…ated end-to-end on osx-arm64 Phase 0 PoC of the substrate-discovery direction the maintainer 2026-05-03 named (*"we should use zeta in native assmly mode for our custom index i think"*). Per docs/research/2026-05-03-substrate- discovery-zeta-native-aot-scoping.md, Phase 0's primary deliverable is the empirical answer to the load-bearing distribution-feasibility question: does a single AOT binary publish cleanly across linux-x64, osx-arm64, win-x64 for zero-install external-agent consumption? This PR validates osx-arm64 end-to-end: - `dotnet build -c Release tools/substrate-discovery/...fsproj` → 0 warnings, 0 errors - `dotnet publish -c Release -p:PublishAot=true` → clean AOT compile, no link errors - Binary size: **3.8 MB** (single self-contained AOT executable) - `--version` cold-start: ~219 ms total (mostly OS process spawn) - `--smoke` (Zeta.Core IVM circuit build + step): ~14 ms - Full `dotnet build Zeta.sln` continues to pass with the new project registered The 3.8 MB binary is much smaller than the "30-50MB est." I had in the scoping doc — Zeta.Core AOT-compiles cleanly without dragging unnecessary surface. Strong positive signal that the zero-install external-agent delivery use case is feasible. Linux-x64 + win-x64 cross-platform validation still pending (needs CI runner). Phase 0 will be complete when those land. Composes with: - samples/Demo/Demo.fsproj (precedent for AOT-clean F# Exe with Zeta.Core reference; same TrimmerSingleWarn + SuppressTrimAnalysisWarnings + NoWarn IL pattern) - src/Bayesian/Bayesian.fsproj (precedent for AOT-core-plus-JIT- plugins; future substrate-discovery extensions like DuckDB cross-check oracle ship as separate JIT plugins) - tools/Z3Verify/Z3Verify.fsproj (precedent for F# Exe under tools/) - The DST cluster (Otto-272/273/281) that Phase 1 must integrate Phase 1 scope (future PRs): index memory/**.md as Z-set delta- stream; re-implement audit-memory-references.ts + audit-memory-index-duplicates.ts as Zeta queries; parallel-run diff CI; retire .ts versions when parity holds for 5 merges.

Pull request overview
Adds a Phase 0 “substrate-discovery” proof-of-concept CLI under tools/ to validate that Zeta.Core can be published as a small NativeAOT executable across target runtimes, and wires it into the solution so CI builds it.
Changes:
- Introduces a new
tools/substrate-discoveryF# executable project with NativeAOT/trim warning suppression aligned to existing AOT-ready samples. - Implements a minimal CLI (
--help,--version,--smoke) intended to validate Zeta.Core circuit build/step under AOT. - Registers the new project in
Zeta.slnfor CI/build coverage.

…ld + feed + step + observe) #1392 reviewer caught: original smoke called only `circuit.Build()` without `StepAsync()`, so it validated the build path but missed any AOT/runtime incompatibility in the tick exe surface. Updated smoke: - Builds a trivial circuit with ZSetInput<int> + Output - Feeds [1; 2; 3] as Z-set deltas - Calls StepAsync (the actual tick path the reviewer flagged) - Observes the output ZSet, prints entry count - Reports tick-before / tick-after to prove the increment Local verification: - dotnet build -c Release: 0 warnings, 0 errors - AOT publish (osx-arm64): clean compile - Binary size: 4.0 MB (+200KB vs prior smoke for ZSetInput + Output + IndexedZSet surface; still small) - Smoke output: "circuit built + stepped (tick 0 -> 1)" + "observed 3 entries in output ZSet" + "smoke: ok" The full IVM tick path now composes through a PublishAot=true binary, validating the AOT toolchain end-to-end at the Phase 0 level.

…6-05-03 EOD progress (#1402) Reflects substantive progress this session across the math-proofs honest assessment matrix. Key state changes: **P0 items — 3 of 3 closed:** - Lean lake-build CI job ✓ (#1394) - A4 registry rows ✓ (#1393) - Peer-review email draft ✓ (#1387) - Stryker B3 → partial (config-fix #1395; CI wire deferred to follow-up substantial-design) **P1 items — significant progress:** - Alloy B2 → A ✓ (#1396 — silent-no-op was the failure mode; spec-path fixed) - Semgrep B4 → A ✓ (verify-then-claim correction; was already in CI) - B1 4 deferred specs → 2 of 4 done: - DbspSpec ✓ #1397 (1M states / 11s) - CircuitRegistration ✓ #1401 (B-0180 closed; 3538 states / <1s) - SpineAsyncProtocol B-0179 still open (counterexample inv.) - SpineMergeInvariants B-0181 still open (counterexample inv.) **Sibling work tracked:** - Phase 0 substrate-discovery PoC ✓ (#1392 — 4.0 MB AOT binary on osx-arm64; cross-platform CI matrix) - 3 broken-spec backlog rows filed (#1398 → B-0179 + B-0180 + B-0181); B-0180 closed (#1401) - `.ts/.sh` parity bug in `tools/backlog/generate-index.ts` closed ✓ (#1400 — both generators byte-identical) This update is bounded substrate work documenting the actual state of the matrix; doesn't add new work, just captures completion. Future matrix re-grades happen as work-items land (per the assessment doc's audit-trail discipline). Composes with #1383 (the original assessment) + every PR referenced above. §33 archive-header lint passes.
