From 6bb344a44513c0ab456bd73e7a8d1e3babaa46fa Mon Sep 17 00:00:00 2001 From: Max Ghenis Date: Wed, 2 Sep 2026 09:24:28 -0400 Subject: [PATCH 01/61] Interface amendments 11-13: entrants, mass partition, declared tolerance - decl.py: Node.entrants (EXPAND only; cannot conserve mass) and Graph.mass_partition (an (entity, column) every CREATE node declares with a partition dtype; normative, folded into structural node keys). - kernel.py: Tolerance(rtol, atol, ulps); Capabilities.tolerance is required for tolerance_bound kernels and forbidden for bitwise ones; KernelContext.tolerances hands readers their inputs' owners' bounds. - serialize.py and keys.py carry the new fields; older JSON still loads. - fit.qrf@1 declares a provisional Tolerance(rtol=1e-6) pending measurement across arm64 and x86_64. - Charter: amendments 11-13, D2 clarified (weighted person mass per stratum; composition-changing expansions declare), rows B6, C5, D6. - Lock re-recorded; B2's KernelContext field pin gains tolerances. Max ruled go on the two dynamics decisions (microcosm-dynamics#412); the B6/C5/D6 acceptance tests follow from the acceptance lane.

let the ratchet admit a property new to the charter The acceptance lane (sol, 20260902-092431-acceptance-11-13) added the three strict-xfail tests and the toy machinery they need: a toy EXPAND kernel with declared entrants, a tolerance-bound producer and a gate that reads context.tolerances, and a partitioned toy source. Each fails today at the absent feature, not before it (evidence in the lane report). tools/graph_acceptance_burndown.py now treats a marker on a property the baseline charter never listed as a new red rather than a re-red, with a unit test for both directions.

B6: an EXPAND node with entrants=True accepts null lineage; entrant rows are built from the kernel's materialized columns (every carried column required, dtype-checked), memberships must name incumbent or entrant groups, the lineage receipt records [new_id, null], and cached replay restores the null. Entrant persons stay fail-closed for now: KernelResult has no channel for their stratum (amendment 14 follows). - C5: capabilities.tolerance is recorded in every receipt, resolved for every declared input into KernelContext.tolerances (rewrites read the incumbent's owner), bound into the producer's key so a changed tolerance invalidates readers, and carried through manifest save/load. - D6: mass is accounted per (partition, stratum) when Graph.mass_partition is set; conserve is enforced per partition and names the partition value; the receipt carries a nested partition block beside the flat fields; kernel-declared accounting is validated to the same shape. - fit.qrf@1: the H1 fixture regenerated on arm64 and on x86_64 under Rosetta differs by zero cells, so the declared bound is Tolerance(ulps=1) with the measurement in the constant's comment; only pins.json moved. Suite: 207 passed, 0 xfailed; H1-H3 byte-exact; burndown total 0.

Max Ghenis Date: Wed, 2 Sep 2026 12:19:16 -0400 Subject: [PATCH 05/61] Amendment 14: entrant persons carry their stratum (charter B7, red) Implementing amendment 11 showed the frozen KernelResult had no channel for a new person's mandatory stratum, so entrant persons were fail-closed while immigrant cohorts are persons. KernelResult.strata (EXPAND kernels on an entrants=True node) names every entrant person's stratum by id; the executor requires exactly the entrant persons there. Charter row B7 is committed red with a toy kernel that admits one entrant person into an incumbent household; it fails today at the executor's null-lineage refusal. Lock re-recorded; suite pins count 45 properties, 4 red.

An entrants=True EXPAND that adds person rows supplies KernelResult.strata for exactly the null-lineage person targets; missing entrants, incumbent or copied ids, unknown, duplicate or null ids, a mismatched id dtype, or strata outside that context reject the named node. Copied persons inherit their source stratum; entrant persons take their declared label, which may introduce a new stratum; membership materialization keeps them in total and per-stratum mass. Cached replay attests the full person stratum vector against an ordered receipt["entrant_strata"] of [person_id, label] pairs (bytes labels in a tagged hex form). The sanctioned flip removed only B7's marker; suite pins report 45 properties, zero red. Verified here: 252 tests across the graph shard, kernel packages, and both country graph suites; ruff; partition and burndown verifiers.

