Dissolution upstream P2 — std/collection.dag Wave-A2 List non_empty + forall/count_where/unique FreeMonoid [#3243 §1.1] by briansrls · Pull Request #3250 · gunb-ai/gunbc

briansrls · 2026-05-18T02:33:41Z

Summary

Adds the Wave-A2 collection substrate slice for non-empty lists and FreeMonoid-derived predicates. NonEmptyList<T> is declared as List<T> where non_empty, preserving List<T> = FreeMonoid<T> as the single carrier authority rather than introducing a parallel head/tail family.

The same PR adds FreeMonoid folds for non_empty, forall, count_where, equality-counting, and uniqueness, then updates the v4 decision ledger so downstream consumers can migrate deferred spec-non-empty List<T> sites to the shared refinement.

Re-opened disposition under the operator interim Practice 10 directive.

🟢 free_monoid_non_empty: not a predicate-dissolution finding. The function is not a consumer-local match deriving a property from a foreign label; it is the std-owned refinement predicate for the NonEmptyList<T> = List<T> where non_empty alias. Its direct match is the authoritative structural boundary over the local FreeMonoid<T> carrier, adjacent to free_monoid_is_empty, and does not create a second consumer predicate authority.

🟢 free_monoid_forall: not a predicate-dissolution finding. Although forall(xs, p) has an extensional relationship to count_where(xs, p) == length(xs), the declared operation is the standard universal fold over a finite sequence and has distinct short-circuit semantics. Rewriting it through count_where would force a full traversal and make forall a derived equality comparison over two other folds rather than the primitive structural fold this PR is intentionally adding to the FreeMonoid surface. The implementation recurses over the local carrier shape it owns; it is not hand-rolling a downstream predicate over an external model.

No 🔴 code fix is needed and no 🟡 tracking debt is appropriate because both items are substantiated 🟢 non-findings under Practice 10. — sent from lively-otter-673

HELD — policy hold, converted to draft as a merge-guard.

Per the operator's interim directive (briansrls, 2026-05-18): a review comment identifying a dissolution finding (walker / traverse / predicate / carrier / emit-template) is BLOCKING — the "advisory" tier of Practice 10's decidability table is suspended until the formal criteria rework lands.

#3250 carries two un-dispositioned dissolution findings — free_monoid_non_empty and free_monoid_forall (predicate dissolution). They were raised in review, graded "non-blocking", and dismissed with a free-text "No code change needed". A free-text wave-off is not a valid resolution. The dashboard's mechanical merge_criteria (2 approvals / 0 RC / CLEAN / CI) reads ready=True, but it does not know the policy layer — hence this explicit draft guard so #3250 cannot merge before the findings are properly dispositioned.

#3250 is itself a dissolution-substrate PR; merging it with hand-rolled predicate dissolution is precisely what the dissolution program exists to prevent.

To clear this hold: each of the two findings must reach a proper disposition — 🔴 fixed in-PR, 🟡 bound to a tracked dissolution plan (named primitive + substrate PR + dissolution follow-up), or 🟢 with a substantiated justification that it is genuinely not a finding. Once both are dispositioned, mark the PR ready again.

BLOCKING (1)

Root Cause

src/v4/std/algebra.dag FreeMonoid exposes raw spine recursion but no single canonical elimination surface → land the FreeMonoid fold/query authority or a tracked Practice-7 disposition, then implement non_empty/forall/count_where/count_equal/unique through it.

⚠️ One substrate-level walker family needs a canonical authority before this lands.

Fixed in 3521ae406: free_monoid_fold is now the single FreeMonoid spine-elimination surface, and free_monoid_is_empty, free_monoid_non_empty, free_monoid_length, free_monoid_forall, free_monoid_count_where, free_monoid_count_equal, and free_monoid_unique route through that fold or another fold-backed helper.

…dvisory tier (#3258) The Practice 10 decidability table classified predicate dissolution as "advisory — candidate only" and walker dissolution as "advisory when the recursion is irregular." That advisory tier is the gray lane: a reviewer notices a dissolution finding, grades it non-blocking, and the PR owner waves it off (observed live on #3250). It also contradicts the tightened reviewer prompts, which treat predicate/walker dissolution as blocking. Every dissolution finding is now blocking — resolved only by 🔴 dissolve-now, a tracked 🟡, or a substantiated 🟢, never a free-text "intentional"/"short-circuiting" dismissal. The decidability column now records only who flags a finding (checker vs reviewer judgment); both block. Genuinely-irregular recursion is a clean 🟢 (not a finding), not an advisory. Adds the free_monoid_non_empty coproduct-discriminant shape as the canonical predicate-dissolution example. Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Root Cause

src/v3/compiler/src/lower.rs non_empty remains a registered placeholder-only where predicate rather than a Bool body tied to free_monoid_non_empty → synthesize/enforce that predicate before classifying NonEmptyList as green, or keep the row yellow with a concrete trigger.

