- Around line 38-40: Update the isAuthenticated handler to resolve credentials
from env.REASONIX_HOME instead of env.REASONIX_STATE_HOME, defaulting on Windows
to APPDATA/reasonix and otherwise to AppData/Roaming/reasonix when APPDATA is
unset, then check for .env under that resolved directory.
- Around line 35-36: Update pickAuthMethod so it always returns null for the
reasonix-setup authentication method, preventing core.ts from invoking
authenticate until terminal-flow support exists.
- Line 40: Update isAuthenticated to resolve the credentials file from
REASONIX_HOME rather than REASONIX_STATE_HOME, and parse it with
Reasonix-compatible rules so empty, comment-only, tombstone, and
empty-assignment files return false while a non-empty provider assignment
returns true. Add coverage for both environment variables and invalid
credential-file contents.

reasonix.ts to accept valid non-empty assignments with one-character values and
an optional export prefix, while continuing to reject empty assignments; add
regression coverage for plain and export-prefixed forms plus empty values.

The generic ACP adapter makes this small, but the branch currently conflicts and the provider-specific credential/auth behavior has no tests. Please rebase and add focused coverage for REASONIX_HOME/Windows fallback plus valid, empty, comment-only, quoted-empty, and export-prefixed .env values before adding Reasonix to the default fleet.

- Around line 30-35: Update hasReasonixCredentials so whitespace around the
assignment value is limited to spaces and tabs, preventing matching across
newlines; preserve valid non-empty values while rejecting empty assignments
followed by comments or blank lines, and add regressions covering both cases.

✅ Action performedReview finished.

Tests added — 16 covering REASONIX_HOME, Windows fallback, and the .env grammar (valid, empty, comment-only, quoted-empty, export-prefixed). Branch is clean against main now, no conflict. |
|
Reviewed against current main. The driver shape is right and the ACP core does inherit most of the contract — but the credential lookup diverges from its siblings in a way that's actually test-pinned.
Mirroring that one line would make this consistent with the rest of the fleet, and it also needs a rebase (currently conflicting). Worth finishing — a new ACP harness is cheap to add now that the core exists. |
Reasonix is a cache-first DeepSeek coding agent with a documented ACP v1 implementation (`reasonix acp`, NDJSON JSON-RPC 2.0 over stdio). This adds it as a support object on the generic ACP runtime in server/drivers/acp/core.ts — one file plus a registration line and a default-fleet entry. Auth is lenient (authFailure continue): the only advertised method is the terminal `reasonix-setup` flow, which a GUI host cannot drive, so turns proceed on Reasonix ambient login (~/.reasonix/.env). Verified live against reasonix 1.24.1: initialize advertises protocolVersion 1 and the reasonix-setup terminal auth method.
CodeRabbit review: - pickAuthMethod returned "reasonix-setup", which made core.ts issue a terminal authenticate RPC the GUI host cannot drive. Return null; rely on the ambient <Reasonix home>/.env login (authFailure continue). - isAuthenticated resolved REASONIX_STATE_HOME, but that relocates runtime state, not credentials. Resolve REASONIX_HOME (default ~/.reasonix, %APPDATA%\reasonix on Windows) per upstream CONFIG_PATHS.md. - .env existence alone was a false positive; now require a non-empty KEY=value line.
Reasonix accepts `export KEY=value` and quoted values when reading .env (CONFIG_PATHS.md). The old `.+\\S` also rejected one-char values like `KEY=x`. New matcher: optional export prefix, at least one non-space char after `=`, still rejects empty assignments.
Empty assignment followed by a comment (KEY=\n# comment) matched because \s* after '=' consumed the newline. Restrict to [ \t]*.
