fix: preserve cursor position when inserting async references

Capture mention state snapshot before async operations (applyProjectSkill,
applyById) to prevent cursor position issues. Previously, the mention state
could be invalidated during async operations, causing the cursor to land in
the wrong position after inserting skills or plugins.

Changes:
- Add optional mentionSnapshot parameter to replaceMentionWithText()
- Capture mention state before async calls in insertSkillMention()
- Capture mention state before async calls in insertPluginMention()
- Use captured snapshot instead of potentially stale mention state

This ensures the cursor position is calculated from the original mention
context, not from state that may have changed during re-renders triggered
by async operations.

Fixes #3195

+
+1. **Load the skill** by invoking the `od-contribute` skill via the Skill tool. The skill owns the full execution playbook — do not reimplement it inline.
+
+2. **Pass the user input forward**:
+   - If `$ARGUMENTS` is one of `skill`, `design-system`, `i18n`, `docs`, `bug` (or a recognizable Chinese / English equivalent), pre-select that branch and skip the type-picking `AskUserQuestion` in Step 2.
+   - Otherwise, the skill will ask the user via `AskUserQuestion`.
+
+3. **Honor the interactive contract**:
+   - Always run the prerequisite check first (`gh` installed + authed). If it fails, surface the install/auth hint and stop — do not try workarounds.
+   - Always show the preview + require explicit confirmation before pushing or opening any PR/issue.
+   - At the end, print the PR or issue URL on its own line so the user can click through.
+
+Begin by invoking the skill now.