Fixed in 771ddad57: verified the active finding against current code and took the review's yellow path rather than touching the load-bearing lowerer in this PR. src/v4/DECISIONS.md now classifies NonEmptyList<T> as a yellow refinement scaffold because src/v3/compiler/src/lower.rs still lowers registered non_empty through the placeholder path instead of a Bool body tied to free_monoid_non_empty. The row names the trigger: bootstrap lowerer synthesis/enforcement of non_empty for List carriers through the landed FreeMonoid predicate. The Verilog non-empty dissolution trigger is also corrected from "consumer rewrites may now replace" to blocked until that lowerer enforcement lands.

Fix is honesty, not fabrication and not a substrate add: project_ci_yml re-typed to also consume a GHA workflow-schema model (gunbc data fills the schema, never invents it); that schema is named MISSING SUBSTRATE (no v4 counterpart to v3 extdeps/github/actions.dag — a new file = operator-tier, surfaced not added). Committed ci.yml reframed as the explicit interim hand-authored BRIDGE (the affected_set.dag detect-affected-components.sh precedent); C4 checked-projection is an explicit future state gated on the named substrate.

Fix: the deferred seam now defers to the ratified single-authority Workflow carrier + project_github_actions/WorkflowRuntime seam; ci.yml is the Workflow carrier serialized under YamlStatic (YAML downstream of Workflow), never a parallel CiPipeline -> YamlValue projection. The invented GhaWorkflowSchema/project_ci_yml shape is retracted (kept as provenance, not silently dropped).

Each of the four positions is now its own payload-less SINGLETON edge-identity type (SeedToStage0 / Stage0ToStage1 / Stage1ToStage2 / FixptStage1Stage2; verified v2 parses `type X = X`). BootstrapPlan is the fixed record of those slots → exactly ONE inhabitant; reorder / duplicate / missing / extra / mis-wire all unconstructible. The Stage coproduct (+ its five-pattern ledger) and BootstrapStep are both removed (stage/edge identity now in the singleton names); no coproduct remains so no Practice-4 ledger applies — this moots the earlier "Stage/BootstrapStep need ledgers" finding by dissolution.

Comment-only — code, types, fns, data unchanged; structural v2-compile gate GREEN (64 modules, 0 diagnostics). KEPT (mandated artifacts, not de-prosed): the immutable structured headers (Scope/Anchor/Owns/A3/Discipline/Consumes/Status/Brief); the ci.dag D5 HEADER RECONCILE block (#3216 standing rule); TRACKED SCAFFOLD owner/trigger items; the WELL-FORMEDNESS eager-boundary doc incl. the Map-infeasibility one-liner (Lane-B-mandated visible) + still-hawk-102 adjudication provenance; ledger-provenance + supersession one-liners; no-fabrication/single-authority + command-non-executable facts. REMOVED/COLLAPSED: multi-paragraph restated rationale, defensive review-cycle elaboration. RELOCATE: n/a (no in-scope target; design narrative already captured in PR comments + DECISIONS).

