Caught by the new estate-wide context-sync-drift gate (infra, ADR-0019).
This repo's copy had diverged from the canonical established in dma-cli/
infra -- synced to it, dead Cursor/Aider artifacts removed (2026-09-01
harness decision), Taskfile's drift assertion narrowed to match, adapters
regenerated against the current canonical AGENT.md.

Changed:

D  .cursorrules
M  AGENTS.md
M  CLAUDE.md
M  Taskfile.yml

# Agent context — Mathias workspace
<!-- Canonical root context for all AI coding agents.
Lives at: ~/dev/.context/AGENT.md
Applies to every project under ~/dev/ unless overridden.
Run `task context:sync` from ~/dev/ to regenerate harness-specific files.
Project-level context in .context/PROJECT.md layers on top of this. -->
## Who I am
I'm Mathias, a digital product manager and technology consultant based in Sweden.
I build software, research emerging tech, and deliver consulting engagements
for clients under NDA. I work across AI/ML, financial automation, web applications,
and climate/sustainability tech.
## How I work with agents
- I think like a product manager — I care about *why* before *how*
- I want agents to be opinionated and push back, not just execute blindly
- I prefer concise responses; skip ceremony and get to the point
- When I say "build this", I mean production-quality with tests, not a demo
- Ask me before making irreversible changes or adding heavy dependencies
- I work with confidential client data — never send it to cloud APIs unless I explicitly say it's OK
## Behavior rules
These rules apply to every task across every project, regardless of harness.
0. **Pre-task ritual — before ANY implementation (non-negotiable).** Run this before writing a single line:
- **Query the brain** (`brain_query`) for the domain + symptom. If the result changes your approach, surface it before acting. 5 seconds beats 5 hours.
- **Load the relevant skill** — see trigger table in *Engineering Skills* below.
- **Write the failing test first.** Name the test before the function. If the target is untestable (e.g. `main()` wiring), extract the logic into a testable function first. No implementation without a red test.
- **State the observable success criterion** — what specific behavior, output, or passing test proves this is done?
**TDD is non-negotiable.** "Tests pass" is not proof of correctness — only proof the tests ran. Write tests that would catch the bug before writing code that fixes it.
1. **No assumptions.** Don't hide confusion — surface it. Surface tradeoffs explicitly.
Think before coding; if the problem is unclear, ask or state assumptions before acting.
2. **Minimum viable code.** Solve with the smallest change that works. Nothing
speculative, no "while we're here" cleanups, no premature abstractions. Simplicity first.
3. **Surgical changes.** Touch only what the task requires. Leave unrelated code,
files, and formatting alone. Diffs should be small and reviewable.
4. **Goal-driven execution.** Define clear success criteria up front for every task.
Loop — implement, verify, refine — until those criteria are met. Don't claim
completion without evidence (tests pass, command output, observed behavior).
5. **Trunk-Based Development — commit directly to main.** Every commit is one
logical change (one tool, one fix, one test) with passing tests. Main is always
deployable. Never create long-lived feature branches.
**Exception — parallel agents on same repo:** If another agent is known to be
actively working on the same repo simultaneously, create a short-lived branch
(`agent/<description>`), finish the task, and merge to main within the same
session. Do not leave agent branches open between sessions.
**Exception — external contributor or client four-eyes requirement:** Use
PR flow only when a human reviewer outside the project is required. Document
the reason in PROJECT.md.
6. **Close the loop — every substantive task ends with the same ritual.** Shipping
the code is not the end of the task; capturing it is. Run this unprompted:
- **Tag + bump SemVer** on the change (annotated tag; minor for a feature or
new/changed ADR, patch for a fix; docs in the same commit). Check the repo's
actual last tag — stated versions in docs drift stale.
- **Push** main and the tag (CI is the gate).
- **Persist generalizable learnings to the brain** (`brain_write`, wing/hall) —
the reusable patterns and the footguns that would bite anyone again, never
project status. See *Knowledge base — when to write* below.
- **File discovered-but-deferred work as tracker issues** on the project's own
repo — token-budget gaps, recorded ADR limitations, v2 follow-ups. Don't let
"out of scope, recorded" rot in a commit message; make it a ticket with a
source pointer.
- Surface the brain entries and issue numbers in the closing summary so the
trail is auditable.

