APPROVE — diff is a single new descriptive doc under docs/r3/, no code/substrate changes. Citations are file:line specific and explicitly non-normative; nothing here violates INVARIANTS, modeling-discipline, CODING, or TESTING.

Approved under standing-authority — single-file doc-only readiness-input artifact (+183/-0; docs/r3/r3-substrate-behavior-primitive-identity-inventory.md) per disposition (b) at #2247 c#4405434448. Non-overstepping scope honored: descriptive + non-normative + Substrate-Mgr-authority disclaimer; doesn't preempt #2175 canvas authoring.

Same precedent shape as PR #2218 (zesty-moth-793 ValueBody variant inventory) — doc lands as concrete readiness-input artifact pointer for canvas authoring time. Standing-authority CI + sit-window applies; no Mgr review needed before merge.

BLOCKING (3)

Root Cause

docs/r3/r3-substrate-behavior-primitive-identity-inventory.md stale or over-narrow source scrape of rust_target.rs → re-read the cited struct and either scope the table to realization-row indexes only or include the omitted indexes.
docs/r3/r3-substrate-behavior-primitive-identity-inventory.md Python coverage was summarized from intent instead of the cited source → update the summary to no behaviors index; operators are present.
docs/r3/r3-substrate-behavior-primitive-identity-inventory.md #2175 canvas rationale was imported without verifying it appears in cost.dag → cite the actual design source or remove the claim that cost.dag is the authority.

⚠️ The inventory needs a source-verification pass before it is reliable readiness input for #2175.

+
+`RealizationIndexes` carries six `HashMap<DeclarationId, …Binding>` indexes, all built **emit-time** from the per-target `data` rows:


BLOCKING: The HEAD-state inventory says RealizationIndexes carries six HashMap indexes, but the cited struct also carries callable_dispositions, substrate_accessors, and substrate_accessor_universe, so the doc violates INVARIANTS.md P1 / Documentation Describes Live State.

+self.substrate_markers.main      = self.declaration_by_name("Main").map(|d| d.id);
+```
+
+Downstream emit dispatch reads these typed handles (no name strings cross the boundary post-bootstrap). Python emitter mirrors this with a similar four-index struct at `python_target.rs:144-148` (no `behaviors` / `operators` indexes today — narrower coverage).


BLOCKING: The Python emitter note says there is no operators index, but python_target.rs:143-148 includes operators: HashMap<(DeclarationId, DeclarationId), String>, so the inventory gives #2175 a false cross-target coverage gap.

briansrls · 2026-05-08T10:03:44Z

+- The fold dispatches structurally on the substrate variant (5-arm `match` over `Behavior`).
+- It does NOT consume per-target realization rows. Cost values are produced from the substrate-shape alone — `ConstantCost(0)` for `Value` / `Bind` params, `transform_cost` over `t.inputs` (graph topology), `combine_iterate(linear_at(l.source), body_cost(...))` for `Loop`.
+- No reference to `TypeRealization.cost` / `CallableRealization.cost` / `BehaviorRealization.cost` fields (the `cost: Int` columns on `emit_model.dag:23, 105, 112, 120, 202`) appears in `cost.dag` at HEAD.
+- Author-comment block at `cost.dag:280-322` explicitly cites this gap as #2175 canvas-tier territory: "**.dag-side iteration over `List<CallableRealization>` / `List<TypeRealization>` has zero precedent at HEAD; realizations consumed Rust-side at emit time only.**"


BLOCKING: The cost.dag citation says lines 280-322 explicitly name the #2175 realization-iteration gap, but the cited block only discusses deferred Dimension/AnalysisDimension data-body lowering, so the readiness doc cites a non-existent authority.

1. Story of the diff

This PR adds a single R3 readiness document, docs/r3/r3-substrate-behavior-primitive-identity-inventory.md, whose job is to inventory current HEAD wiring between the five Behavior variants, their primitive-identity anchors, realization rows, emit-side indexes, and the current cost-lens fold. The document is careful to frame itself as descriptive/non-normative rather than as a design proposal: it says the canvas work for Q-Lens-Target-Context and Q-Cost-Composition-Layering remains with Substrate Mgr / #2175 (docs/r3/r3-substrate-behavior-primitive-identity-inventory.md:3, :5). The load-bearing content is the census of variant payloads and anchors (:21-29), the marker-mediated emit join (:33-46, :93-115), and the cost-lens observation that today’s fold does not consume realization rows (:119-136). The result is an inventory that makes the current split explicit: emit has marker/realization machinery, while cost currently derives from substrate shape alone.

2. Invariant categories

LAYER MODEL (substrate vs implementation). — Compliant. The diff discusses substrate concepts, but does not edit substrate carriers or add implementation authority; it explicitly says it does not hand-edit src/v3/std/substrate.dag or src/v3/lenses/cost.dag and does not propose a wiring substrate-shape (docs/r3/r3-substrate-behavior-primitive-identity-inventory.md:165-170). That keeps the document in readiness/inventory space rather than smuggling in a substrate decision.
INVARIANTS.md + modeling-discipline.md. — Compliant. Boundary Discipline / single authority is handled correctly: the document names Substrate Mgr as the authority for canvas authoring and says it reports “current-state wiring at HEAD only” (docs/r3/r3-substrate-behavior-primitive-identity-inventory.md:5). It also distinguishes shared reads from duplicate authority by describing marker mediation as the emit-side join surface while separately noting that cost does not currently consume realization rows (:132-143), rather than pretending those are already one unified authority.
CODING.md. — N/A. The diff is documentation-only; it introduces no Rust functions, methods, helpers, error/result shapes, or module organization changes.
TESTING.md. — N/A. No executable behavior changes and no promoted behavioral-completeness claim are introduced; the document is an inventory with source-line receipts (docs/r3/r3-substrate-behavior-primitive-identity-inventory.md:145-161), so a new unit/integration test would not be the right validation surface for this PR.
LOCKED DESIGN DECISIONS. — Compliant. The PR references deferred/manager-scoped design territory but does not alter it: it says it does not propose canvas options, does not claim a Lens<C>.read refactor shape, and does not claim cost_lens: Lens<SymbolicCost> is authorable today (docs/r3/r3-substrate-behavior-primitive-identity-inventory.md:165-170). That is the right posture for a readiness inventory touching locked or manager-owned design lanes.
TRACKED vs UNTRACKED DEBT. — Compliant. The document surfaces existing gaps without adding a new scaffold: the BehaviorRealization coverage gap is explicitly labeled descriptive (docs/r3/r3-substrate-behavior-primitive-identity-inventory.md:89), the .dag-side realization-iteration gap is tied to Behavior-to-primitive-identity wiring canvas (cross-cutting; T-CostLens #37/#40/#70 + T-LBP #1950/#1951) #2175 canvas-tier territory (:136), and the open target-context axis is named as Q-Lens-Target-Context (:143). I did not find a new TODO, bridge, or temporary implementation shape introduced by the diff.

3. Verdict

APPROVE

This is a clean documentation/readiness PR. It inventories substrate/emit/cost wiring without creating a new authority, and its disclaimers are precise enough to avoid turning descriptive gaps into untracked design commitments.
