From 95f28f786488622d93198b42d2f56628b9ebc0e0 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 15 Sep 2026 07:42:33 +0000 Subject: [PATCH 1/4] feat(agent-memory): add direct MinCutBuilder boundary detection (ADR-346) Add BoundaryMethod::DirectBuilder to MincutGatedForgetting as an opt-in alternative to RuVectorGraphAnalyzer::from_knn(...).partition() (ADR-345's original, still-default WrapperPartition), following up on ADR-345's "Next Research item 1". Uses ruvector_mincut::MinCutBuilder's one-shot construction instead of MinCutWrapper's up-to-100-instance replay loop, with the same distance-to-weight inversion and unordered-pair edge dedup RuVectorGraphAnalyzer::from_knn applies internally.

The existing +`BoundaryMethod::WrapperPartition` remains the default returned by +`MincutGatedForgetting::soft`/`::hard`, so this change is purely additive: +no existing caller's behavior changes. `MincutGatedForgetting` itself +remains **not** promoted to a recommended or default compaction policy — +that verdict, from ADR-345, is unchanged by this ADR. + +## Context + +ADR-345 (`docs/research/nightly/2026-09-05-mincut-gated-forgetting`) +measured `MincutGatedForgetting`'s only boundary-detection method at the +time — `ruvector_mincut::RuVectorGraphAnalyzer::from_knn(...).partition()` +— at ~1,800-2,700x the `CoherencePolicy` baseline's compaction latency +(FAIL vs. a pre-registered <=100x gate) and non-deterministic across +repeated calls on an *identical, unchanged* graph (50% empty-result rate +over 30 trials on a fixed 19-vertex two-clique-plus-bridge topology). It +rejected the separate hypothesis that the resulting structural signal +improves bridge-memory survival (0.0pp measured gap vs. a >=15pp gate — +either failure alone would have been sufficient for rejection). + +ADR-345 left three explicit open questions for future work; "Next Research +item 1" asked: does calling `ruvector_mincut::DynamicMinCut` (or +`ClusterHierarchy`) directly, instead of through +`RuVectorGraphAnalyzer`/`MinCutWrapper`, avoid the measured latency and +determinism problems? This ADR answers that question. + +Investigation of `ruvector-mincut`'s internals +(`crates/ruvector-mincut/src/{integration,wrapper,algorithm}/mod.rs`) found +the root cause: `RuVectorGraphAnalyzer::partition()` routes through +`MinCutWrapper::process_instances()`, which lazily builds and replays every +edge into up to `MAX_INSTANCES = 100` geometrically-scaled `BoundedInstance` +data structures per call until one reports `ValueInRange` — expensive by +construction, and its result depends on which instance happens to answer +first, which is sensitive to `DashMap`/hash-map iteration order rather than +any property of the graph (no `rand` usage was found anywhere in the +`algorithm`, `instance`, or `witness` modules). By contrast, a one-shot +`ruvector_mincut::MinCutBuilder::with_edges(edges).build()` call does a +single `DynamicMinCut::from_graph` pass (one spanning-forest DFS plus one +tree-edge-cut computation over the resulting spanning tree) — algorithmically +far cheaper per query and untouched by `MinCutWrapper`'s machinery. + +## Hypothesis + +```text +Given the identical ADR-345 84-entry corpus (6 clusters x 12 core memories + +12 interpolated bridges, 32-dim, same hot-cluster access simulation, same +k-NN parameters, seed=341) and MincutGatedForgetting configuration, + +when boundary detection uses BoundaryMethod::DirectBuilder (one-shot +MinCutBuilder::with_edges(...).build()) instead of +BoundaryMethod::WrapperPartition (RuVectorGraphAnalyzer::from_knn(...).partition()), + +then compaction wall-clock slowdown vs. the CoherencePolicy baseline should +fall from the previously measured ~1,800-2,700x toward the pre-existing +100x gate, and per-call boundary-detection latency on a scaling probe +(n=19..400) should drop by at least an order of magnitude with +qualitatively better (near-linear, not super-linear) scaling, + +subject to: (a) cargo test remaining green (no regression to the unchanged +WrapperPartition path or to bridge-detection correctness in the unit-test +topology), and (b) the determinism probe (30 trials, identical fixed graph) +showing a materially lower empty-result rate than WrapperPartition's +measured 27-57%. + +This hypothesis is scoped to ADR-345's item 1 (latency and determinism) +only. It does NOT re-litigate ADR-345's separate, already-rejected +"does the structural signal improve bridge survival" hypothesis — changing +that hypothesis's acceptance criteria after seeing new results would +violate the nightly research process's own rule against redefining a +hypothesis post hoc. Bridge-survival and recall are measured and reported +as additional evidence, not as gates for this ADR's decision. +``` + +Full methodology and complete raw output (6 repeated runs of the main +benchmark, 2 repeated runs of the scaling probe, 3 runs of the determinism +probe including one invalidated run kept for the record) are in +`docs/research/nightly/2026-09-15-direct-mincut-bridge-detection/README.md` +and its `raw-runs.txt`. + +## Decision + +1. Add `ruvector_agent_memory::graph_forget::BoundaryMethod` (`WrapperPartition` + | `DirectBuilder`) and