Changes touching this path

• range-diff pairs by the DURABLE CHANGE ID and by nothing else, which resolves a real tension between two of its own acceptance criteria rather than papering over it: AC1 asks for content similarity and AC6 forbids comparing content across a visibility boundary, and a similarity scorer is EXACTLY the construction AC6 rules out. git scores patches because a git commit has no durable identity - loot RECORDS what git infers, and the handle survives re-snapshot, amend and refit, which is precisely what a rework is. so the pairing is exact, O(n+m) instead of O(n times m) content deltas, and STRUCTURALLY INCAPABLE of comparing content: pair takes two slices of identifier pairs, no Workspace, no keyring, no clock, no tree, and its only production builder reads GraphView, which loot-core documents as excluding anything that touches stored bytes. the evidence that the property is held by the TYPES is that the pairing tests need no repo at all. the verb is the FIFTH RENDERING over the delta seam and builds no differ: each pair body is the seam spec, the seam delta and the seam renderer, byte for byte. what the rule cannot pair it SAYS SO ABOUT rather than guessing - no change id from a legacy or git-bridge ingest, copies, which mint a fresh handle by design, and divergent handles, paired in order with the surplus named. the skip count is argued rather than waved past: its three inputs are change ids that are cleartext on every node, recorded addresses the engine already compares without decrypting, and a fact about THIS READER keys, so the most it can say is that two versions differ in paths you cannot open, which any holder computes from the recorded addresses alone. fifteen mutations, all red with counts read, and AC6 positive control pairs an EMBARGOED change and a readable one in the SAME RUN by the SAME RULE, with only the rendering differing. two findings came from looking at real output rather than reasoning: an amend records the superseded version as a PARENT as well as a predecessor, so a different-bases warning fired on every amended pair until same_base learned it, and a superseded version CANNOT BE NAMED BY A SELECTOR at all, so the revset door is the only way to aim at the left-hand side of an amend - a thing this verb can do that diff cannot (#1533) c4b0cd67 · 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.
