Weekly development log 2026‑W37: Compare models, then route work by capability

01

Full-history review and additions

Comparison and capability routing expanded alongside credential exclusions and skill budgets. Weekend symlink/export-ownership security fixes are separate evidence from product comparison features.

All reachable history of main 0641c480 was rechecked on 2026-10-18. Counts use committer dates from Monday 00:00 through Sunday 23:59:59 KST, including merges, releases and distinct parallel-branch commits. Commit counts are not feature counts. Tests and operational measurements below are historical source records, not evaluations rerun for this refresh.

What changed

• Compare mode runs two models against the same question in a split view, then gained a per-lane Thinking toggle. It is a product comparison surface, not a benchmark claim (#807, #810).
• Agent Tasks now show parallel-agent groups as live state. The same line corrected unresolved $ref tool arguments, empty-array loops, final-turn time budgets, partial output retention, and sub-agent timeout retries (#804, #813, #815–#817).
• Skills preserve stored indentation and triggers, warn when the injection budget is exceeded, and exclude persona skills from the load_skill catalog. When eligible skills exceed the aggregate cap, the model selects which to load; that is bounded by the configured cap rather than an unrestricted prompt expansion (#822–#825).
• Model and input boundaries were tightened alongside that work. The NVIDIA NIM catalog was refreshed to 22 free endpoints, whitespace is preserved in long code and secret fields, and reasoning-only turns are no longer promoted to answers while Korean jamo input is recognized as Korean (#820, #824, #826).
• macOS now distributes the native Companion path only; Electron update defaults, publishing, and bridge behavior were removed. Companion approval waits surface as native notifications, and authentication no longer drops a message that arrives before completion (#828, #830, #831).
• Capability routing replaced the separate modality-model axis. A Planner can choose parallel image, vision, audio, video, web, and text work before synthesis; follow-ups made video jobs resumable, retained completed work, and tightened storage, ownership, cost, and execution boundaries. The 1.61.0 settings UI exposes six capability groups, while installation gained named instances, public URL setup, and database backup/restore (#832–#852).
• The final stretch restored bottom auto-scroll after mobile responses and updated OpenAI SDK 7, MCP protocol negotiation, and structured-output fallback. iOS gained orchestrator progress, media, sub-agent, model-comparison, and capability-assignment surfaces, while a missing server-filesystem seed was repaired for new installations (7bb2db1, #854–#856).
• Live checks then exposed web push registration, slash-command expansion persistence, developer-document placeholders, Quickstart URL substitution, duplicate 404 messages, and three blockers that prevented Deep Research from completing. Missing scroll containers on three workspace pages were fixed next, and a security re-review closed seven findings, including a local-bridge symlink write escape and a skill-export IDOR, plus three vulnerable dependencies. The week closed on 1.62.3 (#858, #860–#864).
