v1.8.1: global agents + parser robustness + WS reconnect toast

Builtins move out of code into /data/AGENTS.md (always-on, mounted ro
into the container); per-project AGENTS.md is now an optional override.
agents.ts merges global + project entries with project-wins-by-name and
caches per-source mtimes (60s TTL). Parser switches to per-block
try/catch and returns AgentsResponse { agents, errors[] } so one
malformed block no longer fails the file. AgentPicker shows a
non-blocking amber chip listing skipped blocks and only fires a gray
toast when zero agents loaded.

WS reconnect UX (useUserEvents + useSessionStream) now silent on the
first disconnect; createWsReconnectToast escalates to gray after 3
failures or 15 s, then to red with a Retry Now action after 60 s.
useSessionStream also gained the exponential-backoff reconnect it was
missing.

+## Code Reviewer
+---
+temperature: 0.3
+tools: [view_file, list_dir, grep, find_files]
+description: Reviews code for bugs, security issues, and maintainability. Read-only.
+---
+You review code. Find real problems, not style nits.
+
+Process:
+1. Read the file(s) in question with view_file. If a diff is provided, read surrounding context too.
+2. Use grep/find_files to check how changed symbols are used elsewhere.
+3. Cite every finding as file:line.
+
+Prioritize in order:
+1. Bugs and logic errors
+2. Security issues (injection, auth bypass, secret leakage, unsafe deserialization, SSRF, path traversal)
+3. Race conditions, error handling, resource leaks
+4. Performance issues with measurable impact
+5. Maintainability (only if it blocks future work)
+
+Skip: formatting, naming preferences, "consider extracting", "add a comment here". The user has a linter.
+
+Output format:
+- Critical: <file:line> — <issue> — <fix>
+- Major: <file:line> — <issue> — <fix>
+- Minor: <file:line> — <issue> — <fix>
+
+If nothing critical or major, say so in one line. Do not pad.
+
+
+## Debugger
+---
+temperature: 0.2
+tools: [view_file, list_dir, grep, find_files]
+description: Diagnoses bugs from error messages, logs, or described symptoms.
+---
+You diagnose bugs. Form a hypothesis, prove it with evidence from the code.
+
+Process:
+1. Restate the symptom in one line. Confirm you understand it.
+2. Read the error/stacktrace. Identify the exact frame where things go wrong.
+3. view_file on that frame. Read 50 lines around it.
+4. grep for callers, related state, recent changes that could explain it.
+5. State the root cause with file:line evidence.
+6. Propose the minimal fix. Note any side effects.
+
+Rules:
+- Never guess. If evidence is missing, say what you need (specific log line, specific file, specific repro step).
+- Distinguish symptom from cause. A null check fixes the symptom; missing init causes it.
+- Off-by-one, race conditions, and silent except blocks are common — check for them.
+- If two plausible causes exist, name both and say what would discriminate.
+
+Output:
+- Symptom: <one line>
+- Root cause: <file:line> — <explanation>
+- Fix: <minimal diff or description>
+- Risk: <what could break>
+
+
+## Refactorer
+---
+temperature: 0.3
+tools: [view_file, list_dir, grep, find_files]
+description: Proposes refactors for clarity, deduplication, or decoupling. Read-only — outputs plans, not edits.
+---
+You propose refactors. You do not apply them. The user applies via OpenCode or Claude Code.
+
+Process:
+1. Read the target file(s).
+2. grep for callers, duplicates, and similar patterns elsewhere in the repo.
+3. Identify the smallest refactor that delivers the goal.
+
+Prioritize:
+1. Deduplication where 3+ sites have near-identical logic
+2. Extracting a function/module when one is doing two unrelated jobs
+3. Decoupling when a change in A forces a change in B unnecessarily
+4. Renaming when a name actively misleads
+
+Reject:
+- Refactors that touch 10+ files for marginal gain
+- "Modernization" with no concrete benefit
+- Abstraction for future flexibility that may never come
+- Style-only changes
+
+Output:
+- Goal: <one line>
+- Scope: <files affected, count of lines roughly>
+- Plan: numbered steps, each one self-contained
+- Risk: <what tests must pass, what could regress>
+- Skip if: <conditions under which this refactor is not worth doing>
+
+
+## Architect
+---
+temperature: 0.5
+tools: [view_file, list_dir, grep, find_files]
+description: Designs new features, modules, or architectural changes. Outputs a build plan.
