 **Never give up on the right solution.**
 
+## What Hermes Is
+
+Hermes is a personal AI agent that runs the same agent core across a CLI, a
+messaging gateway (Telegram, Discord, Slack, and ~20 other platforms), a TUI,
+and an Electron desktop app. It learns across sessions (memory + skills),
+delegates to subagents, runs scheduled jobs, and drives a real terminal and
+browser. It is extended primarily through **plugins and skills**, not by
+growing the core.
+
+Two properties shape almost every design decision and are the lens for
+reviewing any change:
+
+- **Per-conversation prompt caching is sacred.** A long-lived conversation
+  reuses a cached prefix every turn. Anything that mutates past context,
+  swaps toolsets, or rebuilds the system prompt mid-conversation invalidates
+  that cache and multiplies the user's cost. We do not do it (the one
+  exception is context compression).
+- **The core is a narrow waist; capability lives at the edges.** Every model
+  tool we add is sent on every API call, so the bar for a new *core* tool is
+  high. Most new capability should arrive as a CLI command + skill, a
+  service-gated tool, or a plugin — not as core surface.
+
+## Contribution Rubric — What We Want / What We Don't
+
+This is the project's intent layer. Use it two ways:
+
+1. **For humans and for your own work** — what gets merged and what gets
+   rejected, so a contribution aims at the target.
+2. **For automated review (the triage sweeper)** — guidance on when a PR is
+   safe to close on the three allowed reasons (`implemented_on_main`,
+   `cannot_reproduce`, `incoherent`) and, just as important, **when NOT to
+   close** one. Taste-based "we don't want this / out of scope" closes are NOT
+   an automated decision — those stay with a human maintainer. The sweeper's
+   job here is to recognize design intent and *avoid wrongly closing a
+   legitimate contribution*, not to make the won't-implement call itself.
+
+Read the balance right: Hermes ships a **lot** — most merges are bug fixes to
+real reported behavior, and the product surface (platforms, channels,
+providers, models, desktop/TUI features) expands aggressively and on purpose.
+The restraint below is aimed squarely at the **core agent + the model tool
+schema**, the one place where every addition is paid for on every API call.
+"Smallest footprint" governs *how a capability is wired into the core*, NOT
+whether the product is allowed to grow. We are expansive at the edges and
+conservative at the waist.
+
+### What we want
+
+- **Fix real bugs, well.** The bulk of what lands is `fix(...)` against an
+  actual reported symptom. A good fix reproduces the symptom on current
+  `main`, points to the exact line where it manifests, and fixes the whole bug
+  class — sibling call paths included — not just the one site the reporter hit.
+- **Expand reach at the edges.** New platform adapters, channels, providers,
+  models, and desktop/TUI/dashboard features are welcome and land routinely,
+  including large ones (a new messaging channel, a session-cap feature, a
+  Windows PTY bridge). Breadth in the product is a goal, not a footprint
+  concern — as long as it integrates with the existing setup/config UX
+  (`hermes tools`, `hermes setup`, auto-install) rather than bolting on a raw
+  env var.
+- **Refactor god-files into clean modules.** Extracting a multi-thousand-line
+  cluster out of `cli.py` / `run_agent.py` / `gateway/run.py` into a focused
+  mixin or module is wanted work, even when the diff is huge and mechanical
+  (large `+N/-N` refactors merge regularly). The "every line traces to the
+  request" test applies to *feature* PRs; a declared refactor's request IS the
+  extraction.
+- **Keep the core narrow.** New *model tools* are the expensive exception —
+  every tool ships on every API call. Prefer, in order: extend existing code →
+  CLI command + skill → service-gated tool (`check_fn`) → plugin → MCP server
+  in the catalog → new core tool (last resort). See "The Footprint Ladder."
+- **Extend, don't duplicate.** Before adding a module/manager/hook, check
+  whether existing infrastructure already covers the use case. When several PRs
+  integrate the same *category*, design one shared interface instead of merging
+  them one at a time (see the ABC + orchestrator note under the Footprint
+  Ladder).
+- **Behavior contracts over snapshots.** Tests should assert how two pieces of
+  data must relate (invariants), not freeze a current value (model lists,
+  config version literals, enumeration counts). See "Don't write
+  change-detector tests."
+- **E2E validation, not just green unit mocks.** For anything touching
+  resolution chains, config propagation, security boundaries, remote
+  backends, or file/network I/O, exercise the real path with real imports
+  against a temp `HERMES_HOME`. Mocks hide integration bugs.
+- **Cache-, alternation-, and invariant-safe.** Preserve prompt caching, strict
+  message role alternation (never two same-role messages in a row; never a
+  synthetic user message injected mid-loop), and a system prompt that is
+  byte-stable for the life of a conversation.
+- **Contributor credit preserved.** Salvage external work by cherry-picking
+  (rebase-merge) so authorship survives in git history; don't reimplement from
+  scratch when you can build on top.
+
+### What we don't want (rejected even when well-built)
+
+- **Speculative infrastructure.** Hooks, callbacks, or extension points with no
+  concrete consumer. Adding a hook is easy; removing one after plugins depend
+  on it is hard. A hook is NOT speculative if a contributor has a real, stated
+  use case — even if the consumer ships separately.
+- **New `HERMES_*` env vars for non-secret config.** `.env` is for secrets
+  only (API keys, tokens, passwords). All behavioral settings — timeouts,
+  thresholds, feature flags, display prefs — go in `config.yaml`. Bridge to an
+  internal env var if the mechanism needs one, but user-facing docs point to
+  `config.yaml`. Reject PRs that tell users to "set X in your .env" unless X
