From 6fa62b8d8b491f9b8716dcd0e9a07611136f594c Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 29 Jul 2026 14:22:32 +0000 Subject: [PATCH 01/14] refactor(meta_basin): migrate the 7 gathered window params onto the zero-copy lens MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The `window: &[(usize, CausalWitnessFacet)]` family in `nars/meta_basin.rs` required a caller to walk `NodeRow`s and copy each row's 12-byte register into a packed `Vec` — a second stored projection of bytes that already have one. All 7 now take `(&WitnessLens<'_>, &impl Fn(usize) -> bool)` and read registers through a bounds-checked cast into each row's own value slab. Migrated IN PLACE: no twins, no deprecation window. The family has zero callers outside its own file — confirmed structurally, not by grep alone: the lib compiled clean while only the in-file test module broke, across 21 call sites. The lens-migration card requires the materializing path to be GONE rather than merely unused, and here nothing external forces it to be kept. Sparsity is the part that made this more than a signature swap. `resolve_chain` walks hops by absolute stream POSITION, so a gathered window could name positions [0,1,2, 10,11,12, 20,21,22,23] with no rows between them. A lens indexes a dense row array, so the gaps must exist as rows and be excluded by `visible`. Every fixture was rebuilt around `rows_from` + `vis_of` rather than re-called. Proof: the pre-migration body is retained verbatim as the `grade_rows_gathered` oracle and compared field-by-field across 6 hop budgets x 2 fixtures, plus `an_invisible_gap_is_excluded_even_though_the_row_exists`, which pins that the skipped row EXISTS and is addressable while being invisible. The equivalence test passed on two successive fixtures while the run still failed, both times on the per-axis anti-vacuity clause: every row graded quorum = 0, first because a sparse window has no quorum by construction, then because `quorum_mantissa` rounds agreed*15/(peers*14) DOWN so one agreeing locus floors to zero. The equality assert cannot see this — constant-vs-constant is the most reliably passing comparison there is. The dense fixture now agrees on four loci, a number derived from the formula rather than guessed. Revert-test: deleting the `visible` filter fails 3 tests, including "sparse: row count diverged at max_hops=0". Gates: cargo test -p lance-graph-planner 324 + 4 passed / 0 failed; clippy --all-targets -- -D warnings clean; cargo fmt --check clean.

Checking properly turned up a standing gap. `lance-graph-osint` is workspace-excluded, so no workspace command reaches it and no workflow names it via --manifest-path. `cognitive-shader-driver` is a member, but its planner dep sits behind an optional `with-planner` feature that no workflow enables. Neither is built by any CI job, so a breaking change to a planner API can pass every gate and break them on the next local build. Both verified clean by hand for #868, which is precisely why it is filed: a manual check does not survive contact with the next session.

Counted with a `visible` closure rather than wall-clock (deterministic, and it measures the algorithm instead of the runner): 4608 probes at N=512/k=8 against 64 peer comparisons for the gathered form. The trade is two-sided, which the review did not mention: gathered `resolve_chain` resolved every hop with a linear `position(..)` scan, so hop work goes Theta(hops*k) -> Theta(hops) under the lens. Net per row is `k*(1+hops)` gathered vs `N+hops` lensed; the lens wins on dense windows and deep chains, loses on a small window over a large row array. `grading_cost_scales_with_lens_length_not_window_size` pins that shape both ways: it asserts the sweep happens AND that cost is not superlinear in N, so a later improvement fails the test deliberately instead of passing unnoticed. Operator ruling recorded on the debt entry: the fix is neither a lifetime parameter nor a caller-narrowed lens. A window carries ADDRESSES, not data — the corpus already exists, positions are the hard facts, facets resolve at read time. That removes the borrow that made `WitnessWindow` look like it needed a lifetime on `PlanContext`, and it bounds the peer domain by k instead of N. The BLOCKED item and this P2 were the same problem seen from two sides.