Exploratory: Rust, Zig — I'll tell you when I want these.
## Code conventions
- **Go style**: golines, gofumpt, golangci-lint
- **Errors**: `fmt.Errorf("operation: %w", err)` — never naked, never log-and-return
- **Naming**: stdlib conventions, no stuttering
- **Architecture**: prefer stdlib over frameworks, constructor injection, env-var config parsed into typed structs
- **Git**: conventional commits (`feat:`, `fix:`, `chore:`), commit directly to main,
one logical change per commit, CI is the quality gate
- **Never**: long-lived feature branches, PRs for solo work, direct push without
passing `task check` locally first
- **Security**: no secrets in code, govulncheck before adding deps, SOPS for encrypted config
- **Dependencies**: prefer stdlib. testify, slog, templ, sqlc, google.golang.org/adk (agent projects only) are pre-approved; anything else needs justification in the commit message
## Secret handling (every harness, every command)
Tool output is persisted: terminal → `~/.claude/projects` transcripts →
claudewatcher → brain/wiki → gitea history. A secret printed once is
searchable forever, and clearing it means rotating the key. So:
1. **Never print, echo, log, or transform a secret to inspect it.** No
`base64`/`xxd`/`cat` of a key, and never pipe a secret through a transform
to defeat `op run`'s output masking (it masks raw values; base64 hides them
from the mask — that exact trick leaked a key on 2026-06-11).
2. **Secrets stay in the subprocess.** Reference them only as env vars consumed
*inside* `op run --env-file ~/.op-env -- <cmd>`. Never place a literal secret
in a command's argv (it lands in the tool call and the transcript).
3. **Existence check without revealing the value:** `[ -n "$X" ] && echo set` —
never `${X:-...}` (returns the value when set) and never echo a substring of it.
4. **Cross-host secrets:** run the secret-consuming command on the host that has
the secret; do not forward a raw key over ssh argv/stdout.
5. If a secret does leak into output, say so immediately and flag it for rotation —
don't bury it.
## Infrastructure
Three machines on Tailscale:
| Machine | Role | Key specs |
|---------|------|-----------|
| koala | GPU inference, heavy compute | RTX 5070, runs k3s + llama-swap + shared postgres18/pgvector |
| iguana | Services, builds | M2 Ultra Mac |
| flamingo | Daily driver, edge | Mac mini, ~/dev is here |
- **Model routing**: LiteLLM in front of llama-swap (local) + cloud APIs (when permitted)
- **Orchestration**: k3s cluster across all three machines
- **Networking**: Tailscale mesh
## Project landscape
All development repos live at `~/dev/` (softlink from `~/Documents/local-dev/`).
Organized in thematic folders:
| Folder | Focus | Count |
|--------|-------|-------|
| `GO/` | Go web frameworks, API integrations, learning projects | ~10 |
| `AI/` | ML research, AI frameworks (FinRL, DSPy, crawl4ai) | ~6 |
| `AGENTS/` | Autonomous agents, coding agents, MCP servers, infra | ~15 |
| `QKX/` | Invoice processing, financial automation, payment systems | ~13 |
| `XT/` | Climate data, sustainability (Klimatkollen, Garbo) | ~2 |
See `~/dev/PROJECT_SUMMARY.md` for detailed descriptions of each project.
### Key active projects
- **super-koala** (`AGENTS/`) — multi-component agent stack with LangGraph, DSPy, MCP
- **azure-tiger** (`QKX/`) — invoice extraction → ISO 20022 payment instructions
- **gocrwl** (`AGENTS/`) — Go web crawler with containerized deployment
- **koala-ai-stack** (`AGENTS/`) — local AI server infrastructure management
- **klimatkollen** (`XT/`) — Swedish municipal climate data platform
## Knowledge base — actively use it
A persistent brain (BM25 search + LLM-synthesised Q&A) survives across sessions,
hosts, and harnesses. It holds 100+ hard-won entries: infra incident postmortems,
Go pitfalls, framework gotchas, design principles, ADRs. **It is not optional
reference material — query it actively, not just when explicitly told.**
### When to query (treat as a reflex)
- **Before** starting a non-trivial task — search for prior art with the symptom
AND the system component ("how did we solve X in Y?"). 5 seconds beats 5 hours.
- **When debugging** — search for the error string, the stack frame, the affected
service. Past you may have already paid this tax.
- **Before adopting** a pattern, library, framework, or model name — check if it
was tried and rejected, or what the integration footguns are.
- **When making architectural decisions** — search for the domain + "ADR" or
"decision" to find prior reasoning before re-deriving it.
- **When a recommendation feels novel** — challenge yourself: "has this been
documented?" The brain often has it.
### When to write
After you discover something that **future-you would forget** and that **isn't
recoverable from the code, git log, or PR description alone**:
- Bugs whose root cause is non-obvious and generalisable beyond this project.
- Framework / library / model-name quirks that bit you and would bite anyone.
- Design principles validated under fire (e.g. "every `_get` needs a `_list`").
- Postmortems for incidents: what broke, why, how diagnosed, what to do next time.
DON'T write project status, sprint progress, PR summaries, or "what I did this
session" — those rot fast and the originals are in git/gitea anyway. Brain
entries that age well are about *why*, *how to avoid*, and *what to do when*.
### How to access (per harness)
| Harness | Query | Write |
|---------|-------|-------|
| **Claude Code, Claude Desktop** | `brain_query` (BM25), `brain_answer` (LLM-synth + sources) MCP tools | `brain_write` MCP tool |
| **Crush, Pi, Antigravity, other MCP-capable** | same MCP server: `ingestion-brain` (via the `mcp__*_brain__*` namespace once authenticated) | same |
| **Anything HTTP-only (curl, scripts)** | `POST https://brain-mcp.d-ma.be/query` with `{"query":"..."}` (auth via `BRAIN_MCP_TOKEN`) | `POST .../write` with `{"content":"...","filename":"..."}` |
| **Browser / human inspection** | `https://git.d-ma.be/mathias/hyperguild` → `knowledge/` and `wiki/` markdown files |
- **Scoping**: defaults to `public` collection; client projects filter to `{client}` + `public`.
- **Routing**: brain_answer's LLM uses berget.ai as primary, iguana ollama as
fallback. Both are configurable in the `supervisor/ingestion-deployment.yaml`
on the koala k3s cluster; don't hardcode local-only model names into the
berget URL (see knowledge entry on namespace mismatches).
### Quick reflex checks
If you find yourself about to say any of these out loud, you owe yourself a brain query first:
- "I think the issue might be..."
- "Let me try X and see..."
- "I'll just write a script to..."
- "This is probably a new bug..."
- "Has anyone done this before?" — *yes, probably, go check.*
## Client work rules
When working on a project tagged with a client name:
1. Never send code, data, or context to cloud APIs — use local models only
2. Never reference other client projects or their data
3. Keep all artifacts within the client's git org / directory
4. Treat everything as confidential unless told otherwise
## Harness-agnostic principles
This context is designed to work with any AI coding tool:
- Claude Code, Cursor, Aider, Open WebUI, Charmbracelet Mods/Crush
- Pi Coding Agent, Mistral Vibe, Antigravity
- Any tool that accepts a system prompt or reads a markdown context file
The canonical source is always `.context/AGENT.md` (root) and `.context/PROJECT.md` (per-project).
Derived files are committed (see *How context propagates* below) so a `git pull` on any host yields full agent context with no setup.
## How context propagates
Canonical sources of truth:
- Universal: `~/dev/.context/AGENT.md` (this file)
- Project: `<repo>/.context/PROJECT.md` (per-repo)
Derived files (committed, regenerated by `task context:sync`):
- `CLAUDE.md`, `AGENTS.md`, `.cursorrules`, `.aider.conventions.md`,
`.context/system-prompt.txt`
Workflow:
1. Edit a canonical file. Run `task context:sync`. Commit canonical and
derived together. Push.
2. On any other host, `git pull` brings both. Claude Code (tree-walking)
uses `CLAUDE.md`; Crush / Pi / Antigravity (cwd-only) use `AGENTS.md`;
Cursor uses `.cursorrules`; Aider uses `.aider.conventions.md`.
3. `task check` runs `context:sync` then asserts `git status --porcelain`
is empty over the derived files (catches both modified-tracked drift
and missing-untracked adapters). A drift fails the check with a
message telling you to stage the regenerated files.
Behavior rules in this file and per-project rules in `PROJECT.md` apply
unconditionally on every host, every harness.
## Engineering Skills
Shared engineering skills live in the **`mathias/skills`** repo (`git.d-ma.be/mathias/skills`). Clone it to `~/dev/skills/` and run `SKILLS_CHECKOUT_DIR="$PWD" bash install.sh` there to wire every skill into your harnesses (Claude Code, Crush, Antigravity, Mistral Vibe) as native, on-demand skills. (Use `install.sh`, not `task install` — the latter is currently broken, skills#7.) Load at task start — not "on demand" but on schedule, before writing code. Browse `~/dev/skills/SKILLS_INDEX.md` for the full list.
**Skill trigger table — load before starting, not after getting stuck:**
| Task type | Load |
|-----------|------|
| Any feature or bug fix | `tdd` |
| Refactor or design | `clean-code` or `solid` |
| Debug | `problem-analysis` |
| Review code or PRs | `code-review` |
| Frame a problem before coding | `problem-analysis` |