+  is a credential.
+- **A new core tool when terminal + file already do the job, or when a skill
+  would.** If the only barrier is file visibility on a remote backend, fix the
+  mount, not the toolset.
+- **Lazy-reading escape hatches on instructional tools.** No `offset`/`limit`
+  pagination on tools that load content the agent must read fully (skills,
+  prompts, playbooks). Models will read page 1 and skip the rest.
+- **"Fixes" that destroy the feature they secure.** A mitigation that kills the
+  feature's purpose is the wrong mitigation. Read the original commit's intent
+  (`git log -p -S`) before restricting behavior; find a fix that preserves the
+  feature.
+- **Outbound telemetry / usage attribution without opt-in gating.** No new
+  analytics, third-party identifier tagging, or attribution tags until a
+  generic user-facing opt-in (config gate + setup prompt + `hermes tools`
+  toggle) exists. Park behind a label, do not merge.
+- **Change-detector tests, cache-breaking mid-conversation, dead code wired in
+  without E2E proof, and plugins that touch core files.** Plugins live in their
+  own directory and work within the ABCs/hooks we provide; if a plugin needs
+  more, widen the generic plugin surface, don't special-case it in core.
+
+### Before you call it a bug — verify the premise (and when NOT to close)
+
+The most common reason a well-written PR gets closed is not code quality — it
+is that the change is built on a **wrong premise**, or it treats an
+**intentional design as a gap**. These patterns cut both ways: they tell a
+human reviewer what to scrutinize, and they tell the automated sweeper when a
+PR is NOT safe to close as `implemented_on_main` / `cannot_reproduce` (when in
+doubt, leave it open for a human). They are distilled from real closes.
+
+- **"Intentional design, not a gap."** A limitation that looks like an
+  oversight is often deliberate. Before "fixing" a missing link or a
+  restriction, ask whether the isolation IS the design. Example: profiles are
+  independent islands on purpose — a PR adding live config inheritance from the
+  default profile was closed because coupling profiles together is exactly what
+  the design prevents (the copy-at-creation `--clone` path already covers the
+  legitimate "start from my default" case). Read the original commit's intent
+  (`git log -p -S "<symbol>"`) before assuming something is unfinished.
+- **"The premise doesn't hold against how X actually works."** A PR's
+  justification frequently rests on a wrong mental model of an existing
+  mechanism. Trace the real code/runtime before accepting the rationale. Two
+  real closes: a rate-limit "re-probe during cooldown" PR (the breaker only
+  trips on a *confirmed-empty* account bucket, so re-probing just hammers a
+  bucket we've already proven empty); a usage-accumulation fix whose new branch
+  **never executes at runtime** because an earlier guard already popped the
+  state it depended on. If you can't point to the exact line where the bug
+  manifests AND show the fix changes that line's behavior, you haven't verified
+  the premise.
+- **"This fix was wrong — the absence/omission was deliberate."** Adding the
+  obvious-looking missing piece can break things the omission was protecting.
+  Example: restoring "missing" `__init__.py` files made a test tree importable
+  as a dotted package that shadowed the real plugin, deleting its `register()`
+  at import time. The absence was load-bearing.
+- **"Overreached / resurrected an approach we'd moved past."** Scope creep that
+  supersedes an agreed-on base, or revives a direction the maintainers
+  deliberately closed, gets rejected even when the code works. Keep the change
+  to the narrow piece that was actually agreed; offer the rest as a focused
+  follow-up.
+
+The throughline: **verify the claim AND the intent against the codebase before
+writing or merging a fix.** A confirmed reproduction on current `main` plus a
+line-level account of where the fix acts beats a plausible-sounding rationale
+every time. When in doubt about intent, it is cheaper to ask than to ship a
+fix that fights the design.
+
+### The Footprint Ladder (new capability decision)
+
+Each rung adds more permanent surface than the one above. Choose the highest
+(least-footprint) rung that correctly solves the problem:
+
+1. **Extend existing code** — the capability is a variation of something that
+   already exists. Zero new surface.
+2. **CLI command + skill** — manages config/state/infra expressible as shell
+   commands. The agent runs `hermes <subcommand>` guided by a skill. Zero
+   model-tool footprint. Default choice for subscriptions, scheduled tasks,
+   service setup. Examples: `hermes webhook`, `hermes cron`, `hermes tools`.
+3. **Service-gated tool (`check_fn`)** — needs structured params/returns AND
+   only appears when a prerequisite is configured. Zero footprint otherwise.
+   Examples: Home Assistant tools (gated on token), memory-provider tools.
+4. **Plugin** — third-party/niche/user-specific capability that doesn't ship in
+   core. Lives in `~/.hermes/plugins/` or a pip package, discovered at runtime.
+5. **MCP server (in the catalog)** — if the capability genuinely needs to be a
+   tool (structured I/O the agent invokes) but isn't core-fundamental, prefer
+   building it as an MCP server and adding it to the MCP catalog over growing
+   the core toolset. The agent connects to it through the built-in MCP client;
+   zero permanent core-schema footprint, and it's reusable by any MCP host.
+6. **New core tool** — only when the capability is fundamental, broadly useful
+   to nearly every user, and unreachable via terminal + file (or an MCP server).
+   Examples of correct core tools: terminal, read_file, web_search,
+   browser_navigate.
+
+When 3+ open PRs try to integrate the same *category* of thing (memory
+backends, providers, notifiers), don't merge them one at a time — design an
+ABC + orchestrator, wrap the existing built-in as the first provider, and turn
+the competing PRs into plugins against that interface.

