- Workspace/oc-path: add the `oc://` addressing substrate (`src/oc-path/`) — a universal, kind-dispatched path scheme for addressing leaves and nodes inside markdown, jsonc, jsonl, and yaml workspace files, with `parseOcPath`/`formatOcPath`, per-kind `parseXxx`/`emitXxx`, universal `resolveOcPath`/`setOcPath`/`findOcPaths` verbs, the `__OPENCLAW_REDACTED__` sentinel emit guard, and the new `openclaw path resolve|find|set|validate|emit` CLI for shell-level inspection and surgical edits. Implements #78051. (#78678) Thanks @giodl73-repo.

- Runtime/performance: avoid full-array sorting while auto-selecting providers, resolving supported thinking levels, picking node last-seen timestamps, and extracting Codex usage-limit messages. Thanks @shakkernerd.

- Plugins/doctor: avoid full-array sorting while selecting ClawHub search/archive results and bounded dreaming doctor entries. Thanks @shakkernerd.

- Agents/compaction: keep contributor diagnostics to a bounded top-three selection without sorting the full history. Thanks @shakkernerd.

- Telegram: preserve the channel-specific 10-option poll cap in the unified outbound adapter so over-limit polls are rejected before send. (#78762) Thanks @obviyus.

- Slack: route handled top-level channel turns in implicit-conversation channels to thread-scoped sessions when Slack reply threading is enabled, keeping the root turn and later thread replies on one OpenClaw session. (#78522) Thanks @zeroth-blip.

- Telegram: re-probe the primary fetch transport after repeated sticky fallback success so transient IPv4 or pinned-IP fallback promotion can recover without a gateway restart. Fixes #77088. (#77157) Thanks @MkDev11.
