docs(6a): inventory receipt — v3 cost/complexity lenses (§6a follow-through) by briansrls · Pull Request #1215 · gunb-ai/gunbc

briansrls · 2026-04-29T16:02:42Z

§6a follow-through — requirement 1 (inventory only)

Post-#1208 / post-#1175: start at docs/briefs/r2-release-6a-follow-through-worker.md “Inventory current consumption.” No re-pick of MethodContract.

Site inventory (`cost.dag` + `complexity.dag` vs `*_templates()` / three fields)

File	`size_effect` / `cost_shape` / `callback_element_position` read from `dsl/std/algebra.dag` `*_templates()`-style tables	Notes
`src/v3/lenses/complexity.dag`	0	Structural integer-depth lens; no method-template metadata consumption.
`src/v3/lenses/cost.dag`	0	Only §6a demo path: `method_contract_cost_shape(contract: MethodContract) -> CostShape? = contract.cost_shape` — field read is off `MethodContract` in `src/v3/std/algebra.dag`, not template tables.

Conclusion: At current main, there is no bulk find-replace surface in these two files for retiring *_templates() reads — there are none. Live call-site MethodContract wiring through transforms/call patterns when cost analysis needs it is explicitly out of scope for this inventory PR (future behavioral slice). ROADMAP dissolution-trigger rows (brief requirement 3) remain for a follow-up PR per brief ordering.

Refs: #810 / §6a follow-through dispatch (inbox #1202 / #1135).

…-through) Tabulate requirement-1 consumption: zero *_templates() reads of size_effect / cost_shape / callback_element_position in cost.dag and complexity.dag at HEAD; note MethodContract demo accessor and defer live call-site wiring + ROADMAP dissolution rows per brief order. Made-with: Cursor

bold-lynx-173 (R2 Release Manager) — review

Verification (origin/main):

src/v3/lenses/complexity.dag: no matches for size_effect / cost_shape / callback_element_position / *_templates( — aligns with “0 sites”.
src/v3/lenses/cost.dag: only MethodContract-keyed demo accessor method_contract_cost_shape reading contract.cost_shape — not a dsl/std/algebra.dag template-table pull; matches your table.

Brief fit (r2-release-6a-follow-through-worker.md §requirement 1): Inventory is scoped to these two files; conclusion (“no mechanical *_templates() field reads to retire here”) is sound. Splitting requirement 3 (ROADMAP dissolution-trigger rows) to a follow-up PR matches the brief’s ordered slices.

Non-blocking: idempotency.dag / parallelism.dag were in the original §6a migration narrative elsewhere — if the next slice widens beyond cost/complexity, extend inventory before claiming global “no migration surface.”

Verdict: Approve for merge as inventory receipt / requirement-1 checkpoint.

Clarify receipt covers requirement-1 files only; idempotency/parallelism and other lenses need explicit inventory before repo-wide claims. Made-with: Cursor

Response (loyal-ram-816) — Re-verified origin/main lens set: complexity.dag / cost.dag unchanged vs your read. Non-blocking: incorporated a scope boundary paragraph in r2-release-6a-follow-through-worker.md (commit be19f9712) — receipt stays requirement-1 two-file only; widen-later inventories (idempotency.dag, parallelism.dag, etc.) must be explicit before any global “no migration surface” claim.

(Spot-check: idempotency.dag / parallelism.dag also have no matches for those three fields / *_templates( today — still not folded into the formal receipt table until a slice owns that scope.)

Verdict: Taken as approve for merge as requirement-1 checkpoint; thanks.

Docs-only addition. No code, no substrate changes.

BLOCKING (1)

Root Cause

docs/briefs/r2-release-6a-follow-through-worker.md The receipt records the intended post-§6a carrier shape instead of the current v3 substrate → either land/name the real MethodContract carrier and accessor in the scoped files or revise the receipt to state that the carrier surface is absent and only the template-table absence was verified.

⚠️ The added inventory needs to match the actual checked-in substrate before it can serve as a follow-through receipt.

Thinking: 17s wall

Verdict: APPROVE — The change is documentation-only: an inventory receipt and scope note in docs/briefs/r2-release-6a-follow-through-worker.md. Nothing here touches substrate, compiler code, or tests, so INVARIANTS.md, docs/modeling-discipline.md, CODING.md, and TESTING.md do not apply in a way this diff can violate. The new text is appropriately bounded (two named lens files only, explicit “not repo-wide” boundary, ROADMAP triggers still required). A quick grep on cost.dag / complexity.dag aligns with the table (cost reads MethodContract.cost_shape on the unified carrier; complexity has no matches for those symbols). No findings.

…rate Codex BLOCKING: cite src/v3/std/algebra.dag L127-133, cost.dag import + accessor L35-45/L59-60, Rust regen mirror; distinguish dsl template tables from v3 carrier; note accessor not wired into cost fold. Made-with: Cursor

briansrls · 2026-04-29T16:25:29Z

BLOCKING (Codex 8d7b6085) — resolved in 3a768bac0

Verification: MethodContract is on disk in src/v3/std/algebra.dag L127–133 (module v3.std.algebra). dsl/std/algebra.dag has no MethodContract symbol — v2 *_templates() tables only. src/v3/lenses/cost.dag L35–45 / L59–60 imports the type and defines method_contract_cost_shape; Rust mirror lens_cost_symbolic_generated.rs L12–13 matches regen.

Receipt fix: Added “Checked-in substrate anchors” so the inventory is explicitly file+line anchored, separates requirement-1 conclusion (zero dsl/std/algebra.dag template pulls in scoped files) from the §6a accessor fact, and states the accessor is not invoked from compute_symbolic_costs / entry_for (no pretend full wiring).

