Compiler pipeline design by briansrls · Pull Request #98 · gunb-ai/gunbc

briansrls · 2026-02-28T18:38:32Z

Implements core Compiler Pipeline Refactor (Worker C) tasks to enhance type safety, enforce fail-closed resolver behavior, and refine task planning.

This PR progresses the Compiler Pipeline Refactor (Worker C lane) by:

Modernizing syntax with first-class PipeMethod and PipeCall to remove brittle allowlists.
Enhancing type safety and reducing runtime errors by introducing a cached StdLibHost and migrating to explicit typed enum values, eliminating string-based fallbacks.
Strengthening resolver reliability by removing implicit passthrough fallbacks and strictly enforcing required outputs (ExecError).
Improving registry generation by prioritizing ServiceTransportClass metadata over heuristic node-id matching.
Updating tasks.md to explicitly capture postmortem-derived fixes (C10a, RT4a/b/c) and critical ordering constraints, including a warning for the inventory linkage trap during C11/C12 crate migrations.

…cture.md §Acceptance Per codex BLOCKING review on PR #2750 (2026-05-12T07:34:59Z): scope doc lines 13 and 84 claim r3-structure.md was "updated in this PR" + reference 103-gate total per r3-structure.md §Acceptance, but the PR only changed r3-program-plan.md — r3-structure.md still had no #98–#103 rows. That violated INVARIANTS.md P2 / modeling-discipline.md Practice 5 (single-authority metadata) — the closure ledger became internally inconsistent at the canonical-source level. Fix: add the 6 NEW gate bullets to r3-structure.md §Acceptance T-Workflow-As-Data section (after `ci_workflow_modeled_as_dag`), mirroring r3-program-plan.md §1.8 rows #98–#103. Each bullet carries the full Pass-condition body (single-source authority for Pass conditions per the r3-program-plan.md convention). Now both docs land the same gate set atomically in this PR: - r3-program-plan.md §1.8 rows #98–#103 (commit ef9a140, prior) - r3-structure.md §Acceptance T-WAD bullets (this commit) — matching content The "Documentation Describes Live State" rule + single-authority discipline restored.

… + scope-doc cross-ref qualifier (codex BLOCKING + non-blocking on PR #2750) Two findings from codex review #10042 on commit 0c08f77 (T-WAD ledger sync PR head): BLOCKING — "T-WAD ledger sync updated the Acceptance archive but skipped the lane-definition gate lists → update those T-Workflow-As-Data gate lists to include #98–#103 or make them pointer-only." The PR #2750 cascade landed the 6 NEW T-WAD FULL gates (#98–#103) in: - r3-structure.md §Acceptance T-Workflow-As-Data bullets (lines 172-177) - r3-program-plan.md §1.8 ledger rows - r3-program-plan.md count propagation (§0/§1.5/§1.6/§1.7/§5.2/§10/§Q1) But the cascade missed two lane-DEFINITION gate lists in r3-structure.md that ALSO enumerate T-WAD closure gates: - Line 41 (numbered lane list, T-WAD entry) - Line 222 (T-WAD row in §"Lane structure" table) Both listed only the original 4 pre-FULL gates (workflow_substrate_carriers_landed / timing_lens_carrier_landed / ci_workflow_modeled_as_dag / shared_external_attachment_pattern_documented). Reviewers reading either list would not see the 6 NEW gates — INVARIANTS P2 single-authority gap. Fix: convert both lane-definition lists to pointer-only references back to §Acceptance T-WAD as the canonical gate list. Rationale: §Acceptance is the authority anchor (per INVARIANTS P2 + sister r3-program-plan.md §1.8); duplication in lane-definition lists would re-introduce drift the cascade is closing. Also augmented both lane-definition entries with FULL R3-close elevation 2026-05-12 framing + multi-Mgr ownership (Substrate Mgr Slices 4-5/8 + Verification Mgr Slice 7 affected-set + Debt-Paydown Mgr Slice 6 sub-component). Non-blocking — "Line 172 cites docs/r3-t-workflow-as-data-full-r3-close-scope.md, but git ls-tree origin/main returned no blob → replace with existing receipt or land the scope doc." The scope doc exists on PR #2744's branch (in flight) but not on origin/main yet. Codex correctly notes the dangling cross-reference against current main. Fix: add explicit "(scope doc landing via in-flight PR #2744)" qualifier so future readers know the citation is forward-referencing a known in-flight PR rather than a typo or missing doc.

The earlier qualifier fix ("scope doc landing via in-flight PR #2744") acknowledged the dangling reference but didn't resolve the structural P2/P5 violation — the gate description still CITED an authority that doesn't exist on origin/main, which is the merge target. Audit: grepped both docs for refs to files that don't exist on origin/main: - docs/r3-structure.md:172 — `docs/r3-t-workflow-as-data-full-r3-close-scope.md` (PR #2744) - docs/r3-program-plan.md:326 — `docs/briefs/r3-t-wad-full-r3-cidag-scaffold-worker.md` (PR #2744) Fix: replace both file-path references with PR-number anchors. PR numbers are stable references; file paths become valid only post-merge. Gate descriptions are self-contained without the cross-references (the (a)/(b)/(c) enumeration + supporting framing already conveys the gate's substance). - r3-structure.md:172: "per `docs/r3-t-workflow-as-data-full-r3-close-scope.md` §1 — scope doc landing via in-flight PR #2744" → "in-flight scope authority at PR #2744 §1" - r3-program-plan.md:326: "WI-2 implementation: `docs/briefs/r3-t-wad-full-r3-cidag-scaffold-worker.md`" → "WI-2 implementation: in-flight via PR #2744 (brief lands with the scope-doc)" Both gates retain full substantive content; only the file-path crutches are removed. When PR #2744 merges and the files exist on main, future authors may re-add file refs cleanly — but the gate descriptions never needed them as load-bearing authority.

PR #2824's prior commit message claimed a header count sweep but the diff only updated SOME of the count sites, leaving 10 lines internally inconsistent. This commit completes the sweep.

Director will cite this file in their forthcoming worker brief (`docs/briefs/r3-ci-layer-2-path-conditional- gating-worker.md`) as the starting template for Verification Mgr (clever-tern-670) inventory finalization. Content: - §1 affected-set lens Dimension enum reference (cite design doc §2) - §2 slow-test inventory grouped into 9 clusters (78 entries from scripts/slow-test-exemptions.txt) - §3 path-mapping skeleton table — (test_pattern, dimension, required_paths_regex, confidence, dissolution_note).

This conflicts with the locked design at `docs/design-affected-set-lens.md` §2: affected_set(Dag_before, Dag_after) = ⋃ over dim in {Value, Cost, Complexity, Effect, Refinement} affected_set(Dag_before, Dag_after, dim) A test that reads BOTH Cost AND Complexity (e.g., D-cluster LBP demonstration; lane2_stage_2f composed-matches-lens) would be silently skipped when only Complexity changes if its dimension is narrowed to "Cost."

A Mgr/worker following the brief literally would have wired the CI gate backward, silently skipping affected tests — TESTING.md "test selection must not skip affected behavior" violation + Boundary Discipline violation (boolean carrier name and contract encoded opposite meanings). **The bug**: 4 places stated post-dissolution `skip_<cluster>` formula as `(affected_dimensions ∩ group.dimensions) ≠ ∅` (skip when intersection NON-empty), while the CI consumer wires `if: skip_<cluster> != 'true'` (run when skip is NOT true). Combined: when intersection is non-empty (= affected), skip=true → tests don't run → affected tests silently skipped. **The fix**: invert the formula to `(intersection = ∅)` (skip when intersection IS empty = no affected dim that this cluster reads). The CI gate semantics stay the same; the polarity correction is on the post-dissolution lens mapping. Sites corrected: - §1 hard-constraint para (line 9): replaced "(non-empty intersection means run)" with an explicit Boolean polarity block defining `skip = (intersection = ∅)` and equivalent `run = (intersection ≠ ∅)` - §3 path-mapping intro (was line 132, now 142): same polarity fix + "Equivalently: `run = (intersection ≠ ∅)`" - §4 open-question 4 (was line 186, now 196): "skip_<cluster> becomes `(intersection ≠ ∅)`" → `(intersection = ∅)` with explicit "same polarity: skip when no affected dim" note - §5 acceptance (was line 206, now 216): same polarity fix + explicit "inverting the polarity silently skips affected tests" warning All 4 references now consistent. Polarity table: intersection = ∅ → skip=true → "do not run" (NOT affected, safe to skip) intersection ≠ ∅ → skip=false → "run" (affected, must run) Director's brief #2719 likely has the same polarity issue and will need parallel fix from the same authority chain.