15:08:53 -0400 Subject: [PATCH 09/61] Address the #851 review: seven rulings, each with its regression test Built by a sol lane (20260902-134618-fix-851, one commit per finding, squashed here without its journals) and verified independently: 262 tests across the graph shard, kernel packages, and both country graph suites; ruff; burndown total 0 against origin/main. - EXPAND overlays may not name an entity's id column; final id indexes are asserted against lineage cold and warm. - An entrant's partition value is structural: the EXPAND overlay supplies it with no downstream claimant, while ordinary nodes still cannot own the partition coordinate (composed entrant-with-partition test). - Cache identity binds the full canonical Capabilities projection, not tolerance alone; a cache load misses when the stored capabilities disagree; PARAM- and EXECUTOR-seeded fit.qrf no longer share entries; tolerance stays outside implementation_hash; signed zeros key identically. - KernelContext.tolerances covers rewrite incumbents, resolved against the input version as the compiler and keys do. - Entrant materialization bridge claims require ROWS_ALL. - RunManifest.population() returns one documented PopulationView type; no __class__ mutation. - fit.qrf's tolerance comment states the provisional one-ULP budget honestly; pins regenerated. A bogus partition receipt block is rejected on unpartitioned graphs.

496ce95c5db777095dfd75687d0bc3843c7b05e4 Mon Sep 17 00:00:00 2001 From: Max Ghenis Date: Wed, 2 Sep 2026 21:52:03 -0400 Subject: [PATCH 10/61] Address the #847 gate review: partition ownership, tolerance propagation, ratchet identities, B7 copies Sol's gate review of #847 (six findings). The two high findings on the manifest round trip and Capabilities in node identity were already implemented on #851, so that branch is folded into this one (merge 1e95b526) and #851 closes as superseded. The rest: - compile_graph refuses any non-CREATE owner of the mass-partition column, rewrite or not: a partition value is fixed when the row is created, because a reassignment with the total unchanged is invisible to every mass policy (D6 case; the executor's runtime guard stays as defense in depth). decl.py re-locked. - KernelContext.tolerances resolves through structural carriers to the node that produced the values, so a bitwise FILTER neither tightens nor erases a producer's bound, and a rewrite sees the incumbent producer's (C5 carrier case; charter C5 wording and amendment 13 updated). - The acceptance ratchet compares property identities against the baseline, not per-file counts: a property green there and red now is a re-red whatever else went green and whichever file the marker sits in, a marker on an id the charter does not list is refused, and new files are counted. Three unit tests cover the offset, new-file, and invented id paths; git ls-tree is given a directory because it takes no globs. - B7 now also refuses a stratum label for a copied person (labels_copied mode on the toy entrant kernel).

The constant's comment says what would justify tightening it; the H1 pins follow the identity (finding 8). - Tolerance normalises rtol/atol to representable finite floats at construction, so an integer too large for a float fails there instead of at identity time (finding 9). - Charter C5 gains the loosest-writer rule for coordinates written by more than one node (entrant materialisation, claims); the executor side of that rule, the schema-v1 manifest migration, copy validation, the D2 receipt for every population change, the per-partition ledger in the explorer, and PopulationView.entity() follow in the next commits (findings 2, 3, 4, 5, 7, 10).

only module-level tests count, with unit tests for each form. - Every schema-v1 manifest receipt is legacy in full; a v1 receipt that carries a tolerance or the v2 legacy flag is refused as a hybrid. - Amendment 15: entity, column, and row-mask names are dot-free, so the entity.column spelling in receipts and evidence is unambiguous (lock re-recorded). - Amendment 16: Numeric.PLATFORM_BITWISE. Measuring fit.qrf@1 natively on arm64 against x86_64 under Rosetta (tools/graph_qrf_platform_probe.py, docs/graph-qrf-cross-platform.md) found 45 of 6,000 drawn cells moving by up to 7% because a one-ulp difference flips the donor a quantile draw lands on, so no per-cell tolerance is true of it. The kernel declares platform-bitwise numerics and no tolerance; H1 pins regenerated.