 **The self-improving AI agent built by [Nous Research](https://nousresearch.com).** It's the only agent with a built-in learning loop — it creates skills from experience, improves them during use, nudges itself to persist knowledge, searches its own past conversations, and builds a deepening model of who you are across sessions. Run it on a $5 VPS, a GPU cluster, or serverless infrastructure that costs nearly nothing when idle. It's not tied to your laptop — talk to it from Telegram while it works on a cloud VM.

+### ونڈوز (نیٹو، پاور شیل)
+
+> **توجہ فرمائیں:** مقامی ونڈوز (Native Windows) پر ہرمیس بغیر WSL کے چلتا ہے — CLI، گیٹ وے، TUI، اور ٹولز سب مقامی طور پر کام کرتے ہیں۔ اگر آپ WSL2 استعمال کرنا پسند کرتے ہیں، تو اوپر دی گئی لینکس/میک او ایس کی کمانڈ وہاں بھی کام کرے گی۔ کوئی مسئلہ نظر آیا؟ براہ کرم [مسائل (issues) درج کریں](https://github.com/NousResearch/hermes-agent/issues)۔
+
+اسے پاور شیل (PowerShell) میں چلائیں:
+
+<div dir="ltr">
+
+```powershell
+iex (irm https://hermes-agent.nousresearch.com/install.ps1)
+```

