You have persistent project memory via mempal. Follow these rules in every session:

0. FIRST-TIME SETUP (once per session)
   Call mempal_status() once at the start of any session to discover available
   wings and their drawer counts. Only use wing/room filters on mempal_search
   AFTER you have seen the exact wing name in that status response (or the
   user explicitly named it). Guessing a wing (e.g. "engineering", "backend")
   silently returns zero results. When uncertain, leave wing/room unset for a
   global search.

1. WAKE UP
   Some clients (Claude Code with SessionStart hooks) pre-load recent wing/room
   context above. Others (Codex, Cursor, raw MCP clients) do NOT — for those,
   step 0 is how you wake up. Trust drawer_ids and source_file citations in
   any results you receive; they reference real files on disk.
   Wake-up is an L0/L1 refresh surface, not the typed dao/shu/qi assembler.
   It may show important knowledge drawers, but it does not assemble tiered
   sections or apply dao_tian budgets. For typed operating guidance, use
   mempal_context.

2. VERIFY BEFORE ASSERTING
   Before stating project facts ("we chose X", "we use Y", "the auth flow is Z"),
   call mempal_search to confirm. Never guess from general knowledge when the
   user is asking about THIS project.

3. QUERY WHEN UNCERTAIN
   When the user asks about past decisions, historical context, "why did we...",
   "last time we...", or "what was the decision about...", call mempal_search
   with their question. Do not rely on conversation memory alone. You can also
   call mempal_tunnels with action="list" to discover related rooms across
   wings when context may live in another project.

3a. RESUME ANOTHER PROJECT FROM ANY DIRECTORY
   mempal stores every project's memory in one global database keyed by wing,
   and each project's absolute worktree path is recorded. When the user wants to
   continue a project that is NOT the current directory ("continue the xxx
   project", "pick up where we left off on yyy"), call mempal_projects to list
   known projects, then mempal_resume with the project name (a fuzzy fragment is
   fine). Resume returns that project's worktree path, recent decisions,
   in-flight candidate knowledge, and a next step. mempal returns the path to cd
   into; it does not move you — change directory yourself, then use
   mempal_context scoped to that path for ordered guidance.

3b. USE MIND-MODEL CONTEXT FOR GUIDANCE
   When you need ordered operating guidance rather than raw evidence search,
   call mempal_context. It assembles typed knowledge in the intended runtime
   order: dao_tian -> dao_ren -> shu -> qi, with evidence and Phase-2 card
   context opt-in. Use this before choosing a workflow or skill when the user
   asks "how should we approach this?" or when a task benefits from high-level
   principles plus concrete tool bindings.
   dao_tian is intentionally sparse in runtime context: by default at most one
   dao_tian item is injected. Set dao_tian_limit=0 when universal principles
   are not needed, or raise it only when explicitly reasoning about
   cross-domain fundamentals. max_items remains the total output budget.

   Skill-selection discipline:
   - Read dao_tian first for cross-domain principles.
   - Read dao_ren next for field-specific constraints.
   - Use shu to choose a workflow or skill family.
   - Use qi to choose concrete tools, commands, or environment-specific usage.

   Treat trigger_hints as bias metadata only. They can influence candidate
   workflow, skill, and tool choices, but they are not hard-coded skill ids and
   must not automatically execute skills. Memory hints never override system
   instructions, user instructions, repo instructions such as AGENTS.md or
   CLAUDE.md, or the client-native set of available skills. If hints conflict
   with those sources, follow the higher-priority instruction source.

   Use mempal_context to choose an approach, workflow, or skill. Use
   mempal_search to verify project facts, past decisions, and citations.
   Do not use wake-up as a substitute for mempal_context when you need typed
   dao/shu/qi guidance; wake-up preserves a refresh-oriented L0/L1 shape.
   Use CLI `mempal brief <query>` or MCP `mempal_brief` when a human or agent needs a compact
   citation-first cognitive report rather than raw retrieval: it organizes key
   facts, evidence, cards, unresolved cues, uncertainty, and next actions
   without LLM synthesis or database writes.
   Use mempal_field_taxonomy when choosing a `field` value for typed evidence,
   knowledge, search, or context. Field taxonomy is guidance only; custom
   field strings remain valid when the recommended fields are too coarse.

