+# LAB E37 — RAVNOVES00 acceptance contract R0
+
+## Result identity
+
+Status: `accepted-r0-source-scoped-contract`.
+
+Result:
+`e37-ravnoves-acceptance-01b1efd586f747341c712d82f0907b39436a6f91ae92b1dfae987eca05fd8344`.
+
+Worker package:
+`e37-worker-package-960b804df639dd2937895377aa67d5dca4b325f293ab48868d16049da2ff28bc`.
+
+Physical execution node: `DESKTOP-OPJ8J04` / Worker 006.
+
+## Question
+
+E37 does not ask whether K1 has already reached 90% quality. It asks which
+immutable RAVNOVES00 cases, task ontology, split and metrics will be used to
+make that claim honestly in the next gate.
+
+The prior E30 evidence review supplied a useful engineering-reviewed
+substrate, but it was not yet an acceptance contract. Without freezing the
+denominator and validation holdout, later tuning could silently move the
+evaluation set or collapse presence, point ownership and freshness into one
+ambiguous score.
+
+## Frozen source and provenance
+
+Source recording:
+
+- display name: `RAVNOVES00`;
+- session: `20260720T065719Z_viewer_live`;
+- classification: immutable private physical recording.
+
+Inputs:
+
+- E30 materialization:
+  `e30-materialization-841af926d8d28ab93538c46d8f31278a2234c4d1c12c7dc4dc296b249d59735a`;
+- E30 engineering generation:
+  `e30-engineering-generation-62a4fea10dea9b77f69ceac1af5bf0e4928d9c7716083c22258a03670fe5bd4f`;
+- E30 human exception generation:
+  `e30-review-generation-7982a882558d0be690b4c7092e328c080bfcbf52478a220452be7e887a588250`.
+
+The result binds the exact manifest and decision-file SHA-256 values for all
+three inputs. Of 486 terminal labels, 484 come from the accepted engineering
+generation and two from the saved user exception decisions. These labels are
+not described as independent ground truth.
+
+## Method
+
+Profile: `e37-ravnoves00-r0-acceptance/v1`.
+
+The deterministic builder:
+
+1. verifies the exact E30 identities and artifact digests;
+2. requires one engineering decision for every materialized review item;
+3. requires human decisions to match the declared exception set exactly;
+4. projects each reviewed item into three independent dimensions:
+   presence, geometry association and freshness;
+5. assigns severity without changing the reviewed outcome;
+6. creates a deterministic 30% validation holdout inside each source-stratum
+   and range bucket using seed `ravnoves00-r0-validation-v1`;
+7. closes terminal accounting and rejects any free-space claim;
+8. publishes four immutable artifacts atomically.
+
+The worker package contains only the runtime projection, profile and the six
+required input manifest/data files. Execution used the pinned Triton image
+with no network, a read-only container filesystem, dropped capabilities,
+`no-new-privileges`, a bounded PID limit and no GPU allocation.
+
+## Contract
+
+| Measure | Result |
+| --- | ---: |
+| reviewed items | 486 |
+| development items | 340 |
+| validation items | 146 |
+| terminal outcomes | 486 |
+| accounting | 100% |
+| engineering-reviewed labels | 484 |
+| human exception labels | 2 |
+| false-free claims | 0 |
+
+Frozen distributions:
+
+- presence: 300 `object-present`, 104 `occupied-environment`,
+  82 `background-or-noise`;
+- geometry association: 108 `object-associated`,
+  104 `independent-occupied`, 100 `insufficient-support`,
+  92 `unknown`, 82 `rejected-nonobject`;
+- freshness: 292 `current`, 102 `unavailable`, 92 `stale`;
+- severity: 290 `standard`, 71 `medium`, 125 `high`.
+
+The following targets are declared separately for R1 and later gates:
+
+- presence quality: at least 90%;
+- geometry-association quality: at least 90%;
+- freshness quality: at least 90%;
+- accounting: 100%;
+- false-free claims: zero.
+
+## Acceptance
+
+All seven predeclared R0 checks pass:
+
+- source identity is frozen;
+- reviewed denominator is complete;
+- development and validation split is complete;
+- every item has a terminal label in all three dimensions;
+- human exception accounting is complete;
+- false-free claims are zero;
+- authority remains diagnostic.
+
+## What this proves
+
+RAVNOVES00 now has one reproducible source-scoped evaluation contract. Future
+algorithm changes can use the 340-item development set without changing the
+146-item validation holdout, label ontology or denominator. Presence,
+geometry association and freshness can no longer be reported as one blended
+success score.
+
+## What this does not prove
+
+E37 does not evaluate or pass any 90% quality target. It does not provide
+independent ground truth, prove another route, camera, rig or mount, validate
+free space, or grant navigation, command or safety authority.
+
+## Decision
+
+Accept R0 as the only RAVNOVES00 measurement basis. The next planned K1
+laboratory gate is R1: compute the first source-scoped perception-quality
+baseline on the frozen validation holdout, diagnose the separate deficits and
+tune only against the development partition.