+
+# od-contribute — first-contribution flow for Open Design
+
+Locked to `nexu-io/open-design`. Branches by **contribution type**, not by issue. Replaces the dev-loop with type-specific no-code validators. Designed so a product user with zero coding background can ship a real PR.
+
+## Language
+
+Mirror the user's language in every user-facing message — `AskUserQuestion` labels and descriptions, status updates, error explanations. Detect from their first message; when uncertain, default to English.
+
+**Generated artifacts (PR titles, commit messages, PR/issue body files, branch names) MUST be English** regardless of the user's chat language. GitHub conventions, maintainer review, and search all assume English. The templates under `templates/` are already English — keep them that way when rendering.
+
+Scripts live under `scripts/`. Source the shared helpers from any script:
+
+```bash
+source "$(dirname "$0")/config.sh"
+```
+
+`SKILL_DIR` below = the directory that contains this `SKILL.md`.
+
+---
+
+## Step 1 — Prereq check (always first)
+
+```bash
+bash "$SKILL_DIR/scripts/check-prereqs.sh"
+```
+
+- Exit 0: capture `GH_USER=<login>` from stdout. Default `TARGET_FORK="${GH_USER}/open-design"`.
+- Exit 2: surface the printed install / auth hint **verbatim** and stop. Do not attempt token workarounds.
+
+If `gh repo view "$TARGET_FORK"` fails, ask the user (one `AskUserQuestion`) whether to fork now via `gh repo fork nexu-io/open-design --clone=false`. Default to yes.
+
+## Step 2 — Pick contribution type
+
+Single `AskUserQuestion` (header: "Contribution", multiSelect: false), four options. Translate option labels/descriptions into the user's chat language; the branch routing is unchanged.
+
+1. **🎨 Ship something I made with OD** — _a Skill, Design System, HyperFrame, or template I want to contribute upstream_ → branch `3a`
+2. **🌍 Translate OD docs** — _README / QUICKSTART / CONTRIBUTING into a new language_ → branch `3b`
+3. **📝 Fix docs / write a blog / fix a typo** — _typo fix, dead link, use-case writeup_ → branch `3c`
+4. **🐛 Report a bug** — _something broke; I'll help turn it into a high-quality issue_ → branch `3d` (issue path, no PR)
+
+Each branch below is self-contained. Steps 7–8 (preview + push) are shared across branches `3a`/`3b`/`3c`. Branch `3d` skips them entirely.
+
+---
+
+### Step 3a — OD product submission (Skill / Design System)
+
+**3a.1** Ask user: "What's the local path to the artifact you want to ship?" (single free-text, translated into the user's chat language). Common: a folder path (Skill) or a single `DESIGN.md` file (Design System).
+
+**3a.2** Sniff type:
+
+```bash
+# Skill: folder containing SKILL.md with frontmatter.
+# Design System: file matching DESIGN.md anatomy.
+```
+
+If ambiguous, ask the user to confirm.
+
+**3a.3** Run setup:
+
+```bash
+bash "$SKILL_DIR/scripts/setup-workspace.sh" skill <slug>
+# or
+bash "$SKILL_DIR/scripts/setup-workspace.sh" design-system <slug>
+```
+
+`<slug>` is `od::slugify` of the Skill `name` frontmatter field or of the brand name. Capture `WORKDIR` from stdout.
+
+**3a.4** Copy artifact into workspace at the right target dir:
+- Skill → `$WORKDIR/skills/<slug>/`
+- Design System → `$WORKDIR/design-systems/<brand-slug>/DESIGN.md` (+ any sibling assets in the same folder)
+
+**3a.5** Validate:
+
+```bash
+bash "$SKILL_DIR/scripts/validate-skill-submission.sh" "$WORKDIR/skills/<slug>"
+# or, with 1-2 reference DESIGN.md files passed in:
+bash "$SKILL_DIR/scripts/validate-design-system.sh" \
+  "$WORKDIR/design-systems/<slug>/DESIGN.md" \
+  --reference "$WORKDIR/design-systems/airbnb/DESIGN.md" \
+  --reference "$WORKDIR/design-systems/apple/DESIGN.md"
+```
+
+If validation fails, surface the FAIL lines verbatim, ask the user to fix, retry. **Never push a failing artifact.**
+
+**3a.6** Ask 3 short questions via `AskUserQuestion` (translate the labels into the user's chat language):
+- "What name should we credit you under in the PR?" — free-text
+- "One-line pitch for this Skill / Design System?" — free-text
+- "Path to a screenshot (optional)?" — free-text
+
+**3a.7** Render `templates/PR-BODY-skill.md` (or `PR-BODY-design-system.md`) with substitutions:
+- `{{SKILL_NAME}}`, `{{SKILL_SLUG}}` (or `{{BRAND_NAME}}`, `{{BRAND_SLUG}}`)
+- `{{PITCH}}` (the one-line)
+- `{{MOTIVATION}}` (free-text — agent can offer to draft this from the skill body, but user confirms)
+- `{{TRY_PROMPT}}` (a prompt they recommend trying — agent suggests a default, user confirms)
+- `{{SCREENSHOT_BLOCK}}` (Markdown image block if a screenshot path was given, else empty)
+- `{{DISCORD_INVITE}}` from `$OD_DISCORD_INVITE`
+
+Write to `$WORKDIR/.od-contrib/PR-BODY.md`.
+
+→ Jump to **Step 7**.
+
+---
+
+### Step 3b — i18n translation
+
+**3b.1** Setup workspace (slug = `translate-<doc>-<lang>` if known, else `translate`):
+
+```bash
+bash "$SKILL_DIR/scripts/setup-workspace.sh" i18n translate
+# capture WORKDIR
+```
+
+**3b.2** Discover gaps:
+
+```bash
+bash "$SKILL_DIR/scripts/discover-i18n-gaps.sh" "$WORKDIR" > /tmp/od-i18n-gaps.json
+```
+
+Each line is JSON. Rank by:
+- `status: "missing"` first (missing language is highest leverage)
+- then `status: "stale"` ordered by `english_commits_since_translation` desc
+- README family before QUICKSTART before CONTRIBUTING
+
+**3b.3** Take the top 3–4 gaps and present via `AskUserQuestion` (header: "Translation target"). Each option label like: `README → 한국어 (Korean)` / `QUICKSTART (zh-CN) refresh — 12 commits behind`. Translate the header text into the user's chat language but keep the option labels descriptive (the language names belong in their native script).
+
+**3b.4** Once user picks, **rename branch** to be specific:
+```bash
+git -C "$WORKDIR" branch -m "od-contrib/i18n/<doc>-<lang>-<date>"
+```
+(or pre-set the slug in step 3b.1 if the user confirmed earlier.)
+
+**3b.5** Translate. Read the English source. Translate **structure-preserving**:
+- Code blocks: leave untranslated
+- Brand / product names: leave untranslated
+- Filenames in inline code: leave untranslated
+- Image / link targets: leave untranslated; if a localized version of a linked doc exists, swap the link to the localized file
+- Headings: translate, keep the heading depth identical
+- Tables: translate cell text only, keep alignment / pipes
+
+Write the result to `$WORKDIR/<TRANSLATED_PATH>` (e.g. `QUICKSTART.es.md`). Show user a unified diff vs. the English source for visual sanity-check (line-count delta within ±15% is a healthy signal).
+
+**3b.6** Validate the translated file against the English source. The `--reference` flag tells the validator to ignore relative refs that were already broken in the source — OD docs frequently link to website route slugs (e.g. `skills/blog-post/`) that aren't files on disk; we don't want a structure-preserving translation to fail because of pre-existing dead refs.
