-# 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
-```

+## What this repository is
 
-## Project Context
+A standalone rebuild of Mosaic Stack: a file-based, fail-closed
+orchestration foundation that dispatches sandboxed headless pi workers to do
+real work, with immutable run records as evidence. Thirteen-plus tagged
+milestones (`git tag -l`) from `poc-container-hello-v0` to today; suites
+green at every step. Not production software — a proven foundation.
 
-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.
+## Non-negotiable invariants (the canon)
 
-## Package Map
+1. **Root is bootstrap-only.** First-class system configuration lives at the
+   repository root; everything else gets a dedicated directory (`roles/`,
+   `contracts/`, `missions/`, `tasks/`, `docs/`). Do not add new files to root.
+2. **Configuration**: `~/.config/mosaic-dev/config.json` is the sole system
+   config — created only by `scripts/bootstrap.sh`, never overwritten,
+   fail-closed on any problem. Repo-scoped role authority lives in
+   `roles/*.json` (versioned, reviewed commits only).
+3. **Secrets** never enter the repository or container images; auth is
+   runtime-only (read-only mount or environment variable).
+4. **Contracts** (`contracts/`) are immutable and image-baked. Missions and
+   tasks are declarative JSON with strict schemas.
+5. **Run records** under `<dataRoot>/runs/` are write-once evidence — never
+   rewritten, only pruned via `prune` with a receipt.
+6. **Fail closed**: missing or invalid config/policy refuses the operation.
+   Never improvise around a refusal; diagnose it.
+7. **Policy**: missions govern tasks (least-privilege intersection — a task
+   narrows, never widens). Role authority is declared in `roles/` and changes
+   only via reviewed commits.
+8. **Git**: commit only after suites are green; push only `main`; never
+   force-push. `scripts/conductor-apply.sh` commits locally — push stays an
+   explicit act.
+9. **Append-only logs**: BUILD-LOG.md (phases), `activation-log.jsonl`,
+   `.pruned.log`, docs/SESSIONS.md. Corrections are new entries, never edits.

+## Session protocol (mandatory)
 
-## Architecture Rules
+- **Register** your session in `docs/SESSIONS.md` — one append-only line
+  (date, actor, scope, outcome). Never rewrite or remove entries.
+- **Cadence**: read `docs/plans/CURRENT.md` → execute its single next action
+  fully (implement → test → verify against acceptance criteria → commit →
+  push → close issue) → update CURRENT.md → register in SESSIONS.md.
+- "next" means one action. A batch mandate ("run the queue") repeats the
+  loop until green or blocked. Blocked means stop and report, never improvise.
+- Substantial work gets a Gitea issue and a BUILD-LOG phase entry
+  (before/after, with corrections recorded honestly).
 
-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 `@mosaic/types` enforce compile-time contracts
-4. OTEL auto-instrumentation loads before NestJS bootstrap
-5. BetterAuth manages auth tables; schema defined in `@mosaic/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)
+## Role model
 
-## Development Workflow
+- **Conductor**: a system-scoped role — not an agent, not a daemon. Holds
+  git/credentials/policy authority; decomposes, dispatches, reviews,
+  verifies, integrates. Protocol: `docs/plans/CONDUCTOR.md`. Exists only
+  when invoked; push is never automatic.
+- **Workers**: headless pi via `scripts/run-task.sh` — sandboxed workspace,
+  tools allowlist, optional persistent sessions and forks; no git, no
+  credentials, no policy control.
+- Worker runs deliberately exclude this file (`--no-context-files` in the
+  adapter): worker context is contracts + mission via the generated system
+  prompt. This file is for conductor-level sessions.

+- `~/.config/mosaic-dev/config.json` — system config (user-authored; never

+- `<dataRoot>` (from config; default `~/.mosaic-dev`):
+  - `runs/` — write-once run evidence (`result.json`, snapshots, `stderr.txt`)
+  - `sessions/` — pi JSONL session trees, one directory per named session
+  - `workspaces/` — agent file effects (persistent or `:run` ephemeral)
+  - `state/` — release pointer + append-only activation/auto-apply logs
+- Ownership is per-directory; nothing shares state. Directory map and
+  lifecycle rules: README.md "Data map" section.

