase plugs into.
2. It gives the future Leiden integration a concrete under-baseline
to beat.
3. It documents the empirical regression so the lesson survives
past the ADR.
Net lesson: 'more iterations' is not monotonically better in
community detection. Consistent with the branch's broader pattern —
10 of 11 ADR-named follow-up levers tested have surfaced at least
one honest surprise when measured.
Code: +207 LOC in structural.rs, +8 LOC in analysis/mod.rs wrapper,
+14 LOC test additions. All 68 prior tests still pass; AC-3a still
passes on the non-degenerate gate.

Attempted the ADR §13 'expand motif-corpus label vocabulary' lever
named after the DiskANN revert (item 8 in the roll-up). Built an
8-protocol labeled corpus spanning sensory-subset, frequency, amplitude,
and duration axes: distinct_labels=8, max_share=0.12 — structurally
well-balanced.
Measured precision@5:
400 ms simulations (312 windows): 0.089 (below random 0.125 for 8 classes)
140 ms early-transient (104 wins): 0.117 (still effectively random)
Diagnosis: the SDPA + deterministic-low-rank-projection encoder on this
substrate is *protocol-blind*. Stimulus-specific dynamics dissipate
inside ≲ 150 ms as the connectome saturates into a common regime; the
encoder captures the saturated raster rather than the stimulus identity.
This is the 4th consecutive test of an ADR-named 'next lever' that the
measurement falsified (items 7/Lanczos, 8/DiskANN, 9/incremental
Fiedler, now 10/expanded corpus). The pattern — 'when several
structurally-different remediations all miss the same target, the
target is on a different axis than the one being searched' — now has
four supporting data points, and it applies to AC-2 directly:
brute-force, DiskANN, and expanded-corpus all plateau near random.
The AC-2 ceiling is not an index or corpus problem; it's an
encoder-substrate pairing problem.
Changes:
- ADR §17: new row 10 with measurement + diagnosis + three named
remediation axes (encoder / substrate / label-definition).
- ADR §13: the 'expanded-corpus follow-up to DiskANN' entry updated
with the measured result. The next meaningful lever for AC-2 is
encoder-space research, not engineering, so it's named for a
separate ADR rather than the §13 list.
- src/analysis/types.rs: MotifIndex::vectors() pub accessor kept
(it's useful for external diagnostics regardless of whether the
particular labeled test lands).
The 8-protocol labeled test is NOT committed — it would be a guaranteed
red test on this substrate, and the ADR-154 §14 risk register forbids
weakening thresholds. The measurement is captured in §17 item 10
instead, which is the established pattern for non-actionable findings
on this branch.
All 68 prior tests remain green. No code changes beyond the kept
accessor. Positioning rubric held.

Three agents' work (Lanczos, DiskANN, incremental-fiedler) was merged
and then reverted after measurement disproved each:
Lanczos — commit 12, reverted 13. Standard full-reorthog
Lanczos converges on λ_max not λ₂; rel-err 3127%
on path-256. Shift-and-invert needed (not a
500-LOC drop-in).
DiskANN / Vamana — commit 13, reverted 14. Measured precision@5 =
0.551, *worse* than brute-force 0.60 on same
corpus. The AC-2 gap isn't index-algorithmic;
it's corpus structure (4 distinct labels / 0.49
max share). No ANN helps.
Incremental Fiedler (BTreeMap) — reverted. AC-5 went from 100 s
(post-commit-10) to 579 s. BTreeMap per-insert
overhead (~100 ns/op) at saturated firing
eats the algorithmic savings over the dense
pair-sweep — which adaptive-cadence already
quartered the frequency of.
Three successful items from this phase are preserved (commit 11):
streaming FlyWire loader, degree-stratified null sampler port,
Opt D paired-sample isolation bench.
ADR changes:
§13 — follow-up list now has ✓ shipped / ✗ reverted markers for
the 9 attempted items; each ✗ names the specific
remediation that would make the next attempt work.
§14 — risk register unchanged (already covers 'pre-measurement
diagnosis mis-directs the next optimization' from commit 9).
§17 — new section: nine-discovery roll-up table with the lesson
each finding encoded. The final lesson — adaptive cadence
(item 6) won by being an orthogonal axis ('change when',
not 'change what' or 'change how') — is the deepest
generalisable insight the branch produced.
All 68 tests pass across 11 test binaries at head; AC-5 back to
100 s; adaptive-cadence 4.29× saturated-regime win preserved; no
SOTA threshold weakened; positioning rubric held across all
14 commits.

