Both are shared memory. **Scope** of shared memory is the repository: every worktree and every subdirectory launch of one repository shares one memory. Outside a repository the scope is the directory the agent was started in. +Every write to an entry is a **revision**: immutable, sealed into a hash chain, and the canonical record; the entry is the current view of its revisions (ADR-0017). An entry's **state** is **active** (briefed and searched), **candidate** (captured or imported, not confirmed: never briefed until an agent restates it or the user approves it) or **archived** (dismissed, wrong, superseded or expired: kept in history, out of briefings and default search). A keyed replace of another writer's entry needs the **expected revision** it read. + +An entry may carry **evidence**: **citations** of code lines, hashed by the server and checked at every read, giving its **validity** — valid, moved, stale or unverifiable (ADR-0018). An uncited decision, fact or architecture note may instead get **commit evidence** from the session recorder: the commits that carried its writing turn's files, stale only when every file lost that work. A stale memory leaves the briefing. + +Each finished session leaves a **handoff note**: what it planned and left open, decided, found failing and changed, plus — when the session recorder captured it — what it actually did (files written, failed tool calls, commits, an interrupted last turn). The next agent's briefing carries the newest one from another session. The **review queue** (Memory ▸ Shared ▸ Review) holds candidates, **merge proposals** (near-duplicates), **contradictions** (pairs linked `contradicts`) and the **dream** pass's proposals; nothing in it changes memory until the user acts. + Shared memory also records **session lifecycle** (session start and end, todo added and done, and which agent owns each session). Lifecycle is bookkeeping for the record, never something an agent is shown. Terms that are *not* shared memory: **capture** (raw transcripts, see Timeline), **knowledge notes** (user-written pages in the Knowledge panel), the **codebase index** (derived from source), and any agent's own memory files (`CLAUDE.md`, `AGENTS.md`, Claude's auto-memory directory). These may be *sources* shared memory cites or imports, but an entry in them is not an entry in shared memory. -Shared memory reaches an agent one way only: it **pulls** it through the **memory tool server**, the in-process MCP server Atlas hands every session that can take it (ADR-0010). Nothing is prepended to a user's message; the text goes to the agent exactly as typed. The server's **instructions** are the protocol — read first, write as you learn — and its tools are, in that order: **`memory_briefing`** (the first look of a session: working memory, the **durable index**, the **curated pack** and the **recent-session handoff**), **`memory_changes`** (what *other* sessions recorded since this session's **last look**), **`memory_search`** (the record plus the codebase index's documents), **`memory_get`**, **`memory_list`**, **`memory_remember`** and **`memory_forget`**. +Shared memory reaches an agent one way only: it **pulls** it through the **memory tool server**, the in-process MCP server Atlas hands every session that can take it (ADR-0010).

An agent without HTTP MCP reaches the same server through the **stdio bridge**, the Atlas binary run as `atlas mcp-bridge` (ADR-0019). - The **durable index** is one capped line per durable entry, each kind's best up to its display cap, ranked by recency (two-week half-life), use count and confidence; `memory_get` expands a line. It lists shared-memory entries; it is not the codebase index, and not the retrieval index `memory_search` also searches. - The **curated pack** is the high-signal part of the project's foreign memory files (Claude's memory directory, `CLAUDE.md`, `AGENTS.md`), recency-ranked and budget-bounded. The **recent-session handoff** is the tail of the most recent other session in the scope, whichever agent ran it, read from capture (or, where capture was never enabled, from Atlas's own session transcripts) — never from an agent's own files. diff --git a/Cargo.lock b/Cargo.lock index ada33778e..03a23a1f1 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -3338,6 +3338,8 @@ dependencies = [ "atlas-embed", "atlas-profile", "atlas-redact", + "atlas-retrieval", + "blake3", "chrono", "rusqlite", "serde", diff --git a/crates/atlas-agent-servers/src/lib.rs b/crates/atlas-agent-servers/src/lib.rs index 33605cd0a..1ab9498b3 100644 --- a/crates/atlas-agent-servers/src/lib.rs +++ b/crates/atlas-agent-servers/src/lib.rs @@ -77,8 +77,9 @@ pub use debug_log::{ pub use handlers::ClientContext; pub use host_env::sanitize_host_env; pub use server::{ - env_quirks, env_quirks_from, load_proxy_env, AgentServer, AgentServerDelegate, ConnectOptions, - CustomAgentServer, ExternalAgentServer, + atlas_only_memory, env_quirks, env_quirks_from, load_proxy_env, memory_quirks, + set_atlas_only_memory, AgentServer, AgentServerDelegate, ConnectOptions, CustomAgentServer, + ExternalAgentServer, }; pub use session::{ AcpSession, CancelProbe, CancelSignal, CancelWaiter, ConfigOptions, SessionDirectories, diff --git a/crates/atlas-agent-servers/src/server.rs b/crates/atlas-agent-servers/src/server.rs index 723d5a6ba..b706ec81c 100644 --- a/crates/atlas-agent-servers/src/server.rs +++ b/crates/atlas-agent-servers/src/server.rs @@ -186,12 +186,14 @@ impl AgentServer for CustomAgentServer { Box::pin(async move { let mut extra_env = load_proxy_env(); extra_env.extend(env_quirks(&agent_id)); + let (memory_env, memory_args) = memory_quirks(&agent_id, atlas_only_memory()); + extra_env.extend(memory_env); let server = delegate .server .clone() .ok_or_else(|| anyhow::anyhow!("no command resolver for agent `{agent_id}`"))?; - let command = server.get_command(Vec::new(), extra_env).await?; + let command = server.get_command(memory_args, extra_env).await?; let connection = AcpConnection::stdio( agent_id, @@ -249,6 +251,52 @@ pub fn load_proxy_env() -> HashMap { env } +/// Whether Atlas's shared memory is the only memory in Atlas sessions (the +/// `atlasOnlyMemory` setting, default on).

