Subject: [PATCH 1/5] feat(auth): add `actual auth create-token` for scoped,
 non-interactive tokens

Add a scoped personal access token (PAT) path so CI jobs and autonomous
agents can authenticate without a browser. `actual auth create-token`
reuses the existing `actual login` session: it loads the stored
credentials, refreshes the access token if needed, calls the authenticated
issuance endpoint, and prints the raw `actl_pat_...` once.

Storage is the OS keychain via the `keyring` crate, with an
XChaCha20-Poly1305 + Argon2id encrypted-file fallback for headless Linux /
CI that has no Secret Service daemon. Non-interactive callers resolve a
token from `ACTUAL_TOKEN`, then the keychain, then the encrypted file. The
raw value is never written to a log or `Debug` output.

`actual auth` keeps its existing runner-auth check when invoked with no
subcommand, so the change is backward compatible.

Proof of concept: the issuance endpoint is developed against the documented
contract and repointed with `--api-url` / `ACTUAL_API_URL` once the server
side ships.

Generated by the operator's software factory.

+# Scoped access tokens for non-interactive use
+
+`actual login` signs you in through the browser. That's fine for a person at a
+keyboard. A CI job or an autonomous agent has no browser to click through,
+though, and that's the gap `actual auth create-token` closes: it mints a
+**scoped personal access token** (PAT) from your existing login session, so
+headless callers authenticate without one.
+
+> **Status: prototype.** This command is a proof of concept. The issuance
+> endpoint it calls is being finalized on the server; the CLI is built against
+> the documented contract and is repointed with a single flag or environment
+> variable once the endpoint ships. See [Endpoint](#endpoint) below.
+
+## Mint a token
+
+```console
+$ actual login                       # once, interactively, in a browser
+$ actual auth create-token --name ci-deploy --scopes adr.read,advisor.read
+✔ Created scoped access token "ci-deploy"
+  Token id:    tok_9f3c
+  Scopes:      adr.read advisor.read
+  Stored in:   OS keychain
+
+Your token is shown once below. Copy it now:
+
+actl_pat_xxxxxxxxxxxxxxxxxxxxxxxxxxxx
+
+Keep this secret safe:
+  • Use a DEDICATED token per agent so actions are attributable and
+    individually revocable; never reuse your interactive login session.
+  • NEVER paste it into a prompt, commit it, or echo it to logs/history.
+  • For CI / non-interactive use, pass it via the ACTUAL_TOKEN env var.
+```
+
+The raw `actl_pat_…` value is printed **once**, to stdout, on its own line, so
+`TOKEN=$(actual auth create-token …)` captures just the secret. After that it
+lives only behind the OS keychain, or the encrypted-file fallback described
+below. It never reaches a log. Copy it now, because there's no second chance to
+read it back out in the clear.
+
+`--name` is required and `--scopes` takes a comma- or space-separated list.
+
+## Two rules for agents
+
+These two rules aren't optional hardening. They're the difference between a
+credential you can reason about and one you can't.
+
+### 1. A dedicated token per agent
+
+Mint a **separate** token for each agent instance, named after that agent
+(`--name <agent>`). Never hand an agent the human's interactive login session.
+
+One token per agent buys two things. Every action an agent takes is attributable
+to that agent's token rather than to a shared identity. And when one agent
+misbehaves or its host is compromised, you revoke that single token without
+disturbing every other agent and every human session.
+
+### 2. The token never enters the model's context
+
+A PAT lives in exactly one of two places. Those are the OS keychain, or the
+`ACTUAL_TOKEN` environment variable for a non-interactive run. It must **never**
+appear in:
+
+- an agent's prompt or conversation context,
+- the shell history,
+- a command-line argument that other processes can read,
+- a log line or an error report.
+
+The failure mode this guards against is specific to agents. An agent reads
+untrusted input: a web page, a file, a tool result. A prompt-injection payload
+hidden in that input can instruct the agent to exfiltrate any secret currently
+in its context. A token that is never in the context cannot be exfiltrated that
+way. Keep the secret in the keychain, or in an environment variable the model
+does not read, and that attack has nothing to reach.
+
+## Non-interactive use
+
+A headless caller resolves its token in this order:
+
+1. the `ACTUAL_TOKEN` environment variable, which is the CI path and needs no
+   storage;
+2. the OS keychain;
+3. the encrypted-file fallback.
+
+```console
+# CI: inject the secret as a masked environment variable, never echoed.
+$ export ACTUAL_TOKEN="actl_pat_…"     # from your CI secret store
+$ actual advisor "why is the build failing?"
+```
+
+In CI, pass the token through the platform's secret store as `ACTUAL_TOKEN`. Do
+not re-mint a token on every run, and do not write it to a file the job logs.
+
+## Storage
+
+```mermaid
+flowchart TD
+    A[create-token mints actl_pat_] --> B{ACTUAL_TOKEN_STORE}
+    B -->|auto default| C[Try OS keychain]
+    B -->|keyring| C
+    B -->|file| F[Encrypted file]
+    C -->|available| D[Stored in keychain]
+    C -->|unavailable, e.g. headless Linux| E{ACTUAL_TOKEN_PASSPHRASE set?}
+    E -->|yes| F
+    E -->|no| G[Error: configure a fallback or use ACTUAL_TOKEN]
+    F --> H[Argon2id key + XChaCha20-Poly1305 AEAD, 0600 file]
+```
+
+The primary store is the OS keychain (macOS Keychain, Windows Credential
+Manager, or the Linux Secret Service), reached through the portable
+[`keyring`](https://crates.io/crates/keyring) crate.
+
+Where no keychain is available, an **encrypted-file fallback** keeps the token at
+rest under the config directory. The file is sealed with XChaCha20-Poly1305,
+keyed by Argon2id over a passphrase read from `ACTUAL_TOKEN_PASSPHRASE`, and
+written `0600`. No passphrase, no fallback. The CLI refuses rather than write
+anything weaker, so a token is never stored in a form softer than the keychain.
+
+| Environment variable | Purpose |
+| --- | --- |
+| `ACTUAL_TOKEN` | A ready-to-use token for a non-interactive run; wins over stored credentials. |
+| `ACTUAL_TOKEN_STORE` | Backend select: `auto` (default), `keyring`, or `file`. |
+| `ACTUAL_TOKEN_PASSPHRASE` | Passphrase that seals the encrypted-file fallback. |
+
+## Headless-storage finding
+
+The question this prototype set out to answer: does the keychain library degrade
+gracefully on a headless Linux box or CI runner that has no Secret Service
+daemon?
+
+The answer is no, and that is the expected, correct behavior. The `keyring`
+crate's Secret Service backend talks to a D-Bus daemon; with no daemon running,
+a store or read returns an error rather than silently dropping the secret or
+inventing a weaker store. Silent degradation is the more dangerous outcome,
+because it leaves a token written somewhere unprotected. An explicit error is
+what you want.
+
+The CLI turns that error into a deliberate fallback. In the default `auto` mode,
+a keychain failure routes to the encrypted-file store **when a passphrase is
+configured**, and otherwise fails with a message pointing at `ACTUAL_TOKEN` or
+`ACTUAL_TOKEN_PASSPHRASE`. The practical guidance that follows:
+
+- **Interactive desktop** (macOS, Windows, Linux with a keyring daemon): the OS
+  keychain is used with no extra configuration.
+- **CI**: prefer `ACTUAL_TOKEN` from the platform's secret store. No on-disk
+  storage is involved at all.
+- **Headless Linux that must persist a token**: set `ACTUAL_TOKEN_PASSPHRASE`
+  to enable the encrypted-file fallback.
+
+### Prototype limitations
+
+- The endpoint contract is provisional; see below.
+- The encrypted-file fallback derives its key from a passphrase. Treat that
+  passphrase as a secret of the same weight as the token, and supply a
+  high-entropy value (the Argon2id work factor slows brute force but cannot
+  rescue a guessable passphrase).
+
+## Endpoint
+
+`create-token` calls `POST <base>/api/auth/tokens` with the login session token
+as the bearer, and reads back the minted `actl_pat_…`. The base URL is resolved
+from `--api-url`, then the `ACTUAL_API_URL` environment variable, then the
+api-service default, so a local mock or a future production path needs no code
+change. It isn't final yet. Until the server endpoint ships, treat the exact
+path and payload as provisional.