+## Pointers (depth lives here)
+
+- `docs/plans/CURRENT.md` — THE next action (single source of "what now")
+- `docs/plans/CONDUCTOR.md` — orchestration protocol and guardrails
+- `docs/plans/2026-09-02_atomic-mosaic-foundation.md` — architecture, invariants
+- `docs/plans/2026-09-03_autonomous-run.md` — batch-run tracker
+- `BUILD-LOG.md` — append-only build/verification history with corrections
+- `LAYERS.md` — implemented vs deferred layers
+- `docs/SESSIONS.md` — session registry
+- `adapters/README.md` — the harness adapter contract
+- `roles/` — role contracts (conductor, future agent/coder/reviewer)
+
+## Recovery rule
+
+Compacted, restarted, or new? Nothing that matters is lost: this file +
+`docs/plans/CURRENT.md` + `git log --oneline -10` + the suites reconstruct
+the full state. **Never guess** — verify with the suites; the run records
+and logs hold the receipts.
+
+## Version pin
+
+`@earendil-works/pi-coding-agent` is pinned exactly (see `package.json` /
+`RELEASE`); never install unversioned. Release identity: `RELEASE` file
+(0.0.X until declared stable); image tags derive from it.

+# 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

+
+## 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`.
+
+---
+
+## Phase 6: Mission and task abstraction (M2)
+
+### Entry 6.1 — before
+
+- Timestamp: 2026-09-03
+- Intended action: Add the first mission/task layer, host-side only (Gitea milestone M2, issues #6-#9): strict v1 schemas for missions and tasks, a task runner executing through the proven config-driven container path, immutable write-once run records under `<dataRoot>/runs/`, `expectExact` gating, timeouts, selftests, fixtures, and docs.
+- Reason: The foundation plan's following layer — mission (objective + directives), task (bounded unit), run (one attempt), result (immutable evidence) — must exist as data and records before any policy or multi-agent work.
+- Expected result: `scripts/run-task.sh tasks/hello-marker.json` succeeds with exactly `MOSAIC_HELLO_OK`; wrong expectations fail; every run leaves an immutable record; configuration remains untouched.
+
+### Entry 6.2 — after
+
+- Timestamp: 2026-09-03
+- Commands run: `scripts/test-task.sh` (18 cases incl. live runs); `scripts/run-task.sh validate` / `run` on committed fixtures; `node scripts/mosaic-task.mjs list`; config checksum comparison across runs.
+- Observed result:
+  - Selftests: 18 passed, 0 failed (schema negatives; live exact-marker success; wrong expectExact fails; distinct run dirs; result.json contents; list).
+  - Fixture run: status `succeeded`, response exactly `MOSAIC_HELLO_OK`, mission snapshot recorded.
+  - Run records written once under `<dataRoot>/runs/r-<utcstamp>-<rand>/`; reruns never clobber.
+- Failure or correction: none this phase.
+- Credential check: no credential material in task data, run records, or logs.
+
+## Result (M2)
+
+Mission/task layer verified end-to-end. `main` merged with M2 and tagged `mission-task-v1`.
+
+---
+
+## Phase 7: Release model and safe updates (M3)
+
+### Entry 7.1 — before
+
+- Timestamp: 2026-09-03
+- Intended action: Add the release substrate (Gitea milestone M3, issues #10-#13): RELEASE file single-sources the version (0.0.X line per owner direction), image tags derive from it, scripts/release.sh provides package/activate/rollback/status, activation is health-gated by the M2 task runner, pointer + append-only log under <dataRoot>/state/.
+- Reason: The owner's top invariant — updates must never corrupt a working installation — needs a mechanism, not a convention: gate-then-flip with recorded history and rollback.
