 # ACP Runtime State Contract
 
 This directory owns the boundary between durable ACP agent configuration and
-process-local agent state. Keep the boundary profile-driven. The launcher must
-not grow agent-name conditionals when a new ACP agent is added.
+process-local agent state. ACP is the generic channel for custom,
+user-supplied agents speaking the Agent Client Protocol; the only registered
+profile is the generic `acp` profile (managed launch `command`/`arguments`,
+`api_key` setup mode). Built-in External Agents (Codex, Claude Code) are not
+ACP profiles — they run as direct external runtimes under
+`internal/agent/runtime/codex` and `internal/agent/runtime/claudecode`.
+
+Keep the boundary profile-driven. The launcher must not grow agent-name
+conditionals.
 
 ## Required invariants
 
-- Every ACP process receives a fresh, mode-specific runtime directory under
-  `/tmp/memoh-acp-runtime/<agent>/<uuid>` with mode `0700`.
-- Never put an agent's complete home on `/data`, and never symlink a runtime
-  home back to `/data`.
-- Stage only paths declared by the agent profile. Locks, SQLite/WAL files,
-  sockets, PIDs, and caches stay process-local. Supported JSONL session trees
-  are the one exception: Memoh may reconstruct them from its fenced PostgreSQL
-  snapshot inside the new UUID runtime, but they never round-trip through
-  `/data` or the ordinary durable-artifact synchronizer.
-- `/data` may contain only profile-declared configuration and credentials.
-  Managed Codex and Hermes files remain durable and are staged into each
-  RuntimeLease; their locks, databases, sessions, and caches never are.
+- Every ACP process receives a fresh runtime directory under
+  `/tmp/memoh-acp-runtime/<agent>/<uuid>` with mode `0700`. It holds only
+  ephemeral state (`TMPDIR`) and is removed when the process exits.
+- The agent's durable state lives directly under `HOME=/data` (the workspace
+  volume). Memoh stages nothing into the runtime directory and syncs nothing
+  back out of it; the agent owns its own files on `/data`.
+- Never symlink a runtime path back to `/data`.
 - Cleanup may remove only the UUID directory owned by that process. Startup
   failure, natural process exit, and explicit `Close` use the same finalizer.
-- A failed durable sync preserves the UUID directory for manual recovery.
-- Runtime files never delete durable files. Durable writes are atomic and must
-  either use compare-and-swap or an agent-specific monotonic freshness rule.
-- Adapter-native session state is one line set per session plus small
-  run-versioned headers, guarded by the same Bot -> Session PostgreSQL
-  runtime-fence transaction used by chat persistence. Each header carries its
-  version's per-file shapes (record count + content digest); staging appends
-  only a file's tail after proving the stored canonical prefix is
-  byte-identical (a running digest snapshotted at the previous head's record
-  count). Staging and publication commit in different transactions, so while
-  a canonical checkpoint exists no statement may touch a row it references:
-  a capture whose canonical files cannot be proven byte-identical prefixes
-  (rewritten, shortened, or removed) DECLINES staging entirely, the turn
-  publishes an explicit reset, and only once that reset is canonical may the
-  next turn stage a full rewrite. A version is load-visible only when its run
-  owns the session's canonical publication head (`acp_session_publications`),
-  which is committed in the same transaction as the round's messages; readers
-  bound every file by the head version's shape (so a crashed candidate's
-  dangling tail is invisible) and verify each file's content digest, failing
-  closed instead of restoring silently wrong context. The database head is the
-  single authority: a warm process records the head its native conversation
-  corresponds to and compares it against the durable head before every prompt
-  — there is no in-memory publication handshake to resolve. Store each JSONL
-  record as verbatim compacted text and reject absolute, traversing,
-  undeclared-root, symlinked, or non-JSONL paths. A stale runtime must never
-  stage a newer candidate.
-- The head only advances when the native runtime actually advanced: a staged
-  snapshot publishes a resumable checkpoint, a snapshot-incapable completion
-  publishes an explicit reset, and a user-aborted turn publishes nothing — the
-  warm runtime stays reusable and a cold start resumes the last complete turn.
-- JSONL persistence promises byte equality across the database round trip:
-  records are stored as verbatim compacted TEXT (never JSONB, whose key-order,
-  whitespace, and number normalization would silently break every digest the
-  append-only proof and load verification depend on). Keep explicit
-  file/record/byte budgets and batch inserts; never aggregate an entire
-  transcript into one PostgreSQL datum.
-- A stable filesystem snapshot is not by itself fresh. After each successful
-  prompt, the agent-specific durable proof must match before the candidate can
-  be staged: Codex's terminal turn cursor must advance; Claude Code must run
-  with eager transcript flushing and every UUID in that prompt's raw SDK
-  user/assistant/result receipt must match the stable JSONL snapshot (aborted
-  assistant records are never publishable).
 - Below writable roots such as `/tmp`, inspect every existing path component
   before creating the next one and immediately recheck each created directory.
   Never call recursive mkdir on an unvalidated runtime or cache parent.
-- Codex `auth.json` writes are ordered by its RFC3339 `last_refresh` value. A
-  stale process must never overwrite a newer process or OAuth-handler token.
-  Synchronize after each prompt and periodically while the process is alive.
-- Sync cadence is deliberately asymmetric. Only `codex_auth` artifacts get the
-  live per-prompt/periodic sync above; every `compare_and_swap` artifact
-  (Claude Code and Hermes configuration and credentials, Codex self-mode
-  trees) writes back only at process exit. A server- or container-level kill
-  before exit loses agent-side changes from that session — CAS still
-  guarantees the durable copy is never corrupted or replaced by stale data.
-  This is the documented degraded tier: extending live sync to another agent
-  requires a per-file freshness rule like Codex's, not a cadence change alone.
+  Pre-planted symlinks under `/tmp` (runtime and shared-cache tiers) must fail
+  the lease with no side effects at the symlink target.
+- Conversation continuity is Memoh's context document. Every ACP session
+  starts fresh; each completed turn publishes an explicit reset head
+  (`agent_session_publications`) in the same transaction as the round's
+  messages. The durable head is the single authority: a warm process records
+  the head its native conversation corresponds to and compares it against the
+  durable head before every prompt, so a session advanced elsewhere is
+  restarted instead of silently diverging.
+- Process preparation runs under the bot's runtime-configuration guard
+  (`RuntimeSyncGuard`): a stale configuration generation or an in-progress
+  reset must not start a new runtime.
 
