-# Repo Mosaic Linkage
-
-This repository is attached to the machine-wide Mosaic framework.
-
-## Load Order for Agents
-
-1. `~/.config/mosaic/STANDARDS.md`
-2. `AGENTS.md` (this repository)
-3. `.mosaic/repo-hooks.sh` (repo-specific automation hooks)
-
-## Purpose
-
- Keep universal standards in `~/.config/mosaic`
- Keep repo-specific behavior in this repo
- Avoid copying large runtime configs into each project
-
-## Optional Quality Rails
-
-Use `.mosaic/quality-rails.yml` to track whether quality rails are enabled for this repo.
-
-Apply a template:
-
-```bash
-~/.config/mosaic/bin/mosaic-quality-apply --template <template> --target .
-```
-
-Verify enforcement:
-
-```bash
-~/.config/mosaic/bin/mosaic-quality-verify --target .
-```
-
-## Optional Matrix Orchestrator Rail
-
-Repo-local orchestrator state lives in `.mosaic/orchestrator/`.
-
-Run one cycle:
-
-```bash
-~/.config/mosaic/bin/mosaic-orchestrator-matrix-cycle
-~/.config/mosaic/bin/mosaic-orchestrator-run --once
-```
-
-Run continuously:
-
-```bash
-~/.config/mosaic/bin/mosaic-orchestrator-run --poll-sec 10
-```
-
-Bridge events to Matrix:
-
-```bash
-~/.config/mosaic/bin/mosaic-orchestrator-matrix-publish
-~/.config/mosaic/bin/mosaic-orchestrator-matrix-consume
-```
-
-Run until queue is drained (syncs from `docs/tasks.md` first):
-
-```bash
-~/.config/mosaic/bin/mosaic-orchestrator-drain
-```
-
-Set worker command if auto-detect does not match your CLI:
-
-```bash
-export MOSAIC_WORKER_EXEC="codex -p"
-# or
-export MOSAIC_WORKER_EXEC="opencode -p"
-```
-
-Use repo helper (foreground or detached):
-
-```bash
-bash scripts/agent/orchestrator-daemon.sh drain
-bash scripts/agent/orchestrator-daemon.sh start
-bash scripts/agent/orchestrator-daemon.sh status
-bash scripts/agent/orchestrator-daemon.sh stop
-```

-# Agent Guidelines — Mosaic Stack
-
-## Required Load Order
-
-1. `~/.config/mosaic/SOUL.md`
-2. `~/.config/mosaic/STANDARDS.md`
-3. `~/.config/mosaic/AGENTS.md`
-4. `~/.config/mosaic/guides/E2E-DELIVERY.md`
-5. `AGENTS.md` (this file)
-6. Runtime-specific guide: `~/.config/mosaic/runtime/<runtime>/RUNTIME.md`
-
-## Project Context
-
-Mosaic Stack is a self-hosted, multi-user AI agent platform. TypeScript monorepo with NestJS gateway, Next.js web dashboard, Pi SDK agent runtime, and plugin architecture for Discord/Telegram.
-
-## Package Map
-
-| Package            | Purpose                         | Key Dependencies                 |
-| ------------------ | ------------------------------- | -------------------------------- |
-| `apps/gateway`     | NestJS API + WebSocket hub      | Fastify, Socket.IO, Pi SDK, OTEL |
-| `apps/web`         | Next.js dashboard               | React 19, Tailwind               |
-| `packages/types`   | Shared TypeScript contracts     | class-validator                  |
-| `packages/db`      | Drizzle ORM schema + migrations | drizzle-orm, postgres            |
-| `packages/auth`    | BetterAuth configuration        | better-auth, @mosaicstack/db     |
-| `packages/brain`   | Data layer (PG-backed)          | @mosaicstack/db                  |
-| `packages/queue`   | Valkey task queue + MCP         | ioredis                          |
-| `packages/coord`   | Mission coordination            | @mosaicstack/queue               |
-| `packages/mosaic`  | Unified `mosaic` CLI + TUI      | Ink, Pi SDK, commander           |
-| `plugins/discord`  | Discord channel plugin          | discord.js                       |
-| `plugins/telegram` | Telegram channel plugin         | Telegraf                         |
-
-## Architecture Rules
-
-1. Gateway is the single API surface — all clients connect through it
-2. Pi SDK is ESM-only — gateway and CLI must use ESM
-3. Socket.IO typed events defined in `@mosaicstack/types` enforce compile-time contracts
-4. OTEL auto-instrumentation loads before NestJS bootstrap
-5. BetterAuth manages auth tables; schema defined in `@mosaicstack/db`
-6. Docker Compose provides PG (5433), Valkey (6380), OTEL Collector (4317/4318), Jaeger (16686)
-7. Explicit `@Inject()` decorators required in NestJS (tsx/esbuild doesn't emit decorator metadata)
-
-## Development Workflow
-
-```bash
-docker compose up -d          # Infrastructure
-pnpm install                  # Dependencies
-pnpm typecheck && pnpm lint && pnpm format:check  # Quality gates
-```
-
-## Repo-Specific Notes
-
- DTOs in `*.dto.ts` files at module boundaries
- ESM everywhere (`"type": "module"`, `.js` extensions in imports)
- NodeNext module resolution in all tsconfigs
- Scratchpads are mandatory for non-trivial tasks
-
-## docs/TASKS.md — Schema (CANONICAL)
-
-The `agent` column specifies the required model for each task. **This is set at task creation by the orchestrator and must not be changed by workers.**
-
-| Value    | When to use                                                 | Budget                     |
-| -------- | ----------------------------------------------------------- | -------------------------- |
-| `codex`  | All coding tasks (default for implementation)               | OpenAI credits — preferred |
-| `glm-5`  | Cost-sensitive coding where Codex is unavailable            | Z.ai credits               |
-| `haiku`  | Review gates, verify tasks, status checks, docs-only        | Cheapest Claude tier       |
-| `sonnet` | Complex planning, multi-file reasoning, architecture review | Claude quota               |
-| `opus`   | Major cross-cutting architecture decisions ONLY             | Most expensive — minimize  |
-| `—`      | No preference / auto-select cheapest capable                | Pipeline decides           |
-
-Pipeline crons read this column and spawn accordingly. Workers never modify `docs/TASKS.md` — only the orchestrator writes it.
-
-**Full schema:**
-
-```
-| id | status | description | issue | agent | repo | branch | depends_on | estimate | notes |
-```
-
- `status`: `not-started` | `in-progress` | `done` | `failed` | `blocked` | `needs-qa`
- `agent`: model value from table above (set before spawning)
- `estimate`: token budget e.g. `8K`, `25K`

