Diego Rodrigues de Sa e Souza 5ac4637816 docs: reorganize docs/ + accuracy audit + drop Node 20 (rebased onto current release tip) (#5262)
* docs: move superpowers/research artifacts to isolated _tasks repo + docs tree cleanup

- Move docs/superpowers/{plans,specs} and docs/research/* into the gitignored,
  separately-versioned _tasks/ repo; untrack the two tracked research design docs.
- Add CLAUDE.md "Planning & Research Artifacts" section overriding the superpowers
  default save paths (docs/... -> _tasks/...); align REPOSITORY_MAP and
  DOCUMENTATION_OVERHAUL_PLAN with the new convention.
- Drop 4 now-obsolete /api/discovery/* entries from check-docs-symbols allowlist
  (stale-enforcement) and refresh code/spec path comments to _tasks/...
- Sweeps in concurrent docs-tree restructuring (root-level provider/guide docs,
  compression spec cleanup, .mcp.json.example removal).

* docs: reorganize docs/ tree + fix stale facts across ~26 docs

Phase A — reorganization:
- Move 7 orphan root docs into subfolders (providers/ created; TIERS+USAGE_QUOTA→guides/;
  plugins+PLUGIN_SDK→frameworks/); delete 8 obsolete/redundant docs (SUBMIT_PR superseded
  by CONTRIBUTING; DOCUMENTATION_OVERHAUL_PLAN; INCIDENT_RESPONSE/PERF_BUDGETS/THREAT_MODEL;
  3 ops snapshots). Rebuild README index (was missing ~40 files) + per-folder meta.json nav.
- Clean 14 dangling doc-path references in bin/ ops scripts, scripts/, workflow, tests;
  fix the dockerignore-docs-coverage required-docs path (PROVIDERS→providers/CLAUDE_WEB).

Phase B — content accuracy (verified against code, not the audit summary):
- Functional: ENVIRONMENT flag defaults (INPUT_SANITIZER/MCP_ENFORCE_SCOPES=true,
  COMPRESS_DESCRIPTIONS=false, dynamic heap); MCP-SERVER notion tool names (omniroute_*→
  notion_*) + counts 87→94; coverage gate 75/70→60/60/60/60 (RELEASE_CHECKLIST, COVERAGE_PLAN,
  ERROR_SANITIZATION, CONTRIBUTING); pre-push hook description; regenerate PROVIDER_REFERENCE (237).
- Count drift: providers 237, executors 70, migrations 106, db modules 94, oauth 19,
  strategies 17, MCP 94, flags 38, TS 6.0, open-sse ~900/services 294 across architecture/
  frameworks/ops docs; AUTO-COMBO 9→12 factors w/ correct DEFAULT_WEIGHTS; REASONING +2
  patterns; STEALTH UA defaults; AGENT_PROTOCOLS +cursor-cloud/list-capabilities;
  LANGUAGE_PACKS +id pack.
- Kept Node 20 (runtime guard accepts 20.20.2+; only engines is stricter) and MCP scopes=13
  (mcpScopes.ts) — both were correct in the docs; corrected only the attribution.

* docs: finish content refresh — compression engines, CLI_TOKEN merge, metadata sweep

- Compression: document the additional built-in engines (CCR, headroom, ionizer,
  session-dedup) in COMPRESSION_ENGINES; clarify LLMLingua-2 is the ultra-mode SLM
  backend + cross-ref the extra engines in EXTENDING_COMPRESSION; add the id
  (Indonesian) language pack to LANGUAGE_PACKS.
- AUTO-COMBO: replace the orphan 'How tiers fit' weight table (stale weights) with a
  pointer to the canonical 12-factor DEFAULT_WEIGHTS table.
- Security: merge CLI_TOKEN_AUTH.md (legacy 32-char SHA-256 format) into CLI_TOKEN.md
  as a 'Legacy format — still accepted' section (server accepts both HMAC + legacy),
  delete CLI_TOKEN_AUTH.md, drop it from the index + security nav.
- Metadata: bump stale frontmatter (version/lastUpdated) to 3.8.40/2026-06-28 across the
  doc set audited this pass, and normalize the in-body 'Last updated' header lines to match.

