A Pancakes node begins as a network-accessible, locally governed home
for Pitchfork. This page follows the work from the accounting engine
to a recoverable hosted node and its first visible Mood Ring response.
Pitchfork Core and the deployment reconciliation are ready to proceed in
parallel. No milestone is complete yet, and no Droplet creation is
authorized by readiness alone.
Parallel foundations
Software and operations meet at deployment.
The host does not need to wait for all application work, and the
application does not need a server to prove its core behavior. Both
foundations must be ready before the node is installed on the Droplet.
Track A
Node software
A1Ready
Pitchfork 0003 · Core foundation
Build the installable, deterministic, database-independent accounting engine and its persistence contracts.
A2Blocked
Pancakes 0007 · Node foundation
Build Flask, SQLAlchemy adapters, Alembic migrations, health checks, configuration, and the atomic unit of work.
Waiting on Pitchfork 0003.
A3Queued
Local vertical slice
Submit one authorized event, settle it once, persist resource state, retrieve its projection, and prove rollback and idempotency with SQLite.
Track B
Hosting foundation
B1Ready
Site Ops 0018 · Consolidation
Reconcile hostnames, capacity, runtime layout, security, health, backup, and rollback decisions into one deployment baseline.
B2Blocked
Site Ops 0019 · Checkpoint 1
Provision and harden the distinct Ubuntu Droplet, establish administrator and service boundaries, and verify reboot recovery.
Waiting on the applicable 0018 decisions and explicit spending authorization.
Both foundations ready↓
Converged sequence
From private node to visible response.
1
Deploy the private developer node
Checkpoint 2
Run systemd → Gunicorn → Pancakes Flask → Pitchfork on the hardened host, initially with SQLite and loopback-only access.
2
Introduce hosted persistence
Checkpoint 3
Add PostgreSQL and Alembic-managed schema, then prove durability, concurrent idempotency, backup, and restoration.
3
Open bounded HTTPS access
Checkpoint 4
Add the selected hostname, Nginx, TLS, and only the externally approved routes after authentication, privacy, logging, and rate-limit review.
4
Complete the Mood Ring smoke test
Checkpoint 5
Send only a derived symbolic colour, settle it through Pitchfork, retrieve the background projection, and verify the visible response after restart, reboot, and restoration.
Definition of the first proof
An authorized network request is settled exactly once, its resulting
state is persisted atomically, and a projection can be retrieved after
restart without exposing the private record that produced it.