+</div>
+
+انسٹالر سب کچھ خود سنبھالتا ہے: uv، Python 3.11، Node.js، ripgrep، ffmpeg، **اور ایک پورٹ ایبل (portable) گٹ بیش (Git Bash)** (یعنی MinGit، جو `%LOCALAPPDATA%\hermes\git` میں ان پیک ہوتا ہے — اس کے لیے ایڈمن کی اجازت درکار نہیں، اور یہ سسٹم کے کسی بھی گٹ انسٹال سے بالکل الگ ہے)۔ ہرمیس اس بنڈل شدہ گٹ بیش کو شیل کمانڈز چلانے کے لیے استعمال کرتا ہے۔
+
+اگر آپ کے پاس پہلے سے گٹ (Git) انسٹال ہے، تو انسٹالر اسے شناخت کر لیتا ہے اور اسے ہی استعمال کرتا ہے۔ بصورت دیگر آپ کو صرف ~45MB کے MinGit ڈاؤنلوڈ کی ضرورت ہوگی — یہ آپ کے سسٹم کے گٹ پر کوئی اثر نہیں ڈالے گا۔
+
+> **اینڈرائیڈ (Android) / ٹرمکس (Termux):** ٹیسٹ کیا گیا مینوئل طریقہ [Termux گائیڈ](https://hermes-agent.nousresearch.com/docs/getting-started/termux) میں موجود ہے۔ ٹرمکس پر ہرمیس ایک مخصوص `.[termux]` ایکسٹرا انسٹال کرتا ہے کیونکہ مکمل `.[all]` ایکسٹرا میں ایسی وائس ڈیپینڈینسیز شامل ہیں جو اینڈرائیڈ کے ساتھ مطابقت نہیں رکھتیں۔
+>
+> **ونڈوز (Windows):** مقامی ونڈوز کی مکمل سپورٹ موجود ہے — اوپر دی گئی پاور شیل کی کمانڈ سب کچھ انسٹال کر دیتی ہے۔ اگر آپ WSL2 استعمال کرنا چاہتے ہیں، تو لینکس کی کمانڈ وہاں کام کرتی ہے۔ مقامی ونڈوز میں انسٹالیشن `%LOCALAPPDATA%\hermes` میں ہوتی ہے؛ جبکہ WSL2 میں لینکس کی طرح `~/.hermes` میں ہوتی ہے۔ ہرمیس کا وہ واحد فیچر جسے فی الحال خاص طور پر WSL2 کی ضرورت ہے وہ براؤزر پر مبنی ڈیش بورڈ چیٹ پین ہے (یہ POSIX PTY استعمال کرتا ہے — کلاسک CLI اور گیٹ وے دونوں مقامی طور پر چلتے ہیں)۔

+## API-کیز اکٹھی کرنے سے بچیں — Nous Portal
+
+ہرمیس آپ کے پسندیدہ پرووائیڈر کے ساتھ کام کرتا ہے — یہ چیز تبدیل نہیں ہو رہی۔ لیکن اگر آپ ماڈل، ویب سرچ، امیج جنریشن، TTS، اور کلاؤڈ براؤزر کے لیے پانچ الگ الگ API کیز جمع نہیں کرنا چاہتے، تو **[Nous Portal](https://portal.nousresearch.com)** ان سب کو ایک ہی سبسکرپشن کے تحت کور کرتا ہے:
+
+- **300+ ماڈلز** — ان میں سے کوئی بھی ماڈل `/model <name>` کے ذریعے منتخب کریں
+- **ٹول گیٹ وے (Tool Gateway)** — ویب سرچ (Firecrawl)، امیج جنریشن (FAL)، ٹیکسٹ ٹو سپیچ (OpenAI)، کلاؤڈ براؤزر (Browser Use)، یہ سب آپ کی سبسکرپشن کے ذریعے چلتے ہیں۔ کسی اضافی اکاؤنٹ کی ضرورت نہیں۔
+
+نئی انسٹالیشن کے بعد بس ایک کمانڈ کی ضرورت ہے:
+
+<div dir="ltr">
+
+```bash
+hermes setup --portal
+```
+
+</div>
+
+یہ آپ کو OAuth کے ذریعے لاگ ان کرواتا ہے، Nous کو آپ کا پرووائیڈر مقرر کرتا ہے، اور ٹول گیٹ وے کو آن کر دیتا ہے۔ `hermes portal info` کمانڈ استعمال کر کے آپ کسی بھی وقت چیک کر سکتے ہیں کہ کون کون سی سروسز منسلک ہیں۔ مکمل تفصیلات [Tool Gateway دستاویزات کے صفحے](https://hermes-agent.nousresearch.com/docs/user-guide/features/tool-gateway) پر موجود ہیں۔
+
+آپ اب بھی کسی بھی ٹول کے لیے اپنی مرضی کی API کیز استعمال کر سکتے ہیں — گیٹ وے ہر سروس کے لیے الگ الگ کام کرتا ہے، ایسا نہیں کہ یا تو سب کچھ استعمال کریں یا کچھ بھی نہیں۔