* fix(runtime): drop Node 20 from supported range + align all docs/diagrams/counts

- Node minimum is now 22 (aligned with package.json engines). SUPPORTED_NODE_RANGE in
  src/shared/utils/nodeRuntimeSupport.ts (and the bin/ mirror) drops the 20.x line →
  '>=22.22.2 <23 || >=24.0.0 <27'; getNodeRuntimeSupport now rejects Node 20 as
  unsupported-major. Test updated (TDD): node-runtime-support.test.ts asserts Node 20
  rejected. Docs aligned (TROUBLESHOOTING ×2, TERMUX, RELEASE_CHECKLIST, CODEBASE,
  CLI-TOOLS, README, llm.txt + 42 i18n llm.txt mirrors, skills/cli-serve).
- Diagrams regenerated: mcp-tools-87 -> mcp-tools-94 (34 base + pool 6 = 94) and
  auto-combo-9factor -> auto-combo-12factor (correct DEFAULT_WEIGHTS); SVGs re-rendered
  via mermaid-cli; doc refs + diagrams/README updated; fixed a pre-existing broken
  resilience-3layers image path.
- CLAUDE.md + AGENTS.md aligned to real counts (237 providers, 94 MCP tools / 34 base,
  106 migrations, 94 db modules, 12-factor auto-combo, 17 strategies); README provider
  count 231 -> 237; executor count corrected to 68 (provider executors, excl base/index)
  and OAuth to 18 across architecture docs. check:docs-all now passes (0 strict drift,
  0 broken links); removed dead .mcp.json.example doc link.

* fix(services): update installer Node hint to >=22.22.2 (aligned with dropped Node 20)

* docs: realign counts to current release tip after rebase

The release tip advanced while this work was in flight (Gemini CLI provider/executor
removed by #5246, plus other PRs). Re-counted against the current code and updated:
providers 237->236, executors 68->67, OAuth modules 18->17, open-sse services 294->298;
regenerated PROVIDER_REFERENCE.md (236). check:docs-all passes (0 strict drift).

* docs(changelog) + i18n: record Node 20 drop + fix nodeIncompatibleHint

- CHANGELOG: add [3.8.40] entries for the Node 20.x removal (runtime) and the docs
  reorganization/accuracy audit.
- i18n: nodeIncompatibleHint across all 42 locales no longer lists Node 20.x as
  supported (ASCII + CJK full-width variants), aligned with the dropped Node 20.

* fix(docs): repair CI breakages from the doc moves

- test: cli-plugin-system asserted docs/dev/plugins.md exists; the file moved to
  docs/frameworks/PLUGINS.md — point the test at the new path (Unit fast-path 2/2 fix).
- frontmatter: PLUGINS.md and PLUGIN_SDK.md moved into the fumadocs-indexed
  docs/frameworks/ which requires a 'title' frontmatter; the missing frontmatter
  failed the Next.js MDX build (dast-smoke 'invalid frontmatter'). Added frontmatter
  to both, plus the providers/ docs (consistency; that folder is not indexed).

Diagrams

Mermaid sources (.mmd) and exported SVGs for OmniRoute v3.8.0 architecture flows.

How to update

  1. Edit *.mmd.
  2. Re-render: npm run docs:render-diagrams (uses @mermaid-js/mermaid-cli).
  3. Commit both .mmd and .svg.

If @mermaid-js/mermaid-cli is not available locally, install it once:

npm install -g @mermaid-js/mermaid-cli

The script renders every .mmd in docs/diagrams/ into docs/diagrams/exported/*.svg with a white background, suitable for both dark and light themes.

Linking from a doc

From a doc in docs/<subfolder>/, the relative path becomes ../diagrams/...:

![Request pipeline](../diagrams/exported/request-pipeline.svg)

> Source: [../diagrams/request-pipeline.mmd](../diagrams/request-pipeline.mmd)

From the repo root (e.g. CLAUDE.md):

![Resilience layers](./exported/resilience-3layers.svg)

Conventions

  • One concept per diagram. Don't try to fit the whole platform in one chart.
  • Keep node labels short (3-6 words). Use <br/> for line breaks inside nodes.
  • Prefer flowchart LR for pipelines and flowchart TB for layered models.
  • Use sequenceDiagram for interactive (request/response) flows.
  • Use erDiagram for database schema overviews.
  • Update both .mmd and .svg in the same commit. Keep them in lock-step.