# cad-atlas
## Identity
- **Name**: cad-atlas
- **Owner**: Mathias
- **Client**: personal
- **Repo**: git.d-ma.be/mathias/cad-atlas
- **Status**: active
- **Stack**: Go + Templ + HTMX + CDN Tailwind (template-go-web). Cross-project conventions: `~/dev/.context/AGENT.md`.
## What this is
A visual **atlas of the Continuous Agentic Development (CAD) workflow** — the full path
from a captured signal to a deployed k3s pod, one screen, reel-style ("From Signal to Pod").
It exists to (a) make the homelab's agentic delivery pipeline legible to a human, and
(b) render the CAD **audit chain** — which doubles as the regulated-industry audit artifact.
> **Core thesis:** the CAD audit chain *is* the visualization data.
> `TELOS → goal → spec → issue → execution → attestation → deploy` is both the trace and
> the audit package. Phase C renders it once and serves two masters (observability + compliance).
## Phases
- **Phase A — static hero viz** (current). Self-contained `internal/web/static/cad-atlas.html`,
data-driven from a hand-authored `STAGES` array (ground-truth snapshot from brain, 2026-07-19).
Served at `/` by `internal/web/handler.go` via `go:embed`. Reel-parity: SVG spine with
arrowheads, animated pulse, dashed **feedback bus** (stage 08 → TELOS), replay + slow-mo.
- **Phase B — generated-from-source**. Parse brain docs + `.gitea/workflows` + infra manifests
→ render the graph so it can't drift from config.
- **Phase C — live trace viewer**. Replace the static `STAGES` array with live reads of the
`assessor-loop` attestation ledger + brain `session_log` + Gitea run API + Flux events.
This is the prize: a real signal→pod trace viewer that is also the audit package.
## The workflow it visualizes (9 stages)
`00 Signals` (Applied AI Radar → mathias/signals) → `01 TELOS` (intention substrate) →
`02 Strategic session` (claude.ai frontier + LLM Council + Autoresearch Council) →
`03 Spec → Gitea issue` (agent-ready contract; Ed25519 admission #36; **var-go Oath**) →
`04 Human dispatch gate` (the only checkpoint; session-dispatch bridge → cad-dispatch.yml) →
`05 Execute · agentsquad` (serve/taskqueue, exec+review loop, risk LOW/MED/HIGH, dma-cli routing,
assessor-loop ledger) → `06 PR → CI` (go test/vet/lint/govulncheck + **var-go/oath gate**) →
`07 CD → pod` (Flux GitOps → k3s on koala) → `08 Loop back` (outcome scored vs TELOS goal).
### Three orthogonal governance gates
| Gate | Guards | Where |
|---|---|---|
| Ed25519 admission controller (#36) | spec **integrity** (issue untampered) | stage 03 |
| dispatch-allow (`.dispatch-allow` + `mathias/dispatch` allowlist) | repo **eligibility** (may agents run here) | stage 04/05 |
| **var-go Oath** (`cmd/vargo-gate`, commit status `var-go/oath`) | output **correctness** (PR satisfies the Oath; floor over reviewer, anti-rubber-stamp #55) | stage 06 |
## Dogfooding
This repo is built *through* the workflow it depicts. It is `dispatch-allow`-enabled, and its
own build increments are governed by a **var-go Oath** embedded in their spec issues (see the
Stage-03 tracking issue). Bootstrapping honesty (per swedsl honest-stub discipline): the Oath is
**defined** but `cmd/vargo-gate` is **not yet wired** into this repo's CI — until it is, the Oath
is advisory here. Wiring it is a first tracked task; disclosed in code, this doc, and CI config.

