ax dashboard reads only the SQLite event log and ignores Postgres configuration

[joycel-github]

What

ax dashboard always opens the SQLite event log and has no Postgres code path. When the controller is configured to use a Postgres event log (eventlog.postgres.dsn / AX_EVENTLOG_DSN), the dashboard does not read it and shows no data.

Where

cmd/ax/dashboard.go (runDashboard):

• Reads cfg.EventLog.SQLiteConfig.Filename unconditionally (dashboard.go:76)
• Opens the DB with sql.Open("sqlite", dbPath) (dashboard.go:83)
• Runs CREATE TABLE IF NOT EXISTS ... on that SQLite handle (dashboard.go:95+)

There is no branch that inspects cfg.EventLog.Postgres, unlike ax serve, which supports Postgres via eventlog.postgres.dsn.

Impact

For a Postgres-backed deployment, ax dashboard:

• ignores the configured Postgres DSN,
• opens/creates an empty SQLite database at the (possibly empty/default) SQLiteConfig.Filename,
• silently renders an empty conversations/executions list,

with no error indicating the store mismatch.

Repro

1. Configure ax.yaml with a Postgres event log:

   eventlog:
     postgres:
       dsn: ${AX_EVENTLOG_DSN}

2. Run the server and create a conversation (ax serve + ax exec --server ...).
3. Run ax dashboard --config ax.yaml.
4. The dashboard is empty; the Postgres data is never read.

Expected

Either:

• ax dashboard reads the same event log backend as ax serve (i.e. support Postgres), or
• it fails fast with a clear error when a non-SQLite event log is configured, instead of silently opening an empty SQLite DB.

Notes

Appears to be a known limitation. Filing to track adding Postgres support (or an explicit guard/error).
