-## Development Workflow
-
-### 1. Start the API Server
-
-```bash
-cd webber-api
-./wakeup.sh
-```
-
-- **Port:** 8095 (dev), 8086 (production Docker)
-- **Logs:** `webber-api/logs/server.log`
-- **Health check:** `curl http://localhost:8095/health`
-- **API docs:** http://localhost:8095/docs
-
-To stop: `Ctrl+C` or `pkill -f "uvicorn src.main:app"`
-
-### 2. Run Tests
-
-```bash
-# API tests (39 tests)
-cd webber-api
-.venv/bin/python -m pytest tests/ -v
-
-# With coverage
-.venv/bin/python -m pytest tests/ --cov=src
-
-# Single test file
-.venv/bin/python -m pytest tests/test_tools.py -v
-```
-
-### 3. Use the CLI
-
-```bash
-cd webber-cli
-
-# Check API connection
-.venv/bin/webber-cli status
-
-# Explore a directory
-.venv/bin/webber-cli explore "find all python files" -d ../webber-sandbox
-
-# Interactive chat mode
-.venv/bin/webber-cli chat -d ../webber-sandbox
-```
-
-**Note:** The API server must be running for CLI commands to work.

-## Sandbox Management
-
-The sandbox is a swappable test project for functional testing.
-
-### Available Templates
-
-| Template | Description |
-|----------|-------------|
-| `calculator-cli` | Python CLI with intentional bugs (div-by-zero, missing tests) |
-| `empty` | Blank starter project |
-
-### Commands
-
-```bash
-# List available templates
-./sandbox.sh list
-
-# Load a template (clears sandbox, preserves .venv)
-./sandbox.sh load calculator-cli
-
-# Reset to last loaded template
-./sandbox.sh reset
-
-# Save current sandbox as new template
-./sandbox.sh save my-template
-
-# Check current status
-./sandbox.sh status
-```
-
-### After Loading a Template
-
-```bash
-cd webber-sandbox
-source .venv/bin/activate  # Create .venv first if missing
-pip install -r requirements.txt
-
-# Read the tasks
-cat TASKS.md
-
-# Run the project's tests
-pytest tests/ -v
-```
-
----
-
-## Testing Webber's Capabilities
-
-### Scenario: Find bugs in calculator-cli
-
-```bash
-# 1. Load the template
-./sandbox.sh load calculator-cli
-
-# 2. Have Webber explore it
-cd webber-cli
-.venv/bin/webber-cli explore "find all bugs in the code" -d ../webber-sandbox
-
-# 3. Check TASKS.md for expected bugs
-cat ../webber-sandbox/TASKS.md
-```
-
-### Known bugs in calculator-cli:
-- Division by zero not handled (`operations.py:divide`)
-- Invalid operation causes KeyError (`main.py:get_operation`)
-- Power function broken for fractional exponents
-- Missing tests for divide and power functions
-

-## Key Files for Debugging
-
-| File | Purpose |
-|------|---------|
-| `webber-api/logs/server.log` | API server logs |
-| `webber-api/src/domains/agents/explore/prompts.py` | Explore agent system prompts |
-| `webber-api/src/domains/agents/explore/agent.py` | Explore agent implementation |
-| `webber-api/src/ollama/provider.py` | Ollama integration (sanitizes content:null) |
-| `webber-api/docs/COVERAGE.md` | Feature coverage and known issues |

-## Versioning & Releases
-
-Uses prefixed tags:
-- `api/v0.3.0` → Triggers API Docker build
-- `cli/v0.1.0` → Triggers CLI build (future)
-
-```bash
-# API release
-cd webber-api
-# Update version in pyproject.toml
-git add -A && git commit -m "chore: release api v0.3.0"
-git tag api/v0.3.0
-git push origin main --tags
-```
-
----
-
-## Troubleshooting
-
-### API server won't start
-```bash
-# Check if port is in use
-lsof -i :8095
-
-# Kill stuck process
-pkill -f "uvicorn src.main:app"
-```
-
-### CLI can't connect
-```bash
-# Check API is running
-curl http://localhost:8095/health
-
-# Check CLI config
-echo $WEBBER_API_URL  # Should be http://localhost:8095
-```
-
-### Ollama errors
-```bash
-# Check Ollama is running
-curl http://192.168.86.149:11434/api/tags
-
-# Check model is available
-curl http://192.168.86.149:11434/api/tags | grep mistral-nemo
-```
-
-### Tests failing
-```bash
-# Run with verbose output
-cd webber-api
-.venv/bin/python -m pytest tests/ -v --tb=short
-```
-
----
-
-## Known Limitations
-
-1. **Model hallucination** - Mistral Nemo sometimes makes up file contents instead of using tool results
-2. **No conversation memory** - CLI chat mode doesn't persist between sessions
-3. **No streaming** - Responses appear all at once
-

