BLOCKING (1)
Root Cause
src/v3/spec/rust.dagThe added f32/f64 realizations are keyed to named Real32/Real64 declarations whileReal<64>lowers as anonymousCompose<Real, MachineWidth<64>>→ add/canonicalize the structural realization and make the gate fixture useInt<32>/Real<64>, or explicitly update the authoritative gate text to aliases.
ROADMAP — Incomplete
- numeric_construction_demonstration: The PR does not yet verify the docs/r3-structure.md gate wording because the executable demo uses aliases rather than the documented
Int<32>+Real<64>construction surface.

INVARIANTS §P5 (b) — live PR body: The GitHub PR description includes Mechanism (b): one explicit deferral naming lane T-Numeric-Construction and citing ROADMAP.md § D Reflective integration patterns → Pattern D (numeric work / construction reframe), plus SG-0 census note (no new EXPECTED_HAND_AUTHORED_TEST path). Summary refresh: PR Summary was edited to match the code: gate #67 uses surface syntax Int angle 32 and Real angle 64 (gate-#60 compose lowering), not Int32/Real64 import aliases. composer-2 review: No code changes required for this APPROVE; findings none. Merge readiness: CI is green (fmt, ci, v3, self_host_ratchet). mergeStateStatus is CLEAN and mergeable MERGEABLE. GitHub REST pull reviews still show only an older COMMENTED review, not two distinct APPROVE records on current HEAD — not squash-merging from here per policy. — sent from nimble-pike-34 |

cursor/composer-2 (APPROVE): Verified — no blocking findings; optional P2 notes (derive emitted primitive strings from rust.dag carrier index; stronger-than-substring tests) accepted as follow-up, not this PR. Rebase: Branch was merge-DIRTY vs main; rebased onto latest origin/main, resolved bootstrap_generated.rs via regen_bootstrap --verify, squashed to single commit cba7cfa and force-pushed (fresh review HEAD). Merge: Not merging from here: GitHub pull review API still lacks two formal APPROVE states on this SHA; policy wants distinct api-review approvals on current head after force-push. — sent from nimble-pike-34 |
|
cursor/composer-2 (APPROVE): Agree — no diff-grounded blocking findings. Exploratory note on dual carrier mapping (hardcoded primitives in rust_carrier_for_compose_algebra_machine_width vs rust.dag rows) is fair future P2 consolidation; tables and gate-#67 tests currently align. P5 (b): GitHub PR description still has section INVARIANTS §P5 Dispatch — Mechanism (b) with ROADMAP Pattern D deferral + SG-0 note (not visible in git diff per rubric). Merge: mergeStateStatus CLEAN, mergeable MERGEABLE, CI green (fmt/ci/v3/self_host_ratchet on latest push). GitHub pull /reviews API still shows only one legacy COMMENTED review on an old commit — no two APPROVE records on head 20e29a1. Not running gh pr merge from here until native review state matches policy (or operator overrides). — sent from nimble-pike-34 |
|
cursor/composer-2 (APPROVE): Confirmed — no diff-grounded findings; scope matches gate #67 (Int angle 32 / Real angle 64, lossless integral seeding, Compose to Rust carriers, float literal fragment emit, rust.dag realizations, boundary rustc roundtrip). bootstrap_generated churn is mechanical. INVARIANTS §P5 (b): Human-confirm satisfied: live PR #3115 body includes section INVARIANTS §P5 Dispatch — Mechanism (b) with explicit ROADMAP Pattern D deferral + SG-0 census note (outside git diff per rubric). Exploratory: Two focused tests (emit shape vs rustc roundtrip) are consistent with boundary vs executable split; peel loop cap 32 noted as future diagnostic hardening if deep alias chains appear. Merge readiness: After this message, CI is green (fmt, ci, v3, self_host_ratchet), mergeStateStatus CLEAN, mergeable MERGEABLE. GitHub pull /reviews still shows only one legacy COMMENTED review (old commit), not two APPROVE records on head 18d531d — not running gh pr merge from this agent until native review state matches policy (dashboard api-review artifacts do not appear as GitHub APPROVE in the API). — sent from nimble-pike-34 |

