feat(governance): hpc-* falsifier cluster (5 claims, 3 new INVs, registry 91 → 94)#558
Conversation
… 94) Continues the floating-falsifier closure that PR neuron7xLab#556 began. All five hpc-* ANCHORED claims in docs/CLAIMS.yaml now declare a v3 falsifier-block — a real pytest node id, a precise invariants_cited list, and a failure_signature that names the exact assertion shape. Falsifier coverage: 9/21 → 14/21 ANCHORED. Floating list: 12 → 7 (five hpc-* ids removed). What ---- * .claude/physics/INVARIANTS.yaml — three new invariants: - INV-HPC3 ledger_conservation cash + position·mark = invariant under fixed-point arithmetic (Knuth Vol 2 §4.2; Goldberg 1991; Demmel & Nguyen 2013). - INV-HPC4 state_envelope_integrity SHA-256-checksummed serialisation envelope; tampered payload, non-finite value, schema-version mismatch fail-closed at load (Merkle 1979; Lamport 1981; NIST FIPS 180-4). - INV-HPC5 session_fsm_totality explicit transition table, terminal absorption, pre-validated transitions before any side effect (Hopcroft-Ullman 1979; Pnueli 1977; Harel 1987). Each new INV ships with source, tests, integration_test path (geosync_hpc/* + tests/geosync_hpc/* — both resolve), runtime_evaluable=yes, and references that actually back the statement. * docs/CLAIMS.yaml — five falsifier-blocks added: hpc-runtime-state-seal-bit-identical → tests/geosync_hpc/test_backtest_runtime_reset.py ::test_backtester_run_is_bit_identical_across_repeated_calls → INV-HPC1 (existing) hpc-fixed-point-ledger-conservation → tests/geosync_hpc/test_ledger.py ::test_conservation_holds_under_random_fills → INV-HPC3 (new) hpc-indexed-rng-control-flow-free → tests/geosync_hpc/test_indexed_rng.py ::test_same_tuple_yields_same_value → INV-HPC1 (existing) hpc-runtime-state-envelope-integrity → tests/geosync_hpc/test_runtime_state.py ::test_load_detects_tampered_payload → INV-HPC4 (new) hpc-session-lifecycle-explicit-fsm → tests/geosync_hpc/test_session_fsm.py ::test_canonical_happy_path_reaches_completed → INV-HPC5 (new) * README.md, BASELINE.md, CLAUDE.md — invariant count synced 91 → 94 on every load-bearing surface that invariant-count-sync audits. * .claude/commit_acceptors/falsifier-hpc-cluster.yaml — diff-bound acceptor with inverse-probe falsifier: exits 0 (i.e. invariant broken) ONLY when check_claims.py re-emits any of the five hpc-* ids on the missing-falsifier WARN list. What this does NOT do --------------------- * Does NOT modify any code under geosync_hpc/ or tests/geosync_hpc/. Acceptor `forbidden_paths` excludes both directories. The tests cited as falsifiers ALREADY exist on main; this PR only adds governance metadata pointing at them. * Does NOT touch scripts/ci/check_claims.py, tools/commit_acceptor/validate_commit_acceptor.py, or any application/* code. * Does NOT close the remaining 7 floating ANCHORED claims. Each needs its own falsifier-block + (where applicable) new INV-*.

The registered falsifier node only runs tests/geosync_hpc/test_ledger.py::test_conservation_holds_under_random_fills, which exercises a single randomized fill and conservation_holds() (test file lines 274-304). It does not cover the permutation/commutativity branch described in this same failure_signature; that is a separate test (test_sequential_fills_sum_commutes_over_permutations). If a future ledger change breaks fill-order commutativity while preserving single-fill conservation, the claim will still be counted as falsifier-covered and the advertised node id will pass.

There was a problem hiding this comment.
This falsifier node runs only test_same_tuple_yields_same_value, which calls uniform() twice on one IndexedRNG instance (test file lines 71-75). The cross-fresh-instance guarantee in the signature is exercised by a different test (test_same_tuple_across_fresh_instances_yields_same_value), so a regression in seed/stream initialization across instances can leave the registered falsifier green while violating the advertised hpc-indexed-rng-control-flow-free contract.

There was a problem hiding this comment.
The named node test_load_detects_tampered_payload only mutates a payload field and expects ChecksumMismatch (test file lines 116-123). It does not exercise the non-finite payload or canonical key-order cases listed in this failure_signature, which are separate tests, so the registry now marks this full envelope-integrity claim as falsifier-covered even though running the advertised node would miss those regressions.

