- 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

Links now display as \`key\` instead of bare text, and overflow
shows memory_links() tool call format instead of CLI command.

Creates the link if it doesn't exist, avoiding wasted agent turns

Override the agent output/input directory for manual testing.
Sets POC_AGENT_OUTPUT_DIR so output() writes there and

- output(key, value): write named results to agent state dir,

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

Replaced debug_visible bool with an Overlay enum. F1 shows the
context/debug screen (Ctrl+D still works as alias), F2 shows the
agents screen (placeholder for now — will show surface, observe,
reflect, journal status). Esc closes any overlay.

Personality is identity, not memory. Memory is nodes loaded during

mem% was always 0 because memory_tokens was hardcoded to 0. Now
counts personality context + loaded nodes from memory tool calls.
Also calls measure_budget + publish_context_state after memory tool
dispatch so the debug screen updates immediately.

Exposes the full query language as a tool: filtering, sorting, field
selection, neighbor walks. Examples:
degree > 10 | sort weight | limit 5
neighbors('identity') | select strength
key ~ 'journal.*' | count
Also added query_to_string() in the parser so queries return strings
instead of printing to stdout. Updated memory-instructions-core to
list all current tools (added memory_query and journal, removed
CLI commands section and nonexistent memory_search_content).

ContextSource::Store was handled identically to File — reading .md
files from disk. Now uses MemoryNode::load() to read from the capnp
store. This is why personality wasn't showing correctly in poc-agent:
store-sourced context groups (cognitive-modes, stuck-toolkit,
instructions, memory-instructions-core) were being looked up as
flat files and silently missing.

- Removed write/search/mark_used static methods from MemoryNode —
those are store ops, not MemoryNode concerns
- Removed SearchResult duplicate — use query::engine::SearchResult
- Simplified Link to (String, f32) tuple — inline detection moved
to render()
- Collapsed tool definitions to one-liners
- Consolidated store-mutation tools into with_store() helper
- Supersede uses store directly instead of MemoryNode round-trip

MemoryNode moved from agent/memory.rs to hippocampus/memory.rs — it's
a view over hippocampus data, not agent-specific.
Store operations (set_weight, set_link_strength, add_link) moved into
store/ops.rs. CLI code (cli/graph.rs, cli/node.rs) and agent tools
both call the same store methods now. render_node() delegates to
MemoryNode::from_store().render() — 3 lines instead of 40.

Memory tools now dispatch through a special path in the runner (like
working_stack) instead of the generic tools::dispatch. This gives them
&mut self access to track loaded nodes:
- memory_render/memory_links: loads MemoryNode, registers in
context.loaded_nodes (replace if already tracked)
- memory_write: refreshes existing tracked node if present
- All other memory tools: dispatch directly, no tracking needed
The debug screen (context_state_summary) now shows a "Memory nodes"
section listing all loaded nodes with version, weight, and link count.
This is the agent knowing what it's holding — the foundation for
intelligent refresh and eviction.

Every memory tool call was spawning a poc-memory subprocess. Now uses
MemoryNode and direct Store API calls:
- memory_render: MemoryNode::load() + render()
- memory_write: MemoryNode::write() via store.upsert_provenance()
- memory_search: MemoryNode::search() via search engine
- memory_links: MemoryNode::load() + iterate links
- memory_link_add: store.add_relation() with Jaccard strength
- memory_link_set: direct relation mutation
- memory_used: store.mark_used()
- memory_weight_set: direct node.weight mutation
- memory_supersede: MemoryNode::load() + write() + weight_set()
No more Command::new("poc-memory") in this module.

MemoryNode is the agent's live view of a loaded memory node — key,
content, links, version, weight. Operations (load, write, search,
mark_used) go directly through the store API instead of spawning
poc-memory subprocesses.
This is the foundation for context-aware memory: the agent can track
which nodes are loaded in its context window, detect changes, and
refresh regions when nodes are updated.

Both hippocampus/config.rs and agent/config.rs read from the same
config file (~/.config/poc-agent/config.json5). Having two separate
implementations was a footgun — load_context_groups() was duplicated
three times across the codebase.
Merged into src/config.rs:
- Config (memory settings, global get()/reload())
- AppConfig (agent backend/model settings, figment-based loading)
- SessionConfig (resolved agent session, renamed from agent's Config)
- Single ContextGroup/ContextSource definition used everywhere
Eliminated: duplicate load_context_groups(), duplicate ContextGroup
definition in identity.rs, duplicate config file path constants.