+
+```bash
+bash "$SKILL_DIR/scripts/validate-markdown.sh" \
+  "$WORKDIR/<TRANSLATED_PATH>" \
+  --reference "$WORKDIR/<ENGLISH_PATH>"
+```
+
+If FAIL → surface verbatim, fix, retry.
+
+**3b.7** Render `templates/PR-BODY-i18n.md` with `{{DOC_NAME}}`, `{{LANG_DISPLAY_NAME}}`, `{{LANG_CODE}}`, `{{TRANSLATED_PATH}}`, `{{ENGLISH_PATH}}`, `{{STATUS}}`, `{{TRANSLATION_NOTES}}` (one paragraph from the agent: anything tricky, untranslated terms it kept, etc.), `{{DISCORD_INVITE}}`.
+
+→ **Step 7**.
+
+---
+
+### Step 3c — Docs / blog / typo
+
+**3c.1** Setup workspace (slug `docs`):
+
+```bash
+bash "$SKILL_DIR/scripts/setup-workspace.sh" docs <slug>
+```
+
+**3c.2** Ask user (one `AskUserQuestion`):
+1. **Auto-discover small fixes** (run discover-doc-gaps, pick something)
+2. **I have a specific fix in mind** (free-text)
+3. **I want to write a blog / case study** (free-text — what's the use case?)
+
+**3c.3 (Auto-discover branch)** Run:
+
+```bash
+bash "$SKILL_DIR/scripts/discover-doc-gaps.sh" "$WORKDIR" > /tmp/od-doc-gaps.json
+```
+
+Group by `kind` (typo / deadlink / todo). Show the user up to 6 candidates via `AskUserQuestion`. Once picked, apply the fix in code (typo: replace word; deadlink: ask user for the new URL; todo: that's a proper task, ask user to write the missing prose).
+
+**3c.4 (Specific-fix branch)** Read the file, apply user's described change. Confirm via diff.
+
+**3c.5 (Blog branch)** First check whether OD has a blog directory:
+
+```bash
+ls "$WORKDIR/docs" 2>/dev/null
+```
+
+If a `docs/blog/` or similar exists, place the new post there. If not, ask the user where it should live, defaulting to `docs/<slug>.md`. Generate an outline → user fills in user-specific bits (their use case, screenshots, the prompt they used, the rendered output) → agent stitches into a final Markdown.
+
+**3c.6** Validate every changed/added file. For files that already exist in the repo (typo fix, dead-link fix, doc edit), pass `--reference` pointing at HEAD's version so we only fail on relative refs the user *introduced*, not on pre-existing route slugs:
+
+```bash
+# For modifications to existing files:
+git -C "$WORKDIR" show "HEAD:<path>" > "/tmp/od-contrib-orig-<basename>" 2>/dev/null
+bash "$SKILL_DIR/scripts/validate-markdown.sh" \
+  "$WORKDIR/<changed-path>" \
+  --reference "/tmp/od-contrib-orig-<basename>"
+
+# For brand-new files (e.g. a blog post the user is creating from scratch),
+# omit --reference. The validator will skip the relative-ref check entirely
+# (since it can't tell route slugs from real paths in isolation).
+```
+
+**3c.7** Render `templates/PR-BODY-docs.md` with `{{ONE_LINE_SUMMARY}}`, `{{DETAILS}}`, `{{FILES_LIST}}`, `{{DISCORD_INVITE}}`.
+
+→ **Step 7**.
+
+---
+
+### Step 3d — Bug report (issue path, no PR)
+
+**3d.1** Read OD's actual schema at runtime to make sure we mirror it:
+
+```bash
+gh api "repos/${TARGET_REPO}/contents/.github/ISSUE_TEMPLATE/bug-report.yml" --jq .content | base64 -d > /tmp/od-bug-report.yml
+```
+
+If the schema has drifted from the template (`templates/ISSUE-BODY-bug.md`), regenerate the body to match.
+
+**3d.2** Ask the user via `AskUserQuestion`, one structured prompt per critical field. Use **plain language**, not the YAML field names:
+
+| Bug-report field | Prompt to user |
+|---|---|
+| `description` | "What went wrong? One sentence is fine." |
+| `steps` | "How can I reproduce it? Walk me through step by step." |
+| `expected` | "What did you expect to happen?" |
+| `version` | "Which OD version are you running? (About menu, or `od --version`)" |
+| `platform` | dropdown: macOS (Apple Silicon) / macOS (Intel) / Windows / Linux / Other |
+| `logs` | "Any error logs you can paste? Skip if you don't have them." |
+| `screenshots` | "Path to a screenshot? Skip if you don't have one." |
+
+Translate every prompt above into the user's chat language at runtime.
+
+**3d.3** Auto-collect what we can (these don't need to ask the user):
+- OS family from `uname`
+- Node version from `node -v` if relevant
+
+**3d.4** Dedupe: extract 3–5 keywords from the description, run:
+
+```bash
+gh search issues "<keywords>" --repo "$TARGET_REPO" --state open --limit 5 --json number,title,url
+```
+
+If matches exist, present them to the user via `AskUserQuestion` (translate to user's language): "These existing issues look related. Do you want to: (a) comment on an existing one, (b) open a new issue anyway, (c) cancel?"
+
+**3d.5** If proceeding with new issue, render `templates/ISSUE-BODY-bug.md` and submit:
+
+```bash
+bash "$SKILL_DIR/scripts/create-issue.sh" \
+  --title "$TITLE" \
+  --body-file "$WORKDIR_OR_TMP/.od-contrib/ISSUE-BODY.md" \
+  --dedupe-keywords "<keywords>"
+```
+
+**3d.6** Print the issue URL on its own line. **Do not** push branches or open PRs from this branch.
+
+---
+
+## Step 7 — Preview + confirm (shared, PR branches only)
+
+Show the user a clean summary:
+
+```text
+About to commit:
+  Branch:  od-contrib/<type>/<slug>-<date>
+  Files:
+    + skills/foo/SKILL.md            (1.2 KB)
+    + skills/foo/preview.png         (54 KB)
+  Push to:  <fork or upstream>
+  Open PR:  nexu-io/open-design:main ← <fork>:<branch>
+```
+
+Then `git -C "$WORKDIR" diff --stat` and a `head -40` of the rendered PR body for visual sanity.
+
+Required `AskUserQuestion` confirmation (translate to user's language): **"Push this PR?"** with three options:
+- **Ship it** — proceed to Step 8
+- **Let me revise** — return to the relevant Step 3 sub-step
+- **Cancel** — leave the workspace on disk, tell the user the path so they can return later, exit
+
+Never push without an explicit "Ship it".
+
+## Step 8 — Push & open PR
+
+```bash
+bash "$SKILL_DIR/scripts/create-pr.sh" \
+  --workdir "$WORKDIR" \
+  --type "<skill|design-system|i18n|docs>" \
+  --title "<PR title from references/newcomer-tone.md>" \
+  --body-file "$WORKDIR/.od-contrib/PR-BODY.md"
+```
+
+Print the PR URL on its own line. Done.
+
+---
+
+## Safety rails (mandatory)
+
+- Never push to `main` / `master` / `develop`. The push scripts refuse.
+- Never `--force` push. Just don't.
+- All workspace activity stays under `$OD_WORK_ROOT` (default `$HOME/od-contrib-work`). `od::assert_in_workroot` enforces this.
+- Bug-report path **always** runs the dedupe search before `gh issue create`.
+- Honor user memory: skip GitHub user `xxiaoxiong` from any contributor lookup ([[feedback_no_outreach_xxiaoxiong]]).
+
+## When NOT to use this skill
+
+- The user wants to fix a daemon / web bug or add a feature with code changes → use `auto-github-contributor` instead (it has the TDD loop). This skill deliberately doesn't run lint/typecheck/tests because content paths don't need them.
+- The user wants to *generate* a Skill / Design System from scratch → that's Open Design itself. Run OD first, get an artifact, then come back here to ship it.

