feat(cli): mempalace diary, kg, walk and rate commands (#354, #357, #359, #361) - #404
Merged
Conversation
📝 WalkthroughWalkthroughThe CLI adds diary, knowledge-graph, palace/tunnel traversal, and drawer-rating commands. The changes include daemon/local routing, validation, filtering, output formats, confirmation handling, comprehensive tests, CLI reference documentation, and updated test counts. ChangesCLI command expansion
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to This PR adds several CLI command families, but the current implementation still has concrete correctness issues: tunnel results ignore --limit, server-side failures report the wrong exit status, diary filters can miss older matches, and stdin diary content can be altered. The PR is not merge-ready until these bounded issues are fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

Four MCP tool families had no CLI verb. The daemon exposes all of them
over /mcp; the CLI is the daily surface now that the MCP client surface
is search-only.
mempalace diary write|read mempalace_diary_write / _read
mempalace kg add|invalidate|timeline
mempalace_kg_add / _invalidate / _timeline
mempalace walk mempalace_walk_palace + mempalace_traverse
mempalace rate mempalace_rate_memory
One commit rather than four: the families share the routing scaffolding
(_call_tool_routed, _resolve_tool_format, the _fail_* exits), so splitting
per issue would either duplicate that block or leave three commits that
don't run on their own.
Routing follows cmd_wakeup / cmd_mined — daemon-strict and no --palace
routes to the daemon's /mcp, else the local mempalace.mcp_server tool
function (imported inside the command so --palace can seed
MEMPALACE_PALACE_PATH first). Exit codes match the sibling read commands:
1 for a daemon-side failure, 2 for a client error or an inner-error
envelope. `kg invalidate` is gated behind --confirm and refuses outright
when non-interactive, mirroring _bulk_move_confirm — retracting a fact
rewrites graph history.
Where the issues' proposed flags contradicted the tool schemas, the
schema won and the deviation is documented in the command docstring and
asserted in tests: kg invalidate addresses a fact by subject/predicate/
object (no triple ids, no reason field); kg timeline's --limit and diary
read's --topic/--since filter client-side; walk anchors on
wing/room/entity (no drawer anchor exists in either tool); rate records
a boolean, not a 1-5 score. `kg stats` was verified redundant before
implementing — `mempalace stats --section kg` already renders that block
and `mempalace graph` embeds kg_stats — so it is deliberately absent, and
a test asserts the absence.
Live read-only verification against the production daemon shaped two
details: mempalace_traverse answers with a bare JSON list of hop records
(not a dict envelope), and a JSON-RPC error is no longer reported as
"daemon unreachable" — the daemon answering with a server-side tool
failure is a different problem from the daemon being gone.

Importing mempalace.mcp_server redirects stdout → stderr at module scope (#225) — os.dup2(2, 1) plus sys.stdout = sys.stderr — and only its own main() undoes it, a path no CLI process reaches. Local-path `diary read --json` is exactly what a caller pipes, so the repair now has tests rather than resting on the routing helper being called correctly. Two of them, written against _import_mcp_server by NAME so they hold for the canonical helper (#355) rather than any one implementation: * the local path drops mempalace.mcp_server from sys.modules first, so the import genuinely re-runs the module-scope dup2 — without that, the module is already imported, the hijack never re-fires, and the test passes vacuously * the helper recovers a stdout already aliased to stderr, and is idempotent — a second call must not fault on the closed dup'd fd Both restore sys.modules AND the mempalace.mcp_server package attribute in a finally: leaving only one of them pointing at the freshly-imported copy makes a later patch("mempalace.mcp_server.tool_x") patch a module the CLI never sees, which surfaces as a neighbouring test opening a real palace. Slice of #191 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Live re-verification against the repaired daemon (palace-daemon#238) surfaced a limit the tool schema doesn't mention: the graph backends' timeline() stops at 100 rows and mempalace_kg_timeline doesn't expose the parameter, so `kg timeline JP --limit 200` returns count: 100. The CLI already reported what actually arrived; now --help and the docstring say so instead of implying a wider window was searched. _KG_TIMELINE_TOOL_CAP plus a test lock it. Doc counts derived from this tree rather than carried forward: pytest --collect-only reports 6424 here (main said 6341 before this lane), so README + CLAUDE.md take that number and both generated targets are re-rendered — llms-full.txt embeds those two files, and python-api/cli.md mines cli.py docstrings, so it gains cmd_diary, cmd_kg, cmd_walk and cmd_rate. scripts/check-docs.sh prints docs clean.

Read diary stdin with the byte-exact helper.
Line 6636 uses sys.stdin.read(). The text layer can convert CRLF to LF. The command then permanently stores modified diary content.
Use _read_stdin_exact() and add a CRLF regression test.
Proposed fix
- entry = sys.stdin.read()
+ entry = _read_stdin_exact()As per coding guidelines, “Verbatim always — Never summarize, paraphrase, or lossy-compress user data.”

Make diary filters search beyond the latest 100 entries or clearly report the bounded window.
--topic and --since are applied after fetching only the latest 100 entries, so older matching entries can be omitted while the command implies a complete search. Add backend filtering or pagination, or clearly mark the result as incomplete and document the cap. Add regression coverage for a matching entry outside the fetched window.