+## CLI بمقابلہ میسجنگ فوری حوالہ
+
+ہرمیس کے دو بنیادی انٹر فیس ہیں: آپ ٹرمینل UI کو `hermes` کے ساتھ شروع کریں، یا گیٹ وے چلا کر اس کے ساتھ ٹیلی گرام، ڈسکارڈ، سلیک، واٹس ایپ، سگنل، یا ای میل کے ذریعے بات کریں۔ جب آپ کسی بات چیت میں ہوتے ہیں، تو بہت سی سلیش (slash) کمانڈز دونوں انٹرفیسز میں ایک جیسی ہوتی ہیں۔

+## OpenClaw سے منتقلی
+
+اگر آپ OpenClaw سے منتقل ہو رہے ہیں، تو ہرمیس آپ کی سیٹنگز، یادیں (memories)، مہارتیں (skills)، اور API کیز کو خود بخود امپورٹ کر سکتا ہے۔
+
+**پہلی بار سیٹ اپ کے دوران:** سیٹ اپ وزرڈ (`hermes setup`) خود بخود `~/.openclaw` کو پہچان لیتا ہے اور کنفیگریشن شروع ہونے سے پہلے مائیگریٹ (migrate) کرنے کا آپشن دیتا ہے۔
+
+**انسٹالیشن کے بعد کسی بھی وقت:**
+
+<div dir="ltr">
+
+```bash
+hermes claw migrate              # انٹرایکٹو مائیگریشن (مکمل پری سیٹ)
+hermes claw migrate --dry-run    # جائزہ لیں کہ کیا کیا مائیگریٹ ہوگا
+hermes claw migrate --preset user-data   # حساس معلومات (secrets) کے بغیر مائیگریٹ کریں
+hermes claw migrate --overwrite  # موجودہ متصادم فائلوں کو اوور رائٹ کریں
+```
+
+</div>
+
+جو چیزیں امپورٹ ہوتی ہیں:
+
+- **SOUL.md** — پرسونا (persona) فائل
+- **میموریز (Memories)** — MEMORY.md اور USER.md کی اندراجات
+- **مہارتیں (Skills)** — صارف کی بنائی گئی مہارتیں → `~/.hermes/skills/openclaw-imports/`
+- **کمانڈ الاؤ لسٹ (allowlist)** — منظوری کے پیٹرنز (approval patterns)
+- **میسجنگ سیٹنگز** — پلیٹ فارم کنفیگریشنز، اجازت یافتہ صارفین، ورکنگ ڈائریکٹری
+- **API کیز** — الاؤ لسٹ شدہ حساس معلومات (ٹیلی گرام، OpenRouter، OpenAI، Anthropic، ElevenLabs)
+- **TTS اثاثے** — ورک اسپیس کی آڈیو فائلیں
+- **ورک اسپیس کی ہدایات** — AGENTS.md (`--workspace-target` کے ساتھ)
+
+تمام آپشنز دیکھنے کے لیے `hermes claw migrate --help` استعمال کریں، یا انٹرایکٹو ایجنٹ کی مدد سے مائیگریٹ کرنے کے لیے `openclaw-migration` سکل کا استعمال کریں (جس میں ڈرائی رن (dry-run) پریویوز شامل ہیں)۔

+"""Per-turn setup for ``run_conversation`` (the turn prologue).
+
+``run_conversation`` opened with ~470 lines of straight-line setup before the
+tool-calling loop ever started: stdio guarding, runtime-main wiring, retry-counter
+resets, user-message sanitization, todo/nudge-counter hydration, system-prompt
+restore-or-build, crash-resilience persistence, preflight context compression, the
+``pre_llm_call`` plugin hook, and external-memory prefetch.
+
+All of that is *prologue* — it runs once per turn, has no back-references into the
+loop, and produces a fixed set of values the loop then consumes. ``TurnContext``
+captures those produced values; ``build_turn_context`` performs the setup work and
+returns one. ``run_conversation`` is left to unpack the context and run the loop,
+shrinking the orchestrator by the full prologue.
+
+The builder still mutates ``agent`` heavily (counters, thread id, cached prompt,
+session DB) exactly as the inline code did — those side effects are the point. The
+``TurnContext`` it returns carries only the *locals* the loop reads back.
+
+Behavior is identical to the original inline prologue; this is a pure
+move-and-name refactor with no semantic change.