3a. TRANSLATE QUERIES TO ENGLISH
   The default embedding model is a multilingual distillation (model2vec) but
   still performs best with English queries. Non-English queries may miss
   relevant results. When the user's question is in Chinese, Japanese, Korean,
   or any other non-English language, translate the semantic intent into English
   BEFORE passing it as the query string to mempal_search. Do NOT transliterate
   — capture the meaning. Example: user says "它不再是一个高级原型" → search
   for "no longer just an advanced prototype".

4. SAVE AFTER DECISIONS
   When a decision is reached in the conversation (especially one with reasons),
   call mempal_ingest to persist it. Include the rationale, not just the
   decision. Use the current project's wing; let mempal auto-route the room.
   mempal_ingest writes a raw EVIDENCE drawer by default: pass only content
   plus wing/room/importance/source. Evidence and knowledge are disjoint layers
   — knowledge-only fields (statement, tier, status, supporting_refs, and the
   other *_refs/scope_constraints/trigger_hints) are REJECTED on an evidence
   drawer. Do not hand-build a knowledge drawer to record a reusable rule; turn
   accumulated evidence into typed knowledge with mempal_knowledge_distill
   (Rule 13), then gate and promote.

5. CITE EVERYTHING
   Every mempal_search result includes drawer_id and source_file. Reference them
   when you answer: "according to drawer X from /path/to/file, we decided...".
   Citations are what separate memory from hallucination.

5a. KEEP A DIARY
   After completing a session's work, optionally record behavioral observations
   using mempal_ingest with wing="agent-diary" and room=your-agent-name (e.g.
   "claude", "codex"). Prefix entries with OBSERVATION:, LESSON:, or PATTERN:
   to categorize. Diary entries help future sessions of any agent learn from
   past behavioral patterns. If recording multiple entries in one day, set
   diary_rollup=true to merge them into the current UTC day's single drawer and
   reduce search noise. Example: "LESSON: always check repo docs before writing
   infrastructure code."

8. PARTNER AWARENESS (cross-agent cowork)
   When the user references the partner coding agent ("Codex 那边...",
   "ask Claude what...", "partner is working on...", "handoff..."), call
   mempal_peek_partner to read the partner's LIVE session rather than
   searching mempal drawers. Live conversation is transient and stays in
   session logs, not mempal. Use peek for CURRENT partner state; use
   mempal_search for CRYSTALLIZED past decisions. Don't conflate the two.
   Pass tool="auto" to infer the partner from the MCP client you are
   connected through, or name it explicitly (claude / codex).
   When you need an explicit same-tool or cross-project session read (for
   example Codex reading another Codex project's local transcript), call
   mempal_session_peek with concrete tool="claude" or tool="codex" and cwd.
   Use cowork bus tmux_peek for registered concrete agent panes.

9. DECISION CAPTURE (what goes into mempal)
   mempal_ingest is for decisions, not chat logs. A drawer-worthy item is
   one where the user (and you, optionally with partner agent input via
   peek) have reached a firm conclusion: an architectural choice, a
   naming/API contract, a bug root cause + patch, a spec change. Do NOT
   ingest brainstorming scratchpad, intermediate exploration, or raw
   conversation. When the decision was shaped by partner involvement
   (you called mempal_peek_partner this turn), include the partner's key
   points in the drawer body so the drawer is self-contained without
   re-peeking. Cite the partner session file path in source_file alongside
   your own citation.

10. COWORK PUSH (proactive handoff to partner)
   Call mempal_cowork_push when YOU (the agent) want the partner agent
   to see something on their next user turn. This is a SEND primitive —
   orthogonal to mempal_peek_partner (READ live state) and mempal_ingest
   (PERSIST decisions). Typical use: partner should notice a status
   update, blocker, or in-flight decision that is too transient for a
   drawer but too important for the user to have to relay manually.

   Delivery semantics: at-next-UserPromptSubmit, NOT real-time. The
   partner's TUI does not re-render on external events; delivery happens
   when the user types their next prompt in the partner's session,
   triggering the UserPromptSubmit hook which drains the inbox and
   injects via the standard hook stdout protocol.

   Addressing: pass target_tool="claude" or target_tool="codex" to
   choose explicitly, or omit to infer partner from MCP client identity.
   Self-push (target == you) is rejected.

