… under Director ratification
Per Director ratification at gunbc#828 #issuecomment-4392256151
(zesty-bear-812 — "Lens<EmissionProvenance> as another Lens<C>
instance per feedback_lenses_not_passes; Substrate authors instance
carrier; Verification asserts gate") and Brian directive 2026-05-06
chat ("R3 has idle workers under several managers, so we should put
them to work asap").
Brief covers:
- EmissionProvenance C-type with fail-closed discipline
(at least one of source_span / fold_rule present per emitted line
per feedback_fail_closed_discipline C-8)
- Lens<EmissionProvenance> instance per existing Lens<C> 6-field shape
(Director-locked at src/v3/std/lens.dag); shape parity with existing
T-CostLens-Composition Lens<SymbolicCost> precedent
- Cementing test verifying inverse mapping closes (every emitted line
has either populated source_span OR fold_rule; both-absent fails
closed)
- 4 STOP triggers (missing fold-rule names; Lens<C> shape gaps;
third origin class surface; substrate-state-grep mismatch)
- Cross-lane refs to T-LAS (instance becomes consumable via apply_lens
post-T-LAS); Grounding (downstream consumer optional, R3 scope is
instance landing only); T-CostLens-Composition (shape precedent)
- Worker pin candidates: smart-ram-167 OR valiant-ibex-312 (Mgr discretion)
- §1.8 ledger gate #89 emission_provenance_lens_landed (proposed)
Brief is pre-authored per feedback_pre_authored_brief_queue discipline.
Substrate Mgr disposes dispatch readiness at brief-PR-merge time;
adjusts content lightly if substrate state shifts (does not re-author
from scratch).
Forward direction (.dag → diagnostic source-span) already exists
structurally (SourceSpan on every Behavior + Declaration per dag.rs:47-48);
inverse direction (emitted Rust → .dag origin) is implicit in the
fold but not currently exposed as metadata stream. This lens instance
landing exposes it.
PR #1879 (emission-intuition slide) surfaced the gap; visualization
claim benefits from this lens once landed.

Per claude review at sha 3c96212 (PR #1902 #issuecomment-4392308244): 1. Optional<T> canonical shape: PM grep-verified that .dag uses T? suffix (e.g., String? at src/v3/std/anthropic_schema.dag:115-119); named Optional carriers like OptionalDiagnostic exist at src/v3/std/dimensions.dag:41 but generic Optional is T? suffix. Updated EmissionProvenance C-type fields: - source_span: OptionalSourceSpan -> SourceSpan? - fold_rule: OptionalString -> String? Added explicit "Optional shape note" with grep references. 2. STOP trigger #1 (missing fold-rule names) reframed as likely prerequisite-not-mid-implementation-STOP: claude observed that STOP #1 is most likely-to-fire one — really a prerequisite, not a stop-condition. PM grep-verified at authoring-time that fold-rule names are NOT enumerable in src/v3/compiler/src/ (0 hits for RuleName / FoldRule / fn emit_derive). Updated STOP trigger #1 to surface this as PM-side recommendation: Substrate Mgr disposes resolution before worker dispatch (rule-name enumeration substrate as separate brief OR confirm grep was incomplete OR re-scope to land partial-provenance only). Avoids mid-implementation discovery of a hard prerequisite. Both observations are non-blocking per claude verdict (APPROVE) but worth applying for downstream worker quality + Substrate Mgr prerequisite-resolution-before-dispatch.

…brief — status PROPOSAL pending Substrate Mgr canvas Codex BLOCKING at sha 3c96212 (PR #1902) surfaced 3 substantively valid findings; all PM grep-verified before applying. Finding 1 (optional+invariant origin → typed-sum origin) APPLIED: type EmissionOrigin = SubstrateDeclMirror { span: SourceSpan } | FoldRuleAutoEmit { rule_name: String } type EmissionProvenance { emitted_line: Int origin: EmissionOrigin // REQUIRED } The Disj carrier makes "at least one origin class present" structurally true; eliminates the prior optional+runtime-invariant structural recovery pattern. Per feedback_state_space_vs_behavioral_invariants (type enforcement > API enforcement). Finding 2 (Lens<C> read shape category mismatch) FLAGGED: Lens<C>.read: fn(Dag, Behavior) -> Witness<C> per src/v3/std/lens.dag — per-Behavior read. Emission provenance is per-emitted-LINE, not per-Behavior. Real category mismatch. Brief reframed to status: PROPOSAL pending Substrate Mgr canvas. Three reframing paths surfaced for Substrate Mgr disposition: (a) per-Behavior framing (Lens<C>-compatible; narrower scope; doesn't directly support Brian's slide visualization) (b) per-emitted-line instrumentation (NOT a lens; matches Brian's visualization; different substrate shape entirely) (c) withdraw + canvas first; re-author once shape ratified. PM recommendation: (c). Substantive reshape needs Substrate Mgr canvas, not PM tactical pre-authoring. Finding 3 (§1.8 #89 already taken) APPLIED: PM grep-verified §1.8 #89 is `section_ref_substrate_landed` under T-Lens-Application-Surface (already declared 2026-05-06). My citation was wrong. Brief frontmatter retargeted to "TBD — gate authority pending"; cites 3 candidate retarget paths for Substrate Mgr disposition: (a) new gate under T-CostLens-Composition cluster (#37-#40 analog); (b) new gate under T-LAS; (c) deferred until per-Behavior framing ratified. Brief is now NOT dispatch-ready — explicitly PROPOSAL status until Substrate Mgr canvas resolves Finding 2 + gate authority. PM tactical-authority limit acknowledged: emission-provenance is substantively richer than I initially scoped; Substrate Mgr canvas is the right next step, not worker dispatch.

