…dedup on the wire spelling Rebasing this onto main needed two substantive changes, not just conflict resolution. **The --help probe no longer exists.** This branch gated `--system-prompt-snapshot` behind `claudeCliHelpSupportsFlag(cliHelp, ...)`, but milind-soni#1214 removed help-text probing from the Claude driver — `cliHelp`, `claudeCliHelpSupportsFlag` and the fake CLI's `--help` branch are all gone from main, which reverted a3b1d61 back to version floors. Left as written, this branch would not typecheck, and its new tests would spawn the fake CLI with `--help`, get no answer, and block until the 8s timeout. Ported to main's existing mechanism instead: `--system-prompt-snapshot` is registered in CLAUDE_FLAG_FLOORS at 2.1.267 (the first CLI that accepts it) and gated with `claudeCliSupports(cliVersion, ...)`, exactly like --strict-mcp-config, --setting-sources and --autocompact. Below the floor the recorded prompt simply is not refreshed, which is the old behaviour. The "CLI supports it" test also now calls `instance.snapshot()` first, so the version floor is what admits the flag; without it the driver saw a null version and would have pushed the flag for any CLI, passing for the wrong reason. **The room dedup compared the wrong spelling.** Requests and results reach the transcript inside a JSON envelope (roomHandoffReport), so anything with a newline appears escaped there. `roomContext.includes(child.result)` could never match a multi-line result, so the brief was re-appended on top of a transcript that already carried it — the exact duplication this check exists to prevent. It now compares both spellings, and the fixture result is multi-line so the case is actually covered. Mutation-checked all three: - floor raised above 2.1.267 → the "supports it" test fails (flag absent) - floor dropped to 0 → the "old CLI" test fails (flag pushed when it must not be) - dedup reverted to a raw compare → the brief duplicates (length 2, not 1) typecheck, lint green; claude, direct-coordination, room-coordination and thread-aware-bots suites 169 passed.

🟠 Major · Fix: turnContext is deleted before the bot branch reads it, so the recorded context figure is always lost. · server/index.ts:4268-4269
4268-4269: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick winFix:
turnContextis deleted before the bot branch reads it, so the recorded context figure is always lost.At Line 4227,
turnContext.delete(event.threadId)runs unconditionally for everyturn.completedevent, before theif (bot)branch executes. At Line 4268, that same branch callsturnContext.get(event.threadId)to readlastContext— but the entry for this thread was already deleted at Line 4227, solastContextis alwaysundefined. Nothread.token-usage.updatedevent can run between those two points inside oneturn.completedhandler invocation, so the value is never repopulated.As a result,
context.tokenspassed tostore.addTaskUsage(Line 4276) is alwaysundefined, andcontext.windowalways falls back tomodelContextWindow(contextModel). The per-turn context-token tracking this PR adds tocontracts.tsnever reaches the task usage record for direct (1:1) turns.Compare with
turnUsage/lastReportedright above: that value is captured into a local variable before the map entry is deleted. Apply the same pattern toturnContext.🐛 Proposed fix
const lastReported = turnUsage.get(event.threadId); turnUsage.delete(event.threadId); - turnContext.delete(event.threadId); + const lastContext = turnContext.get(event.threadId); + turnContext.delete(event.threadId); // group turns run on the room's thread — the speaking bot's taskconst tokens = event.usage ?? lastReported; // the context figure: what the last model call's prompt held, with // the window from the driver or, failing that, the model's family - const lastContext = turnContext.get(event.threadId); - turnContext.delete(event.threadId); const contextModel = store.taskByThread(bot.id, event.threadId)?.modelSelection?.model ?? bot.modelSelection.model;🤖 Prompt for AI Agents

not treated as supported; distinguish initial null discovery from a completed

latter. Ensure resumed refresh turns without snapshot() do not add
--system-prompt-snapshot, and add coverage for that path while keeping existing
tests unchanged in intent.

What changed
--system-prompt-snapshot off. If a headless turn starts before the Engines page checks the installed CLI version, probe--versionfirst so an older CLI never receives the unsupported flag. This also refreshes pair conversations created before the fix, whose original system snapshot may already contain the first assignment.Why
Claude Code snapshots the system prompt on a session's first request. Reusing a direct pair conversation meant later
coordinate_botsassignments were present only in a system prompt update that Claude ignored on--resume, so the teammate repeated the first assignment.Fixes #1232.
