Shay e84c0e8428 feat(deduction-serve): Band v6-EX — existential witnesses, decided (ADR-0261)
Completes the all/no/some square. `some` is read for the first time:
"All mammals are vertebrates. Some whales are mammals. Therefore some
whales are vertebrates." is decided entailed; "All unicorns are horned.
Therefore some unicorns are horned." is decided unsettled, with the
no-existential-import reading disclosed in the surface.

Mechanism (generate/proof_chain/exist.py): v5-VP's per-individual
lowering over a domain widened by one Skolem witness per existential
premise and — the load-bearing part — one ARBITRARY element per
existential conclusion, at which every universal still instantiates and
about which no premise asserts anything. Refuting an existential means
deriving a universal, and the arbitrary element is what makes that
derivation genuine instead of an assumption of domain closure: without
it "Rex is a wolf. Rex is not tame. Therefore some wolves are tame."
reads as REFUTED from a domain of one wolf. With it, UNKNOWN.

Four `en_exist_*` bands earned SERVE at 720x wrong=0 on the first arena
seal (25-band ledger); the 32-case hand-authored v2_exist split passed
32/32 first run; full lane 166/166 wrong=0 across six splits.

Also fixes a wrong-answer path this work uncovered in Band v1b
(ADR-0261 §5.1): `to_syllogism` FILTERED premises it could not express
out of the projection and answered from the remainder, so "Aristotle is
a philosopher. All philosophers are scholars. Therefore some scholars
are philosophers." lost its only witness and was served "that doesn't
follow". It now refuses — matching its propositional sibling
`to_deductive_logic`, which always has — and the argument falls through
to the bands that can hold a singular fact. The categorical band
re-earned SERVE 720/720 after the change; both examples are pinned as
regression cases.

Promotion: `ds-mem-0020` declined -> unknown (ADR-0258's existential
scope-out, now read; an anonymous witness never transfers to a named
individual, so UNKNOWN is its honest verdict, not entailed).

[Verification]: core test --suite deductive 232 passed; reader tests
33/33; register+surface tests 52 passed; arena 25 bands x 720 wrong=0
(all SERVE); lane 166/166 wrong=0; lane SHAs 9/10 match (public_demo
drift is pre-existing on the base commit and unrelated — evidence in
the Tier-S brief).

CLAIMS

Every row below is mechanically derived from in-tree state and verified by CI. Tier 1 rows come from core.capability.ledger_report; Tier 2 rows come from scripts/verify_lane_shas.py's pinned SHAs.

Tier 1 — Ratified domains

Each row asserts: the domain's packs pass all nine ADR-0091 contract predicates, declared operator chains meet the ≥8 / ≥3-intent floor, the reviewer registry resolves the primary reviewer, and the ledger status predicate evaluates to reasoning-capable with no open gaps.

Domain Status ADR Packs Open gaps
philosophy_theology reasoning-capable ADR-0085 2 0
mathematics_logic audit-passed ADR-0097 1 0
physics audit-passed ADR-0100 1 0
systems_software audit-passed ADR-0101 1 0
hebrew_greek_textual_reasoning reasoning-capable ADR-0102 4 0

Tier 2 — Pinned lane reports

Each row asserts: running the lane's runner produces a JSON report whose SHA-256 matches the pinned value below. Mismatch is a CI failure (.github/workflows/lane-shas.yml).
