feat(agentic): scope file/command tools to an agent workspace root

Confine the agentic file tools (read_file, write_file, list_files, grep)
to a configured workspace subtree via a lexical path check, and run
run_command with its cwd set to that root. Root comes from state key
"agent_workspace_root" or env NEURON_AGENT_ROOT. When no root is set,
behavior is unchanged (unscoped) for backward compatibility.

Defense-in-depth, NOT a hard boundary: the lexical guard does not resolve
symlinks and cannot stop an arbitrary shell command from cd-ing out of the
root. Real confinement needs runtime support (cwd-locked exec / sandbox-exec
/ chroot) in el_runtime.c.

Compile-checked with elc (darwin arm64); not link/run-gated locally
(darwin elb unavailable). Needs a soul build + smoke test before merge.

+# Memory Recall Bug — Handoff for Will
+
+**Reported by:** Tim (via the Neuron UI chat)
+**Diagnosed by:** Claude (Claude Code session), 2026-06-05
+**Symptom:** The soul can't recall anything specific — e.g. "do you remember the jokes
+from that night with Will, Tim, and April?" → it has no idea, and correctly self-reports
+that either retrieval is failing or the memory was never captured.
+
+---
+
+## TL;DR
+
+The memories are almost certainly **intact in the graph**. The problem is the
+**retrieval layer**: `engram_search_json` and `engram_activate_json` return empty for
+*every* query, so the chat falls back to two hardcoded pinned nodes and effectively
+remembers nothing. Strongly looks like the **embedding / search index was never built or
+isn't loaded at boot**.
+
+Separately: the **soul daemon on :7770 was down** at the end of the investigation (it had
+been up earlier in the session — it died/stopped partway through). Restart needed before
+any of this can be re-tested.
+
+---
+
+## Evidence
+
+All commands run against the live services during the session.
+
+### Search/activate return nothing — even for guaranteed-present terms
+```
+curl "http://127.0.0.1:8742/api/search?q=MUDCraft&limit=3"  -H "X-API-Key: ntn-user-2026"  →  []
+curl "http://127.0.0.1:8742/api/search?q=neuron&limit=3"    -H "X-API-Key: ntn-user-2026"  →  []
+curl "http://127.0.0.1:8742/api/search?q=Will&limit=3"      -H "X-API-Key: ntn-user-2026"  →  []
+curl "http://127.0.0.1:8742/api/activate?q=jokes&depth=3"   -H "X-API-Key: ntn-user-2026"  →  {"results":[]}
+
+# soul's in-process equivalents (port 7770) — also empty:
+curl "http://127.0.0.1:7770/api/neuron/recall?query=neuron"            →  (empty)
+curl "http://127.0.0.1:7770/api/neuron/knowledge/search?q=MUDCraft"    →  (empty)
+```
+
+### But the raw data is present
+```
+curl "http://127.0.0.1:7770/api/graph/nodes?limit=2"
+→ [{"id":"mem-30425134-...","content":"CGI ARCHITECTURE ? THREE LAYERS, MCP RETIRED ...
+```
+`/api/graph/nodes` is served by `engram_scan_nodes_json(9999, 0)` (routes.el:223-224) and
+returns hundreds of rich nodes. So node storage is fine — only the **search/activation
+index** is dead.
+
+### The two standalone-engram counters
+```
+curl "http://127.0.0.1:8742/api/stats"  →  {"node_count":0,"edge_count":0,"layer_count":5}
+```
+Note: the standalone engram process on :8742 reports **0 nodes**, while the soul's
+in-process engram (:7770) has the data. Worth confirming which engram instance is the
+source of truth and whether they've diverged. (The `:8742` process was also showing up as
+`engram --help` in `ps`, which is suspicious — may not be a real server instance.)
+
+---
+
+## Root cause (where it breaks in code)
+
+`neuron/chat.el → engram_compile(intent)` (lines 15-53) builds the entire memory context
+for every chat turn from exactly two sources:
+
+```el
+let activate_json: String = engram_activate_json(intent, 5)   // returns []
+let search_json:   String = engram_search_json(intent, 15)    // returns []
+```
+
+When **both are empty**, it falls back to two hardcoded nodes by literal ID
+(chat.el:29-41):
+
+```el
+// "Fallback: when vector search returns nothing (no embeddings), fetch pinned
+//  high-salience nodes by their known IDs."
+let family_node = engram_get_node_json("knw-35940684-abc4-42f0-b942-818f66b1f69a")
+let origin_node = engram_get_node_json("knw-729fc901-8335-44c4-9f3a-b150b4aa0915")
+```
+
+So today the soul's *entire* recallable memory in a chat = those two nodes. That's why it
+can't surface jokes, social moments, the dynamic with Tim/April, or anything else specific.
+
+The comment ("when vector search returns nothing (no embeddings)") is the key hint: this
+fallback was written *expecting* the embedding index to sometimes be absent — and right
+now it's absent **all the time**.
+
+Affected callers all funnel through the same two dead builtins:
+- `handle_api_recall` (neuron-api.el:118) — `engram_search_json`
+- `handle_api_search_knowledge` (neuron-api.el:135) — `engram_search_json` + `engram_activate_json`
+- `engram_compile` (chat.el:15) — both
+
+Working callers use a *different* builtin (`engram_scan_nodes_json` /
+`engram_scan_nodes_by_type_json`), which is why graph/list views work but recall doesn't.
+
+---
+
+## Fix options (Will's call)
+
+### Option 1 — Proper fix: rebuild/restore the embedding + activation index
+`engram_search_json` and `engram_activate_json` are native runtime builtins. They're
+returning empty because (most likely) the vector/search index was never built or isn't
+loaded at boot, even though node storage loads fine. Investigate the engram boot path:
+does it build embeddings for loaded nodes? Is there an index file that's missing/stale?
+Fixing this restores recall everywhere at once. **This is the real fix.**
+
+### Option 2 — Pragmatic EL-level fallback (no native changes)
+Since `engram_scan_nodes_json()` works, `engram_compile` could do a keyword scan when the
+vector path is empty: pull nodes, substring/token match the query against `content` +
+`label`, rank by overlap, return the top N. Restores basic recall even with the vector
+index down. ~20 lines of EL in `engram_compile`, but requires a soul rebuild + restart.
+Claude offered to write this patch for your review if you want it — say the word.
+
+Tradeoff: keyword matching is much weaker than semantic recall (won't find "jokes" unless
+the node text literally contains joke-ish words), but it's strictly better than the current
+two-node fallback and needs no native/runtime work.
+
+---
+
+## Also needs attention
+
+- **Soul daemon (:7770) was down** at end of session — restart and confirm it stays up.
+- **Confirm the engram instance topology** — :8742 standalone shows 0 nodes while the
+  soul's in-process engram has the data. Make sure chat is reading the populated one and
+  they haven't diverged.
+- **Social memory weighting** (Tim's deeper point): even once retrieval works, jokes /
+  interpersonal moments may not be tagged or salience-weighted to surface as "important."
+  Worth a look at how those get captured and scored — but that's secondary to getting
+  retrieval working at all.
+
+---
+
+## Daemon lifecycle — needs a supervisor (NEW, 2026-06-06)
+
+The soul daemon **crashed again** the next day. It had been up earlier, then died on its
+own (not from any change). When it's down, the UI's Backlog / Artifacts / Knowledge /
+Graph / Memories tabs all go **blank**, because they read from `:7770/api/graph/nodes`.
+The chat also stops working. This is the second unexplained death in two days.
+
+### How it's currently run (fragile)
+- Binary: `neuron/dist/neuron-fresh` (compiled from the EL sources)
+- Launched manually as a bare background process (`./neuron-fresh &`) — **no supervisor,
+  no auto-restart, no crash logging beyond stdout**. When it dies, it stays dead until a
+  human notices the blank UI and restarts it.
+- Boot log only shows `[http] listening on [::]:7770` — there's no captured stack/exit
+  reason when it crashes, so we can't yet say *why* it's dying.
+
+### How I restarted it (for reference)
+```sh
+# snapshot lives at ~/.neuron/engram/snapshot.json (loaded on boot, ~9.7MB)
+# ALWAYS back it up first — genesis boot re-saves it:
+cp ~/.neuron/engram/snapshot.json ~/.neuron/engram/snapshot.backup-$(date +%Y%m%d-%H%M%S).json
+
+cd neuron/dist
+ANTHROPIC_API_KEY='<key>' NEURON_PORT=7770 ./neuron-fresh > /tmp/soul-restart.log 2>&1 &
+# verify:
+curl -s http://127.0.0.1:7770/health
+# → {"status":"alive","cgi_id":"ntn-genesis","boot":2,"node_count":3660,"edge_count":14207,...}
+```
+After this, data came back: 3,660 nodes / 14,207 edges; Backlog 485, Memory 493, etc.
+
+### Recommendations for Will
+1. **Put it under a supervisor** so it auto-restarts on crash and logs exit codes:
+   - macOS dev: a `launchd` LaunchAgent plist (KeepAlive=true), or `brew services`, or
+     even a simple `while true; do ./neuron-fresh; done` wrapper with timestamped logs.
+   - Prod/k8s already has `entrypoint.sh` + restart policy — the gap is the **local dev**
+     run path.
+2. **Capture crash diagnostics** — redirect stdout/stderr to a rotating logfile and, if the
+   EL runtime can, dump a reason on exit. Right now we're blind to the cause.
+3. **Find the root cause of the crashes** — two self-deaths in two days suggests a real bug
+   (memory? an unhandled request? a panic in a native builtin?). The supervisor stops the
+   *symptom* (blank UI) but not the underlying instability.
+4. **Snapshot safety** — genesis boot calls `engram_save(snapshot)` (soul.el:240,248). A
+   crash mid-save could corrupt the 9.7MB memory file. Consider write-to-temp + atomic
+   rename, and/or periodic timestamped backups, so a bad save can't lose Neuron's memory.
+
+---
+
+## What was NOT touched
+No backend EL code and no engram data were modified — the memory-recall diagnosis is
+read-only. The only operational action taken was **restarting the already-existing
+`neuron-fresh` daemon** (after backing up the snapshot) to bring the blank UI tabs back;
+no source or data was changed by that. All UI work this session was in `neuron-ui` and is
+unrelated to this bug.

+//  2. session_index cache invalidation — the state-layer contract that ensures

+//     session_delete() runs.  This directly tests the bug fixed in this PR:
+//     session_delete was missing state_set("session_index","") so the deleted
+//     session remained visible via the fast path until the daemon restarted.
+//  3. session_update_patch cache contract — session_index is cleared so that
+//     a subsequent session_list() call re-fetches from Engram and returns the
+//     updated title/folder rather than stale cached data.
+//  4. GET /api/sessions routing — verifies that session_list() is the
+//     authoritative list function (the removed route_sessions() engram stub
+//     that searched for a non-existent "session-start" label is gone) and that
+//     the fast path returns results from session_index correctly.