+# CLAUDE.md — webber
+
+Local-LLM multi-agent development assistant — "similar to Claude Code but running locally"
+(`webber-api/docs/architecture.md`), backed by Ollama via PydanticAI. Logical monorepo, single
+`.git`, three subprojects: `webber-api/` (FastAPI server, deployed), `webber-cli/` (Typer CLI
+client), `webber-sandbox/` (swappable test project used by `sandbox.sh`, not shipped).
+
+## Ports
+
+| | Port | How |
+|---|---|---|
+| Local dev | **8095** | `cd webber-api && ./wakeup.sh`, uvicorn `--reload`, logs to `webber-api/logs/server.log` |
+| Production | **8086** | container `webber`, confirmed running (`docker ps`) on `docker-dataplane` |
+
+`wakeup.sh` refuses to start if 8095 is already bound — it does not silently pick another
+port. Testing `localhost:8086` on the dev box hits the *container*, not your reload server.
+
+## Live contract
+
+`http://localhost:8086/openapi.json` — 10 paths, `version: 1.0.1` (verified 2026-08-09,
+matches `webber-api/pyproject.toml` and the live `/health` response). Human docs at
+`http://localhost:8086/docs`. Query the live spec rather than inferring routes from source —
+`src/domains/router.py` currently has two routers commented out (see Architecture), so a
+source read alone will overcount if you don't check whether an include is live.
+
+```
+/, /health, /agents/, /agents/run, /agents/stream, /agents/{agent_type},
+/conversations/, /conversations/{conversation_id},
+/conversations/{conversation_id}/messages, /conversations/{conversation_id}/save
+```
+
+## Architecture
+
+Domain-first layout under `webber-api/src/domains/<name>/`. `src/main.py` includes exactly one
+router, `src.domains.router.root_router`, which composes the domain routers. A full directory
+map lives in `webber-api/docs/architecture.md` — read that before adding a domain rather than
+duplicating it here.
+
+**How liveness below was established:** `docker exec webber python3 -c "import src.main; import
+sys; print(sorted(m for m in sys.modules if m.startswith('src.')))"` — i.e. importing the real
+app inside the running container and reading `sys.modules`, not grepping `main.py`. Re-run that
+command to re-check; a grep of imports will miss function-body imports, and this repo has one
+that matters.
+
+- **Wired at startup, serving routes:** `src.domains.health`, `src.domains.agents` (router +
+  `explore`/`plan`/`task` agent packages), `src.domains.conversations`, `src.shared.*`,
+  `src.ollama`, `src.db` (imported both by `conversations/router.py` at module scope and by
+  `main.py`'s lifespan shutdown handler).
+- **Present in source, explicitly disabled:** `src/domains/router.py` has
+  `# from src.domains.auth.router import router as auth_router` and the equivalent for
+  `tools_router` — both commented out with the include calls also commented out. `src/domains/auth/`
+  is just an empty `__init__.py`. This one *is* dead — the disabling is visible in the same file,
+  not a matter of tracing an indirect import.
+- **The trap: `src/domains/tools/` is not in `sys.modules` right after `import src.main`, but it
+  is not dead.** `src/domains/agents/{explore,plan,task}/agent.py` each have a method
+  (e.g. `PlanAgent._register_tools`) that does `from src.domains.agents.plan.tools import
+  register_plan_tools` **inside the function body**, called every time that agent is
+  constructed — i.e. on every `/agents/run` or `/agents/stream` request for that agent type.
+  That nested module then imports the real tool classes from `src.domains.tools.file`,
+  `.search`, `.shell` at module scope. A static snapshot taken before any request is served
+  will not show `src.domains.tools` loaded; that is a timing artifact, not evidence it is
+  unused. Don't delete `src/domains/tools/` on the strength of a `sys.modules` check alone —
+  confirm by hitting `/agents/run` and re-checking, or by tracing the call graph from each
+  agent's `_register_tools`.
+- **`src/cli/`** is the implementation behind `webber-cli`'s `pyproject.toml` script entry —
+  it is a separate Typer app, not imported by the API (`src.main`) at all. Its liveness is
+  "is the CLI installed and invoked", not "is it wired into the API process".
+
+Group new work by domain, not file type — `webber-api/docs/fastapi-best-practices.md` is the
+house reference (mirrors the convention used across the other in-house FastAPI services here).
+
+## Database
+
+SQLite by default (`database_url = "sqlite+aiosqlite:///./webber.db"` in
+`src/shared/config.py`), not Postgres — confirmed by reading `src/shared/config.py` and
+`src/db/database.py` (the latter's docstring says the pattern is ported from core-api, but
+the backend differs). Models under `webber-api/src/domains/<name>/models.py` import `Base`
+from `src/db/models.py`. No Alembic here (unlike core-api) — did not find a migrations
+directory; unverified whether schema changes have any managed migration path at all. Check
+before assuming one exists.
+
+## Working here
+
+**Test locally first.** `cd webber-api && ./wakeup.sh` auto-reloads on code changes (not on
+`requirements.txt` changes — restart after adding a dependency). Deploy only once a feature
+is complete and tested.
+
+```bash
+cd webber-api
+.venv/bin/python -m pytest tests/           # all tests