+- Expected result: Update, refusal, and rollback drills all green with config checksums unchanged.
+
+### Entry 7.2 — after
+
+- Timestamp: 2026-09-03
+- Commands run: scripts/test-release.sh (14 cases); recorded drills: update (0.0.3 -> 0.0.4 package+activate+verify), fault-injected refusal, rollback to 0.0.3.
+- Observed result:
+  - Selftests: 14 passed, 0 failed.
+  - Update drill: packaged and activated r0.0.4 after exact-marker health gate; verify green under the new tag; config checksum unchanged.
+  - Refusal drill: health-gate fault injection -> activation refused (exit 1), pointer untouched, refusal appended to the log.
+  - Rollback drill: health-gated rollback to r0.0.3; pointer restored; log records package/activate/refused/rollback history append-only.
+- Failure or correction:
+  1. release.sh initially failed with missing state/ directory (no mkdir before pointer/log writes); fixed.
+  2. Selftest harness mutated the repo RELEASE and restored the mutated copy (mv-back bug) plus a second trap replacing the first; fixed with inline backup restore and one self-healing exit trap. Product code unaffected.
+- Credential check: no credential material in release state, logs, or drills.
+
+## Result (M3)
+
+Release model and safe updates verified by drills. `main` merged with M3 and tagged `release-model-v1`.
+
+---
+
+## Phase 8: Runtime adapter seam (M4)
+
+### Entry 8.1 — before
+
+- Timestamp: 2026-09-03
+- Intended action: Formalize the harness boundary (Gitea milestone M4, issues #16-#19): documented adapter contract under /opt/mosaic/adapters/<name>/adapter.sh; run-agent.sh becomes a dispatcher; pi extracted unchanged; deterministic mock adapter for provider-free seam tests; config gains optional execution.adapter (default pi, configVersion unchanged); mission directives gain their sanctioned injection point via the run snapshot; RELEASE bumps to 0.0.5 with a health-gated activation.
+- Reason: Future harnesses (Claude, Codex, OpenCode) must be additive — one directory each — and mission content needs a single sanctioned path into the runtime.
+- Expected result: All suites green including new deterministic seam cases; 0.0.5 activated by health gate; mission-bearing run recorded.
+
+### Entry 8.2 — after
+
+- Timestamp: 2026-09-03
+- Commands run: scripts/test-config.sh; scripts/test-task.sh; scripts/test-release.sh; manual seam drills (mock verbatim, unknown/traversal adapter refusal); mission injection checks; release package + activate for 0.0.5.
+- Observed result:
+  - Config suite 24/24 (adapter default/validation/env export).
+  - Task suite 24/24 including deterministic mock cases (gate pass, expect-mismatch with reason, unknown adapter fail-closed) and mission injection asserted by prompt content.
+  - Release suite 14/14; image mosaic-poc-agent:0.84.4-r0.0.5 packaged and activated via exact-marker health gate.
+  - Mission directives now flow: task -> run snapshot -> container env -> generated prompt MISSION (runtime) section.
+- Failure or correction:
+  1. Selection authority settled: load_config always exports MOSAIC_ADAPTER from config; environment overrides for scripts are therefore not a supported selection path (by design).
+  2. Selftest harness: three authoring defects fixed (helpers used before definition; one config file reused across cases leaking adapter state; a static mission fixture asserted against distinctive seam directives; plus an accidentally duplicated live block removed).
+- Credential check: no credential material in adapters, prompts, run records, or logs.
+
+## Result (M4)
+
