Replace the error-page bug-report placeholder link

Plan 005: Replace the error-page report placeholder

Executor: follow every step and verification gate. Modify only listed files. Stop and report if a STOP condition occurs.

Status

• Priority: P2
• Effort: S
• Risk: LOW
• Depends on: none
• Category: bug/dx
• Planned at: commit c16bc4f, 2026-07-16

Why this matters

The global error page tells users to create a bug issue, but the anchor points to href="TODO". The support path is therefore non-functional when a user most needs it.

Current state

• app/error.vue:48-54 renders a new-tab link with href="TODO".
• The link is presented as the bug-report workflow for users encountering errors.
• No issue URL or configurable support destination is defined in the reviewed files.

Commands and expected results

Purpose	Command	Expected result
Lint	pnpm run lint -- app/error.vue	exit 0
Typecheck	pnpm run typecheck	exit 0
Tests	pnpm run test	all relevant tests pass

Scope

In scope:

• app/error.vue
• Runtime/public configuration only if maintainers want the destination environment-configurable
• A focused render test if the repository test setup supports it

Out of scope:

• Redesigning the error page
• Automatically pre-filling issue bodies with potentially sensitive error details

Steps

Step 1: Choose a maintained destination

Use the repository's canonical GitHub issue-new URL or an environment-configured support URL. Prefer a stable URL and avoid embedding runtime error details in a public query string.

Verify: Link opens the intended public issue/support page in a new tab.

Step 2: Add a regression check

Test or statically validate that the rendered link is not a placeholder and retains safe external-link attributes.

Verify: pnpm run lint -- app/error.vue and the focused test pass.

Test plan

• Error page renders a non-placeholder href.
• Link retains target="_blank" and rel="nofollow noopener noreferrer".
• Other status-code rendering remains unchanged.

Done criteria

• Users can reach the intended report workflow
• No TODO placeholder remains in the report link
• Safe external-link attributes remain
• Verification commands pass

STOP conditions

• Maintainers have a different canonical support channel; use it rather than inventing a destination.
• The destination requires authentication or exposes private issue tracking.

Maintenance notes

If the issue URL changes, keep it centralized/configured so the error page does not silently regress.

Issue body

Bug Description

The global error page contains a bug-report link with href="TODO", so users cannot follow the promised reporting workflow.

Evidence

• app/error.vue:48-54

Expected Behavior

The link opens the repository's maintained public bug-report workflow.

Acceptance Criteria

• Replace the placeholder with the canonical destination.
• Preserve safe external-link attributes.
• Add a focused regression check or equivalent validation.
• Lint/typecheck/tests pass.