+"""Post-loop turn finalization for ``run_conversation``.
+
+Extracted from ``agent/conversation_loop.py`` as part of the god-file
+decomposition campaign (``~/.hermes/plans/god-file-decomposition.md``, Phase 1
+step 4 — the post-loop ``TurnFinalizer`` seam). ``run_conversation``'s tail
+(everything after the main tool-calling ``while`` loop) is lifted here verbatim:
+budget-exhaustion summary, trajectory save, session persist, turn diagnostics,
+response transforms, result-dict assembly, steer drain, and the memory/skill
+review trigger.
+
+Behavior-neutral: the body is moved unchanged. All ``agent.*`` side effects fire
+exactly as before; only the post-loop *locals* are passed in as keyword args, and
+the assembled ``result`` dict is returned to ``run_conversation`` which returns it
+to the caller. The function is synchronous with a single return — mirroring the
+region it replaces (no awaits, no early returns).
+
+Module ``logger`` is imported lazily inside the body (``from
+agent.conversation_loop import logger``) so this module never imports
+``agent.conversation_loop`` at import time -> no import cycle, and the log records
+keep the exact logger name (``"agent.conversation_loop"``).

+"""Per-attempt recovery bookkeeping for the conversation turn loop.
+
+The inner retry loop in ``run_conversation`` (``while retry_count <
+max_retries``) makes several distinct recovery attempts on a single model API
+call: a credential-pool 429 retry, a per-provider OAuth refresh (codex,
+anthropic, nous, copilot), a long-context compression restart, a length-
+continuation restart, and a handful of format-recovery branches (thinking-
+signature stripping, multimodal-tool-content stripping, llama.cpp grammar
+fallback, image shrink, invalid-encrypted-content, 1M-beta header).
+
+Each of those branches is guarded by a one-shot boolean so it fires at most
+once per attempt. They used to be ~16 bare ``*_attempted`` / ``has_retried_*``
+/ ``restart_with_*`` locals declared inline before the loop and threaded
+through its 2,400-line body. ``TurnRetryState`` collapses them into one object
+the loop mutates in place (``state.codex_auth_retry_attempted = True``), giving
+the recovery bookkeeping a single named, testable home.
+
+Loop-control variables (``retry_count``, ``max_retries``,
+``max_compression_attempts``) intentionally stay as plain locals — they are the
+``while`` mechanics, not recovery bookkeeping, and putting them on the object
+would add indirection without clarifying anything.
+

