Players Engine is a one-person company, which means there is no architecture review board, no security team down the hall, and nobody to blame when a shortcut comes due. The replacement for all of that is a short list of standards, written down and applied without exceptions. Publishing them here keeps them honest — it's harder to quietly break a rule the internet can read. The devlog covers most of these in depth; this page is the index.
Validate at every boundary
Every request that crosses into a service is validated against a schema before a line of business logic runs — types, shapes, ranges, all of it. The same schema definition produces the static types, the runtime validator and the API documentation, so the three can never drift apart. Data you didn't validate is data you don't have; you have a guess. The approach is described in one schema, three jobs.
Fail fast, fail loud
Configuration is validated once, at startup. If a required environment variable is missing or malformed, the service refuses to boot — it does not limp along until the missing value is needed at 2 a.m. Secrets live in a managed secret store, never in code, and never with hardcoded fallbacks. The full discipline is in environment variables and secrets without foot-guns.
Structured logs or it didn't happen
Every log line is structured JSON with request context attached. Unstructured printout debugging is banned in production paths — partly for grep-ability during incidents, partly because at cloud prices, logging is a product with a bill. Levels are chosen so that the expensive tiers stay quiet unless something is genuinely wrong. More in structured logging on a budget.
Cost-aware by default
Every technical decision is weighed against what it costs to run, because a bootstrapped platform that outspends its runway helps nobody. Services scale to zero when idle. Reads are indexed and O(1) wherever possible instead of fan-out queries. Paid third-party calls sit behind validation, idempotency and rate limits. Where cost and latency conflict at this stage, cost usually wins — and the trade-off gets written down. The reasoning is laid out in scale-to-zero is a budget strategy.
Least privilege, no long-lived keys
Deployments authenticate to the cloud with short-lived, workload- scoped credentials — there are no service-account key files sitting in CI secrets waiting to leak. Internal services hold the minimum permissions they need and nothing more. Auth is verified once at the edge and never re-invented per service. See keyless deploys with Workload Identity and JWT at the edge.
Documentation moves with the code
A feature isn't done when it works; it's done when the docs that describe the system reflect it. Architecture notes, operational runbooks and the feature overview are updated in the same change that alters behaviour — never as a follow-up that somehow never arrives. Six months from now, the only teammate available to explain a decision is the document that recorded it.
Accessibility is a floor, not a feature
Interactive targets meet minimum hit-size requirements, body text stays readable, layouts hold together from small phones to wide desktops, and keyboard users are first-class. This gets verified systematically, not vibes-checked — the method is documented in testing responsive layouts, 360 to 1920.
Ship small, verify, repeat
Changes land as small, reviewable units that go through the full pipeline — branch, tests, review, merge — even when the author and the reviewer are the same person, because the discipline is the point. Nothing merges on "it should work"; it merges on evidence. And when something breaks anyway, the fix starts with a written root cause, not a hot patch.
These standards will evolve — the platform is young and so is this list. What won't change is that the current version stays public, right here.
