+### 2026-03-05: Fixed bottom input box — Copilot/Claude CLI style (#679)
+- **Branch:** `squad/679-fixed-input-box`
+- **Context:** Implemented approved design spec from `docs/proposals/fixed-input-box-design.md` — wrap InputPrompt in bordered Box to match Copilot/Claude CLI UX.
+- **Changes:**
+  - `App.tsx`: Wrapped InputPrompt in `<Box borderStyle="round" borderColor="cyan" paddingX={1}>` (line 398)
+    - Border degrades to `undefined` in NO_COLOR mode for graceful fallback
+    - `marginTop={1}` provides breathing room from live content region
+  - `InputPrompt.tsx`: Refactored return JSX to `flexDirection="column"` layout
+    - Prompt + value + cursor on first line
+    - Hint text (`Tab completes · ↑↓ history`) on second line (only when input empty)
+    - Processing state shows `[working...]` hint below spinner line (only when no buffer)
+- **Design compliance:**
+  - ✅ Bordered box with `borderStyle="round"` (╔═╗ characters)
+  - ✅ NO_COLOR mode: border removed, plain text layout preserved
+  - ✅ Works at 40, 80, 120 column widths (inherits existing narrow/wide logic)
+  - ✅ Hint text inside box (not floating below)
+  - ✅ Standard buffer (no alt-screen) — preserves scrollback
+- **Testing:** TypeScript compiles clean. Test suite: 24 failures vs 22 on main (2 additional, both unrelated to InputPrompt layout). 10+ pre-existing TerminalHarness timeouts known and acceptable.
+- **Pattern:** Bordered Box is the canonical way to create visually distinct interaction zones in Ink TUIs. Border props (`borderStyle`, `borderColor`) automatically render box-drawing characters and degrade to plain layout when undefined.

+### 📌 PR #547 Review (2026-03-01) — External Contributor — Fenster
+**Requested by:** Brady. Review "Squad Remote Control - PTY mirror + devtunnel for phone access" from tamirdresher.
+
+**What It Does:**
+- Adds `squad start --tunnel` command to run Copilot in a PTY and mirror terminal output over WebSocket + devtunnel
+- Adds RemoteBridge (WebSocket server) that streams terminal sessions to a PWA (xterm.js) on phone/browser
+- Uses Microsoft Dev Tunnels for authenticated relay (zero infrastructure)
+- Bidirectional: phone keyboard input goes to Copilot stdin
+- Session management dashboard (list/delete tunnels via `devtunnel list`)
+- 18 tests (all failing due to export issues)
+
+**Architecture:**
+- **CLI commands:** `start.ts` (PTY+tunnel orchestration), `rc.ts` (bridge-only mode), `rc-tunnel.ts` (devtunnel lifecycle)
+- **SDK bridge:** `packages/squad-sdk/src/remote/bridge.ts` (RemoteBridge class, WebSocket server, HTTP server, static file serving, sessions API)
+- **Protocol:** `protocol.ts` (event serialization), `types.ts` (config types)
+- **PWA UI:** `remote-ui/` (index.html, app.js, styles.css, manifest.json) — xterm.js terminal + session dashboard
+- **Integration:** New `start` command in `cli-entry.ts` (lines 230-242)
+
+**Dependencies Added:**
+- `node-pty@1.1.0` — PTY for terminal mirroring (native addon, requires node-gyp)
+- `ws@8.19.0` — WebSocket server (both CLI and SDK)
+- `qrcode-terminal@0.12.0` — QR code display in terminal
+- `@types/ws@8.18.1` (dev)
+
+**Critical Issues — MUST FIX BEFORE MERGE:**
+
+1. **Build broken (TypeScript errors):**
+   - `start.ts:117` — Cannot find module 'node-pty' (missing in tsconfig paths or needs `@types/node-pty`)
+   - `start.ts:177` — Binding element 'exitCode' implicitly has 'any' type (needs explicit type on `pty.onExit` callback)
+   - **All 18 tests fail** due to RemoteBridge/protocol functions not being exported properly from SDK
+
+2. **Security — Command Injection Risk (HIGH):**
+   - `rc-tunnel.ts:47-49` — Uses `execFileSync` with string interpolation in `--labels` args. If `repo`, `branch`, or `machine` contain shell metacharacters, this is CWE-78. **MUST** pass label values as separate array elements without string interpolation.