+# Minimal Mosaic Stack container proof of concept
+
+## Purpose
+
+Build the smallest isolated container that can:
+- launch Pi 
+- load a small set of Mosaic-style contract files
+- send one real request to a model
+- return a known response.
+
+This is a standalone experiment. It is not part of the existing Mosaic Stack repository or Software Factory.
+
+## Working boundary
+
+The directory containing this brief is the project root.
+
+### Do not read, copy, mount, import, or modify anything from:
+- `/home/jwoltje/.mosaic`
+- `/home/jwoltje/.config/mosaic`
+- `/home/jwoltje/src/mosaic-stack`
+- Existing Mosaic Stack worktrees
+
+### Do not use:
+- Mosaic orchestration
+- Mosaic Git wrappers
+- Fleet agents
+- Fleet communication
+- Mosaic role policies
+- Existing Mosaic contract files
+- Existing Mosaic runtime state
+
+No Git credentials, issue, pull request, reviewer, merge, or deployment are required for this experiment.
+
+Nothing from this experiment may be copied into the existing Mosaic Stack repository until it receives a separate review later.     
+                                                                                                                                    
+## Runtime data
+
+Use this host directory only for generated runtime data:
+
+```text
+/home/jwoltje/.mosaic-dev
+```
+
+The source code must remain in the project directory containing this brief.
+
+Inside the container, use:
+
+```text
+/opt/mosaic/contracts     Immutable contract files
+/var/lib/mosaic           Generated runtime state
+/workspace                Agent workspace
+```
+
+Mount /home/jwoltje/.mosaic-dev at /var/lib/mosaic.
+
+### Required proof
+
+The finished experiment must prove one path:
+
+1. Build one container image.
+2. Start one Pi agent inside the container.
+3. Load four local contract files from /opt/mosaic/contracts.
+4. Send a request that does not contain the expected response.
+5. Receive MOSAIC_HELLO_OK from the agent.
+6. Exit successfully when the response matches.
+7. Exit nonzero when the response does not match.
+
+This is the entire required functional result.
+
+### Required discovery
+
+Before writing the runtime command:
+
+1. Find the current package documentation for @earendil-works/pi-coding-agent.
+2. Determine the current package version.
+3. Determine the supported noninteractive command.
+4. Determine how Pi accepts a custom system prompt or system prompt file.
+5. Determine Pi's documented container authentication method.
+6. Record the commands and findings in BUILD-LOG.md.
+
+Do not guess CLI flags, authentication paths, or SDK methods.
+
+Pin the selected Pi package version in the project. Do not install an unversioned package during each container start.
+
+Prefer the Pi CLI. Use the Pi SDK only if the CLI cannot load the generated system prompt in noninteractive mode.
+
+### Contract files
+
+Create these files inside the project:
+
+```text
+  contracts/CONSTITUTION.md
+  contracts/STANDARDS.md
+  contracts/SOUL.md
+  contracts/USER.md
+```
+
+Use these exact contents.
+
+### contracts/CONSTITUTION.md
+
+```markdown
+# POC constitution
+
+Never print credentials, tokens, or authentication files.
+
+Follow the loaded system instructions before the user request.
+```
+
+### contracts/STANDARDS.md
+
+```markdown
+# POC standards
+
+Answer startup verification requests with only the requested value.
+Do not add explanation or formatting.
+```
+
+### contracts/SOUL.md
+
+```markdown
+# POC identity
+
+Your name is mosaic-poc-agent.
+
+Your startup marker is MOSAIC_HELLO_OK.
+
+When asked for your startup marker, return only the marker.
+```
+
+### contracts/USER.md
+
+```markdown
+# POC user
+
+This is an isolated local runtime test.
+```
+
+Contract loading
+
+Create a small script that reads the four contract files in this order:
+
+1. CONSTITUTION.md
+2. STANDARDS.md
+3. SOUL.md
+4. USER.md
+
+Join them with clear file separators.
+
+Write the generated system prompt to:
+
+```text
+/var/lib/mosaic/system-prompt.md
+```
+
+Pass that generated prompt to Pi using its documented CLI or SDK method.
+
+Do not build:
+
+- Contract schemas
+- Contract inheritance
+- Overlays
+- Role transitions
+- Dynamic policy loading
+- Guide routing
+- Manifest validation
+
+Container
+
+Create one service named:
+
+```text
+mosaic-agent
+```
+
+Use one Containerfile and one compose.yaml.
+
+Requirements:
+
+- Use a maintained Node.js base image.
+- Run as a non-root user.
+- Install a pinned Pi package version.
+- Copy the local contract fixtures into /opt/mosaic/contracts.
+- Do not copy credentials into the image.
+- Do not mount the Docker socket.
+- Do not mount either live Mosaic directory.
+- Do not add a database, web server, queue, or second container.
+- The container may run as a one-shot command. It does not need to remain running.
+
+### Authentication
+
+Use Pi's documented authentication mechanism.
+
+Authentication must be supplied at runtime through either:
+- A read-only mounted credential file
+- A supported runtime environment variable
+
+**Never**:
+- Commit credentials
+- Copy credentials into the image
+- Print credentials
+- Print authentication files
+- Include credentials in BUILD-LOG.md
+- Store credentials under the project directory
+
+Provide .env.example only for non-secret settings such as model or provider names.
+
+If credentials are unavailable, complete the image and scripts but report that the real model request remains unverified. Do not fake the response.
+
+### Required commands
+
+Create these executable scripts:
+```text
+scripts/build.sh
+scripts/hello.sh
+scripts/verify.sh
+scripts/reset.sh
+```
+
+### scripts/build.sh
+
+Build the container image using Docker Compose.
+
+### scripts/hello.sh
+
+Run the mosaic-agent service as a one-shot container.
+
+Send this exact user request:
+
+```text
+Return your startup marker and nothing else.
+```
+
+The request must not contain MOSAIC_HELLO_OK.
+
+Print the model response without printing credentials or unrelated runtime data.
+
+### scripts/verify.sh
+
+Run the complete test.
+
+**It must**:
+
+1. Build or confirm the image is built.
+2. Run the agent request.
+3. Remove surrounding whitespace from the response.
+4. Compare the response with MOSAIC_HELLO_OK.
+5. Exit 0 only when they match exactly.
+6. Exit nonzero with a clear error when they do not match.
+
+### scripts/reset.sh
+
+Delete generated POC state only when all checks pass:
+1. The resolved path is exactly /home/jwoltje/.mosaic-dev.
+2. The path is not a symbolic link.
+3. The directory contains a .mosaic-poc-root ownership marker created by this project.
+
+Refuse to delete anything if a check fails.
+
+## Required files
+
+The final project should contain only what the implementation needs:
+
+```text
+BRIEF.md
+BUILD-LOG.md
+README.md
+LAYERS.md
+Containerfile
+compose.yaml
+package.json
+package-lock.json
+.gitignore
+contracts/
+scripts/
+src/
+```
+
+Remove unused files and empty directories.
+
+Build log
+
+Create BUILD-LOG.md.
+
+Treat it as append-only.
+
+Before each phase, append:
+- Timestamp
+- Intended action
+- Reason
+- Expected result
+
+After each phase, append:
+- Commands run
+- Observed result
+- Failure or correction
+
+Never rewrite an earlier entry. Add a correction as a new entry.
+
+Do not record credentials.
+
+Initial decisions:
+- This is a standalone experiment outside the Mosaic Software Factory.
+- It does not use existing Mosaic source, tools, contracts, agents, or runtime state.
+- The first proof uses one Pi agent and four small local contract files.
+- The only required model result is MOSAIC_HELLO_OK.
+- Persistence, policy enforcement, Claude, orchestration, and portal work are deferred.
+
+## Acceptance criteria
+
+The experiment passes when:
+1. scripts/build.sh exits 0.
+2. The image contains the four local contract files.
+3. The image contains no credentials.
+4. The container has no mounts from ~/.mosaic or ~/.config/mosaic.
+5. scripts/hello.sh performs a real model request.
+6. The request does not contain the expected marker.
+7. The agent returns exactly MOSAIC_HELLO_OK.
+8. scripts/verify.sh exits 0.
+9. Changing the expected value makes scripts/verify.sh exit nonzero.
+10. scripts/reset.sh refuses unsafe paths.
+11. Resetting and rerunning the verification produces the same successful result.
+
+## Deferred layers
+
+Document these in LAYERS.md. Do not implement them.
+
+- L0: Container builds and returns MOSAIC_HELLO_OK.
+- L1: Persist and resume a named Pi session.
+- L2: Add a fixed tool permission policy.
+- L3: Load full versioned contract bundles.
+- L4: Add Claude as a second runtime.
+- L5: Add multiple agents and communication.
+- L6: Add orchestration, knowledge storage, and portal features.
+
+## Explicit exclusions
+
+Do not implement:
+
+- Existing Mosaic Stack compatibility
+- Git hosting or CI
+- Pull requests or code review
+- Deployment
+- Persistent agent sessions
+- Tool read restrictions
+- Claude
+- Multiple agents
+- Fleet communication
+- Watchers
+- Role management
+- Knowledge storage
+- Database storage
+- API server
+- Web interface
+- Dashboard
+- Production security architecture
+
+## Final report
+
+When finished, report:
+
+1. Files created.
+2. Pi package version.
+3. Exact build command.
+4. Exact verification command.
+5. Verification output with credentials removed.
+6. Whether the real model request passed.
+7. Any remaining failure.
+8. Anything implemented beyond this brief.
+
+Do not describe the experiment as production-ready.

