Settle open docs claims, point In flight at the tracker, record the Store grant (steward cycle 2) - #300

Docs and plans steward, cycle 2 (#290). Docs only. This settles claims that cycle 1 recorded as unverified, and follows two of Val's answers there.

• modex-signin.md: port 43821 is only the default callback registered with WorkOS. The listener has used a system-assigned port since Add native Modex sign-in with GitHub through WorkOS #141 (workos-auth.ts, listen(0)), and the 127.0.0.1:* wildcard covers it. The doc now says so, so nobody expects Modex on 43821.
• auto-routing.md: unknown models fall back to tier 2 of 0–3 (routing/catalog.ts, tierOf). "The middle tier" was ambiguous on a four-rung ladder.
• update-recovery.md: the verification paragraph's counts come from the 2026-10-12 run it links, so it now gives that date.
• status.md In flight (Val's decision on [Tracker] Docs and plans steward #290): the native conversation fidelity entry no longer lists open CF PRs by number. That list went stale within hours: it still named Keep failed Claude turns owned through Stop (CF-2 repair) #291, which merged into Make Claude Stop truthful on claude -p: native interrupt, bounded exit, withdrawn prompts (CF-2) #286, and missed Preserve typed conversation fidelity and streaming reader state #295, Wait for the evidence turn to render before unfolding it (e2e race) #297, test: reconcile CF-2 evidence checks with current main #298 and Show and copy the lines a Codex memory citation points to (CF-5) #299. It now says the tracker's child issues link their open PRs, which GitHub keeps current.
• GUI Connect grant attribution (Val's answer on [Tracker] Docs and plans steward #290): the grant from the October 11 signed Store run came from Val's own manual testing. The signed-acceptance review gains a dated "Attribution resolved" section, and the Store and Companion readiness reviews each gain a one-line dated note pointing to it; their original text is unchanged. status.md's Store Open list drops the item. The Cancel check stays open.

Checked and left unchanged:

• analytics.md's demo figures match what usage/sample.ts produces when run: 471 calls, 147 sessions, 45 days, 11 sources, January–September, 212 unpriced.
• pages-maintenance.md is right that running Codex threads keep their tools until the app-server restarts. codex.ts sends the MCP config only on thread/start, or on thread/resume for a thread that isn't loaded yet.

Verification

• A relative-link and anchor check over every Markdown file passes. Three hits are example paths inside inline code.
• pnpm build && pnpm test passed locally with no failures. Root suites: 109 and 16. Desktop: 1,523 passed and 16 skipped of 1,539, then 21. The remaining workspace suites: 10 and 16.