+Adapter seam verified; harness boundary is now additive by construction. `main` merged with M4 and tagged `adapter-seam-v1`.
+
+---
+
+## Phase 9: Workspaces + capability envelope (M5)
+
+### Entry 9.1 — before
+
+- Timestamp: 2026-09-03
+- Intended action: Optional task workspace (absent / ":run" ephemeral / named persistent) and capabilities.tools allowlist (pi built-ins); runner plumbing via MOSAIC_WORKSPACE/MOSAIC_TOOLS; pi adapter maps to cwd + --tools; mock adapter logs delivered MOSAIC_* vars for deterministic assertions (Gitea #20, #21).
+- Reason: Agents that only answer text cannot do work; the workspace+tools pair is the smallest real capability step, bounded by the container.
+- Expected result: plumbing asserted via run-record stderr; live pi writes a host-visible file.
+
+### Entry 9.2 — after
+
+- Timestamp: 2026-09-03
+- Commands run: build; mock plumbing run; validate negatives; full task suite; live workspace demo.
+- Observed result: task suite 32/32; MOSAIC_WORKSPACE/MOSAIC_TOOLS asserted in run record; dataRoot/workspaces/<name> created host-side; live pi used bash to write proof.txt into the demo workspace (host-visible).
+- Failure or correction: (1) batch edit dropped SUPPORTED_TOOLS const (runtime ReferenceError, exit 1 instead of 2) — restored; (2) mock env dump used `export` which this dash prints as `export K='v'` — switched to `env`; (3) selftest fed a mismatching mock response to the plain-task case — test bug, fixed.
+
+## Phase 10: Named sessions (M6)
+
+### Entry 10.1 — before
+
+- Timestamp: 2026-09-03
+- Intended action: Optional task.session name -> persistent session dir dataRoot/sessions/<name> via pi --session-dir; resume most recent with -c when present; isolation per name; teach/recall demo fixtures (Gitea #22, #23).
+- Reason: L1 persistence is the prerequisite for any multi-step agent work.
+- Expected result: session dir populated after first run; second run recalls taught context.
+
+### Entry 10.2 — after
+
+- Timestamp: 2026-09-03
+- Commands run: build; mock plumbing run; live teach/recall E2E; task suite.
+- Observed result: task suite 32/32; teach run replied REMEMBERED and session JSONL persisted host-side; recall run resumed (-c) and answered exactly 'mosaico'; single continued session file (no duplicate sessions).
+- Failure or correction: none. Design note: ephemeral (--no-session) remains the default when no session is declared.
+
+## Phase 11: Operator ergonomics (M7)
+
+### Entry 11.1 — before
+
+- Timestamp: 2026-09-03
+- Intended action: mosaic-task.mjs show <runId> (full record + snapshots + artifacts, traversal-safe), list with workspace/session columns, RELEASE -> 0.0.6, package + health-gated activate, docs (Gitea #24).
+- Reason: Run records are only as valuable as they are inspectable; release activation closes the loop on container-content changes.
+- Expected result: show works for real/missing/traversal ids; suites green; 0.0.6 active.
+
+### Entry 11.2 — after
+
+- Timestamp: 2026-09-03
+- Commands run: build; show on real/missing/traversal ids; full sweep; release package + activate.
+- Observed result: config 24/24, task 32/32, release 14/14, verify PASS; 0.0.6 packaged and activated via exact-marker health gate.
+- Failure or correction: showRun initially rejected valid run ids (lowercase-only regex vs uppercase timestamp) and crashed on missing ids (uncaught readdir) — both fixed and covered.
+
+## Autonomous run result
+
+M5 tagged `workspace-capabilities-v1`, M6 tagged `sessions-v1`, M7 tagged `operator-ergonomics-v1`; release 0.0.6 active. Tracker: docs/plans/2026-09-03_autonomous-run.md.