A parallel session of the same agent (another worktree) is another writer. The refusal names the revision and tells the agent to read both versions and write one that keeps what is still true. +- **Projections are rebuilt from canonical data.** `entries_fts` (BM25) is rewritten in the same transaction as its entry. Vectors are cached by `(model, text)` in `embed_cache`, so a vector can never describe text it was not computed from, and switching back to an earlier model re-embeds nothing. The corpus index is `corpus.sqlite` plus a per-model vector file that is rebuilt from the cache whenever it is missing, torn or out of step, without the model. +- **Only `clear` and `purge` delete revisions.** `clear` is the user's confirmed wipe. `purge` erases a forgotten secret from the revisions, the event log and the vector cache, with SQLite's secure delete on and the WAL truncated, and leaves one textless `purge` marker. A test counts the statements that delete revisions. +- **Revisions are sealed into a hash chain.** Each revision's `chain` is blake3 of the previous revision's chain and this row's columns. The chain is unkeyed: it catches hand edits, `sqlite3` one-liners and scripts that write rows directly, not a tool that recomputes it. Purge re-seals from the first revision it removed.

When the session recorder (`atlas-checkpoint`) captured the writing session, it knows which files that turn wrote (with a line fingerprint taken at write time) and which commits carried them. + +## Decision + +- **Citations are server-hashed.** `memory_remember` takes `evidence: [{path, lines, symbol?}]`. The server reads the lines from disk, refuses a path outside the scope root or a missing file, and stores the hash. An agent never supplies a hash. At most 8 citations, 200 lines each. +- **Every read checks.** `memory_get`, `memory_list`, `memory_search`, `memory_briefing` and the `memory_remember` result carry `validity` (`valid`, `moved`, `stale`, `unverifiable`) and the citations as found now. A citation is `valid` when the exact lines still hash the same, `moved` when the symbol's current span (through the open code index) or any same-length window of the file does, and `stale` otherwise. A file too large, binary or unreadable is `unverifiable`. +- **Stale memories leave the briefing and sink in search.** The briefing counts them in `staleHidden`; search keeps them after every memory that holds. +- **Commit evidence for uncited memories.** A decision, fact or architecture note with no citation is matched to the recorded turn it was written in. If that turn's files reached a commit, the memory carries `commits` and a validity from whether the files still hold the agent's work (the link rule's 50 % line containment), with `validityFrom: "commits"`. It is stale only when every landed file lost that work. A commit being orphaned (a squash merge) decides nothing. Citations, when present, decide alone. +- **Expiry.** A health pass archives a candidate nobody wrote or used for 28 days, and an active memory unused for 28 days only when its citations are stale. An active memory without citations never expires on time alone. + +## Consequences + +- Reads stay cheap: results are cached by file size and mtime, commit evidence is checked for at most 300 entries per read, and both caches are bounded. +- Extracted and captured memories have no citations; they get commit evidence when capture recorded the session, and nothing otherwise. +- A moved symbol is found by the code index when one is open for the scope, else by a same-length window search of the file. +- Commit evidence is computed at read time and stored nowhere: a rebase that re-points a commit, or a capture store that is deleted, changes the answer without a migration. +- Archiving is a revision (ADR-0017), so a restatement by another session revives an archived memory. diff --git a/docs/adr/0019-a-stdio-bridge-carries-memory-to-agents-without-http-mcp.md b/docs/adr/0019-a-stdio-bridge-carries-memory-to-agents-without-http-mcp.md new file mode 100644 index 000000000..f702ef270 --- /dev/null +++ b/docs/adr/0019-a-stdio-bridge-carries-memory-to-agents-without-http-mcp.md @@ -0,0 +1,27 @@ +# ADR-0019: A stdio bridge carries memory to agents without HTTP MCP + +**Status:** Accepted (2026-10-07).

A JSON-RPC error goes back to the agent instead of ending the bridge. +- When the server no longer knows the session (a 404 that is not JSON-RPC), the bridge replays the agent's `initialize` and `notifications/initialized`, takes the new session id and retries the request once. The memory and code servers also keep idle sessions (no keep-alive timeout), so an agent that goes quiet for a while keeps its tools. +- The token is passed in the environment variable `ATLAS_MCP_TOKEN`, never in argv (argv is visible to other users through `ps`).
