Review found the mitigation attached to the last landing reading the wrong
code path. EditorSession::open does start with an empty applied log, but that
is the score-only probe constructor. The savable-document path is Ruling B's:
reopen is full replay, stored envelopes load as a committed partition, and
materialization reduces committed plus session operations together. Nothing
resets the depth this bench varies until the checkpoint and pruning machinery
assigned to T4b can write a new canonical_base.
So consequence (e) is withdrawn rather than corrected in place. The ~4,500-edit
wall is a budget on a document's whole accumulated history, and there is no
session reset to lean on -- neither as reassurance about the number nor as
support for the sequencing argument, which rests on paint dominance and does
not need it. T4b's trigger is correspondingly firmer than it read yesterday.
Also: two comments still described the gated core portion as reduce plus
engrave, from before envelope construction was added as a third stage. The
sum they document has included it since the last landing.
Verified in an isolated worktree at HEAD rather than in the working tree,
which still carries the genesis tranche's in-flight work: fmt clean, clippy 0
with and without golden-gate, gate OK with every verdict unchanged (the edits
are documentation only).