+---
+You design. You produce build plans, not code.
+
+Process:
+1. Restate the goal in your own words. Confirm constraints (perf, deploy, deps).
+2. list_dir the relevant areas. Read existing patterns — match them unless there's a reason not to.
+3. Decide: extend existing code or add new module. Justify.
+4. Sketch the data flow: inputs → transforms → outputs → side effects.
+5. Identify integration points: DB schema, API surface, env vars, container boundaries.
+6. List failure modes and how the design handles them.
+
+Rules:
+- Reuse before inventing. If a service/lib in the repo already does this, say so.
+- Prefer boring tech. New deps require justification.
+- Tailscale IPs for internal routing. No 0.0.0.0 binds.
+- Least privilege: separate read/write paths, explicit auth gates.
+- State assumptions inline. Do not ask clarifying questions mid-design unless blocked.
+
+Output:
+- Goal
+- Existing code to reuse: <file paths>
+- New code: <file paths, one-line purpose each>
+- Data model changes: <SQL or schema diff>
+- API surface: <endpoints, request/response shapes>
+- Failure modes: <list>
+- Build order: numbered, each step 30-90 min
+
+
+## Security Auditor
+---
+temperature: 0.2
+tools: [view_file, list_dir, grep, find_files]
+description: Audits code for security vulnerabilities. Read-only.
+---
+You audit for security issues. Concrete findings only, no generic warnings.
+
+Process:
+1. Identify the trust boundary: where does untrusted input enter? Where does it leave?
+2. Trace input flow with grep. Mark every transformation.
+3. Check each finding against a real attack scenario.
+
+Look for:
+- Injection: SQL (raw queries, string concat into queries), command (subprocess with shell=True, unescaped args), XSS (unescaped output in HTML/JSX), template injection, NoSQL injection
+- AuthN/AuthZ: missing checks on routes, IDOR (user-supplied IDs without ownership check), JWT misuse (alg=none, weak secret, no expiry), session fixation
+- Secrets: hardcoded keys/passwords, .env in repo, secrets in logs, secrets in error messages
+- Crypto: weak hashes (MD5, SHA1 for passwords), missing salt, predictable randomness (Math.random for tokens), ECB mode, custom crypto
+- Network: SSRF (user URL → server fetch), open CORS, missing CSRF on state-changing requests, plaintext over public network
+- File: path traversal, unrestricted upload type/size, zip slip
+- Deserialization: pickle, yaml.load, eval, exec on user input
+- Resource: missing rate limits on auth/expensive endpoints, unbounded query results
+
+For each finding:
+- Severity: Critical / High / Medium / Low
+- Location: file:line
+- Attack scenario: one sentence describing how an attacker exploits this
+- Fix: minimal change
+
+Skip:
+- Generic "use HTTPS" advice
+- "Consider adding rate limiting" without a specific endpoint
+- CVE-of-the-week scares without proof the code is affected
+
+If the code is clean, say so. Do not invent findings.
+
+
+## Prompt Builder
+---
+temperature: 0.4
+tools: [view_file, list_dir, grep, find_files]
+description: Builds prompts for OpenCode, Claude Code, or BooCode dispatch.
+---
+You write prompts that another coding agent will execute. Your output is the prompt, not the work.
+
+Process:
+1. Ask the user (or read context) for: goal, target repo, target files if known, constraints.
+2. list_dir and view_file the target area. Confirm files exist and are roughly the shape you think.
+3. Identify imports, exports, and conventions in the repo (component layout, error handling style, test framework).
+4. Write the prompt.
+
+Prompt structure:
+- One-line goal at the top
+- Constraints block: don't commit, don't push, don't pull. Use `#careful` and `#nofluff` style hashtags if the target agent honors them
+- Pre-flight: list_dir or grep commands the agent must run before writing (e.g. "run: ls frontend/src/components/ui/ and only import primitives that exist")
+- Files to modify: explicit paths
+- Files to create: explicit paths with one-line purpose
+- Behavior spec: numbered, testable
+- Backup rule: `cp file file.bak-$(date +%Y%m%d)` before any destructive edit
+- Verification: `py_compile`, `tsc --noEmit`, `docker compose up --build -d` — whichever applies
+- Stop conditions: when to halt and report instead of pressing on
+
+Rules:
+- Tailored to the target agent: OpenCode honors hashtag snippets and skills; Claude Code honors CLAUDE.md and slash commands; BooCode batches are written as user-facing markdown
+- Never include credentials or secrets
+- Never instruct the agent to commit or push
+- Include the exact model the user wants if dispatch is via Paseo or BooCode batch
+- For BooLab frontend prompts, always include the "verify shadcn primitives exist" preflight
+
+Output: the prompt, ready to paste. Nothing else.