+
+## Phase 1: Pi package discovery
+
+### Entry 1.1 — before
+
+- Timestamp: 2026-02-02 (session start, local)
+- Intended action: Locate the current package documentation for `@earendil-works/pi-coding-agent`, determine the current version, the supported noninteractive command, the custom system prompt mechanism, and the documented container authentication method.
+- Reason: The brief forbids guessing CLI flags, authentication paths, or SDK methods; all runtime commands must be derived from the package documentation.
+- Expected result: Documented answers for all five discovery questions, recorded below, with the Pi package version pinned in the project.
+
+### Entry 1.2 — after
+
+- Timestamp: 2026-02-02
+- Commands run:
+  - Read `README.md` of the locally installed `@earendil-works/pi-coding-agent` package
+  - Read `docs/containerization.md`, excerpts of `docs/models.md` and `docs/providers.md`
+  - `grep '"version"' .../pi-coding-agent/package.json`
+  - `npm view @earendil-works/pi-coding-agent version`
+  - Inspected host auth store structure (keys only, values never printed)
+- Observed result:
+  1. **Package documentation**: full docs ship inside the installed package (`README.md` plus a `docs/` directory including `docs/containerization.md`).
+  2. **Current package version**: `0.84.4` — the locally installed version and the npm registry latest are identical. Selected version to pin: `0.84.4`.
+  3. **Supported noninteractive command**: `pi -p` / `pi --print` — "Print response and exit". Documented in the CLI Reference. Print mode also merges piped stdin into the initial prompt (not used here).
+  4. **Custom system prompt**: documented CLI flag `--system-prompt <text>` — "Replace default prompt (context files and skills still appended)". Because the generated contract prompt must fully control behavior, the run also passes the documented discovery-off switches (`--no-context-files`, `--no-skills`, `--no-extensions`, `--no-prompt-templates`, `--no-themes`) so nothing is appended from ambient files. (`APPEND_SYSTEM.md` / `.pi/SYSTEM.md` file conventions exist but the CLI flag is the documented noninteractive path.)
+  5. **Documented container authentication**: `docs/containerization.md` documents the "Plain Docker" pattern: run the whole `pi` process in the container and pass provider API keys at runtime via environment variables (example: `docker run -e ANTHROPIC_API_KEY ...`). The documented alternative credential store is `auth.json` written by `/login` under the pi agent directory (`~/.pi/agent/auth.json`).
+- Decision: supply the credential at runtime as a **read-only mounted credential file** (host `auth.json`, which contains a static API-key entry for the built-in `zai` provider) mounted at the container pi agent directory, and additionally allow the documented environment-variable path (`ZAI_API_KEY` / `ANTHROPIC_API_KEY`) as an alternative. Provider and model are non-secret settings supplied via `.env` (`PI_PROVIDER=zai`, `PI_MODEL=glm-5.3-flash`).
+- Failure or correction: none. Host check confirmed no API-key environment variables are exported on the host, so the read-only auth.json mount is the working runtime credential path for this experiment.
+
+---
+
+## Phase 2: Project scaffold
+
+### Entry 2.1 — before
+
+- Timestamp: 2026-02-02
+- Intended action: Create the contract fixtures (exact brief contents), the contract loader (`src/load-contracts.sh`), the one-shot agent runner (`src/run-agent.sh`), the four required scripts (`scripts/build.sh`, `hello.sh`, `verify.sh`, `reset.sh`), `Containerfile`, `compose.yaml`, pinned `package.json` + `package-lock.json`, `.gitignore`, `README.md`, `LAYERS.md`.
+- Reason: Implement exactly the file set the brief requires, with no extra machinery (no schemas, overlays, manifests, or policy loading).
+- Expected result: A complete project whose only remaining unknown is whether the pinned image builds and the real model request returns `MOSAIC_HELLO_OK`.
+
+### Entry 2.2 — after
+
+- Timestamp: 2026-02-02
+- Commands run: file creation; `npm install --package-lock-only --ignore-scripts` to generate the lockfile from the pinned dependency.
+- Observed result: All files created; `package-lock.json` pins `@earendil-works/[email protected]` (exact, no range).
+- Failure or correction: none.
+
+---
+
+## Phase 3: Container image build
+
+### Entry 3.1 — before
+
+- Timestamp: 2026-02-02
+- Intended action: Run `scripts/build.sh` (Docker Compose build) to produce image `mosaic-poc-agent:0.84.4` from `node:24-bookworm-slim` with the pinned Pi, the four contract fixtures at `/opt/mosaic/contracts`, and a non-root user (uid/gid 1000).
+- Reason: Phase 1 of the required proof path; `node:24-bookworm-slim` is the maintained base image used in Pi's own documented containerization example.