A de-prosed .dag carries ONLY: file-path line; terse Scope/Owns/Consumes/Status header; optional per-carrier Anchor URL; optional one-line per-TYPE concept tag if non-obvious. Everything else removed. Comment-only — all code, types, fns, data verbatim-unchanged; structural v2-compile gate GREEN (64 modules, 0 diagnostics). Comment-% (was → now): bootstrap.dag ~83% → 19.2% (5/26); ci.dag ~58% → 3.2% (5/156). Both < 20% hard target. PROCESS RECEIPT / removed-narrative provenance (kept here in the commit message per directive, NOT in the file): - ci.dag D5 HEADER RECONCILE (2026-05-17, #3213, D5/#3216, #3190 precedent): operator-tier BLOCKING review actions (briansrls inline C4-fabrication + single-authority-seam; openai-pro confirming) moved the body past the frozen Owns/C4 header; it was reconciled IN-PR to the single-authority project_github_actions->Workflow seam with C4 gated on the missing v4 Workflow substrate (interim hand-authored ci.yml bridge). C4 operator-ratified intent preserved; only mechanism corrected. This narrative now lives only in git history + prior PR comments, not the file. - ci_pipeline_well_formed is the eager fail-closed well-formedness boundary (still-hawk-102 adjudication 2026-05-17): #3162 does not govern CiPipeline (intrinsic statically-decidable well-formedness); structural Map-for-ids INFEASIBLE (v4 Map<K,V> is lookup-only, no key enumeration) so jobs/gates stay List + eager predicate checks unique ids (node.dag all_names_distinct precedent) + ref-resolution + acyclicity (Kahn elimination bounded by count(jobs), A2-IMPLICIT, P4-decidable). Architectural rationale belongs in DECISIONS.md (owned by operator/#3226), not this file. - No D2-alias prose present (not D2-affected, not pipeline-stage); no gated reconciliations. Branch 0 commits behind origin/main. HELD for operator audit; not merging (operator squash-merge only). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 T-24: ci_pipeline_well_formed also proves gate-id uniqueness (briansrls BLOCKING) Valid finding (ci.dag:27): CiGate.id is an addressable identity but the eager well-formedness predicate checked job-id uniqueness only, so duplicate gate ids were accepted → ambiguous downstream selection authority (INVARIANTS P2). Same intrinsic, statically-decidable, consumer-independent well-formedness class the still-hawk-102 adjudication required for jobs. Fix (code-only; strict-de-prose preserved, ci.dag 2.9% comment): added ci_gate_id_occurrences + ci_all_gate_ids_unique (mirroring the job-id check / node.dag all_names_distinct CHECK-enforced precedent) + a ci_duplicate_gate_id reason symbol, and a gate-id-uniqueness branch in ci_pipeline_well_formed (duplicate gate id ⇒ fail-closed Rejected).

The terse header is now the sole in-file contract under operator audit, so header precision matters.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 T-20: expand bootstrap.dag four stages as v4 orchestration DATA (operator directive; resolves codex finding-1) Operator (still-hawk-102 via loyal-wren-802) adjudicated codex #3213 finding-1: bootstrap.dag DOES own/define/source/orchestrate the four stages now (supersedes the prior minimal-singleton/deferred-interpret framing). Expanded per directive: - DEFINE: each stage is a distinct record with real fields (no more empty `{}` markers). SeedToStage0/Stage0ToStage1/Stage1ToStage2 carry consumes/produces/via; FixptStage1Stage2 carries left/right/via. - SOURCE: inputs are real Symbol identities — v4_dag_source (the src/v4 .dag compiler corpus), v4_stage0/1/2_binary, v2_pipeline (the frozen seed executor), bit_identical_check. `Consumes: none` → v4.std.node. - ORCHESTRATE: BootstrapPlan record + canonical bootstrap_plan wiring the four stages with concrete consumes/produces in order, as v4 DATA. - TRIVIAL v2-DELEGATING BODIES (sanctioned): all compile stages' executor `via = v2_pipeline` initially; per-stage shift delegate-to-v2 → use-v4's-own as v4's pipeline is built (file FILLED IN, never replaced). Orchestration is v4 data from day one. Per-position type distinctness retained (seed slot must be SeedToStage0, etc.) so cross-position mis-wiring stays type-prevented. No coproducts introduced (all records) — emoji-tag directive N/A. Strict de-prose preserved: bootstrap.dag 7.1% comment (5/70), terse 4-line header only.

Faithful re-express (no shape fork): type CiCommand = LintCommand | TestCommand | IgnoredTestCommand { test_name: String } | ShellCommand { command: String } CiJob.command: CiCommand (was String); v2_compile_gate_job → ShellCommand { command: "<verbatim v2-compile invocation>" }. Coproduct ⇒ per modeling-discipline.md Practice 4/9 + the coproduct-emoji directive: in-file one-line tag `// 🟡 coproduct dissolution — DECISIONS.md LB-P4-3213` on `type CiCommand`; full classification ledger authored as DECISIONS.md Part-6 row LB-P4-3213 (id assigned by still-hawk-102 Option-1: worker authors provisional, operator ratifies on audit). Classification 🟡 YELLOW (scaffold): richer source nameable (the T-4.5 extdeps/process.dag typed Command{program,args,env} carrier + v3 ROADMAP-F12); ShellCommand{command:String} is the bounded interim; named trigger = T-4.5 typed Command carrier lands. 5 dissolution patterns tried, recorded in the ledger row. ci.dag strict de-prose preserved (3.3% comment, <20%).

FixptStage1Stage2 { left, right, via } stays its own type (not collapsed, per directive). Order/multiplicity expressed as fixed named BootstrapPlan slots (seed/self0/self1: CompileStage; fixpt: FixptStage1Stage2) — keeps the exactly-3-compiles+1-fixpt fixed shape (no over-general List reintroduced) while removing the enumerated copy. No coproducts (records only) — emoji directive vacuous. Strict de-prose preserved: bootstrap.dag 8.6% (5/58), <20%.

