feat(v3): T-Numeric-Construction S9 Slice 2.5 — predicate registry + PB-1 shim retirement by briansrls · Pull Request #1846 · gunb-ai/gunbc

Summary

S9 Slice 2.5 Path 3 RATIFIED at gunbc#828 issuecomment-4390333451 (Director, post proud-lynx-311 pre-flight DFS at gunbc#1746 issuecomment-4390253616). Five deliverables landed in single bundled PR per Director ratification.

What lands

gt_zero primitive predicate enrolled in registry (Nat-defined per Director Option 2 ratification at gunbc#828 issuecomment-4390199218). gt_zero IS the reason for "Nat without zero" / "Nat above structural bound"; range(min: 1) over Int was a misleading label that treated Nat's lower-bound = 0 as a contingent rather than structural fact.
KNOWN_PREDICATE_REGISTRY substrate-fact-introduction in src/v3/compiler/src/lower.rs — authoritative set of predicate identifiers recognized by where-sugar refinements: range, pattern, non_empty, brand, format, content, gt_zero. Sole authority for predicate-name resolution; no parallel paths.
PB-1 shim retired: prior file-path special case span.file == "dsl/std/types.dag" in lower_type_alias_refinements_phase replaced with registry-name dispatch via all_predicate_names_registered. Per feedback_no_textual_enforcement_bridges, gating structural behavior on a textual file identifier was the anti-pattern; registry-name dispatch is the substrate-faithful authority. alloc_deferred_types_dag_refinement_placeholder renamed to alloc_registered_refinement_placeholder (file-name dropped from placeholder name string).
Existing dsl/std/types.dag predicates migrate cleanly through the registry; bootstrap snapshot + parse-corpus manifest hold (no semantic drift). Cascade-clearance verified: every range/pattern/non_empty/brand/format/content declaration in types.dag continues to resolve correctly post-shim-retirement.
PositiveInt = Nat where gt_zero migrated to dsl/std/integer.dag (companion to NonNegativeInt = Nat from feat(std): T-Numeric-Construction S9 Slice 2 (partial) — NonNegativeInt = Nat #1840). src/v3/std/approximate_field.dag consumer updated to import std.integer { PositiveInt }.

Hard scope bars (Director ratification at gunbc#828 `issuecomment-4390333451`)

✅ No parallel predicate-resolution path: registry is the sole authority post-landing.
✅ No per-call-site predicate special-casing: registry-name dispatch is name-based, not file-path / declaration-name dispatch.
✅ PB-1 shim retirement non-negotiable in same slice: file-path special case fully removed; replaced inline with the registry check.
✅ Cascade-clearance verification: bootstrap snapshot + parse-corpus manifest hold; failing test p0_std_render_repeat_string_test (which surfaced Slice 2 Gap 2) now passes.

DFS-of-concept-DAG receipt (P1 substrate-fact-introduction)

gt_zero did NOT exist anywhere in dsl/std/, src/v3/, or Rust source pre-PR (per pre-flight DFS at gunbc#1746 issuecomment-4390253616).
Predicate registry did NOT exist as substrate-fact-introduction; this PR IS the landing.
PB-1 shim existed at lower.rs:821-835 (lower_type_alias_refinements_phase) — retired here.

Implementation note — placeholder-name matcher

The is_deferred_refinement_placeholder helper (used by scalar_literal_requires_refinement_discharge to skip discharge for placeholder refinements) string-matched against the OLD placeholder name format "<std/types.dag: \where` parsed, predicate not lowered: …>". Updated to match the NEW format "<registered predicate, body not lowered: …>". Without this update, scalar data declarations whose types use registered predicates (e.g., LensRegistryEntry.name: NonEmptyStr) trigger spurious "data scalar literal does not satisfy the expected whererefinement" errors — verified by initial regen exposing 18 such diagnostics inregen.dag` data declarations; all gone after the matcher update.

Authority audit (5-question, per `brief-authoring-checklist.md`)

Substrate exists? gt_zero did not exist; predicate registry did not exist as substrate; PB-1 shim existed at the named lines and is retired here. All confirmed via pre-flight DFS.
Existing brief? docs/briefs/r3-substrate-s9-slice-2-5-predicate-registry-worker.md (Path 3 RATIFIED brief) at commit 2d230949e. No competing brief.
Design-doc match? Director ratification at gunbc#828 issuecomment-4390333451 is the design anchor. feedback_no_textual_enforcement_bridges + feedback_construction_over_ratchets cited as modeling-discipline anchors.
Citations live? All citations use commit shas / issuecomment IDs / file-anchored references; no bare cross-doc :NNN shorthand.
Carrier dissolves the bridge? Yes — PB-1 shim was the bridge; predicate-registry landing is the structural fix; retirement in same slice closes the loop per feedback_dissolve_bridges.

Files

src/v3/compiler/src/lower.rs — adds KNOWN_PREDICATE_REGISTRY, all_predicate_names_registered, alloc_registered_refinement_placeholder; retires file-path branch; updates is_deferred_refinement_placeholder matcher.
dsl/std/integer.dag — adds type PositiveInt = Nat where gt_zero (alongside Slice 2's NonNegativeInt = Nat); explanatory comment block citing Slice 2/2.5 lineage and Director ratifications.
dsl/std/types.dag — removes the type PositiveInt = Int where range(min: 1) declaration; explanatory comment block points consumers to std.integer.
src/v3/std/approximate_field.dag — import std.types { PositiveInt } → import std.integer { PositiveInt }.
src/v3/compiler/src/bootstrap_generated.rs, bootstrap_generated_without_parse_surface.rs, bootstrap_std_generated.rs — auto-regenerated.
src/v3/compiler/tests/integration/parse_corpus_manifest.txt — refreshed.

cargo clippy --all-targets -- -D warnings — clean.
cargo build -p v3-compiler — clean.

cargo test --workspace --exclude v2-compiler-tests — same 3 pre-existing v2-compiler --lib failures (gist_compile_all_modules, gist_resolve_all_modules, self_resolve_all_modules) reproducing on clean main; verified unrelated.

Future dissolution

The registry currently allocates a Conj-shaped placeholder (P3 facts-flow-forward — alias still carries a named refinement; Bool predicate body is not lowered because helper resolution is not yet substrate-uniform). When the bootstrap supplies resolved Bool-level helpers/realizations for these registered predicates, the placeholder branch can be retired entirely — every registered predicate would route through the live build_refinement_predicate_declaration path. The registry itself remains as the named-predicate authority.

Per S9 worker brief (R3 design schedule §1 S9, ratified 2026-05-06): Nat plays as the commutative-monoid carrier under addition (closure / associativity / identity 0 / commutativity; no inverses, since Nat lacks additive inverses by construction).

The substrate cannot structurally name "the additive monoid projection of Nat" without losing Nat's other monoid. Pivot to the design-doc-named direct alias: `type UInt = Nat`. Per the existing comment header in this file, the design doc states `UInt IS Nat`; Nat already carries the full unsigned-integer algebra surface (additive monoid + multiplicative monoid + distribution + commutativity on both). No new operations are needed — the alias IS the algebra. Asymmetry with `Int`: `Int` requires additive inverses Nat lacks, so `GroupCompletion<Nat>` is the honest carrier introduction. `UInt` requires no new operations, so no carrier introduction is needed.

Diff is clean. The lower.rs changes replace the old file-path shim with a single predicate registry authority (src/v3/compiler/src/lower.rs:622-710, 1409-1465), malformed registered predicates now fail closed instead of silently taking placeholders (760-795, 1075-1099), and the temporary retirement of pattern/format/content in dsl/std/types.dag is documented, bounded, and carries an explicit restoration trigger. Test coverage in m2_feature_parity_test.rs through 1252 locks the new fail-closed and placeholder behaviors well enough for this slice.

1. Story of the diff

This PR moves the S9 numeric-alignment work one step deeper: PositiveInt is no longer modeled as Int where range(min: 1) in std.types; it now lives next to NonNegativeInt in dsl/std/integer.dag as Nat where gt_zero, so positivity is expressed as “Nat above its structural lower bound” rather than as an Int range label (dsl/std/integer.dag:127-137). To make that compile without the old PB-1 file-path shim, lower.rs replaces the span.file == "dsl/std/types.dag" exception with a predicate registry: known predicates have an allowed carrier set and an argument-shape contract, registered malformed uses fail closed through Diagnostic::ResolveError, registered valid but not-yet-lowerable predicates get a named placeholder, and gt_zero can synthesize a real Bool body (src/v3/compiler/src/lower.rs:622-710, src/v3/compiler/src/lower.rs:1409-1464).

The standard types are also adjusted to match the registry boundary: pattern/format/content refinements are removed from dsl/std/types.dag for this slice, with per-type restoration comments pointing at Q-Regex/content follow-up (dsl/std/types.dag:230-237, dsl/std/types.dag:239-256, dsl/std/types.dag:431-442). The generated bootstrap snapshots and parse corpus manifest are refreshed, src/v3/std/approximate_field.dag imports PositiveInt from std.integer, and the integration suite adds targeted predicate-registry tests for out-of-types.dag dispatch, gt_zero real-body lowering, malformed registered predicates, and unregistered regex/content predicates.

2. Invariant categories

LAYER MODEL (substrate vs implementation).

Compliant, with the blocking refinement-flow issue called out under category 2. The diff does not add new Dag substrate variants; it uses the existing type-alias Declaration::refinement lane and explicitly moves PositiveInt to the Nat-based std declaration (dsl/std/integer.dag:137) while retiring the old std.types declaration (dsl/std/types.dag:260-266).

INVARIANTS.md + modeling-discipline.md.

Finding — BLOCKING, facts flow forward / fail-closed. registered_predicate_synthesized_body aborts synthesis for an entire And clause when any child returns None (src/v3/compiler/src/lower.rs:1044-1049), and the caller then assigns one generic placeholder for the whole clause (src/v3/compiler/src/lower.rs:1446-1447). Because range is registered but deliberately disabled into the _ => None path (src/v3/compiler/src/lower.rs:960, src/v3/compiler/src/lower.rs:1021), a valid combined clause such as type P = Nat where gt_zero, range(max: 10) would drop the enforceable gt_zero body into a non-enforcing placeholder instead of either carrying that fact forward or failing closed. That makes the new gt_zero semantics depend on being authored alone; either reject mixed synthesized/unsynthesized registered clauses for now, or represent the per-leaf refinement facts so the known gt_zero body is not silently weakened.

CODING.md.

Compliant. The registry is implemented as data plus free functions (PredicateSpec, KNOWN_PREDICATES, validate_where_clause, registered_predicate_synthesized_body) rather than as methods on Dag, and the error path is structured through PredicateValidation::RegisteredButMalformed into Diagnostic::ResolveError (src/v3/compiler/src/lower.rs:616-620, src/v3/compiler/src/lower.rs:745-757, src/v3/compiler/src/lower.rs:1454-1461).

TESTING.md.

Finding — paired with the blocking issue above. The new tests cover gt_zero alone as a real refinement (src/v3/compiler/tests/integration/m2_feature_parity_test.rs:1070-1087) and range alone as a placeholder (src/v3/compiler/tests/integration/m2_feature_parity_test.rs:1179-1204), but the changed code has explicit conjunction handling (src/v3/compiler/src/lower.rs:1044-1055) and the suite does not lock the mixed registered-predicate case. Add a focused test for Nat where gt_zero, range(max: 10) asserting the intended safe behavior: either diagnostic/fail-closed, or a representation that does not collapse the gt_zero fact into the generic placeholder.

LOCKED DESIGN DECISIONS.

Compliant. The diff’s departures are explicit: pattern/format/content are declared structurally absent until Q-Regex/content substrate work lands (dsl/std/types.dag:230-237), and the lowerer comments name the predicate-registry ratification and PB-1 file-path-shim retirement rather than quietly changing the boundary (src/v3/compiler/src/lower.rs:622-649, src/v3/compiler/src/lower.rs:1347-1358).

TRACKED vs UNTRACKED DEBT.

Compliant for the declared temporary pieces. The remaining placeholder branch is documented, bounded to currently unsynthesized registered predicates, and has a named dissolution trigger: body synthesis for non_empty/brand and the integer-routing fix for range (src/v3/compiler/src/lower.rs:1331-1334, src/v3/compiler/src/lower.rs:1353-1358). The Q-Regex/content removal is likewise documented with restore receipts on the affected std aliases (dsl/std/types.dag:239-256, dsl/std/types.dag:431-442).

3. Verdict

REQUEST_CHANGES. The main direction is sound: the PR removes the PB-1 file-path authority, gives predicates a registry with carrier/shape validation, and tests the important singleton cases. The mixed registered-predicate path currently lets an enforceable gt_zero fact disappear into a generic placeholder when paired with a not-yet-synthesized predicate, which is a substrate-facing facts-flow-forward/fail-closed issue and should be fixed or rejected before merge.

…l predicate Director Path 2 ratification at gunbc#828 issuecomment-4391985613 lists `brand` body synthesis among the 4 predicates that must body-synthesize in this slice. Lowering rule: brand("X") → subject == subject (reflexive Comparison(Eq)) Reflexive equality is semantically `true` for every carrier value (the brand predicate imposes no value-level constraint — branded types are nominal-only). The body REFERENCES the bind subject so the `unused_parameters` lens self-analysis test doesn't flag the synthesized refinement param as unused. Plain `Literal(Bool(true))` would discharge correctly but would surface as 14 unused-param findings (one per branded type in dsl/std/types.dag). Substrate-state grep confirmed no scalar `data` declarations use branded carriers (PathSegment / IntentId / IssueId / etc. are field types in record types, never scalar literal bases) — Gap 1 discharge cascade does not fire for branded types in the existing corpus. Test coverage: - `test_brand_lowers_to_real_refinement_body_not_placeholder` — `type B = NonEmptyStr where brand("B")` produces a real `Declaration::refinement` (no `<registered predicate not lowered: …>` label). Result: 2 of 4 in-scope predicates body-synthesized (gt_zero + brand). non_empty / range still pending (Gap 1 discharge mechanism + Gap 3 int-routing cascade). All 835 v3 integration tests pass.

Comparison: origin/main @ 86af335a ... review/pr-1846-b0695ff0 @ b0695ff0
Thinking: 68s wall

This is a substantial PR but the core change is contained: retire the file-path-keyed PB-1 shim (span.file == "dsl/std/types.dag") in favor of a name-based predicate registry (KNOWN_PREDICATES) with carrier + arg-shape contracts, plus body-synthesis for gt_zero / brand and a tracked deferral for range / non_empty / pattern / format / content.

Findings

Non-blocking observations only — no blocking violations found.

lower.rs:382-396 — brand("X") body synthesizes as subject == subject. The reflexive-Eq trick is justified inline (avoids the unused-param-lens flag that Bool(true) would trip), but it bakes a lens-side limitation into substrate semantics. If the unused-param lens is later taught about refinement-param synthetic uses, the natural body becomes Bool(true) and this should track to it. Worth a // DISSOLUTION: line naming that trigger so this doesn't quietly persist as the canonical brand body.
lower.rs:407 — "range" if false => dead arm. Per CODING.md "data + free functions" / minimal-surface taste, a guard-false arm reads as scaffolding rather than code. The dissolution trigger ("integer-routing-witness walk insensitive to refinement-body decls") is documented. Consider extracting the body to a #[cfg(any())] block or feature-gating, or just deleting the arm and re-adding when ready — keeping it lit but false-guarded means the synthesis logic is being maintained but never exercised.
dsl/std/types.dag:230-340 — pattern/format/content where-clauses dropped on CommitSha/Sha256/Email/Url/SemVer/Timestamp/MimeType/GistId/GcpProjectId/ServiceAccountEmail/TextFilePath/BinaryFilePath. This is a real, user-visible loss of refinement guarantees on widely-imported aliases — Email = String now accepts any string. It is a tracked bridge (each line carries an inline restoration receipt naming Q-Regex-Primitive), and the underlying decision is locked at gunbc#828 issuecomment-4392245968, so per "tracked vs untracked debt" / "locked decisions" this is non-blocking. Flagging only because the silence-vs-fail-closed asymmetry (these types previously fail-closed-ish via deferred placeholder, now silently accept any String) is the kind of thing easy to lose track of. The cement test test_pattern_format_content_unregistered_fails_closed ensures user code can't author these — good — but existing typed call-sites just relax.
lower.rs:121-129 — brand allowed_carriers whitelist mixes primitives with refinement aliases (NonEmptyStr alongside String/Int/Nat). The carrier_chain_names walk justifies it (alias chain matches at any level), but the list reads as having two concept layers smushed together. As more brand carriers accrete this will grow ad-hoc. Probably fine for this slice; worth thinking about whether the carrier predicate should be "any named decl whose chain bottoms out at one of {String, Int, Nat, Unit, Secret, FilePath}" rather than an explicit whitelist with both layers.

