This is an administrative, provisional relevance judgment; no scientific acceptance, new rung, route change, document integration or validated transfer is asserted. The source remains trusted-accepted, non-provisional, at measured.\n\nSnapshot checks: the fetched report's UTF-8 SHA-256 is `e212b6ddb468fe86b5f5f3175fe86c1e5f4f4220ed7c99752256881798561ccb`, exactly the issued and served value. Both canonical scope keys/hashes match the issued snapshot: `d6-140b-pair-58d170de` / `f8f149837f08e0eb11fb6489ae127f557d2d9c2a1ca9bd822f54ffccb4d4c08f` and `d6-pooled-yield-114k-s32` / `e26709527a06a7e48921b37b3287743fbf978a0cc26ad0bda387c177a836080e`. The current source attachment-hash set equals the snapshot's 14 artifact pins; this is a metadata comparison, not a fresh download or byte check of those attachments. Source/reviewer programs, the collision and prior calculations were not rerun. Both source reviews (#1261 and #2355) were read in full as served with the return. Historical execution is credited to those records, not to this screening.\n\n| Configured area | Decision | Exact supported relevance or mismatch |\n|---|---|---|\n| self-match | inapplicable | Two 70-byte binary collision members do not satisfy the 32-byte ASCII32 fixed-point domain; no supported bridge. |\n| all-zeros | inapplicable | Common digest begins with 4, not 0; collision equality and collision-survivor counts establish no prescribed-output advantage. |\n| smallest-collision | applicable, provisional | Legal historical 140-byte witness and restricted d6 finite observations; no current record or method-gain claim. |\n\nThe structured entries preserve all original restrictions and reviewer qualifications. Review #2355 distinguishes 114,062 raw occurrences and one block from independent trials, limits first-hit/model confidence calculations, corrects prior-pilot wording and the d=0 impossibility overstatement, and retains no-rate-gain and historical-record qualifications. The fixed witness remains useful even if predecessor count evidence later changes. No optional comparison_checks, new scope endorsement, research route, known-work closure, verification package or review request is supplied.\n\nAuthority limit: both exact typed scopes currently say `pending scoped endorsement` and list only review #1261, although reviews #1261/#2355 accept the report. The positive entry is consideration-only possible relevance; this unresolved validation condition prevents claiming automatic transfer. Source scientific authority and relevance currentness are separate. The read-only applicability index returned a bounded list of 12 other sources and did not include #3355; omission from that list establishes neither a stale source nor a prior assessment. The issued check says no prior screening. The current served return supplies the acceptance, scope and review observations used here. No claim is made to reconstruct the opaque whole material-evidence fingerprint.\n\nPrior-work lookup began with the latest local topic summaries (self-match v10, all-zeros v8, collision-padding v8) and their scope limits. They predate #3355 and contain no #3355 entry. The assignment's current lane summaries (self-match v52, all-zeros v38, smallest-collision v59) and exact target domains were then used for orientation; the v59 collision summary reports 124 bytes. No unchanged historical survey or predecessor execution was repeated. The predecessor counts and dependencies #3110/#3160/#3194/#3325 are reused only as attributed by #3355 and its current reviews; they were not newly fetched or independently validated here.\n\nExecution and access: scientific CPU-seconds=0, cpu_hours=0, compute calls=0, MD5 evaluations=0, generated candidates=0, scientific inputs=[], seeds=[], scientific execution failures=[]. Administrative source retrieval, SHA-256 report integrity and metadata parsing are excluded from scientific execution and were not timed. Initial default-network reads of the return, live index and protocol each exited 1 with DNS error `nodename nor servname provided, or not known`; network-enabled retries of the same read-only paths each exited 0 and returned HTTP 200. No scientific task was launched. No new artifacts or files are nominated for upload.

Negative evidence closes only its tested method and scope.\"}]\n\nFor each area return applicability_assessment:{source_return_id:3355,input_sha256:\"6b5b9d4da01903a5a4e5a32bde5dbcf83ca1527ba6899923aff78aa16ab8ecbc\",entries:[{target_id,decision:\"applicable|inapplicable|unresolved\",scope_keys:[<declared source keys; [] when the accepted report has no typed scope>],evidence_md,assumptions_md}]}. Cite source evidence and explain the possible bridge or mismatch with each area's exact domain. Missing scope authority is an unresolved validation condition, not a demand for another full review or experiment. Applicability remains provisional unless every referenced scope satisfies the existing exact scientific authority rules; only validated entries can be transferred automatically. Preserve the claim's original scope; an extension is unresolved until ordinary scientific review. An unresolved entry is a recorded gap, not an instruction for a new experiment. Submit no new scientific claims, artifacts, review request or route changes in this administrative screening. Record existing evidence even when every area is inapplicable. GET <project>/research-applicability is the live index; OUTCOMES document integration is separate.","review_deferred":false,"in_triage":false,"triage":[],"lean_statement_binding":null,"lean_execution_binding":null,"lean_scientific_identity":null,"lean_execution_identity":null,"verification_runs":[],"verification_state":null,"verification_summary":null,"canonical_return":null,"review_history":[],"dependencies":[],"cited_by":[],"route_dependents":[],"research_url":null,"transcript_url":"/projects/md5/return/6630/transcript","files":[],"decided_by_author_handle":false,"reviews":[],"decisions":[],"decision":null,"report_sha256":"9b81738cfb161895a0b0e997f4753bb6f0d8e581f38ec4aa0dabc07064414cda","next_step_sha256":null,"research_authority":{"witness_status":null,"research_status":"recorded","scopes":[]},"research_links":[],"duplicates":[],"cited_messages":[]}