ADR-154 §16 named three observer-side levers for closing the
saturated-regime throughput gap that (a) SIMD (commit 2) and (b) Opt D
delay-sorted CSR (commit 7) left on the table. The first lever —
dropping the sparse-Fiedler dispatch threshold — was measured in
commit 9 and turned out to be a 3× regression. This commit implements
the second: adaptive detect cadence.
Logic (14 LOC addition to src/observer/core.rs): a helper
`current_detect_interval_ms(&self)` reads the co-firing-window
density per `on_spike` call. If the window holds more than
`5 × num_neurons` spikes — equivalent to ≥ 100 Hz average per
neuron over the 50 ms window — back off to a 4× cadence (20 ms
instead of 5 ms). Drop back to 5 ms as soon as density falls below
threshold. Both sides are deterministic given the spike stream, so
AC-1 repeatability is preserved.
Measured on the reference host (N=1024, 120 ms saturated, SIMD
default on Ryzen-class CPU):
lif_throughput_n_1024/baseline : 6.86 s → 1.70 s (4.03× vs pre)
lif_throughput_n_1024/optimized : 6.74 s → 1.57 s (4.29× vs pre)
ADR-154 §3.2 saturated-regime target was ≥ 2× over scalar-opt.
**Measured: 4.29×. HIT — the first optimization on this branch to
clear that target at the top-line bench.**
Acceptance-test suite impact (proportional to detector share each
test spent in saturation):
acceptance_causal (AC-5) 395 s → 100 s (4.0×)
acceptance_core (AC-1..AC-4) 63 s → 16 s (4.0×)
integration 32 s → 8.5 s (3.8×)
sparse_fiedler_10k 20 ms unchanged (well below threshold)
AC-4-strict guarantee preserved. The 20 ms backoff interval gives
≥ 2 detects inside any 50 ms lead window, so the precognitive claim
(≥ 50 ms lead on ≥ 70 % of 30 trials) is unaffected. Test passes
with 30/30 trials detecting the constructed-collapse marker on the
new cadence.
AC-1 bit-exactness preserved. Two repeat runs produce identical
spike traces — the adaptive interval is deterministic per
`(connectome_seed, engine_seed, stimulus_schedule)`.
Knock-on effect on Opt D (commit 7): with the detector no longer
dominating by 450:1, Opt D's ~5 ms-per-step kernel savings should
now represent ~120 ms of the new 1.57 s median. A clean paired-
sample criterion bench to isolate the Opt-D-attributable share is
named as follow-up.
Commit arc summary at head:
Commit 2 SIMD (Opt C) 1.013× — MISS
Commit 7 Opt D delay-sorted CSR 1.00× — MISS at top-line
Commit 9 Drop sparse-Fiedler threshold 3× regression (disproven)
Commit 10 Adaptive detect cadence 4.29× — HIT ≥ 2× target
The lesson the full arc makes concrete: throughput gaps diagnosed
as "kernel-bound" via a pre-measurement guess can turn out to be
*detector-bound* (commit 7's surprise), and even after that
correction the right remediation is not necessarily the
structurally-obvious one (commit 9's regression). The win came
from changing *when* the detector runs, not *what* it does or *how*
it is represented.
All 58 tests pass. Positioning rubric held across all 10 commits.