Eliminates the circular dependency between poc-agent and poc-memory by
moving all poc-agent source into poc-memory/src/agent/. The poc-agent
binary now builds from poc-memory/src/bin/poc-agent.rs using library
imports. All poc_agent:: references updated to crate::agent::.

Make Session::from_env() and Session::seen() the public API for
accessing session state. Internal callers converted to use session
methods. Search automatically filters already-surfaced nodes when
POC_SESSION_ID is set.
Extract response after '=== RESPONSE ===' marker before parsing
for REFLECTION/NEW RELEVANT MEMORIES. The agent runner dumps the
full log (turns, think blocks) to stdout.
`memory-search surface` and `memory-search reflect` run the agent
directly, parse the output, and dump rendered results to stdout.
Useful for testing with `watch memory-search reflect`.
Thread temperature parameter from agent def header through the API
call chain. Agents can now specify {"temperature": 1.2} in their
JSON header to override the default 0.6.
Also includes Kent's reflect agent prompt iterations.
Add reflect.agent — a lateral-thinking subconscious agent that
observes the conversation and offers occasional reflections when the
conscious mind seems to be missing something.
Refactor memory_search.rs: extract generic agent_cycle_raw() from
the surface-specific code. PID tracking, timeout, spawn/reap logic
is now shared. Surface and reflect agents each have their own result
handler (handle_surface_result, handle_reflect_result) wired through
the common lifecycle.
Add `agent: bool` field to ContextGroup (default true) so agents get
personality/identity context without session-specific groups (journal,
where-am-i). Agents now get the full identity.md, reflections.md,
toolkit, etc. instead of the compact core-personality loader.
New {{agent-context}} placeholder resolves all agent-tagged groups
using the same get_group_content() as load-context.
The CLI render command was marking keys as seen in the user's session
whenever POC_SESSION_ID was set. Agent processes inherit POC_SESSION_ID
(they need to read the conversation and seen set), so their tool calls
to poc-memory render were writing to the seen file as a side effect —
bypassing the dedup logic in surface_agent_cycle.
Fix: set POC_AGENT=1 at the start of cmd_run_agent (covers all agents,
not just surface), and guard the CLI render seen-marking on POC_AGENT
being absent. Agents can read the seen set but only surface_agent_cycle
should write to it.

Move the hook logic from the memory-search binary into a library module
(poc_memory::memory_search) so poc-hook can call it as a direct function
instead of spawning a subprocess with piped stdin.
Also convert the node render call in surface_agent_cycle from
Command::new("poc-memory render") to a direct crate::cli::node::render_node()
call, eliminating another subprocess.
The memory-search binary remains as a thin CLI wrapper for debugging
(--hook reads from stdin) and inspection (show_seen).

Add surface_hooks config field — list of hook event names that trigger
the surface agent (e.g. ["UserPromptSubmit"]). Empty list disables it.
Reduce surface agent search from 3-5 hops to 2-3 to keep prompt size

The placeholder resolver re-scanned from the beginning of the string
after each expansion. If expanded node content contained {{...}}
patterns (which core-personality does), those got expanded recursively.
Cyclic node references caused infinite string growth.
Fix: track a position offset that advances past each substitution,
so expanded content is never re-scanned for placeholders.

The backward JSON scanner (JsonlBackwardIter and TailMessages) was
matching } characters inside JSON strings — code blocks full of Rust
braces being the primary offender. This caused:
- Quadratic retry behavior on code-heavy transcripts (wrong object
boundaries → serde parse failure → retry from different position)
- Inconsistent find_last_compaction_in_file offsets across calls,
making detect_new_compaction fire repeatedly → context reload on
every hook call → seen set growing without bound
Fix: add string-boundary tracking with escaped-quote handling to
the close-brace finder loop, matching the existing logic in the
depth-tracking loop.

- Remove MEMORY_FILES constant from identity.rs
- Add ContextGroup struct for deserializing from config
- Load context_groups from ~/.config/poc-agent/config.json5
- Check ~/.config/poc-agent/ first for identity files, then project/global
- Debug screen now shows what's actually configured
This eliminates the hardcoded duplication and makes the debug output
match what's in the config file.
The surface agent result consumer in poc-hook was writing to the seen
file but not the returned file, so surfaced keys showed up as