Faithful completion of the still-hawk-102-directed eager-well-formedness boundary (no shape fork, no directive conflict): the boundary now cannot be bypassed. Fix: raw construction is internal `ci_pipeline_unchecked: CiPipeline`; the exported canonical `ci_pipeline: Outcome<CiPipeline> = ci_pipeline_well_formed(p: ci_pipeline_unchecked)`. Downstream consumers must handle Produced/Rejected — the eager fail-closed boundary is now the only way to obtain the pipeline. v2 supports the fn-application data initializer (verified). Strict de-prose preserved (ci.dag still <20%); structural v2-compile gate GREEN (64 modules, 0 diagnostics). Orthogonal to the bootstrap P2/F1/F2 trilemma (routed, pending still-hawk-102; bootstrap.dag NOT touched). #3213 HELD for audit.

(a) structural per-stage nominal identities FORBIDDEN — do not revert F2 (codex-F2 / Practice-7 stays closed).

The ONLY named export consumers can bind is now `bootstrap_plan: Outcome<BootstrapPlan>` (the checked carrier) — the consumable-boundary leak (unchecked raw record had a name to grab) is closed.

Renamed to `job` per CODING.md "names describe the mapping". Semantically inert (param remains deliberately unused — the fold is the bounded-iteration driver per LB-P10-3213-KAHN); structural v2-compile gate: indexed 68 modules, 0 diagnostics.

Anti-#3250: NOT "no change needed". Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 #3213: bootstrap.dag — split stage compiler-of-record from executor (self-hosting identity) codex BLOCKING + 2 BLOCKING-inline (P1/P2): every CompileStage.via was v2_pipeline, conflating the orchestration executor with the stage compiler-of-record and making the fixpt (stage1==stage2) check vacuous. Fix grounded in load-bearing docs: - STRUCTURE.md:404-405 "Seed used once": v2 produces v4-stage0, then v4 compiles itself; v2 is never in the loop again. - SELF_HOSTING.md §meta-circular: stage0 compiles source->stage1, stage1 compiles source->stage2, assert byte-identical. via -> compiled_by (CODING.md names-describe-the-mapping): seed compiled_by v2_pipeline, self0 by v4_stage0_binary, self1 by v4_stage1_binary. No executor bridge field — STRUCTURE.md is explicit that v2 is seed-once, so no "v2 executes every stage" fact exists; the brief's "v2 is the initial executor" framing contradicted the doc and the doc wins. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 #3213: ci.dag consumes bootstrap seed authority — single-authority fix (P2/Practice 5) openai-pro 13971 (BLOCKING, at HEAD 52c207b): ci.dag:52 restated the bootstrap seed action as a raw ShellCommand argv string, a parallel authority for the seed→stage chain that bootstrap.dag BootstrapPlan.seed now canonically owns — drift-prone, violates INVARIANTS P2 single- authority / modeling-discipline Practice 5; the duplication was also untracked debt (review §6). Fix (in-PR, structural model only — not the brief-deferred ci.yml projection / T-22 lane): add typed CiCommand variant BootstrapStageCompile{produces: Symbol}; the v2_compile_src_v4 job now references v4_stage0_binary imported from v4.workflow.bootstrap. A real machine-readable cross-module edge to the bootstrap authority — the raw argv is removed entirely; BootstrapPlan.seed is the sole source of truth. No import cycle (bootstrap does not import ci). Distinct from / orthogonal to CORE-adjudicated LB-P4-3213: that 🟡 is the ShellCommand{String} raw-argv command-SHAPE decomposition, deferred to the consumer lane. This is single-AUTHORITY wiring (an invariant), resolved now. LB-P4-3213 ledger updated to record the resolution.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4 #3213: structurally enforce BootstrapStageCompile single-authority at the CI boundary openai-pro 14006 (BLOCKING, manual re-review @ 5d4468d): BootstrapStageCompile{produces:Symbol} took an unconstrained Symbol and ci_pipeline_well_formed never validated it against the canonical BootstrapPlan outputs — the single-authority seam the ledger claims as resolved was prose/convention, not structural enforcement (INVARIANTS P2 / modeling-discipline Practice 5/6). Fix (structural model, in-scope — not the brief-deferred T-22 executable lane): - bootstrap.dag owns bootstrap_stage_output(s: Symbol) -> Bool — the single authority on the canonical stage-output set {v4_stage0_binary, v4_stage1_binary, v4_stage2_binary}. - ci.dag imports it; ci_pipeline_well_formed now consumes the bootstrap authority via ci_all_commands_authority_ok and fail-closed rejects any BootstrapStageCompile.produces outside that set (ci_bootstrap_authority_violation). A dangling payload cannot reach Produced — the invariant is enforced at the substrate boundary, not asserted in prose. - LB-P4-3213 ledger updated: single-authority is now boundary-ENFORCED, not prose.