+
+Section ordering and exact titles vary — the validator only checks **structural overlap with reference systems**, not exact heading text. ≥30% overlap with the union of headings from existing systems is enough to pass.
+
+## What the validator actually enforces
+
+1. File is non-empty and has at least one H1.
+2. ≥30% heading overlap with reference DESIGN.md files (when references are passed in).
+3. No `../` relative paths that would resolve outside `design-systems/<brand>/`.
+
+That's deliberately loose — DESIGN.md is a creative brief, not a schema.
+
+## Don'ts
+
+- Don't reference assets outside the brand folder.
+- Don't paste binary fonts; use a CSS `@font-face` reference and let OD resolve at runtime.
+- Don't use real customer logos / proprietary brand assets you don't have rights to (the validator won't catch this — it's a maintainer-review concern).

+# Newcomer tone — voice rules for PR / issue text
+
+Per user feedback ([[feedback_outreach_minimal]]), keep it minimal. The PR body is the **only** place we get to shape the maintainer's first impression of this contributor — make it warm, brief, and useful.
+
+## Hard rules
+
+1. **Always end the PR body with two things:**
+   - "👋 This is my first OD contribution." (or a similar one-line warmth)
+   - The OD Discord invite: <https://discord.gg/qhbcCH8Am4> (read from `OD_DISCORD_INVITE` env, never hardcode)
+2. **Never claim more than the PR actually does.** A typo fix is a typo fix — don't dress it up as "improving documentation quality" or list 5 fake checkboxes.
+3. **Plain language only.** No "ergonomic", "DX", "stakeholder", "stack rank". Talk like a friendly user, not a startup blog.
+4. **No emojis except the opening 👋 and one optional 🎨 / 🌍 / 📝 / 🐛 in the title or first line.** OD is design-loving but the maintainers read a *lot* of PRs.
+
+## Soft rules
+
+- Lead with **what changed**, not why or how. Maintainers can read the diff for the how.
+- "Why" gets at most 2–3 sentences. If it needs more, the work is too big for this skill — open an issue instead.
+- One screenshot if the change is visible. Zero is fine.
+- The "checklist" should reflect what the validator actually checked, not a generic ceremonial list.
+
+## Anti-patterns (do not do these)
+
+- **Don't** write an "ask" section. Don't say "please review when you have time" — the PR is the ask.
+- **Don't** invite the maintainer to call / DM you. Discord is the channel.
+- **Don't** apologize. ("Sorry if this isn't right" — the maintainer will tell you if it isn't.)
+- **Don't** include a "TL;DR" — if the summary needs a TL;DR, the summary is too long.
+
+## Title conventions (for `git commit` and `gh pr create --title`)
+
+| Type | Format | Example |
+|---|---|---|
+| Skill | `Add Skill: <name>` | `Add Skill: invoice-template` |
+| Design System | `Add Design System: <brand>` | `Add Design System: notion` |
+| i18n | `Translate <doc> to <Lang>` | `Translate QUICKSTART to Spanish` |
+| i18n (refresh) | `Update <Lang> translation of <doc>` | `Update zh-CN translation of README` |
+| Docs typo | `Fix typo in <file>` | `Fix typo in README.md` |
+| Docs other | `<verb> <noun> in <where>` | `Clarify daemon setup in QUICKSTART` |
+| Bug (issue title) | `<observed> on <surface>` | `Preview iframe is blank on Safari 17` |
+
+## When to ask before writing
+
+If the user wants to ship something whose tone is unusual (a manifesto blog post, a contentious refactor, naming a brand after a real company without rights), pause and ask the user. Better to skip the PR than ship something the maintainer will close politely.

