feat: enable chat sharing by DanielleMaywood · Pull Request #24987 · coder/coder

Re-review of the fix commit (4144eda). 12 of the original 18 findings are fixed; all verified by Netero and the panel. 5 contested findings were evaluated by the panel and closed (author defenses accepted). Two new findings emerged.

The fixes are thorough. The mutation error reset lifecycle is well-designed (ref-gated reset on open, explicit clear before each mutation, two stories covering cross-type and cross-session scenarios). The split-table accessibility fix uses a single semantic table with sticky headers. The prop rename, toast messages, and convention fixes are all clean.

DEREM-20 is a regression introduced by the DEREM-13 fix: isLoading || isFetching causes the input to disable and banner to disappear on every background refetch (tab switch), not just the initial load. Two reviewers converged on this independently.

Severity breakdown: 2 new P3, 1 new Note. No blocking findings.

"Every tab switch triggers this cycle. An admin typing in another user's chat gets their cursor kicked out of the input momentarily." (Mafuuu)