+.venv/bin/python -m pytest tests/ -v --cov  # verbose + coverage
+.venv/bin/python -m pytest tests/test_tools.py -v   # single file
+```
+
+`webber-api/pyproject.toml` declares `[tool.ruff]` and `[tool.mypy]` — unlike core-api, this
+repo does have ruff/mypy config; whether either runs in CI is a separate question (see CI below
+— it does not).
+
+Copy `webber-api/.env.example` to `webber-api/.env`. Notable defaults: `OLLAMA_URL` points at
+`192.168.86.149:11434` (the host's Ollama, not a container), `OLLAMA_AGENT_MODEL=gemma4:e2b`,
+optional Tatlock integration via `TATLOCK_API_URL`/`INTERNAL_API_KEY`, optional SearXNG via
+`SEARXNG_URL` for the `web_search` tool.
+
+### Sandbox
+
+`webber-sandbox/` is a disposable project used to exercise the agents end-to-end, managed by
+`./sandbox.sh {list,load,reset,save,status}` from the repo root. `sandbox-templates/` holds the
+reusable templates (`calculator-cli` has intentionally-seeded bugs for testing Explore/Task).
+This directory is fixture material, not shipped code — do not treat bugs in it as real bugs.
+
+### CLI
+
+`webber-cli/` is a Typer client (`webber-cli status|chat|explore|sessions|config`) with tab
+completion, session persistence (`~/.webber_history`, `~/.webber/config.toml`), and three chat
+modes (`plan` read-only, `default`, `auto_accept`). It talks to the API over HTTP — it does not
+share a process with `webber-api`. Run it from its own venv: `cd webber-cli && .venv/bin/webber-cli status`.
+
+## CI
+
+`.gitea/workflows/build-api.yml` triggers only on `api/vX.Y.Z` tags: creates a Gitea release,
+builds/pushes `git.schweitz.net/jpmschweitzer/webber-api`, then pings Watchtower.
+`build-cli.yml` triggers on `cli/vX.Y.Z` tags but is a placeholder — it only echoes a TODO, it
+does not build or publish anything. **No test or lint gate runs in CI for either package** —
+pytest and ruff only run locally or on request. Verify tests pass before tagging.
+
+## Work tracking
+
+Work lives in **pql**, not a markdown TODO or `docs/COVERAGE.md`. **This repo's vault is
+standalone** — its tickets and its internal decisions live here in `.pql/` and `governance/`,
+and travel with a clone, because `.pql/changelog/` is committed and replayed by the git hooks
+(workspace D-15). The databases are gitignored and rebuildable with `pql plan rebuild`.
+
+`pql` is **not** on the non-interactive `PATH` — invoke it as
+`/home/jpmschweitzer/.local/bin/pql`. From inside this repo no `--vault` is needed: pql anchors
+at the nearest `.git/` ancestor, which is this repo.
+
+```bash
+/home/jpmschweitzer/.local/bin/pql ticket list        # this repo's open work
+/home/jpmschweitzer/.local/bin/pql plan whatsnext     # next unblocked item, with context
+/home/jpmschweitzer/.local/bin/pql decisions list     # this repo's own decisions
+```
+
+Stack-level decisions that constrain this service live in the **workspace** vault and need the
+flag:
+
+```bash
+/home/jpmschweitzer/.local/bin/pql --vault /mnt/media/Projects decisions list --domain webber
+```
+
+Note `ticket new --decision D-N` resolves ids within **one** vault, so a ticket here cannot link
+to a workspace decision. Cite the id in the ticket body instead.
+
+Do not add a TODO section to a markdown file.
+
+## Git
+
+- **History is linear — no merge commits.** Work on `main`, or a short-lived branch that is
+  fast-forwarded and deleted. (This repo's `AGENTS.md` previously mandated `feature/...` or
+  `fix/...` branches for every change and forbade committing to `main` directly — that rule was
+  retired workspace-wide on 2026-08-08 and does not apply here anymore.)
+- **Conventional Commits**: `feat:`, `fix:`, `refactor:`, `docs:`, `chore:`.
+- **Atomic commits** — one logical change each.
+- **Stage explicitly. Never `git add -A`** — denied by policy; it sweeps in whatever else is
+  dirty, including secrets.
+- Each package versions independently via prefixed tags (`api/vX.Y.Z`, `cli/vX.Y.Z`) and its
+  own `CHANGELOG.md` (`webber-api/CHANGELOG.md`, `webber-cli/CHANGELOG.md`); the root
+  `CHANGELOG.md` is just an index pointing at both.
+
+## Releasing (API)
+
+Ask whether a deploy is wanted first — it is not automatic.
+
+1. Bump the version in `webber-api/pyproject.toml`.
+2. Move `[Unreleased]` entries into a dated version section in `webber-api/CHANGELOG.md`.
+3. Stage the changed files by name, commit, tag `api/vX.Y.Z`, `git push origin main --tags`.
+4. Gitea CI (`build-api.yml`) builds and pushes the image on the tag; Watchtower deploys it.
+5. Verify: `curl http://192.168.86.149:8086/health`.
+
+CLI releases (`cli/vX.Y.Z`) currently only log a TODO in CI — there is no build/publish step
+to trigger yet.
+
+## Known issues (carried over, unverified beyond what's stated)
+
+- **Model hallucination**: the Explore agent's model can hallucinate file contents instead of
+  using actual tool results, per `webber-api/AGENTS.md` — a mitigation (stronger model or
+  response validation) was suggested there but not confirmed implemented.
+- **Ollama `content: null` workaround**: `src/ollama/provider.py` (confirmed present, loaded at
+  startup per the `sys.modules` check above) sanitizes `content: null` to `content: ""` for
+  assistant messages with tool calls, working around an Ollama API limitation.