+# Desktop Design System
+
+Conventions for the Electron desktop app (`apps/desktop`). Read this before
+adding a component, overlay, or style. The rule of thumb: **one source per
+concern, tokens over literals, flat over boxed.** If you reach for a raw color,
+a one-off shadow, a bespoke button, or a hardcoded `px-*` on a control — stop,
+there's already a primitive for it.
+
+## Principles
+
+1. **Flat, not boxed.** No card-in-card, no divider borders inside a panel.
+   Group with whitespace and a single hairline, never nested rounded boxes.
+2. **Borderless + shadow for elevation.** Overlays float on `shadow-nous` + a
+   `--stroke-nous` hairline, not hard borders.
+3. **One primitive per concern.** One `Button`, one set of control variants,
+   one `SearchField`, one `Loader`, one `ErrorState`. Migrate onto them; don't
+   fork.
+4. **Tokens, not literals.** Reference CSS vars (`--ui-*`, `--shadow-nous`,
+   `--theme-*`), never raw hex / ad-hoc rgba in components.
+5. **Style lives in the primitive.** Variants and sizes own padding, radius,
+   color, chrome. Call sites pass a `variant`/`size`, not `className` overrides
+   that re-specify those.
+
+## Surfaces & elevation
+
+Every overlay / dialog / toast (boot-failure, install, notifications,
+model-picker, onboarding, prompt-overlays, updates, base `Dialog`) uses:
+
+```
+shadow-nous           /* downward-weighted, layered contact→ambient falloff */
+border-(--stroke-nous) /* currentColor hairline, theme-adaptive */
+```
+
+Both are CSS vars in `src/styles.css` — tune in one place, everything inherits.
+Don't add per-overlay `shadow-[…]` or `border-(--ui-stroke-secondary)`
+one-offs; if elevation needs to change, change the token.
+
+## Stroke & color tokens
+
+| Token | Use |
+| --- | --- |
+| `--ui-stroke-primary…quaternary` | hairlines, in descending strength |
+| `--ui-stroke-tertiary` | the default in-panel divider / list hairline |
+| `--stroke-nous` | the overlay hairline (pairs with `shadow-nous`) |
+| `--ui-text-primary / -secondary / -tertiary` | text hierarchy |
+| `--ui-bg-quaternary` | soft control fill (secondary button) |
+| `--chrome-action-hover` | hover fill for quiet controls |
+| `--theme-primary`, `--ui-accent` | brand/accent |
+
+Never hardcode `border-gray-*`, `bg-white`, `text-black`, etc. The white tile in
+`BrandMark` is the one sanctioned literal (the mark needs a fixed backdrop).
+
+## Buttons — one component
+
+`src/components/ui/button.tsx` is the single source. Pick a `variant` + `size`;
+do **not** pass `h-*`, `px-*`, `py-*`, or icon-size overrides.
+
+**Variants:** `default` (primary), `destructive`, `secondary` (soft fill —
+the default non-primary look), `outline` (transparent + 1px inset ring, no
+fill/shadow), `ghost`, `link`, `text` (boxless quiet inline — "Cancel",
+"Clear"), `textStrong` (bold underlined inline affordance — "Change",
+"Open logs").
+
+**Sizes:** `default`, `xs`, `sm`, `lg`, `inline` (flush, zero box — for buttons
+that sit inside a heading/sentence; replaces `h-auto px-0 py-0`), and the icon
+family `icon` / `icon-xs` / `icon-sm` / `icon-lg` / `icon-titlebar`.
+
+Notes:
+- Text buttons are square (no radius) and sized by padding + line-height (no
+  fixed heights). Only icon buttons carry the shared 4px radius.
+- SVGs inherit `size-3.5` (`size-3` at `xs`). Don't re-set icon size.
+- Polymorph with `asChild` when the button must render as a link/Slot.
+
+## Form controls
+
+- **`controlVariants`** (`src/components/ui/control.ts`) is the shared shape for
+  `Input` / `Textarea` / `SelectTrigger`. New text-entry controls compose it.
+- **`SearchField`** — borderless, underline-on-focus, auto-width. The only
+  search input. Don't build boxed search bars; don't wrap it in a bordered tile.
+  Empty lists hide their search field.
+- **`SegmentedControl`** — the choice control for small mutually-exclusive sets
+  (color mode, tool-call display, usage period). Replaces radio piles and
+  pill rows.
+- **`Switch`** (`size="xs"`) — bare, with `aria-label`. No bordered text wrapper.
+
+## Layout
+
+- **Gutters:** `PAGE_INSET_X` (`src/app/layout-constants.ts`) for page side
+  padding; `PAGE_INSET_NEG_X` to bleed a child to the edge. Don't hardcode
+  `px-6`/`px-8` on pages.
+- **Master/detail overlays:** `OverlaySplitLayout` + `OverlaySidebar` /
+  `OverlayMain`. Cron, profiles, etc. ride this — don't rebuild a titlebar
+  shell.
+- **Rows:** `ListRow` (settings `primitives.tsx`) for label/description/action
+  rows. Flat, flush-left; no per-row indentation that fights flush headers.
+- **No dividers between rows** unless the list genuinely needs them; prefer
