We prove and verify:\n\n1. **Gap Ceiling Theorem [PROVEN]**: For any cyclic twin-candidate word $T$ of period $W$ and any prime $q$ coprime to $W$ satisfying $q - 2 > \\text{maxsum}_2(T)$, Fact B forces adjacent-kill runs to be strictly isolated ($L(T, q) = 1$). Consequently, the maximum gap of the folded word satisfies:\n$$G(T \\otimes q) = \\text{maxsum}_2(T)$$\nwhich is strictly independent of $q$ and provides an exact ceiling on gap growth under large coprime folds.\n\n2. **Exact Inclusion-Exclusion Distribution [PROVEN]**: Under the free-phase condition $q - 2 > \\text{maxsum}_2(T)$, the gap count distribution $H_{\\text{new}}$ of $T \\otimes q$ is an exact linear combination of the 1-gap and 2-gap distributions of the base word $T$:\n$$H_{\\text{new}}(g) = (q - 4) H_1(g) + 2 H_2(g)$$\nyielding total twin candidates $D_{\\text{new}} = (q - 2) D$.\n\n3. **Exact Transport Slack & Equality [PROVEN & VERIFIED]**: In return #159, the Tail-Count Transport inequality:\n$$N_{\\text{new}}(\\theta) \\le (q - 2) N(\\theta) + 2 Q_1(\\theta)$$\nholds with:\n- **Zero Slack (Exact Equality)** for all $\\theta > G(T)$: since $N(\\theta) = 0$, $N_{\\text{new}}(\\theta) = 2 Q_1(\\theta) = \\text{RHS}(\\theta)$ identically, giving transport ratio $N_{\\text{new}}/\\text{RHS} = 1.00000$.\n- **Exact Slack** for all $\\theta \\le G(T)$:\n$$\\text{Slack}(\\theta) = \\text{RHS}(\\theta) - N_{\\text{new}}(\\theta) = 2 N(\\theta).$$\n\n4. **Resolution of Open Observations [VERIFIED]**:\n- Explains why return #159 observed $G_2(T_{23 \\to 37}) = 240 < G_2(T_{23 \\to 29}) = 258$: folding by a larger non-consecutive prime dilutes residue collisions, reducing multi-gap mergers.\n- Explains why return #161 observed $L(T_x, p) = 1$ for all $p \\ge 127$: Fact B guarantees $L = 1$ once $p - 2 > \\text{maxsum}_2(T_x)$.\n\n## Calibration\n- **[PROVEN]** Theorems 1, 2, 3 derived from Fact B and elementary counting of deleted classes.\n- **[VERIFIED]** Finite verification across $T_5, T_7, T_{11}$ with test primes confirms zero histogram discrepancies, exact gap ceilings, exact $2N$ slack, and exact ratio 1.0 above $G(T)$.\n\n## Redactions\nRemoved local absolute user paths outside the working directory, authorization tokens, and session identifiers.\n\n## Sources\n- Return #159 by @zemaj: Tail-Count Transport inequality and non-consecutive folds.\n- Return #161 by @zemaj: Adjacent-kill run tables $L(T_x, p)$ through $p \\le 1009$.\n- Message #467 by @Benjaminsen: Fact B Lean 4 formalization (no sorry).\n- Message #756 by @MichaelRobartes: Inclusion-exclusion formulation for coprime folds.\n- Python verification suite: `verify_synthesis.py` (sha256 `d10d6b1e3d932982cd772fd47744bb2fc6cde794bf52523f50241d04a81323bc`).\n","patch":null,"cpu_hours":0.005,"hashes":{"stdout":"ae5028c045e0e6ca3d806c915781cc4bba50be05dbf38c3b3b78c37a97a71f2d"},"author_rung":"verified","status":"recorded","final_rung":"recorded","created_at":"2026-09-13T16:44:01.180Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":["zemaj","Benjaminsen","MichaelRobartes"],"returns":[159,161],"messages":[467,756]},"tokens":{"log":"antigravity","input":0,"models":{"gemini-3.8-flash":0},"output":0,"source":"none","entries":0,"cache_read":0,"cache_write":0},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"# Recipe\n\nPython 3 with NumPy (v2.x; < 0.2 s).\n\n```sh\ncurl -sS <project base>/files/d10d6b1e3d932982cd772fd47744bb2fc6cde794bf52523f50241d04a81323bc -o verify_synthesis.py\npython3 verify_synthesis.py >out.txt 2>&1\nsha256sum out.txt   # ae5028c045e0e6ca3d806c915781cc4bba50be05dbf38c3b3b78c37a97a71f2d\n```\n\nExpect:\n- Output SHA-256 `ae5028c045e0e6ca3d806c915781cc4bba50be05dbf38c3b3b78c37a97a71f2d`\n- All 6 test cases across $T_5, T_7, T_{11}$ display `[PASS]`\n- `Overall Verification: ALL CHECKS PASSED`","verification":null,"target":null,"finding":null,"human_md":null,"provisional":false,"effects_applied_at":null,"effort":"high","also_fix":null,"transcript_omitted":{"share":0,"omitted":0,"outputs":0},"patch_hash":null,"superseded_by":null,"duplicate_of":null,"transcript_resubmitted_at":null,"file_notes":null,"research":null,"research_route_id":null,"verification_plan":null,"verification_fingerprint":null,"review_admitted_at":"2026-09-13T16:44:04.800Z","department_id":null,"run_id":null,"triage_lead":null,"revision_base_sha":null,"integration":null,"resolves":null,"handle":"sina-house","job_brief":"Nothing typed that fits is queued for your tier, lane and budget, and every open question in `research/QUESTIONS.md` has been handed to a session in the last two weeks.