+# Decisions, Questions, Rejected
+
+This directory holds structured planning records that pql parses
+into pql.db. Each record is a `### [DQR]-N: Title` heading inside
+a markdown file. Files live in three per-type subdirectories:
+
+- `decisions/<domain>.md` — confirmed design decisions
+- `questions/<domain>.md` — open questions that may resolve into
+  decisions or rejected proposals
+- `rejected/<domain>.md` — rejected proposals (kept for the audit
+  trail)
+
+The parser infers domain from the filename stem and record type
+from the parent subdirectory.
+
+D-records that propose implementation work link to `initiative`-type
+tickets via `decision_ref`. Run `pql decisions show <id>
+--with-tickets` to inspect implementation status.
+
+## Recommended domains
+
+Start with this canonical set; create files as records land in
+each domain:
+
+- **architecture** — structural commitments (storage, layering,
+  languages, libraries)
+- **process** — team workflow (commits, branches, releases, reviews)
+- **design** — user-facing surface (UX, UI, public APIs)
+- **coding-conventions** — team-internal code shape (style, lint,
+  file layout)
+- **testing** — quality strategy (coverage, layers, gates)
+
+You might also want, project-permitting:
+
+- `accessibility` — if you ship user-facing software
+- `security` — if you handle user data or network surfaces
+- `licensing` — if you release open-source or commercial
+- `documentation` — if user-docs are non-trivial
+- `deployment` — if shipping is non-trivial
+- `performance` — if you have perf budgets / SLOs
+
+<!-- pql:records (auto-generated; do not edit manually) -->