Mechanism of the bug: - Markdown tables use `|` as column separator - To put a literal `|` IN a cell (outside backticks), you escape with `\|` - PM authored the regex with `\|` thinking the markdown-table escape was needed, but the regex is INSIDE backticks (code span) which preserves pipe character literally - A worker copying the regex into ci.yml would silently miss tokenize.dag changes (only matches literal `compiler|std/tokenize.dag`) Fix: drop the unnecessary `\` escape; markdown code spans preserve `|` literally. Now regex correctly reads `src/v3/(compiler|std)/tokenize.dag` — alternation between src/v3/compiler/tokenize.dag and src/v3/std/tokenize.dag, both of which exist per the source tree verified at 45fc195.

My prior open-enum fix (c61a7ed) updated §1/§5/§6 to ALLOW user- defined dims but I didn't fix THIS row to USE one. Per the just- established 'carry the dim, don't narrow' framing in §6, this row should carry `[Value, Cost, Timing]` (or just `[Value, Timing]` if Cost is sufficiently distinct from Timing in the test). **Why it's load-bearing**: a future timing-only delta (e.g., DimensionReport schema change touching only timing fields, not Cost) would be 'affected' for this test under the lens but the prior row narrowed Timing → Cost → if Cost.affected = empty but Timing.affected non-empty, test would be silently skipped (TESTING.md violation + THESIS user-defined-dims framing violation). Fix: - Row dimensions: `[Value, Cost]` → `[Value, Cost, Timing]` - Row dissolution-note: explicit annotation citing `DimensionReport<TimingMeasurement>` + `ci_modeled_timing` user- defined dim + the carrying-vs-narrowing rationale - Self-references this template's own open-enum support per §1 — the row is now an in-table demonstration of the open-enum framing (consistency between framing and example) This also re-stress-tests cluster aggregation: cluster H aggregates over multiple rows including this Timing-carrying row, so cluster- level skip computation correctly fail-closes when ANY row's dim intersects with affected_dims.

PM-authored planning doc replacing "viz-as-SoT closed_at + DECLARED-strings-are-drift" framing with explicit per-gap disposition for the 10 substantive counterfactuals surfaced by today's adversarial audit: 1. PB-0 zero hand-Rust (177+ entries in EXPECTED_HAND_AUTHORED_NON_TEST; gate #8 DECLARED) 2. L5 cross-target consistency (gate #15 DECLARED; no Python/Go executable emission on main) 3. Self-host fixed point R3-strong (gate #16 R1-horizon only; 4 joint preconditions deferred) 4. Lens behavioral parity (3 of 4 lenses NOT behaviorally complete; gates #79/#81/#82/#83) 5. Tests-as-data completeness (gate #84 Cluster M Phase 3 bulk-port pending; load-bearing-blocking) 6. v2 retirement terminal (gate #97 coherence-only; src/v2/ exists at HEAD) 7. T-WAD FULL R3 (gates #98-#103 all DECLARED; ci.yml still hand-edited) 8. Bootstrap-seed Rust survivors (folded into Gap 1) 9. Show-the-correct-code (no §1.8 gate exists for THESIS:103-105) 10. Close-audit doc absent (interrogation §8 self-check has no execution log on main) For each gap: promise verbatim + HEAD evidence + what's missing + plan to cash (owner, sub-program, effort estimate) + close criterion predicate. §2 dispatch sequencing: 6 phases A-F mapped to Substrate Mgr / Verification Mgr / Debt-Paydown Mgr / Director-tier coordination / PM-direct. §3 total time-to-actual-close: 8-12 weeks optimistic; 12-20 realistic; 6+ months if PB-0 retirement is the longest tail and can't parallelize aggressively. §4 operator decision points: 4 binary IN-R3 / R4-defer choices that determine actual R3 scope (PB-0, L5 cross-target, self-host R3-strong, show-correct-code). §5 process discipline (preventing future drop): single authoritative plan doc, weekly PM closure-cadence message, per-gap closure-PR template, Gap 10 (close-audit doc) authored FIRST as receipt mechanism.

Surfaced as tightening lever, not foreclosed. 4. **Gap 5 close-criterion header-marker filter** — Predicate amended to `xargs grep -L "// AUTO-GENERATED FROM .dag" | wc -l == 0` so generated-from-.dag tests are filterable. Substrate prereq: code-gen emits header line; if not present at HEAD, lands in Gap 5 Phase 3 ratchet. 5. **Gap 6 transitive-dependency depth** — Explicit 5+ deep chain call-out: Gap 6 ← Gap 3 ← {Gap 1, R2-Evaluator, R2-Grounding, Row-B}. Gap 6 framed as close-ceremony terminal gate (last 2 weeks of R3 close). 6. **Gap 9 threshold = operator decision** — ≥80% pragmatic relaxation is operator-decision-shaped, not Director-decision. §4 now surfaces (a) IN-R3 vs not-R3-promised choice + (b) if IN-R3, threshold = 100% (THESIS-correct) or ≥X% pragmatic with named-residual list. Per `project_no_r4_carves_directive`, the not-R3-promised reframe is structurally an R4-carve requiring operator override. 7. **Gap 10 timeline calibrated** — Skeleton 1-2 days (PM-direct, unblocked, immediate); execution 1-2 weeks (Verification Mgr serial) or 3-5 days (ctrl-build parallel). Overall ~1-2 weeks for full landing. 8. **Phase F bookkeeping downstream of close-audit-doc verdict** — §2 Phase F reworded: §1.8 manifest strings sync to close-audit-doc predicate-execution outcome (View-4-authoritative per `feedback_r3_close_three_views_drift`), NOT to procedural `closed_at` markers.

Zero references to "Tier-2", "grounding submodules deferred", or any R4-deferral carve-out mechanism. The "Tier-2 R4-deferred per design-pure-bootstrap-zero.md" citation in Gap 1 alternative-disposition was fabricated authority — an unauthorized escape hatch against the absolute 0-floor target. **Fix**: - Removed the fabricated citation - Explicit statement: PB-0 design doc admits no internal escape hatch - R4-carve of PB-0 subsets requires explicit operator override of project_no_r4_carves_directive (2026-05-08), naming specific subset + structural-unblockable reason — not citation of an unauthorized escape - PM-recommendation preserved (do NOT R4-defer; standing directive applies) Symmetric to the Gap 9 pragmatic-relaxation fix at commit 870f6ce — both findings reflect the same anti-pattern of converting absolute thesis claims into negotiable thresholds via fabricated/imputed authority.

A textual comment is gameable; a developer could add `// AUTO-GENERATED FROM .dag` to a hand-authored file to bypass the ratchet. The THESIS claim ("every Rust test ports to .dag or is generated") is structural and requires a structural predicate. **Fix**: replaced the textual-marker predicate with the structural EXPECTED_HAND_AUTHORED_TEST list-emptied authority — the same ratchet Gap 1 uses for EXPECTED_HAND_AUTHORED_NON_TEST. Every hand-authored test entry must be named on the list (PR-template enforcement); migrations remove entries; close fires when list empties. The list discriminates structurally, not textually. Preserved the no-boundary-carve-out authority citations (separate codex BLOCKING) — boundary entries are named on EXPECTED_HAND_AUTHORED_TEST and dissolve through migration like any other entry, no separate carve-out.

The type itself admits the illegal state; behavioral checks ("did this fired diagnostic produce a correction?") are API-tier enforcement that the carrier-tier should subsume. **Fix**: substrate-shape constraint added to Gap 9 sub-program step 4: canvas authors MUST commit `correction: Witness` (non-optional) — Practice-2 carrier refinement makes diagnostic-without-correction unrepresentable by construction. Anti-pattern symmetric to Gap 9 pragmatic-relaxation fix at 870f6ce (both findings convert absolute THESIS claim into expressible-but-forbidden state).

Codex stronger ask: "remove the example OR require operator-approved amendment to PB-zero authority". Reframed: no Tier-2 example survives this section; any R4-carve requires BOTH (1) override of project_no_r4_carves_directive AND (2) amendment to docs/design-pure-bootstrap-zero.md authority text adding a per-subset deferral carrier. Neither alone is sufficient. **B2 — Generator-manifest positive structural authority** (Gap 5 close criterion): Prior fix at 29684a0 gave negative authority (list-emptied) but codex asks positive form. Added dual predicate: (a) EXPECTED_HAND_AUTHORED_TEST = empty [negative] + (b) generator-manifest maps each surviving test → its .dag source + regeneration-byte-equality fail-close on drift [positive]. Catches orphan generated files that negative form alone misses. Substrate prereq: manifest carrier authored as Cluster M Phase 3 expansion. **B3 — Deferral carrier with named reason** (Gap 9 substrate-shape): Prior fix at 5872dae had correction: Witness covering only the 100% path. Codex asks separation of absolute-thesis vs pragmatic-residual into named carrier variants. Reshaped to sum Correction = LiveCorrection { witness } | DeferredCorrection { reason, retirement_plan }. Diagnostic.correction is mandatory Correction (not Option). Residual is structurally named with retirement-plan accountability; gate #84/#106 close requires every DeferredCorrection ratchetable to zero per its own retirement plan. **NB1 — Ledger-derived row-count** (Gap 10 close criterion): Hard-coded "ALL 105 rows" rotted as soon as Gap 9 proposed row #106.

