The code never reads a file it is about to replace just to count its lines: stat
gives the size and the age, and the new content's line count is known without
reading anything. The spec overpromised the old count.
Ten tasks: the path policy and its operations, the approval dialog and its ledger,
seven tools, three preferences, what the model is told, the hook and setup screen
wiring, the README, and a verification task that mutation checks the policy rather
than trusting the suite.
Seven file tools behind a path policy and an approval step, with the platform
findings that shaped it: extensions are unsandboxed Node, confirmAlert exists,
rememberUserChoice does not, and environment.supportPath is the one directory an
extension is invited to write to.
Records the decisions taken with the user (read, write, edit and destructive
tools; one approval per path per answer; home minus a credential denylist; extra
roots in preferences) and the assumptions that follow from them, including the
two that go beyond the questions asked: delete and move asking every time, and
file access being off until switched on.
