What & why

A terminal URL ending in / could absorb the next log line's prefix, extending its underline and changing the destination. For example, http://localhost:3001/ became http://localhost:3001/sloyd-web:dev:localhost.

Replace newline-guessing with terminal wrap metadata and map URL ranges to actual terminal cells, including wide characters, combining marks, and early wrapping. Adapt VS Code's URL parser for IPv6, quotes, Markdown delimiters, and international paths. Bound scanning while supporting URLs across more than three rows.

Explicit newlines now stop inferred URLs. TUIs that split URLs with explicit newlines should emit OSC 8 hyperlinks; genuine terminal wrapping remains supported. Existing file-link and OSC 8 handlers remain in place.

The verification report includes upstream revisions, all before/after case results, and the implementation tradeoffs. Generated report files are excluded from the code diff; the published page retains the evidence.

How I tested it

• 3,551 URL cases pass using real xterm buffers. The original 3,545-case suite had 503 passes and 3,042 failures before this PR; many failures share the range-boundary bug. Six additional regression cases reproduce and fix leaked bracket context between URLs.
• 605 related link tests pass, covering local-link parsing, resolution, adapters, and manager lifecycle.
• Repository-wide bun run lint and bun run typecheck pass (42 typecheck tasks). bun run check:plugins and git diff --check pass.
• The earlier local repository-wide bun run test stopped at the desktop suite: 7,531 pass, 22 fail. Failures are in untouched Git/worktree and shell-environment suites, including external worktree import, branch detection, hook tolerance, and shell environment capture. No link tests failed. All GitHub CI checks, including Test and Build, subsequently passed on the initial PR revision.
• Real mouse hover and click in a browser xterm component harness reproduced the malformed destination before and the correct destination after. This is component verification, not signed-in desktop E2E; no matching dev renderer was running for this worktree.
• Verified the report offline, including embedded screenshots, filtering, and mobile layout.

• bun run lint and bun run typecheck pass (CI fails on lint warnings too)

Summary by cubic

Fixes terminal URL highlighting so a URL ending in / no longer absorbs the next log line's prefix, which previously extended the underline and changed the destination from http://localhost:3001/ to http://localhost:3001/sloyd-web:dev:localhost.

• Replaces the hard-wrap guessing in multi-line-link-provider with xterm wrap metadata and cell-level ranges that handle wide characters, combining marks, and early wrapping.
• Explicit newlines now end URL matches; TUIs that split URLs with explicit newlines should emit OSC 8 hyperlinks instead.
• Adapts VS Code's URL link parser for IPv6, quotes, Markdown delimiters, and international paths.
• Resets bracket context between URLs so an unterminated bracket can't make a later URL absorb trailing prose.
• 3,551 URL cases pass against real xterm buffers, up from 503; the 22 remaining repo test failures are in untouched Git/worktree and shell-environment suites.

📝 Walkthrough

Walkthrough

The terminal URL provider now uses a local state-machine parser and direct xterm buffer mapping. The multiline provider was removed. Tests now use headless xterm buffers and cover wrapping, coordinates, delimiters, callbacks, limits, and malformed URLs.

Changes

Terminal URL provider

Layer / File(s)	Summary
URL parser implementation apps/desktop/.../link-providers/utils/url-parser/*	Adds a state-machine parser for URL schemes, delimiters, nested brackets, termination rules, and link ranges.
Terminal buffer integration apps/desktop/.../link-providers/multi-line-link-provider.ts, apps/desktop/.../link-providers/url-link-provider.ts, apps/desktop/.../link-providers/index.ts, apps/desktop/src/renderer/lib/terminal/terminal-link-manager.ts	Removes the multiline provider and rewrites UrlLinkProvider to reconstruct wrapped xterm text, apply HTTP(S) validation and length limits, map links to terminal coordinates, and retain callbacks.
Provider fixtures and tests apps/desktop/.../link-providers/url-link-fixtures.json, apps/desktop/.../link-providers/url-link-provider.test.ts	Adds URL fixtures and headless terminal coverage for extraction, wrapping, coordinates, callbacks, malformed input, limits, and performance.
Verification artifacts reports/terminal-links/*	Adds documentation and JSON results for browser evidence, page verification, and test verification.

Merge Risk: 🔵 Low · up to 4c117

A malformed URL can cause a later terminal link to include unrelated text. The localized parser-state fix should be applied before merging.

- Around line 381-390: Reset inSquareBrackets to false inside the
resetStateMachine block alongside the other delimiter state flags, so restarting
URL parsing cannot leak square-bracket context into later links. Update the
state-reset logic near state, hasOpenParens, and hasOpenSquareBracket while
preserving the existing link-start tracking.
