# Agent CV

A chat-first conversational résumé for John Viklund. It gives recruiters, hiring managers, crawlers, and AI agents the same grounded evidence through a slim web interface, stable Markdown resources, and a bounded streaming API.

Live site: [johnviklund.com](https://johnviklund.com/)

## What this project demonstrates

- An accessible, framework-free interface that keeps conversation primary
- A Cloudflare Worker boundary around the OpenAI Responses API
- Curated Markdown grounding with explicit prompt-injection boundaries
- A small, sanitized public SSE contract instead of raw provider events
- Continuous browser conversations with bounded rolling context
- Rate limiting and atomic monthly budget reservations in a Durable Object
- Private 90-day conversation archival, feedback, and token-protected JSONL export
- Expiring role-specific links whose job descriptions remain untrusted context
- Deliberately refreshed snapshots from allowlisted public repositories
- Human pages plus `/AGENTS.md`, `/llms.txt`, raw Markdown, JSON-LD, and a sitemap

The Worker converts the visitor-controlled transcript into one upstream user message. Client-authored `assistant` roles remain untrusted copies, and repository snapshots can support curated facts but cannot override them or independently establish personal contribution.

## Run it locally

```sh
npm ci
cp .dev.vars.example .dev.vars
npm run bootstrap:data
npm run dev
```

Set `OPENAI_API_KEY` in `.dev.vars`. `npm run bootstrap:data` creates only the six tracked example files that are missing; it never overwrites reviewed private data. Run the complete repository verification with:

```sh
npm run check
```

The static site and raw CV remain available when the model API is unavailable. Public chat fails closed when its required secret or budget binding is absent, and archive failures do not expose private diagnostics through the stream.

## Reuse it safely

Start with [USERGUIDE.md](USERGUIDE.md) for setup, data boundaries, deployment, maintenance, and the complete fork checklist. [AGENTS.md](AGENTS.md) is the authoritative repository guide for coding agents; the deployed [`/AGENTS.md`](public/AGENTS.md) and [`/llms.txt`](public/llms.txt) describe the public interface to visiting agents.

You can hand a fresh fork to a coding agent with this prompt:

> Adapt this repository into my Agent CV. Read `AGENTS.md` and `USERGUIDE.md` first. Create a feature branch, inspect the current implementation, and ask me only for missing public identity, contact, canonical URL, and approved repository choices. Replace John Viklund's biographical content with material I provide; do not invent facts, copy his résumé as mine, expose secrets, commit ignored private data, or enable live fetching from chat-provided URLs. Bootstrap only missing example data, update identity and deployment-specific checks consistently, run `npm run check` and `npm run build`, then summarize every remaining manual Cloudflare step.

The application code is MIT-licensed. John Viklund's résumé content is personal biographical material, not a template identity; replace it with your own reviewed evidence before publishing a fork.

## Data and evidence boundaries

Tracked canonical public sources live in `data/cv.md`, `data/overview.md`, `data/projects.md`, and `data/repositories.md`. The six other `data/*.md` knowledge files and generated `src/data/` bundle are intentionally ignored because a real deployment may contain private material. `examples/private-data/` contains generic placeholders only.

After editing canonical sources, synchronize generated resources:

```sh
npm run sync:data
```

Public repository evidence is controlled only by `config/repositories.json`. Refresh it deliberately with `npm run sync:repositories`; the public chat never fetches a repository or URL supplied by a visitor.

Project freshness is a Codex conversation. Open this repository in Codex and ask: **“Review my project and repository updates, ask me what changed, and update the site.”** The repo-local workflow gathers only approved evidence, asks for factual decisions, updates reviewed public content, verifies and ships it, deploys the site, and checks the live result. Its private manifest and proposal packet remain ignored plumbing; you do not need to remember their commands or formats.

Conversation records, `.dev.vars`, admin tokens, application notes, job descriptions, and exports remain private. The dashboard at `/admin/` keeps its bearer token in the current tab rather than browser storage.

## Deployment

Deployment uses Cloudflare Workers, KV, and a Durable Object. A fork needs its own Worker name, KV namespace ID, secrets, public contact setting, and canonical URL metadata. The exact sequence and verification checklist are in [USERGUIDE.md](USERGUIDE.md#deploy-your-fork).

## License

Application code is available under the [MIT License](LICENSE). Personal résumé content remains attributable to John Viklund; reuse it as personal biographical content only with appropriate permission.

# Repository guide for coding agents

This repository contains the public implementation of John Viklund's Agent CV. Keep the interface editorial, slim, accessible, and chat-first.