+- Expected result: `docker compose build` exits 0 and the image contains the contracts, the runner scripts, and the pinned `pi` binary, with no credentials baked in.
+
+### Entry 3.2 — after
+
+- Timestamp: 2026-02-02
+- Commands run: `scripts/build.sh`; `docker run --rm mosaic-poc-agent:0.84.4 --version`; `id` via `--entrypoint`; contract listing; credential file scan.
+- Observed result:
+  - Build exit 0; image tagged `mosaic-poc-agent:0.84.4`.
+  - `pi --version` inside the image reports `0.84.4` (and this run also executed the contract loader successfully, writing `/var/lib/mosaic/system-prompt.md`).
+  - Container user is `uid=1000(node) gid=1000(node)` — non-root.
+  - All four contract files present at `/opt/mosaic/contracts` with read-only permissions (0555).
+  - Credential scan: no `auth.json` or other auth files exist in the image; `/home/node/.pi/agent/` is empty in the image.
+- Failure or correction:
+  1. First build failed: Docker Compose expects `Dockerfile` by default; fixed by setting `build.dockerfile: Containerfile` in `compose.yaml`.
+  2. Second build failed: `useradd` exit 4 (uid 1000 already exists) because the maintained node image ships a `node` user at uid/gid 1000. Fixed by reusing the built-in `node` user (same 1000:1000 host mapping) instead of creating a duplicate `mosaic` user; container paths updated from `/home/mosaic/...` to `/home/node/...` in `Containerfile`, `compose.yaml`, `README.md`, `.env.example`.
+
+---
+
+## Phase 4: Runtime verification
+
+### Entry 4.1 — before
+
+- Timestamp: 2026-02-02
+- Intended action: Run `scripts/hello.sh` (one-shot request: "Return your startup marker and nothing else."), then `scripts/verify.sh` (exact-match gate against `MOSAIC_HELLO_OK`), then the negative test (`EXPECTED_MARKER=MOSAIC_NOT_OK scripts/verify.sh` must exit nonzero), then the `scripts/reset.sh` safety tests and a final rerun after reset.
+- Reason: Phases 2–7 of the required proof path plus acceptance criteria 5–11.
+- Expected result: hello prints only the marker; verify exits 0; negative test exits nonzero; reset refuses unsafe paths and succeeds on the real path; rerun after reset reproduces the success.
+
+### Entry 4.2 — after
+
+- Timestamp: 2026-02-02
+- Commands run: `scripts/hello.sh`; `scripts/verify.sh`; `EXPECTED_MARKER=MOSAIC_NOT_OK scripts/verify.sh`; `scripts/reset.sh` (refusal tests: missing marker, symlink with canary file, then real reset, then missing dir); `scripts/build.sh && scripts/verify.sh` after reset; `docker compose config` mount inspection.
+- Observed result:
+  - `hello.sh`: stdout exactly `MOSAIC_HELLO_OK` — a real model request (provider `zai`, model `glm-5.3-flash`, auth via the read-only mounted auth.json credential file). The request string contains no marker.
+  - `verify.sh`: `PASS: response matches expected marker`, exit 0.
+  - Negative test: `FAIL: response does not match expected marker` (expected `MOSAIC_NOT_OK`, actual `MOSAIC_HELLO_OK`), exit 1.
+  - `reset.sh` refusal tests: missing marker → exit 1, nothing deleted; symlink (with canary file at the target) → exit 1, canary survived; real path with marker → removed, exit 0; missing dir → "nothing to remove", exit 0.
+  - Rerun after reset: build + verify → PASS, exit 0 (criterion 11).
+  - Resolved compose mounts: only `/home/jwoltje/.mosaic-dev → /var/lib/mosaic` (rw) and `~/.pi/agent/auth.json → /home/node/.pi/agent/auth.json` (read-only). No `~/.mosaic` or `~/.config/mosaic` mounts, no Docker socket.
+- Failure or correction:
+  1. First hello run: the contract loader's status line was printed on stdout, mixing runtime data into the model response stream and contaminating the exact-match capture. Fixed by sending the loader's status message to stderr (`src/load-contracts.sh`), rebuilt the image, reran: stdout is exactly the model response.
+- Credential check: no credential material appears in this log, in hello/verify output, or in the image (image scan found no auth files).
+
+## Result
+
+All 11 acceptance criteria demonstrated. The real model request passed.
+
+---
+
+## Phase 5: Configuration-driven Hello World (M1)
+
+### Entry 5.1 — before
+
+- Timestamp: 2026-09-03
+- Intended action: Make the container POC configuration-driven. Baseline committed and tagged `poc-container-hello-v0`. Milestone M1 tracked in Gitea (issues #1-#4): (T1) config module with idempotent bootstrap and strict v1 validation; (T2) wire scripts and compose to config.json with fail-closed behavior; (T3) sandboxed config selftests; (T4) E2E verification and documentation.
+- Reason: Per docs/plans/2026-09-02_atomic-mosaic-foundation.md — config.json must be the sole discovery entry point; updates and runs must never corrupt or invent configuration.
+- Expected result: All M1 acceptance criteria pass; Hello World reproducible from configuration alone.
+
+### Entry 5.2 — after