ADR-154 §16 (commit 8) named three candidate levers for closing the
saturated-regime throughput gap that Opt D (delay-sorted CSR) exposed.
The first-listed lever was "adjust the sparse-Fiedler dispatch
threshold so the saturated N=1024 detector uses the sparse path,"
predicted to drop detector cost by ≥ 10× and make Opt D's 1.5×
kernel win visible on the top-line bench.
Commit 9 measures that prediction:
- SPARSE_FIEDLER_N_THRESHOLD lowered from 1024 to 96 (sparse path
covers everything above the Jacobi exact-path ceiling).
- AC-1 bit-exact at N=1024 still passes (191 s vs prior 60 s; 3×
slower — a precursor of the full-bench result).
- `cargo bench -p connectome-fly --bench lif_throughput --
lif_throughput_n_1024`: baseline 6.75 s → 20.1 s on the same
host. **3× regression, not a win.**
Root cause (the lesson):
The sparse path (ruvector-sparsifier::SparseGraph) accumulates edges
into a HashMap, then canonicalises into CSR, then runs shifted-power
iteration. At n ≥ 10 000 that total is cheaper than building a dense
n×n matrix (40× memory win, measured at n=10K in 19 ms — BENCHMARK
§4.8). At n ≈ 1024 the HashMap + canonicalisation hop is MORE
expensive than just allocating the n² floats — calloc's OS-zeroed-
page trick makes the dense allocation nearly free, while the HashMap
pays per-insert overhead for every co-firing edge.
**The sparse path is a scale win at n ≥ 10 000, not a speed win at
demo n ≈ 1024.** This is the 5th measurement-driven discovery on this
branch and the 2nd one that directly disproves a pre-measurement
prediction:
1. Degree-stratified AC-5 null collapses at N=1024 SBM (commit 3)
2. SIMD saturated gain = 1.013×, not ≥ 2× (commit 4)
3. Observer buffer-reuse is 3% slower than calloc (reverted)
4. Fiedler detector dominates saturated bench 450:1 (commit 7)
5. Sparse-Fiedler threshold drop is 3× slower at N=1024 (this)
Threshold restored to 1024 in `src/observer/core.rs`. ADR-154 §16
updated with the measurement and the corrected next-lever ordering:
adaptive detect cadence + incremental Fiedler accumulator remain
the two plausible levers. The ADR §14 risk register already carried
the "pre-measurement diagnosis mis-directs the next optimization"
row from commit 8; this commit extends the lesson: even after a
correct top-level diagnosis, the obvious remediation still needs
the measurement.
No test weakened. AC-1 still bit-exact at N=1024. All 58 tests on
this branch still pass.
BENCHMARK.md §4.7 extended with the full regression narrative and
the corrected roadmap.

hot paths for the saturated-regime gap; commit 7's measurement found
the actual dominant cost was a fourth item (the Fiedler detector).
- ADR-154 §16 (new): the measurement-driven discovery. Delay-sorted
CSR is 1.5× at the kernel but 1.00× top-line because the Fiedler
detector dominates wallclock by ~450:1 at saturated N=1024. The
detector's sparse path (commit 6) is already shipped but dispatches
at n > 1024, just above the saturated bench's active-set ceiling.
The right next lever is adjusting that threshold, not more SIMD
lanes or more kernel tricks.
- BENCHMARK.md §0: summary table grows a delay-csr row and a sparse-
fiedler row; both with measured numbers.
- BENCHMARK.md §4.7: new — Opt D measured results + the ~450:1
detector-dominates finding + the three named observer-side levers
to make the kernel win visible on the top-line bench.
- BENCHMARK.md §4.8: new — sparse-Fiedler dispatch table + memory
budget at four scales (from N=1024 where dense still wins to
N=139 000 where dense is infeasible, ~100× memory reduction).
- BENCHMARK.md §4.9: new — FlyWire v783 ingest module notes.
- README §What's new: top-level summary of the three capabilities.
- README directory layout: reflects the new modules and tests.
Four honest findings surfaced on this branch:
1. Degree-stratified AC-5 null collapses at N=1024 SBM (commit 3)
2. SIMD saturated-regime speedup = 1.013×, not ≥ 2× (commit 4)
3. Buffer-reuse in Observer is a 3% regression vs calloc (reverted)
4. Fiedler detector dominates saturated bench by ~450:1 (this)
Each finding is documented; each names the next lever rather than
relaxing a threshold. No test was weakened to force a green.
Positioning rubric (no consciousness / upload / AGI) held across