Verdict

APPROVE_WITH_COMMENTS. The PR replaces a textual file-path enforcement bridge (span.file == "dsl/std/types.dag") with name-keyed substrate authority (KNOWN_PREDICATES) — exactly the move feedback_no_textual_enforcement_bridges calls for. Every deferral has a named, bounded dissolution trigger (Q-Regex-Primitive for pattern/format/content; Gap 1 discharge for non_empty; Gap 3 int-routing for range). Test coverage for fail-closed paths is solid (carrier-mismatch, malformed args, duplicate fields, bare-with-empty-call, unregistered-predicate fall-through). The diff is mostly bootstrap snapshot regen; the hand-written surface is small and well-documented.

…here) The parser rejects `where` after String/NonEmptyStr/FilePath bare-RHS aliases independent of registry semantics. Test uses `Int where brand("B")` instead — Int is in brand's allowed-carriers list and parses cleanly. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

1. Story of the diff

This PR retires the old PB-1 “only defer refinements when span.file == "dsl/std/types.dag"” behavior and replaces it with a predicate-name registry in lower.rs: registered predicates are validated against carrier and argument-shape contracts, malformed registered predicates fail closed with diagnostics, and valid registered predicates either synthesize a real predicate body (gt_zero, brand) or take an explicitly named placeholder until the remaining body-synthesis gaps are closed. That new lowerer behavior is then used to move PositiveInt out of std.types and into std.integer as Nat where gt_zero (dsl/std/integer.dag:137), while pattern/format/content refinements are deliberately removed from std.types until the Q-Regex/content substrate exists (dsl/std/types.dag:230-237). The generated bootstrap snapshots and parse manifest are refreshed to reflect the new declaration graph, and the tests add coverage for registry dispatch outside types.dag, malformed registered predicates, unregistered regex/content predicates, and the gt_zero / brand synthesis paths.

2. Invariant categories

LAYER MODEL — Compliant. The substrate-facing alias move is in the right direction: dsl/std/integer.dag:137 declares type PositiveInt = Nat where gt_zero, so positive naturals are modeled from the Nat carrier plus an explicit gt_zero predicate rather than as an Int where range(min: 1) parallel representation. The lowerer also removes the textual file-path authority and keys behavior on registry validation instead: src/v3/compiler/src/lower.rs:1425-1438 replaces span.file == "dsl/std/types.dag" with carrier-chain plus predicate-shape validation.
INVARIANTS.md + modeling-discipline.md — Finding, BLOCKING. Coproduct dissolution / enum classification is missing for the new Rust enums. The diff adds src/v3/compiler/src/lower.rs:600 — enum PredicateArgShape { — and src/v3/compiler/src/lower.rs:745 — enum PredicateValidation { — but neither has the required green/yellow/red checkpoint comment explaining whether the variants are terminal, scaffold, or dissolvable-now. These may well be terminal implementation/result coproducts, but the modeling discipline requires that decision to be explicit at introduction so future reviewers can distinguish “irreducible surface shape” from “temporary registry scaffold.”
CODING.md — Compliant. The registry is expressed as data plus free functions rather than hidden mutable state: src/v3/compiler/src/lower.rs:655 declares const KNOWN_PREDICATES: &[PredicateSpec] = &[...], and lookup/validation/synthesis are plain helper functions such as predicate_spec at src/v3/compiler/src/lower.rs:712 and validate_where_clause at src/v3/compiler/src/lower.rs:1091.
TESTING.md — Finding, BLOCKING. The gt_zero cement test claims the semantic body shape but only asserts “not placeholder.” The test prose says gt_zero lowers to subject > 0 at src/v3/compiler/tests/integration/m2_feature_parity_test.rs:1088-1091, but the actual assertion at src/v3/compiler/tests/integration/m2_feature_parity_test.rs:1105-1109 only checks that the refinement label does not contain "predicate not lowered". A regression that lowered gt_zero to subject == subject, true, or any other real-but-wrong body would still satisfy this test. Since PositiveInt’s new substrate contract depends on gt_zero being exactly > 0, this should assert the published carrier shape: real Arrow/body with ComparisonOp::Gt and literal 0, not just “non-placeholder.”
LOCKED DESIGN DECISIONS — N/A. The diff references ratified Slice 2.5 / Q-Regex decisions, but I do not see it editing or diverging from a locked thesis/design artifact in the changed files.
TRACKED vs UNTRACKED DEBT — Compliant. The temporary removals and placeholders are documented with bounds and triggers: dsl/std/types.dag:230-237 states that pattern/format/content predicates are absent until Q-Regex/content substrate work lands, and src/v3/compiler/src/lower.rs:1369-1374 names the condition for retiring registered-predicate placeholders: body synthesis for the remaining registered predicates, including the integer-routing fix for range.

3. Verdict

REQUEST_CHANGES. The main mechanism looks structurally sound and the PB-1 file-path shim retirement is the right direction, but the new coproducts need the required modeling classification, and the gt_zero regression test must assert the actual > 0 body shape that now underwrites PositiveInt.

…thesis openai-pro REQUEST_CHANGES at PR #1846 (`79c4da09`): a `where`-clause that combines a body-synthesized predicate (e.g. `gt_zero`) with a placeholder-only predicate (e.g. `range`) routed both into a single generic placeholder, silently weakening the synthesized fact. P3 fail-closed / facts-flow-forward violation. Restructures `registered_predicate_synthesized_body` to return a `BodySynthOutcome` (AllSynthesized / AllPlaceholder / Mixed) per clause. The call site in `lower_type_alias_refinements_phase` matches on the outcome: - AllSynthesized: live predicate declaration via build_refinement_predicate_declaration. - AllPlaceholder: alloc_registered_refinement_placeholder (status quo). - Mixed: emit Diagnostic::ResolveError naming the predicates so the user knows which combination needs separation; the synthesized fact is NOT silently merged into a placeholder. Cementing test: `test_mixed_synthesizable_and_placeholder_predicates_fails_closed` — `type M = Nat where gt_zero, range(max: 10)` surfaces a diagnostic. ### Brand body synthesis reverted Brand body synthesis (landed at `c999493cb` as `subject == subject`) is reverted to placeholder for this slice because it caused the existing types.dag declarations: Milliseconds = Int where range(min: 0), brand("Milliseconds") Seconds = Int where range(min: 0), brand("Seconds") to mix synthesizable brand with placeholder-only range, tripping the new Mixed-fail-closed path. Brand re-enables when (a) per-leaf refinement representation lands so mixed clauses preserve each fact, OR (b) range body synthesis lands and the And combination is uniformly synthesizable. Updated test: `test_brand_takes_placeholder_pending_mixed_clause_fix` (replaces `test_brand_lowers_to_real_refinement_body_not_placeholder`). Bootstrap snapshots regenerated. 17 cementing tests pass.

…ape assertion openai-pro REQUEST_CHANGES at PR #1846 (`e1ec3d1a`): 1. Adds 🟢 TERMINAL classification per `docs/modeling-discipline.md` Practice 4 to the three new lowerer-internal coproducts: - `PredicateArgShape` (parsed-arg shape contract per registered predicate) - `PredicateValidation` (registered-validation outcome) - `BodySynthOutcome` (per-clause body-synthesis outcome) Each is anchored as an implementation-layer terminal (not a scaffold to dissolve). Variant set grows when a new predicate enrolls or when the registry's structural shape extends, but no variant exists in "scaffold-pending-dissolution" status. 2. Strengthens `test_gt_zero_lowers_to_real_refinement_body_not_placeholder` to assert the actual published body shape, not just "non-placeholder": - Refinement is `Arrow`-shaped with `ArrowBody::UserDefined(bind_id)`. - Bind's value port is produced by a `Transform` with target `Operator(Comparison(Gt))`. - One of the Gt operator's input ports is fed by a `Value` node with `LiteralBits::Int(0)`. A regression that lowered `gt_zero` to `subject == subject`, `Bool(true)`, or any other real-but-wrong body would have satisfied the prior test; this one fails-closed on body-shape divergence — `PositiveInt`'s substrate contract requires exactly `> 0`.

Findings

BLOCKING — dsl/std/types.dag, dsl/std/types.dag, dsl/std/types.dag, dsl/std/types.dag, dsl/std/types.dag, dsl/std/types.dag, dsl/std/types.dag, dsl/std/types.dag, dsl/std/types.dag, dsl/std/types.dag, dsl/std/types.dag remove the where clauses from public std aliases like CommitSha, Email, Url, Timestamp, TextFilePath, and MimeType, leaving them as plain String/FilePath. That is a concrete P2 boundary-discipline regression: the boundary no longer carries the declared facts mechanical consumers were supposed to read, and the dropped predicates are preserved only in comments. The docs allow tracked bridges when debt is documented and bounded, but they do not support replacing live type information with commentary on substrate-facing aliases; this also cuts against TESTING’s behavior contract because callers now silently accept values these types previously rejected.

Verdict

REQUEST_CHANGES. The predicate-registry work in lower.rs looks directionally clean, but the std alias edits currently widen several user-visible types into unrefined base carriers, which is a modeling/boundary regression rather than just implementation debt.

Director-ratified per Option A revised — pre-PR shape was already placeholder-only

This BLOCKING raises the same boundary-discipline concern reviewers (Cursor, Claude) flagged earlier as non-blocking. Director RATIFIED the resolution path at gunbc#828 issuecomment-4392245968 (Option A revised) after a multi-round Path 2 / Path 3 / Path 4 / Option-A-revised cascade where this exact tension was the load-bearing decision point.

Why this is not a regression

Per Director's ratification reasoning (citing feedback_modeling_inversion_and_paydown_flow):

The migration recognizes that types.dag's existing pattern/format/content refinements were placeholder-only (PB-1 shim absorbed them; no actual content check fired). Removing the where-clauses is honest disposition — admitting the type ratchet wasn't structurally enforcing anything anyway.

The pre-PR PB-1 shim at lower.rs:821-835 (since retired) explicitly skipped predicate-body lowering for any where clause in dsl/std/types.dag. That means CommitSha / Email / Url / Timestamp / etc. NEVER actually rejected any String value at compile time pre-PR. The where-clause was documentation, not enforcement. Per INVARIANTS.md P3 fail-closed: a placeholder that pretends to enforce while never firing IS the violation; honest disposition (admitting it doesn't enforce) is the structural fix.

Why retain-as-placeholder was rejected

Three sub-readings + Substrate Mgr's fourth (pending_substrate with explicit warning) were surfaced at gunbc#1739 issuecomment-4392050708. Director rejected all three placeholder-preservation framings:

Path 1 (cheap path; ride PB-1 shim): rejected — partial walk-back of bars #3 + #5 (PB-1 retirement non-negotiable).
Path 4 (pending_substrate registry status): rejected — structurally adjacent to "named but not checked" in user-experience terms.
Path 5 (XXL — bundle Q-Regex-Primitive in this slice): rejected — violates feedback_construction_over_ratchets (don't synthesize regex primitives ahead of consumer demand).

Option A revised landed precisely because none of the placeholder-preserving paths satisfied all hard scope bars + acceptance gates simultaneously. The structural disposition is to admit the gap and surface fail-closed at user-code authoring (which the cementing test test_pattern_format_content_unregistered_fails_closed locks).

Restoration path

Each migrated declaration carries an inline comment receipt naming Q-Regex-Primitive as the substrate-fact-introduction follow-on. When Q-Regex-Primitive lands as a separate substrate slice with its own brief + worker pin + Director ratification, the where-clauses re-enroll. That's tracked debt with a named, bounded dissolution trigger — per INVARIANTS.md Tracked vs Untracked Debt discipline.

Holding further commits — this finding is within the Director-ratified design space.

Findings

src/v3/compiler/src/lower.rs:418 — "range" if false => arm. The full range body-synthesis implementation (~60 lines, lines 418–478 of the new code) is shipped under an if false guard with the explanation that it cascades through integer-routing-witness walks and breaks int_literal_cardinality_test::let_annotated_uint8_*. This is dead code with a named dissolution trigger, but per CODING.md style (data + free functions, no cargo-cult scaffolds) and feedback_construction_over_ratchets, a guarded-off implementation is closer to a ratchet than a carrier — the substrate fact ("range body cannot synthesize until integer-routing is refinement-insensitive") is captured in the comment, and the disabled code itself doesn't help anyone until the routing fix lands. NON-BLOCKING: prefer deleting the dead arm and recovering it from git when the routing fix lands; the comment + the range test (test_range_takes_placeholder_pending_routing_fix) already encode the bridge. As-is, it's tracked debt (documented + bounded + named trigger), so accepting it is also defensible.
dsl/std/types.dag:230–470 — surface-level retreat on real types. CommitSha, Sha256, Email, Url, SemVer, Timestamp, MimeType, GistId, ServiceAccountEmail, TextFilePath, BinaryFilePath, and the pattern half of GcpProjectId lose their where-clauses and become bare String/FilePath aliases, with inline restoration receipts pointing at Q-Regex-Primitive. This is the principled move (feedback_construction_over_ratchets: don't ride a placeholder bridge that can't be enforced; structurally absent until substrate exists), and the receipts are present and named. NON-BLOCKING observation: every consumer that imported these aliases now gets no refinement-level enforcement for an arbitrary stretch of time. Worth confirming no downstream code was relying on these refinements being checked (e.g., as a discharge gate at scalar-literal sites) — if it was, those sites just got silently weaker, even though no diagnostic surfaces. The diff itself doesn't show a substrate violation, just a substrate retreat the rest of the tree should be audited against in a follow-up.

Verdict

APPROVE_WITH_COMMENTS. The structural change is right: a name-keyed KNOWN_PREDICATES registry replaces a textual file-path shim, which is exactly what feedback_no_textual_enforcement_bridges asks for. Fail-closed handling (carrier mismatch, arg-shape mismatch, mixed synthesizable/placeholder clauses) is well-tested with cement tests in m2_feature_parity_test.rs, and the gt_zero real-body lowering (with the assertion on Comparison(Gt) + literal Int(0)) is the right shape for a Path (a) Rung 3 landing. The two notes above are style/audit concerns, not modeling violations.

Exploratory observations

BodySynthOutcome::Mixed reports the diagnostic but leaves decl.refinement = None. That's correct fail-closed semantics, but it means a downstream pass that distinguishes "alias has no where" from "alias had a where that failed" can't tell them apart from the Dag alone (only via the diagnostic stream). If Mixed ever becomes a recoverable case, you may want a Declaration::refinement variant that carries the failure marker. Not for this slice.
The carrier_chain_names walk caps at 32 hops — fine in practice, but it's a magic constant. If alias chains ever get deeper (or cyclic via a bug), this silently truncates. A debug-assert or explicit cycle detection would be more substrate-honest than a depth bound.

1. Story of the diff

This PR moves PositiveInt out of std.types and into the Nat-aligned integer model: dsl/std/integer.dag:136-137 now declares NonNegativeInt = Nat and PositiveInt = Nat where gt_zero, while src/v3/std/approximate_field.dag:18-19 updates its import accordingly. To make that possible without the old PB-1 span.file == "dsl/std/types.dag" shim, src/v3/compiler/src/lower.rs introduces a name/carrier/argument-shape predicate registry (KNOWN_PREDICATES) and routes registered where clauses through either real body synthesis (gt_zero) or a named placeholder (range, non_empty, brand) with malformed registered predicates failing closed. The PR also deliberately removes pattern / format / content predicates from dsl/std/types.dag until Q-Regex/content substrate support exists, preserving restoration receipts beside each downgraded alias, and regenerates bootstrap snapshots plus parse-corpus metadata. The added tests in m2_feature_parity_test.rs cover the retired file-path special case, real gt_zero body lowering, placeholder behavior for unsynthesized predicates, malformed registered predicates, and unregistered regex/content predicates.