a `boundary_method` field on `MincutGatedForgetting`. + `soft()`/`hard()` default it to `WrapperPartition` — **no behavior change** + for any existing caller (there are none outside this crate's own examples + and tests, but the invariant is preserved regardless). +2. Implement `DirectBuilder` via `ruvector_mincut::MinCutBuilder::new() + .with_edges(edges).build()` + `.partition()`, converting the k-NN + neighbor list's raw cosine *distance* to an edge *weight* (`1/distance`) + to match `RuVectorGraphAnalyzer::from_knn`'s own convention — the first + implementation attempt skipped this conversion and produced an + incorrect, inverted cut structure (unit tests caught it immediately; see + the nightly README's "Failure modes"). +3. Deduplicate the k-NN neighbor list's directed `(i,j)`/`(j,i)` pairs by + unordered vertex pair before constructing edges: `MinCutBuilder`'s + underlying `DynamicGraph::insert_edge` rejects a second insert of the + same undirected pair with `EdgeExists`, failing `build()` immediately — + a second bug this experiment's own probe scripts hit and fixed (also + documented in "Failure modes"). +4. Extend the existing `mincut_scaling_probe` and `mincut_determinism_probe` + examples to measure `DirectBuilder` alongside the unchanged + `WrapperPartition` measurement on identical inputs, and add a new + `mincut_direct_builder_bench` example (the original + `mincut_gated_forgetting_bench` from ADR-345 is left unmodified as a + historical artifact of that ADR). +5. **Do not change `MincutGatedForgetting::soft`/`::hard`'s default.** + `DirectBuilder` is recommended for any future use of + `MincutGatedForgetting` that needs the structural signal at interactive + latency, but this experiment surfaced a real, fully reproducible + divergence in *which* minimum cut each method finds on the ADR-345 + corpus (see Evidence) that is not yet understood well enough to justify + silently changing the default for a policy that ADR-345 already + declined to promote. + +## Evidence + +Full raw output in the linked nightly README/raw-runs.txt; summarized here. + +**Scaling probe** (ring k-NN, k=8, n in {19,50,100,200,400}), two repeated +runs: + +| n | wrapper_partition | direct_builder | speedup | +|---:|---:|---:|---:| +| 19 | 69,663.9ms / 68,435.9ms | 0.40ms / 0.36ms | 173,462x / 188,894x | +| 50 | 86.8ms / 71.1ms | 1.95ms / 1.17ms | 44x / 61x | +| 100 | 536.7ms / 410.4ms | 4.01ms / 2.82ms | 134x / 145x | +| 200 | 2,679.2ms / 2,408.2ms | 28.97ms / 8.03ms | 93x / 300x | +| 400 | 11,481.6ms / 11,070.0ms | 22.40ms / 21.07ms | 512x / 525x | + +`wrapper_partition` numbers reproduce ADR-345's original scaling table +(69,269.9 / 76.8 / 481.3 / 2,712.9 / 11,415.0ms) within run-to-run noise, +including the same n=19 multi-second-to-outlier behavior. `direct_builder` +scales near-linearly (sub-millisecond to ~20-30ms across a 21x increase in +n); `wrapper_partition` does not. + +**Determinism probe** (fixed 19-vertex two-clique-plus-bridge graph, 30 +trials), after fixing this experiment's own edge-dedup bug (see Decision +item 3 and "Failure modes" in the README): + +| Method | empty/degenerate | bridge correctly flagged | avg latency/call | +|---|---:|---:|---:| +| wrapper_partition (run B) | 8/30 (27%) | 22/30 (73%) | 846.1ms | +| wrapper_partition (run C) | 15/30 (50%) | 15/30 (50%) | 787.4ms | +| direct_builder (run B) | 0/30 (0%) | 30/30 (100%) | 0.2ms | +| direct_builder (run C) | 0/30 (0%) | 30/30 (100%) | 0.2ms | + +Run C's wrapper numbers (50%/50%) are an exact reproduction of ADR-345's +originally reported 50% empty-result rate. `direct_builder` was empty 0/60 +times and correctly flagged the bridge 60/60 times across both runs — fully +deterministic on this topology, at ~4,000x lower per-call latency. + +**Main benchmark** (identical 84-entry corpus/seed to ADR-345), 6 repeated +runs: + +| Metric | Candidate A (wrapper) | Candidate B (direct) | +|---|---:|---:| +| Slowdown vs. baseline (Soft) | 2,453x-2,800x (6/6 FAIL vs <=100x) | 65x-105x (5/6 PASS, 1/6 FAIL) | +| Slowdown vs. baseline (Hard) | 2,163x-2,778x (6/6 FAIL vs <=100x) | 72x-106x (5/6 PASS, 1/6 FAIL) | +| Speedup, B vs. A | — | 25.9x-33.7x, stable across all 6 runs | +| Bridge survival (Soft) | 66.7% (all 6 runs; matches ADR-345 exactly) | 50.0% (all 6 runs, deterministic) | +| Bridge survival (Hard) | 66.7% (all 6 runs) | 58.3% (all 6 runs, deterministic) | +| Recall@10 | 100.0% (all runs, both candidates) | 100.0% (all runs, both candidates) | + +Candidate A's slowdown here (2,163x-2,800x) falls within ADR-345's reported +"1,800-2,700x range depending on run" — a reproducibility check on the +original result, passed.

This is +reported as a limitation of the inherited ratio-based gate at this corpus's +absolute scale (baseline latency in the tens of microseconds), not as +evidence against the underlying, very large and very consistent, absolute +latency improvement. + +**Unresolved finding:** Candidate B's bridge survival (50.0%/58.3%) is +lower than candidate A/baseline's (66.7%) on this corpus, deterministically +and reproducibly across all 6 runs (zero variance — unlike candidate A's +own non-determinism at `mincut_trials=1`).

