flang/proof/binary-fingerprint.fscript writes bootstrap/flang.seed-sha256 and, with -- --forgery, runs the four probes on a copy of bootstrap/. corpus-share.sh loses its fingerprint modes; the build command, CI and the provenance hint call the plan.

flang/proof/kernel-verdict.fscript asks the kernel about every source a record of the tree names, against a ledger built from a commit or given as a file. kernel-verdict-forgery.fscript is its probe: a lie committed with its record passes the share ledger and is refused here. corpus-share.sh loses both modes; its self-test calls the probe plan.

flang/proof/records-nesting.fscript prints every corpus record again with the kernel of the tree and compares it byte for byte, after the same seed freshness test as before; it takes -- --root for the self-test. share-ledger-forgery.fscript is the ledger probe. Both modes leave corpus-share.sh; CI, the short commands and the docs call the plans.

The ledger probe, the seed fingerprint probe and the corpus nesting check now get FLANG_TMP from the runner like the other steps; their plans default to /srv/tmp, which the runner does not have. The plans now say which variable to set when no temporary directory is made.