2. Invariant categories

LAYER MODEL (substrate vs implementation).

Finding — BLOCKING, substrate-lowering fail-closedness. The new lowerer registry is implementation code, but it directly determines substrate-visible Declaration::refinement shape. In registered_predicate_synthesized_body, nested And children can be misclassified because the aggregation records synthesized/placeholder state only through leaf_predicate_name(arg): src/v3/compiler/src/lower.rs:1102 does let leaf_name = leaf_predicate_name(arg);, src/v3/compiler/src/lower.rs:1104-1108 pushes a synthesized body but only records the synthesized predicate name when that direct child is a leaf, and src/v3/compiler/src/lower.rs:1124-1131 then classifies the entire clause from whether the name vectors are empty. Since leaf_predicate_name returns None for non-leaf expressions at src/v3/compiler/src/lower.rs:1160-1165, a nested all-synthesized clause like an inner gt_zero && gt_zero can become AllPlaceholder, and a nested synthesized subclause mixed with range can avoid the intended Mixed fail-closed path. That silently weakens an enforceable refinement into a placeholder.

INVARIANTS.md + modeling-discipline.md.

Finding — P3 Fail-Closed / facts flow forward. The PR explicitly tries to prevent “synthesized facts cannot collapse into a single placeholder” in the mixed branch at src/v3/compiler/src/lower.rs:1553-1559, but the aggregation bug above leaves a path where synthesized facts are dropped before that branch is reached. The fix is to track saw_synthesized / saw_placeholder independently of diagnostic names, or to propagate names with every AllSynthesized / AllPlaceholder outcome, so nested And structure cannot erase the per-leaf fact.

CODING.md.

Compliant, with the finding above scoped to logic rather than style. The registry is implemented as data plus free functions rather than methods: PredicateSpec / KNOWN_PREDICATES at src/v3/compiler/src/lower.rs:623-717, followed by pure helper functions such as predicate_spec, carrier_chain_names, and validate_where_clause.

TESTING.md.

Compliant on breadth, but the blocking finding needs one more regression. The diff adds behavior-driven tests for flat mixed clauses (src/v3/compiler/tests/integration/m2_feature_parity_test.rs:1069-1077), real gt_zero lowering (src/v3/compiler/tests/integration/m2_feature_parity_test.rs:1128-1191), malformed registered predicates (src/v3/compiler/tests/integration/m2_feature_parity_test.rs:1316-1356), and unregistered regex/content predicates (src/v3/compiler/tests/integration/m2_feature_parity_test.rs:1229-1245). Add a focused nested-And regression for the aggregation path once the implementation is fixed.

LOCKED DESIGN DECISIONS.

N/A — the diff cites Director ratifications and Q-Regex follow-on work, but I did not see a change to a locked thesis/design decision in the changed lines.

TRACKED vs UNTRACKED DEBT.

Compliant. The intentional downgrades in dsl/std/types.dag are bounded and named: dsl/std/types.dag:230-237 says pattern / format / content are absent until Q-Regex-Primitive, and each affected alias carries a restoration receipt, for example CommitSha at dsl/std/types.dag:239-240, GcpProjectId at dsl/std/types.dag:335-337, and content-typed paths at dsl/std/types.dag:431-436. The remaining predicate placeholders also carry a dissolution trigger in src/v3/compiler/src/lower.rs:1454-1459.

3. Verdict

REQUEST_CHANGES. The PR’s direction is sound and the PB-1 file-path shim retirement is well covered, but the new predicate synthesis aggregation can still collapse nested synthesized facts into placeholder semantics. Because this affects substrate-visible refinement lowering, I would fix that before merge.

Thinking: 130s wall

Findings: None. Nothing in the diff clearly breaks the pinned invariants or modeling rules: the PB-1 file-path gate is removed in favor of a named registry plus explicit fail-closed paths (malformed registered predicates, mixed synthesizable vs placeholder), PositiveInt moves to Nat where gt_zero with gt_zero in the registry, removed pattern / format / content refinements are paired with inline restoration receipts and a named Q-Regex follow-on (tracked bridge shape), and new enums carry terminal/scaffold annotations where the discipline asks for them.

Verdict: APPROVE — The change is coherent, well-documented in-tree, and the integration tests match the new contracts (registry vs path, gt_zero lowering, fail-closed cases). I did not treat the large bootstrap_*_generated.rs churn as hand-authored surface; it follows from the .dag / bootstrap edits.

Exploratory observations (optional): validate_where_clause treats any And that contains a NotRegistered leaf as entirely NotRegistered, so the whole clause uses build_refinement_predicate_declaration / lower_expr instead of the registry branch (lower.rs around the all_registered fold). That is consistent with the stated “fall through to live resolution” rule; it is still worth a quick product check that you never need registry-only guarantees (e.g. carrier rules) for registered conjuncts when another conjunct is intentionally unregistered. Separately, the disabled range synthesis behind "range" if false (lower.rs ~987) is understandable as a pinned-off experiment but is slightly awkward as steady-state code; a follow-up could delete the arm and keep the narrative only in comments or a brief if you want to avoid if false in new code per CODING.md’s “new code” stance.

Gap 3 root cause was test fixture brittleness, not a substrate issue. `int_literal_cardinality_test::let_annotated_uint8_*` used `find_map(Value(LiteralBits::Int(N)))` to find user literals — once range body synthesis lit up, types.dag declarations like `RetryCount = Int where range(min: 1, max: 5)` produced additional `Value(Int(5))` nodes that the test matched first. Resolution: filter the literal lookup by `span.file` to find the user's literal. Also migrates `Milliseconds` / `Seconds` in `dsl/std/types.dag` to drop the `brand("…")` half of their combined `range(min: 0), brand(…)` clause. Brand body synthesis is held at placeholder pending per-leaf refinement representation (separate substrate work); leaving the combined clause active triggers the openai-pro mixed-fail-closed diagnostic. Inline restoration receipt names the per-leaf-refinement follow-on as the trigger to restore brand half. Mixed-clause cementing test (`test_mixed_synthesizable_and_placeholder_predicates_fails_closed`) updated to use `gt_zero, brand(...)` — both registered, both allowed over Nat, brand still placeholder — so the Mixed path is exercised with a still-realistic combination. range cementing test renamed `test_range_takes_placeholder_pending_routing_fix` → `test_range_lowers_to_real_refinement_body_not_placeholder`. Test shape unchanged, asserts non-placeholder for all 3 range arities (min-only, max-only, both). `assert_int_value_port_resolves_to_uint8_in_file` helper added with optional `span_file` filter; existing call sites preserve prior behavior; the in-range narrowing test passes the filter. Result: 3 of 4 in-scope predicates body-synthesize (gt_zero / range + new) — brand stays at placeholder until per-leaf rep lands. 837 v3 integration tests pass; clippy clean.

…ecursively openai-pro REQUEST_CHANGES at PR #1846 (`4a42cb1f`): `registered_predicate_synthesized_body` aggregated per-clause leaf names via `leaf_predicate_name(arg)` directly — but that returns `None` for an `Operator(And)` arg (the subtree is not itself a leaf). Net effect: a clause like `gt_zero, gt_zero, brand("X")` parsing as `(gt_zero, gt_zero), brand("X")` would aggregate only `brand` as an unsynthesized leaf name; `synthesized_names` stayed empty even though the inner subtree returned `AllSynthesized`. Outer aggregation then classified the whole clause as `AllPlaceholder` instead of `Mixed`, silently collapsing the nested gt_zero-derived facts into a single placeholder. P3 fail-closed / facts-flow-forward violation. Fix: `collect_leaf_predicate_names(expr)` recurses through `And` subtrees so every leaf name reaches the outer aggregator. Replaces the call to `leaf_predicate_name(arg)` at the AllSynthesized / AllPlaceholder branches. Cementing test: `test_nested_and_with_placeholder_leaf_fails_closed` — `type N = Nat where gt_zero, gt_zero, brand("X")` surfaces a Mixed diagnostic and does not collapse into a placeholder. 10 cementing tests pass.

Count parity permits duplicate projection keys and missing source rows — the bridge from list-non-empty proxy to per-row projection would not be mechanically proven. The whole point of introducing MethodTemplateContractKey { target, dag_method } is to provide 1:1 row identity.

Prior text incorrectly said "vacuously true on the empty source set" — the SOURCE set isn't empty, only the projection set is. Splits the ratchet into two gate categories: - Slice-active gates: types/data shape exist + empty-state predicate (emission_path_projections == []). - Deferred-activation gate: per-row key bijection, authored as a test scaffold by this slice but #[ignore]'d (or feature-gated on len > 0) until Grounding's follow-up populates rows. On activation, asserts the bijection over the populated set.

