From 5dfd2c0f7edc62510dd073246ddb1534523a7163 Mon Sep 17 00:00:00 2001 From: Mathias Date: Thu, 8 Oct 2026 08:34:50 +0200 Subject: [PATCH] docs: main is protected, ship by PR (local-dev#42) Gitea will refuse direct pushes to main in this repo. Rule 5's reviewed lane was enforced on the merge tools (tbd_ship / pr_merge, gitea-mcp v0.17.0/v0.18.0) but not on a direct commit; this overrides rule 5's "risk/low straight to main" for this repo and says why. Derived adapter files regenerated where the repo has them.

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. - -7. **Finish what's closable — only involve me for a genuine call.** If a - tracker issue, PR, or checklist item is demonstrably resolved — the fix - landed, the state changed, you verified it live — close/merge/check it off - in the same turn. Don't leave it open "for the record" or park it waiting - on me to confirm something that already happened; that's bookkeeping, not - a decision. Reserve asking me (`AskUserQuestion`, a `DECISION NEEDED` - comment, or otherwise pausing) for when it's genuinely mine to call: - irreversible or prod/host-impacting actions, a real judgment call with no - clearly-better option, ambiguous intent, or anything secret-writes/ - destructive-git already gate. Before claiming something is closable, - verify it live (re-check the issue, re-run the command) rather than - trusting your own earlier summary (brain: `filed-issue-not-same-as-fixed`). - -8. **Control code needs an adversary, not a checklist.** Code whose job is to - refuse, deny, gate or contain is not adequately verified by a green gate. - Rule 5 makes CI the quality gate and that holds for ordinary work — but a - passing suite only asserts what its author already thought of, and for a - control the author is precisely the person whose imagination just failed. - Measured on `dispatch#75`: five review rounds, five real escapes verified by - execution, and **CI was green on every one of them** while `git rm - ././.dispatch-allow` deleted the file the control existed to protect. So - route this work through a review with authority to block, instructed to - verify by execution rather than by reading the implementation. Expect to be - blocked more than once; that is the control working, not the reviewer being - difficult. (brain: `a-green-gate-is-not-evidence-for-control-code`; the - practices live in the `pr-gatekeeper` agent.) - -9. **A test's name must not claim more than its assertions prove.** Name a test - after the mechanism it observes, not the goal it serves. - `DoesNotInheritEnv` is honest; `IsContained` is a claim the test cannot - support. This is not pedantry about naming — when name and assertion - diverge, the name wins in the reader's head and the gap becomes invisible, - which is what lets the defect survive review. Found three times in one PR, - twice in tests written to fix the previous instance of it; each passed while - the thing it was named for was exploitable. If you cannot name the mechanism, - you do not yet know what the test observes. - -## 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.

This mirrors - the tiered merge model in `assessor-loop` - `method/transfer-to-a-regulated-organisation.md` §4.1, so the estate practises - what it sells instead of merging everything on green and claiming otherwise. - - **Concurrency is NOT a reason to branch.** Measured 2026-08-29 across three real - collisions between parallel sessions: two were not branching problems at all — a - generated artifact written to the same path by both (branching turns that into a - merge conflict on a 33k-line JSON), and uncommitted work in a shared checkout - (a per-session worktree fixes it) — and the third was an ordinary non-fast-forward - push resolved by rebase in seconds. Use a worktree per session on shared repos and - timestamp generated artifacts. Do not reach for a branch. - - Branch+PR flow carries documented costs on solo repos: merging auto-closes gated - issues, review comments live on a thread separate from the issue's, and a - merged-and-deleted branch cannot be amended (brain: - `gitea-pr-merge-autoclose-and-review-comment-footguns`). Those are the price of - the `risk/medium`+ lane — paid deliberately, not incurred by accident. - - **Exception — external contributor or client four-eyes requirement:** Use PR flow - when a human reviewer outside the project is required. Document the reason in - PROJECT.md. - - **Exception — a GitOps repo where a branch cannot be reconciled.