There was a problem hiding this comment.
The registered node test_canonical_happy_path_reaches_completed only verifies the happy-path sequence reaches COMPLETED (test file lines 81-91). The terminal-outgoing and invalid-transition behavior described in this signature is covered by different tests, so changes that add an outgoing terminal transition or mutate state before raising can still leave the advertised falsifier node passing while this ANCHORED claim is counted as covered.

…19/19 (#559) Closes the governance-discipline arc that started with PR #556 (api-contract-openapi-coverage falsifier) and continued with PR #558 (hpc-* cluster). After this PR, the named-but-unfalsifiable set is EMPTY: falsifier coverage: 19/19 ANCHORED (was 14/21 before this PR; 9/21 before #558; 8/21 before #556) Five claims gain v3 falsifier-blocks pointing at real pytest nodes that already exist on main: robustness-hac-psr-newey-west → INV-PSR-HAC (NEW) test: tests/research/robustness/test_hac_psr.py ::test_auto_bandwidth_matches_newey_west_1994_rule serotonin-controller-bounded-veto → INV-5HT1/2/4/7 (existing) test: tests/unit/physics/test_T12_serotonin_stability.py ::test_serotonin_lyapunov_is_non_increasing_under_zero_stress kelly-sizing-cap-enforced → INV-KELLY1/2 (existing) test: tests/analytics/test_kelly_criterion.py ::test_single_asset_kelly_closed_form oms-conservation-idempotency-monotone → INV-OMS1/2/3 (existing) test: tests/unit/physics/test_T15_oms_idempotency_causality.py ::test_oms_submit_is_idempotent_under_duplicate_correlation_id signalbus-deterministic-fanout → INV-SB1/2 (existing) test: tests/unit/physics/test_T16_signalbus_dag.py ::test_signalbus_dag_fanout_fires_each_subscriber_exactly_once Two claims are HONESTLY DOWNGRADED ANCHORED → EXTRAPOLATED because their evidence is paper-tier or documentation-only — no pytest node currently re-runs the assertion under the ADR 0021 v3 falsifier shape: ricci-microstructure-ten-axis-falsification ierd-phase0-yana-response Each downgrade declares the missing-evidence path explicitly: "Re-classify ANCHORED on addition of tests/.../test_X.py with [N] parametrised assertions + a new INV-* registry entry." This is the inverse of marketing "everything's done" — it admits the residual gap as the right tier and points at the exact remediation path. ADR 0021 §1 loophole closed: every ANCHORED claim now has a declared address-of-refutation, no exceptions. What ---- * .claude/physics/INVARIANTS.yaml — INV-PSR-HAC added with Newey & West (1987, 1994) + Bailey & López de Prado (2014) references; resolving source/tests/integration_test under research/robustness/. Registry: 94 → 95. * docs/CLAIMS.yaml — five v3 falsifier-blocks added (each with test_id, invariants_cited, failure_signature); two tier downgrades with explicit re-promotion path declared. * README.md, BASELINE.md, CLAUDE.md — invariant count synced 94 → 95 across every load-bearing surface. * .claude/commit_acceptors/falsifier-final-cluster.yaml — diff-bound acceptor with inverse-probe falsifier: exits 0 (i.e. invariant broken) ONLY when check_claims.py re-emits the WARN(v3) line about missing falsifier-blocks. Catches any future regression that re-opens the floating set. What this does NOT do --------------------- * Does NOT modify any code under research/, core/neuro/, or any test file the falsifiers cite. Acceptor `forbidden_paths` excludes all of them. The tests already exist on main; this PR only adds governance metadata pointing at them. * Does NOT promise the codebase is "complete". The ANCHORED ladder discipline is closed; new ANCHORED claims will require new falsifier-blocks. The two EXTRAPOLATED downgrades carry explicit re-promotion paths. * Does NOT close Q5 / Q7 IERD frontend work, Phase-4 EXIT for Q6, or any subsystem deployment. Those are tracked as separate issues with their own acceptance criteria.

All five hpc-* ANCHORED claims gain v3 falsifier-blocks. Three new invariants (INV-HPC3 ledger_conservation, INV-HPC4 state_envelope_integrity, INV-HPC5 session_fsm_totality) added with peer-reviewed references and resolving source/tests/integration_test paths.
Falsifier coverage: 9/21 → 14/21 ANCHORED.
Floating list: 12 → 7.
