Changes touching this path

• loot apply-patch refuses a patch that deletes a path and also renames it away: refuse_shared_paths now counts every path a stanza removes, as a deletion or as a rename old path, and refuses both rows, where the run used to move the file, remove the old path once and discard the second NotFound, and a row it refuses that was already refused keeps its first reason with the shared one appended. a rename old path that another stanza writes stays allowed, as #1995 pins, and ADR 0082 says why and where git apply differs; the rename writer now reports every removal error. the offer_cost double counts account_of, and the two constant-cost cases pin it at the one read Reader::new makes since #1955. the apply_strict comment and ADR 0082 no longer say an unmarked kept last line claims nothing: format-patch writes one when only the new side ends with a newline, so it stays unchecked, and a hunk that adds no line loses that newline. plan_one shares one helper for the rename and add verdicts, the ClassReads, ingest_cost and offer_cost doubles and Reader::new have docs true to the code, no shared base double is added since the conformance double delegates every method, and the CONTEXT.md, ADR 0077 and ADR 0082 rewrap leftovers are fixed. before the change the new rename test went red (12 passed, 1 failed), as it did with deletions uncounted, with the deletion refusal removed and with the rename refusal removed (12 passed, 1 failed each); the kept-reason test went red with the first reason overwritten (8 passed, 1 failed); the account pins went red with a per-object account_of read in readable_rows (11 passed, 2 failed), which the old double let pass (13 passed), and with the owner arm reading nothing (11 passed, 2 failed). the workspace suite is green, and the loot-forge suite is green against a throwaway cluster with the CI env block and LOOT_FORGE_TEST_REQUIRE_DATABASE (#2006) f16115c2 · dbf3dbe6…

Renames are not followed. loot's tree maps a path to an address, so a rename is a delete and an add. This list is the history of the name, not of the bytes.