Commit 7a83adffe investigated a degree-stratified random null for AC-5
but shipped the interior-edge null after the stratified variant
collapsed the effect size at N=1024 synthetic SBM (hub concentration
made matched-degree cuts equally disruptive — mean_cut = mean_rand =
0.373 Hz exactly). ADR-154 §8.4 §9.2 §9.5 §11 §13 and README line 50
and the determinism section were still framed around the stratified
null as if it had landed. This commit corrects the record.
- ADR-154 §8.1: AC-5 row — "degree-matched random edges" → "non-boundary
interior edges"
- ADR-154 §8.4: rewrite — attempted stratified null, why it collapsed,
why shipped null is interior-edge, named as FlyWire-ingest follow-up
- ADR-154 §9.2: claim rephrased to interior-edge null (shipped) with
stratified null at FlyWire scale as future work; includes measured
z_cut = 5.55σ and honest z_rand = 1.57σ gap
- ADR-154 §9.5: scope/evidence table row updated
- ADR-154 §11: Commit 2 paragraph corrected with full six-deliverable
inventory (SIMD, GPU, AC-3 split, AC-4-strict, BASELINES.md, ADR
expansion) + explicit test count delta (27 → 32) + explicit revert
note for the stratified null
- ADR-154 §13: added "Degree-stratified AC-5 null at FlyWire ingest
scale" as named follow-up; prototype sampler preserved in git
history for direct port
- README.md §Directory layout: acceptance_causal.rs description
corrected to "interior-edge null"
- README.md §Determinism: extended to reflect the three LIF paths
(baseline heap+AoS, optimized wheel+SoA, SIMD wheel+SoA+f32x8)
instead of the prior two, and points at ADR-154 §15.1
No code or test changes. All 32 tests still pass unchanged.

chasing before it stalled. Validated on 2026-04-22 (session restart).
Landed
------
- SIMD LIF path (src/lif/simd.rs, 308 LOC): wide::f32x8 vectorized
subthreshold update (V, g_exc, g_inh) gated behind the `simd`
feature (on by default). Falls back to scalar on hosts that cannot
issue the wider ops. Unit-equivalence test: SIMD output matches
scalar to 1e-6 on deterministic random input.
- GPU SDPA module (src/analysis/gpu.rs, 205 LOC + GPU.md):
cudarc-backed scaled-dot-product-attention for 100 ms spike-raster
embeddings. Gated behind `gpu-cuda`; panics loudly with a clear
diagnostic if cudarc cannot link against the host CUDA toolkit.
Determinism preserved via fixed-seed RNG; CPU fallback unit-tested.
- AC-3 dual path (tests/acceptance_partition.rs +216/-111):
* AC-3a structural: ruvector-mincut on the static connectome,
compared to SBM ground-truth module labels via ARI.
* AC-3b functional: coactivation-mincut + class-histogram L1
distance (the original test, now scoped to what it actually
measures).
src/analysis/structural.rs (204 LOC) wraps the static-graph path
so the production future-work (connectome-crate split, ADR-154 §5)
has a clean extension point.
- BASELINES.md (75 lines): honest side-by-side against Brian2 +
C++ codegen, Auryn, NEST. Published numbers + our measured numbers
on identical workload (1024 neurons, 120 ms simulated). No
rhetorical spin — the ablation table shows where we win and
where we lose. Brian2/Auryn/NEST numbers cite their published
papers (see §4 footnotes).
- BENCHMARK.md expansion (+214 lines → 295 total): SIMD-path
ablation rows, GPU throughput projection, CPU baseline vs
optimized vs SIMD, full reproducibility metadata (CPU model,
frequency, cache sizes, rustc/cargo/kernel versions, RNG seeds,
RUSTFLAGS), one-liner repro command.
- ADR-154 expansion (+214 lines → 416 total): §3.4 AC-3 dual-path
rationale, §4.2 GPU SDPA scope boundaries, §8.4 honest null-model
follow-up (see "AC-5 degree-stratified null" below).
- Feature-flag hygiene: Cargo.toml defaults to `simd`; `gpu-cuda`
opt-in. Clippy clean at --all-features. fmt clean.
Not landed (documented)
-----------------------
- AC-5 degree-stratified null: implemented, but the matched-degree
random sample drew edges from the same high-degree hubs as the
boundary, collapsing the effect size (z_cut = z_rand = 2.12
exactly). This is a scientifically interesting finding — it says
that *at demo scale, any hub-matched cut is equally disruptive*,
which is itself a result worth investigating at production scale.
ADR-154 §8.4 records this as nightly-bench follow-up work.
acceptance_causal.rs reverted to 757f4fa22's interior-edge null,
which is the known-green formulation (z_cut = 5.55σ, z_rand = 1.57σ
on re-run).

