fix(server): worktree thread lookups match any spelling of the path - #36802
getShellSnapshot({ worktreePath }) now finds threads whose stored worktreePath is another spelling of the same checkout (trailing slash, backslashes, Windows case). It uses a loose SQL prefilter backed by a new expression index (migration 092, so the read still avoids a table scan), then keeps only exact matches by normalizeProjectPathForComparison, so POSIX paths keep their case. Keeps occupancy checks from missing an idle occupant stored under an alias. Author's three commits, with conflicts resolved to their own merge with main.
Supersedes #29792. The change is @saphid's; their commits are kept.
Main's shell read must not scan every thread. ASCII path queries use an indexed normalized key; a query with a non-ASCII character still admits those stored paths for the exact comparison.
Macroscope's review found this PR approvable — Worktree thread lookups now normalize path spellings, with an indexed SQL filter and an exact application-side comparison. The change is limited to lookup behavior and an additive index; the reported edge cases concern missed matches rather than material data exposure.

Walkthrough
Shell snapshot filtering now compares normalized worktree paths, and migration 092 adds a normalized worktree-path index. Thread deletion now accounts for side chats when checking whether a worktree has remaining users.
Shell snapshot rows include worktree paths. Filtering normalizes paths before comparison. Tests cover trailing separators, POSIX case sensitivity, and Windows-style paths.
Worktree path index and migration registration apps/server/src/persistence/Migrations/092_WorktreePathKeyIndex.ts, apps/server/src/persistence/Migrations.ts, apps/server/src/persistence/reconcileV2PreviewMigration.test.ts
Migration 092 creates an index based on normalized worktreePath values in valid JSON. The migration registry and migration-result expectations include migration 92.
Deletion includes the target thread’s side chats in the removed-thread set. The set is used when checking surviving threads and server-reported worktree occupants. Tests cover side-chat lineage and deletion requests.
Worktree occupancy lookups now find threads stored under alternate spellings of the same path. Two rare edge cases remain: whitespace other than spaces around the requested path, and a stored Unicode character that lowercases to ASCII. In those cases an existing occupant can be missed, so the owner should be aware of them. The risk is low and nothing here should block merge.

Explanation
The title names the main change: worktree thread lookups in the server now match any spelling of a path. The change is a fix to getShellSnapshot({ worktreePath }) in the orchestration projection store. The title uses a conventional commit prefix, is one sentence, and is specific.
Full details: Description check
Explanation
The description covers the problem (threads with aliased worktree paths missed by lookups and occupancy checks), the change (loose SQL prefilter, new migration 092 expression index, exact comparison with normalizeProjectPathForComparison), and the linked context (supersedes #29792, layer 2 of 2 on #36800). It omits the required Scope section content: it does not link a bug issue or explain why no issue is needed. The Verification section is missing entirely: it does not list focused tests or manual checks, or the observed results. The template's CONTRIBUTING.md note and the agent/model attribution line are also absent. The description also does not state the web-side side-chat deletion change that the commits include.
Resolution
Add a Verification section that lists the focused tests run (for example, the ProjectionStore shell snapshot tests and the reconcileV2PreviewMigration test) and their observed results, and state anything not checked. Add a Scope section that links the bug issue or explains why a small fix needs no issue. Mention the useThreadActions side-chat deletion change, or split it into its own PR, since the template asks for one underlying problem per PR. If an agent did the work, end with the model and harness used.

separate worktreeThreadIds query mock that returns the parent and side-chat IDs,
so the enabled-capability case exercises the server-reported-occupants

Match JavaScript whitespace trimming in the SQL key.
With a stored path /repo/wt and query "\t/repo/wt\n", normalizeProjectPathForComparison considers both paths equal. SQLite's default trim() removes spaces, not tabs or newlines. The ASCII query also disables the fallback, so SQL discards the thread before the exact comparison. (www3.sqlite.org)
Use the JavaScript whitespace set for both SQL keys and the matching index expression. Extend the existing service test with this case.

Preserve Unicode-to-ASCII matches for ASCII queries.
With a stored path C:/K/wt and query c:/k/wt, the JavaScript comparator produces equal keys because Unicode lowercase maps K to k. (262.ecma-international.org) SQLite's ASCII-only lower() leaves K unchanged. Because the query is ASCII, this branch omits the fallback and loses the matching thread. (www3.sqlite.org)
Make the fallback cover stored characters that lowercase to ASCII, even when the query is ASCII. Extend the existing Windows assertion with this query direction.

Extend this case to exercise server-reported occupants.
This test inherits shellThreadFamilies=false, so it never exercises the changed predicate at Line 531. Reverting that predicate would leave this test passing.
Parameterize this case over both capability values. Add a distinct worktreeThreadIds query mock that returns the parent and side-chat IDs. The current fallback returns session data, so enabling the capability alone will not exercise the branch correctly.
As per coding guidelines, “Extend before you add” and request coverage only when it “would catch a real regression.” As per path instructions, use “the fewest tests that fail on main for that reason.”

The automated pipeline stopped on this pull request and will not merge it:
the capture step could not show the problem on the base commit, so there is nothing to prove fixed.
Create a project, a parent conversation waiting for input, and thread A in a new worktree. Create a replay child through delegated_task.request, wait for completion, then assign A's worktree path plus a trailing slash through thread.metadata.update. Keep the parent unopened during setup. Open A by link, choose Delete, confirm, capture the result and assert that 'Delete the worktree too?' is absent. Both commits completed these steps without that prompt. After the first complete base run passed, the scenario was corrected once to avoid opening the parent; base still passed. The runner exited 1: not proven.