This is evidence that the two methods are **not** +behaviorally interchangeable beyond latency/determinism, and is exactly why +this ADR does not change `MincutGatedForgetting`'s default despite +`DirectBuilder`'s decisive performance win. + +## Consequences + +- Anyone who does enable `mincut-forget` and wants `MincutGatedForgetting` + at practical latency now has a documented, tested option + (`boundary_method = BoundaryMethod::DirectBuilder`) that is 25-500x + faster and fully deterministic on every topology measured here, instead + of the ADR-345-rejected default path. +- ADR-345's overall verdict — do not promote `MincutGatedForgetting` as a + recommended or default compaction policy — is unaffected. This ADR closes + one of its three open questions (item 1) without reopening the others + (items 2 and 3, and the new bridge-selection-divergence finding above, + remain open). +- The `RuVectorGraphAnalyzer`/`MinCutWrapper` performance and determinism + characteristics documented here are a hardening finding against + `ruvector-mincut` itself, independent of `ruvector-agent-memory`: any + other caller of `RuVectorGraphAnalyzer::partition()` for a single one-shot + query (rather than the incremental-update use case `MinCutWrapper` + appears designed for) would likely see the same latency and determinism + characteristics, and may want the same one-shot `MinCutBuilder` + alternative. + +## Alternatives + +- **`DynamicCanonicalMinCut`** (feature `canonical`, + `crates/ruvector-mincut/src/canonical/dynamic/mod.rs`): incremental + `add_edge`/`remove_edge` skip full recomputation when a mutation + provably doesn't cross the cached cut — genuinely O(1)-amortized for + incremental updates, but `MincutGatedForgetting` rebuilds its k-NN graph + from scratch on every compaction call (no incremental edge stream to + exploit), so this ADR's one-shot `MinCutBuilder` is the simpler, equally + fast choice for this call pattern. Left as a candidate for a future + incremental-compaction design. +- **`ClusterHierarchy`** (`crates/ruvector-mincut/src/cluster/mod.rs`): not + used — its `compute_cluster_boundary`/`compute_vertex_boundary` do a full + O(E) edge scan per cluster on every `rebuild()`, offering no latency + advantage over `MinCutBuilder` for this single-shot use case while + requiring a different graph-construction API. +- **`canonical::source_anchored::canonical_mincut`** (feature `canonical`): + a deterministic-by-design, fixed-vertex-ordering Stoer-Wagner + implementation with an explicit tie-breaking rule — a strictly stronger + determinism guarantee than `MinCutBuilder`'s (which is deterministic *in + practice*, per the measured 0/60 empty-result rate, but not proven so by + construction the way the canonical module documents itself to be). Not + used here to keep this experiment's scope to the exact API ADR-345 named + (`DynamicMinCut`) and avoid pulling in the `canonical` feature; worth + revisiting for the "different cut selection" finding above, since a + canonical construction might make the two methods' divergence + *analyzable* (which cut is "more correct") rather than just observed. + +## Implementation Plan + +Complete as of this ADR: `BoundaryMethod` enum and `boundary_method` field +on `MincutGatedForgetting`, `boundary_from_one_partition_direct` (edge +weight inversion + unordered-pair dedup), extended `mincut_scaling_probe` +and `mincut_determinism_probe` examples, new `mincut_direct_builder_bench` +example, three new unit tests mirroring the existing `WrapperPartition` +bridge-dataset tests for `DirectBuilder`. + +## API Shape + +```rust +#[derive(Debug, Clone, Copy, PartialEq, Eq)] +pub enum BoundaryMethod { + WrapperPartition, // default; ADR-345's original, unchanged candidate + DirectBuilder, // this ADR's candidate +} + +pub struct MincutGatedForgetting { + // .. unchanged fields .. + pub boundary_method: BoundaryMethod, // new; defaults to WrapperPartition +} +``` + +## Feature Flags + +No change: still gated entirely behind `mincut-forget` (optional +`ruvector-mincut` path dependency), off by default, exactly as ADR-345 left +it. + +## Benchmark Evidence + +See "Evidence" above and `docs/research/nightly/2026-09-15-direct-mincut-bridge-detection/README.md` / `raw-runs.txt` for full raw output across all repeated runs. + +## Security + +No new cryptographic primitive or witness-chain change. `DirectBuilder` +calls only safe, already-in-tree `ruvector-mincut` public API +(`MinCutBuilder`); it does not touch `witnessed_compaction`'s tamper-evident +eviction ledger, which ADR-345 already covers and which this ADR's +benchmark does not re-measure (no new claim is made about it). + +## Governance + +None beyond ADR-345's existing "no witness, no mutation" invariant, which +this ADR does not touch. + +## Failure Modes + +Two bugs surfaced and were fixed during this experiment (both documented in +the nightly README in full and summarized in "Decision" above): +missing distance-to-weight inversion (caught immediately by the new unit +tests failing), and missing reverse-direction edge deduplication in the +probe scripts (caught by an obviously-wrong `0.0ms`/100%-empty reading, +which by the "never hide failures" rule is kept in `raw-runs.txt` alongside +its diagnosis and fix rather than silently discarded). + +The unresolved cut-selection divergence (bridge survival 50.0%/58.3% vs. +66.7%) is not a "failure mode" of this ADR's own gated hypothesis +(latency/determinism), but is documented as an open risk for anyone +choosing `DirectBuilder` expecting behavioral parity with `WrapperPartition` +beyond speed. + +## Migration + +None: `boundary_method` is a new field defaulting to the prior sole +behavior; no existing caller's output changes. + +## Rollback + +Remove `BoundaryMethod`, the `boundary_method` field, and +`boundary_from_one_partition_direct` with no impact on any existing +caller — `WrapperPartition` remains fully self-contained and unchanged. + +## Rejection Criteria + +This ADR's narrow hypothesis (latency + determinism improvement) is +accepted: `DirectBuilder` reproducibly and by a large margin outperforms +`WrapperPartition` on both axes across every run. It would have been +rejected had `DirectBuilder` failed to clear at least an order-of-magnitude +latency improvement, or shown any non-zero empty-result rate on the +determinism probe; neither occurred in any of the runs recorded here. + +## Open Questions + +1. Why do `WrapperPartition` and `DirectBuilder` select different minimum + cuts on the ADR-345 84-entry corpus, and which (if either) is "more + correct" for the bridge-protection use case? A canonical, fixed + tie-breaking construction (`canonical::source_anchored::canonical_mincut`, + see "Alternatives") may make this analyzable rather than just observed. +2. Would `DynamicCanonicalMinCut`'s true incremental amortized updates + matter if `MincutGatedForgetting` were redesigned to maintain its k-NN + graph incrementally across compaction calls instead of rebuilding it + from scratch each time? Out of this ADR's scope. +3. ADR-345's own remaining open questions (its items 2 and 3 — the exact + internal source of `MinCutWrapper`'s non-determinism, and whether the + "outlier isolation, not bridge isolation" finding holds on real + embeddings) are untouched by this ADR. diff --git a/docs/adr/INDEX.md b/docs/adr/INDEX.md index ffd65a6d0a..b8179612c5 100644 --- a/docs/adr/INDEX.md +++ b/docs/adr/INDEX.md @@ -1,6 +1,6 @@

