chore (changelog): note transcript tool-call sanitization hardening

CHANGELOG.md

@@ -70,6 +70,7 @@ Docs: https://docs.openclaw.ai
 - Agents: classify external timeout aborts during compaction the same as internal timeouts, preventing unnecessary auth-profile rotation and preserving compaction-timeout snapshot fallback behavior. (#9855) Thanks @mverrilli.
 - Agents: treat empty-stream provider failures (`request ended without sending any chunks`) as timeout-class failover signals, enabling auth-profile rotation/fallback and showing a friendly timeout message instead of raw provider errors. (#10210) Thanks @zenchantlive.
 - Agents: treat `read` tool `file_path` arguments as valid in tool-start diagnostics to avoid false “read tool called without path” warnings when alias parameters are used. (#16717) Thanks @Stache73.
+- Agents/Transcript: drop malformed tool-call blocks with blank required fields (`id`/`name` or missing `input`/`arguments`) during session transcript repair to prevent persistent tool-call corruption on future turns. (#15485) Thanks @mike-zachariades.
 - Tools/Write/Edit: normalize structured text-block arguments for `content`/`oldText`/`newText` before filesystem edits, preventing JSON-like file corruption and false “exact text not found” misses from block-form params. (#16778) Thanks @danielpipernz.
 - Ollama/Agents: avoid forcing `<final>` tag enforcement for Ollama models, which could suppress all output as `(no output)`. (#16191) Thanks @Glucksberg.
 - Plugins: suppress false duplicate plugin id warnings when the same extension is discovered via multiple paths (config/workspace/global vs bundled), while still warning on genuine duplicates. (#16222) Thanks @shadril238.