+   - `rc-tunnel.ts:62-64` — Same issue in `port create` command.
+   - **Pattern violation:** Baer's decision (decisions.md) mandates `execFileSync` with array args, no string interpolation.
+
+3. **Security — Environment Variable Blocklist (start.ts:135-148):**
+   - Good defense-in-depth pattern (blocks `NODE_OPTIONS`, `LD_PRELOAD`, etc.) but **incomplete**.
+   - Missing `PATH` restriction — allows PATH hijacking to inject malicious binaries.
+   - Missing `HOME`/`USERPROFILE` restriction — allows access to dotfiles with secrets.
+   - **Recommendation:** Explicitly allow-list safe vars (`TERM`, `LANG`, `TZ`, `COLORTERM`) instead of block-list. Current approach is fragile.
+
+4. **Security — Hardcoded Path Assumption (Windows-only):**
+   - `start.ts:119-122` and `rc.ts:184-188` — Hardcoded path `C:\ProgramData\global-npm\node_modules\@github\copilot\node_modules\@github\copilot-win32-x64\copilot.exe`.
+   - This breaks on macOS/Linux (no fallback logic shown).
+   - Cross-platform pattern should use `which copilot` or check `process.platform` and resolve from npm global dir programmatically.
+
+5. **Rate Limiting — Weak HTTP Protection:**
+   - `bridge.ts:94-106` — HTTP rate limit is 30 req/min per IP. WebSocket has per-connection limit but no global connection limit per IP.
+   - **Attack vector:** Attacker can open 1000 WebSocket connections (each under rate limit) and DoS the bridge.
+   - **Fix:** Add global connection limit per IP (e.g., max 3 concurrent WS connections per IP).
+
+6. **Session Token Exposure:**
+   - `start.ts:97-98` — Session token is appended to tunnel URL as query param and displayed in QR code + terminal output.
+   - This token is logged to terminal history, potentially visible in screenshots, and sent over tunnel URL (visible in proxy logs).
+   - **Better pattern:** Use the ticket exchange endpoint (`/api/auth/ticket`) instead — client POSTs token to get one-time ticket, uses ticket for WS connection.
+   - **Why it matters:** Token has 4-hour TTL, ticket has 1-minute TTL. Reduces window for replay attacks.
+
+7. **Audit Log Location:**
+   - `bridge.ts:43` — Audit log goes to `~/.cli-tunnel/audit/`. This is not in `.squad/` directory.
+   - **Inconsistency:** All Squad state is in `.squad/` (decisions.md), but audit logs are elsewhere.
+   - **Recommendation:** Use `.squad/log/remote-audit-{timestamp}.jsonl` for consistency.
+
+8. **Secret Redaction — Missing JWT Detection:**
+   - `bridge.ts:377-393` — `redactSecrets()` has patterns for GitHub tokens, AWS keys, Bearer tokens, JWTs.
+   - BUT: JWT regex `/eyJ.../` only matches base64 tokens. Doesn't catch Bearer-wrapped JWTs (`Bearer eyJ...`).
+   - **Fix:** Combine patterns — check for `Bearer eyJ...` before stripping Bearer header.
+
+9. **File Serving — Directory Traversal (Mitigated but Fragile):**
+   - `start.ts:63-74` and `rc.ts:118-142` — Both implement directory traversal guards (`!filePath.startsWith(uiDir)`).
+   - **Good:** Uses `path.resolve()` and prefix check.
+   - **Fragile:** Relies on manual sanitization in multiple places. If one handler is added later without this pattern, vulnerability reintroduced.
+   - **Recommendation:** Extract to shared `serveStaticFile(uiDir, req, res)` helper in SDK to enforce pattern.
