What issue are you seeing?

The Codex App appears to display an inflated thread total count.
In my local app/state, I saw a displayed thread total of 11. After inspecting local Codex state files, the number appears to be calculated as a raw sum of two sources:

~/.codex/state_5.sqlite
threads table count: 5

~/.codex/.codex-global-state.json
projectless-thread-ids count: 6

Displayed total: 5 + 6 = 11

However, these two sources are not disjoint. In my case, 3 thread ids appear in both sources.
The unique thread count across those sources is therefore:

5 + 6 - 3 overlapping ids = 8 unique thread ids

So the displayed total appears to double-count some projectless threads.
I also tested deleting one rollout/session file under:

~/.codex/sessions/

The displayed thread total did not change from 11, which suggests the count is coming from app/index state rather than the actual session files.
PII redacted example of the local counts:

state_5.sqlite threads:
- count: 5
- one row had rollout_exists = false after I deleted one session file

.codex-global-state.json projectless-thread-ids:
- count: 6

overlap between the two sets:
- count: 3

unique ids across both:
- count: 8

displayed total:
- 11

What steps can reproduce the bug?

1. Open Codex App and note the displayed thread total count.
2. Inspect local thread state:

sqlite3 ~/.codex/state_5.sqlite 'select count(*) from threads;'

1. Inspect projectless thread ids in:

~/.codex/.codex-global-state.json

Specifically check:

projectless-thread-ids

1. Compare:

• threads table row count
• projectless-thread-ids count
• overlap between the two id sets
• displayed total in the app

1. Optional additional check:

• Delete or move one rollout file under ~/.codex/sessions/
• Restart or refresh Codex App
• Observe that the displayed total may remain unchanged because the index/app state still contains the thread metadata.

1. In my case:

threads table count: 5
projectless-thread-ids count: 6
overlap: 3
unique thread ids: 8
displayed total: 11

What is the expected behavior?

The displayed thread total should either:

1. Count unique thread ids after deduplicating across local app/index state sources, or
2. Clarify in the UI that the number is a raw indexed-record count rather than a unique visible thread count.

If the UI label says “thread total”, I would expect it to represent the number of unique threads visible/managed by the app, not threads table count + projectless-thread-ids count with duplicates included.