-# AGENTS.md

-> **Start every session by reading this file.**
-> This file outlines the operational protocols, coding standards, and architectural decisions for this FastAPI project.
-
-## 1. Agent Operational Protocols
-
-### 🧠 Work Patterns (Plan-Act-Reflect)
-* **Plan:** Before writing code, briefly outline your plan. Identify which files you will touch and what the side effects might be.
-* **Act:** Execute the changes in small, atomic steps.
-* **Reflect:** After coding, verify your work. Did you break existing tests? Did you add new tests?
-
-### 🛡️ Git Discipline
-* **ALWAYS add the relevant tests for the added code** Make sure to keep the test coverage up as we go, and run tests before commiting.
-* **NEVER commit to `main` or `master` directly.** Always create a feature branch: `feature/your-feature-name` or `fix/issue-description`.
-* **Commit Messages:** Use the [Conventional Commits](https://www.conventionalcommits.org/) format.
-    * `feat: add user login endpoint`
-    * `fix: resolve database connection timeout`
-    * `refactor: split monolith dependency file`
-* **Atomic Commits:** Keep commits small. One logical change = one commit.
-
-### 📝 Changelog Maintenance
-* **Update `CHANGELOG.md`** with every user-facing change.
-* Format: `## [Unreleased] - YYYY-MM-DD` followed by `### Added`, `### Changed`, or `### Fixed`.
-
-### 🚀 Release Flow
-When changes are ready for deployment:
-
-1. **Ask user if deploy cycle is desired **
-
-2. **Update version** in `pyproject.toml`:
-   - Bug fixes: bump patch version (1.8.3 → 1.8.4)
-   - New features: bump minor version (1.8.4 → 1.9.0)
-
-3. **Update CHANGELOG.md**:
-   - Move items from `[Unreleased]` to new version section
-   - Add release date: `## [1.8.4] - 2025-12-16`
-
-4. **Commit and tag**:
-   ```bash
-   git add -A
-   git commit -m "fix: description of changes"
-   git tag v1.8.4
-   git push origin main --tags
-   ```
-
-5. **CI/CD triggers automatically**:
-   - Gitea CI builds Docker image on new version tag (starts with "v")
-   - Watchtower pulls and deploys to production
-   - Verify deployment: `curl http://192.168.86.149:8086/health`
-
----
-
-### 🧪 Local Development Setup
-
-* **Always test locally first** before committing and deploying. The build-deploy loop is slow.
-* **Only deploy** when a phase or feature is complete and tested locally
-* **Environment**: Copy `.env.example` to `.env` and configure for your local setup
-
-#### ⚠️ CRITICAL: Starting the Local Server
-
-**ALWAYS use `./wakeup.sh` to start the local server. NEVER use raw uvicorn commands.**
-
-```bash
-./wakeup.sh
-```
-
-The wakeup script provides:
-- **Port conflict detection** - Warns if port 8086 is already in use
-- **Virtual environment activation** - Ensures correct Python environment
-- **Centralized logging** - All logs written to `logs/server.log` for easy tailing
-- **Auto-reload** - Code changes picked up automatically (except requirements.txt changes)
-- **Consistent configuration** - Same startup every time
-
-To monitor logs in another terminal:
-```bash
-tail -f logs/server.log
-```
-
-To stop the server: Press `Ctrl+C`
-
-To kill a stuck server:
-```bash
-pkill -f "uvicorn src.main:app"
-# or
-kill $(lsof -t -i:8086)
-```
-
-#### Testing
-
-**Test REST endpoints** against `http://localhost:8086`:
-```bash
-curl http://localhost:8086/health
-curl http://localhost:8086/
-curl http://localhost:8086/docs   # Swagger UI
-```
-
-**Running tests**: Always use the venv explicitly to avoid environment mismatches:
-```bash
-.venv/bin/python -m pytest tests/           # All tests
-.venv/bin/python -m pytest tests/ -v        # Verbose output
-.venv/bin/python -m pytest tests/ --cov     # With coverage
-```
-

