Change and purpose

Adds one document, docs/ELDER_EVENT_TETHER_20261031.md. It answers the first item of the owner's 31 October assessment: connect the abstract selection estimate back to the actual measurable elder-rule pair event. Scope: mathematics, statement-level only.

• The gap. PairLawInterface.p in the Lifetime spec (Math- f2508f7f) is a free number. Its own docstring says nothing ties it to the field or to the elder relation. Math-GB-8g: D1-D2 lifetime/remainder retro bindings (12 unbound, NOT A RESULT) #543's constant-one inhabitant makes that consequence formal. Theorems B and C consume the actual ElderPartner relation; Theorem A does not. Nothing formal links the two ends.
• The proposal. Five tether conditions, T1–T5, that would make p = E_Q[W e]/Z with e the actual elder indicator, plus an UNCOMPILED Lean shape for discussion.
• The one substantive observation. Tying p to e is not enough. If Q is any law with the right pins, a Dirac mass at a cap-type function gives p ≡ 1, which is the GB-8g: D1-D2 lifetime/remainder retro bindings (12 unbound, NOT A RESULT) #543 inhabitant again. So the indispensable condition is T2: Q must be the field's canonical whole-field regression law (display (12) of PERSISTENCE_BRIDGE.md §4.1). Under T2, display (16) of that file (if its proof holds) makes p ≡ 1 impossible, which is the natural negative control for any future formal tether.
• The inventory. For each condition, the existing Math- artifacts at 19a55750 with blob ids: C291 field realization, the C263 Field adapter, C292, test: detect stale active-board routing against AGENTS #487, the finite-dimensional gaussianRegression_hasCondDistrib, and the d=2 endpoint kernel sourcePhysicalEndpointKernel_eventually_hasCondDistrib. The whole-field regression kernel and the measurability of e have no Lean predecessor. They are the first two formalization targets, in that order.

Second commit: retroactive source resolution (1b2e00a4)

Adds docs/retro/RETRO_SOURCE_RESOLUTION_01CZ_20261031.{md,json} and a read-only, standard-library resolver.

• What it checks. It covers the 126 coverage-ledger units marked has_source = false. For each one, it asks whether the unit holds mathematical text, and whether every declared {path, git_blob} source resolves to exact bytes.
• Text. 105 of the 126 units hold their own mathematical text. The flag mostly reflects a filename heuristic.
• References. Of 520 declared references, 484 resolve at main, 29 resolve in path history, and 7 are unresolved.
• Six of the seven are on the elder-rule chain. frontiers/window_multiplicity_laws_20260928 (the source of the E4 elder lower bound) declares an algebra.py (blob 00140088) whose publication the tool blocked, plus five evidence files. None of them is in any Git branch, Drive or Dropbox search.
• The ledger is not edited.

Third commit: exact successor check of the elder lower-bound algebra (af55f878)

Adds experiments/elder_lower_algebra_successor_20261031/, a standard-library Fraction checker with a README and CLI-invoked negative controls.

• Why. The direct lower bound 1 − p_r ≥ c r³ (Theorem E1) rests on finite algebra whose original algebra.py is unrecoverable from the repositories.
• What it checks. An independent re-derivation of (E3), (E5)–(E7), the pin Hessians, the extra-saddle height −7/32, the overlap integral 3/10 and the Beta(2/3, 2) moments.
• Controls. Six mutants are each rejected on their intended check.
• Limits. It checks no probabilistic step of E1, and it is not a copy of the blocked file.

Fourth commit: binding proposals for unbound graph nodes (db4eb7e6, plus a record correction)

• Twelve bindings. 12 of the 16 unbound graph nodes in the docs: RETRO-MATH-BIND-01 retro math inventory + all-bot binding assignments (NOT A RESULT) #527 binding report match their GRAPH.json fingerprints to exact file bytes at Math- 19a55750.
• Checker. The repository's tools/graph_binding_check.py exits 0 on the 12 and exits 1 with one sha256 corrupted.
• Four left unbound. A register flag, a status-row stand-in and two label tokens have no byte identity, so they are left unbound on purpose.
• Correction. The seventh unresolved reference (REV-P15-B.md) is a documented prize-track exclusion, not a gap.
• Nothing is edited in the graph, the binding report or the hypergraph.

Fifth commit: the field-valued regression kernel in Lean (8aacf47e)

Adds experiments/whole_field_regression_kernel_20261101/, a standalone Lean package pinned to Lean 4.34.1 and Mathlib d13f23b7 (the Math- pins). It is step 1 of the tether's §7, and condition T2 in structural form.

• The kernel. The finite-dimensional regression kernel is generalized to a residual field T → ℝ (product σ-algebra). The kernel is specified at every pin value, including probability-zero pins.
• Conditional law. Under pin/residual independence, R + mY + c (X − mX) has that kernel as its conditional law given the pins.
• Independence. Independence from every finite restriction of the field implies independence from the whole field, through the measurable-cylinder π-system.

Checks (run_checks.sh, outputs in evidence/):

• lake build succeeds.
• leanchecker replay passes, and the missing-module control fails.
• The axiom audit shows 8 theorems, standard axioms only, and a sorry control is detected.
• The three negative controls fail to compile, as they must: a wrong sign, a dropped independence hypothesis, and single-coordinate to whole-field independence.

The local build compiled Mathlib from source, because the prebuilt cache host is blocked by this session's network policy. Hosted CI does not build this package.

Still open:

• The actual Gaussian field's independence beyond Fin k coordinates.
• A smooth-function Borel σ-algebra.
• Continuity of the kernel in the pins.
• T1, T3 and T4.

Current disposition

• Head and integration owner: the head is this branch. Integration goes through whoever holds the main lock; I will not merge or mark Ready.
• Claim / handoff: none.
• Completed review scopes: none.
• Unresolved finding IDs and next action: a different-family mathematical read is requested (xAI or OpenAI), focused on whether §4's remark is right, and whether T2 is really weaker than every alternative that excludes the GB-8g: D1-D2 lifetime/remainder retro bindings (12 unbound, NOT A RESULT) #543 inhabitant.
• The branch carries a history-preserving merge (94a3ed24) whose tree is exactly main 4712fc13. Only the one new file differs from main.

Verification

• python3 tools/workspace_landing_check.py: problems: [].
• python3 -B -S tests/test_research_delivery.py: OK.
• python3 -m unittest discover -s tests -p test_workspace_landing.py: OK.
• python3 tools/navigation_check.py: exit 0.
• git diff --stat origin/main HEAD: 9 new files plus the Lean package; the tether doc is also updated.
• python3 -I experiments/elder_lower_algebra_successor_20261031/check_elder_lower_algebra.py: OK. python3 -m unittest -v test_check_elder_lower_algebra and its -O run: 3 tests OK in each mode. The six --mutate runs each exit 1 on their intended check.
• The resolver was run at Math- 19a55750 and main 4712fc13. The totals check out: 105 + 20 + 1 = 126 units and 484 + 29 + 7 = 520 references.
• Every quoted Lean statement and docstring was read from the Math- blob named beside it. The artifact search was a git grep over *.lean outside inputs/, and it may miss differently named work.

Evidence and limits

• It proves no theorem; the §4 remark is conditional on one cap-type function existing.
• It compiles nothing.
• It reviews or accepts none of the sources it cites.
• It establishes no rate, coefficient or parameter range.
• It assigns no status.
• Authorship: Anthropic/Claude (session 01CZ) for Dylan Roy. Organizational-independence credit 0; no human review.
