Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to Session import can reuse the wrong project directory when configuration or project paths contain certain delimiter characters, causing incorrect session placement. The risk is localized and mergeable with explicit owner awareness or a follow-up fix and isolation test. Sequence Diagram(s)sequenceDiagram

- Around line 217-224: Update importNumberPattern in the session import logic to
match imported-title suffixes case-insensitively, aligning it with
searchSessionsByCustomTitle so existing titles such as FIRST (Imported 2)
reserve their suffix. Add coverage for an existing title that differs only by
case.
- Line 82: Define a SerializedUserMessage intersection type from
SerializedMessage and the user-message discriminator, then use it in
deriveFirstPrompt and the find type predicate. Replace both any casts with
type-safe narrowing while preserving the existing first-user-message content
access.

Use an unambiguous memoization key.
Line 446 joins both key dimensions with :. For example, CLAUDE_CONFIG_DIR='/tmp/a' with projectDir='b:c' collides with CLAUDE_CONFIG_DIR='/tmp/a:b' and projectDir='c'. The later call can reuse a project directory from the wrong configuration root.
Proposed fix
(projectDir: string) =>
- `${process.env.CLAUDE_CONFIG_DIR ?? ''}:${projectDir}`,
+ JSON.stringify([process.env.CLAUDE_CONFIG_DIR ?? '', projectDir]),
)Add a cache-isolation test with delimiter-containing values.

Adds /session-import and --session-import for bringing a .jsonl transcript in as a new session — migrating a conversation between machines, projects, or config dirs. Ported from claude-code-best/claude-code#1352, with three changes. Active-chain selection, not a file-order copy. Unlike /branch, this walks the newest non-sidechain leaf back via parentUuid, so rewind/branch dead branches are dropped and parallel tool_use structure survives. Only sessionId is rewritten, which avoids collisions when the source session already exists locally. Compact-summary hint points at the SOURCE, not the import. The upstream patch repointed "read the full transcript at:" at the imported file on the premise that the import "carries the full pre-compact chain". It does not: saveMessages nulls parentUuid at a compact boundary, so a compacted session is several disconnected trees, and loadTranscriptFile returns resumable state only (readTranscriptForLoad truncates pre-boundary bytes above 5 MB). A real 6128-line transcript imported 2277 of 4508 messages. Pointing the hint at the import would send the model to a file holding only what it already has; the source still has the history. Upstream's test masked this by building the boundary with parentUuid set, which never happens in practice — the fixture is corrected here. keepAllLeaves on load, so tip selection is uniform. walkChainBeforeParse picks its leaf as the last non-sidechain line in file order and only runs above 5 MB, so leaving it on made a large transcript resolve a different chain than the same conversation when small. The CLI flag reuses the resume machinery rather than duplicating it: the import writes a real session file, then hands the id to the existing resume-by-id path. Works interactively and under --print; --session-import-only prints the id and exits for scripting. getProjectDir's memoize gains a CLAUDE_CONFIG_DIR-aware key (NUL-joined, so no path can alias another's entry) — without it the cache serves a stale project dir when the env var changes. Verified: 105 tests pass; typecheck unchanged at 2632; imports a real 6128-line compacted session and a 159-message linear one with 0 dangling parents and 0 leaked session ids; /session-import driven end-to-end in the TUI; --session-import-only round-trips into -r.
