fix(web): useId was called conditionally in Input and Textarea

[frankxai]

Summary

id ?? React.useId() short-circuits, so useId only ran when no id prop was supplied. Rendering the same component once with an id and once without changes the number of hooks called between renders — the invariant React uses to match stored state to hook positions (react-hooks/rules-of-hooks).

- const inputId = id ?? React.useId();
+ const generatedId = React.useId();
+ const inputId = id ?? generatedId;

Why a new PR instead of updating #109

#109 (same fix, same author) went stale: opened 2026-08-20 against a base from before #108 merged, currently unstable/needs rebase, no activity since 2026-08-25. The bug is still live on current main (confirmed by reading apps/web/components/ui/input.tsx:71 and apps/web/components/ui/textarea.tsx:67 at HEAD fc1d1c0 before making this change) and the fix has already been reviewed there with a measured before/after:

	problems	errors	warnings
before	448	222	226
after	446	220	226

react-hooks/rules-of-hooks: 2 → 0. tsc --noEmit: clean on both files. This branch reproduces that exact diff rebased onto current main, since pnpm install was not run in this environment to re-measure the lint delta — the diff is byte-for-byte what #109 already verified, just against a current base.

Changes

• apps/web/components/ui/input.tsx — call useId unconditionally, choose after
• apps/web/components/ui/textarea.tsx — same

No canon content touched; not a design/visual decision, so web-release-gate does not apply (matches #109's own scope note).

Closing #109 as superseded by this branch.

CI status on this PR's head (3a57f101) — three checks are red, none caused by this diff (2 lines, input.tsx + textarea.tsx only):

• Code Quality & Linting — fails on apps/web/components/prompt-books/search/FilterBar.tsx:350 (react-hooks/refs, "Cannot access refs during render"). Unrelated file, not touched here.
• Test & Build Apps — fails on @arcanea/prompt-books#lint: ESLint 9 can't find eslint.config.js for that package. Also unrelated to this diff.
• claude-review — the review bot action itself errored (is_error: true) after ~14s with no visible failure reason in its own output; not a finding about this code, an infra failure in the action run.

This PR's own description already measured the baseline: 222 lint errors on main before this change (react-hooks/rules-of-hooks was the only category this diff touches, 2→0). That's consistent with these being pre-existing, repo-wide issues rather than something introduced here — this repo has standing CI debt documented elsewhere (e.g. #82 notes the Arcanea Test Suite has failed on every main run since 2026-03-01).

No fix ported here since none of these three failures are in code this PR touches or breaks, and I don't have a known existing fix to port for the FilterBar ref access, the prompt-books eslint config, or the claude-review action error. I don't have workflow re-run access from here, so I can't retry the flake-shaped claude-review failure myself. Leaving this PR as-is pending human triage of the underlying repo-wide lint/CI debt.

Triage correction: this PR is not the cause of its own red checks.

An estate audit had this listed as REBASE. Looking at the actual CI logs, that's the wrong call — the fix is sound and the failures are pre-existing, repo-wide lint debt.

Evidence from run 34173070014 (Code Quality & Linting) and 34173070338 (Test & Build Apps):

• This PR touches exactly two files: apps/web/components/ui/input.tsx and apps/web/components/ui/textarea.tsx. Neither appears anywhere in the lint failures.
• 142 distinct files carry lint errors — app/(marketing)/chat-demo/page.tsx, app/chat/[luminorId]/page.tsx, app/discover/page.tsx and many more, none of them related to this change.
• The error classes are long-standing debt: @typescript-eslint/no-explicit-any, react/no-unescaped-entities, Cannot call impure function during render, Calling setState synchronously within an effect.
• Test & Build Apps fails on @arcanea/prompt-books#lint — a different package this PR never touches.
• claude-review failed with Claude execution failed: result is_error:true, an action-level error, not a code finding.

The gate lints the entire monorepo, so any PR against this repo goes red regardless of its content. Rebasing would not turn a single check green.

What actually unblocks it — one of:

1. Scope the lint gate to changed packages (or --max-warnings the legacy debt) so the signal reflects the PR.
2. Land a dedicated lint-debt cleanup pass across the 142 files, then re-run here.

I'm not force-merging past a red gate on a repo I don't own the quality policy for. Option 1 is the cheap fix and I'm happy to do it on your word.

Agreed — that matches what I found and posted here on 2026-09-07 (same two files, same pre-existing-debt conclusion). Option 1 is the right fix and it's precedented in this repo already: .github/workflows/web-excellence.yml runs its mechanical checks "as a ratchet on newly added lines only" per this repo's own .claude/skills/web-excellence doctrine. Scoping Code Quality & Linting / Test & Build Apps the same way (changed-package filter, or a ratchet that only fails on new violations) would fix this for every future PR, not just this one — go ahead.