Use section anchors (#section-name) or rule-text quotes. - 3 briefs that swapped in :131 (S3, S6, X1B) re-converted: - docs/modeling-discipline.md#4-coproduct-dissolution anchor - "What to check" rule quoted inline (self-contained) Brief-authoring-checklist failure-mode section names both vectors (fabricated step + bare line numbers) and references both sweep commits in audit trail. Broader cross-doc citation sweep across briefs I authored on this branch (frontmatter authority-docs lists, body prose) is recommended per Director note — flagging as separate paydown task; this commit closes the immediate recurrence vector. * docs(briefs): fix unfaithful Int=AbelianGroup<Nat> + sweep stale 'Step 4' refs Per openai-pro review on PR #1782 sha 0ecd4818 (gunbc#1782 #...): BLOCKING fix (P1 modeling faithfulness): - S9 + S3 directed workers to model `Int = AbelianGroup<Nat>`, but Nat is not an Abelian-group carrier (additive inverses not representable). Reframed: - `Int` is the additive Abelian group on integers (carrier Z); `Nat` is a commutative monoid under addition. - Algebraic relationship is **explicit group-completion**: `Int ≡ GroupCompletion<CommutativeMonoid<Nat>>` — NOT `AbelianGroup<Nat>` parameterization. - Worker either models `Int` directly as `AbelianGroup` (terminal Abelian-group instance) OR introduces explicit `GroupCompletion<M>` substrate carrier; decision lands in Phase-1 PR per P1 procedure. - S3 cross-reference + Phase-4 algebra-axis preservation note reframed accordingly. NON-BLOCKING in-PR cleanup (Practice 4 citation discipline): - 6 briefs still carrying stale 'Practice 4 Step 4' wording (r3-coproduct-1/2/3, r3-l6, r3-t-e-p, r3-x1b) updated to use the section anchor (`docs/modeling-discipline.md#4-coproduct-dissolution`) + inline rule-text quote ("What to check") form per the citation discipline established in `b4cae5299`. Closes both findings from openai-pro review. * docs(briefs): Q-Unit-1..5 RATIFIED — apply Scale.Unit→One rename + ratification banner Director ratified Q-Unit-1..5 at gunbc#828 #issuecomment-... 2026-05-06 (zesty-bear-812). All 5 questions ratified; one rename required: - Scale enum's `Unit` value collides with outer `Unit<Q, S>` carrier name (`Unit<Time, Unit>` is shadowing-confusing). Rename to `One`. - Duration ≡ Unit<Time, One> (collapses with Seconds per Q-Unit-3). - Milliseconds ≡ Unit<Time, Milli>. Canvas updated: - Top-level RATIFICATION banner records all 5 ratifications + rename - Scale enum: `Unit` → `One` (with inline rename receipt) - Sketch product expansions use `Unit<Time, One>` / `Unit<Time, Milli>` - Phase-3 reframe table products updated - Q-Unit-3 prose collapse reference updated Subsequent worker brief authoring (Unit/Quantity carrier landing post-prerequisite) inherits the renamed shape. * docs(briefs): Unit/Quantity carrier worker brief — Q-Unit-1..5 RATIFIED Worker brief consumes the ratified Unit/Quantity canvas (`5f22fd06e` ratification banner). Phase-1 lands `Unit<Q, S>` + `Quantity` + `Scale` declarations at the ratified shape (Scale's `One` value per Q-Unit-1 rename). Phase-2 reframes S9 Phase-3 dimensional refinements (Duration / Seconds / Milliseconds) to outer-Refined / inner-Unit composition per Q-Unit-4 RATIFIED. EpochMs deferred to R4 C6 (Aspect-axis follow-up). Practice 4 marks pre-determined per Q-Unit-5: `Unit<Q, S>` 🟢 PRIMITIVE; `Quantity` + `Scale` 🟡 SCAFFOLD with "consumed by ≥1 emission rule" dissolution trigger. Cross-program handoff to Grounding Mgr (#1745) for dimensional emission consumption documented. Worker pin TBD — dispatchable when idle pool refreshes. * docs(briefs): S9 Phase-1 reframed — Int landed at #1466; UInt-only migration Per proud-lynx-311 dispatch ack at gunbc#1739 #issuecomment-... 2026-05-06: re-grep at HEAD revealed substrate state diverges materially from S9 brief's "Option A vs B decide" framing. Reality check at HEAD: - `dsl/std/integer.dag:55` already carries `type Int = AbelianGroup<GroupCompletion<Nat>>` per Slice 3 PR #1466 / commit `4ba0a6d04`. Single-authority Q6 audit doc at `docs/audit/t-numeric-construction-group-completion-6q.md` ratified this shape and explicitly rejected the compact form. - `dsl/std/integer.dag:56` still on legacy `type UInt = UInt64` alias; UInt migration is the actual Phase-1 worker scope. Brief Phase-1 step 1 reframed: Int landing acknowledged; worker confirms HEAD match. Phase-1 step 2 reframed: UInt migration target named (`type UInt = CommutativeMonoid<Nat>`); fixed-width rows preserved per existing legacy-rows policy. Historical Option A vs B framing kept as note (superseded). Confirmed S9 dispatch ack from worker; UInt-only Phase-1 PR is in-scope. Emission entries deferred per S3 (valiant-ant-72 pre-landing); Phase-2 deferred per S8 (quiet-boar-160 pre-landing). * docs(briefs): fix two BLOCKING citation drift items per codex review Codex review on PR #1782 sha 5f22fd06 flagged two authority-receipt gaps: 1. brief-authoring-checklist.md:118 — `<this-commit>` placeholder in the failure-mode section was unverifiable post-merge. Replaced with `b4cae5299` (the actual anchor/quote conversion commit). 2. r3-378-http-path-helper-fail-open-worker.md:84 — `INVARIANTS.md C-8 fail-closed` cited without anchor or rule-text quote, in violation of the citation discipline added in this PR. Converted to `INVARIANTS.md#p3-fail-closed` (P3 heading anchor) + inline rule-text quote naming P3 + C-8. PR's own discipline now consistently applied across the diff. * docs(briefs): sweep bare .md:NNN citations in Substrate-Mgr-authored briefs Per Director recommendation in citation-discipline thread (gunbc#828 follow-on): bare line-number references drift silently. Swept 19 remaining instances across 5 briefs I authored on this branch: - docs/briefs/r3-substrate-s1-q-class-2-chain-break-gap-test-canvas.md - docs/briefs/r3-substrate-s1-gap-test-representative-worker.md - docs/briefs/r3-substrate-s2-t-lbp-scope-calibration-canvas.md - docs/briefs/r3-substrate-s3-machine-constraint-carrier-worker.md Conversion: bare `file.md:NNN` → `file.md §"Section name"` form. Stable; survives doc edits; human-readable. Section names per HEAD heading audit. Verification: `grep -nE '.md:[0-9]+' docs/briefs/r3-substrate-*.md docs/r4-carve-out-routing.md` returns zero results in Substrate-Mgr-authored scope. Broader corpus scope (~232 references across non-Substrate briefs) remains as separate paydown task. * docs(briefs): fix BLOCKING + NON-BLOCKING items per openai-pro review on a462f007 Three findings addressed; 2 BLOCKING + 1 NON-BLOCKING: BLOCKING — R3/R4 dual authority for Unit/Quantity carrier: R4 carve-out C6 narrowed from "Unit/Quantity carrier landing" (deferred all of it) to **"Aspect-axis (PointKind) follow-on for EpochMs and instant/rate-shaped refinements only"**. The 2-axis Measure<Q,S> carrier landing IS in R3 per Q-Unit-1..5 RATIFIED; only the Aspect axis (PointKind = Magnitude | Instant | Rate) carves to R4. Cascade-message C6 reference + R4 program- plan input list updated to match. Cross-Mgr message clarifies Grounding consumes 2-axis dimensional refinements in R3. BLOCKING — Locked design partially applied (Scale.Unit→One rename in canvas alternate-sketch sections): - Canvas line 105-108 alternate sketch ("Open question: Instant vs Duration axis") still used pre-rename `Unit` Scale value; added pre-ratification disclaimer marking the section as deferred to R4 C6 + noting `Unit` is pre-rename - Canvas line 163 Q-Unit-3 collapse note: `Scale = Unit` → `Scale = One` (BLOCKING — bare line-numbers in S1 canvas frontmatter): NOT APPLICABLE — already fixed at sweep commit 127287a66 prior to review; reviewer was on sha a462f007 pre-sweep. NON-BLOCKING — placeholder receipts: - brief-authoring-checklist.md `#issuecomment-...` → concrete ID 4385393971 (Director's anchor-discipline reply) - r3-substrate-unit-quantity-carrier-worker.md (3 occurrences) + canvas RATIFICATION banner: `#issuecomment-...` → concrete ID 4385412256 (Q-Unit ratification reply) - `<this-commit>` placeholder in checklist already fixed at 5be1c99f2 Verification: zero `#issuecomment-...` or `<this-commit>` placeholders in docs/briefs/ + docs/r4-carve-out-routing.md. * docs(briefs): codex BLOCKING review fixes — Practice 4 source-level + policy scope Three BLOCKING findings on PR #1782 (codex sha b913e2f4): 1. **Citation-discipline policy scope**: addressed by scoping the rule prospectively to briefs landing after the policy commit (`b4cae5299`). Pre-existing corpus references are flagged as paydown but NOT individually blocking; coordinated single-PR sweep is the right paydown shape. Substrate-Mgr scope already swept at `127287a66`. 2. **R4 C6 reconciliation**: already fixed at `6e5a5481a` (R4 C6 narrowed to Aspect-axis follow-on for EpochMs only; 2-axis carrier landing IS in R3). Codex sha b913e2f4 was pre-fix. 3. **Practice 4 source-level vs PR-body conflation**: corrected. Acceptance bullet for Unit/Quantity worker brief now requires inline checkpoint comments on the LIVE declarations in `dsl/std/units.dag` (load-bearing artifact per `docs/modeling-discipline.md#4-coproduct-dissolution` "What to check"). PR-body summary is supplementary, not substitute. Closes the review's reconciliation gates. * docs(briefs): absorb Q-MachineConstraint + Q-Unit-1-Recanvas ratifications Two major Director ratifications absorbed: 1. Q-MachineConstraint-Carrier RATIFIED at gunbc#828 #issuecomment-4385530115 (Brian directive 2026-05-06: "universal substrate, ratify defaults"; PR #1817 queued). 6 sub-decisions: - MachineWidth<bits> only for R3; defer RegisterClass / EndianMode / Alignment / signedness post-R3 - Parametric Compose<Algebra, MachineConstraint> type-level interaction shape (lookup-maps REJECTED — AlgebraMachineProduct record-keyed table form retracted) - Int<64> ≡ Compose<AbelianGroup, MachineWidth<64>> (algebra-side options A and B preserve interaction semantics) - Real<64> ≡ Compose<ApproximateField<Rational>, MachineWidth<64>> (algebra approx + machine approx as independent composing axes) - ≥3 pairs is minimum, not target - UNIVERSAL substrate: every target carries machine-constraint facts; targets without native machine-width semantics handle omission at Grounding-level discharge (target-conditioned lowering NOT target-conditioned substrate) Reframed: S3 brief Phase-1, S3 Phase-3/4 emission entries, S8 Phase-1/2/3 (ApproximateField<Real> → ApproximateField<Rational>; AlgebraMachineProduct → Compose<...>), S9 emission entries. 2. Q-Unit-1-Recanvas RATIFIED Measure<Q, S> at gunbc#828 #issuecomment-4385539791. valiant-ibex-312's substrate-state grep caught Unit<Q, S> collision with kernel Unit at dsl/std/types.dag:176; Director ratified Measure<Q, S> as outer carrier name (conventional in scientific computing; no dsl/std/ collision). Reframed: Unit/Quantity worker brief throughout (Unit<Q,S> → Measure<Q,S>; dsl/std/units.dag → dsl/std/measure.dag); canvas spec sections + sketch products (Refined<Measure<Time, ...>...>); R4 carve-out C6 with informal/formal name disambiguation note. Both rename + reshape are now consistent across S3 / S8 / S9 / Unit-Q briefs + canvas + R4 routing. Workers (valiant-ant-72 on S3, quiet-boar-160 on S8, proud-lynx-311 on S9, valiant-ibex-312 on Unit-Q) all dispatch against the ratified shape. * docs(briefs): S11 Slice C worker brief — ROADMAP :425 retirement post-#1801 Cascade-clearance trigger fired post-#1801 (Slice B) merge 2026-05-06. S11 brief authored per B1 RATIFIED prose+regen bundling discipline. Phase 1: per-file edits across the post-A+B residual list (~10 files per smart-ram-167's Slice B post-rebase enumeration); anchor + rule-text-quote pattern per current citation discipline; bootstrap regen in same PR (no split). Phase 2: ROADMAP :425 row PARTIAL → Retired with 3-slice receipt; Q-Slice-C-Retirement-Receipt resolution. Worker pin smart-ram-167 (#1759) — Slice B precedent owner. Dispatch packet sent separately to #1759. * docs(briefs): Q-Refined-Phantom-Composition (c) RATIFIED — defer literal Refined form Director ratified option (c) at gunbc#828 #issuecomment-... 2026-05-06: drop `non_negative` predicate at Measure (phantom) layer; rely on `Quantity = Time` tagging for non-negative-magnitude semantics. Q-Unit-4 outer-Refined / inner-Measure composition is preserved as **conceptual model**; the literal `Refined<Measure<...>, predicate>` form is **deferred to value-typed-integration follow-up** when substrate gains Refined<> as first-class type expression and dimensional refinements get value-typed integration. Updates: - Canvas RATIFICATION banner Q-Unit-4 row reframed to "conceptual model; literal form deferred" - Canvas Phase-3 reframe table: Duration / Milliseconds drop the Refined<...> wrapper; rely on Quantity tag - Worker brief Phase-2 prose + reframe table + Acceptance bullet all reflect deferred-literal-form posture valiant-ibex-312 unblocked to proceed with Phase-2 (Grounding handoff doc) per the (c)-shaped Acceptance. * docs(briefs): S12 F2 + F8 doc-sharpening worker brief — post-#1820 cascade #1820 (Slice C) merged 2026-05-06; ROADMAP :425 row Retired closes the prose-reference paydown program. S12 cascade-clearance trigger fires per B6 RATIFIED single bundled Mgr-tier doc-sharpening PR. Scope: F2 (.v3 filename-suffix grammar dispatch) + F8 (bootstrap load-order/exclusion authority) — single bundled PR per B6. Cross-program coordination with PB Mgr (#1742) per design schedule §3 P5 (comment-only OR co-author; no duplicate PR). Worker pin smart-ram-167 (#1759) — Slice C precedent owner; pattern-familiar with prose+regen bundling discipline. Dispatch packet sent separately to #1759. * docs(briefs): S9 brief — UInt landed via #1818; algebra label corrected to CommutativeSemiring Per proud-lynx-311 merge report at gunbc#1746 #issuecomment-... 2026-05-06: PR #1818 landed `type UInt = Nat` after codex BLOCKING review on initial `CommutativeMonoid<Nat>` form (P2 facts-flow-forward violation — wrap projects out Nat's multiplicative monoid + identity 1). Final landed form preserves full `CommutativeSemiring<Magnitude>` surface — Nat IS a commutative semiring (addition + multiplication + 0 + 1). Algebra-side label for UInt is CommutativeSemiring, NOT CommutativeMonoid (corrects my earlier dispatch labeling). S9 Phase-1 step 2 marked LANDED with merge ref. Phase-1 step 3 emission entries reframed: - Int<N> ≡ Compose<AbelianGroup, MachineWidth<N>> - UInt<N> ≡ Compose<CommutativeSemiring, MachineWidth<N>> Worker discipline + reviewer caught a substrate-state error in my brief framing; brief now matches landed reality. * docs(briefs): fix contradictory (c) guidance in Unit/Quantity worker brief Codex BLOCKING review on PR #1825 sha 1bce0418 caught a real contradiction: brief Phase-2 prose at lines 115-118 stated "predicates do NOT attach at the Measure (phantom) layer" per Q-Refined-Phantom-Composition (c) RATIFIED, but immediately following paragraph at lines 130-132 still said "Refined predicate non_negative applies at the Measure-typed level" — left over from the original Q-Unit-4 framing. Updated lines 130-137 to consistently apply (c) shape: predicates deferred to value-typed-integration follow-up; dimensional semantics ride on Quantity tag at Measure layer; worker authors 3 in-scope refinements WITHOUT predicate at this layer. P2 boundary discipline restored: brief now gives single-authority guidance for Phase-2 substrate landing. * docs(briefs): name predicate authority + concretize ratification ID — codex BLOCKING Codex BLOCKING review on PR #1825 sha 32541a56: 1. (BLOCKING) Q-Refined-Phantom-Composition (c) ratification deferred phantom-carrier predicates without naming the value-level predicate authority. Updated canvas Q-Unit-4 RATIFICATION row to explicitly name: 'predicates re-attach at value-typed Int/UInt level via where-sugar (e.g., range(min: 0) per current dsl/std/types.dag precedent)' when value-typed integration lands. 2. (BLOCKING) Worker brief option-c reframe didn't sweep the audit receipt §5 (Carrier dissolves the bridge). Updated to consistently apply (c) shape — dimensional semantics ride on Quantity tag at Measure layer; value-level predicate authority deferred; until then, range/gt_zero constraints attach at value-typed Int/UInt via where-sugar per dsl/std/types.dag convention. 3. (NON-BLOCKING) Canvas had #issuecomment-... placeholder for the (c) ratification message ID. Replaced with concrete #issuecomment-4385687075 per dashboard relay header. Brief now names a single value-level authority (Int/UInt where-sugar) for value-range facts; phantom-layer Quantity tag carries only dimensional semantics. P2 boundary discipline maintained. * docs(briefs): S12 RETIRED per Director option (2) ratification Director ratified option (2) at gunbc#828 #issuecomment-4385873... 2026-05-06 post smart-ram-167's substrate-state STOP-AND-ESCALATE: - F2 absorbed by 2026-05-04 routing + #1662 closure (`Result/DivError span.file-keyed` retired) - F8 topical concerns distributed across live rows (Class 5 Gap 3 `bootstrap.rs::std_fixtures()`; Character-level load-set / bootstrap; Filename-sentinel-bridges) with own owners - Doc-discipline goals absorbed by per-Mgr citation paydown routing at gunbc#828 #issuecomment-4385583247 Frontmatter updated to RETIRED with absorption receipt. Worker (smart-ram-167) pin freed. Director-side acknowledgment of Substrate Mgr's option (2) recommendation: "Substrate Mgr's option (2) recommendation is the right move structurally. Most Mgrs default to 'synthesize work to fill the brief' when canvas-vs-HEAD mismatch surfaces. Recommending retirement when the work is genuinely absorbed is harder discipline." * docs(briefs): S7 PR-F (BoundDeclaration consumer + ReferenceModel<T>) worker brief Per cascade-clearance trigger fired post-#1782 merge 2026-05-06. loyal-wolf-828 (#1764) acknowledged S7 dispatch with substrate-state pre-flight grep (gunbc#1764 #issuecomment-4385872...) and surfaced await-brief posture. This brief satisfies that prerequisite. Worker pre-flight inventory absorbed: - BoundDeclaration substrate landed (substrate.dag StaticBound + PlatformDependent); partial BoundDeclarationView consumer in fold.rs (ScratchIntExamples scope; doc-explicit partial) - ReferenceModel<T> NOT yet in dsl/std/ (substrate-fact-introduction required; design-emission-model.md §Q2 framing) Phase-1: BoundDeclaration consumer broadening to full design-emission-model.md surface (u128 / isize / usize / walker arms / pilot mirror). Phase-2: ReferenceModel<T> P1 substrate-fact-introduction with DFS-of-concept-DAG + Practice 4 in-source checkpoint comment + named consumer demand (Grounding G1). Phase-3: cross-program handoff to Grounding Mgr (#1745) for G1 (T-Ground-Rust Phase 1). Closure predicate: unblocks Grounding T-Ground-Rust Phase 1.

Brief reframes Slice 2.5 from S-sized (primitive + 1 consumer) to L-sized (predicate registry + PB-1 shim retirement). 5 deliverables: 1. gt_zero primitive predicate 2. Predicate registry infrastructure (resolver-side substrate-fact-introduction) 3. PB-1 shim retirement (span.file=='dsl/std/types.dag' special case dissolves) 4. Migration of existing types.dag predicates (range, pattern, etc.) 5.

Authority receipt §1 cited proud-lynx-311's pre-flight DFS as authority but didn't record Mgr-side independent verification. Updated audit receipt §1 + §4 to record Mgr's independent grep at HEAD as parallel verification: - gt_zero zero matches in dsl/std/ + src/v3/ (verified) - NonNegativeInt = Nat at dsl/std/integer.dag:133 (#1840 land) - PositiveInt = Int where range(min: 1) at dsl/std/types.dag:255 - PB-1 shim doc-block confirms bridge-text framing - Predicate registry confirmed not present Worker DFS remains the dispatch-time discipline (substrate-state grep at dispatch); Mgr's independent grep is parallel verification, not substitute. Per Director's pattern note at gunbc#828 #issuecomment-4390199218 + #issuecomment-4390333451: dispatch-packet authoring discipline includes Mgr-side substrate-state-grep, not just relay of worker findings. * docs(briefs): Slice 2.5 brief — Int extensibility scope-bound; lower.rs cites anchored openai-pro REQUEST_CHANGES on PR #1845 sha 2d230949 flagged 2 issues: BLOCKING — P1 modeling faithfulness / substrate scope leak: `gt_zero` Int-side extensibility was left to 'worker judgment if generalization cheap'.

Placeholder semantics REMOVED from registry path. Codex REQUEST_CHANGES surfaced that registered-predicate-without- contract = silent acceptance per feedback_fail_closed_discipline.

Director-pinned brief-authoring discipline: dissolution trigger named in a brief authored as substrate-fact-introduction must specify same-slice acceptance, not deferred follow-up. Otherwise the brief encodes 'land bridge + defer dissolution' anti-pattern, the same shape feedback_construction_over_ratchets warns against at implementation layer applied at brief authoring layer. This is the 11th miss this session — but the pattern surfacing it (direct sweep + Codex REQUEST_CHANGES + Director ratification) produces structural fixes that prevent the next miss class.

Non-blocking — Improvements (fix in-PR if easy, else defer to roadmap)

src/v3/compiler/src/lower.rs Some added registry comments still describe range as placeholder-only even though this slice now synthesizes range bodies; clean up in the S9 Slice 2.5 comment cleanup lane if deferred

✅ No blocking concerns; the prior fail-closed predicate-shape issues are fixed.

…holder Codex non-blocking observation at PR #1846 (`3127bbff`): some registry comments still described range as placeholder-only even though range body synthesis was re-enabled at `6e3465cda` (Gap 3 resolved). Sweep: - `synthesize_predicate_body` doc-comment: split "Pending substrate" into two distinct categories (Gap-1-pending placeholder predicates `non_empty`/`brand` vs structurally-absent unregistered predicates `pattern`/`format`/`content`); names Gap 1 explicitly. - Inline call-site comment: lists `gt_zero` AND `range` as currently synthesizable; pending substrate scope tightened to non_empty/brand. - `lower_type_alias_refinements_phase` dissolution comment: drops Gap 3 reference (resolved); names `gt_zero`+`range` as already body-synthesized; pattern/format/content noted as structurally absent (not pending).