## Deploy note
CD (`.gitea/workflows/cd.yml`) deploys to k3s namespace `cad-atlas` via Flux. Per the known
template-go-agent CD gap: the `deploy` job stays RED until `mathias/infra` has
`k3s/apps/cad-atlas/deployment.yaml`. `check` + `build` are the real bootstrap gate.

Every gap, caveat, risk, open question and next step must land in one of four
places before the turn ends: **the brain**, **a repo** (code, docs, ADR),
**a tracker issue**, or **a plan file**. A finding stated only in conversation is
lost the moment the session closes — and this estate has repeatedly proved that a
remembered convention is an unreliable control.
This applies hardest to what is tempting to leave as a closing remark: "worth
knowing X isn't enforced yet", "this is a convention, not a gate", "we should
revisit Y". Those are exactly the items that need a locator. If it is worth
saying in a summary, it is worth writing where it can be found again without you.
## CAD sprint patterns
Two CAD sprint archetypes (defs: brain `wiki/homelab/decisions/continuous-agentic-development-cad-concept-2026-06-16`):
- **Inception Sprint** — birth a new repo. Oath-gated close; tag only once every clause holds. Brain: `.../inception-sprint-and-oath`.
- **Sweep Sprint** — clear an existing backlog. Parallel read-only research per issue → sequential one-issue-per-commit execution. Brain: `.../sweep-sprint-and-oath`.
Shared: decisions that are yours, not the agent's, surface as `DECISION NEEDED` (question/options/recommendation/blocks) — ask live if you're present, else comment and wait, never act past it. Live-breaking regressions get `git revert`, never forward-fixed; host-network work skips even read-only research (solo, synchronous, you present). Rule 6's closing ritual only fires once every Oath clause genuinely holds — blocked = descoped-and-tracked, never marked done.