"Next Research item 1" +**Acceptance:** **ACCEPT** (narrow scope: latency + determinism only) — see [Acceptance result](#acceptance-result) + +## Summary + +ADR-345 rejected `MincutGatedForgetting` — a `ruvector-agent-memory` +compaction policy that uses `ruvector-mincut`'s minimum-cut graph analysis to +protect structurally load-bearing "bridge" memories during eviction — on two +independent grounds: the structural signal didn't measurably help +(0.0pp bridge-survival gap vs. a 15pp gate), and it was catastrophically slow +and non-deterministic (~1,800-2,700x baseline latency vs. a 100x gate; 50% +empty-result rate across repeated calls on an identical graph). It traced +both problems to a single API choice — `RuVectorGraphAnalyzer:: +from_knn(...).partition()` — and left as an explicit open question whether +calling `ruvector-mincut`'s lower-level `DynamicMinCut` API directly would +avoid them. + +This experiment answers that question. Reading `ruvector-mincut`'s +internals (not just its docs) found the exact mechanism: +`RuVectorGraphAnalyzer::partition()` routes through `MinCutWrapper:: +process_instances()`, which replays every edge into up to 100 +geometrically-scaled `BoundedInstance` structures per call until one +answers — expensive by construction, and its result depends on hash-map +iteration order rather than the graph. A one-shot +`ruvector_mincut::MinCutBuilder::with_edges(edges).build()` call instead +does a single spanning-forest-plus-tree-edge-cut pass, bypassing that +machinery entirely. + +Implementing this as a new `BoundaryMethod::DirectBuilder` option (alongside +the unchanged `BoundaryMethod::WrapperPartition`) and re-running ADR-345's +exact benchmark, scaling probe, and determinism probe on identical inputs +found: **25x-525x faster per-call latency depending on graph size, 0% +empty-result rate over 60 determinism-probe trials (down from 27-57%), and +a compaction-latency ratio to baseline that clears the inherited 100x gate +in most (10/12) individual measurements** — while also surfacing a new, +fully reproducible finding that the two methods select *different* minimum +cuts on the same graph, with `DirectBuilder` protecting fewer of the +corpus's bridge memories than `WrapperPartition` did at +`mincut_trials=1` on this specific seed. Two implementation bugs (a missing +distance-to-weight inversion, and a missing edge-deduplication step) were +found and fixed during this experiment and are documented in full below, +per the nightly process's "never hide failures" rule. + +## Hypothesis + +```text +Given the identical ADR-345 84-entry corpus (6 clusters x 12 core memories + +12 interpolated bridges, 32-dim, same hot-cluster access simulation, same +k-NN parameters, seed=341) and MincutGatedForgetting configuration, + +when boundary detection uses BoundaryMethod::DirectBuilder (one-shot +MinCutBuilder::with_edges(...).build()) instead of +BoundaryMethod::WrapperPartition (RuVectorGraphAnalyzer::from_knn(...).partition()), + +then compaction wall-clock slowdown vs. the CoherencePolicy baseline should +fall from the previously measured ~1,800-2,700x toward the pre-existing +100x gate, and per-call boundary-detection latency on a scaling probe +(n=19..400) should drop by at least an order of magnitude with +qualitatively better (near-linear, not super-linear) scaling, + +subject to: (a) cargo test remaining green, and (b) the determinism probe +(30 trials, identical fixed graph) showing a materially lower empty-result +rate than WrapperPartition's measured 27-57%. +``` + +This hypothesis is deliberately scoped to ADR-345's "Next Research item 1" +(latency and determinism) only. ADR-345's separate, already-rejected +hypothesis — does the structural signal improve bridge survival? — is +**not** re-litigated here (bridge survival and recall are measured and +reported as additional context, not as gates for this experiment's +accept/reject decision; redefining a rejected hypothesis's acceptance +criteria after seeing new results is exactly what the nightly process's +Step 32 forbids). + +## Why this matters now (2026) + +Agent-memory systems increasingly need *structural* (graph-aware) signals +on top of scalar recency/frequency scoring — GraphRAG, causal-episodic +fusion, and multi-hop retrieval all depend on connectivity surviving +compaction. `ruvector-mincut` already has a general dynamic min-cut engine +in-tree; whether the rest of the ecosystem can actually *use* it at +interactive latency, rather than only as an offline analysis tool, is a +load-bearing question for every future feature that wants a live structural +signal (this nightly's own `ruvector-memory-admission`/ADR-344 and +`graph_forget`/ADR-345 both hit the same wall independently). + +## Why this could matter in 2036 + +A decade out, agent memory is plausibly not a flat vector store with a +scalar eviction score at all, but a live graph whose structural properties +(cut vertices, community boundaries, expansion) gate admission, retention, +and retrieval jointly — "coherence domains" in the RVM sense. That future +requires graph analysis primitives that are fast enough to run inline, not +just fast enough to run as a nightly batch job. This experiment is a small, +concrete step toward knowing which of `ruvector-mincut`'s APIs are already +suitable for that role and which still need work. + +## Why this could matter in 2046 + +If autonomous, self-modifying agent infrastructure (this repo's own +long-horizon thesis) needs to reason about its own memory's structural +integrity as part of routine operation — not as a periodic audit — the +primitives it reasons *with* need both correctness and a cost model cheap +enough to run continuously. An engine whose one-shot query cost varies by +5+ orders of magnitude with graph size and returns a different answer 50% +of the time on an unchanged input cannot be that primitive. This experiment +demonstrates a design (single deterministic pass, no incremental-update +machinery in the query path) that scales far better, even though the +specific policy built on top of it (`MincutGatedForgetting`) remains +unpromoted. + +## RuVector ecosystem fit + +- **`ruvector-mincut`**: the engine under test; this experiment is a + hardening/usage-pattern finding against its own public API, not a change + to it (`MinCutBuilder`/`DynamicMinCut` are pre-existing, unmodified). +- **`ruvector-agent-memory`**: the consumer (`graph_forget` module), + extended with a second `BoundaryMethod`. +- **MetaHarness**: `npx metaharness --help` is installed in this + environment (v0.4.16, auto-installed on first invocation) but its + subcommands (`score`/`analyze`/`genome`/`learn`/`avo`/`proxy`) are + project-scaffolding and repo-readiness tools, not a research-orchestration + API applicable to an in-repo, single-crate experiment like this one; it + was not used for this run beyond this capability check. +- **`ruvector` harness CLI** (`doctor`/`darwin`/`flywheel`/`status` + subcommands referenced by the nightly process template): **not + installed** in this environment (`npx ruvector harness ...` returns "could + not determine executable to run" for all four subcommands checked).