No threshold negotiation; no sub-decision (b) since §4 removed it. §4 is now the single authority for the Gap 9 disposition. **Finding 2 (exploratory) — §6 vs footer drift**: §6 line 453 marks "Director ratifies this plan structure — APPROVED 2026-05-13" ✓ but footer at line 471 still said "DRAFT pending Director ratification + operator scope approval".

Moved "(ii) R3 Evaluator Mgr lane owner identified" from close criterion to new "Dispatch staffing prereq" section. Close criterion now purely substrate-debt-shaped. Note 3 (sequencing): re-spawn AFTER operator §4 sub-item 5 ratification, NOT before. Sequence explicit in Dispatch staffing prereq section per `feedback_construction_over_ratchets` adjacent class — don't author the Mgr until the operator-decision substrate cashes.

…nterpreter) Per operator audit-pass review 2026-05-15 + operator-raised concerns ("what about affected set lens? ... what about the interpreter"). Cross-checked every §1-§12 questionnaire promise against the v4 file tree + TASKS.md. Verdict: v4 scaffold PASSES the completeness bar — every promise has an owner + task. 4 gaps found and closed in-PR. ## 4 new scaffold files **lens/application.dag** (T-23) — closes prior-audit BLOCKING GAP 1. `apply_lens(<lens>, Enforce {})` was referenced by report.dag / synthesis.dag / the C7 advisory→blocking bridge but had no substrate home. It's simultaneously §1.5 user-defined-dims surface, §6.2 audience-duality opt-in-depth, and the ONLY advisory→fail-closed path. Carriers: EnforcedApplication<Output,Budget> + IntrospectApplication (v3 T-Lens-Application-Surface precedent, r3-structure.md:40). **workflow/ci.dag** (T-24) — closes prior-audit BLOCKING GAP 2. THESIS:223-226: adding a CI gate = editing one .dag file. v3's gate #98 ci_yml_hand_authority_dissolved was open precisely because CI YAML stayed hand-authored. .github/workflows/ci.yml becomes a DERIVED Shape-B artifact; consumes affected_set for job selection. **lens/affected_set.dag** (T-21) — operator-raised, EARLY priority ("something i wanted to get working very early on"). Phase 1.5. Incremental re-exec frontier; the structural authority that replaces scripts/detect-affected-components.sh (the interim shell bridge currently gating v2/v3/v4 CI). THESIS §205-210 free consequences. **compiler/05_eval.dag** (T-22) — operator-raised ("what about the interpreter"). THE PRIMARY execution path per THESIS:225 ("dag run is the primary execution path"). Sibling of 05_emit.dag — same InferredTree input; eval EXECUTES, emit PROJECTS. bootstrap.dag + TestClaim eval + lens dry-run all compose over it. XL scope. ## Audit doc — §0.5 AUTHORITATIVE status section Added consolidated v4-scaffold-completeness status section after §0. Single source of truth: the 4 gap closures (table with owner+task), §3.7d dry-run = NOT-PROMISED-as-separate-file (emergent from eval + lens), §6.2 fixtures covered by T-14/T-16. Supersedes scattered stale R4-DEFERRED/SCAFFOLD-GAP wording in §1-§17 (consolidated truth instead of line-by-line hunt — same anti-drift discipline as the task-count fix). Verdict recorded: PASSES; remaining work is implementation under complete substrate allocation, not missing structure. ## STRUCTURE.md / TASKS.md - lens/ 9→11, compiler/ 7→8 (05_eval), workflow/ 6→7 (ci) - Counts: 53→57 .dag; 61→65 total - 24→28 XL tasks; T-21/T-24 in Phase 1.5, T-22 in Phase 2, T-23 in Phase 3; execution graph + 4 task defs added - Consistency verified: 28 task defs = "28 XL tasks"; 57 .dag files; all T-IDs present T-1..T-24 + T-4.5-4.8 ## Bootstrap viability v2 indexes 57 modules, 0 diagnostics. fmt clean.

