TASK-721, first slice. The stalled-connect nudge now names the Terminal command a person missed when they copied only the MCP snippet.

Change

• markByoCommandCopied also records the first copy of each kind: onboarding.byoMcpCopiedAt and onboarding.byoCliCopiedAt. The existing byoCommandCopiedAt / byoCommandType pair is unchanged. The in-memory guard that skipped a second kind is now per kind, so MCP-then-listener no longer reads as MCP-only.
• composeStalledConnectNudge takes the per-kind times. MCP copied and listener command never copied gives: "you copied the MCP command …, but not the Terminal command that starts me", then the run command. When the listener command was copied too, the existing listener wording applies. A signup that only has the older pair keeps the older wording.

Not in this PR

• The nudge still fires only on deriveAgentState = never-connected, which reads lastUsedAt. An MCP tool call therefore still suppresses it. Moving that to listener check-ins needs the installation-token stamp and a backfill, and is waiting on a ruling.
• The Bring your own page copy is TASK-720's file.

Tests

• Each kind is written once however often it is copied; a failed per-kind write retries.
• MCP-only names the Terminal command. MCP plus listener does not. Older signups keep the older text.
• Mutation-checked: disabling the MCP-only branch fails its test, and ignoring cliCopiedAt fails the both-copied test.

Walkthrough

The onboarding data model now records MCP and CLI command copies separately. The stalled-connect service passes those timestamps to the nudge composer, which uses copy evidence to select nudge wording.

Changes: Command-copy tracking and stalled-connect nudges

Layer / File(s)	Summary
Per-kind command-copy tracking backend/models/User.ts, backend/services/onboardingMarks.ts, backend/__tests__/unit/services/onboardingMarks.test.js	The onboarding model and schema add separate MCP and CLI copy timestamps. The marking service writes each timestamp once per user and command kind. Tests cover per-kind writes, deduplication, retries, and reset behavior.
Per-kind stalled-connect nudge evidence backend/services/stalledConnectService.ts, backend/services/stalledConnectCopy.ts, backend/__tests__/unit/services/stalledConnectService.test.js, docs/runbooks/new-signup-stall.md	The service forwards the per-kind timestamps to the nudge composer. The composer uses per-kind and legacy evidence, token timing, and opened operating system to select nudge wording. Tests cover these cases, and the runbook documents the recorded marks and timing rules.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Reviewed head 4673cb7.

Three read-only Opus passes on the same subagent. The first two returned HOLD and I fixed what they found; the third passed at this head.

Fixed along the way:

• A listener copy made before the per-kind marks shipped no longer reads as "never copied" when an MCP copy follows.
• A per-kind copy counts for this nudge only when it falls at or after the stalled token was issued.
• "But not the listener command" is said only when no listener copy exists at all. An older listener copy with an in-episode MCP copy gets the neutral MCP wording.
• A Linux or Windows browser is not told it missed a command its page never showed.
• An unparseable per-kind time falls back to the first-copy pair.

Checked at this head: the full truth table of listener and MCP copies (none, before the token, inside it), legacy-only signups keep main's wording byte for byte, and a missing tokenIssuedAt or null commandType gives no false claim. Both new tests per fix fail when the fix is reverted, and I mutation-checked three of them.

Known limits, not blocking: the marks are per person, so a listener copy for another agent inside this token's window is credited to this seat. A failed listener-copy write that is never retried could make the "not the listener command" sentence false.

Not in this PR: the nudge still fires only on never-connected, which reads lastUsedAt. That change waits on a ruling.

Do not treat missing cliCopiedAt as proof of MCP-only history.

Do not treat missing cliCopiedAt as proof of MCP-only history.

Use legacy byoCommandType: 'cli' as CLI evidence for both mcpOnly and effective command selection. However, this alone does not solve compatibility. A legacy MCP-first user could copy CLI before per-kind tracking, then copy MCP afterward. That record has byoCommandType: 'mcp', mcpCopiedAt, and no cliCopiedAt, so it is indistinguishable from a true MCP-only record.

Represent this historical CLI status as unknown, or use conservative wording for legacy MCP-first records. Emit “but not the Terminal command” only when the complete copy history supports that conclusion. Add tests for both mixed legacy/new cases.

Do not treat a failed CLI mark as proof that the Terminal command was not copied.

If the CLI-specific User.updateOne(...) rejects, the catch only clears the in-process deduplication key. The stalled-connect query then sees MCP evidence without CLI evidence and can post the false MCP-only nudge. The only visible retry is a later copy event.

Retry the failed per-kind write before using its absence in nudge wording, or preserve unknown evidence and use the legacy wording until the write succeeds.

Add a real-model write-once round-trip for each command kind.

197-238: Trivial · Data Integrity & Integration · Quick win

Add a real-model write-once round-trip for each command kind.

The tests assert the $exists: false filter and update-call count, but they never store the first timestamp, reset the deduplication state, call markByoCommandCopied again, and compare the persisted value. They would catch a direct removal of the asserted filter, but they do not verify the persisted write-once behavior.

The repository test guidance requires a real-model round-trip for new stored fields. Add that coverage for byoMcpCopiedAt and byoCliCopiedAt.