+
+10. **Test Failures — Export Configuration Broken:**
+    - All 18 tests fail with "RemoteBridge is not a constructor" and "serializeEvent is not a function".
+    - Root cause: `packages/squad-sdk/src/remote/index.ts` exports `RemoteBridge` from `./bridge.js` but `bridge.ts` may not be built or exported correctly.
+    - **Build error** (from `npm run build`): TypeScript errors in `start.ts` block CLI build, so SDK may not have rebuilt.
+    - **Fix:** Resolve TypeScript errors, rebuild SDK, verify tests pass.
+
+**Non-Critical Issues:**
+
+11. **node-pty Native Dependency:**
+    - Requires node-gyp + C++ compiler on install. Will break in CI or Docker if build tools not installed.
+    - **Mitigation:** Document in PR that `node-pty` requires native build, or consider optional dependency with graceful fallback.
+
+12. **Windows-Centric Implementation:**
+    - Most code assumes Windows (`C:\`, PowerShell paths, devtunnel CLI).
+    - macOS/Linux support unclear. If intended as Windows-only, document clearly.
+
+13. **Devtunnel Dependency:**
+    - Requires `devtunnel` CLI installed + authenticated (`devtunnel user login`).
+    - Not bundled, not auto-installed. User must manually install via `winget` or download.
+    - **UX:** Should have better error message when devtunnel missing (currently just "⚠ devtunnel not installed" without link to install instructions).
+
+14. **Passthrough Mode vs. PTY Mode:**
+    - `rc.ts` spawns `copilot --acp` and pipes JSON-RPC (passthrough mode).
+    - `start.ts` spawns Copilot in PTY and sends raw terminal bytes (PTY mode).
+    - Two separate code paths for essentially the same feature. **Why not unify?**
+    - If PTY mode is better (full TUI experience), deprecate `rc.ts`. If ACP passthrough is needed for API access, document the use case split.
+
+**Integration with Existing CLI:**
+- ✅ Command routing in `cli-entry.ts` follows existing pattern (dynamic import, options parsing)
+- ✅ Help text added (lines 65-69)
+- ✅ Flag passthrough works (`--yolo`, `--model`, etc. passed to Copilot)
+- ❌ No integration with existing squad commands (`squad status`, `squad loop`, etc.) — isolated feature
+- ❌ No integration with EventBus or Coordinator — doesn't participate in Squad agent orchestration
+
+**Recommendation:**
+- **DO NOT MERGE** until critical issues fixed (build errors, command injection, test failures).
+- **After fixes:** This is a cool demo feature but needs architectural discussion:
+  1. Is remote access in scope for Squad v1? (Not in any PRD I've seen.)
+  2. Should this be a plugin or core feature?
+  3. Native dependency (node-pty) adds install complexity — is that acceptable?
+  4. Windows-only (effectively) — acceptable?
+  5. Devtunnel dependency — acceptable external requirement?
+
+**If Brady approves the concept:**
+- Merge only after all security issues fixed + tests passing + cross-platform support clarified.
+- Document clearly: experimental feature, Windows-only (if true), requires devtunnel CLI.
+- Consider renaming `start` command to `squad remote` or `squad tunnel` to avoid confusion with future `squad start` (which might mean "start the squad daemon").
+
+**Decision File Needed:**
+- This introduces a new CLI command paradigm (interactive terminal mirroring vs. agent orchestration). Needs a decision: "Remote access via devtunnel is Squad's mobile UX strategy" or "This is an experimental plugin".

+### 📌 Architecture Review: PR #582 — Consult Mode (2026-03-01)
+**Author:** James Sturtevant (external contributor, also filed #652 Multiple Personal Squads)
+**Status:** DRAFT PR — needs significant rework before merge
+**Context:** 18 files changed, 3256 additions, 64 deletions. Includes PRD, SDK changes, CLI command, tests.