Copy on a borrow-carrying type is the violation — a Copy borrow duplicates itself silently, so it can be stored beside the original and carried out of the compartment that owns the bytes with no move and nothing in a diff to point at. Copy on a small owned value is the opposite: data-flow.md section 2 REQUIRES it for reasoning microcopies (TruthValue, Fingerprint, u64, Band, CpuCaps, ScanParams), so a blanket removal would break the rule from the other side. The Tier A/B split was produced by a crude heuristic (lifetime parameter, or a field spelled &) and I expect false positives in it — several Tier A rows show no lifetime in the declaration and were likely flagged on a &'static or a doc-comment. Seven agents are auditing it per-site; their brief says to overturn the classification rather than confirm it. Already fixed and absent from the list: WitnessLens<'a> (b3515ba).

eba7ed6bdd7a7b51e38f88023ec5bf0c9419d968 Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 29 Jul 2026 15:13:45 +0000 Subject: [PATCH 06/14] refactor: drop Copy from borrow-carrying types; 7-agent census of 369 derive sites MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Operator order: "copies are forbidden, borrows are only for the same mailbox"; "WitnessLens is forbidden as a copy. period"; "only cognitive achievements > tenant". A `Copy` borrow duplicates itself silently: it can be stored beside the original and carried out of the compartment that owns the bytes, with no move and nothing in a diff to point at. That is how a same-mailbox borrow escapes its mailbox. Census first, because the earlier count in this session (26) was wrong -- it grepped one literal spelling on one line. The real figure is 369 sites across both orderings, logged at .claude/board/exec-runs/copy-derive-blast-radius.txt. This is NOT a blanket removal, and could not be: .claude/rules/data-flow.md §2 REQUIRES `Copy` on reasoning microcopies (TruthValue, Fingerprint, u64, Band, CpuCaps, ScanParams -- passed by value, no heap, no lifetime tracking). Removing those breaks the rule from the other side. Seven agents therefore gave a verdict per site rather than sweeping: 24 VIOLATION, 26 LEGITIMATE, 13 ELEVATED (a value at a strictly higher rung than every input it derives from, which earns its store). Eight derives changed here; the remaining violations were reported as cascades the agents were instructed to describe rather than perform, so the shape is visible before anything moves. Central gates (I compile once, the fleet edits only): - cargo test -p lance-graph-contract -p lance-graph-planner -p lance-graph-callcenter --lib -> 1134 + 325 + 156 passed, 0 failed - cargo check on lance-graph-cognitive and deepnsm -> clean - cargo fmt --check -> clean Two pre-existing breaks surfaced, both verified NOT caused by this change and both in crates no CI job builds or lints: - holograph lib-test fails at mindmap.rs:869 (needs `mut`); identical failure with the agent edit stashed. - 13 clippy errors in lance-graph-ontology (deprecated oxrdf::Subject alias, doc-list indentation), reached only because callcenter deps it. These extend TD-PLANNER-DEPENDENTS-NO-CI-BUILD: the per-crate CI is narrower than the dependency graph in more places than that entry named.

The repair is +`repr(C)` (or a `[u8;12]` newtype) + a `ref_from_bytes`, which is a design change +well past "remove a derive," so I left it. Removing `Copy` here would be the +worst of both: it forbids the microcopy without creating the lens. +Also note `L4Tenant` has **zero consumers outside its own module tree** — +adjacent to the law's *"a type whose only constructors are `#[cfg(test)]` is a +shadow of storage"* clause. Worth a producer check before it grows. + +**F2 — `bgz17/src/scope.rs:31-45` `Bgz17Scope` stores THREE per-edge lanes over +the same edges** (`scent: Vec`, `palette_indices: Vec`, +`base_patterns: Vec`). By the letter of *"a projection is never +stored"* this is three stored readings of one content. **I did not rule on it, +because ruling would decide an architecture question above my brief:** this is +the certified HHTL precision ladder (`Precision::{Scent, Palette, Base, Exact}`, +`bgz17/src/lib.rs:78`; the atlas chain in `encoding-ecosystem.md` with measured +ρ = 0.937 / 0.965 / 0.992). Each rung is *lossy* relative to the one above, so +no cast reproduces a coarse lane from a fine one, and the coarse lane exists +precisely to avoid reading the fine one. Two readings are available and they +disagree: **(a)** a lossy coarsening is the same awareness stage at lower +resolution → "never stored"; **(b)** `scent` here is computed against the +**scope centroid** (`scope.rs:79-88`), making it population-relative and thus +elevation-shaped, not a pure coarsening. This is a live tension between the +zero-copy law and a FINDING-graded certified cascade, and it deserves an +operator ruling, not a subagent's edit. No `Copy` derive causes it — the `Vec` +fields do. + +## Coordination note + +`copy-tierA` and I overlapped on exactly one file. The shared checkout has no +lease, so the only thing that prevented a lost write was re-reading the file +before editing.