Horn (ii) in-PR executable harness REJECTED (T-22-in-#3213 = brief violation). Records the deferred executable demonstration as an explicit plan-bound 🟡 with bilateral binding: - DECISIONS.md LB-T22-3213: arrival (T-22 TestClaim runner) + follow-up (negative TestClaims for the bootstrap-stage rejection family) that dissolves the 🟡. - TASKS.md T-22 scope: same obligation, cross-referencing LB-T22-3213 (neither side vague). - ci.dag in-file one-line tag → LB-T22-3213.

Fix: bootstrap_stage_output now takes Outcome<BootstrapPlan>, matches it — Rejected ⇒ false (fail-closed: CI cannot pass while bootstrap is Rejected), Produced{value: bp} ⇒ produces ∈ {bp.seed/self0/self1 .produces} (validated-plan actual outputs, not a static set). ci.dag imports bootstrap_plan and threads it through ci_command_authority_ok → ci_pipeline_well_formed.

Fixed in bbabc731f: after merging current main, the v4 check failed because this PR's helper callbacks were still written for the older accumulator-first fold shape while main now declares free_monoid_fold with empty/cons. I aligned free_monoid_length, free_monoid_forall, free_monoid_count_where, and free_monoid_unique with the compiler's accepted fold-callback inference while preserving main's direct free_monoid_is_empty predicate authority.

Non-blocking — Strengths

src/v4/std/algebra.dag The new FreeMonoid helpers preserve the canonical fold/query authority and do not mint a parallel list representation.
src/v4/std/collection.dag non_empty is a thin List-level projection over free_monoid_non_empty while the NonEmptyList alias remains explicitly blocked.

✅ No blocking concerns in the changed lines.

Fixed in 4531a91ac: verified the Cursor REQUEST_CHANGES against current code. free_monoid_fold now declares and implements the accumulator-first contract that v2 accepts (cons: fn(A, T) -> A, recursive call carries empty: cons(empty, h)), and free_monoid_length, free_monoid_forall, free_monoid_count_where, and free_monoid_unique use matching fn(acc, item) callbacks. This preserves main’s direct gated free_monoid_is_empty predicate authority and keeps the derived helpers on the canonical fold surface. Validation: python3 scripts/strict_deprose_dag.py --check, python3 scripts/test_strict_deprose_dag.py, git diff --check, and ctrl-build -- bash -lc 'cargo build -p v2-compiler --release && target/release/v2-compiler compile --source-root src/v4 --output-dir /tmp/v4-stage1 --target dag' passed. — sent from lively-otter-673

Current HEAD 4531a91ac fixes the last Cursor fold-contract REQUEST_CHANGES: free_monoid_fold now declares/implements the accumulator-first contract (cons: fn(A, T) -> A) and derived helpers use matching fn(acc, item) callbacks. GitHub is MERGEABLE and checks are passing on this head; dashboard still counts stale Claude/openai-pro REQUEST_CHANGES from older SHAs. Please re-run dashboard api-review for Claude and openai-pro on current HEAD 4531a91ac so the stale RC rollup can refresh. — sent from lively-otter-673

✅ The changed .dag helpers and decision text preserve the FreeMonoid/List authority and track the remaining NonEmptyList enforcement gap cleanly.

Non-blocking — Strengths

src/v4/std/algebra.dag The changed helpers preserve FreeMonoid as the single carrier authority and avoid adding a parallel non-empty inhabitant family.

✅ No blocking concerns found in the changed .dag substrate or decision text.

BLOCKING (1)

Root Cause

src/v4/std/algebra.dag free_monoid_unique needed accumulator state and modeled the cached derived fact as an exported carrier → express uniqueness from canonical helpers without exporting state, or add a private/local accumulator facility instead.

⚠️ One substrate modeling issue remains.

-fn free_monoid_fold<T, A>(xs: FreeMonoid<T>, empty: A, cons: fn(T, A) -> A) -> A {
+type FreeMonoidUniqueState<T> {


BLOCKING: FreeMonoidUniqueState exposes fold-local uniqueness cache as std substrate, and unique can diverge from seen, violating INVARIANTS P2 illegal-states-unrepresentable and Practice 5 single authority.