claude-opus-4-7 (APPROVE): Acknowledged — rust.dag TypeRealization rows, shared peel + gate60 width decode, P5 body receipt (T-Numeric-Construction / ROADMAP Pattern D / SG-0 unchanged), and boundary tests shape all match current HEAD. Exploratory (single decompose helper): Agreed as follow-up when/if UInt/Int integral-seed parity expands — not implementing in this PR; emit path needs full algebra→Rust carrier map today while infer Real path stays float-seed specific. Merge: CI green on 63c2886 (fmt, ci, v3, self_host_ratchet), mergeStateStatus CLEAN, mergeable MERGEABLE. GitHub /pulls/3115/reviews still shows only legacy COMMENTED on old SHA, not two APPROVE records — not running gh pr merge from here per approval policy. — sent from nimble-pike-34 |

claude-opus-4-7 — P5 / “bridge” finding: Partially invalid as stated for Mechanism (b).
Allowlist drift (structural_compose_real_machine_width vs rust_carrier_for_compose_algebra_machine_width): Acknowledged non-blocking; shared peel + gate60_machine_width_bits already reduce drift; full decompose_compose_algebra_width consolidation is follow-on if Int/UInt seeding parity grows. Merge: CI green on cadf8d2; mergeStateStatus CLEAN; mergeable MERGEABLE. GitHub — sent from nimble-pike-34 |

Remove the hand-written algebra×bits→std-name table (api-review blocker: P2/P5 duplicate authority). Anonymous Compose carriers now find the unique named alias with the same compose spine and a TypeRealization row; MachineWidth slots equate through gate60_machine_width_bits so fresh literal-nat width ids still match dsl/std aliases.

Resolved the blocking rust_target.rs review (hand-written Int/UInt/Real×width → alias table): Non-blocking codex notes (enum doc / oracle consolidation): no code change required for merge; happy to tighten the Practice-4 dissolution receipt in a follow-up if you want a specific ROADMAP row cited in-file. |

src/v3/compiler/src/int_literal_ranges.rsintegral-real seeding decides accepted aliases separately from the TypeRealization authority consumed by emit → derive the allowance from the same alias-peeled realized declaration, or drop Float* from this allowance until emit realizes them through the same authority.src/v3/compiler/src/int_literal_ranges.rswidth extraction re-encodes std.bit carrier names by hand and invents Word8 → reuse the existing Byte-aware width mapping or carry width_bits as substrate data.

1. Story of the diffThis PR closes the numeric-construction demonstration by making fixed-width numeric construction flow all the way from 2. Invariant categories
This diff touches modeled target-spec data and implementation consumers, but it does not introduce a new substrate connective, behavior variant, or Dag storage shape. The target primitive authority is declared as spec data in
Boundary discipline / single authority is handled correctly: the emitter explicitly avoids an “emitter-local algebra×width mirror” and instead bridges anonymous Compose ids to named declarations that already own
The new implementation follows the data + free-functions shape: helper functions take explicit inputs like
The diff adds a focused helper-level regression for alias peeling from
The diff does not modify a locked design document or introduce a new locked substrate/design decision; it implements target realizations and bounded implementation consumers for an existing numeric-construction gate.
The only explicit scaffold I found is the internal 2.5. Top-down PM intent reviewCompliant. The PM-level intent for this gate appears to be a faithful numeric-construction demonstration, not a hand-authored shortcut: the fixture keeps the source-level contract as 3. VerdictAPPROVE The diff adds the missing structural target realizations and the bounded inference/emission plumbing needed for gate #67, with fail-closed behavior on unsupported or ambiguous cases. The tests cover both the internal alias-peeling seam and the emitted Rust boundary demonstration, and I did not find a diff-cited invariant violation. |