VIOLATION — `AuditChain`, `lance-graph-callcenter/src/unified_audit.rs:196` + +`#[derive(Clone, Copy, Debug)]` → `#[derive(Clone, Debug)]`. + +The strongest finding of the run. `AuditChain` is single-writer chain state +(`advance(&mut self)` writes `self.last_root`), and `last_root` is a second +holding of a root **already durably recorded** on the last emitted event. A +`Copy` silently forks the chain: two advancers stamping distinct events as +successors of the same `prev_merkle` — which is precisely the tamper signature +`verify_chain` exists to detect, minted by the type system with nothing in a +diff to point at. §13.4's cross-domain unlinkability rests on one salt, one +root, one writer. + +The correct shape is already present structurally and the derive was +undermining it: `UnifiedBridge` holds `Mutex` (one-writer mailbox) +and the sanctioned way to continue a chain elsewhere is +`AuditChain::resume(.., last_root)`, which is *explicit about which root it +claims*. + +Cascade: **none.** All uses are `AuditChain::new` / `::resume` / +`Mutex::new` / `&mut` `advance` through the lock; `audit_root()` copies out +`last_root` (an `AuditMerkleRoot` u64 — untouched). `Clone` retained +deliberately: it forks too, but an explicit `.clone()` is greppable and +nothing calls it today. **Follow-up worth an operator call: `Clone` on a +merkle advancer is arguably also forbidden** — I did not remove it because +that exceeds the stated scope (the census targets `Copy`). + +## The `'static` verdict (why the 4 Tier-A callcenter entries are NOT violations) + +`FamilyEntry` (`family_table.rs:132`), `OwlPivot` (`odoo_alignment.rs:65`), +`MetaAnchors` (`super_domain.rs:125`), `SuperDomainEntry` (`super_domain.rs:181`) +were flagged for `&'static str` / `&'static [u8]` / `&'static [OgitFamily]`. + +**A `'static` borrow has no mailbox to escape.** It borrows immutable rodata +that outlives every compartment and has no writer, so it can neither dangle +nor drift. And `Copy` on a struct of `&'static` fields duplicates **pointers, +not content** — the grey/white fence in `zero-copy-lens-law.md`: *"cross-tenant +pointers are legitimate; cross-tenant values are not."* These rows are the +already-correct shape; forcing them to own their strings would be the +violation. Same verdict covers ontology's ~30 `odoo_blueprint` baked rows — +`OdooEntityPairing` holds `&'static OdooEntity`, the reference-not-copy shape +done right. + +## ELEVATED — the audit-event question, answered + +The operator asked whether `UnifiedAuditEvent` / `AuditChain` / +`AuditMerkleRoot` are higher-rung achievements or copies of something already +recorded. They split three ways, which is the interesting part: + +- **`AuditMerkleRoot` (`:94`) — ELEVATED.** `chain(prev_root, salt, bytes)` is + a **cross-term**: a computation across multiple reads yielding a value of a + different KIND — a fact about the *sequence*, not a member of it. It is + reproducible by no cast from any lane. This is exactly the Gadamer-refined + test in `zero-copy-lens-law.md` and the shape of the shipped + `Locus::Quorum` / `Contradiction` precedent.

Storing is legitimate — that IS the + calcification. `Copy` kept (a `u64`). +- **`UnifiedAuditEvent` (`:135`) — ELEVATED, keep `Copy`.** Its input fields + (tenant/owl/op/role-hash) do each exist elsewhere, so field-by-field it + looks like a copy — but the event *as emitted* carries `merkle_root` + + `prev_merkle`, so the row is the elevation, not a gathered view of the + request. It is **immutable once stamped**, so a copy cannot drift; 42 bytes + of scalars, no borrow. The doc-comment's stated reason for hashing the role + rather than storing `&'static str` ("so the event is `Copy` + fixed-size") + is a durability argument, and it holds. +- **`AuditChain` (`:196`) — VIOLATION.** Not the witness; the *advancer*.

