RESEARCH QUESTION (plane continua / prime ends and BFMOT variation; SS-COF (the side-selection half of DP-K after strip normalisation, Route I): can a canonical KP strip near the outchannel theta_F have failing doors (full trace K_s = X) at cofinal depth, when every index/variation count is blind to them?). Self-contained. Label every claim PROVED (you prove it), SOURCE (exact reference; unchecked?), LAB (from this prompt, status as given), CONJECTURE, OPEN, or RESTATEMENT (a gap reworded). If a definition is ambiguous, state your reading in one line and continue. Say where your argument stops. A. DEFINITIONS Setting (compressed from the lab lanes b_opus_dpk_ne, b_opus_ssdyn and codex_sscof, all single-agent, UNAUDITED except where a status says otherwise). - X is a nondegenerate nonseparating plane continuum, U := C \ X, h: X -> X a homeomorphism with h^2 continuum-minimal (cm: no nonempty proper subcontinuum K with h^2(K) inside K) and m_1 := min_x d(x, h x) > 0 (an R-instance). F, G are perfect plane extensions of h and h^-1 (G is NOT F^-1 off X). Each of F, G has a unique outchannel E_F, E_G (prime ends of U with principal set X); assume E_F != E_G. - A crosscut s is an open arc in U whose closure is an arc with distinct ends in X; Sh(s) is the bounded component of C \ (X u s). K_s := the smallest subcontinuum of X containing both ends of s (EB1: K_s = X iff X is irreducible between the ends). A door s is M_F (resp. M_G) if Sh(s) misses a tail of the external ray of E_F (resp. E_G); a door FAILS if it is M_F and M_G and K_s = X. - A canonical KP strip near theta_F: a nested chain of KP-chords (sides are Kuratowski-Pelczynski chords plus points of X) defining E_F; its doors are its chords; depth n means the n-th chord. SS-COF: there is n_0 with no failing door of depth >= n_0. FT (strong form): every crosscut q with diam q <= m_1/8 that is M_F and M_G has K_q != X. - codex_sscof (GPT family, OPEN-OBSTRUCTION, UNAUDITED): beyond a finite depth every canonical door is nonessential for the channels of F, G and F^2, and its three variations are zero (conditional on the KP laws). For a fixed failing KP door s, expose s outside an arbitrarily fine full KP auxiliary Jordan disk Y_d; its boundary splits into a pocket-side arc A_d and an opposite arc B_d; then A_d -> X in the Hausdorff metric, all sufficiently fine KP component chords of A_d have variation zero, and the variations on B_d sum to -1. The enclosing curve is s u B_d; the other loop s u A_d bounds an exterior lens with no X inside. So full trace does not change the KP enclosing-curve budget. B. LEMMAS (status; where used) Known (statuses as given; single agents). - b_opus_ssdyn (Claude Opus, PARTIAL, UNAUDITED): (1) Prop NX: if the image-end crosscut C of the failing configuration exists, the F-variation law var(F, s) = 0 at a small M_F door s (with C as the short image path) gives s not in Sh(C): the shadows of s and C are disjoint (order (D)); order (N) is impossible. (2) Pair calculus: for a small crosscut q with ends a, b, var(F, q) depends only on the image pair (h a, h b) and the position of q; if X is irreducible between a and b, any two short crosscuts joining a and b are homotopic in U u {a, b} (Lemma UJ; one free-API check disputes UJ as stated). (3) Prop DEG: deg(F, Sh(q), w) equals that locally constant function; in a failing configuration F maps the M_F pocket D = Sh(s) with degree +-1 over the far part of the E_F pocket Sh(C), and G maps Sh(C) with degree +-1 over the far part of D. Prop HOM: if F were a plane homeomorphism this is a contradiction; for perfect extensions F(s) may meet X, so it stops. (4) Theorem R: literal DP-K over normalised abstract strips is equivalent to FT; if FT fails the failing configuration is realised with ALL dynamic laws (F, G, m_1, unique outchannels, cm, CP1, DO-all, DO-var, EB, UNIQ): the first violated clause is FT itself. (5) FT implies IMP3: no prime end other than E_F, E_G has impression X. IMP3 implies FT is OPEN. The downstream users quantify over cofinal depth, so SS-COF (weaker than FT) is the honest target. - Cross-family audits: R-KP-W / U3 (every small KP-chord has var(F^2) in {-1, 0}, = -1 if it crosses the channel essentially): CONFIRMED-WITH-REPAIRS (Claude Sonnet audit of a GPT proof). NX, pair calculus, conditional DEG, HOM and FT => IMP3 survive a GPT-family audit; Theorem R has a closed-strip gluing gap. - DP-K (cofinal) <=> SS-COF under