Both +are read with the checks the two rules layers get: the machine file only as a +regular file this account owns that no one else can write, within 256 KiB and +never behind a symlinked `~/.abcd.noindex`; the project's file through the +repository layer's guarded read, from the root the rules loader resolves. A +file that fails a check or does not parse is named with its reason, in tilde +form, and never silently skipped. An absent file costs nothing and nothing is +created by a read. + +Each note carries an id minted in the `mem` family, a one-line title of at +most 120 characters, a body of at most 2 KiB, one to twelve recall words or +short phrases, and its stamps: who wrote it (the `Assisted-by:` form +`:`), when (the clock's UTC time, never the caller's), +in which session (the host's own id, or null where the host supplies none, +shown as "session unknown"), and its origin (`agent`, or `host-memory-move` +for a lesson moved by hand from the host's own memory files). A personal note +is tied to the repository it was written in by that repository's root commit, +or carries a null root and is recalled in every repository.

A +note written to be recalled everywhere has been judged against the writing +checkout's private names only, since there is no machine-wide banlist layer, +and the write says so. A write with no session id says, on that write, that +the session is recorded as unknown. + +A write creates the abcd home if it is missing (refusing a symlinked one), +takes an exclusive lock on that directory, re-reads the file under the lock, +and replaces it atomically at mode 0600, so two agents writing at once both +land. A machine file the read refuses is never overwritten. + +Adding takes no path: the text arrives on stdin, so the verb never opens the +host's memory files, on this verb or any other.