No new persistent state is introduced — both +methods build and discard their graph structure per compaction call. + +## Performance math + +`DirectBuilder`'s measured near-linear scaling (0.36ms @n=19 to ~21-29ms +@n=400, a ~60-80x latency increase for a 21x vertex-count increase) is +consistent with `DynamicMinCut::from_graph`'s documented cost: one O(V+E) +DFS spanning-forest construction plus one O(V+E) BFS-based tree-edge-cut +computation. `WrapperPartition`'s cost is dominated by +`MinCutWrapper::process_instances`'s up-to-100-instance replay loop, each +instance re-inserting every edge — an O(100 \* E) or worse bound depending +on how quickly `get_search_start`'s binary-search hint converges, which +this experiment did not further decompose (out of scope; see "Next +research"). + +## Failure modes + +Two real implementation bugs were found and fixed during this experiment, +both caught by the harness's own correctness checks rather than slipping +through: + +1. **Missing distance-to-weight inversion.** The first + `boundary_from_one_partition_direct` implementation passed the k-NN + neighbor list's raw cosine *distance* directly to `MinCutBuilder` as an + edge *weight*. `RuVectorGraphAnalyzer::from_knn` inverts this + (`weight = 1/distance`) so near-duplicate (low-distance) pairs get + heavy, cut-resistant edges; skipping that inversion makes + near-duplicate intra-cluster edges look *cheap* to cut, inverting the + intended cut structure. This was caught immediately: the new + `direct_builder_soft_mode_protects_the_structural_bridge` and + `..._hard_mode_...` unit tests failed on first run (the algorithm + isolated an arbitrary plain cluster member instead of the bridge). + Fixed by applying the identical `1/distance` inversion; both tests then + passed. +2. **Missing reverse-direction edge deduplication in probe scripts.** The + k-NN neighbor list is directed and can list `(i,j)` without `(j,i)`, but + the *union* of all vertices' neighbor lists can still contain both + directions for the same undirected pair. `graph_forget.rs`'s own + `boundary_from_one_partition_direct` already deduplicated by unordered + pair, but the standalone `mincut_scaling_probe.rs` and + `mincut_determinism_probe.rs` probe scripts (written independently, for + a different synthetic graph shape) initially did not. `DynamicGraph:: + insert_edge` rejects a second insert of the same undirected pair with + `EdgeExists`, and `MinCutBuilder::build()` propagates that error via + `?` on the very first duplicate — so the bug manifested as `build()` + failing on essentially every trial, producing a suspicious + `avg_per_call=0.0ms`, `empty_or_degenerate=100%` reading that was + caught by inspection (an "instant, always-empty" result is not + plausible for a real computation) rather than by an assertion. Recorded + in `raw-runs.txt`'s "Run A" under section 3, kept for the record per the + nightly process's "never hide failures" rule, alongside the fix (dedup + by unordered pair, matching `graph_forget.rs`) and the corrected re-run. +3. **The <=100x latency gate is noise-sensitive at this corpus's absolute + scale.** The `CoherenceWeighted` baseline takes only ~30-35 + microseconds; `DirectBuilder`'s absolute compaction time is stable + (2.2-3.6ms across 6 runs) but dividing by a tens-of-microseconds + denominator makes the resulting *ratio* cross the 100x line in either + direction depending on run-to-run OS/allocator jitter on the baseline + side alone. 2 of 12 individual ratio measurements (1 Soft, 1 Hard, out + of 6 runs each) exceeded 100x despite the underlying absolute latency + being consistently fast. This is reported as a measurement-methodology + limitation of a gate inherited from ADR-345's much-slower baseline + comparison, not as a finding against `DirectBuilder` itself. +4. **Cut-selection divergence** (not a bug, but an unresolved and + important finding): see "Rejected alternatives" is not the right + heading for this — see the dedicated callout in ADR-346's Evidence + section and "Next research" below. + +## Rejected alternatives + +- **`DynamicCanonicalMinCut`** (feature `canonical`): true incremental + O(1)-amortized updates via `add_edge`/`remove_edge`, but + `MincutGatedForgetting` rebuilds its k-NN graph from scratch every + compaction call with no incremental edge stream to exploit — no latency + advantage over a one-shot `MinCutBuilder::build()` for this call pattern. +- **`ClusterHierarchy`**: `compute_cluster_boundary`/`compute_vertex_boundary` + do a full O(E) scan per cluster on every `rebuild()` — no latency + advantage, different (more complex) construction API. +- **`canonical::source_anchored::canonical_mincut`** (feature `canonical`): + a genuinely stronger determinism guarantee (deterministic *by + construction*, not just *in practice*) via fixed-order Stoer-Wagner + tie-breaking. Not used here to keep this experiment's scope to the exact + API ADR-345 named (`DynamicMinCut`/`MinCutBuilder`) without pulling in an + additional feature flag; flagged in "Next research" as the natural next + step for investigating the cut-selection divergence. + +## Security + +No new cryptographic primitive, no witness-chain change. `DirectBuilder` +calls only pre-existing, safe `ruvector-mincut` public API. It does not +touch `witnessed_compaction`'s tamper-evident eviction ledger (ADR-345), +which this experiment does not re-measure. + +## Governance + +None beyond ADR-345's existing "no witness, no mutation" invariant, +untouched by this change. + +## MCP surface analysis + +Not applicable. `graph_forget` exposes no MCP tool today, and this +experiment (a boundary-detection method swap) creates no new capability +that would justify one — it's an internal performance choice within an +existing, already-unpromoted policy. + +## WASM / edge implications + +Not measured this run. `MinCutBuilder`'s dependency graph +(`ruvector-mincut`'s `algorithm`/`graph`/`tree`/`euler`/`linkcut` modules) +is pure Rust with no obvious WASM-hostile primitives (no threads assumed at +the `DynamicMinCut::from_graph` call path used here, though `DynamicGraph` +itself uses `DashMap` internally, which has its own WASM considerations not +investigated in this experiment). No deployment claim is made. + +## RVF integration analysis + +Applicable in principle, not implemented this run: a `MincutGatedForgetting` +configuration (including its now-two-valued `boundary_method` choice) is +small, serializable state that could travel inside an RVF portable +cognitive package alongside the memory store it compacts, giving a +receiving agent the exact same compaction behavior. Not pursued because +`MincutGatedForgetting` itself remains unpromoted (ADR-345) — packaging an +unpromoted policy for portability would be premature. + +## RVM integration analysis + +Not applicable. Boundary detection is a stateless, per-call computation +with no privileged operation, isolation boundary, or inter-agent +communication surface that RVM enforcement would add value to. + +## ruFlo integration analysis + +A concrete, narrow fit: ruFlo could run `mincut_scaling_probe` and +`mincut_determinism_probe` on a schedule against new `ruvector-mincut` +releases as a regression watch — both are already fast, deterministic +(modulo the exact non-determinism this experiment measures, which is +itself the signal), and produce a single pass/fail-style number +(empty-result rate, latency-vs-n slope) suitable for an automated gate. Not +implemented this run (no ruFlo workflow definition changed); flagged as a +concrete, low-effort follow-up rather than a vague "ruFlo could orchestrate +this." + +## Practical applications + +1. **Agent memory bridge protection** (the original ADR-345 use case) — now + has a latency-practical boundary-detection primitive available, if a + future experiment resolves the cut-selection divergence and re-attempts + the bridge-survival hypothesis. +2. **GraphRAG connectivity checks** — any pipeline that needs "is this node + a cut vertex in the current retrieval graph" at query time, not just + offline, benefits from the same latency finding. +3. **Streaming index health checks** — `ruvector-hnsw-repair` or similar + could use a fast one-shot min-cut as a cheap "did this delete + fragment the graph" check. +4. **CI regression gates for `ruvector-mincut` itself** — the scaling and + determinism probes extended here are directly reusable as a release gate + (see "ruFlo integration analysis"). +5. **Code-intelligence dependency graphs** — detecting structurally critical + files/symbols (cut vertices in an import graph) at IDE-interactive + latency, not batch-analysis latency. +6. **Security retrieval** — identifying single points of semantic failure + in a threat-intel or incident-response knowledge graph before evicting + low-access-frequency nodes. +7. **Enterprise retrieval namespace merges** (`ruvector-namespace-merge`, + 2026-08-08 nightly) — any merge-time structural check gated on min-cut + cost now has a faster primitive to build on. +8. **Local-first assistants** — on-device compaction decisions where even + the "background job" latency bar (this ADR's 100x gate) needs to be much + lower in absolute terms (milliseconds, not tens of milliseconds) for a + responsive local agent; `DirectBuilder`'s 2-4ms absolute cost at n=84 is + far closer to that bar than `WrapperPartition`'s 70-95ms. + +## Long horizon applications + +1. **Self-healing graph memory**: requires min-cut analysis cheap enough to + run on every write, not every nightly batch — this experiment is a data + point on how close current `ruvector-mincut` APIs are to that bar (much + closer via `DirectBuilder`, still not "every write" cheap at large n). +2. **Synthetic nervous systems** (`ruvector-nervous-system`): structural + integrity signals as a continuous background process rather than a + periodic audit. +3. **Agent operating systems**: memory-subsystem introspection + ("is my memory graph fragmenting") as an OS-level health metric. +4. **Autonomous edge cognition**: the same latency requirement as #1, at + even tighter power/compute budgets. +5. **Swarm memory**: shared, structurally-aware memory across multiple + agents needs consistent (deterministic) structural signals across + nodes — this experiment's determinism finding is directly relevant. +6. **Dynamic world models**: cut-vertex detection as a primitive for + identifying causally load-bearing state in a learned world model's + internal graph representation. +7. **Proof-gated autonomous infrastructure**: a structural-integrity check + cheap enough to run as a pre-condition on every mutation, not a + post-hoc audit. +8. **Robotics memory**: similar latency/determinism requirements to edge + cognition, with harder real-time constraints. + +For each: the primary uncertainty is the same one this experiment surfaced +(does the fast method give the *same answer* as the slow one, not just a +faster one) and the falsification path is the same as this experiment's +methodology — a fixed, known-answer topology plus repeated trials. + +## Evolution results (Darwin) + +Not run. `npx ruvector harness darwin --help` is not installed in this +environment (see "RuVector ecosystem fit" above for the exact check and +result). No bounded-evolution search was performed; the two candidates +compared here were hand-selected pre-existing `ruvector-mincut` APIs. + +## Promotion decision + +`BoundaryMethod::DirectBuilder` is **accepted** as an available option on +`MincutGatedForgetting`, off-by-default-unchanged (see ADR-346's Decision). +`MincutGatedForgetting` as a whole remains **not promoted** to a +recommended or default compaction policy (ADR-345's verdict, unchanged). + +## Witness evidence + +No cryptographic witness chain applies to this experiment (it doesn't touch +`witnessed_compaction`). Evidence integrity here is: fixed seeds, raw +command output preserved verbatim in `raw-runs.txt` (including the +invalidated run and its diagnosis), 6/2/3 repeated runs per measurement +category with all values reported (not just favorable ones), and an exact +reproduction of two of ADR-345's own committed numbers (the 66.7%/100.0%/ +0.0pp-gap bridge-survival-and-recall result, and the 50%/50% +empty-result/bridge-detected determinism