+//! Scoped personal access token (PAT) issuance against the Actual AI platform.
+//!
+//! `actual auth create-token` mints a PAT by calling the authenticated
+//! issuance endpoint with the user's existing `actual login` session token as
+//! the bearer — no second browser dance, the established session *is* the
+//! authentication for issuance. The endpoint returns the raw `actl_pat_…`
+//! exactly once; the CLI prints it once and otherwise keeps it only behind the
+//! keychain / encrypted-file store (see [`crate::auth::token_store`]).
+//!
+//! ## Endpoint contract (developed against; confirm against the backend)
+//!
+//! The backend issuance endpoint is still landing, so this module is written
+//! against the documented contract and is trivially repointed once the server
+//! ships:
+//!
+//! - `POST <base>/api/auth/tokens`
+//! - `Authorization: Bearer <session access token>`
+//! - request body: `{ "name": "<label>", "scopes": ["adr.read", …] }`
+//! - response body: `{ "token": "actl_pat_…", "id": …, "name": …, "scopes":
+//!   […], "created_at": …, "expires_at": … }` — the raw `token` is returned
+//!   exactly once.
+//!
+//! `<base>` is resolved by the command layer (the `--api-url` flag, the
+//! `ACTUAL_API_URL` env var, or the api-service default), so steering the call
+//! at a local mock or a future production path needs no code change here.