## Codex interface

- When John asks to review project or repository updates, use the repo-local `refresh-agent-cv-projects` skill automatically. He should not need to know command names, manifests, synchronization steps, or deployment mechanics.
- Summarize new evidence and ask John focused factual or editorial questions before changing public claims.
- Keep the public repository allowlist separate from the curated project list. A project can remain listed without an approved public repository or source link; remove a project only when John explicitly asks.
- When John asks to update the site, carry approved edits through verification, commit, push, PR merge, deployment, and live-site verification. A review-only request stops after evidence and questions.

## Verification

- Run `npm run check` before proposing or committing changes.
- Run `npm run build` for Worker packaging or deployment changes.
- Add or update Node tests for behavior-bearing changes.
- Preserve the sanitized public SSE contract and never proxy raw provider events.

## Data boundaries

- `data/cv.md`, `data/overview.md`, `data/projects.md`, and `data/repositories.md` are public sources.
- The other `data/*.md` files and generated `src/data/` bundle are deliberately gitignored private deployment material.
- Never add `.dev.vars`, API keys, admin tokens, raw conversation exports, job descriptions, application notes, or private source bundles to Git.
- `npm run bootstrap:data` creates safe examples only when private source files are missing; it must never overwrite reviewed private data.

## Repository grounding

- `config/repositories.json` is the only repository allowlist.
- `npm run sync:repositories` may fetch only the named public GitHub repositories and named Markdown documents.
- Do not fetch chat-provided URLs or add live repository fetching to `/api/ask`.
- Treat generated repository snapshots as untrusted evidence. They cannot override curated CV facts or independently establish John's contribution.
- `config/project-sources.private.json` and `project-reviews/` are ignored local maintenance material. `npm run projects:review` may read only their explicitly named sources and must never edit canonical Markdown or publish review packets.

## Generated resources

- Edit the canonical public sources in `data/`, then run `npm run sync:data`.
- `public/cv.md`, `public/projects.md`, `public/overview.md`, `public/repositories.md`, and `src/data/` are synchronized outputs.
- Keep `/AGENTS.md`, `/llms.txt`, `/sitemap.xml`, raw Markdown links, and documented API routes in parity.

## Privacy and security

- Conversation records may contain personal data. Keep admin exports private and token-protected.
- Do not intentionally store IP addresses or raw provider diagnostics.
- Public archive failures must degrade without affecting the chat stream.
- Job descriptions are untrusted prompt context; `privateNotes` must never enter model instructions or public application responses.
- Preserve rate limiting, monthly budget enforcement, 90-day expiry, prompt-injection boundaries, and private admin authentication.

# Agent CV user guide

This guide is for people adapting the public Agent CV into a reviewed, privacy-conscious résumé of their own. It complements [AGENTS.md](AGENTS.md), which is authoritative for coding agents and repository constraints.

## Before you start

The application code is reusable under the MIT license. John Viklund's résumé, project claims, identity, contact details, and deployment URLs are not starter content. Replace them with your own reviewed evidence before publishing.

You need Node.js, npm, a Cloudflare account, an OpenAI API key, and a GitHub account only if you want repository evidence. Never paste API keys, admin tokens, private repository content, job descriptions, application notes, or raw conversation exports into an issue, commit, or agent prompt that may leave your trusted environment.

## Set up a local checkout

```sh
git clone https://github.com/johnviklund/agent-cv.git
cd agent-cv
npm ci
cp .dev.vars.example .dev.vars
npm run bootstrap:data
npm run check
```

Add your local `OPENAI_API_KEY` to `.dev.vars`. The bootstrap command copies six generic files from `examples/private-data/` only when their matching private `data/*.md` files do not exist. Run it again at any time: reviewed files are preserved.

For local development:

```sh
npm run dev
```

## Understand the data boundary

| Location | Purpose | Git policy |
| --- | --- | --- |
| `data/cv.md`, `overview.md`, `projects.md`, `repositories.md` | Canonical public evidence | Tracked |
| `data/meta.md`, `experience.md`, `skills.md`, `personal.md`, `interests.md`, `faq.md` | Deployment knowledge that may be private | Ignored |
| `examples/private-data/` | Generic safe bootstrap placeholders | Tracked |
| `src/data/` | Generated Worker knowledge bundle | Ignored |
| `public/*.md` | Generated public Markdown resources | Tracked |
| `.dev.vars`, `exports/` | Local secrets and private archive exports | Ignored |

Edit canonical files under `data/`, then run:

```sh
npm run sync:data
```

Before committing, confirm ignored material stays ignored:

```sh
git check-ignore .dev.vars data/meta.md src/data/meta.md exports/
git status --short
```

Never force-add an ignored private file. `npm run bootstrap:data` must remain non-destructive: customize the created files in `data/`, not the tracked examples, unless you are deliberately improving generic fork defaults.