Project-level context in .context/PROJECT.md layers on top of this. -->
## Who I am
I'm Mathias, a digital product manager and technology consultant based in Sweden.
I build software, research emerging tech, and deliver consulting engagements
for clients under NDA. I work across AI/ML, financial automation, web applications,
and climate/sustainability tech.
## How I work with agents
- I think like a product manager — I care about *why* before *how*
- I want agents to be opinionated and push back, not just execute blindly
- I prefer concise responses; skip ceremony and get to the point
- When I say "build this", I mean production-quality with tests, not a demo
- Ask me before making irreversible changes or adding heavy dependencies
- I work with confidential client data — never send it to cloud APIs unless I explicitly say it's OK
## Behavior rules
These rules apply to every task across every project, regardless of harness.
0. **Pre-task ritual — before ANY implementation (non-negotiable).** Run this before writing a single line:
- **Query the brain** (`brain_query`) for the domain + symptom. If the result changes your approach, surface it before acting. 5 seconds beats 5 hours.
- **Load the relevant skill** — see trigger table in *Engineering Skills* below.
- **Write the failing test first.** Name the test before the function. If the target is untestable (e.g. `main()` wiring), extract the logic into a testable function first. No implementation without a red test.
- **State the observable success criterion** — what specific behavior, output, or passing test proves this is done?
**TDD is non-negotiable.** "Tests pass" is not proof of correctness — only proof the tests ran. Write tests that would catch the bug before writing code that fixes it.
1. **No assumptions.** Don't hide confusion — surface it. Surface tradeoffs explicitly.
Think before coding; if the problem is unclear, ask or state assumptions before acting.
2. **Minimum viable code.** Solve with the smallest change that works. Nothing
speculative, no "while we're here" cleanups, no premature abstractions. Simplicity first.
3. **Surgical changes.** Touch only what the task requires. Leave unrelated code,
files, and formatting alone. Diffs should be small and reviewable.
4. **Goal-driven execution.** Define clear success criteria up front for every task.
Loop — implement, verify, refine — until those criteria are met. Don't claim
completion without evidence (tests pass, command output, observed behavior).
5. **Trunk-Based Development — commit directly to main.** Every commit is one
logical change (one tool, one fix, one test) with passing tests. Main is always
deployable. Never create long-lived feature branches.
**Exception — parallel agents on same repo:** If another agent is known to be
actively working on the same repo simultaneously, create a short-lived branch
(`agent/<description>`), finish the task, and merge to main within the same
session. Do not leave agent branches open between sessions.
**Exception — external contributor or client four-eyes requirement:** Use
PR flow only when a human reviewer outside the project is required. Document
the reason in PROJECT.md.
6. **Close the loop — every substantive task ends with the same ritual.** Shipping
the code is not the end of the task; capturing it is. Run this unprompted:
- **Tag + bump SemVer** on the change (annotated tag; minor for a feature or
new/changed ADR, patch for a fix; docs in the same commit). Check the repo's
actual last tag — stated versions in docs drift stale.
- **Push** main and the tag (CI is the gate).
- **Persist generalizable learnings to the brain** (`brain_write`, wing/hall) —
the reusable patterns and the footguns that would bite anyone again, never
project status. See *Knowledge base — when to write* below.
- **File discovered-but-deferred work as tracker issues** on the project's own
repo — token-budget gaps, recorded ADR limitations, v2 follow-ups. Don't let
"out of scope, recorded" rot in a commit message; make it a ticket with a
source pointer.
- Surface the brain entries and issue numbers in the closing summary so the
trail is auditable.
## Default stack
| Layer | Default | Fallback | Last resort |
|-------|---------|----------|-------------|
| Language | Go | Python | TypeScript, Java, C |
| UI | HTMX + Templ | Server-rendered HTML | React (only if SPA is justified) |
| Build | Task (taskfile.dev) | Make | — |
| Containers | Docker Compose (dev), k3s (prod) | — | — |
| DB | PostgreSQL + sqlc | SQLite | — |
| Search | pgvector (vector), BM25 | Qdrant (when >1M vectors or hybrid retrieval) | — |
| Logging | slog (structured) | — | — |
| Testing | Table-driven, testify | — | — |
| Agents (Go) | google.golang.org/adk + pkg/litellm adapter | — | — |
Exploratory: Rust, Zig — I'll tell you when I want these.
## Code conventions
- **Go style**: golines, gofumpt, golangci-lint
- **Errors**: `fmt.Errorf("operation: %w", err)` — never naked, never log-and-return
- **Naming**: stdlib conventions, no stuttering
- **Architecture**: prefer stdlib over frameworks, constructor injection, env-var config parsed into typed structs
- **Git**: conventional commits (`feat:`, `fix:`, `chore:`), commit directly to main,
one logical change per commit, CI is the quality gate
- **Never**: long-lived feature branches, PRs for solo work, direct push without
passing `task check` locally first
- **Security**: no secrets in code, govulncheck before adding deps, SOPS for encrypted config
- **Dependencies**: prefer stdlib. testify, slog, templ, sqlc, google.golang.org/adk (agent projects only) are pre-approved; anything else needs justification in the commit message
## Secret handling (every harness, every command)
Tool output is persisted: terminal → `~/.claude/projects` transcripts →
claudewatcher → brain/wiki → gitea history. A secret printed once is
searchable forever, and clearing it means rotating the key. So:
1. **Never print, echo, log, or transform a secret to inspect it.** No
`base64`/`xxd`/`cat` of a key, and never pipe a secret through a transform
to defeat `op run`'s output masking (it masks raw values; base64 hides them
from the mask — that exact trick leaked a key on 2026-06-11).
2. **Secrets stay in the subprocess.** Reference them only as env vars consumed
*inside* `op run --env-file ~/.op-env -- <cmd>`. Never place a literal secret
in a command's argv (it lands in the tool call and the transcript).
3. **Existence check without revealing the value:** `[ -n "$X" ] && echo set` —
never `${X:-...}` (returns the value when set) and never echo a substring of it.
4. **Cross-host secrets:** run the secret-consuming command on the host that has
the secret; do not forward a raw key over ssh argv/stdout.
5. If a secret does leak into output, say so immediately and flag it for rotation —
don't bury it.
## Infrastructure
Three machines on Tailscale:
| Machine | Role | Key specs |
|---------|------|-----------|
