Every command so far asked an addition question — what to add, what to move, what it costs. Nothing asked what is no longer earning its always-loaded rent. This adds that axis as a fourth lensCheck on the existing hybrid motor rather than a new scanner or a 22nd command: the measured payoff (~18% of one file) justifies a mode, not machinery. It is the only lens that proposes REMOVING config, so it carries a guarantee the others don't need: a load-bearing block is never a candidate. Precision is asymmetric — a missed dead line costs a few tokens per turn, a deleted one costs a wrong remote or a broken script — so the floor is decided in code (lib/floor-exclusion.mjs) before the opus judge sees anything, never in prose. Granularity is the leaf block, with two structural exceptions: a paragraph ending in ':' merges with the list it introduces, and an ordered list is a contract whose steps inherit floor from any sibling. Unordered lists deliberately do not inherit — a load-bearing bullet and a disposable one routinely share a list, and container-reasoning is the error the hand-built ground truth exists to catch. Verified against that ground truth (built before any classifier existed), with the comparison machine-checked rather than read by eye: zero load-bearing blocks proposed, 11/18 deletable groups surfaced, ~756 tok ~ 18% of a ~4300 token file — inside the pre-registered band. The first run found five floor violations the synthesized fixture missed; each got a structural rule and a fixture shape so it cannot regress. Three real bugs the dogfood run exposed, all now covered: - JS \b is ASCII-only, so /\bunngå\b/ never matches — every Norwegian keyword ending in æ/ø/å was silently dead. - A bare word/word is not a path; "pros/cons" vetoed the largest deletable block until PATH_RE was tightened to rooted paths and globs. - "Mid-sentence" must key on a preceding lowercase letter; the loose version read **bold labels:** and quoted openers as entities, costing 4 of 11 groups. BP-SUB-001 is grounded entirely in the Anthropic steering blog already cited by BP-MECH-001..004 and asserts nothing from the talk that motivated the feature — no "80%", no ablation figure. Suite 1365 -> 1382/0. Frozen v5.0.0 snapshots untouched; plain optimize output byte-identical on identical input (--subtract adds keys only when passed). knowledge-refresh-cli's reference date moved to 2026-08-01: its premise that every seed entry was verified 2026-06-20 expired when BP-SUB-001 got a genuine verification date, and backdating the entry to fit the test would have been a lie about when its source was checked.

# Subtraction shapes — synthesized fixture
|
|
|
|
This fixture reproduces the *discriminating shapes* from the hand-built subtraction fasit
|
|
(økt #40) without reproducing any of the operator's private config text. Every block below
|
|
exists to make one classification call hard in the same way a real block was hard.
|
|
|
|
Both languages appear on purpose: the config this lens was designed against is Norwegian
|
|
prose with English identifiers, and a detector that only speaks English would score well
|
|
here and fail in the field.
|
|
|
|
## Preferences
|
|
|
|
- Language: Norwegian for dialogue, English for code and documentation.
|
|
- Tone: direct and technical, minimal ceremony.
|
|
- Format: be concrete and action-oriented, avoid unnecessary text.
|
|
- Never say "as an AI I cannot"; skip apologies and over-explanation.
|
|
|
|
## Kodepreferanser
|
|
|
|
- TypeScript > JavaScript
|
|
- Readability > cleverness
|
|
- Conventional Commits: `type(scope): description`
|
|
|
|
## Oppstart
|
|
|
|
1. Run `pwd` to see where you are.
|
|
2. Read the nearest STATE.md and confirm the active task.
|
|
3. Sjekk `git status` mot det STATE.md hevder.
|
|
4. Summarize before you do anything.
|
|
|
|
## Arbeidsregler
|
|
|
|
- Commit often with descriptive messages.
|
|
- Test incrementally, and ask when blocked.
|
|
- Tenk før du koder — uttal antakelser eksplisitt og spør ved tvetydighet.
|
|
- Aldri gjett på rotårsak; undersøk først.
|
|
|
|
## Defensive shell-scripting
|
|
|
|
- Alltid siter variabel-ekspansjoner (`"$var"`) — en usitert ekspansjon brøt en zsh-loop.
|
|
- Hold testkode ASCII-ren; et multibyte-tegn krasjet bash 3.2 under `set -u`.
|
|
|
|
## Anti-patterns
|
|
|
|
- Do not one-shot large features.
|
|
- Never declare "done" without running the tests.
|
|
- Aldri jobb i et annet repo enn det økten står i. Hvert repo eier sin egen
|
|
versjonsplan og sin egen tilstand. Skriver du der, tar du beslutninger på
|
|
deres vegne uten deres kontekst — `coord-send` er mekanismen, send arbeidet
|
|
dit i stedet.
|
|
- Do not refactor as part of a bugfix without approval.
|
|
|
|
## Git
|
|
|
|
- Aldri GitHub. Kun Forgejo (`git.example-forge.test`). Aldri `gh` CLI.
|
|
- Etter `git commit`: push til Forgejo umiddelbart.
|
|
|
|
## Miljø
|
|
|
|
- System bash er **3.2**: ingen `declare -A`, ingen `readarray`.
|
|
- Alle hook-scripts må være 3.2-kompatible.
|
|
|
|
## Modellvalg
|
|
|
|
Default for alt arbeid er Opus 4.8 med xhigh effort. Ingen annen modell skal brukes.
|
|
Sett `model: "opus"` på hver spawn. Haiku: aldri.
|
|
|
|
## Secrets
|
|
|
|
- ALDRI commit secrets. Bruk `.env`/`.template`-mønsteret.
|
|
|
|
### The Iron Law: NO PRODUCTION CODE WITHOUT A FAILING TEST FIRST
|
|
|
|
## Arbeidsflyt
|
|
|
|
Default for alle oppgaver: forstå problemet, vurder alternativer, presenter dem,
|
|
og vent på bekreftelse før du implementerer. Ved usikkerhet om en oppgave faller
|
|
i unntakene: den gjør det ikke.
|
|
|
|
**Viktig:** `/harness continue` og andre skills styrer sin egen workflow.
|
|
|
|
## Kodeblokk
|
|
|
|
```bash
|
|
# Never run this in production, and always check every time first.
|
|
echo "avoid unnecessary output"
|
|
```
|
|
|
|
## Kontinuitet
|
|
|
|
Konteksten mellom sesjoner hviler på tre lag med hver sin ene jobb:
|
|
- **`STATE.md`** — current state-of-play der du jobber. Overskrives alltid ved sesjonsslutt.
|
|
- **`MEMORY.md`** — varige fakta om bruker. Hold den under 200 linjer.
|
|
|
|
## Verktøy
|
|
|
|
- Deleger arbeid til subagenter, og bruk Explore for søk.
|
|
- Skriv alltid kortest mulig kode.