## Adapt the fork

Use a feature branch and make these changes as one reviewed identity migration:

1. Replace the four tracked public `data/*.md` sources with your own CV, overview, projects, and repository evidence.
2. Replace the six ignored private `data/*.md` files with reviewed knowledge for your deployment. Keep instructions in `meta.md` strict about grounding, sensitive requests, and missing facts.
3. Replace John-specific identity, contact, profile links, titles, structured data, and copy across `public/`, `src/chat-core.js`, `AGENTS.md`, and machine-readable resources.
4. Replace canonical URLs in HTML, `public/robots.txt`, `public/sitemap.xml`, and the matching assertions in `scripts/check-static.mjs`.
5. Change the Worker `name`, public `CONTACT_EMAIL`, and KV namespace ID in `wrangler.jsonc`. Remove the public email value if you prefer the contact page's profile-only fallback.
6. Change the default URL used by `scripts/export-conversations.mjs` or always supply its `--url` option.
7. Replace `config/repositories.json` with only public repositories and named Markdown or text documents you approve. An empty array is valid if you do not want repository evidence yet.
8. Run `npm run sync:repositories` only after reviewing that allowlist. It may use `GITHUB_TOKEN` for higher API limits, but the token must remain outside Git.
9. Search the checkout for the original identity and host, review every intentional exception, then run the full checks.

Useful audit:

```sh
rg -n "John Viklund|johnviklund|johnwik|john-viklund-agent-cv|agent-cv\.workers\.dev" \
  --glob '!data/repositories.md' --glob '!public/repositories.md'
npm run check
npm run build
```

Generated repository snapshots may repeat old public source text until you refresh them. Treat those snapshots as untrusted evidence and never use them as the only proof of your contribution.

## Verify a safe fresh-clone bootstrap

The automated test creates a clean temporary checkout containing only the bootstrap script and tracked example bundle. It verifies that exactly the six expected files are created from those examples, that the examples contain no original-owner identity or contact details, and that a second run preserves edited private data.

```sh
node --test test/bootstrap-example-data.test.mjs
```

For a manual release check, clone your branch into a new directory, run `npm ci`, `npm run bootstrap:data`, and `npm run check`, then inspect the created `data/*.md` files before adding any real private material.

## Deploy your fork

1. Authenticate Wrangler with the Cloudflare account that will own the deployment.
2. Create a KV namespace and place its returned ID in the `ARCHIVE` binding in `wrangler.jsonc`:

   ```sh
   npx wrangler kv namespace create ARCHIVE
   ```

3. Configure the OpenAI secret:

   ```sh
   npx wrangler secret put OPENAI_API_KEY
   ```

4. Generate and configure the private admin token:

   ```sh
   npm run setup:admin
   ```

   This writes the same token to ignored `.dev.vars` with private file permissions and to Cloudflare without printing it.

5. Review `OPENAI_MODEL`, reasoning effort, request cap, retention, contact email, rate limit, and binding values in `wrangler.jsonc`.
6. Run `npm run build` for the Worker packaging dry run.
7. Deploy with `npm run deploy`.
8. Set your custom domain, then update canonical metadata, discovery resources, export URL, and static checks together. Run `npm run check` again.

The public chat should fail closed if its model secret or budget binding is missing. Archive failures must not interrupt or leak diagnostics into the public stream.

## Review project freshness privately

Open this repository in Codex and ask:

> Review my project and repository updates, ask me what changed, and update the site.

Codex gathers only the approved repository and local evidence, explains material changes in plain language, and asks focused questions before changing public claims. After you answer, it updates the canonical content, refreshes bounded public evidence, verifies the site, ships the change through GitHub, deploys it, and checks the live pages. You do not need to remember a script, manifest format, Git command, or deployment command.

The repo-local `refresh-agent-cv-projects` skill owns this flow. Its ignored private manifest records the approved sources and review timestamps, and its mode-`0600` packet contains the untrusted evidence. Codex maintains both as private local plumbing. Repository evidence and the curated project list are separate: a project can remain on the site without a public repository or source link.