reading) as a cross-check that +this experiment's re-implementation of ADR-345's methodology is faithful. + +## Production path + +If a future experiment resolves the cut-selection divergence (Next +research #1) in `DirectBuilder`'s favor (i.e., confirms it finds an +equally good or better boundary set, not just a faster one), the next step +would be changing `MincutGatedForgetting::soft`/`::hard`'s default to +`DirectBuilder` and re-attempting ADR-345's bridge-survival hypothesis with +the now-practical latency. Until then, `DirectBuilder` is available but not +default, and `MincutGatedForgetting` overall remains experimental. + +## Falsification criteria + +This experiment's hypothesis would have been falsified by: `DirectBuilder` +failing to show at least an order-of-magnitude latency improvement on the +scaling probe, or showing any non-zero empty-result rate on the +determinism probe, or failing `cargo test`. None occurred. + +## Limitations + +- The <=100x main-benchmark gate is noise-sensitive at this corpus's + absolute latency scale (see "Failure modes" #3) — treat the scaling-probe + and determinism-probe results as the more reliable evidence for the + latency/determinism claim, not the single main-benchmark ratio. +- The cut-selection divergence (bridge survival 50.0%/58.3% vs. 66.7%) is + measured but not explained — this experiment does not know *why* the two + methods disagree, only that they reproducibly do on this one corpus. +- Only one corpus (ADR-345's 84-entry synthetic corpus) and one synthetic + topology (two-clique-plus-bridge, ring k-NN) were used for the + determinism/scaling probes; generalization to other graph shapes or real + embeddings is not established. +- `ruvector-mincut`'s `canonical` feature (genuinely deterministic-by- + construction alternatives) was not exercised. + +## Next research + +1. Investigate the cut-selection divergence using + `canonical::source_anchored::canonical_mincut` (feature `canonical`) as + a third, provably-deterministic reference point, to determine whether + `DirectBuilder`'s or `WrapperPartition`'s cut choice (or neither) matches + the canonical one on the ADR-345 corpus. +2.

I wrote it up, filed the ADR, and moved on, but +left one thread dangling: the slowness was traced to one specific API call, +`RuVectorGraphAnalyzer::from_knn(...).partition()`, and I never checked +whether a *different* call into the same underlying library would avoid it. + +Today I checked. It does — dramatically — and finding out why required +actually reading the slow function's implementation instead of trusting its +name. + +## Technical Design + +`ruvector-mincut` is a general-purpose dynamic minimum-cut library. It +exposes (at least) two ways to ask "what's the minimum cut of this graph": + +- `RuVectorGraphAnalyzer::from_knn(edges).partition()` — a convenience + wrapper purpose-built for exactly the k-NN-graph use case my compaction + policy has. +- `MinCutBuilder::new().with_edges(edges).build()` — a lower-level + constructor for the library's core `DynamicMinCut` structure, meant + (per its module docs) for workloads that need to *incrementally* update a + min-cut as edges come and go. + +I'd used the first one because it looked like the right tool for the job — +literally named for vector-graph integration. Reading its implementation +instead of its name told a different story. `RuVectorGraphAnalyzer:: +partition()` calls into a `MinCutWrapper` that implements a *different* +algorithm than the one `DynamicMinCut` itself uses: it maintains up to 100 +geometrically-scaled "instances," each a full copy of the min-cut problem +tuned to detect a cut in a specific weight range, and on every query it +lazily builds and populates instances — replaying every single edge into +each one — until one of them reports a confident answer. That's a +reasonable design for a system meant to *maintain* a min-cut across a +stream of updates, answering "what's the cut *right now*" cheaply after +the first expensive build. It's a terrible design for what I was actually +doing: building a brand-new graph from scratch and asking for its cut +exactly once, every single compaction call, then throwing the whole +structure away. + +`MinCutBuilder::build()`, by contrast, does the boring thing directly: run +one depth-first spanning-tree construction over the graph, then one +breadth-first pass computing the cut induced by each spanning-tree edge, +and keep the minimum. One pass. No instance replay. No hidden state left +over for a next query that will never come, because I don't have a next +query — I rebuild the graph from scratch every time. + +The fix in code is almost embarrassingly small: a new `BoundaryMethod` enum +with a second variant, and a function that builds the same edge list the +old code already built, feeds it to `MinCutBuilder` instead of +`RuVectorGraphAnalyzer`, and reads the answer back. The interesting part +wasn't the code; it was noticing that "the vector-graph-shaped API" and +"the fast API" were two different things, and that only reading the +library's internals — not its module doc comments, which describe +`DynamicMinCut` as having "O(n^o(1)) amortized update time" without +mentioning that a cold one-shot query pays a very different bill — revealed +which was which. + +## Actual Implementation + +Two real bugs came out of building this, and I'm including both because a +writeup that only shows the version that worked isn't honest about what the +work actually was. + +First: the k-NN neighbor list this code builds stores *cosine distance* +(smaller = more similar), but `RuVectorGraphAnalyzer::from_knn` silently +inverts that to a *weight* (`1/distance`, so near-duplicates get heavy, +hard-to-cut edges) before handing it to the underlying graph. `MinCutBuilder` +does no such inversion — it takes whatever number you give it as the literal +edge weight. My first attempt handed it the raw distance. The result: every +near-duplicate pair (distance close to zero) looked like the *cheapest* +possible thing to cut, exactly backwards from the intended graph structure. +My unit tests — which check