 ## Profiles
 
-`profile.RuntimeStoragePolicy` is the source of truth. Each supported setup
-mode must declare:
-
-- agent process environment bindings;
-- files or trees staged from `/data`;
-- whether each staged artifact is read-only, compare-and-swap durable, or uses
-  a specialized freshness strategy;
-- files generated directly in the RuntimeLease by Memoh; and
-- process-local JSONL roots eligible for database snapshot and restore.
-
-Use the narrowest state variable supported by the pinned agent. Keep
-`HOME=/data` when that variable covers all agent state; Hermes also receives a
-runtime-local `HOME` because its pinned release still uses home-relative auth
-paths.
-
-| Agent | Process-local state variable | Managed durable data | Database resume root |
-| --- | --- | --- | --- |
-| Codex | `CODEX_HOME` and `CODEX_SQLITE_HOME` | allowlisted `auth.json` and `config.toml` | `state/sessions` |
-| Claude Code | `CLAUDE_CONFIG_DIR` | none; managed credentials use process environment | `state/projects` |
-| Hermes | `HERMES_HOME` | managed `config.yaml` and `.env` | none |
-
-Hermes is the degraded tier. Its runtime-local `HOME` is ephemeral by design:
-`$HOME`-relative files written by the agent or its subprocesses do not survive
-the process; only explicitly allowlisted `HERMES_HOME` paths round-trip to
-`/data`.
+`profile.RuntimeStoragePolicy` is the source of truth. Each profile declares
+its launcher-owned environment bindings (`HOME=/data`, runtime-local `TMPDIR`,
+shared `NPM_CONFIG_CACHE`) and the setup modes allowed to start a process.
 
 The ACP terminal/tool environment is separate from the agent environment. Its
 working directory and `HOME` remain under `/data`; do not expose the agent's
-temporary home to ordinary workspace commands. Preserve the existing
-`CleanEnv` and `UnsetEnv` credential filtering.
+runtime directory to ordinary workspace commands.
 
 Shared package caches may live under `/tmp/memoh-acp-cache`. They must remain
 container-local and contain no credentials or mutable agent session state.
 
-## Version and file audits
-
-Built-in profiles launch the adapter binaries pinned by
-`docker/toolkit/install.sh`; they must not resolve npm `latest` at runtime.
-Before changing an allowlist, inspect the exact pinned adapter and agent source
-to confirm:
-
-1. the state/config environment variable it honors;
-2. every credential or user-authored configuration path;
-3. how it launches shell subprocesses; and
-4. which files are locks, databases, sessions, histories, or caches.
-
-Do not infer filenames from another release and do not allowlist an entire
-agent home as a shortcut. Mixed config/state files, such as Claude Code's
-`.claude.json`, require an explicit read-only or field-aware decision.
-
 ## Verification
 
 Behavior-level coverage should include:
 
-- all built-in profiles and setup modes pass policy validation with no path
+- the generic profile and its setup modes pass policy validation with no path
   escape;
-- consecutive processes get different runtime roots and never see each
-  other's locks or databases;
-- only allowlisted configuration survives close;
-- stale Codex OAuth copies cannot replace newer durable credentials;
+- consecutive processes get different runtime roots;
 - startup failure removes its runtime root without changing `/data`;
-- only profile-declared managed configuration and credentials appear on
-  `/data`;
-- ordered multi-file JSONL snapshots round-trip through the database, resume
-  with the same adapter session ID, and never replay load history as a new
-  turn;
-- stale fences, path traversal, symlinks, malformed JSON, profile/cwd changes,
-  and deliberately fresh discuss runtimes cannot overwrite or consume a normal
-  resumable snapshot;
-- pre-planted symlinks under `/tmp` (runtime and shared-cache tiers) fail the
-  lease with no side effects at the symlink target;
-- container replacement preserves durable config but not runtime state.
+- pre-planted symlinks under `/tmp` fail the lease with no side effects;
+- a completed prompt records a reset publication head under the round's fence;
+- a legacy checkpoint head found on cold start logs a warning and starts a
+  fresh session.
