Change and mathematical scope

Exhaust all 523 old unmarked BIT terminal arrivals in two exact source scopes. The endpoint allows at most 12 independent marked returns with literal live peers and 14 when free historical coframed quiet caching is granted. The fixed moonshot target requires 21. The quiet raw net upper is −1.4176039760312882. Even granting perfect new donors, one separate positive-rank split per additional donor leaves raw net upper −0.35408633858153143 at target and −0.5869197763976802 at the stricter trial. NO VERIFIED GAIN. κ change is exactly 0%.

Task and overlap

Canonical e545235, revision 8. The bit-helper-contract card changes to aggregate terminal source stock on the exact selected BIT word. #7258 at 90a63fb holds all 523 unmarked terminal payloads fixed. This result lets them change within exact old coframed source libraries. It preserves the marked libraries, complete terminal span, terminal paid types and all upstream paid payloads. It also prices a separate split relaxation and records the exact shared-transport threshold.

#7209 at 77feabf supplies the marked bank geometry and price. #7244 scientific head 4156504 independently anchors the complete comparable κ = 0.003645372367832.

Validation

From the checkout root with CPython 3.12 and assertions enabled:

python3.12 -B scripts/research_package.py --package research/bit-terminal-donor-stock
python3.12 -B scripts/check_research_commit.py --package research/bit-terminal-donor-stock --check-modes --check-source-history

The offline replay authenticates six public source paths and regenerates both the fixed-payload receipt and the full 5,448,489-byte donor receipt from literal inputs. The independent audit reconstructs all source libraries, endpoint quotient matches and ten exact tariff cases. A forged quiet stock of 15, altered source byte and duplicate manifest path were rejected. The clean 3.12.14 replay, all 27 committed byte/mode/source-history checks and six navigation tests passed. Exact fractions, source hashes and receipt digests are in the package. No changed native supplier, materialized multiplier or selected cold replay ran.

The branch reuses the existing navigation prerequisite f2206e6 in a separate commit for hosted planning. Hosted checks are pending at opening.

Credit

Credit Jerry Chen / CubeJerry #7001 and #6726 for the BIT word, ToikY #7209 for the bank classes and tariff, #7258 for the joint terminal quotient proof, and Clear1nsight #7244 for the comparable complete witness. OpenAI Codex and subagents materially assisted. Exact notices and public source pins accompany the package.

Open next questions

The next gate in NEXT.md indexes 185 existing rank-at-least-two paid ports. The target needs t+s ≥ 9 and at least two additional independently useful slots on funded paths in the optimistic cost model. Alternatively, expand the marked prebirth libraries while preserving the paid word. Either route needs an exact joint endpoint, clock, ownership and restoration proof.
