v1 didn't track is_group separately; db.ts hardcoded `is_group: 1` for
every messaging_group. v2 uses is_group=0 to collapse DM sub-thread
sessions and to drive routing decisions, so getting it wrong is latent
risk on otherwise-working installs.
New helper inferIsGroup(channelType, platformId) lives in shared.ts so
tasks.ts and any future migration step can reuse it. Inferred per
channel:
- whatsapp: `<id>@g.us` is a group, anything else is a DM
- telegram: negative chat IDs are groups, positive are DMs
- everything else: default to 1 (least surprising for chats v1 chose
to register, where DM auto-create paths weren't used)

- shared.ts: parseJid now recognizes raw Baileys WhatsApp JIDs
(`<id>@s.whatsapp.net`, `@g.us`, etc.); v2PlatformId returns the raw
JID for whatsapp to match what the runtime adapter emits. Without this,
every WhatsApp group in a v1 install was silently skipped.
- discord-resolver.ts: new helper that uses DISCORD_BOT_TOKEN to look up
channelId → guildId via the Discord API, since v1 stored only the
channel id but v2 needs `discord:<guildId>:<channelId>`. Best-effort:
on missing/invalid token or network error, returns empty resolver and
the affected groups are skipped with the reason surfaced per channel.
- db.ts, tasks.ts: route Discord groups through the resolver; other
channels go through v2PlatformId unchanged. Resolver only built when
at least one Discord group exists, so non-Discord installs incur no
network.
- db.ts: when every v1 group is skipped, exit non-zero with a FAIL line
instead of `OK:groups=N,...,skipped=N`, so the wrapper doesn't hide
total failure under a successful-looking summary.
- migrate-v2.sh: run_step now surfaces ERROR: lines from successful
steps (with count + first 3 + raw log path); phase 2c install loop
populates STEP_RESULTS so install failures show in handoff.json
instead of silently passing.
- sessions.ts: copyTree skips dangling symlinks (e.g. v1's
`.claude/debug/latest`) instead of crashing the entire step.

Extracted the helpers we use (JID parsing, trigger mapping, channel
auth registry, generateId, v2PlatformId) into setup/migrate-v2/shared.ts.
Deleted setup/migrate-v1/ entirely — no code references it anymore.
Updated README, CLAUDE.md, docs/v1-to-v2-changes.md, and
docs/migration-dev.md to reference the new paths and migrate-v2.sh
entry point.