From cff82d7bb04638ed392aa0fe33bbe63990d3623c Mon Sep 17 00:00:00 2001 From: Max Ghenis Date: Thu, 3 Sep 2026 08:08:16 -0400 Subject: [PATCH 25/61] Address the fresh #847 gate's round 2: platform-scoped keys, a fail-closed ratchet, dot-free names everywhere, a view that does not intercept - A platform-bitwise kernel's node key carries a platform fingerprint (architecture, OS, Python minor), so a shared store never serves another platform's output; other kernels' keys are unchanged. Parity pins record the platform and numeric class; H1 asserts bytes on the pinned platform and identity partitioning elsewhere. - The ratchet's suppression scan fails closed: an alias for pytest, a 'from pytest import ...', a parametrize over a non-literal, or a pytest.param carrying marks anywhere in the module is refused rather than resolved (tests for each form). - Amendment 15 covers every naming channel: WeightTransition.entity and Graph.mass_partition at declaration, and a CREATE kernel's returned Frame at run time (lock re-recorded). - PopulationView no longer overrides __getattribute__; a colliding entity name resolves to the Frame member as on a Frame, entity() stays the accessor, and inherited Frame operations keep working on the view.

This lane journal lives - under `docs/graph-847-r5/` to comply with the explicit root-journal boundary. -- Read `docs/graph-acceptance.md`, including amendments 11--17 and the - interface freeze; `docs/graph-interface.lock`; all seven named graph modules; - the acceptance burndown tool; both named fit modules; and the H-parity test. -- Confirmed amendment 17's `NumericScope` interface already exists in frozen - `kernel.py`, while executor context construction still supplies only the old - tolerance projection. -- Reproduced finding 3 with five red parametrized cases: annotated - `pytestmark`, an assigned skip alias, and all three `unittest.skip*` - decorators returned no suppression problem. The scanner now rejects every - decorator on a collected test that it cannot prove is an allowed direct - pytest mark. Adversarial follow-up cases also reproduced nested, - destructured, named-expression, attribute/subscript, and dynamic-namespace - `pytestmark` bindings; dynamic suppressor aliases; counterfeit pytest roots; - and mutation of the trusted `pytest.mark` root. The scanner now fails closed - on each of those unresolved forms, refuses aliases of the `pytest` object, - including aliases smuggled through parametrization cases, restricts its - non-marker use to direct non-suppressing assertion helpers, and - conservatively inspects deferred bodies for bindings and aliases. The - complete burndown-tool unit file, actual ratchet verification, and focused - Ruff pass. -- Reproduced finding 5 through the graph store: `POPULACE_FIT_N_JOBS=1` and - `=2` produced the same node/artifact identities but pickle bytes differed at - byte 798. `_Forest` now serializes a shallow model copy with canonical - `n_jobs=1`, leaves the live fitted model untouched, and restores the current - runtime setting on trusted unpickle. The cache-collision regression and all - fit-kernel tests pass. -- Reproduced finding 2 by changing only an authenticated body seed from integer - `1` to float `1.0` and recomputing the serialized key; schema-v2 loading did - not raise. Current-body validation now compares canonical bytes per receipt - and tier, and also requires the accepted serialized key to equal the rebuilt - manifest key. The full manifest unit file passes. -- Reproduced finding 9 with a 400-digit schema-v2 tolerance integer; - `RunManifest.load` leaked `OverflowError: int too large to convert to float`. - The parser now passes validated numeric values into `Tolerance` unchanged so - its existing normalization raises `ValueError`, which the loader wraps as - `StoreCorruptError`. The full manifest unit file remains green. -- Reproduced finding 1 from a real signed certified graph manifest: deleting - only top-level decisions preserved its key/body and `load_certified` still - returned certified. Release receipts now authenticate the normative required - decision names, and certified loading rederives the outcome from those names - and the carried signed records. Missing requirements fail closed; missing - records report `unreached`. A final adversarial pass also reproduced five - carried-record substitutions with blank legacy/current signature fields; - all retained the authenticated body/key and were accepted. Certified load - now revalidates the exact signed-record shapes and every required field as - non-empty. Focused executor, full manifest, and acceptance F-gate tests pass. -- Reproduced finding 10 by removing portable mass evidence from a calibration - receipt while retaining an attached partitioned `MassRecord`; totals rendered - but the partition heading and row were absent. The fallback now uses the - canonical `mass_record_receipt` projection, preserving every partition field. - All graph-explanation tests pass. -- Reproduced finding 8 with three cached EXPAND corruptions: an incumbent cell - changed, an undeclared column