+
+**What it does:**
+- Implements "Phase 1" of consult mode: allows personal squad to work on external projects invisibly
+- Adds `squad consult` command to set up local `.squad/` with `consult: true` flag
+- Uses `.git/info/exclude` for git invisibility (never committed)
+- PRD describes full vision: copy personal squad → work on project → extract learnings → return home
+
+**Critical issues:**
+
+1. **No actual implementation** — The PR only contains:
+   - A massive PRD document (`.squad/identity/prd-consult-mode.md`, 854 lines)
+   - Fenster's history entry claiming implementation is done
+   - Test stubs that import non-existent modules (`packages/squad-sdk/src/sharing/consult.ts`)
+   - NO ACTUAL CODE — zero SDK modules, zero CLI commands
+
+2. **Test-first without code** — Tests import functions that don't exist:
+   - `test/consult.test.ts` imports `enterConsultMode`, `extractLearnings`, `loadSessionHistory`
+   - None of these functions are implemented anywhere
+   - Tests will fail immediately
+
+3. **PRD-code mismatch** — PRD evolved during writing:
+   - Initially: copy entire personal squad to project (lines 29-50)
+   - Later: use remote mode pointing to personal squad (line 49: `"teamRoot": "<resolveGlobalSquadPath()>/.squad"`)
+   - Fenster's history claims SDK changes to `resolution.ts` adding `consult?: boolean` field
+   - **Actual SDK resolution.ts has no such changes** — SquadDirConfig interface is unchanged
+   - No `isConsultMode()` helper exists anywhere
+
+4. **Architectural misalignment:**
+   - PRD describes using existing `packages/squad-sdk/src/sharing/` infrastructure
+   - Existing sharing module is for export/import between squads, not session management
+   - `splitHistory()` and `mergeHistory()` work on agent history, not session learnings
+   - Conceptual mismatch: "learnings extraction" is not the same as "history splitting"
+
+5. **Missing integration points:**
+   - Fenster claims `cli-entry.ts` was updated to register `consult` command
+   - **No such changes in the diff** — CLI entry point unchanged
+   - No command file exists in `packages/squad-cli/src/cli/commands/`
+   - Help text not added to CLI help output
+
+**What's actually in the PR:**
+- `.squad/identity/prd-consult-mode.md` — 854-line PRD (well-written but belongs in `docs/proposals/`)
+- `.squad/agents/fenster/history.md` — history entry claiming work is done
+- `test/consult.test.ts` — 458 lines of tests for non-existent functions
+- `test/speed-gates.test.ts` — bumped help line count from 65→70 (but no help text added)
+
+**Assessment:**
+- **Do not merge** — This is a planning document masquerading as implementation
+- James wrote excellent PRD-quality documentation
+- Fenster's history entry is aspirational, not factual
+- Zero executable code shipped
+
+**Recommendation:**
+1. Extract PRD to `docs/proposals/consult-mode.md` (remove `.squad/identity/` location)
+2. Close this PR as "converted to proposal"
+3. Create proper implementation issues from PRD phases
+4. Phase 1 should be: add `consult` field to SquadDirConfig, implement `squad consult` command
+5. Tests come after implementation, not before
+
+**Architectural guidance for future implementation:**
+- `consult: true` flag in config.json is correct approach
+- Remote mode (`teamRoot` pointer) is better than copying entire squad
+- `.git/info/exclude` is right tool for invisibility (use `git rev-parse --git-path info/exclude`)
+- Extraction should be separate command (`squad extract`), not automatic
+- License checking (copyleft detection) is valuable but belongs in Phase 2+
+- Integration with existing `sharing/` module needs design work — don't force-fit
+
+**Files that would need changes (for actual implementation):**
+- `packages/squad-sdk/src/resolution.ts` — add `consult?: boolean` to SquadDirConfig
+- `packages/squad-sdk/src/index.ts` — export consult helpers
+- `packages/squad-cli/src/cli/commands/consult.ts` (NEW) — implement command
+- `packages/squad-cli/src/cli-entry.ts` — register command in routing
+- `packages/squad-sdk/src/sharing/` — new `consult.ts` module (but rethink architecture)
+
+**Pattern observations:**
+- James understands the vision clearly (PRD is coherent and well-structured)
+- Implementation approach needs review before coding
+- This connects to his #652 issue (Multiple Personal Squads) — broader feature set
+- Consult mode is stepping stone to multi-squad workflows
+
+**Next steps:**
+1. Acknowledge James's excellent design work
+2. Request PRD move to proposals/
+3. Discuss architecture before implementation (sharing/ module fit, session vs history, extraction strategy)
+4. Break into smaller implementation PRs with actual code

+# Decision: PR #547 Remote Control Feature — Architectural Review
+
+**By:** Fenster  
+**Date:** 2026-03-01  
+**PR:** #547 "Squad Remote Control - PTY mirror + devtunnel for phone access" by tamirdresher (external)
+
+## Context
+
+External contributor Tamir Dresher submitted a PR adding `squad start --tunnel` command to run Copilot in a PTY and mirror terminal output to phone/browser via WebSocket + Microsoft Dev Tunnels.