the strip normalisation (codex_dpk_consolidate, PARTIAL, conditional on A-START and a landing-access input). C. THE TARGET SS-COF as defined above: no failing door at cofinal depth of a canonical KP strip near theta_F. D. ASK Part 1 (diagnosis). Explain in your own words why every variation/index count is zero at deep doors and why full trace K_s = X is invisible to the KP enclosing-curve budget (the pocket arc A_d tends to X with zero chord variations; the opposite arc carries -1). Decide whether ANY additive integer invariant of crosscuts (variation, degree, intersection number with a ray) can see K_s = X; prove a no-go or give one. Part 2 (non-variation invariant). Attack SS-COF with ONE of: (a) prime ends of the pockets Sh(s_n) for cofinal failing doors s_n: show they produce a third prime end with impression X (contradicting IMP3); (b) cm of h^2 applied to a Hausdorff limit of the sets cl Sh(s_n) cap X or of h^2-images of pockets; (c) the degree transport DEG between the M_F pocket and an E_F pocket, iterated along the strip. State which you use, and carry it as far as it goes. Part 3 (builder). Try to build cofinal failing doors in a canonical strip: a nested chain s_n of KP-chords with ends a_n, b_n such that X is irreducible between a_n and b_n for every n, all doors M_F and M_G, consistent with E_F != E_G unique outchannels and cm. Record the first law your data violates, or report consistency with the exact list of laws checked. Each claim labelled PROVED, SOURCE (exact reference), LAB, DERIVED, CONJECTURE, OPEN or RESTATEMENT. UNKNOWN if unsure a cited result exists. E. CONTROLS (all must hold) (C1) Knaster-type control: in the bucket-handle continuum, X is irreducible between many pairs of points; your Part 2 argument must not exclude full-trace crosscuts in a setting with no h (say which hypothesis of an R-instance it uses at which line). (C2) Finite depth: an argument that excludes failing doors only at depth <= n for each n, with a threshold depending on n, does not prove SS-COF. (C3) The transplant of Prop TR produces a failing door at bounded depth only; it is not a counterexample to SS-COF. F. DEAD ENDS (not progress) (1) Index budget / KP enclosing curves at deep doors (codex_sscof: all zero). (2) Second geometric G-outchannel inside the pocket and proper h^2-invariant J from the configuration alone (b_opus_ssdyn Props 5.1, 5.2). (3) Channel membership / hyperspace laws: side-blind (Prop SB). (4) Literal NE over abstract strips (Prop TR). RESTATEMENT GATE (mandatory; answered BEFORE the headline, in its own section). If your verdict reduces the node N to a residual lemma L (with or without other proved pieces), you must give ALL of: (G1) the exact statement of L and of N side by side, with the same standing hypotheses; (G2) a proof that L implies N (the reduction); (G3) a reason L is STRICTLY weaker than N: either an explicit configuration (or consistent abstract data meeting every standing law) where L holds and the conclusion of N is not yet available, or the named hypothesis of L that the negation of N does NOT supply; (G4) the line of your argument where L's own hypothesis (the defect, the witness, the scale) is actually used; if it is never used, L is a restatement. If G3 or G4 fails, the headline word is RESTATEMENT, not REDUCED, and the answer reports the proved building blocks only. A headline REDUCED without G1-G4 counts as a failed answer. G. FORMAT Line 1 exactly: VERDICT: SS-COF PROVED (no failing door beyond some depth of a canonical KP strip; proof with a named non-variation invariant) | COFINAL FAILURE CONSISTENT (explicit data: cofinal failing doors meeting every listed law; first missing global law named) | REDUCED (to one named lemma, gate G1-G4 passed) | PARTIAL (one named sub-claim settled) | OPEN. Then SUMMARY (<= 100 words), the argument (<= 2,000 words), STILL OPEN EXACTLY. Short of effort: line 1 + summary; an honest OPEN is valid. No finite computation as proof; no theorem beyond its hypotheses; UNKNOWN if unsure a cited result exists. RED FLAGS: using a variation or index count to see a full-trace door (they are all zero at deep doors: codex_sscof section 3); using the transplant of Prop TR at cofinal depth (its band is compact); assuming F is a plane homeomorphism (Prop HOM uses that; perfect extensions may send s into X); treating finite depth for every n as one cofinal configuration; claiming DP-K, L2 or PER
