--from-${source} cannot be combined with --continue, --resum

Error message

--from-${source} cannot be combined with --continue, --resume, or --fork

What it means

A foreign session import selects a fresh session source and therefore cannot be combined with the session-selection flags --continue, --resume, or --fork. resolveForeignSessionSource throws when any of those is present together with --from-claude/--from-codex.

Solutions

Drop --continue/--resume/--fork when importing; run the import first, then resume normally.
If the goal is to continue a Claude/Codex conversation, pick it via `omp --resume` after importing once.

Example fix

// before
omp --from-claude --continue
// after
omp --from-claude   # then: omp --continue

Defensive patterns

Strategy: validation

Validate before calling

const hasImport = process.argv.some(a => a === "--from-claude" || a === "--from-codex");
const hasSelector = process.argv.some(a => ["--continue","--resume","--fork"].some(f => a === f || a.startsWith(f + "=")));
if (hasImport && hasSelector) throw new Error("Import and session selection are separate steps");

Prevention

Run the import as its own command; resume/fork in a follow-up invocation.
Avoid templating --continue/--resume into every launch script.
Remember imports create a NEW session — there is nothing to continue in the same run.

When it happens

Trigger: Running e.g. `omp --from-claude --resume` or `omp --from-codex --fork <id>` — both an import source and a local session selector were requested.

Common situations: Users trying to continue an imported conversation in one command; muscle memory of always resuming with --continue; scripts templating --resume into every invocation.