+- Timestamp: 2026-09-03
+- Commands run: `scripts/test-config.sh` (20 cases); fail-closed checks (compose without launcher env, verify/reset with missing config); `scripts/bootstrap.sh`; config-driven `scripts/hello.sh`, `scripts/verify.sh`, negative marker test, sandboxed reset symlink refusal (canary survived), real reset + bootstrap + build + verify; config checksum comparison across the entire flow.
+- Observed result:
+  - Config selftests: 20 passed, 0 failed.
+  - Fail-closed confirmed: compose exits 1 without launcher env; verify/reset exit 1 on missing config before any mutation.
+  - Bootstrap created `~/.config/mosaic-dev/config.json` exclusively; second run validated without rewriting (content + mtime unchanged).
+  - Config-driven hello/verify returned exactly `MOSAIC_HELLO_OK`; verify exit 0; negative marker test exit 1.
+  - Reset refused symlinked dataRoot; canary file survived; real reset removed only the configured data root.
+  - config.json checksum unchanged across hello/verify/reset/bootstrap/build/verify.
+- Failure or correction:
+  1. Selftest harness bug: `cfg` helper invoked without a body for the symlink case (`$2: unbound variable`). Fixed in the harness; product code unaffected.
+  2. E2E rerun-after-reset failure: `verify.sh` did not ensure the configured data root existed before the container mount. With the data root absent, Docker auto-created the host path as root:root, and the container's uid-1000 user could not write the generated system prompt. Fixed by calling `bootstrap_runtime_dir` in `verify.sh`; also hardened it to fail with a clear message when the data root exists but is not writable (root-owned leftover). Clean-slate E2E rerun: all steps green.
+- Credential check: no credential material in config, scripts, logs, or test output.

