dtoro 926969a03f fix(agent): live chat turns persist incrementally, survive client disconnect
Fix A3 of plans/2026-07-11-nomos-agent-code-review.md. handleChat only ever
saved the assistant message ONCE, after a.chat(...) returned, using
ctx := r.Context() for that write — the same context that cancels the instant
the client disconnects (Stop button, tab close, network blip). A disconnect
mid-turn meant the final save ran with an already-cancelled context and its
error was never checked: the entire turn's tool-call history was silently
lost from the persisted transcript, even though real work (executions
launched, knowledge written) had already happened server-side.

Brought handleChat in line with resumeSession's existing pattern
(continue.go): insert a placeholder assistant row immediately, update the
SAME row after every tool call. The key fix is WHICH context the writes use —
a new pctx := context.Background() for every DB write in this handler
(session creation/touch, the user message, question auto-close, the
placeholder + incremental updates, the title update), while ctx/r.Context()
still gates the agent's own work (a.chat) and the SSE writes exactly as
before — a disconnect still correctly stops the agent from doing further
work, it just no longer also erases what it already did.

Verified live: sent a message requiring 6 tool calls (get_entity/
get_relations/get_blast_radius on two targets) and force-killed the client
connection mid-stream with curl -m 12 (confirmed via exit code 28). Before
this fix the persisted transcript would show 0 tool-call entries; after,
all 12 raw tool_use/tool_result entries (6 calls × 2) were present and
correctly attributed by tool name — proving both that progress survives an
abort and that the incremental writes aren't corrupting the data.

Oikos

Agentic homelab operating system written in Go. Single binary (cmd/oikos), Docker-deployed on mac-mini, with a standalone Nomos MCP agent gateway (cmd/nomos). Manages the hubris Proxmox homelab autonomously — observes state, classifies actions against policy, executes approved procedures over SSH, learns from outcomes, and escalates when uncertain.

For agents running on enrolled clients: start with AGENTS.md. For client machines: see CLIENTS.md. For developers: see CONTRIBUTING.md.

Quick start

# Dev stack (postgres + api + scheduler + notifier)
docker compose --profile dev up -d

# Full stack (adds Nomos agent gateway)
docker compose --profile full up -d

# Build standalone binary
go build -o bin/oikos -tags timetzdata ./cmd/oikos

# Run all roles in one process (dev mode)
OIKOS_DATABASE_URL="postgres://oikos:oikos_dev@localhost:5432/oikos?sslmode=disable" \
  go run ./cmd/oikos all

For agents

See AGENTS.md for the full orientation. Quick reference:

  • Source of truth: DB (runtime) then seeds (bootstrap). Old wiki is archived at archive/knowledge/ — use MCP search_knowledge instead.
  • Mutations: classify against policy, request approval for destructive/config_mutation
  • Secrets: Infisical (primary) or SOPS (fallback) — never hardcode