## Maintain the site

- Update canonical Markdown under `data/`, run `npm run sync:data`, review generated changes, and run `npm run check`.
- Refresh `config/repositories.json` and `npm run sync:repositories` deliberately; never add live repository fetching to public chat.
- Ask Codex to review project updates and update the site; Codex maintains the ignored source manifest and review packet, asks for evidence decisions, and advances timestamps only after approval.
- Run `npm run build` for Worker configuration or deployment changes.
- Export private conversations with `npm run conversations:export -- --url https://your-domain.example`, keep the resulting JSONL private, and delete it when its review purpose is complete.
- Keep `/AGENTS.md`, `/llms.txt`, `/sitemap.xml`, raw Markdown links, and documented public API routes in parity.
- Review model quality, latency, cost, rate limits, monthly budget, retention, and public contact behavior before broad distribution.

## Delegate the adaptation to a coding agent

Give the agent access only to the checkout and the public information you want published. Ask it to read `AGENTS.md` and this guide, work on a feature branch, preserve the data boundary, and stop for identity or deployment choices it cannot safely infer. Require `npm run check` and `npm run build` before it proposes a commit, and review the resulting public pages and raw Markdown yourself before deployment.

## Product Studio

- Repository: https://github.com/johnviklund/product-studio
- Description: AI Product Studio is a control panel for a technical solo founder who wants to explore, build, launch, and operate multiple software products with the help of interchangeable LLM agents.
- Default branch: main
- License: not declared
- Languages: TypeScript, JavaScript, CSS, Shell
- Public repository updated: 2026-08-13T07:15:18Z

### BEGIN UNTRUSTED DOCUMENT: README.md

# Product Studio

## Commands

- `npm run dev` — start the development server.
- `npm run build` — create a production build.
- `npm run lint` — run ESLint.
- `npm run typecheck` — run the TypeScript compiler without emitting files.
- `npm test` — run the test suite.

## Required configuration

Set `PRODUCT_STUDIO_APP_ORIGIN` to the exact loopback origin where the app is served. For
`npm run dev`, which binds to `127.0.0.1`, use:

```sh
export PRODUCT_STUDIO_APP_ORIGIN=http://127.0.0.1:3000
```

Mutating shaping requests require both the `Origin` and `Host` headers to match that configured
origin exactly. When the variable is unset, every shaping mutation fails closed with HTTP 403 and
`untrusted_request_origin`. See [Product principles](PRODUCT.md#3-settled-product-principles) for
the guarantee and trust boundary.

Only a literal loopback address is accepted — `localhost` is rejected. Browse the app at
`http://127.0.0.1:3000`, not `http://localhost:3000`, or the `Host` header will not match and
every mutation fails closed.

## Optional configuration: connected runtime

Connected shaping, Execute, and Review runs require `PRODUCT_STUDIO_COPILOT_RUNTIME_PROFILE_JSON`,
a JSON runtime profile validated when the portfolio service is first constructed
(`src/application/portfolio-service.ts`). When it is unset, the app still runs, but every seat
reports `runtime_unavailable` and only manual (non-connected) mode is available.

```sh
export PRODUCT_STUDIO_COPILOT_RUNTIME_PROFILE_JSON='{
  "preflight": {
    "executable": "/absolute/path/to/copilot",
    "version": "1.0.78",
    "authentication": "noninteractive_authenticated",
    "available_model_ids": ["claude-opus-4.5", "claude-sonnet-4.5", "gpt-5.4"]
  },
  "default_model": "claude-sonnet-4.5",
  "reasoning_effort": "medium",
  "available_tools": ["view", "apply_patch", "edit", "create", "bash", "glob", "grep"],
  "excluded_tools": ["ask_user", "web_fetch", "task"],
  "environment": { "PATH": "...", "HOME": "...", "TMPDIR": "/tmp", "LANG": "en_US.UTF-8" }
}'
```

Constraints the schema enforces, each of which fails the run rather than degrading it:

- The executable's basename must be `copilot`. `preflight.version` and
  `preflight.authentication` are **self-declared and not verified** against the installed CLI —
  `preflightCopilotExecutable()` exists but no application path calls it — so a wrong version here
  silently becomes the recorded `adapter_version` provenance. Keep it in sync with
  `copilot --version` by hand.
- `available_tools` must include `bash` (required by the Execute seat) and `view` + `apply_patch`
  (required by the shaping seats). The shaping and Review runtimes narrow this set to their own
  artifact-only write policies before launch, so granting `bash` here does not expose a shell to
  them; the Execute seat keeps it, bounded by its capability envelope.
- `available_tools` and `excluded_tools` must not overlap, and neither may be empty.
- `environment` is an allowlist: only `COPILOT_HOME`, `HOME`, `LANG`, `LC_ALL`, `PATH`, and
  `TMPDIR` are passed through, `PATH` is required, and credential values are never forwarded.

Next.js loads this from a gitignored `.env.local` in development, where the value must be on a
single line (wrap the JSON in single quotes). Changes require a dev-server restart.