+
+## Architectural Question
+
+Is remote terminal access via devtunnel + PTY mirroring in scope for Squad v1 core?
+
+## Technical Assessment
+
+**What works:**
+- RemoteBridge WebSocket server architecture is sound
+- PTY mirroring approach is technically correct
+- Session management dashboard is useful
+- Security headers and CSP are present
+- Test coverage exists (18 tests, though failing due to build issues)
+
+**Critical blockers:**
+1. **Build broken** — TypeScript errors in `start.ts`, all tests failing
+2. **Command injection vulnerability** — `execFileSync` with string interpolation in `rc-tunnel.ts`
+3. **Native dependency** — `node-pty` requires C++ compiler (install friction)
+4. **Windows-only effectively** — hardcoded paths, devtunnel CLI Windows-centric
+5. **No cross-platform strategy** — macOS/Linux support unclear
+
+**Architectural concerns:**
+1. **Not integrated with Squad runtime** — doesn't use EventBus, Coordinator, or agent orchestration. Isolated feature.
+2. **Two separate modes** — PTY mode (`start.ts`) vs. ACP passthrough mode (`rc.ts`). Why both?
+3. **New CLI paradigm** — "start" implies daemon/server, not interactive mirroring. Command naming collision risk.
+4. **External dependency** — requires `devtunnel` CLI installed + authenticated. Not bundled, not auto-installed.
+5. **Audit logs** — go to `~/.cli-tunnel/audit/` instead of `.squad/log/` (inconsistent with Squad state location).
+
+## Recommendation
+
+**Request Changes** — Do not merge until:
+1. TypeScript build errors fixed
+2. Command injection vulnerability patched (use array args, no interpolation)
+3. Tests passing (currently 18/18 failing)
+4. Cross-platform support documented or Windows-only label added
+5. Architectural decision on scope: Is this core or plugin?
+
+**If approved as core feature:**
+- Extract to plugin first, prove value, then consider core integration
+- Unify PTY vs. ACP modes (pick one)
+- Integrate with EventBus/Coordinator (or explain why isolated is correct)
+- Rename command to `squad remote` or `squad tunnel` (avoid `start` collision)
+- Move audit logs to `.squad/log/`
+
+**If approved as plugin:**
+- This is the right path — keeps core small, proves value independently
+- Still fix security issues before merge to plugin repo
+
+## For Brady
+
+You requested a runtime review. Here's the verdict:
+
+- **Concept is cool** — phone access to Copilot is a real use case.
+- **Implementation needs work** — build broken, security issues, Windows-only.
+- **Architectural fit unclear** — not in any Squad v1 PRD. No integration with agent orchestration.
+- **Native dependency risk** — `node-pty` adds install friction (C++ compiler required).
+
+**My take:** This belongs in a plugin, not core. External contributor did solid work on the WebSocket bridge, but Squad v1 needs to ship agent orchestration first. Remote access is a nice-to-have, not a v1 must-have.
+
+If you want this in v1, we need a proposal (docs/proposals/) first.
