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 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.