+# OD repo map — what goes where
+
+Mirrors `nexu-io/open-design` `CONTRIBUTING.md` so the skill doesn't need to re-fetch it on every run. **If this drifts from upstream CONTRIBUTING.md, upstream wins** — re-read the live file when in doubt.
+
+## Three high-leverage contribution surfaces (per OD's CONTRIBUTING.md)
+
+| If you want to… | You're really adding | Where it lives | Ship size |
+|---|---|---|---|
+| Make OD render a new kind of artifact | a **Skill** | `skills/<your-skill>/` | one folder, ~2 files |
+| Make OD speak a new brand's visual language | a **Design System** | `design-systems/<brand>/DESIGN.md` | one Markdown file |
+| Hook up a new coding-agent CLI | an **Agent adapter** | `apps/daemon/src/agents.ts` | ~10 lines (code — out of scope for this skill) |
+| Improve docs, port a section to fr / de / zh-CN, fix typos | docs | `README.md`, `README.fr.md`, `README.de.md`, `README.zh-CN.md`, `docs/`, `QUICKSTART.md` | one PR |
+
+## Localized doc files we know about
+
+| Doc family | English source | Translations seen on disk (as of plan time) |
+|---|---|---|
+| README | `README.md` | ar, de, es, fr, ja-JP, ko, pt-BR, ru, tr, uk, zh-CN, zh-TW |
+| QUICKSTART | `QUICKSTART.md` | de, fr, ja-JP, pt-BR, zh-CN, zh-TW |
+| CONTRIBUTING | `CONTRIBUTING.md` | de, fr, ja-JP, pt-BR, zh-CN |
+| MAINTAINERS | `MAINTAINERS.md` | de, fr, ja-JP, pt-BR, zh-CN |
+
+The skill `discover-i18n-gaps.sh` does NOT trust this table — it scans the workspace at runtime. Use this list only when you need to seed an `AskUserQuestion` card without a workspace.
+
+## Issue templates
+
+- `bug-report.yml` — required fields: description, steps to reproduce, expected, version, platform.
+- `feature-request.yml` — out of scope for this skill (feature requests should come from product, not auto-routed.)
+- `preview-v0.8.0-feedback.yml` — branch-specific.
+
+## Out-of-scope surfaces (don't touch from this skill)
+
+- `apps/daemon/src/` — daemon code. Requires real review.
+- `apps/web/src/` — web app code. Requires real review.
+- `packages/`, `plugins/`, `tools/` — internal libs.
+- `e2e/` — Playwright-driven; non-trivial to author.
+
+If a user asks to contribute to those surfaces, suggest the original `auto-github-contributor` skill (TDD pipeline) instead.