that a synthetic bridge vertex with two known +cut edges gets flagged correctly — failed immediately and unambiguously. +Good tests catching a real bug is the system working as designed, not a +setback. + +Second, dumber bug: the k-NN neighbor list is directed (vertex A's neighbor +list can mention vertex B without B's list mentioning A back), but a +plain edge list is undirected, and the underlying graph structure throws an +error if you try to insert the same undirected pair twice. My scaling and +determinism probe scripts — separate small files I use to measure raw +latency and repeatability outside the full compaction pipeline — built +their edge lists without deduplicating by unordered pair, so the very +first duplicate made the whole build fail instantly. This produced a +benchmark reading of "0.0 milliseconds per call, 100% empty result," which +looked suspicious specifically *because* it was too good and too uniform to +be a real timing — a useful reminder that an implausibly clean number is +worth a second look before you write it down as evidence. + +## Actual Benchmark Evidence + +With both bugs fixed, I re-ran the exact scaling probe, determinism probe, +and 84-memory benchmark from the original rejected experiment, changing +only which `ruvector-mincut` API gets called. + +Scaling (ring graph, 19 to 400 vertices, one call each): + +| vertices | old API | new API | speedup | +|---:|---:|---:|---:| +| 19 | 68.4-69.7 seconds | 0.36-0.40ms | ~180,000x | +| 50 | 71-87ms | 1.2-2.0ms | ~45-60x | +| 100 | 410-537ms | 2.8-4.0ms | ~135-145x | +| 200 | 2.4-2.7s | 8.0-29.0ms | ~90-300x | +| 400 | 11.1-11.5s | 21.1-22.4ms | ~510-525x | + +Determinism (fixed 19-vertex graph with one known bridge, 30 repeated calls +on byte-identical input, two separate runs): the old API returned an +unusable empty result 27-50% of the time; the new API never did — 0 empty +results out of 60 calls across both runs, and correctly identified the +bridge vertex in all 60. + +On the original 84-memory compaction benchmark, run six times: the old API +reproduced its own originally-reported 1,800-2,700x slowdown almost exactly +(2,163x-2,800x this time around). The new API landed at 65x-106x — below +the pre-set 100x acceptance bar in most (10 of 12) individual runs, right +at the noisy edge of it in the other two. That noise is worth being +honest about rather than rounding away: the baseline operation here takes +about 30 microseconds, so a ratio against it swings by several multiples +from nothing more than ordinary OS scheduling jitter. The more trustworthy +number is the new API's *absolute* time, which sat in a tight 2.2-3.6 +millisecond band across every single run regardless of what the noisy +baseline did. + +## Limitations + +I did not get a clean, unqualified win. Alongside the speed and +determinism improvement, the new API found a *smaller* set of boundary +vertices than the old one, on this specific corpus, every single time +(50.0% and 58.3% of bridge memories survived, versus 66.7% for the old +API and the plain baseline) — with zero run-to-run variance, unlike the old +API's own flakiness. A minimum cut of a graph isn't always unique, and it +looks like these two algorithms break ties differently, landing on two +different — both technically valid — answers to "what's the cheapest way +to split this graph in two." I don't yet know which answer is "more +correct" for the bridge-protection use case, or whether that even has a +well-defined answer. I'm not flipping the default to the faster method +until I understand that, and I said so explicitly in the follow-up +decision record rather than quietly picking the faster option and hoping +the discrepancy doesn't matter. + +## Production Relevance + +The underlying compaction feature this was built for is still not +recommended for production use — that verdict didn't change today, and +this write-up doesn't claim otherwise. What did change: anyone who *does* +turn that feature on now has a documented, tested, 25-500x-faster, +fully-deterministic alternative available, opt-in, with the slow original +kept as the default so nothing's behavior silently shifts underneath it. +More generally, this is a hardening finding against the underlying min-cut +library itself, independent of my specific compaction policy: any other +caller doing a one-shot "what's the cut of this graph, right now" query — +rather than incrementally maintaining a cut across a stream of edge +updates — is probably hitting the same wall, and has the same fix +available. + +## RuVector Ecosystem Implications + +This is a small, unglamorous result — a follow-up item from a rejected +experiment, closed by reading library internals more carefully than the +first time around — but it's the kind of result the ecosystem's +architecture increasingly needs: cheap, structural, graph-native signals +that anything from agent memory to retrieval to autonomous infrastructure +can call inline rather than schedule as a batch job.

This is reported as a measurement-precision +caveat on the specific inherited gate, not as evidence against the +underlying (very large, very consistent) absolute latency improvement. From 44f7b075c137c148265af013a94162c7faef2f73 Mon Sep 17 00:00:00 2001 From: Claude Date: Tue, 15 Sep 2026 07:50:28 +0000 Subject: [PATCH 4/4] fix(deps): bump rustls 0.23.41 -> 0.23.45 for RUSTSEC-2026-0285 The Security audit CI check (cargo audit) started failing on this PR after RUSTSEC-2026-0285 (TLS 1.3 handshake messages incorrectly accepted across encryption level boundaries) was published against rustls 0.23.41, one day before this PR was opened. Confirmed this is not caused by this PR's diff: Cargo.lock was byte-identical to main before this commit, and main's own last supply-chain audit run predates the advisory. `cargo update -p rustls --precise 0.23.45` (and its rustls-webpki dependency) via cargo's own tooling clears the vulnerability; `cargo audit` now exits 0 (only the 3 pre-existing allowed warnings remain, as before). No source code depends on rustls directly; ruvector-agent-memory's tests remain green against the updated lockfile.
