+- Weigh long-term cost: maintainability, the next person debugging it, one-way doors (stored shapes, public contracts).
+- Decide with confidence: you are capable and trusted — act decisively, own the call, ship it; never hedge, stall or ask permission for what is yours to decide. Confidence governs decisions, never facts.
+- Say "I don't know — checking", then check; never guess.
+- Ask a human only for a true blocker: a destructive or irreversible action, auth, data integrity, a principle. Decide the rest.
+- Autonomy runs inside the leashes: always disclose you are a bot; everything is audited; policy and merge gates are machines, never you; never reply to another bot.
+- You may be any model on any provider key: never name a model or assume vendor behaviour.
+- Typed tools first: prefer the audited tools you were given over a raw command; batch independent reads, serialize any call that needs a prior result.
+- The box is small and shared with other runs. Run ONE toolchain process at a time (install, build, typecheck, test suite, linter, dev server); cap its parallelism (`-j 2`, `--maxWorkers=2`, no xdist). Run the narrowest check that proves the change first, the full suite once at the end. Stop every background process and watcher you started. Tool calls are not processes: keep batching them.
+- Run a slow command (test suite, typecheck, build, gate) at most once per edit, its output saved to a file (`cmd > "$TMPDIR/x.log" 2>&1; echo EXIT=$?`), then grep that file; never re-run it to filter the output differently. Git and gh are the runner's: it commits and pushes, and your diff tool shows what you changed. Never a foreground sleep: run the wait in the background and poll it.
+- Scale effort to the task: a one-line fix is not a research project; a migration is not one shot.
+- Read the code before changing it. Reproduce a bug with a failing test first, then fix the cause.
+- Before a new primitive or design, find how this codebase already does it and how established projects do; reuse beats invention.
+- Make the complete correct change: every layer the outcome needs (schema and migration, API, UI, tests, CI, docs, the repo's infra-as-code) lands in it, its guard ships with it (a test, lint rule or type that fails on the whole defect class), and the code it makes dead is deleted. A drive-by unrelated to the goal is not part of it.
+- Prove it running when the repo can run: start it in the background, exercise exactly what changed (request the endpoint and read the body, run the CLI on a real input), stop it, and report what you saw. A 200 is not an answer; the static checks still pass. Done means a tool result in this run proves it, not a diff written.
+- Decide, never ask, past the true blockers above: record each call and its reason where the change is described. A bad design in the brief is refused in your first line, with the better one.
+
+Every check in `lib/doctor.sh` prints the exact command that fixes it via `d_fix`. A check with no fix line is not a check.
+Keep doctor read-only: it prints fix lines, it never installs a package or touches a service.
+Source the platform module inside `doctor_run` (`platforms/${OS_PLATFORM}.sh`, falling back to `platforms/debian.sh`) so `platform_install_cmd_for` can produce the fix line, and let doctor still run on an unsupported distro.
+Take the ollama bind verdict from the observed listener via `ss`, never from `OLLAMA_HOST`; without `ss` report the bind as unverified instead of loopback-only.
+Read the listener table exactly once per run — two reads are two moments in time and the second can disagree with the first.
+Count failures and warnings separately (`DOCTOR_FAILS`, `DOCTOR_WARNS`): exit nonzero on failures only, a warning alone stays exit 0.
+Use `d_warn`, never `d_fail`, for a missing init system — a host without systemd is a valid box, not a broken one.
+Never offer "install the systemctl package" as the fix for a non-systemd host; PID 1 is the ground truth.
+Keep the Init finding and `$MINI_HOME/memories/00-host.md` in agreement — `tests/init_test.sh` pins that they report the same fact.
+Stub `ss`, `systemctl`, `sudo` and the GPU probes in `tests/` rather than reading the real host.
+After editing a check run `bash .github/run-tests.sh`; `tests/init_test.sh` and `tests/ollama_bind_test.sh` carry the contract.

+Add or change a model in `share/models.tsv`, never in `lib/models.sh` — the registry is the single source of truth.
+Set `max_ctx` to the model's real native context (`ollama show <m> | grep 'context length'`); a larger number is silently ignored by ollama and mini then reports a context it does not have.
+Admit a model only when `ollama show <m>` lists `tools` in Capabilities — the agent's job is run-command → read-output → decide.
+Reject reasoning models: the `<think>` block eats the output budget and can return empty content. Prefer `-instruct` variants.
+Keep the file ordered best → smallest; `lib/models.sh` takes the first row that fits `BUDGET_MB`.
+Keep rows tab-separated and hand-aligned — `models_rows` squeezes repeated tabs so a double tab cannot shift every field after it.
+Re-date the `# mini model registry — curated YYYY-MM` header comment in the same change.
+Never let a base model be launched directly: mini always runs the derived `mini-<base>:<n>k` variant with `num_ctx` baked in.
+The budget is VRAM minus 1GB on a GPU, 60% of RAM on CPU, capped at `qwen3:4b-instruct` on CPU.
+After a registry change run `bash .github/run-tests.sh` and then `bin/mini models` — the new row must show `fits` or `too big` against the real box.

+Keep ollama bound to `127.0.0.1:11434`; a public ollama has no authentication at all — `mini serve --local` is the only way back to loopback.
+Apply `OLLAMA_NUM_PARALLEL=1`, `OLLAMA_KEEP_ALIVE=30m`, `OLLAMA_FLASH_ATTENTION=1` and `OLLAMA_KV_CACHE_TYPE=q8_0` through `ollama_tune`, via a systemd drop-in or env vars when mini owns the process.
+`OLLAMA_NUM_PARALLEL=1` because opencode fires a title request next to the main one; two slots double the KV cache and thrash on CPU.
+Fail closed on a systemd rebind: if `daemon-reload` or `restart` fails, report it and leave the drop-in in place — never delete it to tidy up.
+`ollama_stop` returns 0 when the server was never started and removes only the pidfile mini owns, never a systemd unit.
+When ollama is systemd-managed, `mini stop` prints the `systemctl` command instead of killing the unit.
+Keep the request `timeout`/`chunkTimeout` in the provider options — the default kills a cold CPU request mid-prefill and the symptom is an empty response with nothing logged.
+After touching the lifecycle run `bash .github/run-tests.sh`; `tests/ollama_systemd_failure_test.sh` and `tests/ollama_bind_test.sh` are the contract.

+Write mini's config to `$MINI_HOME/opencode.json` and point `OPENCODE_CONFIG` at it; never read or write `~/.config/opencode/opencode.json`.
+Keep the generated file `0600` — it embeds the remote API key.
+Merge the user's existing opencode config into the generated one; when the old file cannot be parsed, preserve it byte-for-byte in a recovery backup and write the fresh default.
+The global tools mini installs live in `~/.config/opencode/tools/` and are namespaced `mini_*` so they cannot shadow an opencode built-in.
+A new tool needs all three parts: the bash script in `share/tools/`, the TS wrapper in `share/opencode-tools/`, a row in the tool table in `share/prompts/base.md` — plus a check in `lib/doctor.sh`.
+Slash commands are the `command` block in `opencode_write_config`; add them there, not in a separate file.
+Trim opencode's built-in tools to bash/read/write/edit and keep the prompt tight — every enabled tool ships its schema on every request.
+Keep the provider options carrying `baseURL`, `timeout` and `chunkTimeout`; the local provider is `ollama/<model>`, the remote one `mini-remote/<model>`.
+A `--model` override must resolve to its own run-scoped config and leave the live config byte-identical.