+## Result (M1)
+
+Configuration-driven Hello World verified. `main` merged with M1 and tagged `config-hello-v1`.

+# LAYERS
+
+Deferred capability layers for the Mosaic experiment. Only L0 is implemented by
+this proof of concept; everything below it is documented here and deliberately
+not implemented (see BRIEF.md, "Explicit exclusions").
+
+## L0 — Implemented: container returns MOSAIC_HELLO_OK
+
+One image (`mosaic-poc-agent:0.84.4`, built on `node:24-bookworm-slim`, non-root,
+pinned Pi) runs one Pi agent one-shot. Four immutable local contract files are
+loaded in fixed order into the generated system prompt
+(`/var/lib/mosaic/system-prompt.md`). One real model request is sent
+noninteractively; the response must equal `MOSAIC_HELLO_OK` exactly or the
+verification exits nonzero. Authentication is supplied at runtime only
+(read-only mounted pi auth file, or a provider API key environment variable).
+
+## L1 — Deferred: persist and resume a named Pi session
+
+Keep a named Pi session across container runs (`--name`, session storage under
+`/var/lib/mosaic`), resume it with the documented session flags, and verify
+state survives a container restart.
+
+## L2 — Deferred: fixed tool permission policy
+
+Add a fixed allow/deny policy for Pi tools (e.g. restricting built-in tools via
+documented `--tools` / `--exclude-tools` or an extension-based permission gate),
+so contract files can constrain what the agent may do, not just what it says.
+
+## L3 — Deferred: load full versioned contract bundles
+
+Replace the four static fixtures with versioned contract bundles: bundle
+manifests, contract versions, and deterministic ordering/hashing, loaded from
+an immutable bundle artifact instead of files copied at image build time.
+
+## L4 — Deferred: Claude as a second runtime
+
+Add a second runtime (Claude) alongside the Pi agent in the same container
+stack, behind the same contract-loading path, to compare behavior across
+runtimes.
+
+## L5 — Deferred: multiple agents and communication
+
+Run several named agents with defined roles and a communication channel between
+them (message passing or shared state under `/var/lib/mosaic`).
+
+## L6 — Deferred: orchestration, knowledge storage, and portal features
+
+Fleet-level orchestration, knowledge storage, monitoring, and portal UI on top
+of L1-L5. This is where the existing Mosaic Stack concepts would be re-evaluated
+from first principles.

-# Mosaic Stack
+# Minimal Mosaic Stack container POC

-Self-hosted, multi-user AI agent platform. One config, every runtime, same standards.
+Standalone experiment, not part of the Mosaic Stack repository or Software Factory.

-Mosaic gives you a unified launcher for Claude Code, Codex, OpenCode, and Pi — injecting consistent system prompts, guardrails, skills, and mission context into every session. A NestJS gateway provides the API surface, a Next.js dashboard gives you the UI, and a plugin system connects Discord, Telegram, and more.
+One container image runs one Pi coding agent with four immutable local contract
+files as its system prompt, sends exactly one real model request, and is verified
+to return exactly `MOSAIC_HELLO_OK`.

-The installer auto-launches the setup wizard, which walks you through gateway install and verification. Flags for non-interactive use:

-bash <(curl -fsSL …) --yes --no-auto-launch  # Install only, skip wizard

-| ----------------------- | ---------------------------------------------------------------- | -------------------- |
-| **Framework**           | Bash launcher, guides, runtime configs, tools, skills            | `~/.config/mosaic/`  |
-| **@mosaicstack/mosaic** | Unified `mosaic` CLI — TUI, gateway client, wizard, auto-updater | `~/.npm-global/bin/` |
-
-After install, the wizard runs automatically or you can invoke it manually:
+Created only by the explicit, idempotent bootstrap:

 ```bash
-mosaic wizard        # Full guided setup (gateway install → verify)
+scripts/bootstrap.sh   # create-if-absent; validates existing config, never rewrites
 ```

-### Requirements
+Minimal shape (`configVersion` 1):

- Node.js ≥ 20
- npm (for global @mosaicstack/mosaic install)
- One or more runtimes: [Claude Code](https://docs.anthropic.com/en/docs/claude-code), [Codex](https://github.com/openai/codex), [OpenCode](https://opencode.ai), or [Pi](https://github.com/mariozechner/pi-coding-agent)
+```json
+{
+  "configVersion": 1,
+  "environment": "development",
+  "dataRoot": "/home/jwoltje/.mosaic-dev",
+  "execution": {
+    "backend": "docker",
+    "provider": "zai",
+    "model": "glm-5.3-flash"
+  }
+}
+```
+
+Rules enforced by `scripts/mosaic-config.mjs`:
+
+- Unknown keys, unsupported versions/backends, and malformed JSON exit nonzero; nothing is modified.
+- `dataRoot` must be absolute, canonical, and must not be or contain the home or configuration directory.
+- Validation failures never touch config, state, or images.
+- `scripts/test-config.sh` runs the sandboxed config selftests (no Docker required).
+
+Run paths (`build/hello/verify/reset`) fail closed when configuration is missing or invalid; they never invent it.
+
+See `docs/plans/2026-09-02_atomic-mosaic-foundation.md` for the full plan.
+
+Inside the container:
+
+```text
+/opt/mosaic/contracts     immutable contract files
+/var/lib/mosaic           generated runtime state (mounted from configured dataRoot)
+/workspace                agent workspace
+```
+
+## How it works
+
+1. `scripts/build.sh` builds `mosaic-poc-agent:0.84.4` with Docker Compose.
+2. On each run, `/opt/mosaic/src/load-contracts.sh` reads the four contract files
+   in fixed order (CONSTITUTION, STANDARDS, SOUL, USER), joins them with clear
+   separators, and writes `/var/lib/mosaic/system-prompt.md`.
+3. `/opt/mosaic/src/run-agent.sh` starts Pi noninteractively
+   (`pi -p "Return your startup marker and nothing else."`) with
+   `--system-prompt "$(cat /var/lib/mosaic/system-prompt.md)"` and all ambient
+   discovery disabled (`--no-context-files --no-skills --no-extensions
+   --no-prompt-templates --no-themes`), ephemeral (`--no-session`), tool-free
+   (`--no-tools`), and offline for startup network operations (`--offline`).
+4. `scripts/verify.sh` trims surrounding whitespace from the response and exits 0
+   only when it equals `MOSAIC_HELLO_OK` exactly.