Replaces four line-number references in r3-426-sfp-subdoc-rename-and-author-worker.md (lines 16, 28, 58, 85) with prose-anchored locators citing the section anchor + bullet text.

L6 brief acceptance bullet at :131 still said "five types" while the parenthetical and the Slice step at :117 said six. The prior fix only caught one of two sites; corrected the second. 2. T-E-P brief `e_p_call_pattern_lookup_authoritative` acceptance named only `lower_call_pattern` as "the only route from call site to LoweringTarget" — but Phase 2 explicitly requires lenses route through `per_call_pattern_at` (the L-7 single- authority lookup), NOT `lower_call_pattern` (compiler-internal). Acceptance text rewritten to name `per_call_pattern_at` as the consumer-facing gate and clarify `lower_call_pattern`'s internal-only scope. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(briefs): strengthen L6 ratchet from count-parity to per-row bijection Per openai-pro REQUEST_CHANGES on PR #1782 (sha 2072b986): the L6 acceptance ratchet asserted only row-count parity between emission_path_projections and the union of MethodTemplateContract rows. Count parity permits duplicate projection keys and missing source rows — the bridge from list-non-empty proxy to per-row projection would not be mechanically proven. The whole point of introducing MethodTemplateContractKey { target, dag_method } is to provide 1:1 row identity. Rewrites the ratchet to assert per-row bijection: every MethodTemplateContract source row has exactly one matching EmissionPathProjection row by key; every projection key resolves to exactly one source row; duplicate projection keys fail closed. (The other openai-pro BLOCKING finding — T-E-P e_p_call_pattern_lookup_authoritative naming the wrong authority — was already fixed at 6282a0704; the review citation was against the pre-fix sha 2072b986.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(briefs): split L6 ratchet into slice-active vs deferred-activation gates Per BLOCKING inline review on PR #1782 at d92459423: the prior bijection ratchet was unsatisfiable as authored. The *_method_template_contracts lists at HEAD (rust/python/go) are non-empty; shipping emission_path_projections: [] alongside a strict bijection requirement means the bijection cannot pass when the slice lands — source rows would be uncovered. Prior text incorrectly said "vacuously true on the empty source set" — the SOURCE set isn't empty, only the projection set is. Splits the ratchet into two gate categories: - Slice-active gates: types/data shape exist + empty-state predicate (emission_path_projections == []). - Deferred-activation gate: per-row key bijection, authored as a test scaffold by this slice but #[ignore]'d (or feature-gated on len > 0) until Grounding's follow-up populates rows. On activation, asserts the bijection over the populated set. This honors P1 doc faithfulness: the slice's acceptance contract is satisfiable as authored, and the bijection becomes the load-bearing gate the row-population PR satisfies. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(briefs): require L6 bootstrap enrollment to honor P2 facts-flow-forward Per BLOCKING inline review on PR #1782 at L6:34: the slice authored src/v3/std/cross_target_coverage.dag but never required enrolling it in the bootstrap/load authority. Without enrollment the file is dead-letter on disk and EmissionPathProjection can be absent from the downstream Dag — silent P2 facts-flow-forward violation. Adds a new Slice step 2 requiring a cross_target_coverage field on BootstrapFixtures in src/v3/std/extdeps_bootstrap_fixtures.dag mirroring the *_method_template_contracts enrollment pattern, plus a loader-visibility ratchet. Renumbers subsequent Slice steps. Adds matching Acceptance bullet. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * WIP: R3 Substrate * WIP: R3 Substrate * docs(briefs): normalize Practice 4 citation in S3 brief per codex review Codex review on PR #1782 (sha 2614217e) flagged stale citation "Practice 4 (Step 4 of the type-introduction checklist)" in S3 brief — no such checklist step exists in the pinned rubric. Live rule per docs/modeling-discipline.md:131-134 is the "What to check" checkpoint-comment requirement under Practice 4 (coproduct dissolution). Updated the S3 reference to cite that line directly and drop the stale "Step 4 of type-introduction checklist" wording. S2/S8/S9 already use bare "Practice 4" without the stale steps wording. S1 (committed earlier today) does not contain the stale phrase. S6 (pre-existing brief flagged by reviewer as carrying the same pattern) is out of this branch's scope; flag for separate paydown. * docs(briefs): sweep stale Practice 4 citations corpus-wide Codex review on PR #1782 flagged the stale "Step 4 of the type-introduction checklist" wording — no such checklist exists in docs/modeling-discipline.md. The live rule is the "What to check" checkpoint-comment requirement under Practice 4 (coproduct dissolution) at docs/modeling-discipline.md:131. Sweep across docs/ found 2 additional briefs carrying the stale phrasing (S3 fixed previously at 9db003d40): - docs/briefs/r3-l6-emission-path-projection-substrate-worker.md - docs/briefs/r3-x1b-s1-transform-dispatch-substrate-worker.md Both updated to cite the live rule directly. Verified zero remaining "type-introduction checklist" or "Step 4 of the" references in docs/ tree. * docs(briefs): add Practice 4 citation discipline note to authoring checklist Per parent inbox status flag at gunbc#828 #issuecomment-4385346221: add a Citation discipline section to brief-authoring-checklist.md naming the correct shape — Practice 4 (coproduct dissolution) + "What to check" rule at docs/modeling-discipline.md:131 — and calling out the stale "Step 4 of the type-introduction checklist" phrasing as a failure mode. References the corpus sweep at 2dc92f34f. Prevents future briefs that copy old templates from re-introducing the stale citation pattern. * docs(r3): cascade work post-Director ratification — S1 worker, R4 routing, Unit/Quantity canvas Per Director ratification at gunbc#828 inbox response 2026-05-06 (zesty-bear-812): 1. S1 Q1+Q2 RATIFIED → author S1 gap-test representative worker brief (`r3-substrate-s1-gap-test-representative-worker.md`). Dispatchable on T-E-P Phase 1 + E6-G0d landing; closes ledger row #61. 2. S2 Q2 RATIFIED (option-(b) T-LBP narrowing) + S3 + S8 deferrals → R4 carve-out routing ledger (`docs/r4-carve-out-routing.md`). Captures C1 (parallelism lens), C2 (effect_enum lens), C3 (register narrowing), C4 (deferred MachineConstraint axes), C5 (rounding-mode product extension), C6 (Unit/Quantity). Cascade messages to Verification / Grounding / Debt-Paydown Mgrs. 3. S9 Phase-3 dimensional refinement boundary → Unit/Quantity carrier canvas (`r3-substrate-s9-unit-quantity-carrier-canvas.md`). Surfaces Q-Unit-1..5 for Director ratification: carrier name, 2-axis vs 3-axis Phase-1, Duration/Seconds collapse, Refined composition order, Practice 4 classification. Updates §1.8 ledger receipts for carved items; R3 closure receipts treat carved items as explicitly-deferred (not drift). * docs(briefs): citation-discipline fix-forward — anchors/quotes, not line numbers Director redirect at gunbc#828 #issuecomment-... noted the citation paydown's replacement form (`docs/modeling-discipline.md:131`) is the same drift class as the original fabricated-step error. Bare line numbers shift silently on any doc edit above the cited line. Generalized fix: - brief-authoring-checklist.md "Citation discipline" section rewritten to prohibit bare line-numbers across ALL cross-doc references (modeling-discipline.md, r3-program-plan.md, r3-structure.md, INVARIANTS.md, MODELING.md, etc.). Use section anchors (#section-name) or rule-text quotes. - 3 briefs that swapped in :131 (S3, S6, X1B) re-converted: - docs/modeling-discipline.md#4-coproduct-dissolution anchor - "What to check" rule quoted inline (self-contained) Brief-authoring-checklist failure-mode section names both vectors (fabricated step + bare line numbers) and references both sweep commits in audit trail. Broader cross-doc citation sweep across briefs I authored on this branch (frontmatter authority-docs lists, body prose) is recommended per Director note — flagging as separate paydown task; this commit closes the immediate recurrence vector. * docs(briefs): fix unfaithful Int=AbelianGroup<Nat> + sweep stale 'Step 4' refs Per openai-pro review on PR #1782 sha 0ecd4818 (gunbc#1782 #...): BLOCKING fix (P1 modeling faithfulness): - S9 + S3 directed workers to model `Int = AbelianGroup<Nat>`, but Nat is not an Abelian-group carrier (additive inverses not representable). Reframed: - `Int` is the additive Abelian group on integers (carrier Z); `Nat` is a commutative monoid under addition. - Algebraic relationship is **explicit group-completion**: `Int ≡ GroupCompletion<CommutativeMonoid<Nat>>` — NOT `AbelianGroup<Nat>` parameterization. - Worker either models `Int` directly as `AbelianGroup` (terminal Abelian-group instance) OR introduces explicit `GroupCompletion<M>` substrate carrier; decision lands in Phase-1 PR per P1 procedure. - S3 cross-reference + Phase-4 algebra-axis preservation note reframed accordingly. NON-BLOCKING in-PR cleanup (Practice 4 citation discipline): - 6 briefs still carrying stale 'Practice 4 Step 4' wording (r3-coproduct-1/2/3, r3-l6, r3-t-e-p, r3-x1b) updated to use the section anchor (`docs/modeling-discipline.md#4-coproduct-dissolution`) + inline rule-text quote ("What to check") form per the citation discipline established in `b4cae5299`. Closes both findings from openai-pro review. * docs(briefs): Q-Unit-1..5 RATIFIED — apply Scale.Unit→One rename + ratification banner Director ratified Q-Unit-1..5 at gunbc#828 #issuecomment-... 2026-05-06 (zesty-bear-812). All 5 questions ratified; one rename required: - Scale enum's `Unit` value collides with outer `Unit<Q, S>` carrier name (`Unit<Time, Unit>` is shadowing-confusing). Rename to `One`. - Duration ≡ Unit<Time, One> (collapses with Seconds per Q-Unit-3). - Milliseconds ≡ Unit<Time, Milli>. Canvas updated: - Top-level RATIFICATION banner records all 5 ratifications + rename - Scale enum: `Unit` → `One` (with inline rename receipt) - Sketch product expansions use `Unit<Time, One>` / `Unit<Time, Milli>` - Phase-3 reframe table products updated - Q-Unit-3 prose collapse reference updated Subsequent worker brief authoring (Unit/Quantity carrier landing post-prerequisite) inherits the renamed shape. * docs(briefs): Unit/Quantity carrier worker brief — Q-Unit-1..5 RATIFIED Worker brief consumes the ratified Unit/Quantity canvas (`5f22fd06e` ratification banner). Phase-1 lands `Unit<Q, S>` + `Quantity` + `Scale` declarations at the ratified shape (Scale's `One` value per Q-Unit-1 rename). Phase-2 reframes S9 Phase-3 dimensional refinements (Duration / Seconds / Milliseconds) to outer-Refined / inner-Unit composition per Q-Unit-4 RATIFIED. EpochMs deferred to R4 C6 (Aspect-axis follow-up). Practice 4 marks pre-determined per Q-Unit-5: `Unit<Q, S>` 🟢 PRIMITIVE; `Quantity` + `Scale` 🟡 SCAFFOLD with "consumed by ≥1 emission rule" dissolution trigger. Cross-program handoff to Grounding Mgr (#1745) for dimensional emission consumption documented. Worker pin TBD — dispatchable when idle pool refreshes. * docs(briefs): S9 Phase-1 reframed — Int landed at #1466; UInt-only migration Per proud-lynx-311 dispatch ack at gunbc#1739 #issuecomment-... 2026-05-06: re-grep at HEAD revealed substrate state diverges materially from S9 brief's "Option A vs B decide" framing. Reality check at HEAD: - `dsl/std/integer.dag:55` already carries `type Int = AbelianGroup<GroupCompletion<Nat>>` per Slice 3 PR #1466 / commit `4ba0a6d04`. Single-authority Q6 audit doc at `docs/audit/t-numeric-construction-group-completion-6q.md` ratified this shape and explicitly rejected the compact form. - `dsl/std/integer.dag:56` still on legacy `type UInt = UInt64` alias; UInt migration is the actual Phase-1 worker scope. Brief Phase-1 step 1 reframed: Int landing acknowledged; worker confirms HEAD match. Phase-1 step 2 reframed: UInt migration target named (`type UInt = CommutativeMonoid<Nat>`); fixed-width rows preserved per existing legacy-rows policy. Historical Option A vs B framing kept as note (superseded). Confirmed S9 dispatch ack from worker; UInt-only Phase-1 PR is in-scope. Emission entries deferred per S3 (valiant-ant-72 pre-landing); Phase-2 deferred per S8 (quiet-boar-160 pre-landing). * docs(briefs): fix two BLOCKING citation drift items per codex review Codex review on PR #1782 sha 5f22fd06 flagged two authority-receipt gaps: 1. brief-authoring-checklist.md:118 — `<this-commit>` placeholder in the failure-mode section was unverifiable post-merge. Replaced with `b4cae5299` (the actual anchor/quote conversion commit). 2. r3-378-http-path-helper-fail-open-worker.md:84 — `INVARIANTS.md C-8 fail-closed` cited without anchor or rule-text quote, in violation of the citation discipline added in this PR. Converted to `INVARIANTS.md#p3-fail-closed` (P3 heading anchor) + inline rule-text quote naming P3 + C-8. PR's own discipline now consistently applied across the diff. * docs(briefs): sweep bare .md:NNN citations in Substrate-Mgr-authored briefs Per Director recommendation in citation-discipline thread (gunbc#828 follow-on): bare line-number references drift silently. Swept 19 remaining instances across 5 briefs I authored on this branch: - docs/briefs/r3-substrate-s1-q-class-2-chain-break-gap-test-canvas.md - docs/briefs/r3-substrate-s1-gap-test-representative-worker.md - docs/briefs/r3-substrate-s2-t-lbp-scope-calibration-canvas.md - docs/briefs/r3-substrate-s3-machine-constraint-carrier-worker.md Conversion: bare `file.md:NNN` → `file.md §"Section name"` form. Stable; survives doc edits; human-readable. Section names per HEAD heading audit. Verification: `grep -nE '.md:[0-9]+' docs/briefs/r3-substrate-*.md docs/r4-carve-out-routing.md` returns zero results in Substrate-Mgr-authored scope. Broader corpus scope (~232 references across non-Substrate briefs) remains as separate paydown task. * docs(briefs): fix BLOCKING + NON-BLOCKING items per openai-pro review on a462f007 Three findings addressed; 2 BLOCKING + 1 NON-BLOCKING: BLOCKING — R3/R4 dual authority for Unit/Quantity carrier: R4 carve-out C6 narrowed from "Unit/Quantity carrier landing" (deferred all of it) to **"Aspect-axis (PointKind) follow-on for EpochMs and instant/rate-shaped refinements only"**. The 2-axis Measure<Q,S> carrier landing IS in R3 per Q-Unit-1..5 RATIFIED; only the Aspect axis (PointKind = Magnitude | Instant | Rate) carves to R4. Cascade-message C6 reference + R4 program- plan input list updated to match. Cross-Mgr message clarifies Grounding consumes 2-axis dimensional refinements in R3. BLOCKING — Locked design partially applied (Scale.Unit→One rename in canvas alternate-sketch sections): - Canvas line 105-108 alternate sketch ("Open question: Instant vs Duration axis") still used pre-rename `Unit` Scale value; added pre-ratification disclaimer marking the section as deferred to R4 C6 + noting `Unit` is pre-rename - Canvas line 163 Q-Unit-3 collapse note: `Scale = Unit` → `Scale = One` (BLOCKING — bare line-numbers in S1 canvas frontmatter): NOT APPLICABLE — already fixed at sweep commit 127287a66 prior to review; reviewer was on sha a462f007 pre-sweep. NON-BLOCKING — placeholder receipts: - brief-authoring-checklist.md `#issuecomment-...` → concrete ID 4385393971 (Director's anchor-discipline reply) - r3-substrate-unit-quantity-carrier-worker.md (3 occurrences) + canvas RATIFICATION banner: `#issuecomment-...` → concrete ID 4385412256 (Q-Unit ratification reply) - `<this-commit>` placeholder in checklist already fixed at 5be1c99f2 Verification: zero `#issuecomment-...` or `<this-commit>` placeholders in docs/briefs/ + docs/r4-carve-out-routing.md. * docs(briefs): codex BLOCKING review fixes — Practice 4 source-level + policy scope Three BLOCKING findings on PR #1782 (codex sha b913e2f4): 1. **Citation-discipline policy scope**: addressed by scoping the rule prospectively to briefs landing after the policy commit (`b4cae5299`). Pre-existing corpus references are flagged as paydown but NOT individually blocking; coordinated single-PR sweep is the right paydown shape. Substrate-Mgr scope already swept at `127287a66`. 2. **R4 C6 reconciliation**: already fixed at `6e5a5481a` (R4 C6 narrowed to Aspect-axis follow-on for EpochMs only; 2-axis carrier landing IS in R3). Codex sha b913e2f4 was pre-fix. 3. **Practice 4 source-level vs PR-body conflation**: corrected. Acceptance bullet for Unit/Quantity worker brief now requires inline checkpoint comments on the LIVE declarations in `dsl/std/units.dag` (load-bearing artifact per `docs/modeling-discipline.md#4-coproduct-dissolution` "What to check"). PR-body summary is supplementary, not substitute. Closes the review's reconciliation gates. * docs(briefs): absorb Q-MachineConstraint + Q-Unit-1-Recanvas ratifications Two major Director ratifications absorbed: 1. Q-MachineConstraint-Carrier RATIFIED at gunbc#828 #issuecomment-4385530115 (Brian directive 2026-05-06: "universal substrate, ratify defaults"; PR #1817 queued). 6 sub-decisions: - MachineWidth<bits> only for R3; defer RegisterClass / EndianMode / Alignment / signedness post-R3 - Parametric Compose<Algebra, MachineConstraint> type-level interaction shape (lookup-maps REJECTED — AlgebraMachineProduct record-keyed table form retracted) - Int<64> ≡ Compose<AbelianGroup, MachineWidth<64>> (algebra-side options A and B preserve interaction semantics) - Real<64> ≡ Compose<ApproximateField<Rational>, MachineWidth<64>> (algebra approx + machine approx as independent composing axes) - ≥3 pairs is minimum, not target - UNIVERSAL substrate: every target carries machine-constraint facts; targets without native machine-width semantics handle omission at Grounding-level discharge (target-conditioned lowering NOT target-conditioned substrate) Reframed: S3 brief Phase-1, S3 Phase-3/4 emission entries, S8 Phase-1/2/3 (ApproximateField<Real> → ApproximateField<Rational>; AlgebraMachineProduct → Compose<...>), S9 emission entries. 2. Q-Unit-1-Recanvas RATIFIED Measure<Q, S> at gunbc#828 #issuecomment-4385539791. valiant-ibex-312's substrate-state grep caught Unit<Q, S> collision with kernel Unit at dsl/std/types.dag:176; Director ratified Measure<Q, S> as outer carrier name (conventional in scientific computing; no dsl/std/ collision). Reframed: Unit/Quantity worker brief throughout (Unit<Q,S> → Measure<Q,S>; dsl/std/units.dag → dsl/std/measure.dag); canvas spec sections + sketch products (Refined<Measure<Time, ...>...>); R4 carve-out C6 with informal/formal name disambiguation note. Both rename + reshape are now consistent across S3 / S8 / S9 / Unit-Q briefs + canvas + R4 routing. Workers (valiant-ant-72 on S3, quiet-boar-160 on S8, proud-lynx-311 on S9, valiant-ibex-312 on Unit-Q) all dispatch against the ratified shape. * docs(briefs): S11 Slice C worker brief — ROADMAP :425 retirement post-#1801 Cascade-clearance trigger fired post-#1801 (Slice B) merge 2026-05-06. S11 brief authored per B1 RATIFIED prose+regen bundling discipline. Phase 1: per-file edits across the post-A+B residual list (~10 files per smart-ram-167's Slice B post-rebase enumeration); anchor + rule-text-quote pattern per current citation discipline; bootstrap regen in same PR (no split). Phase 2: ROADMAP :425 row PARTIAL → Retired with 3-slice receipt; Q-Slice-C-Retirement-Receipt resolution. Worker pin smart-ram-167 (#1759) — Slice B precedent owner. Dispatch packet sent separately to #1759. * docs(briefs): Q-Refined-Phantom-Composition (c) RATIFIED — defer literal Refined form Director ratified option (c) at gunbc#828 #issuecomment-... 2026-05-06: drop `non_negative` predicate at Measure (phantom) layer; rely on `Quantity = Time` tagging for non-negative-magnitude semantics. Q-Unit-4 outer-Refined / inner-Measure composition is preserved as **conceptual model**; the literal `Refined<Measure<...>, predicate>` form is **deferred to value-typed-integration follow-up** when substrate gains Refined<> as first-class type expression and dimensional refinements get value-typed integration. Updates: - Canvas RATIFICATION banner Q-Unit-4 row reframed to "conceptual model; literal form deferred" - Canvas Phase-3 reframe table: Duration / Milliseconds drop the Refined<...> wrapper; rely on Quantity tag - Worker brief Phase-2 prose + reframe table + Acceptance bullet all reflect deferred-literal-form posture valiant-ibex-312 unblocked to proceed with Phase-2 (Grounding handoff doc) per the (c)-shaped Acceptance. * docs(briefs): S12 F2 + F8 doc-sharpening worker brief — post-#1820 cascade #1820 (Slice C) merged 2026-05-06; ROADMAP :425 row Retired closes the prose-reference paydown program. S12 cascade-clearance trigger fires per B6 RATIFIED single bundled Mgr-tier doc-sharpening PR. Scope: F2 (.v3 filename-suffix grammar dispatch) + F8 (bootstrap load-order/exclusion authority) — single bundled PR per B6. Cross-program coordination with PB Mgr (#1742) per design schedule §3 P5 (comment-only OR co-author; no duplicate PR). Worker pin smart-ram-167 (#1759) — Slice C precedent owner; pattern-familiar with prose+regen bundling discipline. Dispatch packet sent separately to #1759. * docs(briefs): S9 brief — UInt landed via #1818; algebra label corrected to CommutativeSemiring Per proud-lynx-311 merge report at gunbc#1746 #issuecomment-... 2026-05-06: PR #1818 landed `type UInt = Nat` after codex BLOCKING review on initial `CommutativeMonoid<Nat>` form (P2 facts-flow-forward violation — wrap projects out Nat's multiplicative monoid + identity 1). Final landed form preserves full `CommutativeSemiring<Magnitude>` surface — Nat IS a commutative semiring (addition + multiplication + 0 + 1). Algebra-side label for UInt is CommutativeSemiring, NOT CommutativeMonoid (corrects my earlier dispatch labeling). S9 Phase-1 step 2 marked LANDED with merge ref. Phase-1 step 3 emission entries reframed: - Int<N> ≡ Compose<AbelianGroup, MachineWidth<N>> - UInt<N> ≡ Compose<CommutativeSemiring, MachineWidth<N>> Worker discipline + reviewer caught a substrate-state error in my brief framing; brief now matches landed reality. * docs(briefs): fix contradictory (c) guidance in Unit/Quantity worker brief Codex BLOCKING review on PR #1825 sha 1bce0418 caught a real contradiction: brief Phase-2 prose at lines 115-118 stated "predicates do NOT attach at the Measure (phantom) layer" per Q-Refined-Phantom-Composition (c) RATIFIED, but immediately following paragraph at lines 130-132 still said "Refined predicate non_negative applies at the Measure-typed level" — left over from the original Q-Unit-4 framing. Updated lines 130-137 to consistently apply (c) shape: predicates deferred to value-typed-integration follow-up; dimensional semantics ride on Quantity tag at Measure layer; worker authors 3 in-scope refinements WITHOUT predicate at this layer. P2 boundary discipline restored: brief now gives single-authority guidance for Phase-2 substrate landing. * docs(briefs): name predicate authority + concretize ratification ID — codex BLOCKING Codex BLOCKING review on PR #1825 sha 32541a56: 1. (BLOCKING) Q-Refined-Phantom-Composition (c) ratification deferred phantom-carrier predicates without naming the value-level predicate authority. Updated canvas Q-Unit-4 RATIFICATION row to explicitly name: 'predicates re-attach at value-typed Int/UInt level via where-sugar (e.g., range(min: 0) per current dsl/std/types.dag precedent)' when value-typed integration lands. 2. (BLOCKING) Worker brief option-c reframe didn't sweep the audit receipt §5 (Carrier dissolves the bridge). Updated to consistently apply (c) shape — dimensional semantics ride on Quantity tag at Measure layer; value-level predicate authority deferred; until then, range/gt_zero constraints attach at value-typed Int/UInt via where-sugar per dsl/std/types.dag convention. 3. (NON-BLOCKING) Canvas had #issuecomment-... placeholder for the (c) ratification message ID. Replaced with concrete #issuecomment-4385687075 per dashboard relay header. Brief now names a single value-level authority (Int/UInt where-sugar) for value-range facts; phantom-layer Quantity tag carries only dimensional semantics. P2 boundary discipline maintained. * docs(briefs): S12 RETIRED per Director option (2) ratification Director ratified option (2) at gunbc#828 #issuecomment-4385873... 2026-05-06 post smart-ram-167's substrate-state STOP-AND-ESCALATE: - F2 absorbed by 2026-05-04 routing + #1662 closure (`Result/DivError span.file-keyed` retired) - F8 topical concerns distributed across live rows (Class 5 Gap 3 `bootstrap.rs::std_fixtures()`; Character-level load-set / bootstrap; Filename-sentinel-bridges) with own owners - Doc-discipline goals absorbed by per-Mgr citation paydown routing at gunbc#828 #issuecomment-4385583247 Frontmatter updated to RETIRED with absorption receipt. Worker (smart-ram-167) pin freed. Director-side acknowledgment of Substrate Mgr's option (2) recommendation: "Substrate Mgr's option (2) recommendation is the right move structurally. Most Mgrs default to 'synthesize work to fill the brief' when canvas-vs-HEAD mismatch surfaces. Recommending retirement when the work is genuinely absorbed is harder discipline." * docs(briefs): S7 PR-F (BoundDeclaration consumer + ReferenceModel<T>) worker brief Per cascade-clearance trigger fired post-#1782 merge 2026-05-06. loyal-wolf-828 (#1764) acknowledged S7 dispatch with substrate-state pre-flight grep (gunbc#1764 #issuecomment-4385872...) and surfaced await-brief posture. This brief satisfies that prerequisite. Worker pre-flight inventory absorbed: - BoundDeclaration substrate landed (substrate.dag StaticBound + PlatformDependent); partial BoundDeclarationView consumer in fold.rs (ScratchIntExamples scope; doc-explicit partial) - ReferenceModel<T> NOT yet in dsl/std/ (substrate-fact-introduction required; design-emission-model.md §Q2 framing) Phase-1: BoundDeclaration consumer broadening to full design-emission-model.md surface (u128 / isize / usize / walker arms / pilot mirror). Phase-2: ReferenceModel<T> P1 substrate-fact-introduction with DFS-of-concept-DAG + Practice 4 in-source checkpoint comment + named consumer demand (Grounding G1). Phase-3: cross-program handoff to Grounding Mgr (#1745) for G1 (T-Ground-Rust Phase 1). Closure predicate: unblocks Grounding T-Ground-Rust Phase 1.