+//! Secure storage for scoped personal access tokens (PATs).
+//!
+//! A PAT minted by `actual auth create-token` is a long-lived bearer secret.
+//! It must never sit in plaintext on disk, in shell history, in process
+//! arguments, or in an agent's prompt / log stream. This module gives the CLI
+//! two storage backends and one non-interactive read path, so the raw token is
+//! shown once at mint time and thereafter only ever lives behind the OS
+//! keychain, an encrypted file, or the process environment.
+//!
+//! ## Backends
+//!
+//! - **`Keyring`** — the OS keychain (macOS Keychain, Windows Credential
+//!   Manager, Linux Secret Service) via the portable [`keyring`] crate. This is
+//!   the primary store on a desktop / interactive box.
+//! - **`EncryptedFile`** — an XChaCha20-Poly1305 AEAD file under the config
+//!   directory, with the key derived by Argon2id from a passphrase read from
+//!   `ACTUAL_TOKEN_PASSPHRASE`. This is the fallback for headless Linux / CI
+//!   that has no Secret Service daemon, where the keychain is unavailable.
+//!
+//! ## Backend selection (`ACTUAL_TOKEN_STORE`)
+//!
+//! - `auto` (default / unset): try the keychain; if it is unavailable, fall
+//!   back to the encrypted file (when a passphrase is configured). This is the
+//!   graceful-degradation path the headless-storage POC question asks about.
+//! - `keyring`: force the OS keychain.
+//! - `file`: force the encrypted file.
+//!
+//! ## Non-interactive read precedence ([`resolve`])
+//!
+//! 1. The `ACTUAL_TOKEN` environment variable — the CI path, no storage needed.
+//! 2. The OS keychain.
+//! 3. The encrypted fallback file.
+//!
+//! Token material is never written to a log or a `Debug` impl in this module.

From 6b24d73894acd26feee93a745a365755fbe85332 Mon Sep 17 00:00:00 2001
From: Ben Wisecup <ben.wisecup@gmail.com>
Date: Tue, 30 Jun 2026 21:34:19 -0400
Subject: [PATCH 2/5] fix(auth): correct issuance endpoint and build the
 keychain off D-Bus
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Point `create-token` at the real issuance route and make the crate build on
headless / CI Linux, then bring the new modules to full line coverage.

The issuance endpoint is `POST /api/oauth/tokens` (not `/api/auth/tokens`),
and `--scopes` now shows the enforced colon vocabulary (`adr:query`,
`adr:review`, `mcp:invoke`) that the rest of the login flow already uses.

The Linux keychain backend moves from the Secret Service feature to the
dbus-free kernel keyutils backend (`linux-native`). The Secret Service backend
links `libdbus` at build time, so the CLI failed to compile on any Linux host
without `libdbus-1-dev` — the real headless-storage finding, now documented in
`docs/AGENT_AUTH.md`. keyutils needs no system library and no daemon, so it
builds everywhere and works headless; macOS and Windows keep their native
keychains.

Add unit coverage for the keychain backends (through an injectable in-memory
keystore), the encrypted-file error paths, and the token-refresh and
result-printing branches.

Generated by the operator's software factory.