 ## Usage

-### Launching Agent Sessions
+```bash
+scripts/bootstrap.sh   # create config.json if absent (idempotent)
+scripts/build.sh       # build the image
+scripts/hello.sh       # one-shot request; prints the model response
+scripts/verify.sh      # full gated test; exit 0 only on exact MOSAIC_HELLO_OK
+scripts/test-config.sh # fast config-layer selftests (no Docker)
+scripts/reset.sh       # delete the configured data root (safety-checked)
+```
+
+Prove the failure path (acceptance criterion 9):

 ```bash
-mosaic pi                    # Launch Pi with Mosaic injection
-mosaic claude                # Launch Claude Code with Mosaic injection
-mosaic codex                 # Launch Codex with Mosaic injection
-mosaic opencode              # Launch OpenCode with Mosaic injection
-
-mosaic yolo claude           # Claude with dangerous-permissions mode
-mosaic yolo pi               # Pi in yolo mode
+EXPECTED_MARKER=MOSAIC_NOT_OK scripts/verify.sh   # must exit nonzero
 ```

-The launcher verifies your config, checks for `SOUL.md`, injects your `AGENTS.md` standards into the runtime, and forwards all arguments.
+## Authentication

-### TUI & Gateway
+Pi's documented container authentication (see the package's
+`docs/containerization.md`) is used, in this order:

-```bash
-mosaic tui                   # Interactive TUI connected to the gateway
-mosaic gateway login         # Authenticate with a gateway instance
-mosaic sessions list         # List active agent sessions
-```
+1. **Read-only mounted credential file** (default): the host pi auth file
+   `~/.pi/agent/auth.json` is bind-mounted read-only to
+   `/home/node/.pi/agent/auth.json`. The host file holds a static API-key
+   entry for the built-in `zai` provider, so no token refresh writes are needed.
+2. **Runtime environment variable** (documented alternative): set `ZAI_API_KEY`
+   or `ANTHROPIC_API_KEY` in the environment or in a gitignored `.env`; compose
+   passes them through. Pi's documented precedence applies.

-### Gateway Management
+Credentials are never committed, never copied into the image, and never printed.
+`.env.example` contains non-secret settings only.

-```bash
-mosaic gateway install       # Install and configure the gateway service
-mosaic gateway verify        # Post-install health check
-mosaic gateway login         # Authenticate and store a session token
-mosaic gateway config rotate-token    # Rotate your API token
-mosaic gateway config recover-token  # Recover a token via BetterAuth cookie
-```
+## Boundaries honored

-If you already have a gateway account but no token, use `mosaic gateway config recover-token` to retrieve one without recreating your account.
-
-### Configuration
-
-```bash
-mosaic config show           # Print full config as JSON
-mosaic config get <key>      # Read a specific key
-mosaic config set <key> <val># Write a key
-mosaic config edit           # Open config in $EDITOR
-mosaic config path           # Print config file path
-```
-
-### Management
-
-```bash
-mosaic doctor                # Health audit — detect drift and missing files
-mosaic sync                  # Sync skills from canonical source
-mosaic update                # Check for and install CLI updates
-mosaic wizard                # Full guided setup wizard
-mosaic bootstrap <path>      # Bootstrap a repo with Mosaic standards
-mosaic coord init            # Initialize a new orchestration mission
-mosaic prdy init             # Create a PRD via guided session
-```
-
-### Sub-package Commands
-
-Each Mosaic sub-package exposes its API surface through the unified CLI:
-
-```bash
-# User management
-mosaic auth users list
-mosaic auth users create
-mosaic auth sso
-
-# Agent brain (projects, missions, tasks)
-mosaic brain projects
-mosaic brain missions
-mosaic brain tasks
-mosaic brain conversations
-
-# Agent forge pipeline
-mosaic forge run
-mosaic forge status
-mosaic forge resume
-mosaic forge personas
-
-# Structured logging
-mosaic log tail
-mosaic log search
-mosaic log export
-mosaic log level
-
-# MACP protocol
-mosaic macp tasks
-mosaic macp submit
-mosaic macp gate
-mosaic macp events
-
-# Agent memory
-mosaic memory search
-mosaic memory stats
-mosaic memory insights
-mosaic memory preferences
-
-# Task queue (Valkey)
-mosaic queue list
-mosaic queue stats

-mosaic queue resume
-mosaic queue jobs
-mosaic queue drain
-
-# Object storage
-mosaic storage status
-mosaic storage tier
-mosaic storage export
-mosaic storage import
-mosaic storage migrate
-```
-
-### Telemetry
-
-```bash
-# Local observability (OTEL / Jaeger)
-mosaic telemetry local status
-mosaic telemetry local tail
-mosaic telemetry local jaeger
-
-# Remote telemetry (dry-run by default)
-mosaic telemetry status
-mosaic telemetry opt-in
-mosaic telemetry opt-out
-mosaic telemetry test
-mosaic telemetry upload        # Dry-run unless opted in
-```
-
-Consent state is persisted in config. Remote upload is a no-op until you run `mosaic telemetry opt-in`.
-
-## Development
-
-### Prerequisites
-
- Node.js ≥ 20
- pnpm 10.6+
- Docker & Docker Compose
-
-### Setup

