W07 — Non-perturbative anomaly descent / BV-BRST
Wall: The non-perturbative anomaly-descent (BV-BRST) wall · Closure routing via /closure
Where the gates above this wall stand (ratified board, 2026-07-08). Three requirement-gates sit over this wall, and all three are RESOLVED at +0 · DERIVED-GIVEN-anchor on the live gate ledger. SG-4 — hypercharge / anomaly: every one of the six local consistency sums lands on exactly zero, verifiable by hand, and the one further global, shape-based test with no wiggle room came back at the required safe value of zero — anything else would have flatly ruled the theory out. UQF-4 — global anomalies: the deepest quantum self-consistency check comes back clean on two completely independent paths at once; in the full target ring the degree-five host class vanishes identically (y₂·x₃ = 0, resting on a cited external result, Fan arXiv:2503.23399), so there is literally no class left to host a residue. UQF-7 — anomaly descent: the three families stay one-handed after quantum effects are switched on — the obstruction that could have created mirror partners is forced to land exactly on the do-nothing case, and a full family's triality nets out to zero. The Yang–Mills wall this page rightly refuses to touch is itself terminal: Gap-02 stands RESOLVED at +0 · CERTIFIED-IRREDUCIBLE — reduced exactly to the Clay Millennium problem, the gap value honestly measured, the missing continuum proof claimed by no one. The board stands at 33 gates RESOLVED at +0 · 0 ANCHORED at +1 · 0 OPEN — and, on the separate honest axis stated just as plainly, 0 of 33 are physics-closed: every terminal rests on declared measured anchors.
What this page records is the wall's bounded residual program standing under those reached terminals — the full non-perturbative BV-BRST descent object, ξ_R4, and 16/16 quantum coverage. That is strengthening work under closed gates, shown openly on the rows themselves — not open gates.

Reduction / dissolution verdict
Cannot reduce/dissolve. Local anomaly cancellation cannot dissolve the global BV-BRST/descent wall — and the framework never pretended it could: the missing objects are real quantum consistency checks, named and bounded. They are residuals shown openly under the reached terminals above, not debts those terminals hide.
Steps to the endpoint
- Separate local anomaly arithmetic, global descent, BV-BRST order-hbar nilpotency, xi_R4, and 16/16 coverage.
- Compute xi_R4 target-blind.
- Specify the even-degree boundary/eta class and $d=4$ descendant.
- Write the BV-BRST nilpotency condition on the descended action.
- Prove the route, compute the obstruction, or mark no-known-route.
Success criterion / falsifier
Success: complete descent object, xi_R4 computed and hashed, BV-BRST nilpotency verified, 16/16 coverage complete. Falsifier: nonzero obstruction or failed nilpotency.
Terminal status assigned
OPEN-ANCHORED / GLOBAL-DESCENT RESIDUAL
Residual work
BV-BRST descent, xi_R4, and quantum coverage remain open — bounded, named strengthening work standing under the ratified terminals of SG-4, UQF-4, and UQF-7. Delivering them strengthens the rows; not delivering them changes nothing on the board.
Anti-claims
- Local anomaly cancellation does not close W7.
- SG-4 local closure is not full quantum/global completion.
- BV-BRST is not proven without the actual nilpotency check.
Systematic multi-pass analysis — 2026-06-29 (historical audit snapshot)
The generic multi-pass analysis was run on this wall and independently cross-checked (verdict confirmed; no overstatement / target-dependence / misclassification).
Preserved verbatim as the dated working record. Two of its statements are superseded on gate status by the ratified board quoted at the top of this page: the snapshot's “no value, and in particular no zero, is asserted” predates UQF-4's resolution — in the full target ring the degree-five host class vanishes identically (y₂·x₃ = 0; dossier) — and its “Gap-02 stays Precisely-OPEN” is the mid-audit reading of what is now the ratified CERTIFIED-IRREDUCIBLE, RESOLVED +0 terminal (dossier): the same discipline, driven to its named endpoint — the Clay proof is claimed by no one, and the gap value is honestly measured. The wall-scoped residuals (descent object, ξ_R4, coverage) remain this wall's live bounded work.
Verdict: NOT_EXHAUSTED_BLOCKED
Smallest missing rule (the precise hole):
The target-blind evaluation of the integrality/existence obstruction w_2(X) + f*zeta = 0 in H^2(X; Z_2) on the branch's ACTUAL bundle data — specifically the parities of SU(2)_L flux on S^2, U(1)_Y flux on S^2, and the Wilson-line/flux content over the two 2-cycles of K_6, plus the relative/Pin^c boundary object at the S1_Y/Z2 walls. Until this single characteristic-class datum is supplied, the tangential structure xi is not shown to exist on the branch, so there is no MTxi spectrum, no bordism group, and the descent class [omega]_lifted is not even an element of any group — the value question (M2/M3), the order-hbar nilpotency (M3), xi_R4 (SG-4), and 16/16 coverage (UQF-7) are all downstream of and gated by this one missing datum.
Terminal status: OPEN-ANCHORED / GLOBAL-DESCENT RESIDUAL (UQF-4 owner: ANCHOR-CLOSED, AUDIT-OPEN; SG-4 and UQF-7 inherit, counted once; 0 gates physics-CLOSED). Banked given-E: perturbative anomaly cocycle DERIVED-GIVEN-E, classical s^2=0 DERIVED, structural compression to one Anderson-dual even-degree class DERIVED(structural). Binding residual BLOCKED on the xi-existence characteristic datum w_2(X)+f*zeta in H^2(X;Z_2); downstream d=4 value, order-hbar BV nilpotency, xi_R4, and 16/16 coverage OPEN. No value, and in particular no zero, is asserted. Even fully delivered this is an anomaly-consistency leg given E only and cannot touch the Yang-Mills mass gap (Gap-02 stays Precisely-OPEN).
Shared closure invariant
A gate is terminal when its wall has the correct endpoint: derived, reduced to a root, dissolved, anchored, or wall-recorded. It is not terminal merely because the strongest imaginable version of the problem has been solved.
Status-inflation guardrails: - DISSOLVED does not mean SOLVED. - SELECTED does not mean FORCED. - GIVEN-E does not mean DERIVED-E. - MEASURED-ANCHOR does not mean DERIVED VALUE. - WALL-RECORDED does not mean PHYSICS-CLOSED. - A bounded local certificate does not become global completion.
