Changes touching this path

• bisect grows log, replay and terms, and the replay refuses WHOLE at a gap rather than replaying up to it, because a partial session is INDISTINGUISHABLE FROM A WHOLE ONE IN THE ARTIFACT: status renders both identically, the search then runs from a range missing a bound it was TOLD about, and the only evidence is a warning that has scrolled away. all-or-nothing has no partial result to mistake. the pre-flight resolves every id against the graph before writing anything and names EVERY missing change with the line that asked for it, and on a shallow position it says so and names --deepen rather than pull. SESSION_VERSION stays 1 and that is the shape of the preservation criterion rather than a promise about it: the terms pair is a TRAILING codec section written only when non-default, so a default session is byte identical to what the previous release wrote and a pre-1532 session still decodes. the transcript is an INPUT and what is frozen is its GRAMMAR rather than its emitted text - what the parser accepts today it accepts forever with the same meaning, and later work may add directives rather than re-read existing lines. an unparseable line refuses the whole file and points at the line, which is the rule 1516 set for an unreadable ignore file, and EMPTY or all-comment is refused TOO, because zero directives and a session with no marks are DIFFERENT FACTS and a truncated download is exactly how the first arrives looking like the second. ids are full 64 hex only, no prefixes and no HEAD, because a transcript is read on a machine where neither means what it meant there. the vocabulary TRAVELS with the transcript: a terms line rides ahead of the marks and replay resolves mark words against a RUNNING table, so it round trips, and a transcript written under old and new whose terms line is missing is REFUSED rather than re-read as good and bad - the one reading that would silently FLIP A VERDICT. the rename ADDS a spelling rather than retiring one, so bisect good keeps working afterwards, and that is safe ONLY because a term may not shadow a subcommand name, which is what makes the inversion terms bad good unspellable. two of its own assertions were not AIMED until they were fixed: the start assertion was vacuous because the fixture made start and the transcript bad the same id, repaired by finalizing a sixth change between the log and the replay, and a doc claimed its consequence one assertion earlier than the one that fires. and the tests produced a finding worth keeping: writing the transcript INSIDE the repo makes it an uncaptured edit, so replay refuses over work the operator did not knowingly make - the guard was deliberately NOT widened, since a replay checks a midpoint out and must refuse over the same work bisect start does, so instead the refusal names the likely culprit and the smoke test ASSERTS that refusal rather than arranging to avoid it (#1532) 05f9263e · 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.