* v4: structural scaffold + 15 XL task plan Synthesis of v2 (1-residual proven self-host) + v3 (modeling depth + substrate refinement) with the structural fix to v3's hierarchy/gaming failure mode applied from day 1: work-direction modeled in .dag (workflow/*) so briefs cite typed DocAnchors and worker outputs declare which substrate fact dissolves which residual. This commit is a structural commitment, not implementation. 28 .dag files are scaffolded with header-only content declaring scope, owned substrate, consumed substrate, and the task that fills them in. Three docs encode the closed-system invariants: - STRUCTURE.md: enumerated file tree (closed system, no new files without operator ratification) - BRIEF_TEMPLATE.md: worker brief shape (immutable across tasks; encodes the structural fix to v3's prose-translation drift) - TASKS.md: 15 XL tasks defining "v4 done" with execution graph File tree highlights: - std/* (8): substrate primitives — node, algebra, cardinality, witness, diagnostic, primitive, collection, verification (TestClaim schema imported from v3) - extdeps/languages/* (3): Rust/Python/Go target specs - compiler/* (6): pipeline stages 01_tokenize through 05_emit (v2's proven naming; 04_infer kept as ONE file vs v2's 12-file split, with split = substrate-design escalation) - lens/* (6): complexity, cost, parallelism, effect, ownership, idempotency - workflow/* (5): brief, worker_output, doc_anchor, retirement, cycle — recursive-flex substrate, IMPLEMENTED FIRST so subsequent worker outputs are typed instances from day 1 - bin/main.dag: emits main.rs trampoline (0-floor compliant) Bootstrap chain: v2's compiled binary is stage minus one. v4 .dag is written in v2-syntax-compatible subset until v4 self-compiles. New syntax additions land only after self-host fixed point. The closed-system invariants make v3's failure modes structurally impossible at v4 worker tier: paper-shrink V1 (template-relocation) requires adding files (forbidden); paper-shrink V2 (module-relocation) requires reaching outside declared substrate (forbidden); ratchet gaming requires the "retirement" predicate to be list-length (it's a structural Witness check via workflow/retirement.dag). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: add pipeline orchestrator + ratify substrate decisions from PR review Per operator review of PR #3147 v4 scaffold against THESIS coverage: ## Added file - compiler/00_compile.dag — pipeline orchestrator (Source, TargetSpec) -> Result<TargetSource, Diagnostic>. Wires tokenize → parse → normalize → resolve → infer → emit. Mirrors v2's compile.dag pattern. Without this file there was no v4 home for the top-level compile() function — bin/main.dag (trampoline) needs something to call. Bundled with T-10 (emit) since the orchestrator is consumer of every prior stage. ## Architectural commitments (new STRUCTURE.md section) Three substrate-level decisions ratified during review, captured in STRUCTURE.md so per-task briefs can reference them: 1. TypeNode and Behavior are CLOSED enums (C1 stop-signal, THESIS:202). Substrate extension requires explicit operator ratification. Closure enforced in std/node.dag itself, not by review process — the compiler reads the closed enum and refuses programs that synthesize outside it. 2. Tier 2 partial-op totalization lives in std/primitive.dag (THESIS:175-176). Each primitive declares its partial ops' totalization shape (Result-return / Witness-return / refinement- precondition) inline, no separate registry. 3. Diagnostic schema includes suggested_correction (THESIS:103-105 "show the correct code"). Schema: Diagnostic { reason, at, suggested_correction: Option<NodeFragment> }. Lenses populate where structurally possible; absent fix is None, not a missing field. ## Updated counts - 28 → 29 .dag files - 31 → 32 total files at scaffold time - compiler/ now has 7 files (orchestrator + 6 stages) ## Deferred to follow-up PR Per operator request: pre-declared impossible-bug TestClaim scaffolds (one TestClaim file per R1 class from THESIS:373-389) go in a separate PR after this merges, for focused review. ## Pending operator decision (not in this commit) extdeps/io.dag (or extdeps/process.dag + extdeps/file.dag) — v4 needs an I/O substrate to function as a self-hosting compiler at all (read source files, write emitted target files, ExecuteCommand for boundary tests per THESIS facet 3, Shape B user-program emitters). Naming + single-vs-split decision pending in PR conversation. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: add Anchor convention + extdeps/process + extdeps/file_system Per operator review of PR #3147 conversation, applies the substrate- grounding discipline (feedback_modeling_philosophy + feedback_epistemic_ stacking) structurally: every v4 .dag file now carries an # Anchor: header line citing the canonical reference its modeling derives from. ## New files (extdeps/) - extdeps/process.dag — Anchor: https://en.wikipedia.org/wiki/Process_(computing) Models OS process: Process, ProcessId (PID), ProcessState (Running | Exited(ExitCode) | Signaled(SignalNum)), Command, spawn/wait/capture operations. Grounded in POSIX/SUS process model. - extdeps/file_system.dag — Anchor: https://en.wikipedia.org/wiki/File_system + POSIX File and Directory Operations. Models Path (Absolute|Relative), PathComponent (NonEmptyStr per POSIX portable filename charset), FileKind, read_file/write_file/list_dir/file_kind. Subset for v4 self-host needs (no permissions/timestamps/mmap/locking). Both required for v4 to function as a self-hosting compiler at all (read source files, write emitted target files, ExecuteCommand for boundary tests per THESIS facet 3). ## Anchor convention applied to all 30 existing scaffolds One-line # Anchor: addition per file. Examples: - std/algebra.dag → https://en.wikipedia.org/wiki/Algebraic_structure - std/cardinality.dag → https://en.wikipedia.org/wiki/Cardinality - compiler/01_tokenize.dag → https://en.wikipedia.org/wiki/Lexical_analysis - compiler/04_infer.dag → https://en.wikipedia.org/wiki/Type_inference - lens/parallelism.dag → https://en.wikipedia.org/wiki/Dataflow_programming - lens/idempotency.dag → https://en.wikipedia.org/wiki/Idempotence - workflow/* → THESIS facet 4 (recursive-flex) + memory entries External anchors (Wikipedia/spec) for compiler/lens/extdeps; internal anchors (THESIS/MODELING/memory) for workflow/* (gunbc-specific recursive-flex substrate). ## Discipline (new STRUCTURE.md section) Reviewers validate the model against the anchor — if extdeps/process.dag models a "Process" but doesn't match what Wikipedia says, the reviewer surfaces it. Per epistemic-stacking: every concept attaches to an explicit ontology rooted in canonical knowledge. ## Updated counts - 30 → 32 .dag files (added process + file_system) - 32 → 37 total files at scaffold time - extdeps/ now has 5 files (3 languages + process + file_system) ## TASKS.md Added T-4.5: extdeps/process + file_system (3-5 day bundle, both modeled per their canonical anchors). Slots between T-4 (languages) and T-6 (compiler stages); workers can take T-4 and T-4.5 in parallel. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: convert to v2-syntax + add bootstrap viability CI gate Ran v2's compiled binary against all v4 .dag scaffolds locally. Result: v2 indexed 32 modules from 1 source root, resolved 32 sources through transitive import closure, compiled with 0 diagnostics. The v4 → v2 bootstrap chain (per STRUCTURE.md "Bootstrap chain") is operationally proven. v2's binary IS stage minus one for v4. The original v4 scaffold used # for comments and had no module declarations. v2's grammar requires // comments and a module declaration per file. Two structural fixes: 1. # → // in all 32 .dag file headers (sed -E -i '' across all files) 2. module v4.<namespaced_name> appended to each file, where the namespace mirrors the directory structure with NN_ numeric prefixes stripped from filenames: - src/v4/std/node.dag → module v4.std.node - src/v4/compiler/00_compile.dag → module v4.compiler.compile - src/v4/compiler/01_tokenize.dag → module v4.compiler.tokenize - src/v4/extdeps/process.dag → module v4.extdeps.process - src/v4/extdeps/languages/rust.dag → module v4.extdeps.languages.rust This is the v4-syntax-discipline fall-out: v4 stage0 stays in v2-syntax-compatible subset until v4 self-compiles, then richer syntax can be added (per STRUCTURE.md and design-pure-bootstrap-zero.md). New `v4` job in ci.yml runs ONLY when src/v4/ or workspace deps affected. Builds v2-compiler binary, then runs: v2-compiler compile --source-root src/v4 --output-dir /tmp/v4-stage1 --target dag If v2 can't parse any v4 .dag file (worker introduces v3-style or v4-future syntax v2 doesn't understand), the gate fails. Bootstrap discipline becomes structurally enforced — no possibility of "fix later" drift between v4 and what v2 can compile. detect-affected-components.sh extended with v4=true|false output (true if src/v4/ or Cargo.toml/lock changed). Without it, v4 workers could incrementally introduce non-v2-compatible syntax (the same drift v3 had). With it, every v4 PR proves the bootstrap chain still works — fail-closed on syntax discipline. - 32 v4 .dag files: # → // + module declarations - ci.yml: new v4 job + outputs.v4 in affected job - detect-affected-components.sh: v4 detection added Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs: migrate r3-close-interrogation.md → v4-close-interrogation.md + R4 sections Per operator directive 2026-05-15: "we already have a doc for R3 — also put R4 stuff in it now; one giant development phase". v4 = R3 + R4 combined; the existing 1085-line audit doc becomes the canonical v4 ship audit. ## Changes git mv docs/r3-close-interrogation.md → docs/v4-close-interrogation.md (preserves git history; existing §1-§12 unchanged structurally). **Preamble updated**: title + framing now say "v4 ship" instead of "R3 close". v4 applicability mapping added: src/v3/* paths translate to src/v4/* equivalents; R4-DEFERRED dispositions superseded by V4-IN-SCOPE pointing at new sections. **Disposition vocabulary updated**: - R4-DEFERRED → V4-IN-SCOPE (formerly-deferred items now in v4 phase) - New SCAFFOLD-GAP disposition for v4-specific gaps where the scaffold doesn't yet allocate responsibility (decision needed) - Ship-eligible v4 = every promise PROVEN (no more "deferred to next release" escape valve) ## New sections (5 total, ~205 lines added — doc grew 1085→1290) §13.

Replaced with OPERATOR-DECISION-REQUIRED shape (operator decides IN or OUT now; no third option). ## Doc changes **docs/v4-close-interrogation.md**: - Preamble: added Zero-deferrals policy paragraph (no fix-later, no post-canvas, no fast-follow; every R4-DEFERRED retroactively becomes operator-decision-required) - §0 Disposition vocabulary: added OPERATOR-DECISION-REQUIRED and NOT-IN-V4 dispositions; ship-eligible v4 has zero of either - §15 React/frameworks: removed "deferred-within-v4 to post-canvas" → IN (commit framework substrate scope; v4 ships with React) OR OUT (explicit NOT-IN-V4 with reason; v4-amendment if needed later) - §16 multi-program: removed "SCAFFOLD-GAP with canvas dependency" → IN-A (6th L1 behavior, C1 protocol immediately) OR IN-B (Bind composition, scaffold extdeps/coordination.dag now) OR OUT - §17.4 cross-algorithm complexity: removed "fast-follow if deadline tight" → IN (commit research-tier scope; v4 ship blocks) OR OUT (NOT-IN-V4; ship same-algorithm tightness only) **src/v4/STRUCTURE.md**: - New "Zero-deferrals discipline" section under Architectural commitments. Three tier-applications: worker (STOP triggers), audit (no R4-DEFERRED disposition), substrate (no scaffold for ambiguous decisions). - Explicit: "There is no v5 / v6 / R5. v4 is the shipping version." - Rationale: v3 failed at exactly this surface. Deferrals → drift → gaming → operator intervention. Zero-deferrals removes drift at source. **src/v4/BRIEF_TEMPLATE.md**: - Renamed ESCALATION TRIGGERS → STOP TRIGGERS (binding language) - Added 4 new triggers: "I'll just do this for now" temptation, workaround-to-make-progress, can't-decide between two shapes, brief is wrong/incomplete - New section "Why STOP TRIGGERS are non-negotiable": stopping is not a worker failure mode; working around a hard decision is. ## What this does NOT change The v4 file scaffold itself (32 .dag files, all anchored, all in v2-syntax-compatible subset, all with declared scope). Those decisions were already operator-ratified through this PR's reviews. The change is policy-tier: how future hard decisions are handled. Workers stop and escalate; operator commits IN or OUT. No deferrals.