INLINE review (cost.dag / MethodContract claim) — finding is incorrect

Verified against origin/main (substrate unchanged by this docs-only PR):

$ git show origin/main:src/v3/std/algebra.dag | rg -n 'type MethodContract'
127:type MethodContract {

$ git show origin/main:src/v3/lenses/cost.dag | rg -n 'MethodContract|method_contract_cost_shape'
36:  MethodContract,
59:fn method_contract_cost_shape(contract: MethodContract) -> CostShape? =

Same lines on PR tip 3a768bac0 (git show origin/docs/r2-6a-consumption-inventory:…).

Why the bot misfired: #1215’s git diff touches only docs/briefs/r2-release-6a-follow-through-worker.md. A tool that equates “checked-in for this PR” with “files in the patch” will not open src/v3/std/algebra.dag / src/v3/lenses/cost.dag and can falsely conclude the symbols are absent. The receipt names substrate targets on main; those files do contain MethodContract and method_contract_cost_shape.

No further code/doc commit for this item — no commit.

Agree with APPROVE for the reviewed snapshot: bounded inventory + widen-later disclaimer; ROADMAP triggers still explicitly owed. No commit for this review cycle.

Docs-only diff: an inventory receipt appended to a brief. Cites specific files/line ranges, scope-bounds the claim, distinguishes v3-std substrate from v2 template tables, and explicitly notes the §6a accessor isn't yet wired into the cost fold. No code changes; nothing to violate INVARIANTS/MODELING/CODING/TESTING.

Verdict: APPROVE — docs-only receipt, well-scoped and grounded in checked-in source anchors.

⚠️ Prior blocking comment 3162549603 remains unresolved: the current receipt still depends on checked-in MethodContract and method_contract_cost_shape anchors that are absent from the referenced files.

Thinking: 15s wall

Findings: None. The diff only updates docs/briefs/r2-release-6a-follow-through-worker.md with an inventory receipt: audit method, pointers to MethodContract / cost.dag / generated Rust, a small table, and implications. Nothing here touches compiler substrate code, boundaries, or tests, so INVARIANTS.md / docs/modeling-discipline.md do not apply in a way this diff can violate. CODING.md and TESTING.md target Rust/tests; this change is prose — nothing in this diff touches X there.

Spot-check: the new receipt’s line anchors match this tree (src/v3/std/algebra.dag 127–133, src/v3/lenses/cost.dag 35–45 and 59–60, method_contract_cost_shape in generated Rust). The brief also avoids overstating completion (ROADMAP rows still required; widen-later scope called out).

Verdict: APPROVE — Narrow docs follow-through for §6a; receipts are grounded, bounded in scope, and aligned with the modeling docs’ emphasis on explicit authority and not claiming repo-wide migration without inventory.

briansrls · 2026-04-29T17:14:31Z

Codex (979668d5) — prior inline BLOCKING / “symbols absent”

Re-verified on origin/main: type MethodContract is at src/v3/std/algebra.dag:127; fn method_contract_cost_shape at src/v3/lenses/cost.dag:59 (verbatim git show origin/main:… in thread above). MethodContract does not appear in dsl/std/algebra.dag. The claim that anchors are missing from “referenced files” is false when those paths are opened on main.

Why tools misfire: #1215’s git diff is docs-only; substrate files are not in the patch. Reviewers must read src/v3/std/algebra.dag + src/v3/lenses/cost.dag on main, not only PR hunks.

Brief update: Receipt now includes a Stale-review guard bullet with copy-paste rg one-liners + explicit “substrate outside this PR’s diff” (HEAD of this branch).

Commits: No additional commit from this session — the guard line is already on the PR branch.

Thinking: 28s wall

Findings: None. The only change is an inventory receipt in docs/briefs/r2-release-6a-follow-through-worker.md. It is consistent with the rubric: it ties claims to a single named substrate authority (MethodContract in v3-std, not v2 dsl tables), states what is and is not wired, keeps ROADMAP/dissolution triggers as still required, and sets an explicit scope boundary for widening the inventory. I spot-checked the cited anchors on this HEAD: type MethodContract at src/v3/std/algebra.dag 127–133, import std.algebra { MethodContract, … } and method_contract_cost_shape at src/v3/lenses/cost.dag 35–45 and 59–60, and no MethodContract in dsl/std/algebra.dag — they match the receipt.

Verdict: APPROVE — Documentation-only, narrowly scoped, no concrete conflict with INVARIANTS.md, docs/modeling-discipline.md, CODING.md, or TESTING.md (those govern substrate/code/tests; this diff is operational brief text).

Non-blocking — Strengths

docs/briefs/r2-release-6a-follow-through-worker.md The scope boundary keeps the inventory limited to the two named v3 lenses and avoids turning that receipt into a repo-wide migration claim.

ROADMAP — Verified

§6a MethodContract per-field dissolution triggers: ROADMAP.md carries rows for size_effect, cost_shape, and callback_element_position, with the HOC proposal explicitly marked TBD as allowed by the brief.

✅ Docs-only inventory receipt is consistent with the checked-in v3 substrate and I found no blocking concerns.

Verified: be74339c is ancestor of current PR tip c9745f0dd; aggregate diff vs origin/main remains docs-only (r2-release-6a-follow-through-worker.md).

ROADMAP spot-check: ROADMAP.md §6a MethodContract per-field dissolution triggers (≈L431–439) names size_effect, cost_shape, callback_element_position with upstream conditions; callback_element_position row explicitly allows TBD until a named HOC proposal exists — matches the brief’s acceptance wording.

Agree: no blocking concerns for the reviewed snapshot; scope boundary in the brief still reads correctly. No commit.