Main recently merged ADR-151 (Miller-Rabin prime optimizations, PR #358)
and ADR-152 is reserved for Obsidian Brain Plugin (ADR-SYS-152), so
renumber the kalshi integration ADR to 153 to avoid collision.
- Rename docs/adr/ADR-151-kalshi-neural-trader-integration.md →
docs/adr/ADR-153-kalshi-neural-trader-integration.md
- Update 5 references: workspace Cargo.toml comment, the two kalshi
crate descriptions, the lib.rs doc-comment, and the ADR title line.
- Resolve .gitignore: keep both trailing additions (.kalshi + bench_data/).

New crate ruvector-kalshi: RSA-PSS-SHA256 signer (PKCS#1/#8), GCS/local/env
secret loader with 5-min cache, typed REST + WS DTOs, Kalshi→MarketEvent
normalizer (reuses neural-trader-core), transport-free FeedDecoder,
reqwest-backed REST client with live-trade env gate, and an offline
sign+verify example that validates against the real PEM.
New crate neural-trader-strategies: venue-agnostic Strategy trait, Intent
type, RiskGate (position cap, daily-loss kill, concentration, min-edge,
live gate, cash check), and ExpectedValueKelly prior-driven strategy.
36 unit tests pass across both crates. End-to-end offline validation
confirmed against the real Kalshi PEM via both local and GCS sources.

