Change and mathematical scope

Implement and preserve a bounded configured-prefix source verifier. It accepts the exact authenticated original prefix rendering with only eight top-level gate literal values replaced by independently pinned plain data. Nongate bytes must match exactly. The pure checks cover UTF8 byte offsets, exact types, duplicate gates, inert expressions and bounds; accepted gate DATA is not an admission.

A separately reviewed constructor successor changes only the native environment literal from a bytes-key dictionary to six immutable bytes pairs. Every constructor function body remains byte-identical and dict(NATIVE_ENV) returns the same six-entry mapping. The tuple is compatible with the original closure literal parser without a mutable exemption. Future policy must select constructor v2; the old v1 remains an inert comparison.

The exact frozen core hashes are 1ed813148c10d5fbd3cd6781d51eca650a347eda7a6323f581d740e6ea9cb6e2 (verifier) and a80a60b390bc60e9bc434b79cda5ae6db88e4f0c6c7436de9adfe1f48a2045b1 (constructor v2). The package has 29 files, 173,055 raw bytes and 18 copied-origin records. This is a completed narrow pure-source increment; full C05 and full V03 remain open.

Task and overlap

Canonical base 7c49fe32c55de02c2c873655c804b16e4c3fef0a. This follows #6362's pure prefix/fixture/observer work at 120072d58ddb46f0e02886756243174d41fce42e, #6363's actual parent/interface audit at a8cf650b7435ccea237084e491e339f725c0a35b, and #6367's finite-cover source constraints at 234a650277d286f2ebec104eb65ce9456f80667c. It closes the specific configured-source-derivation and bytes-key literal capture edges. A separate conditional supervision contribution retains real-owner/bootstrap/interval dependencies.

TASK.json records the explicitly changed publication subtask relative to the historical portable-replay card, with the original scientific objective and denominators preserved. The named overlap is bounded; no novelty or global exhaustive-search claim. This result adds no original activity credit: original 43.5%, 22/49 activities, stage 2/10, milestones 1/10, 24 components and 52 helpers are unchanged.

Validation

Standard-library Python 3.12, repository root:

python3 -B scripts/research_package.py --package research/h25-v03-configured-prefix-derivation --check-only
python3 -B scripts/research_package.py --package research/h25-v03-configured-prefix-derivation

Local metadata/pins, registered preservation checks and eight new pure fixture methods passed in normal and optimized modes. A final-manifest-bound package-only cold copy passed both profiles; outputs are outside the packet and all final package bytes remained identical. The adapter only rebinds fixture IMPL/ORIGINAL paths. Core, fixture, assertions and algorithms are unchanged. Committed-byte/mode/declared-history preflight passed for all 29 files; the exact added-only remote tree and parent match local. Actual hosted results will be reported after completion at the published head.

Original variant and closure source, older constructor and pre-repair verifier are inert .py.txt evidence. No original function/module, receiver capture, Root, Popen, native control, compiler, namespace or target workload runs. Static source compatibility is not actual receiver-policy/module-identity/48-module closure fit. All None gates, pre-repair evidence and source-window timing gaps remain visible. No private Pro transcript is exported; documentary hash references are external context, not live replay inputs. Git provenance covers declared base/card inputs, not complete original source history.

The app goal is separately paused. Current guarded attempt approval remains false; old recorded policy debit 94.550533479/2400 seconds is not complete physical cost. Preparation, review, publication and other physical costs remain OPEN_NOT_ZERO.

Preserve all source authors/notices, PR6321/6029/5864, unpaidmoon/Cursor Grok PR6339 and Douglas R. Colkitt's lineage. New code is Apache-2.0. AI review and finite fixture results are distinct from human/proof-kernel acceptance.

Open next questions

Bind actual complete receiver-policy identities using constructor v2, an authenticated fresh pre-import parent bootstrap and the unchanged closure limits. Complete the C05 determinant inventory, actual cap/physical-cost bill and lifetime channel mechanism, C07 instance, original independent admissions, full intact baseline and named V03 controls. This contribution grants no runtime capability, new budget, merge or frontier adoption.

Delivery verified at exact head 3a2d75adec6133a5bc3e6c4a082369101e6c1158: attempt1 hosted plan and actual registered replay completed SUCCESS, including unchanged committed inputs. Canonical handoff records the 8 new pure methods per normal / optimized profile, exact source/export review, byte provenance, reproduction, attribution and original C05/V03 boundaries. The adjacent conditional supervisor is #6369, head 190e63e0ca5b16e45d8202bec7dc7426dc76c5dd. This draft remains unmerged; no original activity credit, target execution or actual admission follows.