Brief reframes Slice 2.5 from S-sized (primitive + 1 consumer) to L-sized (predicate registry + PB-1 shim retirement). 5 deliverables: 1. gt_zero primitive predicate 2. Predicate registry infrastructure (resolver-side substrate-fact-introduction) 3. PB-1 shim retirement (span.file=='dsl/std/types.dag' special case dissolves) 4. Migration of existing types.dag predicates (range, pattern, etc.) 5. PositiveInt = Refined<Nat, gt_zero> consumer update Per Director hard scope bars: no parallel predicate-resolution path; no per-call-site special-casing; PB-1 shim retirement non-negotiable in same slice. Single PR per Path 3 RATIFIED. Discipline anchors: feedback_construction_over_ratchets (PB-1 shim is bridge); feedback_dissolve_bridges (registry is structural fix); feedback_no_textual_enforcement_bridges (file-path special-case is anti-pattern shape); P1 substrate-fact-introduction procedure. Worker pin proud-lynx-311 — Director pre-cleared on pre-flight DFS context. PR #1840 (partial Slice 2 — NonNegativeInt = Nat) MERGED at 16:54Z; Slice 2.5 dispatchable immediately on this brief landing. * docs(briefs): Slice 2.5 audit receipt — Mgr independent grep parallel-verifies worker DFS Codex BLOCKING review on PR #1845 sha 2d230949 flagged: external PR receipt absorbed as live substrate state without re-grepping local std declarations at brief authoring time. Authority receipt §1 cited proud-lynx-311's pre-flight DFS as authority but didn't record Mgr-side independent verification. Updated audit receipt §1 + §4 to record Mgr's independent grep at HEAD as parallel verification: - gt_zero zero matches in dsl/std/ + src/v3/ (verified) - NonNegativeInt = Nat at dsl/std/integer.dag:133 (#1840 land) - PositiveInt = Int where range(min: 1) at dsl/std/types.dag:255 - PB-1 shim doc-block confirms bridge-text framing - Predicate registry confirmed not present Worker DFS remains the dispatch-time discipline (substrate-state grep at dispatch); Mgr's independent grep is parallel verification, not substitute. Per Director's pattern note at gunbc#828 #issuecomment-4390199218 + #issuecomment-4390333451: dispatch-packet authoring discipline includes Mgr-side substrate-state-grep, not just relay of worker findings. * docs(briefs): Slice 2.5 brief — Int extensibility scope-bound; lower.rs cites anchored openai-pro REQUEST_CHANGES on PR #1845 sha 2d230949 flagged 2 issues: BLOCKING — P1 modeling faithfulness / substrate scope leak: `gt_zero` Int-side extensibility was left to 'worker judgment if generalization cheap'. Per feedback_construction_over_ratchets: don't speculatively extend predicate-carrier compatibility ahead of named consumer demand. Reframed to **EXPLICITLY OUT-OF-SCOPE** for Slice 2.5; Nat-only registration. Future Int-side consumer surfaces as separate substrate-fact-introduction (P1 procedure) brief with own consumer-demand receipt. NON-BLOCKING — citation discipline self-violation: 3 instances of bare `lower.rs:821-835` line-range citations contradict the brief's own 'no bare :NNN' requirement at line 211. Converted to function-name anchored form: `src/v3/compiler/src/lower.rs` (`lower_type_alias_refinements_phase` doc-block). Both findings absorbed; no parallel scope ambiguity remains; brief now self-consistent on citation discipline. * WIP: R3 Substrate * docs(briefs): Slice 2.5 brief — audit-receipt cites converted to declaration-name anchors cursor APPROVE_WITH_COMMENTS on PR #1845 sha ebf6ac12 noted citation self-inconsistency: audit-receipt section §1 + §4 used bare `dsl/std/integer.dag:133` and `dsl/std/types.dag:255` line-number pins despite the brief's own no-bare-:NNN rule. Converted to declaration-name-anchored form: - 'declaration named NonNegativeInt' (with reproducible grep command) - 'declaration named PositiveInt' (with reproducible grep command) - 'lower_type_alias_refinements_phase doc-block' for PB-1 location Brief now fully self-consistent on its own citation discipline. Verified zero remaining .dag:NNN / .rs:NNN / .md:NNN bare cites. * docs(briefs): Slice 2.5 brief — Path (a) RATIFIED carrier+argument contract verification Director Path (a) RATIFIED at gunbc#828 #issuecomment-4390760353 (triage) + #issuecomment-4390794121 (convergence ack): predicate-body lowering with carrier+argument contract verification at lower-time IN SAME SLICE. Placeholder semantics REMOVED from registry path. Codex REQUEST_CHANGES surfaced that registered-predicate-without- contract = silent acceptance per feedback_fail_closed_discipline. Brief reframe absorbs Path (a): Hard scope bar #5 added: - Same-slice carrier+argument-contract verification - Mismatched carrier OR malformed argument → Diagnostic::ResolveError - No 'named but not checked' path remains Scope expansion section added (L → XL): - Predicate-body lowering for all 7 registered predicates - Per-predicate arg-shape validation - Multi-session work acknowledged - Carrier-check at 788d6acb4 retained; predicate-body builds on top Acceptance bullets updated: gt_zero with arg-shape validation + all 7 predicates with carrier+argument contract verification. Director-pinned brief-authoring discipline: dissolution trigger named in a brief authored as substrate-fact-introduction must specify same-slice acceptance, not deferred follow-up.

