Docs for Lite 2026.10.6, core 0.63.0 and ThinkWatch 3.2.0

[fylorn]

Site docs for the joint release: ThinkWatch Lite 2026.10.6 (core 0.63.0, ThinkWatch-Core#292, ThinkWatch-Lite#285, #286) and ThinkWatch 3.2.0 (ThinkWatch#81–#83).

Lite

• features.md (en, zh-CN):
  • Round-robin groups: a weight per member and Distribute by (ratio, speed, reliability, or both).
  • Move to the next upstream when the start times out, and the slot wait in Settings › Failover.
  • A concurrency limit per upstream, and model specs set by hand (Specs…).
  • Key usage limits, with the Limit reached mark and the notifications at 80% and at the limit.
  • New marks in a request's attempts: a start that timed out with possibly billed input, skips at the concurrency limit, and time queued. Requests refused by a usage limit or because every upstream was full are labelled.
  • Responses WebSocket turns are listed as requests.
  • Check-up findings now appear on the upstream's row; the paragraph about the removed tab is gone.
• failover-and-load-balancing.md:
  • The strategy table now says weights decide the round-robin split, and that Lowest latency is measured as time to first token per attempt.
  • New notes on weights and the distribution factors, slow starts and concurrency limits.
  • The guide now follows 2026.10.6.
• keep-api-keys-from-relays.md: points at the marks on the upstream's row instead of the removed Check-up tab.
• Lite page: the keys tile mentions usage limits.

ThinkWatch

• deployment-guide.md adds section 4.6, External PostgreSQL and Redis, following the chart README:
  • Postgres must be reached directly or through a session-mode pooler, not a transaction-mode one, because schema setup holds a session advisory lock.
  • Redis Cluster uses redis-cluster://.
  • Redis over TLS uses rediss:// / rediss-cluster://, with REDIS_CA_CERT / redis.caSecret for a private CA.
• The Helm install example no longer sets secrets.databaseUrl / secrets.redisUrl, which the chart does not have.
• configuration.md: DATABASE_URL and REDIS_URL link to the new section.
• Section 4.4, External Secrets: the ExternalSecret example now merges JWT_SECRET and ENCRYPTION_KEY into the chart's own <release>-secrets (creationPolicy: Merge, external-secrets.io/v1). Before, it used lower-case keys the server never reads and a Secret the chart overwrites. The text says to leave secrets.jwtSecret / secrets.encryptionKey unset, to restart the server after the first sync, and that the database URLs come from externalUrl.

• The core docs snapshot (src/data/core-docs). It is refreshed with CORE_DOCS_REF=v0.63.0 pnpm core-docs once v0.63.0 is tagged.

pnpm build passes.