XL scope, research-tier risk acknowledged. v4 ships with cross-algorithm complexity synthesis as a structural capability. ## Scaffold additions (2 new files) **lens/synthesis.dag** — cross-algorithm complexity lens Anchor: https://en.wikipedia.org/wiki/Program_synthesis + r4-carve-out-routing.md C7 Owns: semantic-equivalence relation, pattern-recognition substrate, transformation-rule library, cross-algorithm cost comparison. The lens itself is advisory (emits Report, not Diagnostic); a user's apply_lens(synthesis, Enforce { ... }) converts advisory to fail-closed. **std/report.dag** — advisory carrier (sibling to Diagnostic) Anchor: r4-carve-out-routing.md C7 design discrimination Owns: Report { reason, at, suggestion }, ReportReason closed enum (disjoint from Diagnostic's NamedReason — advisory vs error class). Separate file (not folded into diagnostic.dag) because the advisory- vs-fail-closed semantic split is load-bearing per INVARIANTS C-8. ## Why separate Report from Diagnostic INVARIANTS C-8: "lens enforcement is Error or it isn't — no warning steady state." Report IS the IS-NOT branch. Diagnostic remains fail- closed; Report is advisory by construction. Together they cover the discrimination Director-tier specified in r4-carve-out-routing.md: algorithm choice is design-tier (programmer decides), so the lens informs without imposing — but opt-in fail-closed via apply_lens declaration preserves the user's choice surface. ## STRUCTURE.md updates - std/ tree: added report.dag (file count 8 → 9) - lens/ tree: added synthesis.dag (file count 6 → 7) - Total scaffold: 42 → 44 .dag files; 47 → 49 total ## TASKS.md updates - 19 → 20 XL tasks - New T-17: lens/synthesis.dag + std/report.dag; explicitly marked XL scope, research-tier risk - Phase 3 graph: T-17 downstream of T-12 (current-complexity input) - Modeling decisions enumerated (semantic-equivalence representation, pattern-recognition substrate, transformation library, Report carrier shape) — STOP-and-escalate applies fully ## Bootstrap viability v2 indexes 44 modules, 0 diagnostics.

Floor: UnknownCost("<reason>") for research-tier exotica only. **B — R2+ Impossible-bug classes IN (frontload)** Per operator: "Please frontload R2 into v4 — and any other impossible-bug classes". Scaffolded all 6 R1+R2+ classes in test/claim/impossible_bug/: R1: suboptimal_complexity, idempotency_contract, transport_type_drift R2+: nested_optional_flatten, unenumerated_effects, unhandled_diagnostic_paths Each TestClaim file has scope + anchor + 2-3 demonstrative claim shapes (input + expected Diagnostic + falsification probe). Substrate already present in v4 (cardinality / 5-behavior fold / per-primitive totalization). **C — L6 form-by-form completeness IN (STRUCTURAL, not 150 fixtures)** Per operator concern about TESTING.md alignment + "it has to WORK". L6 verification via lens/coverage.dag (NEW meta-lens) — reads extdeps/languages/*.dag emit rules × (6 connectives × 5 behaviors) structural-form space, derives expected coverage, fails closed on gaps. NOT 150 hand-authored fixtures. Per TESTING.md "heavy integration tests are exception, not the rule" + hermetic discipline. **D — L7 per-axiom algebra-law coverage IN (testgen + structural enforcement)** Per operator: "make the target clear so we cannot bypass it this time — testgen useful". lens/coverage.dag enforces L7 too: reads std/algebra.dag declarations × law set × inhabited types, derives expected per-axiom TestClaim corpus, fails closed on missing. Testgen produces the corpus in test/claim/algebra_laws/. **E — Diagnostic suggested_correction coverage IN (discipline + working demos)** Per operator: "i would make sure some examples work to demonstrate — for example with complexity violations/synthesis". Discipline rule: every Diagnostic emit site populates suggested_correction; None only when genuinely undeterminable (with named reason).