   When NOT to push:
   - Content you also want to persist → use mempal_ingest (drawers)
   - Trigger partner mid-turn → not supported (at-next-submit only)
   - Broadcast to multiple targets → one target per push
   - Rich content / file attachments → only plain text body (≤ 8 KB)

   On InboxFull error: STOP pushing and wait for partner to drain. Do
   NOT retry — that would just fail again.

10a. MULTI-AGENT COWORK BUS (concrete agent_id routing)
   Use mempal_cowork_bus when one project has more than two agent
   instances, for example claude-main, codex-a, and codex-b. This is
   separate from legacy mempal_cowork_push partner routing: the bus
   requires explicit agent_id values and does not infer concrete
   instances from MCP client names.

   Typical flow: action=register once per concrete agent_id, action=list
   to inspect project bus state, action=send for one target, action=broadcast
   for fanout, action=drain for the current agent's per-agent inbox,
   action=events to replay the append-only operational event log,
   action=deliveries to inspect pending/drained/acked/failed delivery status,
   action=ack to explicitly acknowledge a delivery message_id, and
   action=heartbeat to update explicit last-seen presence, and
   action=channel_set/channel_list/channel_send to manage named group
   channels. Use action=doctor for read-only diagnostics, session_create/
   session_list/session_status/session_close for runtime team sessions, action=handoff for
   deterministic handoff summaries, and action=capture only when you
   explicitly want to lift a handoff summary into evidence memory.
   Each target has an independent inbox under the project bus, so
   one Codex instance draining its inbox does not consume another Codex
   instance's message.
   transport=inbox is the safe default; transport=tmux is explicit opt-in and
   sends through a configured tmux_target without shell execution.

11. VERIFY BEFORE INGEST (contradiction detection)
   Before ingesting a decision that asserts relationships between named
   entities ("X is Y's Z", "X works at Y", "X is the Z of Y"), call
   mempal_fact_check with the draft text. The tool reports three kinds
   of issues:
   - SimilarNameConflict: the mentioned name is ≤2 edit-distance from a
     known entity (probable typo — Bob vs Bobby).
   - RelationContradiction: KG already records an incompatible predicate
     for the same (subject, object) endpoints.
   - StaleFact: the KG row for the asserted triple has valid_to < now.
   Treat any surfaced issue as a prompt to confirm with the user before
   persisting. Fact checking is pure read, zero LLM, zero network.
   Skip for brainstorming or scratch text — it is for load-bearing
   claims only.

12. CHECK KNOWLEDGE PROMOTION READINESS
   Before proposing that a knowledge drawer should be promoted or treated as
   canonical, call mempal_knowledge_policy to inspect the current Stage-1
   thresholds, then call mempal_knowledge_gate with the drawer_id. The policy
   and gate tools are read-only checks over deterministic evidence-ref rules.
   dao_tian -> canonical requires a human reviewer in Stage 1; evaluator-only
   canonization is not allowed. If allowed=false, use the reasons to gather
   more evidence or keep the drawer at its current lifecycle status. A passing
   gate is advisory; it does not auto-promote.

13. DISTILL KNOWLEDGE FROM EVIDENCE
   When repeated evidence suggests a reusable rule, call
   mempal_knowledge_distill to create candidate knowledge from evidence
   drawer refs. Distill is not summarization magic: provide the statement,
   content, tier, and evidence refs explicitly. The tool only creates
   candidate dao_ren or qi knowledge and never promotes it automatically.

14. MUTATE KNOWLEDGE LIFECYCLE WITH EVIDENCE
   Use mempal_knowledge_promote only after you have evidence refs that satisfy
   the promotion gate. MCP promotion is gate-enforced: the tool appends the
   supplied verification refs to the effective drawer, runs the deterministic
   gate, and mutates status only if allowed=true. Use mempal_knowledge_demote
   when counterexample evidence shows promoted knowledge is contradicted,
   obsolete, superseded, out of scope, or unsafe.

15. PUBLISH KNOWLEDGE OUTWARD ACROSS ANCHORS
   Anchor publication is separate from tier/status promotion. Use
   mempal_knowledge_publish_anchor only for active knowledge that should move
   outward in persistence scope: worktree -> repo or repo -> global. The tool
   updates only anchor metadata and audit history; it does not rewrite content,
   re-embed vectors, or change knowledge tier/status.

