TML-3097/TML-3096: migration plan warns on stale db ref and requires consent for destructive auto-baselines; migration new --from errors on empty graph and ambiguous prefix - #30084
Conversation
…w --from resolution migration plan: warn when the default db-ref origin is behind the graph tip, require destructive-changes consent before writing an auto-baseline package, and include baseline-leg operations in the plan result so the destructive warn-summary covers them. migration new: error when --from is passed on an empty migrations directory, and error on a --from prefix matching several migration target hashes.

📝 WalkthroughWalkthroughChangesThe migration CLI now validates explicit Migration workflows
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The migration command changes improve stale-reference warnings, destructive-baseline consent, and --from validation, but an explicit empty --from can still produce an incorrect no-changes result, malformed consent metadata can fail during confirmation, and baseline-only output can show the wrong directory. The PR is mergeable with explicit owner awareness and follow-up on these bounded issues. Sequence Diagram(s)sequenceDiagram

…wo-package plan output Review fixes: the destructive-baseline consent check now sees the operations that resolved even when a placeholder rejected (Promise.allSettled), so a placeholder cannot smuggle a destructive baseline past the prompt; the default-origin tip lookup treats any graph-shape error as "no unambiguous tip" instead of dying with CLI.UNEXPECTED on corrupted graphs; the consented re-run carries the extension dirs the refused first run seeded so the result describes the whole invocation; the two-package preview and summary now cover the baseline leg, and each operation is attributed to its package directory in the JSON result and the rendered tree; --from "" is treated as a prefix instead of silently defaulting; the consent verdict is a typed interface read with blindCast; the consent question shares its operation-list formatting with db update and the consent-operations-missing error names the right preview command.

Use baselineDir when the plan writes only a baseline package.
A baseline-only result has no dir and does not set packageDir on its operations. Line 72 then labels the tree root as operations, not as the written baseline directory. Fall back to result.baselineDir before operations, and add a baseline-only presentation assertion.