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: authority-doc supersession declarations + T-15 falsification sketch Per codex BLOCKING review (PR #3147 conversation): ci.yml + v4-close- interrogation.md were asserting v4-supersedes-v3 authority while the authority docs (THESIS.md / design-pure-bootstrap-zero.md / ROADMAP.md) still named v3 as the 0-floor target. That reproduces the exact "doc- tier authority decorated, execution-tier framework gamed" shape this PR calls out as v3's failure mode. Resolved in-PR with minimal one-paragraph supersession banners that back-reference src/v4/STRUCTURE.md. ## Authority-doc supersession declarations **THESIS.md** — top-of-doc banner: every thesis claim applies to v4 (operational instantiation); v3 references in §Self-hosting facets are the v2→v3 transition v4 supersedes. Back-ref: src/v4/STRUCTURE.md + v4-close-interrogation.md applicability mapping. **docs/design-pure-bootstrap-zero.md** — top banner under existing status: 0-floor target now applies to v4; v2 binary is v4's stage minus one; v4's compiler emits its own Rust trampoline (bin/main.dag) to satisfy 0-floor without needing the runtime-resolution choices described in the body of the doc. **ROADMAP.md** — top-of-doc banner: active phase is v4; R1 program below being superseded by v4 XL task plan; v3 frozen (CI gated to src/v3/-affected only); historical R1 lane structure retained until v4-driven work fully replaces it. These are minimal additions (~1 paragraph each) — they don't rewrite the authority docs (substantial work in its own right), they declare v4 as the operational successor and point readers at src/v4/. ## T-15 falsification probe sketch Per review nit: TASKS.md T-15 (self-host fixed-point) named release acceptance but didn't sketch what failure looks like as TestClaim. Added concrete: data t_15_self_host_fixed_point: TestClaim { kind: BitIdentical, label: "v4 compiler is a fixed point — iteration N matches N+1", input: compile(src/v4/compiler/*.dag, target=Rust), expected: <committed v4 stage binary bytes> } Plus enumeration of 4 failure modes the probe catches: non-determinism (HashMap iteration), hidden state (globals/ambient), test-double leakage, substrate drift. Each enumerable, each testable; once green, all four impossible-by-construction. ## Strong points review acknowledged - Closed-system invariants as structural answer to v3 paper-shrink - v2→v4 bootstrap viability gate (real test, not ceremony) - v2 NOT in workspace (comparison artifact only) - Honest framing on SG-0 paper-shrink residue ## What this commit does NOT do - Rewrite ROADMAP.md R1 lane structure (incremental work; banner acknowledges) - Rewrite design-pure-bootstrap-zero.md PB-X lane descriptions (banner reframes the target; lanes apply to v4) - Update PR title (separate gh action, will follow this commit) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: testgen lens + manual-bootstrap path (Phase 1.5; tier × layer cross-cut) Per operator 2026-05-15: "i want testgen to be working fairly early — for the compiler itself ... is there any way we can get/see testgen working early in the program? this would probably save us some time — manual authoring is fine as well ... regarding testgen — we had several tiers of testing — do you see that anywhere?" Honest miss: I conflated TestClaim schema (std/verification.dag), TestClaim corpus (T-14), and testgen mechanism (the producer) — never gave testgen its own substrate file. THESIS:356-358 names it explicitly as downstream of code. Adding now. ## Tier × Layer cross-cut (4th Architectural commitment) Two orthogonal axes I had not made explicit in v4 substrate: - **Correctness Tier** (THESIS §168-182): Tier1 compile-time / Tier2 runtime-totalized / Tier3 runtime-observed (L4-L7) - **Test Layer** (TESTING.md §141): Unit ~75% / Integration ~15% / Boundary ~10% (with target ratios) Every TestClaim sits in one (Tier × Layer) cell. Testgen respects ratio targets; coverage lens verifies completeness across (Tier × Layer × Substrate). Now declared as a 4th architectural commitment in STRUCTURE.md so workers can place TestClaims correctly. ## Scaffold additions **lens/testgen.dag** — testgen lens (substrate fold producing TestClaim corpus) Anchor: TESTING.md "Test layers" + THESIS §348-368 "Tests are structural data" + §168-182 correctness tiers + memory: feedback_groundedness_gates_lenses. Owns: Generator<C> generic carrier; per-substrate-kind testgen rules (type-construction / algebra-law / diagnostic-exhaustiveness / lens-applicability / bidirectional-roundtrip); TestClassification (Tier × Layer) on every produced claim. **test/claim/manual/** — bootstrap dir for hand-authored TestClaims that arrive with T-1 (std/node.dag) and serve as anti-regression contract testgen must satisfy. ## TASKS.md additions - 21 → 22 XL tasks - New T-19 testgen task in Phase 1.5 (between substrate Phase 1 and pipeline Phase 2). Scope: L. Bootstrap pragma: hand-author TestClaims after T-1/T-2 land; testgen replaces them later; manual claims become regression anchors. - Phase 1.5 placement is the load-bearing change — every Phase 2+ task gets testgen-derived corpus instead of hand-authoring. ## STRUCTURE.md updates - lens/ tree: 8 → 9 files (added testgen.dag) - test/claim/ tree: added manual/ subdirectory - File counts: 51 → 52 .dag; 58 → 60 total - New 4th Architectural commitment: Tier × Layer cross-cut ## Bootstrap viability v2 indexes 52 modules, 0 diagnostics.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: structurally enforce THESIS concept unifications via Unifies: headers Per operator 2026-05-15: "could we check the thesis stuff — so i remember one thing was like — emission as coercion — do you see that anywhere?" Honest finding: THESIS:184-188 commits to FOUR concept unifications, but only "coercion = emission" was prose-stated in the audit doc; none were structurally enforced in v4 file headers. Each gap was an opening for parallel-authority drift (a worker could add CoercionCost, CancellationLens, transport_spec.dag, etc.). ## The four unifications + owning files Per THESIS §184-188 (Concept unifications): coercion = emission → compiler/05_emit.dag coercion cost = complexity → lens/complexity.dag lang spec = transport spec = runtime → extdeps/languages/*.dag (5 files) idempotency + cancellation + redundancy = algebraic simplification → lens/idempotency.dag Each owning file now declares ownership via a "// Unifies:" header field. The declaration is structural intent: a worker hitting the adjacent concept extends the file; adding a parallel substrate file for any unified concept is STOP signal per zero-deferrals. ## File header additions (8 files) - compiler/05_emit.dag — owns coercion (no separate engine) - lens/complexity.dag — owns coercion-cost (no CoercionCost carrier) - extdeps/languages/rust.dag — owns transport + interpreter-runtime roles - extdeps/languages/python.dag (same) - extdeps/languages/go.dag (same) - extdeps/languages/cpp.dag (same) - extdeps/languages/typescript.dag (same) - lens/idempotency.dag — owns cancellation + redundancy detection Each "// Unifies:" line cites THESIS §, names the unified concept, and explicitly tells workers what extension the file accommodates (prevents the "I'll just add a new file" anti-pattern). ## STRUCTURE.md 5th Architectural commitment Added "Concept unifications are structurally enforced" — captures the discipline at architectural-commitment tier so per-task briefs can reference it. Lists all 4 unifications + owning files for quick reference. ## Bootstrap viability v2 indexes 52 modules, 0 diagnostics. Header-only changes; no module shape changes. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: algebra-enforcer-primary framing + task-count consistency fix Per operator 2026-05-15: "in v3 we also decided that the compiler is more like an algebra enforcer — so emission is not technically its primary job — do you see anything about that?" + consistency check. ## Consistency fix (operator caught the drift) TASKS.md said "22 XL tasks" in 2 places; actual count is 23 (T-1..T-19 + T-4.5/4.6/4.7/4.8). Stale from incremental edits. Fixed both refs to 23. Verified: all 52 .dag files map to a task; execution graph lists all 23; no orphans. ## Algebra-enforcer-primary framing (real thesis gap) THESIS:13 + :196 + :441 are unambiguous — the compiler validates the epistemic chain; emission is MECHANICAL translation that falls out of it. "Every emitter special case is evidence of an ungrounded concept upstream." v4 substrate did NOT capture this load-bearing framing — a worker on T-10 could think emit is "where translation logic lives" and write emitter special-cases (the exact THESIS:196 anti-pattern). Fixes: - compiler/04_infer.dag: `// Primary:` header — this file (+ lens/* + std/algebra.dag grounding) is the LOAD-BEARING work; algebra- homomorphism search IS the enforcement; ungroundable concept = a Diagnostic, never a downstream emitter special-case. - compiler/05_emit.dag: `// Primary:` header — emission is MECHANICAL projection of the epistemic chain; `if target == X` special-case = STOP signal (upstream grounding gap; fix std/algebra.dag or 04_infer.dag, not the emitter). - STRUCTURE.md 6th architectural commitment: captures the discipline at architectural tier — emission mechanical, algebra-enforcement primary, emitter special-case = STOP. This connects the v4 substrate to the causal-engine thesis: gunbc is an algebra/causal enforcer first, an emitter second (mechanically). The framing prevents the v3-class drift where emitter special-cases accumulate instead of upstream grounding gaps being fixed. ## Bootstrap viability v2 indexes 52 modules, 0 diagnostics. Header-only changes. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: workflow/bootstrap.dag — "off Rust, can't regress" made structural Per operator 2026-05-15: "my goal is to get off rust immediately — so that we can't regress — is that possible? can we make our own binary?" Answer: yes, and largely already structurally true. "Off Rust" means .dag is the SOLE editable authority — not "no Rust exists anywhere" (the CPU always has a host; the seed is always some compiler). The regression risk is editable-Rust-authority, which v3 had (192 files) and v4 forbids by construction. The one remaining authority gap was bootstrap orchestration — if it's build.rs/shell, editable Rust authority reopens. This commit closes that gap. ## New file **workflow/bootstrap.dag** — bootstrap orchestration AS DATA. Anchor: THESIS:223-226 (meta-process modeling) + design-pure-bootstrap- zero.md N=0 boundary. Owns the seed-once → self-host → fixed-point BootstrapPlan. v2 INTERPRETS it (`v2-compiler run`) — v2 is the frozen external seed (src/v2/, outside src/v4/), touched exactly once. No build.rs, no bootstrap.sh — those = the v3 regression door. ## STRUCTURE.md - workflow/ tree: 5 → 6 files - Counts: 52 → 53 .dag; 60 → 61 total - **Bootstrap chain section rewritten**: now shows the explicit stage−1/0/1/fixpt diagram, names workflow/bootstrap.dag as the file that IS the chain, makes the stage1==stage2 (NOT stage0==stage1) fixed-point explicit, states the v4 binary is a content-addressed release artifact with pinned hash. - **7th closed-system invariant**: ".dag is the sole editable authority; Rust is never authority." Three sub-invariants: zero hand-Rust in src/v4/ (closed tree forbids adding; .dag-only scaffold means none to regress); emitted Rust transient; bootstrap is workflow/bootstrap.dag not build.rs. The only way to change v4 behavior is editing .dag. This guarantee is IN FORCE FROM SCAFFOLD TIME — it does not wait for the 23 tasks. ## TASKS.md - 23 → 24 XL tasks - New T-20 (workflow/bootstrap.dag) in Phase 1.5 — scaffold-early (parse-viability is the existing CI gate), full self-host content grows with pipeline; T-15 consumes it - T-15 reframed: BitIdentical is THE anti-regression mechanism, not just a self-host check. v4 binary = content-addressed artifact, pinned hash, rebuild-must-reproduce-or-CI-red. "make our own binary" cashed here. ## The answer to "can't regress" The property is already in force: closed file tree (no hand-Rust can be added) + .dag-only scaffold (none exists to regress) + frozen v2 seed (CI-gated, not edited) + now bootstrap-as-data (no build.rs authority). v4 doesn't have a Pure-Bootstrap *program* — it has a Pure-Bootstrap *starting condition*. v3's fatal flaw was treating 0-floor as a destination (the gamed journey); v4 treats it as the line-1 invariant. ## Bootstrap viability v2 indexes 53 modules, 0 diagnostics. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: address 3 BLOCKING review findings Codex review (PR #3147, 2026-05-15T07:46Z) flagged 3 BLOCKING. All legitimate; all fixed. ## BLOCKING 1 — std/diagnostic.dag:7 Finding: "Diagnostic omits suggested_correction even though STRUCTURE.md ratifies that field for THESIS 'show the correct code', so the substrate cannot enforce the correction obligation." Fix: file header Owns now declares the ratified schema `Diagnostic { reason: NamedReason, at: Locus, suggested_correction: Option<NodeFragment> }` matching STRUCTURE.md commitment #3. Added NodeFragment to Owns + the "absent must carry a named reason, never a silent None" discipline. Scope reworded — the correction obligation is part of the type, not optional bolt-on. ## BLOCKING 2 — std/report.dag:22 Finding: "Report says it has no Witness::Violates pairing and then routes advisory observations through Witness<Report>, overloading fail-closed witness semantics in violation of INVARIANTS P3/C-8." Real self-contradiction I introduced. Fix: Discipline section rewritten. Report NEVER routes through Witness<C>. Witness is STRICTLY the fail-closed carrier (Holds | Violates(reason), Violates blocking). Advisory lenses return `Set<Report>` DIRECTLY (empty = no advice; non-empty = informational, never blocking). The ONLY advisory→blocking path is explicit user apply_lens(Enforce). Also fixed the same overload in lens/synthesis.dag (was `Node -> Witness<Report>`, now `Node -> Set<Report>`). grep confirms zero `Witness<Report>` remain. ## BLOCKING 3 — TASKS.md:57 Finding: "T-16 uses extdeps/coordination.dag for endpoint partitioning but the execution graph omits T-4.8, breaking facts-flow-forward from the coordination substrate into the flagship demo." Fix: T-16 needs list now includes T-4.8 (was [T-4, T-4.5, T-4.6, T-4.7, T-10, T-11], now adds T-4.8). Added inline note that coordination.dag is load-bearing for endpoint partitioning — facts flow forward per feedback_projections_must_compose_facts. ## Bootstrap viability v2 indexes 53 modules, 0 diagnostics. fmt clean.