added, and a declared new column removed. All - three replayed without error. Cached restoration now requires the exact base - plus declared column set for every entity, validates declared dtypes, and - compares every incumbent column's complete prefix with storage semantics - before checking copied additions. The focused regressions and full population - unit file pass. -- Reproduced finding 7 with a dotted `expand_cells` column: the cold execution - did not raise and authored provenance the warm parser cannot represent. - Entity and column names are now required to be dot-free by the shared EXPAND - parser, executor receipt-coordinate discovery uses that parser, and an - all-node preflight refuses malformed declarations before source hashing, - keys, cache I/O, or kernels. Both cold/auto regression variants pass without - creating store objects. The combined executor/population run passes apart - from the known QRF fixture pin made stale by finding 5 and due for finding 6. -- Reproduced finding 4 with an integrated gate over all-bitwise, sole - platform-bitwise, and mixed bounded/platform coordinates in both mixed-writer - orders: the gate received an empty `numerics` mapping and failed. Executor - aggregation now applies the explicit bitwise < platform-bitwise < bounded - order, combines bounded tolerances componentwise, retains the current - platform whenever any writer is platform-bitwise, and derives `tolerances` - from those exact scopes. The tolerance-reporting gate also records numeric - class/platform and returns `evidence_absent` for an explicitly different - comparison platform. Focused tests, kernel contracts, executor tests (apart - from the pending QRF parity pin), and acceptance C all pass. -- Reproduced finding 6 by forcing the H1 simulate case down its off-platform - branch: the test completed with zero byte comparisons and no identity - assertion. H1 pins now include the target node key; the graph source is the - stable `inputs.csv` file rather than the self-referential fixture directory. - H1 asserts key inequality off-platform and key equality plus bytes on the - pinned platform, without counting a skipped byte comparison as evidence. - Fixtures were regenerated after the tool was formatted, and the H1, - serialization, QRF cache-collision, seed-source, and implementation-pin - regressions pass. A forced off-platform fit case also passes with zero byte - comparisons after asserting the key partition. -- The first required full Ruff invocation exposed a pre-existing import-order - defect in the amendment-17 root export block. The import names were reordered - without changing exports or behavior; verification restarts from the first - required command after this committed cleanup. -- A final read-only adversarial audit found that mutating - `sys.modules[__name__].__dict__` through `update` or `setdefault` could still - install an imported `pytestmark` without a scanner finding. Both variants - reproduced as empty suppression results. Nonliteral/current-module - `sys.modules` access now fails closed while the acceptance suite's existing - literal `_toy` loader remains allowed; the focused parametrized regressions - and actual burndown verification pass. -- The same audit found direct and imported `unittest.SkipTest` runtime raises - were honored by pytest but produced empty suppression results. The scanner - now rejects the public and `unittest.case` runtime spellings plus every - direct-import alias, including raising the exception class without calling - it; all three new regression cases pass. -- The first full required graph-plus-fit run reached 100% with one failure: - frozen acceptance B still asserts the pre-amendment-17 `KernelContext` field - set and omits the already-locked `numerics` field. The same contradiction is - present at the pinned starting SHA; the prohibited test and frozen kernel - remain unchanged while the remaining audit and rerun proceed. -- The complete required verification block was rerun after the final hardening. - Ruff lint passed, Ruff reported all 52 files formatted, the acceptance - burndown reported 41 green/0 red/0 missing with `verification=ok`, and CI - grouping reported 354 tracked test files with `verification=ok`. The exact - required pytest command exited 1 after collecting 432 cases: 429 passed, 2 - skipped, and only the unchanged acceptance-B field-set assertion failed. - -## Next - -- Reconcile the frozen acceptance-B assertion with amendment 17 under explicit - authority to edit that test. No permitted implementation change can make its - eight-field expectation and the locked nine-field `KernelContext` contract - true simultaneously. diff --git a/docs/graph-847-r5/out.md b/docs/graph-847-r5/out.md deleted file mode 100644 index 5804ccd7f..000000000 --- a/docs/graph-847-r5/out.md +++ /dev/null @@ -1,301 +0,0 @@ -# PR #847 gate round 4 report - -Starting SHA: `cdbf71888f4b5896e124519d643fa2347c483123` -Starting merge base with `origin/main`: `6022e4f5c8af31d62fddd1c7dbd1ab9eea81b0f6` -Local lane branch: `fix-847-r5` - -All commands below were run with `uv run`.