 ## Workflow
 
 - Sam reviews all diffs and commits manually. Do not commit unless explicitly asked.

 - Fastify global JSON parser tolerates empty bodies (overridden in `index.ts`); bodyless POSTs (archive, unarchive, stop) work without setting `Content-Type` tricks on the client.
 - Event dedup discipline: for any mutation the server publishes via `broker.publishUser`, do NOT add a local `sessionEvents.emit(...)` after the API call — `useUserEvents` forwards the WS frame onto the bus. Frontend mutation handlers must be idempotent (dedup by id, no-op on already-present).

+# BooCode v1.x — Roadmap
+
+Last updated: 2026-05-16
+
+## Overview
+
+BooCode is a standalone code-chat tool at `/opt/boocode/`. Read-only by design — pick a project, chat with a local LLM that has file-inspection tools, get streaming responses over WebSocket.
+
+Live at `https://code.indifferentketchup.com` (Caddy → Authelia → Tailscale → `100.114.205.53:9500`).
+
+**Architectural commitments:**
+
+- No embeddings. The model uses file-view tools (`view_file`, `list_dir`, `grep`, `find_files`) + sidecar analyzers (codecontext, codesight). Walked away from the RAG pipeline May 2026.
+- Read-only in v1.x. Write tools land in BooCoder (separate container, post-v1.x).
+- One Postgres (`boocode_db`), one frontend SPA, container-per-service for new capabilities.
+
+External code lifted from / referenced in: see `boocode_code_review.md` for full inventory.

+
+**Old Batch 12 (codebase indexer w/ Harrier embeddings) — REMOVED.** Replaced by Batch 11/11b sidecar approach. See `boocode_code_review.md` decisions log.
+
+**Batch 9 reordered ahead of 5–8, 10.** Picker mounts in `ChatInput.tsx` toolbar only. SettingsDrawer agent entry rolled into Batch 7 when it lands. No UI dependency on Batches 5/6/7, so it can ship anytime after v1.6.2.
+
+-----
+
+## Batch details (planned / new)
+
+### Batch 9 — Agents (Tier 2, DECOUPLED)
+
+**Spec:** `boocode_batch9.md` with the deltas below.
+
+**Status:** Next up after v1.6.2 merges. Decoupled from Batch 7.
+
+**Deltas from `boocode_batch9.md`:**
+
+1. Builtin defaults in `agents.ts` OMIT the `model` field. Resolution order makes `session.model` win when `agent.model` is null. Spec line 30 example is misleading — do not hardcode any model in builtins.
+2. Builtin defaults are the six agents shipped in `/opt/boocode/AGENTS.md`: **Code Reviewer, Debugger, Refactorer, Architect, Security Auditor, Prompt Builder.** If project root `AGENTS.md` exists, only its agents show. If absent, show the six builtins.
+3. AgentPicker mounts in `ChatInput.tsx` toolbar between ModelPicker and the `+` button. **No `SettingsDrawer.tsx` or `Header.tsx` changes in this batch.**
+4. SettingsDrawer agent entry + Header active-agent badge moved to Batch 7.
+
+**Files to create:**
+
+- `apps/server/src/services/agents.ts` — parser, six builtin defaults, mtime-keyed cache.
+- `apps/server/src/routes/agents.ts` — `GET /api/projects/:id/agents`.
+- `apps/web/src/components/AgentPicker.tsx` — dropdown, matches ModelPicker pattern.
+
+**Files to modify:**
+
+- `apps/server/src/schema.sql` — `ALTER TABLE sessions ADD COLUMN IF NOT EXISTS agent_id TEXT;`
+- `apps/server/src/services/inference.ts` — resolution order: `effective_system_prompt`, `effective_model`, `effective_temperature`, `effective_tools` from session + agent + project. Filter tools array against agent whitelist before sending to llama-swap.
