Summary

5/5 of the upstream catch-up. Conference and talk feedback, the talk dialog and admin nav, fork PRs #198–#203.

feedback   conference and talk forms, admin view, Excel export; talks open once they've finished; Meet the Experts question
agenda     talks open in a dialog with speaker bios and embedded recordings
admin      grouped sidebar nav with a mobile drawer
migrations 0029–0030

New: a fixture conference year for e2e (8652a72). The feedback e2e spec needs a conference whose agenda is published and whose feedback is open, but the stub's real 2026 is only a save-the-date. Rather than tie tests to a real year's config, a test can now opt its browser into a made-up year:

sequenceDiagram
    participant Spec
    participant Worker
    Spec->>Worker: cookie __e2eFixtureConference
    Worker->>Worker: load-context: if not production && E2E_FIXTURE_CONFERENCE=true
    Worker->>Worker: conferences = FIXTURE_CONFERENCES (fixture year only)
    Worker-->>Spec: /agenda/FIXTURE_YEAR with feedback open

Loading

-getYearConfig(year, appConfig)          // read from the static manifest
+getYearConfig(context, year)            // read the request's conferences
+getConferences(context)
+resolveYearConfig(conferences, year, appConfig)   // pure, for code with no request

It works per browser, like __devDateOverride, so the home page and its baselines still render the real conference. Portal-year lookups (map-sessionize, admin.speakers, exhibitor-export) deliberately keep reading conferenceManifest.conferences.

Evidence

• Before: feedback-links.spec.ts fails in the stub because 2026 has no published agenda.
  After: e2e 67 passed. Build, typecheck, lint and unit tests (734 passed) all pass. dev-date-override.test.ts greps the production worker for the fixture cookie name and doesn't find it.
• Visual: pnpm vr 81 passed. The 9 talk-detail-* baselines were regenerated in the container (82944f3), because the talk page is now a dialog with the speaker's bio. Those are the only baselines that change across the whole stack.

Merge Danger

Door: one-way

Adds D1 migrations 0029–0030.

Blast Radius: agenda

The getYearConfig signature change touches about 30 call sites. Forks with their own callers will need to switch to the (context, year) form, and dddperth's next /core-pull will conflict there and in a few tests. Resolve those toward upstream.