+# What an OD skill folder looks like
+
+Reference for the `od-contribute` skill's `validate-skill-submission.sh` step and for guiding a user through assembling a Skill submission.
+
+> **Authoritative source**: read 1–2 existing folders under `skills/` in `nexu-io/open-design` at runtime — conventions evolve faster than this doc.
+
+## Minimum viable skill
+
+```
+skills/<your-skill>/
+└── SKILL.md          # required, must have YAML frontmatter
+```
+
+That's it. Many of the simplest skills in OD are exactly that: one Markdown file in one folder.
+
+## Frontmatter — what `validate-skill-submission.sh` requires
+
+```yaml
+---
+name: <kebab-case-slug>           # required; usually matches the folder name
+description: |                    # required; one paragraph; what the skill does in user terms
+  Generate and iterate ad creative including headlines, descriptions, and primary text.
+triggers:                         # optional but strongly recommended
+  - "ad creative"
+  - "ad headline"
+od:                               # optional; OD-specific metadata
+  mode: design-system             # or other modes; check existing skills
+  category: <category-slug>
+  upstream: "https://github.com/..."  # if the skill was lifted from somewhere
+---
+```
+
+**Required by validator**: `name`, `description`. Everything else is convention.
+
+## Body conventions (after the frontmatter)
+
+Looking at existing skills, the typical body has:
+
+1. `# <skill-name>` H1.
+2. A one-line "what it does" sentence.
+3. Optional `## Source` block when adapted from upstream (with attribution).
+4. `## How to use` with one or two example prompts the user might type.
+
+## When a skill folder needs more than `SKILL.md`
+
+- **Reference assets** — long prompt fragments, example outputs, image references — go alongside `SKILL.md` in the same folder, referenced via relative paths in `SKILL.md`.
+- **Subfolders** are fine: the validator only requires that every relative reference inside `SKILL.md` resolves and that no path escapes the skill folder.
+
+## Don'ts
+
+- Don't put runtime code in here. Skills are *content* — Markdown + maybe assets. Code adapters live in `apps/daemon/src/`.
+- Don't reference files outside `skills/<your-skill>/` — that breaks portability.
+- Don't put binaries you don't need (the lighter the folder, the easier the review).

