ogar-r2il: wire PUSHES into segmentation; counterfactual visibility ladder probe (D-CFW-LADDER) - #289

Conversation
`ogar_vocab::ConceptDomain::Ontology` carries zero shared codebook rows by design, so a consumer that reaches for `concepts_in_domain(Ontology)` gets an empty set — and an empty set reads exactly like "there is nothing here to reason about". There is; it lives here, deliberately, so ERP and project consumers never compile it. What was missing was a way to ASK. Without an enumeration a consumer has three options and all three are bad: repeat the list locally (which `from_concept_id`'s own doc already warns about, after the 2026-08-13 crosswalk audit found that inverse hand-written downstream), scan all 256 slots of the block, or compute the ids from the variant order. The third is the one that was actually found downstream: `0x0300 | (ns as u32 + 1)` is right only because five variants happen to be declared in the same order as five contiguous ids, and it invents a `0x0306` for any ordinal past the end. `ALL` is ordered by `concept_id`, so a caller iterating it walks the block in address order. The guard is the point. An array literal is not a match, so the compiler will force a sixth namespace into `prefix` / `concept_id` / `from_concept_id` and say nothing about the array. The test therefore does not compare against a second hand-written list: it sweeps the entire u16 space, collects everything `from_concept_id` resolves, and asserts that set is exactly `ALL`'s, in both directions, with the anti-vacuity check that the sweep really is selective (5 of 65536). Verified by mutation — teaching `from_concept_id` a sixth id without extending `ALL` fires it with that message. 48 tests green, clippy -D warnings exit 0, fmt clean.
Operator ruling 2026-08-22: "the domains should be minted in ogar-vocab". This reverses the 0x03XX block's "ZERO vocabulary rows BY DESIGN … Do NOT mint rows here" — reversed in place with its reasoning intact, not deleted. It was plug-and-play: only a consumer deping ogar-obo compiled the OBO concepts, so ERP / project consumers never pulled them into their concept space. It also produced three things: 1. `concepts_in_domain(ConceptDomain::Ontology)` returned an EMPTY set, and an empty set is indistinguishable from "this domain has nothing to reason about". That is how it was read — in this session, by me, in writing, before the code was checked. 2. The domain had THREE independent mint sites and no enumeration spanning them: registry::OBO_CORE (0x0301..0x0305), registry::META_STUDY_SPINE (0x0340..0x0347) and ogar_ro::RELATION_BODY_CONCEPT_ID (0x0306). META_STUDY_SPINE was once minted OVER 0x0306 and nothing failed; the collision was found by hand-enumerating during an unrelated audit. The guard that catches it now lives in ogar-ro, the only crate that can see both sides — but a guard per pair does not scale and cannot see a site nobody added. 3. With no enumeration to call, a consumer computed the ids instead: `0x0300 | (ns + 1)`, correct only because five variants happen to be declared in the order of five contiguous ids — and yielding 0x0306, i.e. ogar-ro's relation body, for any ordinal past the end. One mint site makes (2) structurally impossible — codebook_has_no_duplicate_ ids_or_zero now covers the whole domain in one table — and (1) and (3) stop being reachable, because there is something to ask. 14 concepts, promoted as ATTRIBUTE-FREE reference classes, the same shape the 0x04XX weather cells use. An OBO namespace's content is terms and edges and those live in the bake; asserting attributes here would be inventing a model for data this crate does not own. The mint records IDENTITY, which is the thing that has to be collision-free. Three-way pinned as the architecture requires: CODEBOOK ⟷ class_ids::ALL ⟷ all_promoted_classes(), plus the two count pins (93 → 107). The paired mirror half is in lance-graph (contract ogar_codebook), same arc — hotplug's mirror_disagreement is what would have caught it missing. The producers keep their typed surfaces; ALL is the enumeration ogar-obo was missing. Its scope is stated precisely — OBO_CORE only, NOT the 0x03 domain, which also holds META_STUDY_SPINE and ogar-ro's slot in a crate ogar-obo cannot see (the dependency runs ogar-ro → ogar-obo). Iterating ALL and calling it "the ontology" would miss nine of fourteen. It is not a new copy: registry::tests::obo_core_matches_the_shipped_enum already carried that exact array as a local literal and now consumes the public const, so three copies of the list become two — and the agreement between those two is what that test asserts. Guard: all_is_exactly_the_set_from_concept_id_resolves sweeps the whole u16 space rather than comparing against a second hand-written list, because an array literal is not a match and the compiler will not force a sixth namespace into it. Verified by mutation — teaching from_concept_id a sixth id without extending ALL fires it. 157 ogar-vocab tests, 48 ogar-obo, 10 ogar-ro; clippy -D warnings exit 0, fmt clean.
…adder probe Two things, found in one motion: 1. Crate fix: R2ILVocabulary shipped the PUSHES column and an inherent pushes_result but never answered Vocabulary::domain_pushes_result, so ogar_loco::statement_bounds refused every R2IL call as Uncovered -- R2IL bodies were lowerable but not segmentable. The override now delegates to the table; test pair proves an R2IL store idiom segments and a variadic op stays refused. 2. Probe (D-CFW-LADDER, ledger entry appended): witness streams derived from a real FunctionBody with the loco statement as the Markov window and counterfactuals as statement-local semantic edits confined under CallMask/project. Four-rung visibility ladder measured: byte sees all three edit classes; exact areas see both dataflow edits; the register cast sees only midpoint-crossing dataflow edits (its 1-bit orientation is midpoint-granular -- first gate expected more and was falsified); increments are provably blind to every pure reordering. Rule substitution within a locus class reaches no stream tier. Verified against the #288 inline-words CallMask (branch merged with main before landing). 13 lib tests green; probe GREEN G0-G4.

