wait_ready ran the rpc health probe inside a `vim.wait` predicate, and the probe
itself uses `vim.wait` — nesting vim.wait inside another vim.wait's predicate
deadlocks Neovim. It only bit when the socket file existed: the first launch's
socket doesn't exist yet (probe short-circuits), but the second launch hit the
stale socket left by the prior daemon and froze in setup().
- wait_ready now probes in a plain Lua loop (deadline via uv.hrtime + a bare
vim.wait(50) yield) — never a vim.wait inside a vim.wait predicate.
- stop_spawned now unlinks the socket on exit, so a clean exit leaves no stale
socket (a crash still can — the wait_ready fix handles that too).
Verified: two-launch repro no longer hangs; a crash-left stale socket recovers
in ~460ms. 10 e2e specs green.

The plugin now manages its own hephd by default (autostart = true): if nothing
is serving the socket it spawns a local daemon against the default XDG paths,
kills only what it spawned on VimLeavePre, and self-heals — rpc.call retries
once through a respawn hook when the connection drops (the prior owner releases
the DB lock on exit, so a respawn can claim it).
- daemon.ensure() connects to an already-running daemon (any mode) or spawns one
we own; stop_spawned()/is_managed() track lifecycle.
- A server/client daemon you started is always respected (spawn only when nothing
serves the socket). autostart = false → connect-only, warns/errors if down,
and clears the self-heal hook so it fails loudly.
- config: autostart defaults true; new `db` option; $HEPH_SOCKET / $HEPH_DB
fallbacks isolate a dev Neovim onto a separate daemon + DB.
e2e: managed_daemon_spec covers autostart spawn, self-heal-after-kill, and
connect-only error. 10 specs green.

The primary surface begins (tech-spec §8): a Neovim plugin that is a thin
client of the local hephd over its unix-socket JSON-RPC.
- node.resolve {title} → Node|null (heph-core Store + dispatch): exact,
owner-scoped, non-tombstoned alias-then-title match — the same mapping that
materializes wiki links, so follow-link jumps to the node the stored link
points at (never fuzzy search). Unit + rpc_socket integration tests.
- heph.nvim/: vim.uv unix-socket JSON-RPC client (blocking call via vim.wait,
id-demuxed, partial-line buffered, luanil so JSON null → Lua nil; isolated
Sessions for tests). Buffer-backed nodes (heph://node/<id>, acwrite;
BufReadCmd→node.get / BufWriteCmd→node.update, whole-buffer body round-trips
exactly through the CRDT). [[wiki-link]] follow on <CR>. Daily journal.
:Heph command surface + completion.
- Headless e2e (§9): a self-contained busted-style runner (tests/e2e/runner.lua)
— no external plugins, no network, deterministic CI exit codes. Specs: journal
round-trip, follow-link (+ unresolved no-op), link-two-docs/backlink.
`make -C heph.nvim test` builds hephd and runs it.
Docs: heph-nvim reference card, §14 tracker (11a done; 11b/11c/11d queued),