Apply --limit to tunnel traversal results.
The tunnel branch does not send or apply limit. Therefore, walk --follow tunnels --limit 1 still emits every returned connection.
Apply client-side truncation to both bare-list and wrapped responses. Add a regression test for table and JSON output.

Register --quiet on every diary and KG leaf parser.
The propagation loop skips nested parent parsers. These leaf parsers register only --json. Commands such as mempalace diary read --quiet and mempalace kg timeline --quiet fail argument parsing.

Dispatch diary and KG after the routing announcement.
These branches return before the routing announcement runs. Interactive diary and KG commands never show whether they use the daemon or local palace.
Move these branches beside the later drawer and duplicate dispatch blocks.

Four MCP tool families get first-class CLI verbs. The daemon exposes all
of them over
/mcp; the CLI is the daily surface now that the MCP clientsurface is search-only.
Architecture
Routing follows the
cmd_wakeup/cmd_minedpattern (#285): daemon-strictand no
--palace→_call_daemon_toolagainst the daemon's/mcp; otherwisethe local
mempalace.mcp_servertool function, imported inside the command so--palacecan seedMEMPALACE_PALACE_PATHbefore mcp_server builds itsmodule config. Exit codes match the sibling read commands: 1 for a
daemon-side failure, 2 for a client error or an inner-error envelope.
--json/--format jsonpasses the tool envelope straight through.The four families share one scaffolding block (
_call_tool_routed,_resolve_tool_format,_fail_daemon/_fail_tool/_fail_client), whichis why this is one commit rather than four — splitting per issue would either
duplicate that block or leave three commits that don't run on their own.
Local-path stdout safety (
8c630699)Importing
mempalace.mcp_serverruns its MCP-stdio protection at modulescope (#225) —
os.dup2(2, 1)plussys.stdout = sys.stderr— undone onlyinside its own
main(). A barefrom . import mcp_serverin a CLI commandtherefore printed the table, or the
--jsondocument, on stderr. Reproducedin a real process:
python -c "from mempalace import mcp_server; print('X')"emits zero bytes on stdout.
diary readandkg timelineare precisely thecommands people pipe, so every local-path import here goes through
_import_mcp_server(), which restores fd 1 viamcp_server._restore_stdout()and then prefers the caller's own stream (
_restore_stdoutputs back thestream the module captured at its import, which in a long-lived process — or
a pytest session that imported it during an earlier test — is no longer
current).
After the third-slot rebase this lane owns no copy of that machinery. The
temporary helper is deleted; the local path now goes through the read family's
_local_mcp_servercontext manager (#356/#362), which composes the drawerfamily's canonical
_import_mcp_server(#355) with a scopedMEMPALACE_PALACE_PATHoverride. That reuse is a net gain over what this lanehad: a
--palaceon one invocation can no longer leak into a later commandthat passed none — verified in a real process (
MEMPALACE_PALACE_PATHisNoneafter the run, and the--jsondocument still lands on fd 1 with stderrdiscarded). The two regression tests were written against the helper name, so
they now guard luna's implementation.
Note on framing: luna established that the stale-snapshot divergence is not
reachable today —
_REAL_STDOUT = sys.stdoutis the first statement inmcp_server's module body, so a first import snapshots exactly the caller's
stream. Her preference-for-the-caller's-stream is robustness against a future
upstream sync moving that statement, not a live bug fix.

Exercised against
http://familiar:8085per the wave brief — reads only; nokg add, nokg invalidate, no diary write against production. Two findingsshaped the code:
mempalace_traverseanswers with a bare JSON list of{room, wings, halls, count, hop, connected_via}records, not a dict envelope. The firstrenderer assumed a dict and crashed with
AttributeErroron real data._traverse_rowsnow normalises both shapes and list-valued fields aresummarised with a count and a preview.
mempalace walk --room decisions --follow tunnels --depth 1returns 10 hops cleanly.DaemonErrorcovers both transport failure and a server-side tool error;printing the second as "unreachable" sends the reader after the network
instead of the query.
walk --wing memorypalace --depth 1anddiary read --agent claude(tableand

traversal on the daemon now fails with
-32000 / OperationalError: the connection is closed—mempalace_kg_timeline(with and without an entity) andmempalace_walk_palaceat every anchor and depth, including the wing/depth-1call that succeeded minutes earlier in the same session.
mempalace_kg_statson the same host still answers (1,328,256 entities / 2,060,900 triples). It
reads like the cached AGE handle going stale with no reconnect — the
#298/#299transient-postgres family, which onlytool_kg_statsguards.Filed for the orchestrator; the CLI surfaces it correctly as exit 1.
Tests
tests/test_cli_diary.py,test_cli_kg.py,test_cli_walk.py,test_cli_rate.py— 83 tests, one file per issue family, patterned ontest_cli_tunnels.py/test_cli_daemon.py. Both routing paths are mocked(daemon via
_call_daemon_tool, local via themempalace.mcp_serverfunction),and they assert exit codes,
--jsonpassthrough, payload mapping, clamping,the client-side filters, the
--confirmgate (flag, interactive yes, interactivedecline, non-interactive refusal, json refusal), and the deliberate absence of
kg stats. Two of them cover the stdout hijack above — one dropsmempalace.mcp_serverfromsys.modulesso the local path's import genuinelyre-runs the module-scope

No

(#402). Note for the cascade: the collected-test count moves with every lane
that lands, so the second and third merges must re-bump those files.
