Staging default moves out of ~/.cache to <palace-root>/pi-stage (pi) and
<palace-root>/opencode-stage (opencode), resolved with mempalace's own
palace-path precedence ($MEMPALACE_PALACE_PATH -> $MEMPAL_PALACE_PATH ->
~/.mempalace/config.json -> ~/.mempalace/palace), then dirname.
Why: the convos miner keys dedup on the *staged* path, so a wiped stage plus a
sync scoped to include it prunes the drawers mined from those sources --
deleting memories, not a cache. Under ~/.cache that state was reachable by
anything treating a cache as disposable. Staging inside the palace makes the
coupling structural: the stage cannot be wiped without touching the palace
itself. Overrides ($MEMPALACE_PI_STAGE / $MEMPALACE_SESSION_STAGE, --stage) are
unchanged. Note the old default had never been created on any host, so this
closed a latent hazard, not a live one.
Measured, and the docs now claim only this much: sync prunes only within the
scope it is given -- wing-only, 1299 scanned / 1299 out of scope / 0 removed;
scoped at the palace root, 651 kept / 648 out of scope. The previous blanket
"sync prunes every drawer" wording overstated it, which is a liability: the next
reader disproves the overstatement and discards the real constraint with it.
Also in this change:
- cron log dir ~/.cache/mempalace-session -> ~/.cache/mempalace-logs. The stage
left that namespace, so the old name now read as "the stage".
- AGENTS.md: the convos miner *does* check mtime (verified against upstream
convo_miner.py); the previous "no mtime check" claim was wrong.
- smoke-test assertions use `mktemp -d` for --sessions-dir. One pointed at /tmp,
which still held earlier synthetic transcripts, so a --dry-run exported a fake
session into the real stage: --dry-run skips the mine, not the export.
docs/phase-1-exposure-runbook.md -- the newt/DNS/auth step that RFC 001 and the
synlig runbook leave open (runbook section 4, items 2 and 5). Port 8765 at /mcp,
newt targets 172.17.0.1, and the authentication is the single shared bearer
token (RFC 6.2, decided 2026-08-09) rather than per-device proxy users. The
latter cannot work today: mempalace validates exactly one token, and Pangolin's
SSO/PIN/password are browser-shaped while every client here is a headless
JSON-RPC POST -- enabling that protection breaks the clients it protects. The
per-device axis that *does* exist is the feeder's SSH key + per-device inbox.
New finding recorded there: a loopback bind does not merely 403 behind a tunnel
(already known, runbook 2.4) -- it also silently starts the server with no token
at all, because auto-minting is gated on the bind being non-loopback.
extensions/pi/README.md: the HTTP transport IS authenticated as of mempalace
3.6.0; the "sessionless and unauthenticated" note dated from the v1.3.0 era.
Closes the RFC section 8 Phase-0 hygiene item.
Until opencode session-stopping hooks land upstream, mempalace-session
is the entire mechanism that gets opencode conversations into the
palace — skip it and session history stays trapped in a local SQLite
DB, invisible to semantic search. Previous docs covered setup well
but were thin on when and how often to run it.
- ARCHITECTURE.md §5: replace the one-line 'When to re-mine' note with
a full Operational Routine section — triggers, cadence, relationship
to the session lifecycle, automation pointers, verification.
- SKILL.md: add an Operational Routine section aimed at agents —
when to suggest invoking the tool, cadence guidance, how to
distinguish this producer-side tool from the consumer-side
mempalace skill's in-session habits.
- README.md: add 'Keeping it fresh' subsection pointing at contrib/
and the full docs.
contrib/ ships three ready-to-use templates:
- systemd/mempalace-session.{service,timer} — user units with weekly
Mon 03:00 schedule, Persistent=true catch-up, RandomizedDelaySec for
fleet-wide jitter, ConditionPathExists guard for opencode-less boxes,
Nice+IOSchedulingClass=idle so it never fights interactive work.
- cron/mempalace-session.cron — sample crontab entry with log
redirection and clear USER-substitution instructions.
- README.md with install/verify/uninstall recipes for both, a chooser
table (systemd vs cron), container/devbox caveats, and tuning notes
(daily vs weekly vs monthly trade-offs).
The user's LATER-list item 'wrap mempalace-session in cron/systemd
timer for true auto-save coverage' is now actionable: a single
systemctl --user enable --now command stands it up.