A value.** +Your question was the right one to ask. `#[repr(C)]`, a `SIZE` const, a `≤24 B` +test — the author is clearly thinking in bytes. But it is not a record *of bytes +that already have a lens*: `from_thought(…)` takes computed `f32`s from the +cascade and **quantizes them** (`dissonance * 255.0 as u8`, `top3` from a slice, +`gate` from a match). The inputs are transient computation outputs, not lane +bytes, and the DTO is the only stored form — it lives as `A2APayload::Thought(FastBusDto)` +on an `A2AMessage`. It crosses an **agent** boundary, not a tenant boundary, and +your own rule (*"borrows are only for the same mailbox"*) is exactly why an owned +value is the correct shape there: removing `Copy` pushes toward a reference, the +forbidden direction. **Standing watch, not a finding:** if a SoA lane ever holds +these same 12 fields, `FastBusDto` becomes the second projection that day. + +**`thinking-engine/src/layered.rs:45 CascadeChannels8` — LEGITIMATE.** +`pub struct CascadeChannels8(pub u64)` — a newtype over one `u64`, 8 signed byte +channels read by shift+mask. `u64` is in `data-flow.md` §2's list by name. It is +not a second projection: it is the **accumulator during L1→L2→L3 propagation**, +and it is *transcoded* into `causal_edge::CausalEdge64` at the L3 commit boundary +(the impl block says so), never stored beside it. Converted, not duplicated. The +one field holding it (`domino.rs:90 pub edge: CascadeChannels8`) owns it outright +— there is no lane backing those bytes. + +**`jc/src/ewa_sandwich.rs:104 Spd2` — LEGITIMATE, and `Copy` is load-bearing.** +3×`f64` = 24 B.

Removing `Copy` forces +in-place `&mut` mutation of `sigma`, i.e. the P0 in the other direction. Same +verdict for the identical `Spd2` in `koestenberger.rs:99`, `Spd3` in +`ewa_sandwich_3d.rs:99`, `Sym2` in `sigma_codebook_probe.rs:77`, and the three +`Mat2` copies in jc examples. + +**`jc/src/ewa_sandwich.rs:232 PathResult` — LEGITIMATE, with an elevation note.** +`{ final_sigma: Spd2, log_norm_sq: f64, psd_hops: usize }`. `final_sigma` is a +member (same rung as its inputs); `log_norm_sq` and `psd_hops` are **facts about +the set of hops, not members of it** — the Gadamer-refinement shape that *would* +be elevation-eligible. But the rung test is not triggered, because **nothing here +is stored**: `propagate_path` returns it to a local. Same for +`ewa_sandwich_3d.rs:384`. + +## ELEVATED — I am claiming this verdict for nothing, and here is why + +The rubric licenses a store.

That is a computation across many reads yielding a value of a + different KIND (a node's neighbourhood permeability, which lives in no single + coupling) — not reproducible by a cast. Today it is returned, not stored. The + module doc already describes it as *"the BF16 residue … a helix-residue value + slot on the HHTL-OGAR key"*, and `columns.rs:136 INERTIA_PROMOTION` records a + `RatifiedReuse` verdict promoting it into a `ResidueEdge` slot. **So the store + is planned.** When it lands it needs the rung named explicitly, per the law's + one-exception test — it should not inherit "it was already a `Copy` struct" as + its licence. + +--- + +## Changes: none.

