1.92.0 / build 185

Requested by Brad: a measurement of four weeks of his Claude Code use found that long conversations, not the models' own writing, used most of his plan (65% of the cost came from requests made after a conversation passed 200K tokens), and that subagents ran on the same model as the conversation that started them. He asked for a context limit and a subagent policy in Pocket itself, for every agent, with a choice of how and when to compact. This release is phase 1 of the spec.

• Policy. context-policy.mjs checks and reads contextPolicy (compaction.mode agent | limit, compaction.limit 50K–1M; workers.model default | tier-down; workers.effort) and turns it into each engine's launch options. The default changes nothing, and saving the default stores null.
• Claude Code. spawnRunner adds env to --settings: CLAUDE_CODE_AUTO_COMPACT_WINDOW, CLAUDE_CODE_SUBAGENT_MODEL (opus under Fable or Mythos, sonnet under Opus) and CLAUDE_CODE_SUBAGENT_EFFORT. --settings outranks ~/.claude/settings.json env; this was verified on 2.1.316 (a 150K window in /context, and a subagent on Sonnet 5.5 at low effort while settings.json said opus). The leader is the turn's model, then Pocket's default, then the CLI's. Runner markers record policyKey, and a reused process whose policy changed is replaced (context policy changed) unless it is running background jobs.
• Codex. thread/start, thread/resume and thread/fork carry config: model_auto_compact_token_limit (85% of the limit), agents.default_subagent_model (the newest GPT Sol under GPT Astra, codexNewestSol) and agents.default_subagent_reasoning_effort. The leader is the turn's model, else config.toml's model (codexDefaultModel). A session opened with another policy is reopened. This was verified on 0.166.0: a sub-agent with no model ran gpt-6.1-sol at low.
• Engines. The contextPolicy feature is true for Claude and Codex and false for OpenRouter: OpenCode's compaction has no token limit, so that comes in phase 2.
• Settings. Agents & instance → Context and subagents: Compact conversations, Subagent model, Subagent effort, and a note saying which agents it applies to. Saving restarts idle processes.
• Tests: context-policy.test.mjs (defaults, tiers, launch options, validation; over HTTP, the settings round trip, the Claude --settings env before and after a change, a Fable leader, a Codex default leader from config.toml, and clearing). fake-claude records settingsEnv, and fake-codex records each thread's config and model.