+- `apps/server/src/routes/sessions.ts` — PATCH accepts `agent_id`.
+- `apps/server/src/types/api.ts` — Agent type, extend Session with `agent_id`.
+- `apps/web/src/api/client.ts`, `apps/web/src/api/types.ts` — Agent type, `api.agents.list(projectId)`.
+- `apps/web/src/components/ChatInput.tsx` — mount AgentPicker.
+
+**Testing plan (manual, before locking temps):**
+
+- Drop `/opt/boocode/AGENTS.md` (six agents, no `model` field on any).
+- For each of the 7 keeper models, switch session model and run the same target prompt against each agent. Log tok/s, instruction-following quality.
+- Adjust per-agent temperature in `AGENTS.md` based on results.
+- A/B candidates: qwen3.6-35b-a3b-mxfp4 (daily), qwopus3.6-35b-a3b-q4 (reasoning), qwopus3.5-27b-q4, qwen3.6-27b-ud-q4-xl, nemotron-3-nano-30b, gemma-4-26b-a4b-mxfp4, qwen3-coder-30b-apex.
+
+**Dependencies:** v1.6.2 merged.
+
+-----
+
+### Batch 11 — Architect: codebase map (REVISED)
+
+**Inspiration / lift:** `nmakod/codecontext` (MIT, Go binary).
+
+**What it gives BooCode:** an architect-grade codebase overview without embeddings. Codecontext parses the repo with tree-sitter, extracts symbols, builds import/dependency relationships, and exposes the result via an MCP server with 8 tools. The model gets a structural map of any codebase on demand.
+
+**Why this replaces the original Batch 11 (aider PageRank port):** codecontext is a finished binary in our stack language (Go), with watch mode, incremental updates, framework detection, and git-co-change-based semantic neighborhoods (no embeddings). The aider port would be reimplementing what codecontext already ships.
+
+**Scope:**
+
+- Add `codecontext` sidecar container to `docker-compose.yml`. Mount the project root read-only. One sidecar per BooCode instance — projects are addressed by absolute path.
+- Wire each codecontext MCP tool into BooCode’s `inference/tools.ts` as a native tool the model can call:
+ - `repo_overview(project_id)` → codecontext `get_codebase_overview`
+ - `repo_file_analysis(project_id, path)` → `get_file_analysis`
+ - `repo_symbol_info(project_id, symbol)` → `get_symbol_info`
+ - `repo_search_symbols(project_id, query)` → `search_symbols`
+ - `repo_dependencies(project_id, path)` → `get_dependencies`
+ - `repo_semantic_neighborhoods(project_id, path)` → `get_semantic_neighborhoods` (git co-change)
+ - `repo_framework_analysis(project_id)` → `get_framework_analysis`
+- `path_guard.ts` extension: incorporate `continuedev/continue` `DEFAULT_SECURITY_IGNORE_FILETYPES` so codecontext can’t surface `.env`, `.pem`, keys, etc.
+- Fallback grammars: drop `Aider-AI/aider`‘s `aider/queries/tree-sitter-*.scm` files for any language codecontext doesn’t cover. Use them via an in-process tree-sitter wrapper *only if* a project needs an unsupported language. Defer wrapper build until that’s an actual gap.
+
+**Where it goes:** new `apps/server/src/architect/` directory. No new tables — codecontext maintains its own state on disk. New env: `CODECONTEXT_URL=http://codecontext:8765` (MCP endpoint).
+
+**Decisions to make at recon time:**
+
+- Bundle the binary directly in the BooCode Dockerfile, or run codecontext as its own service? Sidecar is cleaner. Bundle is one less container.
+- How does the model discover codecontext tools — register them statically in the tools registry, or proxy MCP `tools/list` at startup?
+
+**Dependencies:** none. Can ship before Batches 5–10.
+
+-----
+
+### Batch 11b — Architect: repo health (NEW)
+
+**Inspiration / lift:** `spirituslab/codesight` (MIT-ish, TS/Node).
+
+**What it gives BooCode:** complement to Batch 11. Where codecontext answers “what is this codebase,” repo health answers “what’s wrong with this codebase.” Call graph, circular dependency detection, dead code flagging.
+
+**Scope:**
+
+- Port codesight’s `analyze.mjs` analyzer core into `apps/server/src/architect/repo_health.ts`. Drop the VS Code extension shell. Keep:
+ - Symbol extraction (already overlaps codecontext — call codecontext where possible, only redo what’s needed for graph edges).
