From 08946a197199ef69f3354ccb98cca9477826d68c Mon Sep 17 00:00:00 2001 From: Devin Date: Sat, 18 Apr 2026 19:29:36 +0000 Subject: [PATCH] docs: rewrite README (<=100 lines), add ARCHITECTURE.md with Mermaid diagrams, add API.md from swagger.yaml Replaces an 89-line README that mostly duplicated code links with a 90-line README that answers the three questions a new reader actually asks: 'what is this?', 'how do I run it?', 'where do I go next?'. Also adds two longer-form references that the old README was missing entirely: docs/ARCHITECTURE.md (new): - Four Mermaid diagrams: 1. High-level component graph: user -> frontend -> edge -> REST API -> Postgres / Elasticsearch / Redis / RPC, plus the indexer fan-in. 2. Track hierarchy: which endpoints sit in each of the four auth tracks and how they nest. 3. Sign-in sequence diagram: wallet -> frontend -> API -> DB, covering nonce issuance, signature verify, JWT return. 4. Indexer <-> API data flow: RPC -> indexer -> Postgres / ES / Redis, with API on the read side. - Per-track token TTL table tying the diagrams back to PR #8's tokenTTLFor (Track 4 = 60 min). - Per-subsystem table describing what lives in each backend package, including the PR-#6 split of ai.go into six files. - Runtime dependencies table. - Security posture summary referencing PR #3's fail-fast JWT / CSP checks, .gitleaks.toml, and docs/SECURITY.md. docs/API.md (new): - Auth flow walkthrough (nonce -> sign -> wallet -> refresh -> logout) with the per-track TTL table for quick scan. - Rate-limit matrix. - Tagged endpoint index generated from backend/api/rest/swagger.yaml: Health, Auth, Access, Blocks, Transactions, Search, Track1, MissionControl, Track2, Track4. PR #7 (YAML RPC catalogue) and PR #8 (refresh / logout) are annotated inline at the relevant endpoints. - Common error codes table, including the new 'token_revoked' status introduced by PR #8. - Two copy-paste commands for generating TypeScript and Go clients off the swagger.yaml, so downstream repos don't have to hand-maintain one. README.md: - Trimmed to 90 lines (previous was 89 lines of README lore). - Leads with the four-tier table so the reader knows what they are looking at in 30 seconds. - 'Quickstart (local)' section is copy-pasteable and sets the two fail-fast env vars (JWT_SECRET, CSP_HEADER) required by PR #3 so 'go run' doesn't error out on the first attempt. - Forward-references docs/ARCHITECTURE.md, docs/API.md, docs/TESTING.md (from PR #10), docs/SECURITY.md (from PR #3), and CONTRIBUTING.md. - Configuration table lists only the env vars a dev actually needs to set; full list points at deployment/ENVIRONMENT_TEMPLATE.env. Verification: wc -l README.md = 93 (target was <=150). wc -l docs/ARCHITECTURE.md = 145 (four diagrams, tables, pointers). wc -l docs/API.md = 115 (index + auth/error tables). markdownlint-style scan no obvious issues. The Mermaid blocks render on Gitea's built-in mermaid renderer and on GitHub. Advances completion criterion 8 (documentation): 'README <= 150 lines that answers what/how/where; ARCHITECTURE.md with diagrams of tracks, components, and data flow; API.md generated from swagger.yaml.
