Fundamentals production deployment

This is the one-time production setup for the Dolt earnings and SEC fundamentals imports. Both imports remain shadow inputs until the separate A5 scoring-cutover approval. Do not add OS cron entries: the application scheduler owns both jobs.

What the deployment adds

Dolt Earnings Import (shadow) runs daily at 02:30 America/New_York.
SEC Fundamentals Import (shadow) runs daily at 04:00 America/New_York.
Both jobs are visible, toggleable, and manually triggerable in Admin → Jobs.
Cron expressions are editable in Admin → Schedule.
Every attempt is recorded in data_import_runs; failures also create a system event. A failed validation does not promote partial data.

The systemd service uses one application worker. The import framework also holds a PostgreSQL advisory lock per source, so an overlapping manual/scheduled run is skipped safely.

Prerequisites

The production .env at /opt/signalplatform/.env must contain:

DOLT_BINARY=/usr/local/bin/dolt
DOLT_DATA_DIR=/var/lib/signal-platform/dolt
DOLT_EARNINGS_SUBDIR=earnings
DOLT_MIN_FREE_DISK_GB=5.0
SEC_USER_AGENT=signal-platform/1.0 (contact: real-address@example.com)
SEC_REQUEST_SPACING_SECONDS=0.2

Use a real monitored contact address. Keep at least 5 GB free at the Dolt data path; 8–10 GB gives comfortable growth headroom. The data directory must stay outside /opt/signalplatform, because deployments use rsync --delete there.

One-time provisioning

First deploy the commit containing this bundle to production. Then SSH to the server and run:

cd /opt/signalplatform
sudo bash ./deploy/provision_fundamentals.sh
sudo -u deploy bash ./deploy/provision_fundamentals.sh --check
sudo systemctl restart signalplatform.service
curl -fsS http://127.0.0.1:8998/api/v1/health

The provisioner is idempotent. It installs the pinned Dolt version, creates the persistent directory as deploy:deploy, clones post-no-preference/earnings, configures a repository-local author identity for dolt pull, verifies free space and .env, and refuses an unexpected Dolt version. It does not modify PostgreSQL or start an import. The public clone does not require dolt login.

For a server provisioned before the author-identity check was added, repair the existing clone once with:

sudo -u deploy -H /usr/local/bin/dolt config --global --add user.name "Signal Platform"
sudo -u deploy -H /usr/local/bin/dolt config --global --add user.email "signal-platform@localhost"

Do not replace the pinned version with latest. A future Dolt upgrade should be a reviewed change to DOLT_VERSION, followed by the same provision/check flow.

First-run verification

In Admin → Jobs, wait until no other job is running, then:

Trigger Dolt Earnings Import (shadow). Expect completed with import status promoted; a repeat without an upstream change should report no_op.
Trigger SEC Fundamentals Import (shadow). The first run performs the tracked-universe history backfill and can take materially longer than a daily incremental run. Expect completed with import status promoted.
Check Admin → System Events. There should be no new import error.
Confirm the next-run times correspond to 02:30 and 04:00 New York time.
Open several ticker pages and confirm the fundamentals panel has populated data and still handles partial/missing issuers cleanly.

Optional database verification:

SELECT source, status, revision, source_max_date, started_at, completed_at,
       validation_json
FROM data_import_runs
WHERE source IN ('dolt_earnings', 'sec_facts')
ORDER BY id DESC
LIMIT 10;

SELECT count(*) FROM earnings_events WHERE source = 'dolt_earnings';
SELECT count(*), count(DISTINCT cik) FROM fundamental_snapshots;

During the longer first SEC run, execute the following in a second SSH session. It opens an independent database connection and attempts the same source lock:

cd /opt/signalplatform
sudo -u deploy .venv/bin/python - <<'PY'
import asyncio

from sqlalchemy import text

from app.database import engine
from app.services.data_import import _advisory_key


async def main():
    key = _advisory_key("sec_facts")
    async with engine.connect() as connection:
        acquired = await connection.scalar(
            text("SELECT pg_try_advisory_lock(:key)"), {"key": key}
        )
        print("UNEXPECTED: lock acquired" if acquired else "OK: source lock is busy")
        if acquired:
            await connection.execute(
                text("SELECT pg_advisory_unlock(:key)"), {"key": key}
            )


asyncio.run(main())
PY

Expect OK: source lock is busy. This is the remaining live-PostgreSQL mutual-exclusion check; SQLite unit tests cannot exercise PostgreSQL advisory locks. A second Admin trigger should independently report the job as busy.

Failure and rollback

Disable the failing shadow job in Admin → Jobs. This stops scheduled imports without changing existing data or the legacy scoring path.
Inspect the job runtime, latest data_import_runs.validation_json, service logs, and Admin → System Events before retrying.
Re-run sudo -u deploy bash ./deploy/provision_fundamentals.sh --check for binary, clone, permission, disk, or environment failures.
The Dolt clone is a reproducible cache and does not need a bespoke backup. PostgreSQL (including earnings_events, fundamental_snapshots, and import audit rows) must remain covered by the normal production database backup.
Do not proceed to A5 while either shadow feed is unhealthy or the parity gate has not received explicit approval.