…bitrary String Per codex BLOCKING inline at brief line 57 (sha 3c96212) — same finding-class as parent BLOCKING but more pointed: while my prior fix (commit 0110f73) eliminated the both-absent admittance via typed Disj, FoldRuleAutoEmit { rule_name: String } still admitted arbitrary fold-rule strings. P2 illegal-states-unrepresentable requires typed LangSpec rule ref, not free String. Fix: FoldRuleAutoEmit { rule: LangSpecRule } where LangSpecRule is a typed enumeration of LangSpec emission rules. Now both structural invariants hold by construction: - "at least one origin class is present" (typed Disj over the 2 classes) - "rule names are well-formed LangSpec identifiers" (typed enumeration) This reinforces the rule-name-enumeration prerequisite already cross-relayed to Substrate Mgr at gunbc#1739 #issuecomment-4392435376: LangSpecRule typed enumeration MUST exist as substrate carrier before this brief can dispatch. Substrate Mgr disposes: (a) author LangSpecRule enumeration substrate first; (b) confirm grep was incomplete and rules ARE enumerable elsewhere; (c) brief dispatched only after typed-rule prerequisite lands. Per feedback_state_space_vs_behavioral_invariants — eliminates structural-recovery pattern by making invariants type-true rather than runtime-asserted. Brief stays status: PROPOSAL pending Substrate Mgr canvas on Finding 2 (Lens<C> read-shape category mismatch) + Finding 3 (gate retargeting).

… just granularity) Per codex BLOCKING inline at line 73 (sha c375eba): the Lens<C> read shape mismatch is deeper than initially framed. Initial frame: "Lens<C> is per-Behavior; goal is per-emitted-line — category mismatch on granularity." Deeper frame (PM grep-verified): Lens<C>.read domain is `Behavior = Value | Transform | Branch` per src/v3/std/substrate.dag:465. The brief's acceptance surface includes lines from: - Declaration-origin (e.g., pub enum Sum<A,B> from .dag type Sum declaration; pub struct HttpError from type HttpError declaration) - LangSpec auto-emits (e.g., #[derive], impl X { is_left }, impl X { new }) Declarations are at src/v3/std/substrate.dag:235 — structurally separate from Behaviors. Auto-emits have no .dag source at all. Both are OUTSIDE Lens<C>.read's domain entirely. So the mismatch is structural at TWO axes simultaneously: - Granularity: per-Behavior (lens) vs per-emitted-line (goal) - Domain coverage: Lens<C> can only read Behaviors; brief's acceptance includes Declaration-origin + auto-emits which Lens<C> structurally cannot see Reframing paths revised (deeper): (a) Per-Behavior, narrow domain — Lens<C>-compatible, EXCLUDES Declaration-origin + auto-emit lines entirely; very narrow; doesn't support Brian's visualization (b) Per-emitted-line instrumentation, NEW substrate — NOT a lens; requires substrate-fact-introduction (P1 procedure); matches visualization need (c) Withdraw + canvas first — stronger PM recommendation given the deeper mismatch PM-side stance: brief stays status: PROPOSAL pending Substrate Mgr canvas. The Lens<C> framing isn't just narrow; it's structurally insufficient for the brief's acceptance surface. Substantive reshape needs Substrate Mgr canvas + Director ratification on the right shape. Per feedback_corrections_must_grep_verify_source — both axes of the mismatch grep-verified: - Behavior shape at src/v3/std/substrate.dag:465 (3-variant Disj) - Declaration shape at src/v3/std/substrate.dag:235 (separate type) - Lens<C>.read at src/v3/std/lens.dag (per-Behavior fold) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Closing — obsolete branch artifact post-#1902 squash-merge Branch This PR was dashboard-auto-attached because the branch hasn't been synced with main and shows a divergence (brief file ±49 lines vs squashed version + bootstrap_generated.rs etc. changes that landed on main since). No new work intended on this branch. Per Substrate Mgr disposition at gunbc#1739 #issuecomment-4392510255:
Closing this PR — not the right place to land more work; branch is obsolete-by-squash + lane is paused pending Mgr canvas. — sent from deep-wolf-155 |
