Subject: [PATCH 01/20] fix: make LLM actually use spawn/subagent in
 orchestration mode
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The LLM never called spawn even with --orchestration enabled due to
five compounding issues:

1. Identity said "helpful assistant" instead of "conductor" — reframed
   conditionally when orchestration is active
2. Plan executing instruction said "work through steps" — replaced with
   "delegate steps via spawn" in orchestration mode
3. SubagentTool (blocking) was referenced in guidance but never registered
   — now wired up alongside SpawnTool
4. No iteration reminder to use spawn — added orchestration nudge that
   fires on iteration 1 and every 3rd iteration during plan execution
5. Guidance was abstract with no examples — added preset table and
   concrete spawn/subagent call examples
6. Orchestration section in MEMORY.md was dropped from plan context —
   now extracted via existing extractSection()

All changes gated behind orchestrationEnabled / Subagents.Enabled.
Non-orchestration mode is completely unchanged.

Subject: [PATCH 02/20] feat(miniapp): add heartbeat pigeon to Orch canvas
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add 🕊️ as a permanent heartbeat character at MAP_POSITIONS.heartbeat (x=230, y=58)
- Separate heartbeat from secretary: secretary now represents plan mode,
  pigeon represents periodic heartbeat sessions
- Pigeon is always alive (permanent); GC returns it to idle without hiding
- Pigeon flips direction periodically when stationary (720ms idle /
  480ms waiting / 280ms toolcall) and faces movement direction when moving
- Add orch-badge-heartbeat (HB) to left panel

- Conductor is now permanent (alive=true always); GC transitions to
  user_waiting state instead of hiding the character
- Status emoji floats above conductor head: 🤔 thinking, ⌨ toolcall, ⏳ user_waiting
- user_waiting renders with a subtle lavender glow (rgba 167,139,250)
- _orchSetState accepts optional tool param; agent_state events now pass ev.tool
- Secretary remains plan-mode-dependent (alive=false on GC)

- Add ReportStateChange calls in loop.go at plan review/executing/completed transitions
- Update index.html statusText/glow for all 4 plan states (📋🔍▶️✅)

Subject: [PATCH 05/20] fix(miniapp): pigeon always visible; secretary shows
 only during plan mode

- Add fallback position for heartbeat pigeon so stale cached map.js
  (missing MAP_POSITIONS.heartbeat) no longer renders at NaN coords
- Secretary starts alive=false; appears/disappears in sync with
  conductor plan_* state changes via _orchSetState

Subject: [PATCH 08/20] feat(sandbox): restrict curl/wget to localhost and RFC
 1918 in all exec presets

Subagents creating servers could not verify their own work because
curl/wget had no access to localhost. This adds local-network-only
curl/wget access to all exec-capable presets:

- coder/worker: curl|wget added to exec allowlist (previously absent)
- analyst/coordinator: existing curl|wget allowlist kept as-is
- All exec presets: ExecPolicy.LocalNetOnly=true enforced at guardCommand

Uses net.ParseIP + IP.IsLoopback() + IP.IsPrivate() (Go stdlib) for
host validation. DNS resolution is intentionally avoided to prevent
DNS rebinding. External HTTP remains available via the web_fetch tool.

Subject: [PATCH 09/20] fix(sandbox): allow /dev/null and device files in
 workspace path guard

curl -o /dev/null -w "%{http_code}" is a common pattern for HTTP status
checks. The workspace path guard was incorrectly blocking it because
/dev/null is an absolute path outside the working directory.

Character and block device files pose no workspace-escape risk, so they
are now exempt from the outside-working-dir check (same logic as
executable binaries).

Subject: [PATCH 10/20] fix(sandbox): allow /dev/* paths in workspace guard
 (not just device files)

/dev/null, /dev/urandom etc. are useful system resources that pose no
workspace-escape risk. Replacing the os.ModeDevice stat check with a
simple /dev/ prefix match is simpler and more general.

Subject: [PATCH 11/20] fix(orch): improve spawn/subagent tool calling adoption
 for less capable models

Replace pseudo-syntax examples with JSON Tool:/Arguments: format in system
prompt and orchestration reminders. Add parameter hints to tool summaries,
improve error messages with usage examples, and strengthen delegation nudges.

Subject: [PATCH 12/20] fix(spawn): separate preset validation from agent ID
 allowlist check

Preset names (scout, analyst, etc.) were being sent through the agent ID
allowlist checker, causing all preset-based spawns to be rejected with
"not allowed to spawn agent". Now presets are validated via IsValidPreset()
and only agent_id goes through the allowlist.

Subject: [PATCH 13/20] fix(plan): auto-advance to next phase when current
 phase completes

During plan execution, completing the last step of a phase would call
AdvancePhase() but the LLM loop had already returned, so work on the
next phase never started. Wrap runLLMIteration + phase checks in a for
loop that rebuilds the system prompt and re-enters the LLM iteration
when a phase boundary is crossed. Capped at 10 transitions as a safety
guard.

Subject: [PATCH 14/20] fix(agent): suppress plan nudge and SkipPlaceholder for
 system messages

When a subagent completes, processSystemMessage triggers runAgentLoop
with SendResponse: true. This caused three problems:

1. The plan-execution nudge fired, forcing the LLM into unnecessary
   iterations when it was correctly waiting for user input
2. The response was sent without SkipPlaceholder, consuming the
   Telegram "Thinking..." placeholder and corrupting status messages
3. Tool call results from the nudged iterations leaked into the chat

Add SystemMessage flag to processOptions. When set:
- Plan continuation nudge is suppressed in runLLMIteration
- Outbound response uses SkipPlaceholder: true

Subject: [PATCH 15/20] fix(sandbox): create per-subagent ExecTool to avoid
 leaking allowPatterns

The shared ExecTool instance (sm.execTool) was mutated by
SetAllowPatterns when spawning subagents, which leaked sandbox
restrictions to the conductor. Basic commands like pwd and ls were
blocked on the main agent after any subagent spawned with a preset.

Create a new ExecTool per subagent instead of sharing a single
instance. Remove the now-unused execTool field from SubagentManager.

Subject: [PATCH 16/20] refactor(sandbox): replace regex exec allowlist with
 command prefix dictionary
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the regex-based presetExecPatterns with presetAllowRules, a
dictionary of command prefix strings (e.g. "go test", "pnpm run lint").

Benefits:
- Readable at a glance without decoding regex alternations
- No regex compilation; matching is a simple word-prefix check
- Easy to extend with new commands per preset
- Each preset's permissions are an explicit list

ExecPolicy.AllowPattern (string) → ExecPolicy.AllowRules ([]string).
ExecTool.SetAllowPatterns → ExecTool.SetAllowRules.
Tests rewritten to use guardCommand directly instead of regex matching.

Subject: [PATCH 17/20] fix(agent): stop running LLM loop for subagent
 completions

processSystemMessage was calling runAgentLoop for every subagent
completion, which caused:
- Chat spam: each completion triggered a full LLM response sent to user
- Token waste: unnecessary LLM iterations for each result
- Placeholder corruption: responses consumed Telegram status messages

Replace with a lightweight path: inject the subagent result into
session history and send a brief SkipPlaceholder notification. The
conductor sees accumulated results on its next turn.

Remove the now-unused SystemMessage field from processOptions.

Subject: [PATCH 20/20] style: fix remaining golines and gofmt lint issues

- spawn.go:97: break long fmt.Sprintf into multi-line
- loop.go:1179: break long if-condition into multi-line
- loop.go:2742: map[string]interface{} -> map[string]any (gofmt rewrite)