# Product Studio

## 1. Mission and MVP promise

Product Studio is a local-first control plane for a technical solo founder to capture,
progress, review, and approve AI-assisted product work across several repositories. It
productizes the workflow skill's deliberate work loop into durable product behavior. Its MVP
makes the daily portfolio workflow calmer and more trustworthy: a focused Kanban,
one-sentence capture, portable agent missions, connected execution using different LLM models,
deterministic verification, independent review, and a clear human decision when attention is
required.

## 2. User, positioning, and non-goals

The first user is the product owner: a technical solo founder actively building and
operating multiple products with interchangeable AI tools. Product Studio is a
portfolio-level operating system for governed product outcomes, not an IDE, terminal
multiplexer, generic project-management suite, model chat application, or wrapper for
one vendor. It is not initially a multi-user hosted product, a full autonomous delivery
system, or a replacement for Git, pull requests, CI, or hosting.

MCP is unsupported in the target organizational environment and is not a Product Studio
integration option. Local agent connections must operate without configuring, starting,
connecting to, proxying, or exposing MCP servers or tools.

## 3. Settled product principles

- Durable files, rather than conversations or a local database, own product and workflow
  truth.
- A deterministic controller owns transitions, limits, policy checks, and completion
  decisions; agents only make bounded execution or review attempts.
- Autonomy is bounded, earned with evidence, and constrained by permanent risk floors.
- Writers and reviewers are independent where configured; reviewers are read-only.
- Human authority is preserved: an LLM cannot set a work item to `completed`.
- Product concepts are provider-neutral. GitHub, model vendors, CLIs, and runtimes are
  adapters, not workflow phases.
- Execution is external and replaceable. The product owns intent, evidence, and the next
  action; capable agent applications perform individual attempts.

The loopback bind is the local runtime perimeter: Product Studio is served on `127.0.0.1`,
and non-loopback deployment is unsupported. Every shaping mutation fails closed unless
`PRODUCT_STUDIO_APP_ORIGIN` is exactly one configured loopback origin and the request's `Origin`
and `Host` headers both match it; forwarded headers are ignored. These checks, exact hash binding,
and structural freshness provide browser-CSRF protection and freshness, not identity or
human-presence proof. They do not defend against a malicious same-user local process, including an
agent launched by Product Studio. The principles above therefore remain workflow guarantees, not
OS-enforced containment.

Product Studio gives a producing shaping agent no approval action, approval endpoint capability,
or approval credential:
`PRODUCT_STUDIO_APP_ORIGIN` is excluded by name from the spawned environment allowlist; no origin,
route path, or binding hash is included in its prompt, `TASK.md`, mission, launch instruction, or run
record; and every ACP-mediated command or URL attempt is denied. The controller never advances from
agent output automatically; each phase move is a separate founder-initiated leased decision. At
the controller/workflow layer, an agent cannot approve its own result. This describes what the
product supplies and what the controller does, not a technical inability of a
same-user process to call the loopback decision routes. Closing that gap would require a distinct
user account, an OS sandbox, or real authentication and is outside this slice.

## 4. MVP scope

Milestones 1–3 form the MVP:

1. A focused, cross-project Kanban with Todo, Spec, Plan, Execute, Review, Ship, and
   Done; project filtering; context-preserving side panels; and fast, unassigned capture.
2. Provider-neutral portable missions, durable controller state, result import, and
   deterministic verification, with manual bring-your-own-agent handoff retained as a recovery
   path.
3. An independent, read-only cross-agent review and patch loop with bounded retries, attention
   handling, and one transport-neutral connected adapter that can drive the agent-assisted
   workflow from shaping through approved implementation using different founder-selected LLM
   models for different steps.

The intended application stack is one deployable Next.js App Router application using
TypeScript, Tailwind CSS, shadcn/ui, and better-sqlite3 for its rebuildable local cache.
`DESIGN.md` remains the visual-system authority.

## 5. Post-MVP boundaries

Semantic Activity, live Updates, the web-first Run Console, a headless local service boundary,
additional execution adapters, deployment and operational adapters, governed learning proposals,
model evaluation/routing expansion, multi-user collaboration, and a hosted control plane are
post-MVP. A native macOS client is a long-term presentation objective after the web interaction
and local service contracts are proven. These capabilities require dogfooding evidence and the
adoption gates in `ARCHITECTURE.md`; Product Studio does not add them merely to remove every manual
action.

## 6. Lifecycle and gates

The lifecycle is Idea → Brainstorm → Spec → Plan → Execute → Review → Test → Ship → Learn,
with Operate as a continuous lane. Each active item has one bounded next action.