+ - Call graph builder (function-to-function edges).
+ - Circular dependency detector.
+ - Dead code detector (exported symbols never imported or called).
+- New tool: `repo_health(project_id)` returning `{ circular_dependencies: [...], dead_code: [...] }`. Output respects codesight’s documented false-positive caveats (customElements.define, framework entry points, dynamic imports) — surface those in the tool description so the model doesn’t trust dead-code flags blindly.
+- Cache results in `boocode_db` keyed by `(project_id, file_hashes)`. Invalidate on file change via file-index hash check.
+
+**Decisions:**
+
+- Build it in-process (Node) vs spawn a CLI? In-process is simpler. Spawn matches codecontext sidecar pattern but adds latency.
+
+**Dependencies:** Batch 11 merged (so we can reuse codecontext’s parse output where possible). Can be deferred until after Batches 5–10.
+
+-----
+
+### Batch 12 — Tool approval gating + plan/act mode
+
+**Inspiration / lift:** `cline/cline` (Apache-2.0).
+
+**What it gives BooCode:** per-session control over which tools the model can call. Lays the groundwork for BooCoder by building the gating mechanism before there are any write tools to gate.
+
+**Scope:**
+
+- New column `sessions.tool_approval_mode TEXT` — values: `read_only` (v1.x default), `plan`, `act_auto`, `act_approve`.
+- New column `sessions.approved_tools JSONB` — per-session whitelist for `act_approve` mode.
+- Tool registry refactor: tools tagged `read_only` or `write`. In `read_only` mode (v1.x), write tools never appear in the model’s tools array. In `plan` mode, same — write tools hidden, model produces a plan only. `act_*` modes unlock writes (post-v1.x).
+- UI: mode picker in SettingsDrawer (Batch 7 dependency). Inline indicator in chat header.
+
+**Dependencies:** Batch 7 (SettingsDrawer).
+
+-----
+
+### Batch 13 — Append-only event log
+
+**Inspiration / lift:** `OpenHands/OpenHands` V1 (MIT).
+
+**What it gives BooCode:** replaces the ad-hoc `messages` table semantics with a typed event stream. Unlocks rewind, time-travel, and clean handoff semantics for multi-agent flows.
+
+**Scope:**
+
+- New `session_events` table: `(id, session_id, ts, kind, payload JSONB, parent_id)`. Event kinds: `user_message`, `assistant_message`, `tool_call`, `tool_result`, `pane_action`, `mode_change`, `system`.
+- Existing `messages` table becomes a derived view over `session_events` for backward compatibility, then deprecated over a release.
+- Inference loop emits events instead of mutating message rows.
+- Frontend `useSessionStream` reducer rewritten to consume events.
+
+**Migration is non-trivial.** Plan in a dedicated batch with explicit cutover window.
+
+**Dependencies:** Batches 5 (fork/delete) and 7 (settings) merged. Must not be in flight with other backend work.
+
+-----
+
+### Batch 14 — BooCoder: pending changes
+
+**Inspiration / lift:** `plandex-ai/plandex` (MIT).
+
+**What it gives BooCode:** safe write tools. Edits queue in a virtual layer; nothing touches the filesystem until explicit `/apply`.
+
+**Scope:**
+
+- New container `boocoder` at `100.114.205.53:9502`. Owns write tools (`edit_file`, `create_file`, `delete_file`, `apply_pending`, `rewind`).
+- New table `pending_changes (id, session_id, file_path, diff TEXT, status, created_at)`. Status: `pending`, `applied`, `rejected`.
+- Tools execute against the pending-changes layer, not the filesystem. `apply_pending` is the only path that touches disk. `rewind` rolls back a `pending`-id back to disk state.
+- BooCode chat container stays read-only (`/opt:/opt:ro`). BooCoder mounts `/opt/repos:/opt/repos:rw` and uses git worktree pattern from paseo for isolation.
+- Frontend: new pane kind `pending_diff` shows the queued diff inline with Approve/Reject per chunk.
+
+**Dependencies:** Batches 12 (gating) + 13 (events). Don’t start until both are live.
+
+-----
+
+### Batch 15 — BooCoder runtime isolation
+
+**Inspiration / lift:** `OpenHands/OpenHands` (MIT).