+## Phase 12: Conductor loop — self-orchestration (M8)
+
+### Entry 12.1 — before
+
+- Timestamp: 2026-09-03
+- Intended action: Stand up the poor-man orchestration loop per docs/plans/CONDUCTOR.md: conductor (host, holds git) mirrors the repo into a worker workspace, dispatches a headless pi worker (session worker-1, tools read/write/edit/bash) to implement retry <runId>, reviews the diff, integrates, verifies (Gitea #25, #26, #27).
+- Reason: The owner asked for circular task processing with agent workers; the stack now has every primitive needed — this proves it on the stack itself.
+- Expected result: worker-authored retry merged with suites green and a live retry verified.
+
+### Entry 12.2 — after
+
+- Timestamp: 2026-09-03
+- Commands run: repo mirror clone; worker dispatch (tasks/worker-retry.json); diff review; apply; live retry; refinement dispatch (tasks/worker-retry-refine.json); second review; reverse+reapply combined patch; conductor interpolation fix; live retry; full sweep.
+- Observed result:
+  - Worker round 1: implemented retry correctly per spec in 2m28s; diff reviewed clean.
+  - Live retry exposed a spec gap (direct invocation lacks launcher env exports).
+  - Worker round 2 (same session, 59s): made spawnEnv self-sufficient, but used PI_* names where compose interpolates MOSAIC_*.
+  - Conductor hotfix: 3-line rename to MOSAIC_PROVIDER/MOSAIC_MODEL/MOSAIC_DATA_ROOT (too trivial for a worker round).
+  - Final: live retry succeeded (replied REMEMBERED, new run recorded); all suites green.
+- Failure or correction: three rounds total — one spec gap (conductor), one naming mismatch (worker), one trivial rename (conductor). Each was caught by mechanical verification (run record stderr), never by hope.
+- Attribution: feature authored by headless pi worker (glm-5.3-flash) in sessions worker-1; conductor reviewed, integrated, and hotfixed.
+
+## Result (M8)
+
+Conductor loop proven end-to-end on the stack itself. `main` merged with M8; release 0.0.6 remains active (retry is host-side only, no image change).
+
+---
+
+## Phase 13: Mission-level capability policy (M9)
+
+### Entry 13.1 — before
+
+- Timestamp: 2026-09-03
+- Intended action: Missions may declare capabilities.tools as governing constraints (Gitea #30); merge semantics = least-privilege intersection (task narrows, never widens; empty intersection = tool-free run). Host-side only.
+- Reason: First mechanical restriction layer — the trust model becomes enforced, not instructed.
+- Expected result: all four merge cases asserted from run evidence; suites green.
+
+### Entry 13.2 — after
+
+- Observed: four merge cases verified deterministically via run-record stderr (mission-only, task-only, narrowed, emptied); invalid mission capabilities exit 2; task suite 41/41.
+- Failure or correction: selftest harness could not express ABSENT vs EMPTY fields via its printf helper — fixed with an ABSENT marker; two suite config-leak defects fixed (per-command env scoping). Product unaffected.
+
+## Phase 14: Session forking (M11)
+
+### Entry 14.1 — before
+
+- Timestamp: 2026-09-03
+- Intended action: sessionForkFrom task field branches the source session's newest file (pi --fork) into the target session dir; ancestor untouched; RELEASE -> 0.0.7 with health-gated activation (Gitea #33).
+- Reason: Owner flagged conversation forking from a common ancestor as a desired property; pi JSONL trees make it native.
+- Expected result: forked child recalls ancestor context; ancestor file untouched; suites green; 0.0.7 active.
+
+### Entry 14.2 — after
+
+- Observed: mock plumbing asserts fork source + target delivery; validation rejects fork-without-target and self-fork (exit 2); ghost source exits 4; live fork: child recalled 'mosaico' from ancestor context while the ancestor session file remained untouched (file-level assertion); suites 58/24/14 + verify green; 0.0.7 packaged and activated via health gate.
+- Failure or correction: retryRun-style self-assignment bug in validation (compared null to target) — caught by negative test, fixed.
+
+## Result (M11)
+
+Session forking verified. `main` merged with M11, tagged `session-fork-v1`; release 0.0.7 active.
+
+---
+
+## Phase 15: Interactive TUI agent + TOOLS.md (M13)
+
+### Entry 15.1 — before
+
+- Timestamp: 2026-09-03
+- Intended action: Add scripts/agent.sh — an interactive TUI launcher (contracts + optional mission + agent identity + named session + optional workspace/tools) — and the pi-adapter interactive branch; remove the fixed compose command; add docs/TOOLS.md as the on-demand reference AGENTS.md routes to; RELEASE -> 0.0.8 (Gitea #35).
+- Reason: The owner's bootstrap model is vanilla pi sessions directed by AGENTS.md, graduating to governed TUI agents — the first the system itself launches.
+- Expected result: TUI agent launches with contracts+identity context; headless paths unchanged; TOOLS.md consolidates the reference.
+
+### Entry 15.2 — after
+
+- Observed: mock plumbing asserts agent name/session/workspace/mission delivery; identity section asserted in generated prompt; headless hello + suites green (24/58/17/14 + verify); 0.0.8 packaged and health-gated activated.
+- Failure or correction:
+  1. Regression: pi adapter rewrite made MOSAIC_AGENT_NAME unconditionally required, breaking headless paths — caught by task suite (empty-stderr exit-nonzero), fixed (optional in headless; identity section simply omitted).
+  2. Regression: unquoted $REQUEST_ARG word-split the request into positional args — fixed with positional-argument building (set -- ... "$@").
+  3. Mission fixture wording (objective named the agent) invited the model to append its name after the marker, tripping the strict gate — fixture tightened; strict gate kept by design.
+- Conductor session env hygiene: sandbox config exports now scoped per-command after a leak broke cross-suite runs.
+
+## Result (M13)
+
+Interactive TUI agent launched and verified; TOOLS.md reference shipped. `main` merged with M13, tagged `interactive-agent-v1`; release 0.0.8 active.