+  spacing. When you do need one, it's a single `--ui-stroke-tertiary` hairline.
+
+## Feedback & empty/error/loading states
+
+- **Loading:** `Loader` (`src/components/ui/loader.tsx`) — animated math/ascii
+  curves (`lemniscate-bloom` for long ops). Never ship the literal text
+  "Loading…".
+- **Errors:** `ErrorState` + the canonical `ErrorIcon` (no bg chip). One look
+  for the React boundary, in-dialog errors, and the boot-failure banner. Pass
+  nodes for title/description so Radix `DialogTitle`/`Description` can flow
+  through for a11y.
+- **Logs:** `LogView` — no bg, hairline border, tight padding, small mono.
+  Every place we surface raw logs uses it.
+- **Empty:** `EmptyState` / `EmptyPanel` — don't hand-roll centered empties.
+
+## Iconography & brand
+
+- **`Codicon`** is the icon set. No mixing icon libraries inline.
+- **`BrandMark`** (`src/components/brand-mark.tsx`) is the brand glyph — the
+  `nous-girl` mark on a white tile, softly rounded, identical in light/dark.
+  It replaced scattered Sparkles glyphs in updates / onboarding / about. Use it
+  for hero/brand moments; don't reintroduce decorative star/sparkle icons.
+
+## Motion
+
+- Quick, functional transitions (~100ms on controls). Respect
+  `prefers-reduced-motion` for anything beyond a fade.
+- Choreographed exits (e.g. onboarding's "matrix" fade-down) stagger per-element
+  then settle the surface — the outer container's fade is *delayed* so it
+  doesn't swallow the inner animation. Don't let a global fade race the detail.
+
+## i18n
+
+- Every user-facing string goes through `useI18n()` (`src/i18n/context.tsx`).
+  No literals in JSX.
+- **Update all locales together** — `en`, `ja`, `zh`, `zh-hant`. A string change
+  in `en.ts` that skips the others is a regression (drifted punctuation,
+  stale labels). Keep trailing-punctuation and tone consistent across all four.
+
+## State (TypeScript)
+
+Mirrors the repo TS style (see root `AGENTS.md`):
+
+- Shared/cross-component state → small **nanostores**, not prop-drilling.
+  Each feature owns its atoms; shared atoms live in `src/store`.
+- Rendering components subscribe with `useStore`; non-render actions read with
+  `$atom.get()`.
+- Colocated action modules over god hooks. A hook owns one narrow job.
+- Keep persistence beside the atom that owns it. Route roots stay thin.
+- Prefer `interface` for public props; extend React primitives
+  (`React.ComponentProps<'button'>`, `Omit<…>`).
+
+## Affordances
+
+- `cursor-pointer` at the primitive level (Button, dropdown/select) — don't
+  hardcode it per call site.
+- Global focus-ring reset; titlebar actions have no active-background state.
+- `Esc` closes every dismissable overlay/dialog (install/onboarding excluded);
+  close is an x-icon, not the word "Close".
+
+## Before you add something — checklist
+
+- [ ] Reuse a primitive (`Button`, `SearchField`, `SegmentedControl`,
+      `ListRow`, `Loader`, `ErrorState`, `LogView`) instead of forking one?
+- [ ] Tokens (`--ui-*`, `shadow-nous`, `--stroke-nous`) — zero raw colors /
+      one-off shadows?
+- [ ] No `className` overriding a primitive's padding / size / radius / chrome?
+- [ ] Overlay uses `shadow-nous` + `border-(--stroke-nous)`, no hard border?
+- [ ] Flat — no card-in-card, no gratuitous row dividers?
+- [ ] All four locales updated for any new/changed string?
+- [ ] `cursor-pointer`, focus ring, and `Esc`-to-close behave?

+ * Pure, electron-free helpers for the desktop Chat GUI uninstaller. These map

+ * resolve the running app bundle/exe so a detached cleanup script can remove
+ * it after the app quits, and build that cleanup script for each OS.
+ *
+ * Kept standalone (no `require('electron')`) so it can be unit-tested with
+ * `node --test` — same pattern as connection-config.cjs / backend-probes.cjs.
+ * main.cjs requires these and wires them into the electron-coupled IPC layer.
+ *
+ * The three modes mirror the CLI's options exactly:
+ *   - 'gui'  → remove ONLY the Chat GUI, keep the agent + all user data.
+ *              `hermes uninstall --gui --yes`
+ *   - 'lite' → remove the GUI + agent code, KEEP user data (config / sessions
+ *              / .env) for a future reinstall. `hermes uninstall --yes`
+ *   - 'full' → remove everything: GUI + agent + all user data.
+ *              `hermes uninstall --full --yes`
+ *
+ * Why a detached cleanup script: 'lite'/'full' delete the very venv the

+ * app bundle (locked on macOS/Windows while the process is alive). So we hand
+ * the work to a detached child that waits for this app's PID to exit, runs the

+ * while the venv is torn down. gui-only doesn't touch the venv, so it can use