+
+**What it gives BooCode:** per-session Docker sandbox for BooCoder writes. Closes the `/opt:ro` mount risk identified in v1.x open items.
+
+**Scope:**
+
+- Per-session container spawned by BooCoder on first write. Container has only the project’s path mounted, not `/opt`.
+- Container lifecycle: spawn on first write call, idle-timeout after 30 min, recreate on resume.
+- Action execution server pattern: HTTP API inside the container, BooCoder calls in. Standard OpenHands runtime contract.
+
+**Dependencies:** Batch 14.
+
+-----
+
+### Batch 16 — Multi-provider LLM abstraction
+
+**Inspiration / lift:** `earendil-works/pi` `pi-ai` (MIT).
+
+**What it gives BooCode:** optional non-llama-swap inference paths (Anthropic, OpenAI, Mistral direct). Currently we have one provider (llama-swap) and the existing `streamCompletion` is hardcoded to OpenAI-compatible at that endpoint.
+
+**Scope:**
+
+- Provider abstraction: `interface LLMProvider { stream(req): AsyncIterator<Frame> }`.
+- Built-in: llama-swap (current), Anthropic, OpenAI (Codex-style).
+- Per-session `provider_id` column.
+
+**Status:** **Optional. Skip unless a concrete need surfaces.** llama-swap covers daily driver work.
+
+-----
+
+### Batch 17 — Workflow graphs
+
+**Inspiration / lift:** `microsoft/agent-framework` (MIT) — concepts only.
+
+**What it gives BooCode:** multi-agent coordination. Architect → Coder → Reviewer → Verifier handoffs orchestrated by a YAML-defined workflow.
+
+**Status:** **Far future.** Read agent-framework’s `docs/decisions/` ADRs. Don’t port code — Azure/.NET-heavy.
+
+**Dependencies:** Batches 12 (modes), 13 (events). Realistically a v2.x topic.
+
+-----
+
+## Order of operations
+
+Two tracks. Pick one to drive next.
+
+**Track A — Finish v1.x mobile + polish then agents:**
+
+- v1.6.2 ships (in flight)
+- **Batch 9 (agents)** — decoupled, can land next; no UI dependency on 5/6/7
+- Batches 5, 6, 7, 8 in order. Each is small, frontend-heavy, no architecture risk. Batch 7 absorbs SettingsDrawer agent entry.
+
+**Track B — Begin architect capabilities in parallel:**
+
+- Batch 11 (codecontext sidecar) — biggest single capability jump. Frontend stays the same; new tools appear to the model.
+- Batch 11b (repo health) — follow-up.
+- Batch 12 (gating) — sets up everything post-v1.x.
+
+Recommendation: ship v1.6.2, then **Batch 9 (agents)** next so the test bed exists before Track A continues. Then Track A through Batch 7. Batch 11 can run in parallel with Batches 8–10 since 11 has no UI dependency.

+## Decisions log
+
+- **Embeddings dropped from BooCode.** Replaced RAG with file-view tools + sidecar analyzers.
+- **Original Batch 11 (aider PageRank port) replaced** by codecontext sidecar approach.
+- **Original Batch 12 (codebase indexer w/ Harrier) removed** entirely. No embedding infrastructure in BooCode v1.x.
+- **Globstar parked** — not an architect tool, future verify-before-commit candidate only.
+- **codeprysm rejected** — embedding-based; node/edge taxonomy noted as reference if we ever build our own graph.
+- **Batch 9 decoupled from Batch 7 (2026-05-16).** AgentPicker mounts in `ChatInput.tsx` toolbar only. SettingsDrawer agent entry and Header active-agent badge moved to Batch 7. Builtin defaults shipped: six agents (Code Reviewer, Debugger, Refactorer, Architect, Security Auditor, Prompt Builder) with no `model` field — session model wins by default.
+
+-----
+
+## Workflow
+
+Each batch:
+
+1. Verify previous batch merged.
+2. Dispatch via Paseo to Claude Code at `/opt/boocode`.
+3. Claude Code recon → blocking questions → implement → hand back.
+4. Compliance review in separate Claude chat.
+5. Deploy: `docker compose up --build -d`.
+6. Smoke test.
+7. Sam commits and pushes.
+
+Sam reviews all diffs. Sam commits. Never git pull/push/commit on his behalf.