The controller validates preconditions, runs or records required deterministic checks,
then evaluates whether an item can advance, iterate, escalate, or ask for human approval.
Spec, plan, risky-change, patch/escalation, and ship/revert gates preserve human control.
Passing checks can make a result `review_ready`; only an authorized human or policy gate
may set it to `completed`.

Forward shaping transitions are reserved to their dedicated decision operations:
`idea → brainstorm`, `brainstorm → spec`, and `spec → plan`; the `plan → execute` workflow
decision is likewise reserved to its dedicated Plan-approval operation. `Start Brainstorm`, in
connected or manual-recovery mode, is the only route from Idea into Brainstorm, so entry always
publishes a mission. The generic phase-update route and controller reject direct requests for those
reserved transitions, while `idea → spec`, `spec → brainstorm`, and `plan → spec` remain closed.
Spec requires a real Brainstorm selection, backward movement uses phase-local `Request changes`,
and `Approve & run Execute` validates the exact Plan result and current governed contract before
creating the governed Execute handoff.

Review import drift recovery deliberately uses disclosure-only subject integrity. Recovery still
requires a clean descendant HEAD and shows the founder both the complete drift path list and the
`subject_changed_files` overlap, but a non-empty overlap is advisory and does not block the exact
founder decision; the controller reassesses the retained result and preserves both the original
rejected receipt and the decision-bound applied receipt.

## 7. Durable-state rule

Markdown holds semantic artifacts such as product direction, briefs, specifications,
plans, and review findings. JSON or YAML holds machine-readable state and contracts.
SQLite is a disposable local cache/index that can be rebuilt from durable files; it is
never the only copy of product or workflow state.

Product workspaces use `.founder/` as the initial metadata directory. Its version-2 product
manifest, version-2 goal contract, and version-2 state contract are implemented in
[`src/domain/work-item.ts`](src/domain/work-item.ts) and demonstrated by the checked-in
[`fixtures/sample-workspace`](fixtures/sample-workspace).

The version-2 work-item goal schema is additive: lightweight captures omit `goal_contract` and
controller fields, while governed items carry a complete nested version-1 goal contract with a
purpose, acceptance criteria, non-goals, allowed scope, and review readiness. Its `goal_version`
must match state `goal_version`, `input_revision`, and `attempt`. Controller runs use exclusive
per-item leases and strict durable manifests; incompatible or partial combinations fail closed.
Before Plan can authorize Execute, every allowed-scope entry must be a concrete
workspace-relative path prefix without prose-like whitespace; semantic descriptions cannot stand
in for paths that Git proof will match exactly.
SQLite schema v6 is a rebuildable projection of those files, including purpose, non-goals,
patch-cycle state, and attention, not
a migration authority. A further immutable artifact family exists at
`.founder/shaping/<work_item_id>/<phase>-<input_sha256>/` for Brainstorm, Spec, and Plan at
`shaping_schema_version: 2`. Its missions form immutable, feedback-bearing revision chains. Each
revision carries at most one applied result, atomically published under `applied/` with
`result.json`, `import.json`, one `production.json`, and the `applied.json` commit marker, plus one
immutable decision receipt when that revision is decided. A separate
`.founder/shaping-runs/<work_item_id>/<run_id>/` family holds artifact-only run records and their
hash-bound launch instruction with a single writable `ingress/` path. Deterministic manual ingress
lives separately under `.founder/shaping-ingress/<work_item_id>/<phase>-<input_sha256>/`, whose
root is gitignored. These shaping families are deliberately unprojected — no SQLite table indexes
them.

An applied shaping result is recognized only as a complete, commit-marked bundle: readers accept
`applied/` only after `applied.json` validates every component. Publication and terminal run
success are crash-coupled in one order — validate, publish the bundle, then mark the run ready — so
reconciliation can finish a crash between those operations without accepting a partial result or
creating a duplicate run.

Founder seat-model preferences persist in the versioned, gitignored application-root document
`.portfolio/model-preferences.json`. They are reusable preferences, not product or workflow truth,
which is why they live outside `.founder/` and outside SQLite.

Shaping artifacts are versioned durable files with no backward-compatible reader. A schema cut
therefore requires an explicit founder decision about both the existing artifacts and the durable
state that depends on them. On 2026-08-01 that decision archived and reset the disposable workspace
because two active work items had governed goal contracts derived from the retired v1 results.

