 ## [Unreleased]
 
+## [0.462.0] - 2026-10-13
+### Security
+- **An agent's shell can no longer read the tenant DB, the connector bag, the vault key or other
+  sessions' transcripts.** The protected-path check only ever covered the Read/Glob/Grep tools, and an
+  agent runs as the same OS user as the server, so Bash reached all of it. Replaying 30 days of real
+  commands showed this was routine, not a one-off. On expresstech, agents ran `sqlite3`/`node:sqlite`
+  on `agent-os.db` 34 times, scraped `FREESCOUT_API_KEY` out of other sessions' `connectors/*.mcp.json`,
+  and grepped `~/.claude/projects` for other agents' transcripts. A new engine-level check
+  (`governance/protected-read.ts`, folded in with `stricterDecision` on every tenant whatever its policy)
+  denies a shell call that names one of these paths in the command line, a heredoc or `-e` body, or a
+  script the command runs. It also catches relative paths through the agent folder or a `cd`, `~` and
+  `$HOME` forms, globs, the DB's WAL sidecars, and recursive readers pointed at an ancestor. It covers the
+  OS's own state (the DB, `secret.key`, `connectors/`, `control/`, `tenants/`, pooled
+  `runtime-accounts/`, `claude-config/`), `~/.claude/projects` and the Claude/Codex logins. It
+  deliberately does NOT cover `~/.ssh`/`~/.aws`, which infra agents use by design through ssh and the
+  CLIs. An agent's own transcript folder, Claude Code auto-memory and skill/plugin folders stay readable.
+  The deny message points at the governed tools (`session_history`, `secret_get`/`secret_request`).
+  The policy preview gives the same answer, and `secret.key` joins the Read tool's list, where it was
+  missing. Pattern-matching can't stop a deliberately obfuscated path; real containment is
+  `AOS_UID_ISOLATION`.
+- **Login session ids and magic-link tokens are stored hashed.** `auth_sessions.sid` was the `aos_sid`
+  cookie verbatim, so reading the DB meant signing in as any member, owners included. Both are now stored
+  as a SHA-256 (`h1:` tag). The migration hashes existing rows in place, so cookies and links already
+  handed out keep working.
+  **For admins:** agents that read the workspace database, other sessions' files or connector configs from
+  the shell are now refused and steered to the built-in tools. If an agent's instructions tell it to run
+  `sqlite3` on `agent-os.db`, update them to use `session_history`, the task tools or `secret_request`.
+
 ## [0.461.2] - 2026-10-13
 ### Fixed
 - **Session search's transcript indexer no longer stalls the server on long transcripts.** v0.461.0

   Deliberately NOT `disableRemoteControl` (which kills the feature outright): a human attached in the
   browser terminal can still type `/rc` on purpose. Same undeclared-input class as the `~/.claude` note
   below.
+- **An agent's SHELL can read anything its OS user can — so the tenant DB and every transcript are
+  guarded by INTENT, not by the filesystem.** The Read/Glob/Grep arm of the gate hook (`AOS_PROTECTED_PATHS`)
+  never covered Bash; `src/governance/protected-read.ts` (v0.462.0) now denies a shell call that names the
+  DB, `secret.key`, `connectors/`, `control/`, `tenants/`, `runtime-accounts/`, `claude-config/`,
+  `~/.claude/projects` or a runtime login — in the command, a heredoc/`-e` body, or a script it runs — and
+  login cookies/magic-link tokens are stored hashed (`tokenAtRest`), so a read that slips past can't sign
+  anyone in. Replaying a live tenant's commands showed agents doing this ROUTINELY (DB queries, scraping API
+  keys out of other sessions' `connectors/*.mcp.json`), so expect denials where a prompt relied on it.
+  `~/.ssh`/`~/.aws` are deliberately NOT in the shell list (infra agents use keys by design). Obfuscation
+  beats any intent check; the real wall is `AOS_UID_ISOLATION`.
 - **The box owner's `~/.claude` is an undeclared input to every agent.** A session runs as the same OS user
   as the human who owns the machine, so it loads their user-scope `settings.json` — `enabledPlugins` above
   all, which drags in a plugin's subagent types, skills, slash commands and **SessionStart prompt hooks**.

+ * PROTECTED-PATH GUARD FOR THE SHELL — engine-level, like the file-write guard beside it.
+ * Covers the OS's own state and every session's transcript (see `protectedRoots` for exactly what, and
+ * why it is narrower than the Read tool's list).
+ *
+ * The crown-jewel READ protection lived only in the gate hook's Read/Glob/Grep arm (`AOS_PROTECTED_PATHS`).
+ * Bash was never covered, and an agent runs as the same OS user as the server, so the filesystem doesn't
+ * stop it either. The case that surfaced it (expresstech, 2026-10-12): asked to find a past session, a
+ * researcher agent wrote a script that opened the tenant DB with `node:sqlite` and grepped
+ * `~/.claude/projects` for other agents' transcripts — reading, along the way, a table of login cookies.
+ *
+ * This is an INTENT check over what the command says, not a wall: it denies the shapes an agent actually
+ * types — a protected path named in the command line, in a heredoc or `-e` body, or in a script the
+ * command runs; a relative path that resolves into one from the agent's folder or a `cd` target; a
+ * recursive reader pointed at an ancestor of one. A deliberately obfuscated path (built from pieces,
+ * base64, a glob that only expands at run time) gets past it; the real containment for that is the
+ * Linux per-member uid isolation (`AOS_UID_ISOLATION`), and the worst payload in the DB — the login
+ * session ids — is stored hashed (team.ts) so a read that does get through can't sign anyone in.
+ *
+ * Folded into the policy verdict with `stricterDecision`, so it reaches every tenant regardless of a
+ * persisted policy override, and can only tighten.
