Catchup throttle: when the agent is >50% behind the conversation
window (>25KB of transcript growth since last spawn), block and
wait up to 30s for the current agent to finish. Prevents the agent
from falling behind during heavy reading/studying.
Reflection agent: runs every 100KB of transcript growth. Reads
walked nodes from surface-observe, follows links in unexpected
directions, outputs a short dreamy insight. Previous reflections
are injected into the conversation context.
Updated reflect.agent prompt to use {{input:walked}} from
surface-observe state dir and {{conversation:20000}} for lighter
context.

Links to nodes created after the conversation window start are
tagged with (new) in memory_render output. The surface prompt
tells the agent not to surface these — they're its own recent
output, not prior memories. Observe can still see and update them.
POC_MEMORIES_OLDER_THAN env var set from the oldest message
timestamp in the conversation window.

- journal_new(name, title, body): name becomes the node key,
title goes in the ## heading. Agent picks short searchable names.
- Auto-dedup: if the key exists, append -2, -3, etc.
- CLI journal write also requires a name argument now.

Episodic entries should be grouped by creation date, not last
update date. Fixes digest generation potentially assigning
updated entries to the wrong day.

- journal_new: key is slugified title (agent names things properly)
- journal_tail: sort by created_at (immutable), not timestamp (mutable)
- journal_update: find latest by created_at
- {{latest_journal}}: query by NodeType::EpisodicSession, not "journal" key
- poc-memory journal write: requires a name argument
- Removed all journal#j-{timestamp}-{slug} patterns from:
- prompts.rs (rename candidates)
- graph.rs (date extraction, organize skip list)
- cursor.rs (date extraction)
- store/mod.rs (doc comment)
- graph.rs organize: filter by NodeType::Semantic instead of key prefix
- cursor.rs: use created_at for date extraction instead of key parsing

- journal_new: create EpisodicSession node with auto-generated key
- journal_tail: query by node_type, not by parsing a monolithic node
- journal_update: find latest EpisodicSession by timestamp
- No string key matching anywhere — all typed
- Fixes journal entries not appearing in 'poc-memory journal tail'
- Also: added --provenance/-p filter to 'poc-memory tail'
- Also: fix early return in surface_observe_cycle store load failure
- Also: scale max_turns by number of steps (50 per step)

- Remove unused now_secs(), parse_json_response, any_alive, Regex import
- Signal handler: replace Mutex with AtomicPtr<c_char> for signal safety
(Mutex::lock in a signal handler can deadlock if main thread holds it)
- PidGuard Drop reclaims the leaked CString; signal handler just unlinks
- scan_pid_files moved to knowledge.rs as pub helper
- setup_agent_state calls scan_pid_files to clean stale pids on startup

- Bail command moved from hardcoded closure to external script
specified in agent JSON header ("bail": "bail-no-competing.sh")
- Runner executes script between steps with pid file path as $1,
cwd = state dir. Non-zero exit stops the pipeline.
- PID files simplified to just the phase name (no JSON) for easy
bash inspection (cat pid-*)
- scan_pid_files helper deduplicates pid scanning logic
- Timeout check uses file mtime instead of embedded timestamp
- PID file cleaned up on bail/error (not just success)
- output() tool validates key names (rejects pid-*, /, ..)
- Agent log files append instead of truncate
- Fixed orphaned derive and doc comment on AgentStep/AgentDef
- Phase written after bail check passes, not before

- AgentStep with phase labels (=== PROMPT phase:name ===)
- PID files in state dir (pid-{PID} with JSON phase/timestamp)
- Built-in bail check: between steps, bail if other pid files exist
- surface_observe_cycle replaces surface_agent_cycle + journal_agent_cycle
- Reads surface output from state dir instead of parsing stdout
- Pipelining: starts new agent if running one is past surface phase
- link_set upserts (creates link if missing)
- Better error message for context window overflow

Split agent prompts on === PROMPT === delimiter. Each step runs as
a new user message in the same LLM conversation, so context carries
forward naturally between steps. Single-step agents are unchanged.
- AgentDef.prompt -> AgentDef.prompts: Vec<String>
- AgentBatch.prompt -> AgentBatch.prompts: Vec<String>
- API layer injects next prompt after each text response
- {{conversation:N}} parameterized byte budget for conversation context