| koala | GPU inference, heavy compute | RTX 5070, runs k3s + llama-swap + shared postgres18/pgvector |
| iguana | Services, builds | M2 Ultra Mac |
| flamingo | Daily driver, edge | Mac mini, ~/dev is here |
- **Model routing**: LiteLLM in front of llama-swap (local) + cloud APIs (when permitted)
- **Orchestration**: k3s cluster across all three machines
- **Networking**: Tailscale mesh
## Project landscape
All development repos live at `~/dev/` (softlink from `~/Documents/local-dev/`).
Organized in thematic folders:
| Folder | Focus | Count |
|--------|-------|-------|
| `GO/` | Go web frameworks, API integrations, learning projects | ~10 |
| `AI/` | ML research, AI frameworks (FinRL, DSPy, crawl4ai) | ~6 |
| `AGENTS/` | Autonomous agents, coding agents, MCP servers, infra | ~15 |
| `QKX/` | Invoice processing, financial automation, payment systems | ~13 |
| `XT/` | Climate data, sustainability (Klimatkollen, Garbo) | ~2 |
See `~/dev/PROJECT_SUMMARY.md` for detailed descriptions of each project.
### Key active projects
- **super-koala** (`AGENTS/`) — multi-component agent stack with LangGraph, DSPy, MCP
- **azure-tiger** (`QKX/`) — invoice extraction → ISO 20022 payment instructions
- **gocrwl** (`AGENTS/`) — Go web crawler with containerized deployment
- **koala-ai-stack** (`AGENTS/`) — local AI server infrastructure management
- **klimatkollen** (`XT/`) — Swedish municipal climate data platform
## Knowledge base — actively use it
A persistent brain (BM25 search + LLM-synthesised Q&A) survives across sessions,
hosts, and harnesses. It holds 100+ hard-won entries: infra incident postmortems,
Go pitfalls, framework gotchas, design principles, ADRs. **It is not optional
reference material — query it actively, not just when explicitly told.**
### When to query (treat as a reflex)
- **Before** starting a non-trivial task — search for prior art with the symptom
AND the system component ("how did we solve X in Y?"). 5 seconds beats 5 hours.
- **When debugging** — search for the error string, the stack frame, the affected
service. Past you may have already paid this tax.
- **Before adopting** a pattern, library, framework, or model name — check if it
was tried and rejected, or what the integration footguns are.
- **When making architectural decisions** — search for the domain + "ADR" or
"decision" to find prior reasoning before re-deriving it.
- **When a recommendation feels novel** — challenge yourself: "has this been
documented?" The brain often has it.
### When to write
After you discover something that **future-you would forget** and that **isn't
recoverable from the code, git log, or PR description alone**:
- Bugs whose root cause is non-obvious and generalisable beyond this project.
- Framework / library / model-name quirks that bit you and would bite anyone.
- Design principles validated under fire (e.g. "every `_get` needs a `_list`").
- Postmortems for incidents: what broke, why, how diagnosed, what to do next time.
DON'T write project status, sprint progress, PR summaries, or "what I did this
session" — those rot fast and the originals are in git/gitea anyway. Brain
entries that age well are about *why*, *how to avoid*, and *what to do when*.
### How to access (per harness)
| Harness | Query | Write |
|---------|-------|-------|
| **Claude Code, Claude Desktop** | `brain_query` (BM25), `brain_answer` (LLM-synth + sources) MCP tools | `brain_write` MCP tool |
| **Crush, Pi, Antigravity, other MCP-capable** | same MCP server: `ingestion-brain` (via the `mcp__*_brain__*` namespace once authenticated) | same |
| **Anything HTTP-only (curl, scripts)** | `POST https://brain-mcp.d-ma.be/query` with `{"query":"..."}` (auth via `BRAIN_MCP_TOKEN`) | `POST .../write` with `{"content":"...","filename":"..."}` |
| **Browser / human inspection** | `https://git.d-ma.be/mathias/hyperguild` → `knowledge/` and `wiki/` markdown files |
- **Scoping**: defaults to `public` collection; client projects filter to `{client}` + `public`.
- **Routing**: brain_answer's LLM uses berget.ai as primary, iguana ollama as
fallback. Both are configurable in the `supervisor/ingestion-deployment.yaml`
on the koala k3s cluster; don't hardcode local-only model names into the
berget URL (see knowledge entry on namespace mismatches).
### Quick reflex checks
If you find yourself about to say any of these out loud, you owe yourself a brain query first:
- "I think the issue might be..."
- "Let me try X and see..."
- "I'll just write a script to..."
- "This is probably a new bug..."
- "Has anyone done this before?" — *yes, probably, go check.*
## Client work rules
When working on a project tagged with a client name:
1. Never send code, data, or context to cloud APIs — use local models only
2. Never reference other client projects or their data
3. Keep all artifacts within the client's git org / directory
4. Treat everything as confidential unless told otherwise
## Harness-agnostic principles
This context is designed to work with any AI coding tool:
- Claude Code, Cursor, Aider, Open WebUI, Charmbracelet Mods/Crush
- Pi Coding Agent, Mistral Vibe, Antigravity
- Any tool that accepts a system prompt or reads a markdown context file
The canonical source is always `.context/AGENT.md` (root) and `.context/PROJECT.md` (per-project).
Derived files are committed (see *How context propagates* below) so a `git pull` on any host yields full agent context with no setup.
## How context propagates
Canonical sources of truth:
- Universal: `~/dev/.context/AGENT.md` (this file)
- Project: `<repo>/.context/PROJECT.md` (per-repo)
Derived files (committed, regenerated by `task context:sync`):
- `CLAUDE.md`, `AGENTS.md`, `.cursorrules`, `.aider.conventions.md`,
`.context/system-prompt.txt`
Workflow:
1. Edit a canonical file. Run `task context:sync`. Commit canonical and
derived together. Push.
2. On any other host, `git pull` brings both. Claude Code (tree-walking)
uses `CLAUDE.md`; Crush / Pi / Antigravity (cwd-only) use `AGENTS.md`;
Cursor uses `.cursorrules`; Aider uses `.aider.conventions.md`.
3. `task check` runs `context:sync` then asserts `git status --porcelain`
is empty over the derived files (catches both modified-tracked drift
and missing-untracked adapters). A drift fails the check with a
message telling you to stage the regenerated files.
Behavior rules in this file and per-project rules in `PROJECT.md` apply
unconditionally on every host, every harness.
## Engineering Skills
Shared engineering skills live in the **`mathias/skills`** repo (`git.d-ma.be/mathias/skills`). Clone it to `~/dev/skills/` and run `SKILLS_CHECKOUT_DIR="$PWD" bash install.sh` there to wire every skill into your harnesses (Claude Code, Crush, Antigravity, Mistral Vibe) as native, on-demand skills. (Use `install.sh`, not `task install` — the latter is currently broken, skills#7.) Load at task start — not "on demand" but on schedule, before writing code. Browse `~/dev/skills/SKILLS_INDEX.md` for the full list.

