The vault held two mirrors of docs/thinking/David/ in two folders, neither
aware of the other. /wrap-up §7 writes 08. Notes/CapableMind/thinking-mirror
at every wrap and is byte-current with upstream. The launchd agent
com.dglidden.thinking-mirror wrote 00. Compass/00b. Constellations/... every
48h, and had been failing since roughly March 2026: last exit 1, ending in
`rsync … > /dev/null 2>&1`, so its own plist StandardOutPath received nothing
and its log has been 0 bytes since 10 Mar. Its tree was 115 files behind.
Nobody noticed the archive job had died because a second, undocumented writer
was quietly doing the same work to a different folder. That is the failure the
duplication caused: not a lost archive, but a lost signal.
The steward asked a previous executor to build that script. Option A chosen:
keep the wrap, retire the agent. Agent unloaded, plist and deployed script
removed. Removing the plist from config/capablemind/ is load-bearing, not
tidiness — setup-capablemind.sh:135 copies every *.plist there into
LaunchAgents, so leaving it would resurrect the retired job on the next setup.
Stale tree deleted from the vault after three independent checks that nothing
was lost: all 151 of its .md files present in the live tree by basename, all
five files that `diff -rq` reported as unique present in both the live tree and
the repo (they only looked unique because the stale tree is flat and upstream
reorganised into l2-constitution/, amendments/, chamber/), and 156 files
tracked in the vault mirror's git HEAD at a58fc00. Siblings daily-log/,
sessions/ and l2-design-narrative.md preserved.
§7 rewritten: it now states it is the only writer, that the destination is a
derived tree no pass may edit, and that the outcome is reported in §8 with the
exit code — never skipped silently. The file already required exactly that of a
failed push in §6.5 and contradicted itself eight lines later.
Frontmatter Specification bumped to v1.0.1 in the vault (steward-authorized,
scoped to this amendment): principle 7 and a new §1a declare mirrored trees out
of scope. Pass 2 brought that subtree to v1.0.0 and reported an end state for
it; the 2026-08-22 wrap rewrote it from source at 23:42 and every edit vanished.
A derived tree cannot hold an edit.
Tracker: the mechanism claim filed earlier today named the launchd agent as the
writer, on nothing stronger than matching upstream content. Wrong agent,
explicitly superseded in place.