A `Copy` packet is a silently duplicable second holder of one + mailbox's whole store. Comment says exactly that. +2. **`bitpack.rs:552` `VectorSlice<'a>`** — the archetypal lens, and the file's + own doc-comment already argues the zero-copy case at length ("copies 0 bytes + for the 999,000 that fail the cascade"). The `Copy` derive was the hole in + that argument: `as_words(&self) -> &'a [u64]` re-exports the borrow at the + full `'a`, so a duplicated slice outlives every scope visible at the call + site. +3. **`homograph_collapse.rs:63` `Collapse<'a>`** — smallest, and I did NOT + downgrade it for that. Size is not a mitigation under this law. + +## What broke at the call sites: **nothing, on inspection.** + +I traced every construction and consumption of the three types. This is a +static read, not a compile — the central build is yours. + +- **`NodeRowPacket`** — 12 sites (`symbiont/src/bridge.rs:129`, + `contract/src/ocr.rs:211`, 10 in-file tests, re-export in `lib.rs:190`). + Every one is `let pkt = NodeRowPacket::new(&rows, c);` followed by `&self` + methods (`n_rows`, `cycle`, `as_le_bytes`, `row_le`, `verify_layout`) or the + associated-const path ` as SoaEnvelope>::LAYOUT_VERSION`. + No by-value pass, no field storage, no `.clone()`. **`SoaEnvelope` declares no + `Copy`/`Clone` supertrait bound** (`soa_envelope.rs:170`), so the impl is + unaffected. +- **`VectorSlice`** — `storage.rs` (`get_slice`, `cascaded_knn`, + `from_bytes_or_copy` at :797), `navigator.rs` (`ZeroCopyCursor::next`), + `hamming.rs`, plus 4 tests. Every consumer takes `&dyn VectorRef` or + `&slice`. The one move is `return Some((id, slice, stacked.total))` in + `ZeroCopyCursor::next` — a genuine move *after* both borrows have ended, which + is fine without `Copy`. **`VectorRef` declares no `Copy`/`Clone` bound**, and + there are no by-value operator impls for `VectorSlice` (the `BitXor`/`BitAnd`/ + `BitOr`/`Not` impls at `bitpack.rs:696-730` are all on `BitpackedVector`). + Note `ZeroCopyCursor.query` is `&'a BitpackedVector`, not a `VectorSlice` — it + was the one field that would have forced a cascade, and it does not. +- **`Collapse`** — 6 sites, all in-file. The only by-value use is + `if let (Collapse::Unique(_, pr), Collapse::Unique(_, sr)) = (p, so)` at :157, + which moves `p`/`so` into a tuple and never touches them again. Legal. + +**No cascade found, so none refused.** If the central build disagrees, the most +likely single point is a `.clone()` I did not spot on `VectorSlice` inside a +`datafusion-storage`-gated block — `holograph/src/navigator.rs` and +`storage.rs` are partly behind that feature, and my read covered the gated code +textually but a feature-off build never type-checks it either way. + +--- + +## One phrasing note (NOT an edit, but you should see it) + +`crates/lance-graph-contract/src/mul.rs:229-230`, on `MulThresholdProfile`: + +> *"The struct is `Copy` so it can sit on the BindSpace per-row carrier +> **without indirection**."* + +That is one clause away from the trapped formulation the warden card lists +verbatim ("12 B inline beats a 16 B pointer plus indirection"), and +`zero-copy-lens-law.md` § "Projection is not chasing" rules the indirection term +**zero in this substrate**. I did not edit it, for two reasons I want on the +record rather than assumed: + +1. The type is a §2 microcopy (3 `f32` + a `&'static str` label) and `Copy` on + it is required, not merely allowed — so the *conclusion* is right even though + the *argument* is one of the trapped ones. +2. The sentence describes a hypothetical ("so it **can** sit on"). Today + `for_context(id)` is a `const fn` returning a value; nothing stores a profile + in a per-row lane. + +**But if that hypothetical is ever built, it is a violation**, and the doc +already pre-argues for it: the profile is a pure `const fn` of +`ontology_context_id`, so a per-row profile lane would be a projection of a lane +that already exists — `output_rung == max(input_rungs)`, no elevation. Worth a +line in the law's cost-argument catalogue as a live in-tree instance; your call +whether that is this task's business. + +## Honest limits of this run + +- Verdicts are from reading the type definitions and every call site, not from + a compiler.

It was not. This removes the allocations that were actually on the compute path. - `grade_rows` returned `Vec`; it is now a lazy iterator. Grading is a projection over addresses -- there is nothing to accumulate. - `tail` took `&[GradedRow]` and `.copied().collect()`ed into a SECOND Vec. It now consumes the grading iterator directly, so the chain allocates ONCE, at the clustering boundary where `meta_cluster`/`density_scores` genuinely need random access. - `stable_under_perturbation` rebuilt a full `Vec` inline per probe, and `stability_sweep` calls it once per budget -- 11 allocations per basin on the default range. It now calls `grade_shapes_at`, which is lazy AND skips the quorum sweep entirely: `meta_cluster` reads only `.trajectory`, so the expensive half was being computed and thrown away on every probe. Net on the sweep path: two Vec allocations per graded row collapse to one, and the per-budget re-grading stops computing a quorum nothing reads. Also drops a redundant `#[must_use]` (the returned iterator already carries it).