# cad-atlas
## Identity
- **Name**: cad-atlas
- **Owner**: Mathias
- **Client**: personal
- **Repo**: git.d-ma.be/mathias/cad-atlas
- **Status**: active
- **Stack**: Go + Templ + HTMX + CDN Tailwind (template-go-web). Cross-project conventions: `~/dev/.context/AGENT.md`.
## What this is
A visual **atlas of the Continuous Agentic Development (CAD) workflow** — the full path
from a captured signal to a deployed k3s pod, one screen, reel-style ("From Signal to Pod").
It exists to (a) make the homelab's agentic delivery pipeline legible to a human, and
(b) render the CAD **audit chain** — which doubles as the regulated-industry audit artifact.
> **Core thesis:** the CAD audit chain *is* the visualization data.
> `TELOS → goal → spec → issue → execution → attestation → deploy` is both the trace and
> the audit package. Phase C renders it once and serves two masters (observability + compliance).
## Phases
- **Phase A — static hero viz** (current). Self-contained `internal/web/static/cad-atlas.html`,
data-driven from a hand-authored `STAGES` array (ground-truth snapshot from brain, 2026-07-19).
Served at `/` by `internal/web/handler.go` via `go:embed`. Reel-parity: SVG spine with
arrowheads, animated pulse, dashed **feedback bus** (stage 08 → TELOS), replay + slow-mo.
- **Phase B — generated-from-source**. Parse brain docs + `.gitea/workflows` + infra manifests
→ render the graph so it can't drift from config.
- **Phase C — live trace viewer**. Replace the static `STAGES` array with live reads of the
`assessor-loop` attestation ledger + brain `session_log` + Gitea run API + Flux events.
This is the prize: a real signal→pod trace viewer that is also the audit package.
## The workflow it visualizes (9 stages)
`00 Signals` (Applied AI Radar → mathias/signals) → `01 TELOS` (intention substrate) →
`02 Strategic session` (claude.ai frontier + LLM Council + Autoresearch Council) →
`03 Spec → Gitea issue` (agent-ready contract; Ed25519 admission #36; **var-go Oath**) →
`04 Human dispatch gate` (the only checkpoint; session-dispatch bridge → cad-dispatch.yml) →
`05 Execute · agentsquad` (serve/taskqueue, exec+review loop, risk LOW/MED/HIGH, dma-cli routing,
assessor-loop ledger) → `06 PR → CI` (go test/vet/lint/govulncheck + **var-go/oath gate**) →
`07 CD → pod` (Flux GitOps → k3s on koala) → `08 Loop back` (outcome scored vs TELOS goal).
### Three orthogonal governance gates
| Gate | Guards | Where |
|---|---|---|
| Ed25519 admission controller (#36) | spec **integrity** (issue untampered) | stage 03 |
| dispatch-allow (`.dispatch-allow` + `mathias/dispatch` allowlist) | repo **eligibility** (may agents run here) | stage 04/05 |
| **var-go Oath** (`cmd/vargo-gate`, commit status `var-go/oath`) | output **correctness** (PR satisfies the Oath; floor over reviewer, anti-rubber-stamp #55) | stage 06 |
## Dogfooding
This repo is built *through* the workflow it depicts. It is `dispatch-allow`-enabled, and its
own build increments are governed by a **var-go Oath** embedded in their spec issues (see the
Stage-03 tracking issue). Bootstrapping honesty (per swedsl honest-stub discipline): the Oath is
**defined** but `cmd/vargo-gate` is **not yet wired** into this repo's CI — until it is, the Oath
is advisory here. Wiring it is a first tracked task; disclosed in code, this doc, and CI config.