 ## Headless-storage finding
 
 The question this prototype set out to answer: does the keychain library degrade
-gracefully on a headless Linux box or CI runner that has no Secret Service
-daemon?
-
-The answer is no, and that is the expected, correct behavior. The `keyring`
-crate's Secret Service backend talks to a D-Bus daemon; with no daemon running,
-a store or read returns an error rather than silently dropping the secret or
-inventing a weaker store. Silent degradation is the more dangerous outcome,
-because it leaves a token written somewhere unprotected. An explicit error is
-what you want.
-
-The CLI turns that error into a deliberate fallback. In the default `auto` mode,
-a keychain failure routes to the encrypted-file store **when a passphrase is
-configured**, and otherwise fails with a message pointing at `ACTUAL_TOKEN` or
-`ACTUAL_TOKEN_PASSPHRASE`. The practical guidance that follows:
-
-- **Interactive desktop** (macOS, Windows, Linux with a keyring daemon): the OS
-  keychain is used with no extra configuration.
-- **CI**: prefer `ACTUAL_TOKEN` from the platform's secret store. No on-disk
-  storage is involved at all.
-- **Headless Linux that must persist a token**: set `ACTUAL_TOKEN_PASSPHRASE`
-  to enable the encrypted-file fallback.
+gracefully on a headless Linux box or CI runner with no desktop keyring?
+
+The first cut used the `keyring` crate's **Secret Service** backend
+(`sync-secret-service`), and the finding was sharper than expected. Secret
+Service does not fail gracefully at runtime here; it fails at **build time**.
+That backend links the system `libdbus` through `pkg-config`, so a host without
+`libdbus-1-dev` cannot compile the CLI at all. On stock Linux CI runners every
+job went red on `The system library dbus-1 required by crate libdbus-sys was not
+found`, across build, lint, test, and coverage alike. A missing runtime daemon
+is recoverable. A binary that never builds is not.
+
+The fix is to pick a Linux backend with no build-time system dependency. This
+CLI now uses `linux-native`, the kernel **keyutils** keyring, reached through raw
+syscalls: no `libdbus`, no `pkg-config`, no D-Bus daemon. It compiles on any
+Linux, including a bare CI container, and it stores secrets headless without a
+desktop session. macOS and Windows keep their native keychains (`apple-native`,
+`windows-native`), which never had the problem.
+
+Runtime degradation is still handled explicitly. In the default `auto` mode a
+keychain error routes to the encrypted-file store **when a passphrase is
+configured**, and otherwise fails loudly with a message pointing at
+`ACTUAL_TOKEN` or `ACTUAL_TOKEN_PASSPHRASE`. The CLI never invents a weaker store
+behind your back. Silent degradation would leave a token written somewhere
+unprotected, and that is the outcome worth avoiding.
+
+One property of keyutils is worth knowing. Kernel keyrings are scoped to a
+session or the persistent per-user keyring, so a secret there is less durable
+across reboots than a Secret Service entry on a desktop. For durable
+non-interactive use that does not matter, because the recommended paths avoid the
+OS keychain entirely:
+
+- **CI**: pass `ACTUAL_TOKEN` from the platform's secret store. Nothing is
+  written to disk.
+- **Headless Linux that must persist a token**: set `ACTUAL_TOKEN_PASSPHRASE` to
+  enable the encrypted-file fallback, which survives reboots at `0600`.
+- **Interactive desktop** (macOS, Windows, Linux with keyutils): the OS keychain
+  is used with no extra configuration.

Subject: [PATCH 3/5] fix(auth): satisfy the CodeQL salt scan and cover the
 auth dispatch arm

Two CI follow-ups on the create-token work.

- The AEAD salt and nonce are now returned from `random_bytes::<N>()` rather
  than filling a caller-owned `[0u8; N]` in place. Behaviour is identical (still
  an `OsRng`-filled salt and nonce), but the random value no longer flows out of
  a zero-initialized binding, which clears a false-positive
  `rust/hard-coded-cryptographic-value` CodeQL alert on the salt.
- Add a test that routes `actual auth create-token` through the `auth` command
  dispatch, returning `NotLoggedIn`, so `src/cli/commands/auth.rs` is back at
  full line coverage.

Subject: [PATCH 4/5] fix(auth): never orphan an unrevocable PAT on token-store
 failure
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`create-token` minted the PAT server-side and only then ran the local
store; a store error bailed via `?` before the token or its id were ever
printed, so the raw token was lost. The most likely store failure is a
headless Linux box with no `ACTUAL_TOKEN_PASSPHRASE` and no OS keychain —
exactly the target environment — so every failed attempt burned a live,
unrevocable token the user could neither capture nor revoke.

Close the gap from both ends:

- Add `token_store::precheck`, a non-writing probe that confirms a backend
  is available, and call it BEFORE minting. The predictable headless /
  no-passphrase case now fails cleanly with no token minted at all.
- On any residual post-mint store failure (a full disk, a keychain lock
  race the precheck cannot foresee), still surface the token and its id so
  the user can capture and revoke it, then propagate the error. A minted
  token is never silently dropped.

Route `create-token` output through injected writers so the
stdout=secret / stderr=chrome split — a load-bearing capture contract — is
unit-testable. New tests cover: the pre-mint precheck refusal, the
store-fails-after-mint recovery, and that stdout carries only the token.

Subject: [PATCH 5/5] test(auth): cover create-token precheck + output error
 paths to 100%
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The store-failure revision added `token_store::precheck` (keyring/auto arms) and
`keyring_available`, and routed `create-token` output through injected writers
with `?` error propagation. Those new lines were not fully exercised, so the
100%-per-file coverage gate failed on `token_store.rs` (97.16%) and
`create_token.rs` (95.93%).

Add test-only coverage; no production code changes:

- `precheck` under keyring and auto modes, both available and unavailable, via
  the existing in-memory keyring mock — extended with a fail-on-build toggle so
  `keyring_available`'s entry-init-failure leg is reachable without OS trickery.
- `print_unstored_token`'s no-id branch (a mint whose response carries no id).
- a failing-writer sweep that drives every `writeln!` `?` error path in
  `print_result` and `print_unstored_token`, asserting a broken output stream
  surfaces as an error rather than a false success.

Both files are now at 100% line coverage.