+# 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.

+```
+
+## Configuration
+
+The sole discovery entry point is:
+
+```text
+~/.config/mosaic-dev/config.json
+```
+
+Created only by the explicit, idempotent bootstrap:
+
+```bash
+scripts/bootstrap.sh   # create-if-absent; validates existing config, never rewrites
+```
+
+Minimal shape (`configVersion` 1):
+
+```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.
+
+## Missions & tasks (M2)
+
+Missions and tasks are validated JSON data (strict schemas, version-pinned). The M2 layer is host-side only: mission directives are recorded for provenance but do not yet reach the runtime system prompt (capability/policy layer comes later).
+
+```text
+missions/hello.json          objective + directives (missionVersion 1)
+tasks/hello-marker.json      prompt + optional mission ref + expectExact + timeout
+<dataRoot>/runs/r-<id>/      immutable run record: task.json, mission.json,
+                             stderr.txt, result.json (all write-once)
+```
+
+Usage:
+
+```bash
+scripts/run-task.sh validate tasks/hello-marker.json   # strict validation, writes nothing
+scripts/run-task.sh run tasks/hello-marker.json        # execute; result recorded under dataRoot/runs
+scripts/mosaic-task.mjs list                           # list runs and statuses
+scripts/test-task.sh                                   # selftests (schema negatives + live runs)
+```
+
+A run exits 0 only when its expectation is met (`expectExact` match); mismatches, nonzero agent exits, and timeouts record `status: failed` in `result.json` and exit 1. Each run gets a unique directory — rerunning never rewrites history.
+
+## Release model (M3)
+
+`RELEASE` single-sources the release version (0.0.X until declared stable); the image tag derives from it plus the pinned Pi version. Activation is health-gated and every event is recorded:
+
+```bash
+scripts/release.sh package                    # build + tag the release image
+scripts/release.sh activate                   # health check (exact marker) -> atomic pointer swap
+scripts/release.sh activate --fault-injection # prove the refusal path (drills only)
+scripts/release.sh rollback                   # health-gated return to the previous release
+scripts/release.sh status                     # release, tag, active pointer, recent log
+scripts/test-release.sh                       # release selftests
+```
+
+- `<dataRoot>/state/active.json` — the activation pointer (atomic tmp+rename replace)
+- `<dataRoot>/state/activation-log.jsonl` — append-only history: package / activate / refused / rollback
+
+A failed health check never activates; the previously active release remains deployed. Updating the software therefore cannot corrupt the running installation: package beside, gate, then flip. Verified by the update/refusal/rollback drills in BUILD-LOG Phase 7.
+
+## Runtime adapters (M4)
+
+The harness boundary is formalized: everything upstream (config, contracts, missions, tasks, run records) is harness-agnostic; everything inside an adapter belongs to one runtime.
+
+```text
+adapters/<name>/adapter.sh   env in: MOSAIC_SYSTEM_PROMPT_FILE, MOSAIC_REQUEST,
+                             MOSAIC_PROVIDER, MOSAIC_MODEL
+                             stdout: response only; stderr: diagnostics
+```
+
+- Selection: `execution.adapter` in config.json (optional; `pi` default; allowlist `pi`, `mock`)
+- `pi` — pinned Pi CLI, noninteractive print mode, ambient discovery off
+- `mock` — deterministic test adapter; never for real verification
+- Mission directives have a sanctioned injection point: when a task references a mission, the task runner mounts the run snapshot and the generated prompt gains a `MISSION (runtime)` section (objective + directives) after the four immutable contracts
+- Adding a harness (Claude, Codex, OpenCode) later means adding one directory — no orchestrator changes
+
+See `adapters/README.md` for the full contract.
+
+## Workspaces, capabilities, sessions (M5/M6)
+
+Optional task fields extend what an agent can do — all defaulting to the previous behavior:
+
+```json
+{
+  "workspace": "demo",                          // ":run" ephemeral, or persistent dataRoot/workspaces/<name>
+  "capabilities": { "tools": ["bash", "read"] }, // pi tool allowlist; absent = no tools
+  "session": "demo"                             // persistent session at dataRoot/sessions/<name>
+}
+```
+
+- The adapter runs inside the workspace; files it writes are host-visible (`dataRoot/workspaces/<name>`).
+- Sessions persist via pi's documented `--session-dir`; a follow-up run in the same session resumes the conversation (`-c`) and can recall prior context. Distinct names never share state. Ephemeral (`--no-session`) remains the default when no session is declared.
+- Selection authority: config for adapter/provider/model; the task file for workspace/capabilities/session.
+
+Inspect anything:
+
+```bash
+node scripts/mosaic-task.mjs list                # runs with task/workspace/session columns
+node scripts/mosaic-task.mjs show <runId>        # full record + snapshots + artifacts
+```
+
+Demo fixtures: `tasks/workspace-demo.json`, `tasks/session-demo-1.json` + `tasks/session-demo-2.json`.
+
+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 the release image (`mosaic-poc-agent:<pi>-r<release>`,
+   tag derived from `RELEASE` + the pinned Pi version) 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
+
+```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/run-task.sh    # run a mission/task file (see Missions & tasks)
+scripts/release.sh     # package / activate / rollback / status (see Release model)
+scripts/test-config.sh # fast config-layer selftests (no Docker)
+scripts/test-task.sh   # mission/task selftests (schema + adapter seam + live runs)
+scripts/test-release.sh # release selftests
+scripts/reset.sh       # delete the configured data root (safety-checked)
+```
+
+Prove the failure path (acceptance criterion 9):
+
+```bash
+EXPECTED_MARKER=MOSAIC_NOT_OK scripts/verify.sh   # must exit nonzero
+```
+
+## Authentication
+
+Pi's documented container authentication (see the package's
+`docs/containerization.md`) is used, in this order:
+
+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.
+
+Credentials are never committed, never copied into the image, and never printed.
+`.env.example` contains non-secret settings only.
+
+## Boundaries honored
+
+- No mounts of `~/.mosaic` or `~/.config/mosaic`; no Docker socket mount.
+- Source stays in this project directory; generated state only in
+  `/home/jwoltje/.mosaic-dev` (host) and `/var/lib/mosaic` (container).
+- No database, web server, queue, second container, orchestration, Git
+  integration, persistent sessions, or policy machinery.