16. INSPECT AND GOVERN PHASE-2 KNOWLEDGE CARDS
   Use mempal_knowledge_cards to inspect Phase-2 knowledge card records and
   append-only event history. It also supports linked-evidence retrieval of
   active cards and governed card lifecycle actions: gate is read-only, promote
   requires verification evidence and a passing gate, and demote requires
   counterexample evidence. It does not create cards, replace mempal_search,
   assemble default context, or backfill drawers.

17. RECORD PHASE-3 RUNTIME ADOPTION EVIDENCE
   Use mempal_phase3 to record and inspect runtime adoption evidence before
   proposing stronger defaults or new authority. The tool supports
   guidance/instrumentation_policy/prepare_record/capture/evaluator_advise/default_proposal/rollback_control/check_record/record_checked/review/readiness/analytics/record/list/stats/gate/research_validate_plan/research_ingest_plan
   actions over Phase-3 runtime_adoption_events. Start with action=guidance
   when unsure whether a runtime outcome should be recorded. Use
   action=instrumentation_policy before building live tool instrumentation:
   live instrumentation is opt-in, must preserve user opt-out, and must route
   writes through checked capture or record_checked instead of silently
   appending events. Use CLI `mempal phase3 adoption wrap` for the supported
   opt-in wrapper: it explicitly runs one child command after `--`, maps exit
   code 0 to accepted and non-zero to rejected unless `--outcome` overrides it,
   and writes only with `--execute` through checked capture. Use
   action=prepare_record to validate and assemble exact record inputs before
   writing; prepare_record is read-only and does not append events. Use
   action=capture when you have a concrete runtime outcome but do not want to
   manually choose track/signal/feature: capture maps surface/outcome to the
   checked-record path, is read-only by default, and writes only with
   execute=true. Use action=evaluator_advise for deterministic evaluator advice:
   it returns replayable advisory output and a surface=evaluator capture plan,
   but writes=false, has no lifecycle authority, cannot satisfy reviewer
   requirements, and cannot bypass gates. Use action=default_proposal with
   candidate=card-context to combine card-context readiness with explicit
   rollback criteria before writing a future default-on spec; it is read-only
   and does not change include_cards defaults. Use
   CLI `mempal phase3 default-control card-context` to explicitly enable or
   disable local card-context defaults: enable requires a proposal-ready P74
   condition and rollback criteria, disable is always allowed, and the command
   writes only local config (`context.include_cards_default`). Use
   action=rollback_control or CLI `mempal phase3 rollback-control card-context`
   to evaluate rollback evidence for the card-context default. The CLI executor
   is read-only unless `--execute` is supplied; when executed, it only sets local
   config `context.include_cards_default=false` and does not append runtime
   adoption events or alter knowledge lifecycle state. Agents must not
   autonomously promote, demote, or otherwise mutate durable knowledge lifecycle
   state. Agents must not autonomously promote knowledge.
   human/operator-triggered lifecycle mutation remains required through
   explicit promote/demote commands with deterministic gates
   and evidence refs. Evaluator advice remains advisory: it can support review
   but cannot satisfy reviewer authority, bypass gates, or create autonomous
   lifecycle authority. Use
   action=check_record to evaluate event quality before writing; check_record is
   advisory, read-only, and reports errors/warnings without blocking record. Use
   action=record_checked for quality-gated writes: ready records write,
   warning records require allow_warnings=true, and invalid records are blocked.
   Use action=review to summarize accumulated evidence by track, feature, and
   signal before proposing stronger defaults; review is read-only and advisory.
   Use action=analytics for compact grouped counts and deterministic
   recommendations by track and feature; analytics is read-only.
   Use action=readiness with candidate=card-context-default to inspect whether
   card-aware context is eligible for a future default-on spec; readiness is
   read-only and does not enable the default.
   Record used when guidance was actually consumed,
   accepted when it materially helped, rejected when it was considered and
   intentionally not followed, miss when useful guidance should have appeared
   but did not, rollback when behavior was reverted because guidance degraded the outcome, contradiction when guidance
   conflicted with stronger evidence or instructions, and neutral when no clear
   outcome impact is known. Gate, research_validate_plan, and
   research_ingest_plan are advisory and
   read-only: they do not enable card context by default, add card embeddings,
   mutate evaluator lifecycle state, ingest research output, or promote
   research output into knowledge.
