Date: 2026-09-21 Scope: Cross-feature correction and integrity audit only. Context Drone V1 remains engineering-validation pending.

Result

SOURCE-AWARE PARALLEL ACCESS IMPLEMENTED AND VERIFIED for the source-path and isolation scope below. This does not qualify Context Drone behavioral performance.

Change

Context now receives explicit, immutable SourceView objects for FOUNDATION, MEMORY, and each drone's context_self state. Source gates are use_foundation, use_memory, and use_self_context; omitted gates preserve legacy self-context behavior. Each source is normalized independently and fused only in temporary forward-pass work state. Provenance is exposed in last_source_reads and telemetry. Foundation and Memory views are detached clones, and the structural-v1 memory query still derives directly from the original byte-token input before context fusion.

Processing sequence

embedding -> Foundation transformer blocks -> read-only Foundation view -> structural-v1 Memory query/retrieval and memory residual -> read-only Memory view -> selected Context Drone source reads (independent normalization) -> bounded context residual -> final RMSNorm -> lm_head.

Memory and context artifacts remain separate. Context reads do not mutate drone state; memory reads do not mutate the context fabric.

Shared-path inventory

Source access and isolation checks

The source matrix is available at runtime through the three independent gates. Focused tests verify self-only compatibility, Foundation-only access, and explicit Foundation+Memory view enumeration. Reads leave drone versions/checksums unchanged. The Memory structural-v1 address is unchanged when Context is enabled because it is derived from tokens, not fused hidden state.

The current Context implementation is not a semantic answer decoder, so Foundation-only/Memory-only source-answer tasks are recorded as latent source-path checks rather than a behavioral qualification claim. Conflict resolution is intentionally undefined; source provenance remains visible.

Regression and verification

• Focused Memory/Context/source tests: 9 passed.
• Complete backend suite in [retained internal evidence]: 109 passed, 2 environment deprecation warnings.
• Foundation and promoted adaptive units were not trained or serialized by this change.
• Context serialization remains independent of Memory serialization.
• Disabled Context clears last_reads; disabled Memory clears retrieval telemetry (carried from the preceding integrity correction).

Artifact evidence

Machine-readable evidence is in [retained internal evidence]. No model binaries or feature artifacts were created. Context behavioral qualification and Dynamic Routing remain out of scope.

Conclusion

Source-aware access is implemented and verified at the execution-path, provenance, feature-gating, and state-isolation level. No cross-feature state mutation was detected in the tested scope. A future Context behavioral qualification must still establish semantic task performance independently.