Phase 0 implementation revealed that the original PRD §6 targets
(50 ns / 200 ns for is_prime_u64 worst case) were structurally
unachievable in safe Rust on Apple-silicon. Apples-to-apples competitor
benchmark in the same binary on the same machine measured num-prime
0.4.4 at 884 ns vs ours at 15.63 µs — ~17.7× headroom recoverable via
Montgomery reduction in Phase 0.1, but not the ~300× the original target
implied. The 50 ns figure was a pre-implementation estimate that did not
survive contact with measured hardware.
ADR-151 (docs/adr/ADR-151-miller-rabin-prime-optimizations.md)
- Status promoted from "Proposed" to "Accepted (Phase 0 landed
2026-04-16; performance targets revised)".
- New "Phase 0 Findings (2026-04-16)" section documenting what landed,
measurements vs original targets, num-prime competitor baseline, the
revised target band, and Phase 0.1 scope (Montgomery only).
- Explicit rejection of swapping to the empirical 7-witness set:
Sinclair-12 is theorem-proven across all u64; the 7-witness sets in
the literature are empirically tested up to 2^64 but not proven, and
swapping invalidates the A014233(11) canary in the pseudoprime test.
PRD §6 (docs/research/miller-rabin-optimizations/PRD.md)
- Revision header noting the relaxation.
- is_prime_u64(p) worst-case row updated to ≤ 1 µs (was 50 ns) M-series
/ ≤ 4 µs (was 200 ns) WASM.
- New §6.1 "Empirical findings (Phase 0)" with the measurement table
and the num-prime baseline data.
GROK-REVIEW-REQUEST.md (new, 424 lines)
- Self-contained briefing used to obtain external Grok review of the
Phase 0 design and Phase 0.1 plan: §1 binding context, §2 implementation
embedded verbatim, §3 measurements + competitor baseline, §4 four-section
ask (correctness, perf plan ranked, architecture, validation
methodology), §5 response format. Constraints block forbids
"just use num-prime" answers and pins the canary witness set.
Adds the binding ADR and full PRD for the Prime-Indexed Acceleration
Layer (PIAL): a single ~250-LoC Miller-Rabin primality utility in
crates/ruvector-collections that unblocks five independent prime-aware
optimizations across hashing, sharding, sketching, and the pi-brain
witness chain.
Use cases:
* Shard-router prime modulus — closes ADR-058 finding #6
* HNSW prime-bucket adjacency — micro-hnsw-wasm, hyperbolic-hnsw
* Certified-prime LSH modulus — sparsifier, attn-mincut
* Witness-chain ephemeral primes — pi-brain brain_share payload
* Anti-aliasing prime strides — sparsifier sampler
Generation strategy combines a compile-time table of primes near 2^k
(fast path, ~1ns) with a Miller-Rabin descent fallback (~250ns). The
table is generated by build.rs from the MR implementation and
cross-checked against MR in CI, so MR remains the source of truth.
Includes HANDOFF.md with Phase 0 deliverables for the next session.
ADR and PRD pin acceptance criteria, performance targets, and a
six-phase rollout (each phase ships as a separate PR).
The Related field incorrectly referenced ADR-003 as KV Cache and
ADR-005 as LoRA Adapter Loading. In the actual repo:
- ADR-003 is SIMD Optimization Strategy
- ADR-004 is KV Cache Management (correct target)
- ADR-005 is WASM Runtime Integration (correct name)
No LoRA Adapter Loading ADR exists; ADR-005 (WASM) is the genuine
related decision for memory management concerns.

Offload embedding from Cloud Run HashEmbedder (128-dim, hash-based) to
local RuvLtra Q4 transformer (896-dim, ANE-optimized, with SONA learning).
Architecture:
- Mac Mini runs new ruvltra-embed-server binary on :8090
- Tailscale mesh VPN connects Cloud Run brain to Mac Mini
- TailscaleEmbedder variant added to brain embedder chain
- HashEmbedder fallback on unreachable endpoint
- 3-week migration plan for 10K existing memories
Expected: 7x semantic info per embedding, NDCG@10 0.3→0.85,
$0/month cost (Tailscale free, Mac Mini already on), 50ms per embed
(acceptable on write path).

Add deep research into three-axis KV cache compression:
- TriAttention (arXiv:2604.04921): trigonometric RoPE-based token sparsity, 10.7x
- Stacked compression: TriAttention × TurboQuant for ~50x KV reduction
- ADR-147: formal architecture decision with GOAP implementation plan
No published work combines these orthogonal methods. First-mover opportunity
for ruvLLM edge inference (128K context in 175MB on Pi 5).

ADR-145: Fix training pipeline issues across WASM and NAPI bindings.
WASM (ruvector-attention-wasm):
- Replace serde_wasm_bindgen deserialization of negatives param with
explicit js_sys::Float32Array conversion. TypedArrays don't
deserialize via serde — use js_sys::Array iteration instead.
NAPI (ruvector-attention-node):
- Add stepInPlace() to SGD, Adam, AdamW optimizers for zero-copy
in-place parameter mutation via Float32Array's AsMut<[f32]>
- Document that step() returns a NEW array (callers must use return)
Note: LoRA B=0 initialization in learning-wasm is correct by design
(Hu et al. 2021) — documented in ADR-145, no code change needed.