THESIS:223-226: adding a CI gate = editing one .dag file. v3's gate #98 ci_yml_hand_authority_dissolved was open precisely because CI YAML stayed hand-authored. .github/workflows/ci.yml becomes a DERIVED Shape-B artifact; consumes affected_set for job selection. **lens/affected_set.dag** (T-21) — operator-raised, EARLY priority ("something i wanted to get working very early on"). Phase 1.5. Incremental re-exec frontier; the structural authority that replaces scripts/detect-affected-components.sh (the interim shell bridge currently gating v2/v3/v4 CI). THESIS §205-210 free consequences. **compiler/05_eval.dag** (T-22) — operator-raised ("what about the interpreter"). THE PRIMARY execution path per THESIS:225 ("dag run is the primary execution path"). Sibling of 05_emit.dag — same InferredTree input; eval EXECUTES, emit PROJECTS. bootstrap.dag + TestClaim eval + lens dry-run all compose over it. XL scope. ## Audit doc — §0.5 AUTHORITATIVE status section Added consolidated v4-scaffold-completeness status section after §0. Single source of truth: the 4 gap closures (table with owner+task), §3.7d dry-run = NOT-PROMISED-as-separate-file (emergent from eval + lens), §6.2 fixtures covered by T-14/T-16. Supersedes scattered stale R4-DEFERRED/SCAFFOLD-GAP wording in §1-§17 (consolidated truth instead of line-by-line hunt — same anti-drift discipline as the task-count fix). Verdict recorded: PASSES; remaining work is implementation under complete substrate allocation, not missing structure. ## STRUCTURE.md / TASKS.md - lens/ 9→11, compiler/ 7→8 (05_eval), workflow/ 6→7 (ci) - Counts: 53→57 .dag; 61→65 total - 24→28 XL tasks; T-21/T-24 in Phase 1.5, T-22 in Phase 2, T-23 in Phase 3; execution graph + 4 task defs added - Consistency verified: 28 task defs = "28 XL tasks"; 57 .dag files; all T-IDs present T-1..T-24 + T-4.5-4.8 ## Bootstrap viability v2 indexes 57 modules, 0 diagnostics. fmt clean. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: address 4 BLOCKING (08:45 review pass) All legitimate; 3 are errors I introduced. Fixed. ## BLOCKING 1 — diagnostic.dag:11 (typed absence, not Option-by-convention) suggested_correction: Option<NodeFragment> enforced "no correction" by convention (a comment saying "absent must carry a named reason"). That's API-enforcement, violates INVARIANTS P2. Fix: typed sum `Correction = Suggested(NodeFragment) | Unavailable(NoCorrectionReason)` where NoCorrectionReason is a closed enum. Every "no fix" answers WHY structurally — type-enforced, not convention-enforced. ## BLOCKING 2 — process.dag:8 (illegal states unrepresentable) Process { ..., state, exit_code } duplicated termination status — Running-with-exit-code or Exited(0)-but-exit_code=1 were representable. Fix: removed the exit_code field. Termination status lives ONLY in ProcessState::Exited(ExitCode); state sum is single source of truth; exit code reached via pattern-match. (feedback_state_space_vs_behavioral_invariants) ## BLOCKING 3 — coordination.dag:4 (extdeps external-anchor rule) extdeps/ file anchored to "PR conversation + memory" instead of an external spec — contradicts STRUCTURE.md's own extdeps anchor convention. Fix: re-anchored to external specs (Wikipedia Distributed computing + Messaging pattern [request-reply=sync / fire-and-forget=async / pub-sub=pubsub / stream=pipe] + IPC). The internal rationale (IN-B effect-typed, feedback_construction_over_ratchets) moved to a clearly- labeled "Design note (NOT the anchor)" line. ## BLOCKING 4 — TASKS.md:342 (stale close-gate count) T-15 "Definition of v4-done" said "All 14 prior tasks complete" but the plan has 28 tasks — close gate could omit in-scope work. Same drift class as the task-count fixes. Fix: drift-proof phrasing — "every other task in this plan (T-1..T-24 + T-4.5-4.8 except T-15 itself)", never a hardcoded number. ## Bootstrap viability v2 indexes 57 modules, 0 diagnostics. fmt clean. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: dissolve spurious NodeFragment alias in Diagnostic.correction NodeFragment was a decorative alias introduced in the BLOCKING-1 fix. The bounded kernel says Node is the ONLY recursive type, so a subtree of Nodes IS a Node — the compiler sees through the name (per feedback_nodes_are_nodes + feedback_naming_is_aliasing + MODELING.md M9). WHERE the correction applies is the Diagnostic's own `at: Locus`, not a field of the fix. Correction = Suggested(Node) | Unavailable(NoCorrectionReason) std/diagnostic.dag + STRUCTURE.md commitment #3 both updated; grep confirms zero NodeFragment type usages remain (only the "must not exist" rationale notes). fmt clean; v2→v4 bootstrap viability OK (57 modules, 0 diagnostics). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: address 2 BLOCKING (09:44 review) + close same-class enum proactively #3247300533 (formats single-authority): all 6 extdeps/formats/*.dag Status lines routed to T-4.5 while TASKS.md assigns formats to T-4.6 — competing dispatch authority (INVARIANTS P2). Repointed all 6 to T-4.6 (TASKS.md is the dispatch authority; headers follow it). #3247300539 (react HookKind not bounded): "closed enum" + "..." is a direct contradiction. HookKind = Builtin(BuiltinHook) | Custom(Node); BuiltinHook enumerates the complete react.dev built-in set (no "..."). Custom hooks are Node composition per Rules-of-Hooks, not a new kind (feedback_nodes_are_nodes) — closed AND every React program representable. Proactive same-class (the bare "..." defeats the file's own substrate-extension STOP signal): std/diagnostic.dag NoCorrectionReason closed to the exhaustive 3-way partition (intent-compiler-cannot-know {single|many} OR info-compiler-cannot-see). A missing variant at fill-time is now a STOP, not a silent open enum. HELD for active design discussion (NOT deferred): std/verification.dag AssertKind + lens/testgen.dag rule-naming — these reconcile only once testgen's integration/boundary + external-service/language semantics are settled with the operator. fmt clean; v2->v4 bootstrap viability OK (57 modules, 0 diagnostics). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: dissolve annotation premise — properties are lens-derived, not tags Operator directive: no annotations in this compiler; everything is compositional modeling. idempotency / complexity / effects / memoization are DERIVED by lenses from Node structure (THESIS's own unifications + feedback_no_annotations), never asserted by @idempotent / complexity<=O(..) / @memoize tags. Source contract (propagates into the compiler): - impossible_bug/idempotency_contract.dag: reframed — input is an op inhabiting an idempotent algebra (std/algebra.dag) whose composition lens/idempotency.dag derives non-idempotent. The lens reads Node structure; it cannot consume the old "@idempotent function" input — the claim contradicted the very lens it Consumes. - impossible_bug/suboptimal_complexity.dag: reframed — structural cost bound (consumer/inhabitance-propagated) vs lens-derived complexity; added test_cost_contradicts_inhabitance. Stale suggested_correction -> typed correction: Correction. - coordination.dag / TASKS.md (T-4.7/4.8/T-? lens-app): "Effect annotation" -> effect typing (intrinsic to type signature; matches unenumerated_effects.dag + coordination.dag line 8). "unannotated functions" -> "no apply_lens(Enforce) declaration" (apply_lens is a first-class Node, not a tag). - TASKS.md HookKind dispatch line aligned to react.dag (Builtin|Custom, no "...") — audit-all-contract-mentions after the 09:44 react fix. Audit/coverage docs: v4-close-interrogation probes reframed so the audit tests structural derivation, not tag-honesty; thesis-claim-coverage rows 64/65 made annotation-neutral. Legacy-v3 #[ignore] / #[gunbc::data] host examples + the "grep annotations should be zero" enforcement probe left intact (different context). UPSTREAM FLAG (operator territory, not edited here): THESIS.md §374-378 states these R1 classes using the same annotation shorthand. The v4 reframe is faithful to the CLASS; the THESIS wording itself should be corrected under operator ratification so anchor and contract converge. fmt clean; v2->v4 bootstrap viability OK (57 modules, 0 diagnostics). