Status: NOT QUALIFIED — STOP FOR REVIEW Date: 2026-09-23 Scope: Query-conditioned addressing within the manually selected C1 Context Drone.

Starting point and recovery

The previous native Context candidate had demonstrated Direct Context Transfer at 505/512 (98.63%), while Context Binding was 396/512 (77.34%). The failed full candidate had been deleted. This corrective run reconstructed the direct-transfer-qualified U3 continuation once from the immutable Foundation 001.x parent and the recorded training protocol.

The reconstructed U3 candidate reached 500/512 (97.66%) on sealed direct transfer. Its causal rerun scored 98.44% with Context enabled, and 0% original-answer accuracy with Context disabled, absent, or wrong. The bounded Foundation screen was 160/160; the qualified parent baseline was 159/160. The parent checkpoint SHA-256 remained [checksum retained in the private evidence record].

The active U3 candidate SHA-256 was [checksum retained in the private evidence record] (52,265,546 bytes). Its base tensor hash before Address Block training was [checksum retained in the private evidence record].

Diagnosis and design tested

The remaining behavior is within-C1 addressing: select the value associated with the requested key. The Address Block was kept separate from the manual C1 Context Router, Shared Context Encoder, Native Context Access layers, Memory, and Foundation. It emitted start and end scores over Context token positions; expected values and span labels were used only by training and evaluation.

The first variant used one final Foundation query state, token-level Context Encoder outputs, two projected pointer scorers, and address dimension 160. It had 154,882 parameters. Its developmental Stage A exact-span accuracy was 21.88% after 1,000 steps. A bounded query-representation correction then supplied the full frozen Foundation query-token sequence with a learned query-token weighting. This second variant had 155,522 parameters. No Foundation, Context Encoder, AdaptiveWeightUnit, or Memory parameters were trainable during either address run.

The procedural curriculum required counterfactual queries: every training Context contained multiple key/value pairs, and each key in that unchanged Context was queried in turn. Keys and values were generated separately; validation and sealed keys and values were reserved before training and excluded from training. Field order was shuffled and target positions varied. Training advanced A (two fields), B (three), C (four), and D (four plus distractors) only when the held-out stage reached 97% exact-span accuracy.

Span labels were calculated in the final byte-token sequence from the assembled Context string. The target token span decoded exactly to the expected value in all 80/80 explicit label-integrity checks. The qualification generator produced 1,000 sealed queries across 250 counterfactual Context groups. Its dataset hash is recorded in the machine-readable evidence.

Results

The developmental results show query-insensitive selection: start and end accuracy remained at 50% on two-field Stage A, with half of predicted starts in the wrong requested field's record. The token-sequence query variant did not fix the failure. The sealed result confirms the failure boundary, but the architecture decision was based on the developmental split; the sealed set was not used to choose training duration or tune either variant.

The first attempt stopped at step 200 because its generator incorrectly demanded globally unique one-to-two-character keys and exhausted the finite Stage A key space. That generator defect was corrected; training then reused keys and values across training groups while retaining disjoint held-out identities. The corrected run completed Stage A and still failed its developmental gate. The initial failure, corrected variant, and their lightweight metrics are preserved separately.

Integrity and blocked work

Address training changed only the Address Block candidate parameters. The U3 candidate tensor hash was identical before and after Address Block training. The immutable Foundation checkpoint stayed byte-identical. The 41 U3 Foundation tensors had changed only during the explicitly authorized U3 reconstruction; the recorded mutation set contains no out-of-scope parameters. The manual router stayed fixed to C1. Memory and AdaptiveWeightUnits were not attached or mutated; the prior cross-feature integrity record lists the memory interface/store checksums and notes that promoted units are remote artifacts.

The independent address threshold of 99% was not reached. Therefore the Address Block was not connected to the Native Context Access path. Final binding integration, Address-on/off and wrong-query causal ablations, oracle-address diagnostics, and fresh-process Address Block restore were not run. The previous 77.34% binding result remains the last completed binding measurement. Structural generalization and all multi-drone, Global Context, movement, and routing work remain unstarted.

No Address Block binary was promoted or retained. The temporary 52,265,546-byte U3 continuation checkpoint remains at its active-candidate path because the system's automatic review blocked its deletion, even though the directive's cleanup policy calls for removing a failed continuation. Its checksum is preserved in the evidence; the immutable Foundation parent remains in place.

Disposition

CONTEXT ADDRESS BLOCK V1 NOT QUALIFIED — STOP FOR REVIEW.

The direct Context transfer path remains demonstrated. The unresolved failure is query-conditioned key matching and span selection from frozen query and Context representations. Addressing did not qualify, so no final binding behavior can be claimed and no further roadmap feature was started.