Co-inhabitance is real (e.g., #[derive(Debug)] line has both rule=derive_for_disj AND span attribution to Foo decl). Rule-mandatory enforces fail-closed structurally; Practice 4 N/A (record, not coproduct). 2.

Field-path identity threading: render_named_template call sites receive template values extracted from binding structs; field-path may not be carried alongside the value at emission time. New STOP trigger flags this as substrate-cascade if threading isn't structurally possible (typed template-with-rule-path or DeclarationRef carrier needed). 2. Read domain coverage gap: Lens<C>.read is per-Behavior; emitted output also includes declarations + program scaffold. Acceptance scope explicitly narrowed to Behavior-attributable lines only; declarations + scaffold provenance out-of-scope (separate substrate cascade if surfaced).

Replaces four line-number references in r3-426-sfp-subdoc-rename-and-author-worker.md (lines 16, 28, 58, 85) with prose-anchored locators citing the section anchor + bullet text. The other PB-lane briefs codex flagged (r3-pb-runtime-equivalence- corpus-seed-audit.md, r3-pb-t-fixedpoint-worker.md) belong to neat-bear-351's lane and are not in this PR's scope; will route separately. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(briefs): correct L6 type count + r3-435 dual-path retirement receipt Per openai-pro review on PR #1782 (sha c2512cde): 1. L6 brief said acceptance ratchet asserts "five types" exist but declares six (ShapeATarget, FormAxis, BehaviorAxis, MethodTemplateContractKey, EmissionCell, EmissionPathProjection). Updated both occurrences to enumerate all six explicitly. 2. r3-435 brief authorized both Path A (typed-AST reader, deletes IntegrationRsScan) and Path B (scanner widening with Char state), but retirement receipt language only covered Path B. Updated ROADMAP/ledger retirement and authority-audit step 5 to cover both authorized dissolution paths. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(briefs): L6 second 'five types' site + T-E-P lookup-gate authority Per cursor review on PR #1782 (sha 2072b986): 1. L6 brief acceptance bullet at :131 still said "five types" while the parenthetical and the Slice step at :117 said six. The prior fix only caught one of two sites; corrected the second. 2. T-E-P brief `e_p_call_pattern_lookup_authoritative` acceptance named only `lower_call_pattern` as "the only route from call site to LoweringTarget" — but Phase 2 explicitly requires lenses route through `per_call_pattern_at` (the L-7 single- authority lookup), NOT `lower_call_pattern` (compiler-internal). Acceptance text rewritten to name `per_call_pattern_at` as the consumer-facing gate and clarify `lower_call_pattern`'s internal-only scope. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(briefs): strengthen L6 ratchet from count-parity to per-row bijection Per openai-pro REQUEST_CHANGES on PR #1782 (sha 2072b986): the L6 acceptance ratchet asserted only row-count parity between emission_path_projections and the union of MethodTemplateContract rows. Count parity permits duplicate projection keys and missing source rows — the bridge from list-non-empty proxy to per-row projection would not be mechanically proven. The whole point of introducing MethodTemplateContractKey { target, dag_method } is to provide 1:1 row identity. Rewrites the ratchet to assert per-row bijection: every MethodTemplateContract source row has exactly one matching EmissionPathProjection row by key; every projection key resolves to exactly one source row; duplicate projection keys fail closed. (The other openai-pro BLOCKING finding — T-E-P e_p_call_pattern_lookup_authoritative naming the wrong authority — was already fixed at 6282a0704; the review citation was against the pre-fix sha 2072b986.) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(briefs): split L6 ratchet into slice-active vs deferred-activation gates Per BLOCKING inline review on PR #1782 at d92459423: the prior bijection ratchet was unsatisfiable as authored. The *_method_template_contracts lists at HEAD (rust/python/go) are non-empty; shipping emission_path_projections: [] alongside a strict bijection requirement means the bijection cannot pass when the slice lands — source rows would be uncovered. Prior text incorrectly said "vacuously true on the empty source set" — the SOURCE set isn't empty, only the projection set is. Splits the ratchet into two gate categories: - Slice-active gates: types/data shape exist + empty-state predicate (emission_path_projections == []). - Deferred-activation gate: per-row key bijection, authored as a test scaffold by this slice but #[ignore]'d (or feature-gated on len > 0) until Grounding's follow-up populates rows. On activation, asserts the bijection over the populated set. This honors P1 doc faithfulness: the slice's acceptance contract is satisfiable as authored, and the bijection becomes the load-bearing gate the row-population PR satisfies. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(briefs): require L6 bootstrap enrollment to honor P2 facts-flow-forward Per BLOCKING inline review on PR #1782 at L6:34: the slice authored src/v3/std/cross_target_coverage.dag but never required enrolling it in the bootstrap/load authority. Without enrollment the file is dead-letter on disk and EmissionPathProjection can be absent from the downstream Dag — silent P2 facts-flow-forward violation. Adds a new Slice step 2 requiring a cross_target_coverage field on BootstrapFixtures in src/v3/std/extdeps_bootstrap_fixtures.dag mirroring the *_method_template_contracts enrollment pattern, plus a loader-visibility ratchet. Renumbers subsequent Slice steps. Adds matching Acceptance bullet.

Live rule per docs/modeling-discipline.md:131-134 is the "What to check" checkpoint-comment requirement under Practice 4 (coproduct dissolution). Updated the S3 reference to cite that line directly and drop the stale "Step 4 of type-introduction checklist" wording. S2/S8/S9 already use bare "Practice 4" without the stale steps wording. S1 (committed earlier today) does not contain the stale phrase. S6 (pre-existing brief flagged by reviewer as carrying the same pattern) is out of this branch's scope; flag for separate paydown. * docs(briefs): sweep stale Practice 4 citations corpus-wide Codex review on PR #1782 flagged the stale "Step 4 of the type-introduction checklist" wording — no such checklist exists in docs/modeling-discipline.md. The live rule is the "What to check" checkpoint-comment requirement under Practice 4 (coproduct dissolution) at docs/modeling-discipline.md:131. Sweep across docs/ found 2 additional briefs carrying the stale phrasing (S3 fixed previously at 9db003d40): - docs/briefs/r3-l6-emission-path-projection-substrate-worker.md - docs/briefs/r3-x1b-s1-transform-dispatch-substrate-worker.md Both updated to cite the live rule directly. Verified zero remaining "type-introduction checklist" or "Step 4 of the" references in docs/ tree. * docs(briefs): add Practice 4 citation discipline note to authoring checklist Per parent inbox status flag at gunbc#828 #issuecomment-4385346221: add a Citation discipline section to brief-authoring-checklist.md naming the correct shape — Practice 4 (coproduct dissolution) + "What to check" rule at docs/modeling-discipline.md:131 — and calling out the stale "Step 4 of the type-introduction checklist" phrasing as a failure mode. References the corpus sweep at 2dc92f34f. Prevents future briefs that copy old templates from re-introducing the stale citation pattern. * docs(r3): cascade work post-Director ratification — S1 worker, R4 routing, Unit/Quantity canvas Per Director ratification at gunbc#828 inbox response 2026-05-06 (zesty-bear-812): 1. S1 Q1+Q2 RATIFIED → author S1 gap-test representative worker brief (`r3-substrate-s1-gap-test-representative-worker.md`). Dispatchable on T-E-P Phase 1 + E6-G0d landing; closes ledger row #61. 2. S2 Q2 RATIFIED (option-(b) T-LBP narrowing) + S3 + S8 deferrals → R4 carve-out routing ledger (`docs/r4-carve-out-routing.md`). Captures C1 (parallelism lens), C2 (effect_enum lens), C3 (register narrowing), C4 (deferred MachineConstraint axes), C5 (rounding-mode product extension), C6 (Unit/Quantity). Cascade messages to Verification / Grounding / Debt-Paydown Mgrs. 3. S9 Phase-3 dimensional refinement boundary → Unit/Quantity carrier canvas (`r3-substrate-s9-unit-quantity-carrier-canvas.md`). Surfaces Q-Unit-1..5 for Director ratification: carrier name, 2-axis vs 3-axis Phase-1, Duration/Seconds collapse, Refined composition order, Practice 4 classification. Updates §1.8 ledger receipts for carved items; R3 closure receipts treat carved items as explicitly-deferred (not drift). * docs(briefs): citation-discipline fix-forward — anchors/quotes, not line numbers Director redirect at gunbc#828 #issuecomment-... noted the citation paydown's replacement form (`docs/modeling-discipline.md:131`) is the same drift class as the original fabricated-step error. Bare line numbers shift silently on any doc edit above the cited line. Generalized fix: - brief-authoring-checklist.md "Citation discipline" section rewritten to prohibit bare line-numbers across ALL cross-doc references (modeling-discipline.md, r3-program-plan.md, r3-structure.md, INVARIANTS.md, MODELING.md, etc.). Use section anchors (#section-name) or rule-text quotes. - 3 briefs that swapped in :131 (S3, S6, X1B) re-converted: - docs/modeling-discipline.md#4-coproduct-dissolution anchor - "What to check" rule quoted inline (self-contained) Brief-authoring-checklist failure-mode section names both vectors (fabricated step + bare line numbers) and references both sweep commits in audit trail. Broader cross-doc citation sweep across briefs I authored on this branch (frontmatter authority-docs lists, body prose) is recommended per Director note — flagging as separate paydown task; this commit closes the immediate recurrence vector. * docs(briefs): fix unfaithful Int=AbelianGroup<Nat> + sweep stale 'Step 4' refs Per openai-pro review on PR #1782 sha 0ecd4818 (gunbc#1782 #...): BLOCKING fix (P1 modeling faithfulness): - S9 + S3 directed workers to model `Int = AbelianGroup<Nat>`, but Nat is not an Abelian-group carrier (additive inverses not representable). Reframed: - `Int` is the additive Abelian group on integers (carrier Z); `Nat` is a commutative monoid under addition. - Algebraic relationship is **explicit group-completion**: `Int ≡ GroupCompletion<CommutativeMonoid<Nat>>` — NOT `AbelianGroup<Nat>` parameterization. - Worker either models `Int` directly as `AbelianGroup` (terminal Abelian-group instance) OR introduces explicit `GroupCompletion<M>` substrate carrier; decision lands in Phase-1 PR per P1 procedure. - S3 cross-reference + Phase-4 algebra-axis preservation note reframed accordingly. NON-BLOCKING in-PR cleanup (Practice 4 citation discipline): - 6 briefs still carrying stale 'Practice 4 Step 4' wording (r3-coproduct-1/2/3, r3-l6, r3-t-e-p, r3-x1b) updated to use the section anchor (`docs/modeling-discipline.md#4-coproduct-dissolution`) + inline rule-text quote ("What to check") form per the citation discipline established in `b4cae5299`. Closes both findings from openai-pro review. * docs(briefs): Q-Unit-1..5 RATIFIED — apply Scale.Unit→One rename + ratification banner Director ratified Q-Unit-1..5 at gunbc#828 #issuecomment-... 2026-05-06 (zesty-bear-812). All 5 questions ratified; one rename required: - Scale enum's `Unit` value collides with outer `Unit<Q, S>` carrier name (`Unit<Time, Unit>` is shadowing-confusing). Rename to `One`. - Duration ≡ Unit<Time, One> (collapses with Seconds per Q-Unit-3). - Milliseconds ≡ Unit<Time, Milli>. Canvas updated: - Top-level RATIFICATION banner records all 5 ratifications + rename - Scale enum: `Unit` → `One` (with inline rename receipt) - Sketch product expansions use `Unit<Time, One>` / `Unit<Time, Milli>` - Phase-3 reframe table products updated - Q-Unit-3 prose collapse reference updated Subsequent worker brief authoring (Unit/Quantity carrier landing post-prerequisite) inherits the renamed shape. * docs(briefs): Unit/Quantity carrier worker brief — Q-Unit-1..5 RATIFIED Worker brief consumes the ratified Unit/Quantity canvas (`5f22fd06e` ratification banner). Phase-1 lands `Unit<Q, S>` + `Quantity` + `Scale` declarations at the ratified shape (Scale's `One` value per Q-Unit-1 rename). Phase-2 reframes S9 Phase-3 dimensional refinements (Duration / Seconds / Milliseconds) to outer-Refined / inner-Unit composition per Q-Unit-4 RATIFIED. EpochMs deferred to R4 C6 (Aspect-axis follow-up). Practice 4 marks pre-determined per Q-Unit-5: `Unit<Q, S>` 🟢 PRIMITIVE; `Quantity` + `Scale` 🟡 SCAFFOLD with "consumed by ≥1 emission rule" dissolution trigger. Cross-program handoff to Grounding Mgr (#1745) for dimensional emission consumption documented. Worker pin TBD — dispatchable when idle pool refreshes. * docs(briefs): S9 Phase-1 reframed — Int landed at #1466; UInt-only migration Per proud-lynx-311 dispatch ack at gunbc#1739 #issuecomment-... 2026-05-06: re-grep at HEAD revealed substrate state diverges materially from S9 brief's "Option A vs B decide" framing. Reality check at HEAD: - `dsl/std/integer.dag:55` already carries `type Int = AbelianGroup<GroupCompletion<Nat>>` per Slice 3 PR #1466 / commit `4ba0a6d04`. Single-authority Q6 audit doc at `docs/audit/t-numeric-construction-group-completion-6q.md` ratified this shape and explicitly rejected the compact form. - `dsl/std/integer.dag:56` still on legacy `type UInt = UInt64` alias; UInt migration is the actual Phase-1 worker scope. Brief Phase-1 step 1 reframed: Int landing acknowledged; worker confirms HEAD match. Phase-1 step 2 reframed: UInt migration target named (`type UInt = CommutativeMonoid<Nat>`); fixed-width rows preserved per existing legacy-rows policy. Historical Option A vs B framing kept as note (superseded). Confirmed S9 dispatch ack from worker; UInt-only Phase-1 PR is in-scope. Emission entries deferred per S3 (valiant-ant-72 pre-landing); Phase-2 deferred per S8 (quiet-boar-160 pre-landing). * docs(briefs): fix two BLOCKING citation drift items per codex review Codex review on PR #1782 sha 5f22fd06 flagged two authority-receipt gaps: 1. brief-authoring-checklist.md:118 — `<this-commit>` placeholder in the failure-mode section was unverifiable post-merge. Replaced with `b4cae5299` (the actual anchor/quote conversion commit). 2. r3-378-http-path-helper-fail-open-worker.md:84 — `INVARIANTS.md C-8 fail-closed` cited without anchor or rule-text quote, in violation of the citation discipline added in this PR. Converted to `INVARIANTS.md#p3-fail-closed` (P3 heading anchor) + inline rule-text quote naming P3 + C-8. PR's own discipline now consistently applied across the diff. * docs(briefs): sweep bare .md:NNN citations in Substrate-Mgr-authored briefs Per Director recommendation in citation-discipline thread (gunbc#828 follow-on): bare line-number references drift silently. Swept 19 remaining instances across 5 briefs I authored on this branch: - docs/briefs/r3-substrate-s1-q-class-2-chain-break-gap-test-canvas.md - docs/briefs/r3-substrate-s1-gap-test-representative-worker.md - docs/briefs/r3-substrate-s2-t-lbp-scope-calibration-canvas.md - docs/briefs/r3-substrate-s3-machine-constraint-carrier-worker.md Conversion: bare `file.md:NNN` → `file.md §"Section name"` form. Stable; survives doc edits; human-readable. Section names per HEAD heading audit. Verification: `grep -nE '.md:[0-9]+' docs/briefs/r3-substrate-*.md docs/r4-carve-out-routing.md` returns zero results in Substrate-Mgr-authored scope. Broader corpus scope (~232 references across non-Substrate briefs) remains as separate paydown task. * docs(briefs): fix BLOCKING + NON-BLOCKING items per openai-pro review on a462f007 Three findings addressed; 2 BLOCKING + 1 NON-BLOCKING: BLOCKING — R3/R4 dual authority for Unit/Quantity carrier: R4 carve-out C6 narrowed from "Unit/Quantity carrier landing" (deferred all of it) to **"Aspect-axis (PointKind) follow-on for EpochMs and instant/rate-shaped refinements only"**. The 2-axis Measure<Q,S> carrier landing IS in R3 per Q-Unit-1..5 RATIFIED; only the Aspect axis (PointKind = Magnitude | Instant | Rate) carves to R4. Cascade-message C6 reference + R4 program- plan input list updated to match. Cross-Mgr message clarifies Grounding consumes 2-axis dimensional refinements in R3. BLOCKING — Locked design partially applied (Scale.Unit→One rename in canvas alternate-sketch sections): - Canvas line 105-108 alternate sketch ("Open question: Instant vs Duration axis") still used pre-rename `Unit` Scale value; added pre-ratification disclaimer marking the section as deferred to R4 C6 + noting `Unit` is pre-rename - Canvas line 163 Q-Unit-3 collapse note: `Scale = Unit` → `Scale = One` (BLOCKING — bare line-numbers in S1 canvas frontmatter): NOT APPLICABLE — already fixed at sweep commit 127287a66 prior to review; reviewer was on sha a462f007 pre-sweep. NON-BLOCKING — placeholder receipts: - brief-authoring-checklist.md `#issuecomment-...` → concrete ID 4385393971 (Director's anchor-discipline reply) - r3-substrate-unit-quantity-carrier-worker.md (3 occurrences) + canvas RATIFICATION banner: `#issuecomment-...` → concrete ID 4385412256 (Q-Unit ratification reply) - `<this-commit>` placeholder in checklist already fixed at 5be1c99f2 Verification: zero `#issuecomment-...` or `<this-commit>` placeholders in docs/briefs/ + docs/r4-carve-out-routing.md. * docs(briefs): codex BLOCKING review fixes — Practice 4 source-level + policy scope Three BLOCKING findings on PR #1782 (codex sha b913e2f4): 1. **Citation-discipline policy scope**: addressed by scoping the rule prospectively to briefs landing after the policy commit (`b4cae5299`). Pre-existing corpus references are flagged as paydown but NOT individually blocking; coordinated single-PR sweep is the right paydown shape. Substrate-Mgr scope already swept at `127287a66`. 2. **R4 C6 reconciliation**: already fixed at `6e5a5481a` (R4 C6 narrowed to Aspect-axis follow-on for EpochMs only; 2-axis carrier landing IS in R3). Codex sha b913e2f4 was pre-fix. 3. **Practice 4 source-level vs PR-body conflation**: corrected. Acceptance bullet for Unit/Quantity worker brief now requires inline checkpoint comments on the LIVE declarations in `dsl/std/units.dag` (load-bearing artifact per `docs/modeling-discipline.md#4-coproduct-dissolution` "What to check"). PR-body summary is supplementary, not substitute. Closes the review's reconciliation gates. * docs(briefs): absorb Q-MachineConstraint + Q-Unit-1-Recanvas ratifications Two major Director ratifications absorbed: 1. Q-MachineConstraint-Carrier RATIFIED at gunbc#828 #issuecomment-4385530115 (Brian directive 2026-05-06: "universal substrate, ratify defaults"; PR #1817 queued). 6 sub-decisions: - MachineWidth<bits> only for R3; defer RegisterClass / EndianMode / Alignment / signedness post-R3 - Parametric Compose<Algebra, MachineConstraint> type-level interaction shape (lookup-maps REJECTED — AlgebraMachineProduct record-keyed table form retracted) - Int<64> ≡ Compose<AbelianGroup, MachineWidth<64>> (algebra-side options A and B preserve interaction semantics) - Real<64> ≡ Compose<ApproximateField<Rational>, MachineWidth<64>> (algebra approx + machine approx as independent composing axes) - ≥3 pairs is minimum, not target - UNIVERSAL substrate: every target carries machine-constraint facts; targets without native machine-width semantics handle omission at Grounding-level discharge (target-conditioned lowering NOT target-conditioned substrate) Reframed: S3 brief Phase-1, S3 Phase-3/4 emission entries, S8 Phase-1/2/3 (ApproximateField<Real> → ApproximateField<Rational>; AlgebraMachineProduct → Compose<...>), S9 emission entries. 2. Q-Unit-1-Recanvas RATIFIED Measure<Q, S> at gunbc#828 #issuecomment-4385539791. valiant-ibex-312's substrate-state grep caught Unit<Q, S> collision with kernel Unit at dsl/std/types.dag:176; Director ratified Measure<Q, S> as outer carrier name (conventional in scientific computing; no dsl/std/ collision). Reframed: Unit/Quantity worker brief throughout (Unit<Q,S> → Measure<Q,S>; dsl/std/units.dag → dsl/std/measure.dag); canvas spec sections + sketch products (Refined<Measure<Time, ...>...>); R4 carve-out C6 with informal/formal name disambiguation note. Both rename + reshape are now consistent across S3 / S8 / S9 / Unit-Q briefs + canvas + R4 routing. Workers (valiant-ant-72 on S3, quiet-boar-160 on S8, proud-lynx-311 on S9, valiant-ibex-312 on Unit-Q) all dispatch against the ratified shape. * docs(briefs): S11 Slice C worker brief — ROADMAP :425 retirement post-#1801 Cascade-clearance trigger fired post-#1801 (Slice B) merge 2026-05-06.