This newly added API documentation contradicts the same commit's ogar-vocab changes: CODEBOOK now contains 14 0x03XX rows, so concepts_in_domain(ConceptDomain::Ontology) returns those rows rather than an empty set. A consumer following this guidance may unnecessarily assemble three producer-specific enumerations or treat Namespace::ALL as the only available discovery surface; update the explanation to distinguish this five-namespace typed subset from the new shared 14-row domain enumeration.

Correct the CF-2 direction in the header.
The header states CF-2 substitutes IntAdd → IntSub. The code does the opposite: s_star selects a statement whose consumer is IntSub (line 381), and line 400 replaces it with arith[0], which is IntAdd. Line 398 and the G3 label at line 458 both say IntSub → IntAdd.

Addresses the #289 review round + the red CI, all inherited from the branch's 2026-08-22 mint commit landing without its consumers: - CI red (ogar-class-view): the mint promoted 14 0x03XX rows into CODEBOOK but never registered them in all_canonical_classes(), so the codebook<->registry gates failed on exactly the drift they exist to catch (mondo 0x0301 missing; iteration-order pin broken). The 14 factories already existed in ogar-vocab; they are now registered in codebook order. 12/12 class-view tests green; full workspace check + test green (84 suites). - codex P2 + coderabbit (ogar-obo): the Namespace::ALL doc still said the Ontology domain carries zero shared codebook rows by design — the mint reversed that ruling, so concepts_in_domain(Ontology) now returns the full 14-row domain. Doc corrected in place with the reversal noted: the shared codebook is the domain discovery surface; Namespace::ALL remains the typed five-namespace OBO_CORE subset. - coderabbit (probe header): CF-2 direction corrected (IntSub -> IntAdd, matching the code); header lifted from the pre-amendment three-tier/G2 wording to the executed four-tier ladder with G2a/G2b and the named midpoint blind spot.

What
Replaces the mechanical-dummy counterfactual measurement with the wired loco/r2il thinking surface, and fixes a real gap the wiring exposed on first contact. Carries the two pre-existing unmerged branch commits (ogar-vocab Ontology mints + ogar-obo
Namespace::ALL) and is merged with main (#288's inline-wordsCallMask), verified against it.1. Crate fix — R2IL bodies were lowerable but NOT segmentable
R2ILVocabularyships thePUSHEScolumn and a pub inherentpushes_result, but never answered theVocabulary::domain_pushes_resulttrait hook thatogar_loco::statement_boundsactually reads — so segmentation refused every R2IL call asUncovered(first observed asUncovered(IntAdd)). The override now delegates to the table. Test pair: an R2IL store idiom (NUMBER NUMBER IntAdd NUMBER Store) segments into one 5-call statement; a variadic op (CallOther) stays refused (arityNoneshort-circuits first). 13 lib tests green.2. Probe — the four-rung counterfactual visibility ladder (ledger: D-CFW-LADDER)
crates/ogar-r2il/examples/probe_counterfactual_witness_kernel.rs:FunctionBody, mixed shared-core + domain calls underR2ILVocabulary.statement_bounds, the R5 maskable unit) — intra-window order is the stack discipline, not noise.CallMaskthe factual and edited slabs project identically; inside they differ.Measured (G0 anchor 8.0e-5 vs the I₀(2√⟨u,v⟩) closed form):
Ladder: byte ⊇ exact-area ⊇ register ⊇ increment. Increments are provably blind to every pure reordering; the register cast is a detection instrument for dataflow-order interventions at or above statement-midpoint scale; rule substitutions within a locus class reach no stream tier — the byte tier (the program itself) is the floor. The probe's own first G2 gate expected the register to see the intra-run swap and was falsified — the amendment is documented in-file, and the blind spot is named in the ledger rather than hidden.