 ## Validation strategy
 
 - After package, workspace, or command-entry changes, run `pnpm install` so workspace links and generated dist entries stay fresh.
+- For agent-stream / parser changes (`apps/daemon/src/claude-stream.ts`, `json-event-stream.ts`, `qoder-stream.ts`, etc.), replay a recorded session through the mock CLIs in `mocks/` to verify event shapes round-trip without burning provider budget. PATH-overlay activation: `export PATH="$PWD/mocks/bin:$PATH" OD_MOCKS_TRACE=<8-char-id> OD_MOCKS_NO_DELAY=1`. See `mocks/README.md` for the trace catalog and selection knobs.
 - Treat every `pnpm-lock.yaml` change as requiring a Nix pnpm deps hash refresh check. `nix/pnpm-deps.nix` is a generated lock artifact; use `pnpm nix:update-hash` only when intentionally maintaining Nix packaging, then re-run `nix flake check --print-build-logs --keep-going`. Contributors without Nix can rely on the PR `Validate workspace` gate, which now uploads or auto-applies the generated hash-only fix when possible.
 - Before marking regular work ready, run at least `pnpm guard` and `pnpm typecheck`, plus the package-scoped tests/builds that match the files changed. Do not use or add root `pnpm test`/`pnpm build` aliases.
 - For local web runtime loops, prefer `pnpm tools-dev run web --daemon-port <port> --web-port <port>`.

No re-prompting, no "ask the model to re-create what we just had". ([`apps/daemon/src/server.ts`](apps/daemon/src/server.ts) — `/api/import/claude-design`)
 - **Multi-provider BYOK proxy.** `POST /api/proxy/{anthropic,openai,azure,google,ollama,senseaudio}/stream` takes `{ baseUrl, apiKey, model, messages }`, builds the provider-specific upstream request, normalizes SSE chunks into `delta/end/error`, and allows loopback local LLM providers while rejecting non-loopback private, link-local, CGNAT, multicast, reserved, and redirect targets to head off SSRF. OpenAI-compatible covers OpenAI, Azure AI Foundry `/openai/v1`, DeepSeek, Groq, MiMo, OpenRouter, Ollama, LM Studio, and self-hosted vLLM; Azure OpenAI adds deployment URL + `api-version`; Google uses Gemini `:streamGenerateContent`.

 - **Tab persistence.** Every project remembers its open files and active tab in the `tabs` table. Reopen the project tomorrow and the workspace looks exactly the way you left it.
 - **Artifact lint API.** `POST /api/artifacts/lint` runs structural checks on a generated artifact (broken `<artifact>` framing, missing required side files, stale palette tokens) and returns findings the agent can read back into its next turn. The five-dim self-critique uses this to ground its score in real evidence, not vibes.
 - **Sidecar protocol + desktop automation.** Daemon, web, and desktop processes carry typed five-field stamps (`app · mode · namespace · ipc · source`) and expose a JSON-RPC IPC channel at `/tmp/open-design/ipc/<namespace>/<app>.sock`. `tools-dev inspect desktop status \| eval \| screenshot` drives that channel, so headless E2E works against a real Electron shell without bespoke harnesses ([`packages/sidecar-proto/`](packages/sidecar-proto/), [`apps/desktop/src/main/`](apps/desktop/src/main/)).