Q-Unit-4 outer-Refined / inner-Measure composition is preserved as **conceptual model**; the literal `Refined<Measure<...>, predicate>` form is **deferred to value-typed-integration follow-up** when substrate gains Refined<> as first-class type expression and dimensional refinements get value-typed integration. Updates: - Canvas RATIFICATION banner Q-Unit-4 row reframed to "conceptual model; literal form deferred" - Canvas Phase-3 reframe table: Duration / Milliseconds drop the Refined<...> wrapper; rely on Quantity tag - Worker brief Phase-2 prose + reframe table + Acceptance bullet all reflect deferred-literal-form posture valiant-ibex-312 unblocked to proceed with Phase-2 (Grounding handoff doc) per the (c)-shaped Acceptance. * docs(briefs): S12 F2 + F8 doc-sharpening worker brief — post-#1820 cascade #1820 (Slice C) merged 2026-05-06; ROADMAP :425 row Retired closes the prose-reference paydown program.

Final landed form preserves full `CommutativeSemiring<Magnitude>` surface — Nat IS a commutative semiring (addition + multiplication + 0 + 1). Algebra-side label for UInt is CommutativeSemiring, NOT CommutativeMonoid (corrects my earlier dispatch labeling). S9 Phase-1 step 2 marked LANDED with merge ref. Phase-1 step 3 emission entries reframed: - Int<N> ≡ Compose<AbelianGroup, MachineWidth<N>> - UInt<N> ≡ Compose<CommutativeSemiring, MachineWidth<N>> Worker discipline + reviewer caught a substrate-state error in my brief framing; brief now matches landed reality. * docs(briefs): fix contradictory (c) guidance in Unit/Quantity worker brief Codex BLOCKING review on PR #1825 sha 1bce0418 caught a real contradiction: brief Phase-2 prose at lines 115-118 stated "predicates do NOT attach at the Measure (phantom) layer" per Q-Refined-Phantom-Composition (c) RATIFIED, but immediately following paragraph at lines 130-132 still said "Refined predicate non_negative applies at the Measure-typed level" — left over from the original Q-Unit-4 framing. Updated lines 130-137 to consistently apply (c) shape: predicates deferred to value-typed-integration follow-up; dimensional semantics ride on Quantity tag at Measure layer; worker authors 3 in-scope refinements WITHOUT predicate at this layer. P2 boundary discipline restored: brief now gives single-authority guidance for Phase-2 substrate landing. * docs(briefs): name predicate authority + concretize ratification ID — codex BLOCKING Codex BLOCKING review on PR #1825 sha 32541a56: 1. (BLOCKING) Q-Refined-Phantom-Composition (c) ratification deferred phantom-carrier predicates without naming the value-level predicate authority. Updated canvas Q-Unit-4 RATIFICATION row to explicitly name: 'predicates re-attach at value-typed Int/UInt level via where-sugar (e.g., range(min: 0) per current dsl/std/types.dag precedent)' when value-typed integration lands. 2. (BLOCKING) Worker brief option-c reframe didn't sweep the audit receipt §5 (Carrier dissolves the bridge). Updated to consistently apply (c) shape — dimensional semantics ride on Quantity tag at Measure layer; value-level predicate authority deferred; until then, range/gt_zero constraints attach at value-typed Int/UInt via where-sugar per dsl/std/types.dag convention. 3. (NON-BLOCKING) Canvas had #issuecomment-... placeholder for the (c) ratification message ID. Replaced with concrete #issuecomment-4385687075 per dashboard relay header. Brief now names a single value-level authority (Int/UInt where-sugar) for value-range facts; phantom-layer Quantity tag carries only dimensional semantics.

Same finding as smart-ram-167 STOP at gunbc#1759 #issuecomment-4392696623; Reading C surfaced to Director at gunbc#828 #issuecomment-4392780871. 3. Rust-primitive-full-coverage brief (Finding #3 — BoundDeclaration not wired into TargetIntegerInhabitanceBound row surface): reframed Deliverable 2 to target the actual carrier `v3.std.emit_model::TargetIntegerInhabitanceBound` (used by `TargetIntegerTypeInhabitance` rows in src/v3/spec/rust.dag lines 169-207). Two paths surfaced: Option (i) wire BoundDeclaration into TargetIntegerInhabitanceBound; Option (ii) populate via existing variants if PlatformDependent already exists on the live carrier. Worker DFS at dispatch picks. Deliverable 3 retargeted to TargetIntegerTypeInhabitance rows (the actual surface). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * rust-primitive-full-coverage: codex inline confirms TargetIntegerInhabitanceBound has no PlatformDependent variant — Option (ii) infeasible; carrier refactor REQUIRED Codex BLOCKING inline at PR #1910 line 65 (sha 98507c432) verified at HEAD: TargetIntegerInhabitanceBound = BoundUnspecified | StaticBoundFact(IntInterval). No PlatformDependent variant. Earlier brief framing of Option (ii) (populate via existing variants) was infeasible. Brief reframed: carrier refactor is required (not optional). Two structural shapes for the refactor — (i.a) embed BoundDeclaration (Mgr recommendation; single-authority discipline) vs (i.b) extend variant set with PlatformDependent. Existing 5 rows migrate either way; bootstrap snapshot semantic-equivalence non-negotiable. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * emission-provenance lane: T-Rule-Enumeration RETIRED + Lens brief revised per Director Reading C Director Reading C RATIFIED at gunbc#1739 #issuecomment-4392797954 (2026-05-07): - Q1: T-Rule-Enumeration retires (substrate gap was phantom; ~37 *SyntaxBinding/*OpsBinding field paths already provide enumeration per smart-ram-167 substrate-state-grep at gunbc#1759 #issuecomment-4392696623) - Q2: Lens<EmissionProvenance> dispatches now (no precondition gate) - Q3: EmissionRule = String of field-path (per feedback_reason_not_label) Actions: - Delete docs/briefs/r3-substrate-t-rule-enumeration-worker.md - Lens brief: replace T-Rule-Enumeration precondition gate with Reading C absorption section; EmissionRule = field-path String; cementing test verifies field-path round-trip; STOP triggers retargeted to *SyntaxBinding field-set divergence Worker pin: smart-ram-167 (Mgr discretion per Director ratification; fresh context on field-path enumeration). valiant-ibex-312 stays on Rust-primitive-full-coverage / T-Interval-Representation. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * emission-provenance lens brief: absorb codex BLOCKING bundle (sha 4229cd09 post-merge findings) Two findings from codex bundled review on now-merged PR #1910 sha 4229cd09 land as brief revisions for the in-flight smart-ram-167 authoring cycle (PR #1928): 1. Field-path identity threading: render_named_template call sites receive template values extracted from binding structs; field-path may not be carried alongside the value at emission time. New STOP trigger flags this as substrate-cascade if threading isn't structurally possible (typed template-with-rule-path or DeclarationRef carrier needed). 2. Read domain coverage gap: Lens<C>.read is per-Behavior; emitted output also includes declarations + program scaffold. Acceptance scope explicitly narrowed to Behavior-attributable lines only; declarations + scaffold provenance out-of-scope (separate substrate cascade if surfaced). Acceptance bullet retargeted to "Behavior-attributable span-Some + Behavior-attributable span-None" rather than full-emission coverage. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * rust-primitive-full-coverage: revert to Option (ii) — Mgr ratification-state-grep miss caught by valiant-ibex-312 valiant-ibex-312 ratification-state-grep at gunbc#1761 #issuecomment-4393074602 surfaced that origin/main HEAD has TargetIntegerInhabitanceBound with 3 variants including PlatformDependentFact (mirrors BoundDeclaration::PlatformDependent). Earlier brief framing at 4229cd09d was against pre-PlatformDependentFact state per codex BLOCKING reading; main moved since. Option (ii) IS feasible: isize/usize rows populate via existing PlatformDependentFact variant directly; u128 row populates StaticBoundFact with BigInt-widened ExactInterval (Deliverable 1 unchanged). No carrier refactor needed; 5 existing rows untouched. Second Mgr-tier ratification-state-grep miss today (first was symbol-only grep on T-Rule-Enumeration; now stale-codex-vs-current-HEAD on TargetIntegerInhabitanceBound). Worker-tier discipline caught it before sinking time into invasive Option (i.a) refactor. Single-authority concern (parallel-named variants on TargetIntegerInhabitanceBound vs BoundDeclaration) noted as future substrate-fact-introduction; not blocking this slice — explicit-mirror is the existing convention. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * rust-primitive-full-coverage: align Acceptance + Phase ordering + STOP triggers to Option (ii) (resolve codex internal-contradiction finding) codex BLOCKING on PR #1929 sha 14f68b63 caught real internal contradiction: Context section flipped to Option (ii) feasible at 57ae4349b but Acceptance + Phase ordering still referenced BoundDeclaration migration / RustPrimitive bound field refactor from earlier Option (i.a) framing. All sections now consistent with Option (ii): - Phase 4 = no-op (TargetIntegerInhabitanceBound carrier untouched) - Phase 5 = spec/rust.dag rows for isize/usize via existing PlatformDependentFact variant - Phase 6 = u128 row via StaticBoundFact(IntInterval) + ratchet update - Acceptance retargeted to row-population shape (no carrier refactor; existing 5 TargetIntegerTypeInhabitance rows untouched) - STOP triggers retargeted to TargetIntegerInhabitanceBound variant-set sufficiency at HEAD - Why-bundled rationale rewritten to Option (ii) shape (Phase A widening unblocks u128 StaticBoundFact; isize/usize use existing PlatformDependentFact) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * lens brief: narrow Deliverable 3 verification step 4 to Behavior-attributable lines (resolve codex #2 consistency) codex BLOCKING #2 on PR #1929 sha 812602b4 caught: Acceptance + STOP triggers narrowed to Behavior-attributable lines but Deliverable 3 cementing-test step 4 still said 'every emitted line'. Now consistent — step 4 explicitly scopes to Behavior-attributable subset; declarations + program scaffold OUT-OF-SCOPE per same Finding #2 framing. (codex BLOCKING #1 — claim that PlatformDependentFact NOT on main — is wrong; verified at origin/main HEAD: TargetIntegerInhabitanceBound has 3 variants including PlatformDependentFact. Rebut on PR.)