The point worth keeping is that none of the three was a trade. In each case the copy was an artefact of how the code was written rather than of what it had to compute -- a collect between two already-fused loops; a filter that reallocated what it filtered; an inline rebuild that obscured which half of the work was dead. So removal costs nothing and buys something: - grade_rows: lazy, so a consumer that short-circuits (tail filters on quorum) no longer pays to fully grade rows it never reaches. - tail: takes IntoIterator instead of &[T], so the filter fuses into the grading -- one pass and one allocation where there were two of each -- and it is strictly more general, since slices still satisfy the bound. - stable_under_perturbation: naming the operation `grade_shapes_at` exposed that meta_cluster reads only .trajectory. The inline version already knew (it hardcoded quorum: 0) but the general grade_rows beside it did not. Per basin per sweep this deletes 11 allocations AND 11 full quorum passes. The copy was not the cost; the copy was hiding the cost. That is the operator's ruling made concrete: "a materialization is strictly worse on both axes" was literally true here -- the copies were slower and they concealed a dead computation running 11 times per basin.

No +`Copy`, no clone, no owned capture — the iterator is a *description* of work +over borrowed state, which is exactly the lens argument one level up. + +### 8.2 `tail` — the copy was a filter that reallocated + +**Before.** `tail(graded: &[GradedRow], …) -> Vec` doing +`.iter().copied().filter(..).collect()` — a full second buffer, from a buffer +built one line earlier. + +**After.** `tail(graded: impl IntoIterator, …) -> Vec`. + +**Why better.** Taking `IntoIterator` instead of `&[T]` means the filter fuses +into the grading iterator: **one pass, one allocation, for what was two of each.** +And it is strictly more general — a slice still satisfies `IntoIterator`, so +nothing that could call it before cannot call it now. The remaining `Vec` is +kept deliberately: `meta_cluster` and `density_scores` need random access, and +an accumulation that a real algorithm requires is not a copy in the sense the +law forbids. + +### 8.3 `stable_under_perturbation` — the copy hid a computation nobody read + +This is the one that produced a genuine algorithmic win rather than an +allocation win. + +**Before.** Inline, per probe: +``` +let reperturbed: Vec = (0..lens.len()).filter(visible).enumerate() + .map(|(idx,pos)| GradedRow { idx, pos, quorum: 0, trajectory: … }).collect(); +``` + +**After.** `grade_shapes_at(lens, visible, locus, hops).collect()` — a named, +lazy, shape-only grading. + +**Why better.** Naming the operation exposed what the inline version obscured: +`meta_cluster` reads **only `.trajectory`**. The inline code already knew this — +it hardcoded `quorum: 0` — but the *general* `grade_rows` next to it did not, +and `stability_sweep` calls this **once per budget**, 11 times on the default +range.

Real, and no test caught it because every fixture builds from position 0, so the one distinction that matters was constant across every comparison in the suite. My first fix added a `base` offset so sliced lenses would address correctly. That was wrong-headed: it makes slicing SUPPORTED. The standing wave is a single ~16 MB array (32k rows x 512 B) and is lensed whole -- a sub-slice is not a narrowing, it is the error. Reverted, and the invariant is now stated on the constructor instead, including an explicit "do not fix this by adding a base offset" so the next reader does not repeat it. This also reorders the remaining work. At whole-corpus scale `quorum_mantissa_lens` scanning 0..lens.len() per focal is ~32k probes per graded row, and it is fatal precisely BECAUSE the lens spans everything. Expressing the window as a predicate over the corpus rather than as the addresses already in hand is the single root cause behind both Codex's symptom and TD-LENS-QUORUM-SCANS-THE-WHOLE-LENS; narrowing belongs in the caller's address set, never in where the array starts.

The 369 pass even asserted "this census matches both orderings" -- a claim about the fix I had just made, not about what the regex could see. CodeRabbit caught it by cross-checking the agents' own tag files (119/95/123 vs the 56/73/70 recorded). That is the check I should have run myself: a second independent source was already in the repo and I never compared against it. Also corrects the ontology carve-out, which cited 13 sites; it is 45. The undercount had propagated into a scope exclusion, which is the worse failure -- a carve-out sized by a broken count silently under-protects.