-## 1.5 Known Issues & Future Improvements
-
-### Explore Agent
-
-- **Model Hallucination**: Mistral Nemo sometimes hallucinates file contents instead of using actual tool results. Consider using a more capable model (codestral, qwen2.5-coder) or adding response validation.
-
-- **Ollama Provider**: We use a custom `WebberOllamaProvider` (ported from tatlock) that sanitizes `content: null` to `content: ""` for assistant messages with tool calls. This works around an Ollama API limitation.
-
-- **Gitignore Support**: ✅ Fixed - The filesystem tools now honor `.gitignore` patterns and default ignores (`.venv/`, `__pycache__/`, `node_modules/`, etc.).

-## 2. FastAPI Architecture & Best Practices
-*Reference: [FastAPI Best Practices](https://github.com/zhanymkanov/fastapi-best-practices)*
-
-### 📂 Project Structure (Directory-based, NOT File-type based)
-Do **not** group files by type (e.g., one huge `routers` folder). Group by **domain/module** inside a `src/` directory.

+# Changelog - Webber API
+
+All notable changes to the Webber API will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+## [1.1.0] - 2026-08-11
+
+### Added
+- `webber version` command. It was implemented and imported but never registered, so the
+  subcommand did not exist; the fuller output includes the resolved Ollama URL and model.
+
+### Fixed
+- The Ollama `content: null` sanitiser raised `AttributeError` on first use. It looked up the
+  parent client's chat getter via `.fget`, and openai now exposes `chat` as a
+  `cached_property`. Any agent request would have failed before reaching the model.
+
+### Changed
+- Default `OLLAMA_AGENT_MODEL` is now `gemma4:e2b` instead of `mistral-nemo-large:latest`, so a deployment without an explicit override no longer exhausts shared GPU memory
+- `BaseAgent` is generic over its context type and `run_stream` is typed as
+  `AsyncIterator[str | StreamEvent]`, matching what callers already receive.
+
+## [1.0.1] - 2026-07-19
+
+### Changed
+- Default `TATLOCK_API_URL` and `SEARXNG_URL` now use docker container names (`http://tatlock:8000`, `http://searxng:8080`) instead of host IP:port, for container-to-container traffic on the docker-dataplane network
+- CI workflow now pushes Docker images via the `git.schweitz.net` registry route
+
+## [1.0.0] - 2026-01-15
+
+### Added
+- Event-based streaming for task agent (`StreamEvent` objects instead of raw text)
+  - New `tools_streaming.py` with all tools emitting structured events
+  - Event types: `tool_start`, `tool_done`, `thinking`, `response`, `error`, `done`
+- Retry logic when LLM responds without calling tools (max 2 retries)
+  - Tracks `tools_called` counter on TaskContext
+  - Stronger retry prompt forces tool use
+- Working directory context injected into all agent prompts
+
+### Changed
+- Hardened system prompts to enforce tool use before responding
+  - Added "CRITICAL RULE" section requiring tool calls first
+  - Made "MANDATORY WORKFLOW" more emphatic
+- Updated explore and plan agents with `_build_prompt_with_context()` method
+
+### Fixed
+- Agent path hallucination - now explicitly communicates working directory to LLM
+
+### Note
+- Project paused: Local LLMs (Mistral Nemo 12B on available hardware) are not capable enough for reliable agentic tool use. Models frequently hallucinate responses instead of calling tools, even with prompt hardening and retry logic. Would require larger models (70B+) or cloud API integration to continue.
+
+## [0.4.2] - 2026-01-11
+
+### Added
+- Retry logic for transient failures with exponential backoff
+  - `src/shared/retry.py` - `@with_retry` decorator and `retry_async()` function
+  - Retries on: timeout, connection errors, HTTP 429/5xx
+  - Configurable: `RETRY_MAX_ATTEMPTS`, `RETRY_BASE_DELAY`, `RETRY_MAX_DELAY`
+- Web search tool now automatically retries on network failures
+- 29 retry tests (205 total tests passing)
+
+## [0.4.1] - 2026-01-11
+
+### Fixed
+- Replace `litellm` with `tiktoken` for token counting (dependency conflict with pydantic-ai)
+- Update documentation (README.md, architecture.md) with conversation layer info
+
+## [0.4.0] - 2026-01-11
+
+### Added
+- Conversation persistence layer with SQLAlchemy async
+  - Database models: `Conversation`, `Message` with UUID primary keys
+  - SQLite (dev) and PostgreSQL (prod) support via async engines
+  - Lazy database initialization pattern
+- Context management infrastructure
+  - Token counting utilities using `tiktoken`
+  - Context summarization at 80% token threshold
+  - XML-tagged context prompt building for agent injection
+- REST API for multi-turn conversations
+  - `POST /conversations/` - Create new conversation
+  - `GET /conversations/` - List conversations
+  - `GET /conversations/{id}` - Get conversation with history
+  - `POST /conversations/{id}/messages` - Add message (triggers agent)
+  - `DELETE /conversations/{id}` - Delete conversation
+- New dependencies: `sqlalchemy[asyncio]~=2.0.36`, `aiosqlite~=0.21.0`, `tiktoken>=0.12.0`
+- Config settings: `database_url`, `summarization_threshold`, `keep_recent_messages`
+- 19 conversation tests, 6 token counting tests (176 total tests passing)
+
+### Changed
+- Updated COVERAGE.md to ~80% complete
+- Quieter pytest output (`-q --tb=short` instead of `-v`)
+
+## [0.3.4] - 2026-01-11
+
+### Added
+- Task Agent - Full orchestrator for autonomous multi-step task execution
+  - Has ALL tools: read, write, edit, bash (full), web_search