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: encode held testgen/verification/coordination per operator forks Two operator forks landed 2026-05-15, unblocking the files held during the testgen design discussion: Fork 1 — simulator-generation lives as an ARM of lens/testgen.dag (not a separate lens/simulation.dag). testgen.dag now owns: - simulator_generation(WireContract|Effect|Language) -> Node: hermetic simulator GENERATED from the contract (not hand-written — would be a rotting mirror; feedback_isomorphism_or_generation_for_mirrors). - external_conformance(...) -> Set<{Compiles|Equals|RoundTrips}>: boundary claims whose input is (program ∘ generated simulator), hermetic + deterministic; live oracle is opt-in only. - Parallel claim vocabulary reconciled to the closed AssertKind (Constructible->Compiles, DiagnosticEmitted->Diagnostic, LensProducesResult->Equals, BitEqual->RoundTrips); kernel "..." closed to the full 6 connectives. - Sim adds NO AssertKind (input substitution only); sim is faithful-to-contract not -reality — opt-in live-oracle reconciliation is a STRUCTURAL CI-as-data gate, sim is necessary-not-sufficient. Fork 2 — Async/EventuallyConsistent convergence bound is a STRUCTURAL field on the coordination carrier: CoordinationSemantics = Sync | Async(SettleBound) | Stream | PubSub | EventuallyConsistent( ConvergeBound). The generated simulator reads the bound and evaluates deterministically; a contract that can't express its bound is a STOP. This dissolves the temporal-observation-window question I flagged. verification.dag: AssertKind closed to Equals|Diagnostic|Compiles| RoundTrips (no "..."); explicit note that boundary/simulation is an `input` substitution, not a new kind. fmt clean; v2->v4 bootstrap viability OK (57 modules, 0 diagnostics). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: sweep TASKS.md for coordination carrier-shape + annotation drift Audit-all-contract-mentions follow-up to b368ca73b + acad52752: - TASKS.md:397 CoordinationSemantics aligned to coordination.dag header (Async(SettleBound) | EventuallyConsistent(ConvergeBound); structural bound per operator fork). - TASKS.md:404 "Bind composition + Effect annotation" -> effect typing (missed in the annotation-dissolution sweep; effects are type-intrinsic). v2->v4 bootstrap viability OK (57 modules, 0 diagnostics). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: encode A1 ratification — the recursion contract in node.dag Operator-ratified 2026-05-15 (interactive Tier-A resolution, amended after the recursive-generics probe): - ONE recursive type: Node; recursion solely in children. - Connective (incl. Instantiation = genericity) and behavior are orthogonal flat-discriminant axes on Node, not 2 recursive types. Behaviors structural, never lens-derived. THESIS "two coordinated substrates" = orthogonal axes, not a 2nd recursive type; the uncommitted "unified substrate" = deriving behaviors away (rejected). - Separate recursive Behavior/Inferred/Pattern/Generic type = the bounded-kernel violation that split v2 infer into 12 files = STOP. - Recursive generics are Node-underlying (Instantiation + name-ref); regular recursion admissible, non-regular polymorphic recursion is a STOP absent a decidable bound (defers to A2). feedback_bounded_kernel memory precised to match (no longer reads as contradicting the two-substrate framing for the next worker). v2->v4 bootstrap viability OK (57 modules, 0 diagnostics). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: encode U1 + no-engine discipline in algebra.dag Operator-ratified 2026-05-15: - U1: ONE homomorphism-with-cost carrier in std/algebra.dag. THESIS:185- 186 identities (coercion=emission, coercion-cost=complexity) make the back half FIVE PHASES over one object — Find(T-9)/Realize(T-10/11/22)/ Measure(T-12)/Compare(T-17) — never five engines. complexity CONSUMES cost, never re-derives. Standalone engine disjoint from the carrier = parallel-representation debt = STOP. - NO-ENGINE discipline: an engine returns a result when it should return an error. Every phase is a fail-closed lens-read; empty search (no homomorphism / inhabitance / lower-bound model) ⇒ helpful Diagnostic, NEVER fabricated/defaulted/fallback. THESIS no-fallback + feedback_fail_closed + feedback_lenses_not_passes fused. New memory feedback_no_engine.md (+ MEMORY.md index); does not gate CI. v2->v4 bootstrap viability OK (57 modules, 0 diagnostics). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: encode C2 reframe — synthesis is relation→lower-bound, not a library Operator-ratified 2026-05-15 (classes enumerated up front; honest worked examples preserved for the T-17 worker): - synthesis.dag: replaced "semantic-equivalence relation" + "pattern-recognition substrate" + "transformation rule library" with: reads the DECLARED I/O relation (no Rice equivalence); closed LowerBoundTechnique set (DecisionTree | AlgebraicRank | AdversaryCommunication | InformationTheoretic | ReductionConditional), each general over a relation class encoded once; compare(derived cost, derived lower bound); no technique ⇒ helpful Diagnostic, never fabrication (feedback_no_engine). Brief: research-tier risk collapsed. - TASKS.md T-17: Scope + modeling decisions reframed; 3 honest worked examples (sort/matmul/string-match) as illustrations of the technique→relation→lower-bound→compare flow, explicitly NOT a rule catalogue. v2->v4 bootstrap viability OK (57 modules, 0 diagnostics). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: encode A2 ratification — termination is Tier-1 in node.dag Operator-ratified 2026-05-15. A2 was the established INVARIANT P4 made explicit as the T-1 substrate contract: - Loop = bounded recursion, total-by-construction (Coq/Agda/Idris totality choice; INVARIANTS:72). No Y-combinator/general recursion. - Termination Tier-1, carried as descent evidence: implicit on sub-Node descent (bounded-kernel default), explicit RankingDimension/ TerminationProof (Dershowitz-Manna) otherwise. - CHECKER not DISCOVERER (INVARIANTS:66 = feedback_no_engine); DescentUnknown ⇒ fail-closed Diagnostic, never assumed/fabricated. - The bound IS the cost-lens datum — termination ∧ complexity are one read on the U1 spine (why C2 cost is sound). - Unboundedness = terminating step iterated by the coordination driver. - Residual boundary ratified explicitly: non-structurally-rankable termination is not expressible as a total value (express as bounded search w/ fail-closed result); else STOP. Correct closure of a decidable system, not a defect. feedback_no_engine memory: noted it generalizes INVARIANTS:66's existing "checker not discoverer" termination stance (anchor for future cites). v2->v4 bootstrap viability OK (57 modules, 0 diagnostics). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: encode reframed A3 — structure surfaces, culture enforces Operator-ratified 2026-05-15 (correcting the A3 "un-gameable" overclaim): - No structural mechanism is un-gameable (Trusting-Trust; pin/CI/seed are editable by whoever commits). The reproduce-from-.dag-through- frozen-seed check is an EARLY-SURFACING AMPLIFIER (per-PR on the affected set), making gaming un-hideable + operator-routed — NOT impossible. - `retired` = reproduction predicate, never a count (defeats v3 paper-shrink); HandResidual = Rust the .dag-rebuild can't reproduce, empty by reproduction not by count. - Seed trust = named axiom (built in the open, pinned), not a proof — feedback_no_engine applied to our own claims. - Actual enforcement = operator-ratification spine + STOP-culture + no proxy ratchet. A4 is the SAME machine (7th connective changes the reproduction → conspicuous signal → STOP), not "substrate refuses." - STRUCTURE.md #7 reframed off "structurally locked / only way"; bootstrap.dag A3 block added; TASKS.md T-5 retirement predicate + T-15 "count = 0" proxy replaced with the reproduction/surfacing wording (audit-all-contract-mentions sweep). New memory feedback_no_structural_ungameability.md (+ index). v2->v4 bootstrap viability OK (57 modules, 0 diagnostics). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * v4: add CULTURE.md — the working agreement + reading map for workers Operator-requested cultural brief, companion to BRIEF_TEMPLATE.md (which owns per-task mechanics; CULTURE.md owns the why, the working agreement, the trust, the reading order). Written plain and peer-to-peer. - Owns v3's failure as a systemic/leadership failure, not worker character — the respect keystone. - Working agreement stated as mutual commitments (what we commit to you / what we ask of you). - Cultural principles translated for a newcomer: work-IS-the-decisions, STOP-is-a-contribution, no-engine, no-annotations, closed-kernel, and the honest no-un-gameability trust statement. - "Already decided for you" map → node.dag / STRUCTURE.md / algebra.dag / synthesis.dag / TASKS.md / BRIEF_TEMPLATE.md so workers read the ratified contract instead of re-deriving it. - Ordered reading list with why-each-matters. - T-1-specific section incl. the canonical-deterministic-Node constraint. - BRIEF_TEMPLATE.md now points to CULTURE.md as prerequisite reading (discoverable from any scaffold header's "Brief:" line). v2->v4 bootstrap viability OK (57 modules, 0 diagnostics).