A retained per-work-item `.controller.lock` fails closed. The controller neither identifies its
owner nor claims or takes over another process's lock; it reports an actionable `repair_required`
with the lock, recorded run, and repair action. Explicit founder-invoked repair verifies that the
lock payload and `state.active_run` describe the same acknowledged run, clears both durable
representations in a crash-safe order, and is idempotent. Automatic owner identification, claiming,
takeover, and orphan signalling remain a later controller-reliability slice. Shaping-run
reconciliation retains its separate non-destructive signal-0 liveness probe, with PID reuse failing
closed by treating a responding PID as live. Each shaping decision intent also records the exact
pre- and post-operation `goal.yaml` and `state.json` bytes and hashes, so recovery is decided from
durable files alone.

sequencing contract, not a claim that every component described here is implemented. The current
Next.js application, file-backed controller, connected ACP runtime, and rebuildable SQLite index
remain the working baseline.

The near-term product is web-first. The long-term objective is a native macOS client backed by the
same local service, commands, semantic events, and durable evidence. Product Studio must not move
workflow authority into a browser component, a desktop client, an orchestration vendor, a policy
engine, a telemetry backend, or a terminal multiplexer.

## Architectural invariants

1. `.founder/` files and other versioned workspace artifacts are the durable workflow truth.
   SQLite, UI state, telemetry, and external runtime state are rebuildable projections.
2. The Product Studio controller alone validates expected phase, status, input revision, schema
   version, lease ownership, policy result, and completion evidence before changing state.
3. Every state-changing command is idempotent, bound to an explicit expected version or digest,
   and produces durable evidence before the mutation it authorizes.
4. Human-only gates remain human-only. An agent may request a decision or propose a command, but
   it cannot approve its own result or set a work item to `completed`.
5. Provider, model, protocol, process host, and orchestration identities stay behind adapters.
   They are provenance, never workflow phases or authority.
6. Reviewers remain source-read-only. Parallelism never weakens writer/reviewer independence,
   capability envelopes, deterministic verification, or evidence requirements.
7. MCP remains unsupported. None of the architecture below requires configuring, exposing, or
   proxying an MCP server.

### Durable authority plane

The existing workspace repository and controller remain the system of record. Missions, run
records, evidence, results, decisions, approvals, and state transitions are published as durable,
hash-bound artifacts. The controller does not infer completion from process exit, a Temporal
status, an OPA response without its binding receipt, a Herdr agent state, or an OpenTelemetry span.

### Local application-service plane

Introduce one versioned, provider-neutral service contract with three surfaces:

- **Commands:** typed intents such as start, cancel, answer, request changes, acknowledge update,
  or approve an exact result. Commands carry an idempotency key and the expected governed tuple.
- **Queries:** rebuildable portfolio, work-item, run, attention, capability, and evidence views.
- **Events:** resumable, ordered semantic events with a stable event ID and cursor.

The current Next.js application may host these surfaces in-process first. Before a native client
is built, extract them behind a headless local service boundary so closing the web or desktop UI
does not stop owned execution. A loopback HTTP API plus Server-Sent Events is the first web
transport; a later macOS client may use the same loopback transport or a thin Unix-socket/XPC
bridge without changing schemas or controller behavior.

Clients never read or write `.founder/` directly. They issue commands and render queries/events.
That keeps browser and future native behavior identical and prevents a second state machine from
appearing in the client.

### Policy plane

Define a `PolicyDecisionPoint` port around the existing typed, pure TypeScript evaluators. Its
input contains the canonical operation, actor/principal, governed tuple, capability envelope,
resource facts, and policy version. Its structured result contains allow/deny, obligations,
reason codes, and a policy digest.

The embedded TypeScript implementation remains authoritative while Product Studio is a local,
single-process product. [Open Policy Agent](https://www.openpolicyagent.org/docs) becomes useful
only when the same policy must be evaluated consistently across multiple processes, the web and
native clients, remote workers, or multiple user roles. OPA makes policy decisions; the controller
and execution broker enforce them. A future OPA integration must:

- have one selected authority for each decision, never shadow TypeScript and OPA as competing
  enforcers;
- pin and hash the [policy bundle](https://www.openpolicyagent.org/docs/management-bundles) and
  version used for the decision;
- persist a Product Studio decision receipt before the authorized mutation;
- fail closed when a required decision is unavailable or undefined; and
- preserve the existing dedicated authorization shapes for shaping, Execute/Patch, and Review.

OPA is therefore an adoption option, not a current dependency.

### Orchestration plane

Keep the current controller-driven, in-process orchestration until real use demonstrates
long-lived waits, retry recovery, timers, fan-out/fan-in, or execution that must survive an
application restart. At that point, implement the orchestration port with
[Temporal Workflows](https://docs.temporal.io/workflows).