+- Complete agent hierarchy: Explore (read-only) → Plan (read-only) → Task (orchestrator)
+
+## [0.3.3] - 2026-01-11
+
+### Added
+- Plan Agent - READ-ONLY software architect that designs implementation strategies
+  - Uses only read-only tools: `read_file`, `glob_files`, `grep_content`, `bash_readonly`
+  - Creates step-by-step implementation plans with critical files list
+  - 15 unit tests for registration, tools, and API
+- Web search summarizer added to roadmap (future feature)
+
+### Changed
+- Updated COVERAGE.md to ~70% complete

+| Monorepo structure | `webber-api/`, `webber-cli/` | Separate packages, shared root |
 | Sanitized Ollama provider | Custom wrapper | Fixes PydanticAI + Ollama `content: null` bug |

+## Database Layer
+
+SQLAlchemy 2.0 async with lazy initialization pattern.
+
+### Supported Databases
+- **Development**: SQLite via `aiosqlite`
+- **Production**: PostgreSQL via `asyncpg`
+
+### Pattern
+```python
+from src.db import get_session
+from sqlalchemy.ext.asyncio import AsyncSession
+
+async def my_endpoint(session: AsyncSession = Depends(get_session)):
+    # Session auto-commits on success, rollbacks on exception
+    result = await session.execute(query)
+```
+
+Tables are created lazily on first `get_session()` call.
+
+---
+
+## Conversation API
+
+Multi-turn conversation memory with automatic context summarization.
+
+### Endpoints
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `/conversations/` | POST | Create new conversation |
+| `/conversations/` | GET | List user's conversations |
+| `/conversations/{id}` | GET | Get conversation with history |
+| `/conversations/{id}/messages` | POST | Add message, triggers agent |
+| `/conversations/{id}` | DELETE | Delete conversation |
+
+### Models
+- **Conversation**: User session with agent type, working directory
+- **Message**: Individual messages with role, content, token count
+
+### Context Summarization
+When total tokens exceed 80% of `MAX_CONTEXT_TOKENS`:
+1. Keep last 6 messages intact
+2. Summarize older messages into a single summary message
+3. Mark old messages as summarized (soft delete)

+- glob_files: Find files by pattern
+- read_file: Read file contents
+- grep_content: Search code with regex
+- bash_readonly: Run read-only commands (ls, git status, git log, etc.)

+3. Design an implementation approach
+4. Create a step-by-step plan with specific files and changes

+  Call glob_files with pattern="**/*.py"
+
+To find a specific file:
+  Call glob_files with pattern="**/config.py"
+
+To read a file:

+
+You can explore and analyze code but CANNOT modify files or execute write operations.

+- Use spawn_agent to offload focused tasks to specialized agents
+- Explore agent: Fast codebase searches and analysis
+- Plan agent: Design implementation strategies
+- Keep each agent's context focused and efficient