+// Regex matching fabricated role-marker lines injected by the model into
+// its own output. Anchored to start-of-line via (?:^|\n) so we don't
+// false-positive on user prose like "here is the ## user content".
+//
+// Scope (deliberately narrow): Markdown-style `## user` / `## assistant`
+// / `## assist` / `## system` only — these are the patterns the chat
+// host actually parses as turn boundaries (see `buildDaemonTranscript`
+// in apps/web/src/providers/daemon.ts). Chat-style markers like
+// `User:` / `Assistant:` / `Human:` / `AI:` are intentionally NOT
+// included, because:
+//   (1) The host never parses them as turn boundaries; a model emitting
+//       them does NOT cause the original #3247 security failure mode.
+//   (2) They collide with legitimate output far more often than the
+//       Markdown family (e.g., "User: bob@example.com", form labels,
+//       JSDoc lines). With kill-on-detection wired in server.ts
+//       (`abortForRoleMarker`), a false positive aborts the whole run
+//       — a much more expensive failure than a stray unflagged
+//       `User:` line in the chat scrollback.
+// If a host frontend ever starts parsing chat-style markers as
+// boundaries, narrow the additions to that frontend's specific
+// path rather than the shared regex.
+//
+// Three deliberate refinements vs. a naive `## role` match:
+//
+// 1. CASE-SENSITIVE. The chat host's turn-boundary delimiter is
+//    lowercase (`## user` / `## assistant` / `## system` — see
+//    `buildDaemonTranscript` in apps/web/src/providers/daemon.ts), and
+//    the `## CRITICAL` system-prompt block forbids only the lowercase
+//    forms. Title-Case Markdown headings like `## User Guide`,
+//    `## System Architecture`, `## Assistant settings` are LEGITIMATE
+//    content (LLMs emit these constantly in technical writing) and
+//    must not contaminate. Matching with `/i` would deterministically
+//    abort any run that produced such a heading — exactly the
+//    "false positive aborts the whole run" cost the docblock cites
+//    as the reason to keep the regex narrow.
+//    (See PR #3303 review r3324151877.)
+//
+// 2. POSITIVE LOOKAHEAD `(?=[^a-z])`. Without it, `## userland`,
+//    `## userspace`, `## users guide`, `## systemd`, `## assistance`
+//    all match via prefix in the alternation. The positive lookahead
+//    requires the character after the role keyword to exist AND to NOT
+//    be a lowercase letter:
+//      - `## user\n…`     → match (newline is not lowercase)
+//      - `## assistantR…` → match (R is uppercase; the glued-form
+//                           attack pattern still gets caught)
+//      - `## assistant.`  → match (. is not a letter)
+//      - `## users guide` → no match (s is lowercase letter)
+//      - `## userland`    → no match (l is lowercase letter)
+//    Why POSITIVE `[^a-z]` rather than NEGATIVE `(?![a-z])`: the
+//    negative form is satisfied at end-of-string, which in a streaming
+//    context means "we have just received `## user` but don't know
+//    what comes next yet". A negative lookahead would fire prematurely
+//    if the rest of the role-keyword landed in a later chunk (e.g.
+//    the model emits `## user` then `land` arrives). The positive
+//    form requires an actual non-lowercase character to be present,
+//    so detection waits one more chunk in that edge case — a
+//    one-character latency traded for correctness.
+//
+// 3. `[ \t]` instead of `\s` for inner whitespace. `\s` matches
+//    newlines, which would let oddities like `##\nuser` match across
+//    lines. Markdown role markers are always single-line by
+//    convention; restricting to space/tab tightens the match without
+//    losing any real attack pattern.
+//
+// Alternation order: `assistant` is listed before `assist` so a
+// fully-spelled `## assistant` consumes 9 chars (not 6) and the
+// `(?![a-z])` check is applied at position 9 (after the full word)
+// rather than position 6. Truncated forms (`## assist\n` from a
+// stream cut mid-emission) still match via the `assist` branch.

+// AFTER the role keyword, which by definition can't be present when
+// the chunk boundary fell exactly between the role keyword and its
+// next byte. If one of these matches, the role keyword IS at the end
+// of the current buffer; we withhold it and revisit on the next

+//       no longer matches the role keyword → withheld bytes are
+//       confirmed safe and emitted alongside the new chunk.
+//   (3) The role keyword is part of a longer word that itself is a
+//       role keyword (only `user` ⊂ `users`, etc. — none extend to