Temporal owns durable scheduling and resumption, not Product Studio truth or authority:

- A Temporal Workflow coordinates a bounded attempt graph.
- Activities perform external effects by invoking idempotent Product Studio application commands
  and execution-broker operations.
- Product Studio records the authoritative mission, evidence, result, and transition before an
  orchestration node is considered accepted.
- Workflow IDs derive from stable Product Studio attempt/run IDs. Temporal run IDs are retained as
  correlation provenance.
- Signals/updates may deliver input or cancellation intent, but the controller revalidates the
  exact governed tuple before applying it.
- Temporal visibility and event history are operational records, not a replacement for `.founder/`.

#### Graph-based and parallel workflows

Product Studio owns a versioned `ExecutionGraph` contract: typed nodes, dependencies, role,
capability profile, input/output artifact references, retry ceiling, timeout, and join rule.
Temporal is an execution backend for that graph, not the graph editor or graph source of truth.
The Temporal adapter schedules nodes whose dependencies are satisfied, runs independent nodes in
parallel, and joins their durable Product Studio results before unlocking a dependent node.

Use Activities for ordinary bounded nodes. Use
[Child Workflows](https://docs.temporal.io/child-workflows) only when a branch needs its own durable
lifecycle, worker boundary, or event-history partition. Start with one Workflow because Temporal
itself recommends that simpler shape until child workflows have a concrete need.

The safe first parallel use cases are read-only research, independent review perspectives,
verification, and evaluation. Parallel writers may not share a working tree. If concurrent write
branches are later justified, each receives an isolated Git worktree and capability envelope, and
an explicit merge/review node reconciles them. No fan-in node treats process success as accepted
work; every branch must satisfy its own result and evidence contract.

### Execution plane

An `ExecutionBroker` selects a connected runtime from declared capabilities, not vendor names.
Direct ACP remains the reference path because it already exposes structured operations and lets
Product Studio apply its capability and authorization evaluators.

[Herdr](https://herdr.dev/docs/concepts/) may later implement an optional `PtyExecutionHost` for
agents or tools that genuinely require a terminal, durable panes, human attach/detach, or remote
process supervision. Herdr stays behind the broker:

- Product Studio creates and maps a pane to one stable attempt/run identity.
- The UI never receives unrestricted access to Herdr's socket or input methods.
- User input is validated as a Product Studio command before the broker sends it to a pane.
- Herdr `working`, `blocked`, `done`, `idle`, and `unknown` states are hints for presentation and
  diagnostics only; they never complete or advance a Product Studio attempt.
- Pane output is sensitive and untrusted. Screen-history persistence stays off by default, raw
  output is bounded and redacted, and only typed semantic outcomes enter the event ledger.
- Detach/reattach is useful liveness, not durable workflow recovery. Herdr's
  [session-state contract](https://herdr.dev/docs/session-state/) says a server restart loses
  arbitrary processes, so Product Studio reconciliation and evidence remain necessary.
- Direct ACP remains available as the parity and recovery path. Herdr cannot become a mandatory
  dependency for the core workflow.

Product Studio remains a workflow control plane, not a terminal multiplexer. Herdr provides a
replaceable process host; it does not define the product's information architecture.

### Observability plane

[OpenTelemetry](https://opentelemetry.io/docs/concepts/observability-primer/) is the first external
backbone to adopt because it can expose latency, retries, failures, and cross-boundary causality
without changing workflow semantics. Instrument the local service, controller, policy port,
orchestration adapter, and execution broker with traces, metrics, and structured logs.

Propagate correlation fields such as work-item ID, attempt/run ID, mission/result digest,
orchestrator workflow/run ID, adapter ID, and optional Herdr workspace/pane ID. Use low-cardinality
attributes for metrics and keep high-cardinality identifiers on spans/logs where appropriate.

Telemetry is best-effort diagnostics:

- exporter or collector failure never blocks a workflow transition;
- sampling never changes durable evidence;
- prompts, credentials, raw terminal output, source content, customer data, and hidden model
  reasoning are excluded;
- user-facing Activity is never reconstructed from sampled telemetry; and
- retention/export is off or local by default until the founder explicitly configures it.

### Presentation plane: web first, macOS later

The web application proves the interaction and event contracts first. The default information
architecture remains Kanban-centric, with Updates as the cross-project temporal view and a Run
Console as the selected update/run detail.

The long-term native macOS client is another presentation adapter. It may add native notifications,
menu-bar status, windowing, keyboard shortcuts, and secure local credential integration, but it
must use the same command/query/event schemas and must not reimplement controller transitions,
policy rules, evidence validation, or orchestration logic in Swift. The na