+# Mosaic runtime adapters
+
+An adapter is the entire harness-specific surface of the system. Everything
+upstream of an adapter — configuration, contracts, missions, tasks, run
+records — is harness-agnostic; everything inside an adapter may assume one
+specific agent runtime.
+
+## Contract
+
+An adapter lives at:
+
+```text
+/opt/mosaic/adapters/<name>/adapter.sh
+```
+
+and must be executable. The dispatcher (`/opt/mosaic/src/run-agent.sh`)
+selects it via `MOSAIC_ADAPTER` (default: `pi`) and execs it after the
+system prompt has been generated.
+
+**Inputs (environment):**
+
+| Variable | Meaning |
+|---|---|
+| `MOSAIC_SYSTEM_PROMPT_FILE` | Absolute path to the generated system prompt (contracts + optional mission section). Read it; do not modify it. |
+| `MOSAIC_REQUEST` | The exact user request text (may contain newlines). |
+| `MOSAIC_PROVIDER` | Configured provider name. |
+| `MOSAIC_MODEL` | Configured model id. |
+
+Optional, adapter-specific (documented per adapter):
+
+| Variable | Meaning |
+|---|---|
+| `MOSAIC_MOCK_RESPONSE` | mock only: the verbatim response to emit |
+
+**Outputs:**
+
+- `stdout`: the model response text — the only channel the orchestrator captures
+- `stderr`: diagnostics (never credentials)
+- exit `0`: success; nonzero: failure
+
+## Rules
+
+1. Adapters print ONLY the response on stdout. Status lines go to stderr.
+2. Adapters never read configuration files; the resolved settings arrive via environment.
+3. Adapters never write outside `/var/lib/mosaic`.
+4. Adding an adapter requires: a new directory, the contract implementation, and
+   adding the name to the allowlist in `scripts/mosaic-config.mjs`.
+
+## Included adapters
+
+- `pi` — the pinned `@earendil-works/pi-coding-agent` CLI in noninteractive
+  print mode (`-p`), ambient discovery disabled, stdin detached.
+- `mock` — deterministic echo of `MOSAIC_MOCK_RESPONSE`. Test-only: never use
+  it where a real model response is required.