## Deploy note
CD (`.gitea/workflows/cd.yml`) deploys to k3s namespace `cad-atlas` via Flux. Per the known
template-go-agent CD gap: the `deploy` job stays RED until `mathias/infra` has
`k3s/apps/cad-atlas/deployment.yaml`. `check` + `build` are the real bootstrap gate.

**Chat is not a durable store. Never rely on Mathias remembering anything.**
Every gap, caveat, risk, open question and next step must land in one of four
places before the turn ends: **the brain**, **a repo** (code, docs, ADR),
**a tracker issue**, or **a plan file**. A finding stated only in conversation is
lost the moment the session closes — and this estate has repeatedly proved that a
remembered convention is an unreliable control.
This applies hardest to what is tempting to leave as a closing remark: "worth
knowing X isn't enforced yet", "this is a convention, not a gate", "we should
revisit Y". Those are exactly the items that need a locator. If it is worth
saying in a summary, it is worth writing where it can be found again without you.
## CAD sprint patterns
Two CAD sprint archetypes (defs: brain `wiki/homelab/decisions/continuous-agentic-development-cad-concept-2026-06-16`):
- **Inception Sprint** — birth a new repo. Oath-gated close; tag only once every clause holds. Brain: `.../inception-sprint-and-oath`.
- **Sweep Sprint** — clear an existing backlog. Parallel read-only research per issue → sequential one-issue-per-commit execution. Brain: `.../sweep-sprint-and-oath`.
Shared: decisions that are yours, not the agent's, surface as `DECISION NEEDED` (question/options/recommendation/blocks) — ask live if you're present, else comment and wait, never act past it. Live-breaking regressions get `git revert`, never forward-fixed; host-network work skips even read-only research (solo, synchronous, you present). Rule 6's closing ritual only fires once every Oath clause genuinely holds — blocked = descoped-and-tracked, never marked done.

2. On any other host, `git pull` brings both. Claude Code (tree-walking)

Cursor uses `.cursorrules`; Aider uses `.aider.conventions.md`.
2. On any other host, `git pull` brings both. Which file a harness reads does
NOT split cleanly by lookup strategy, so do not reason from the strategy:
- `CLAUDE.md` — Claude Code (walks up the tree)
- `AGENTS.md` — Crush, Pi, Antigravity (cwd-only), OpenCode (project root,
global at `~/.config/opencode/AGENTS.md`), and Mistral Vibe, which **walks
up** from cwd and takes the first `AGENTS.md` it finds
(user-level `~/.vibe/AGENTS.md`)
- `.context/system-prompt.txt` — Open WebUI, Mods, raw API calls; not read by
any harness, it is for pasting
Vibe tree-walks for `AGENTS.md`, so "tree-walkers use CLAUDE.md" is false.
Each repo's `AGENTS.md` embeds the canonical and is the first one found from
inside that repo, so this works — but by construction, not by luck.

Shared engineering skills live in the **`mathias/skills`** repo (`git.d-ma.be/mathias/skills`). Clone it to `~/dev/skills/` and run `SKILLS_CHECKOUT_DIR="$PWD" bash install.sh` there to wire every skill into your harnesses (Claude Code, Crush, Antigravity, Mistral Vibe) as native, on-demand skills. (Use `install.sh`, not `task install` — the latter is currently broken, skills#7.) Load at task start — not "on demand" but on schedule, before writing code.

**Claude Code** installs the repo as a plugin from the marketplace the same repo hosts. That path also carries the `secret-guard` and `pre-task-ritual` hooks and the brain/gitea/infra MCP servers, which symlinks cannot:
```
/plugin marketplace add https://git.d-ma.be/mathias/skills.git
/plugin install skills@mathias
```
Skills are **namespaced** under Claude Code: load `tdd` as `skills:tdd`. The trigger table below uses bare names — prefix them.
**Crush, Pi and OpenCode** have no plugin system and are wired by `install.sh` as one directory symlink per harness via `~/.agents/skills`. Do not clone the checkout into `~/dev`: that folder is iCloud-shared between the Macs and spans two path roots (`/Users/mathias` vs `/home/mathias` on koala), so a checkout there is a git working tree with two concurrent writers, and any absolute symlink stored in it is broken on one side by construction (skills#23). Leave `SKILLS_CHECKOUT_DIR` at its host-local default.
Check a host with `task doctor` in the skills repo; it also runs automatically at session start via the plugin.
