Restore handbook regeneration to its maintained receipt - #832

Scope

Restore the handbook test's live publication binding so a later profile or handbook regeneration updates its own maintained receipt, instead of editing #826's dated landing record.

• Base commit: 6d252c9c102e575bc9229bf6bb2149409655d5f3; head: 4d2ce2a7719adca918025ffde295ef1dfa30bf02.
• Lane: lane:foundation; draft.
• Exactly four paths: tests/test_new_wsl_handbook.py (one receipt-path line), evidence/artifacts/new-wsl-handbook-20261001/receipt.json (current computed binding plus one appended regeneration), its one-line README.md, and registry last.
• The generator, profile, both generated outputs, hash/inventory assertions, existing receipt observations/history and Enforce dated model currency and propose daily source reviews #826's dated record stay byte-identical.
• Named landing path: co-op cross-family exact-head read, hosted validate, command center CI read and cue; right after Consolidate catalog evidence, organic controls and foundation records #820, ahead of feat: combine native Lanes collector and dashboard monitoring #775. ONE replay at that cue if Consolidate catalog evidence, organic controls and foundation records #820 changes main; full test phase in that landing turn. Hold this draft head for the reads.

SOTA sources

• native-agent-stack@6d252c9c102e575bc9229bf6bb2149409655d5f3:tests/test_new_wsl_handbook.py:1672-1691: the publication contract checks actual current generator/profile/output hashes and inventory, with byte-change negative controls. Its comment says hashes follow regeneration. Only its receipt locator changes.
• Same pin, evidence/artifacts/new-wsl-handbook-20261001/receipt.json:268,656,700: the receipt is a current hash mirror and prior entries expressly refresh mutable producer/output bindings while preserving observations. This existing repository practice fills the publication-binding gap; no new manifest, generator or validator is introduced.
• Same pin, docs/acceptance-evidence-policy.md:59-65 and docs/landscape-domain-notes.md:33,38: retain historical inputs/results/failures/pins. All prior receipt fields, regeneration prefix and previous_outputs are retained; Enforce dated model currency and propose daily source reviews #826's dated record remains historical.
• Same pin, docs/lanes.md:94-115: main-copy/own-registration protocol; scripts/host_receipts.py:710 updates the three own hashes and inserts the README, in the registry-only final commit.

Local commands run

All checks use the owned external TMPDIR, nice -n 19 ionice -c3 and closed stdin.

python3 -B scripts/build_new_wsl_handbook.py --check
exit 0, status passed; current outputs unchanged.
python3 -B -m unittest tests.test_new_wsl_handbook
exit 0: Ran 87 tests in 37.368s; OK.
Exact unchanged-field, regeneration-prefix, dated-record and one-test-line comparison
exit 0; all preservation controls true.
python3 -B scripts/validate.py
exit 0 before and after final registry commit; 10508 file hashes.
git diff --check
exit 0.

The scoped cached open-PR check found 44 open PRs and these overlapping neighbours: #645, #754, #769, #770, #810 on the maintained receipt; #776 and #810 on the test. The CC assigned this narrow critical-path repair before later regeneration PRs. No peer head or file is edited by this lane.

Decision record

The CC's J-HANDBOOK-BINDING ruling supplies the bounded disposition. The one-line receipt README identifies the maintained current-state carrier. No old decision or dated observation is rewritten, and no extra decision file is added to this small unit.

Host evidence

No host/client/installation or acceptance-status changes. These checks establish the repository publication contract, not upstream model or native host acceptance.

Landing read fields

The intentional main-test edit is tests/test_new_wsl_handbook.py:1677, disposed of in advance by the CC for this exact receipt rebind. Name it in main-tests= at the landing read. Declare every actual post-read/replay change in adapted=; the full-suite phase is deferred to the landing turn. Nothing is re-pointed to a new dated path.

Checklist

• Existing current-state receipt reused; earlier observations and dated record preserved.
• Only one test line changes; assertions, producer and profile unchanged.
• Own entries registered last; required local checks pass.
• No workflow, dependency, paid surface or credential change.
• Draft and one foundation label; named read/ACK/queue path.