** In a repo whose - deployment watches one branch (`mathias/infra`: Flux watches `main`), a branch is - invisible to the thing that applies it. A `risk/medium` change to `alerts.yaml` or - `litellm-config.yaml` can be linted on a branch but never *exercised* there, so a - PR would buy a review of a state that was never deployed. - - There, `risk/medium`+ work stays on `main` and instead requires a **recorded - adversarial review pass before the push** — `skills:pr-gatekeeper` or equivalent, - reviewing the staged diff. **The reviewer's verdict goes in the issue, not a PR - thread.** No verdict recorded means the lane was not used, and saying "the gate was - green" is not the same claim. - - Be honest about what this is: a recorded *independent* pass, not four-eyes in the - sense `assessor-loop` §4.1 means for a regulated organisation, because the reviewer - is an agent. It is more than the repo had and less than the model it mirrors; do not - describe it as the stronger property. (infra#470, decided 2026-09-29.) - - This lane depends on the `risk/` label being right. A label that triggers a heavier - lane is load-bearing, not cosmetic — if work that belongs in it is unlabelled, the - lane silently does not apply. - -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. - - **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. - -7. **Finish what's closable — only involve me for a genuine call.** If a - tracker issue, PR, or checklist item is demonstrably resolved — the fix - landed, the state changed, you verified it live — close/merge/check it off - in the same turn. Don't leave it open "for the record" or park it waiting - on me to confirm something that already happened; that's bookkeeping, not - a decision. Reserve asking me (`AskUserQuestion`, a `DECISION NEEDED` - comment, or otherwise pausing) for when it's genuinely mine to call: - irreversible or prod/host-impacting actions, a real judgment call with no - clearly-better option, ambiguous intent, or anything secret-writes/ - destructive-git already gate. Before claiming something is closable, - verify it live (re-check the issue, re-run the command) rather than - trusting your own earlier summary (brain: `filed-issue-not-same-as-fixed`). - -8. **Control code needs an adversary, not a checklist.** Code whose job is to - refuse, deny, gate or contain is not adequately verified by a green gate. - Rule 5 makes CI the quality gate and that holds for ordinary work — but a - passing suite only asserts what its author already thought of, and for a - control the author is precisely the person whose imagination just failed. - Measured on `dispatch#75`: five review rounds, five real escapes verified by - execution, and **CI was green on every one of them** while `git rm - ././.dispatch-allow` deleted the file the control existed to protect. So - route this work through a review with authority to block, instructed to - verify by execution rather than by reading the implementation. Expect to be - blocked more than once; that is the control working, not the reviewer being - difficult. (brain: `a-green-gate-is-not-evidence-for-control-code`; the - practices live in the `pr-gatekeeper` agent.) - -9. **A test's name must not claim more than its assertions prove.** Name a test - after the mechanism it observes, not the goal it serves. - `DoesNotInheritEnv` is honest; `IsContained` is a claim the test cannot - support. This is not pedantry about naming — when name and assertion - diverge, the name wins in the reader's head and the gap becomes invisible, - which is what lets the defect survive review. Found three times in one PR, - twice in tests written to fix the previous instance of it; each passed while - the thing it was named for was exploitable. If you cannot name the mechanism, - you do not yet know what the test observes. - -## 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. - -## 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) | stdlib `logging` w/ structured `extra=` (or structlog) | — | -| 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 -- **Python style** (fallback language): ruff (format+lint, one tool), mypy --strict (non-negotiable, - matches Go's static typing discipline), pytest + pytest-cov (table-driven via - `@pytest.mark.parametrize`), uv (venv+deps+lock, one tool), pydantic-settings (typed env-var config - — same principle as Go's typed structs), src-layout + `pyproject.toml` only (no `setup.py`) -- **Errors**: `fmt.Errorf("operation: %w", err)` — never naked, never log-and-return. - Python: `raise X from e` (exception chaining, same principle) — never bare `except`, never silent `pass` -- **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.