-
-### Key Design Decisions
-
- **Gateway is the single API surface** — all clients (TUI, web, Discord, Telegram) connect through it
- **ESM everywhere** — `"type": "module"`, `.js` extensions in imports, NodeNext resolution
- **Socket.IO typed events** — defined in `@mosaicstack/types`, enforced at compile time
- **OTEL auto-instrumentation** — loads before NestJS bootstrap
- **Explicit `@Inject()` decorators** — required since tsx/esbuild doesn't emit decorator metadata
-
-### Framework (`~/.config/mosaic/`)
-
-The framework is the bash-based standards layer installed to every developer machine:
-
-```
-~/.config/mosaic/
-├── AGENTS.md              ← Central standards (loaded into every runtime)
-├── SOUL.md                ← Agent identity (name, style, guardrails)
-├── USER.md                ← User profile (name, timezone, preferences)
-├── TOOLS.md               ← Machine-level tool reference
-├── bin/mosaic             ← Unified launcher (claude, codex, opencode, pi, yolo)
-├── guides/                ← E2E delivery, orchestrator protocol, PRD, etc.
-├── runtime/               ← Per-runtime configs (claude/, codex/, opencode/, pi/)
-├── skills/                ← Universal skills (synced from agent-skills repo)
-├── tools/                 ← Tool suites (orchestrator, git, quality, prdy, etc.)
-└── memory/                ← Persistent agent memory (preserved across upgrades)
-```
-
-### Forge Pipeline
-
-Forge is a multi-stage AI pipeline for autonomous feature delivery:
-
-```
-Intake → Discovery → Board Review → Planning (3 stages) → Coding → Review → Remediation → Test → Deploy
-```
-
-Each stage has a dispatch mode (`exec` for research/review, `yolo` for coding), quality gates, and timeouts. The board review uses multiple AI personas (CEO, CTO, CFO, COO + specialists) to evaluate briefs before committing resources.
-
-## Upgrading
-
-Run the installer again — it handles upgrades automatically:
-
-```bash
-bash <(curl -fsSL https://git.mosaicstack.dev/mosaicstack/mosaic-stack/raw/branch/main/tools/install.sh)
-```
-
-Or use the CLI:
-
-```bash
-mosaic update                # Check + install CLI updates
-mosaic update --check        # Check only, don't install
-```
-
-The CLI also performs a background update check on every invocation (cached for 1 hour).
-
-### Installer Flags
-

- *
- * Test strategy:
- *  - Two real users (User A, User B) are inserted directly into the database.
- *  - Realistic data (conversations + messages, agent configs, preferences,
- *    insights) is created for each user.
- *  - A shared system agent is inserted so both users can see it via

- *  - All assertions are made against the live database (no mocks).
- *  - All inserted rows are cleaned up in the afterAll hook.
- *
- * Requires: DATABASE_URL pointing at a running PostgreSQL instance with
- * pgvector enabled and the Mosaic schema already applied.

jason.woltje	ce6420f3de	Merge M1: configuration-driven Hello World Closes #1, closes #2, closes #3, closes #4	2026-09-02 18:32:50 -05:00
jason.woltje	81f58b15c8	fix(launcher): ensure configured data root before verify mount; docs for M1 (#4 ) - verify.sh now calls bootstrap_runtime_dir after load_config; previously a reset-then-verify flow let Docker auto-create a root-owned mount source - common.sh: fail with clear guidance when data root exists but is not writable - README: configuration section, bootstrap usage, selftest entry point - BUILD-LOG: Phase 5 entries with corrections E2E (clean slate): 20/20 selftests; bootstrap idempotent; config-driven hello/verify MOSAIC_HELLO_OK; negative marker exit 1; reset + rerun green; config checksum unchanged across the entire flow. Closes #4	2026-09-02 18:32:50 -05:00
jason.woltje	0c2113f710	test(config): sandboxed config-layer selftests (#3 ) 20 cases: bootstrap create/idempotency, missing config, malformed JSON, unknown keys/version/backend/environment, relative and non-canonical dataRoot, filesystem root, home dir, ancestor-of-config, control chars, symlinked config file, env export resolution, validation-writes-nothing. Closes #3	2026-09-02 18:30:46 -05:00
jason.woltje	900a506c1f	feat(config): wire launcher scripts and compose to config.json (#2 ) - common.sh: load_config() exports MOSAIC_DATA_ROOT/PROVIDER/MODEL; fails closed - compose.yaml: dataRoot mount and provider/model are required env (:? errors) - build/hello/verify load config before any mutation; no silent bootstrap - reset.sh: target resolved from configured dataRoot; all safety checks kept Verified: compose fails without launcher env; verify/reset fail on missing config; config-driven hello+verify pass; symlink refusal with sandboxed config (canary survived); config checksum unchanged across reset+rerun. Closes #2	2026-09-02 18:30:08 -05:00
jason.woltje	c3d29e796a	feat(config): config module with idempotent bootstrap and strict v1 validation (#1 ) - scripts/mosaic-config.mjs: bootstrap \| validate \| env operations - Exclusive creation (O_EXCL 'wx'); existing config validated, never rewritten - Strict schema: unknown keys rejected, configVersion===1, backend docker only - dataRoot guards: absolute, canonical, not root/home/ancestor-of-config - MOSAIC_CONFIG override for sandboxed tests; exit codes 0/2/3 - scripts/bootstrap.sh: explicit bootstrap entry point Closes #1	2026-09-02 18:28:14 -05:00
jason.woltje	c2365ae519	chore: baseline container POC and atomic foundation plan - Containerized Pi hello-world proof (image mosaic-poc-agent:0.84.4, non-root) - Four immutable contract fixtures loaded into a generated system prompt - build/hello/verify/reset scripts with exact-match gating and reset safety - Documented Pi discovery (v0.84.4, -p mode, --system-prompt, container auth) - Append-only BUILD-LOG with corrections; deferred layers in LAYERS.md - Architecture plan: docs/plans/2026-09-02_atomic-mosaic-foundation.md	2026-09-02 18:24:36 -05:00
