continuous-integration/drone/push Build is passing
feat(lvl5): P1 — 5-rung ladder (L5=abra recipe lint) + de-capped level semantics
level.py: RUNGS += lint; statuses {pass,fail,skip,unver}; compute_level = max passed
rung with all below pass-or-skip (fail/unver block); cap_reason/capped DELETED.
harness/lint.py: lint executor — pristine scratch clone of the per-run tree at the
exact tested ref (mirror-origin + untracked-overlay pollution solved by context, no
rule filtered), PTY via script -qec, 60s hard budget, lint.txt artifact, table-parse
classifier (rc only signals FATA), unver on any non-run (never silent pass).
results.py: derive_rungs classifies every N/A source (structural/declared → skip,
else unver), lint rung + synthetic lint stage + lint block in results.json, schema 2,
cap fields removed. run_recipe_ci.py: lint call before tiers (double-wrapped,
verdict-neutral), badge = level only. card/dashboard: 0-5 ramp, cap line → 'level N
of {4|5}', unverified rows, badge number+colour only, lint.txt servable, old schema-1
artifacts render untouched. Unit suite rewritten: 245 passed on cc-ci venv.

"""Structured run results + results.json (Phase 3 §4.2 R1/R3; level semantics: phase lvl5).
Turns a run's per-tier pytest outcomes into a single `results.json` artifact carrying:
{ recipe, version, pr, ref, run_id, finished, stages:[{name,status,tests:[{name,status,ms}]}],
level, rungs, lint:{status,detail,rules_failed},
skips:{intentional:{rung:reason}, unintentional:[rung]},
flags:{clean_teardown,no_secret_leak}, screenshot, summary_card }
Rung statuses (phase lvl5, operator-decided — see harness.level + DECISIONS.md): every rung is
"pass" | "fail" | "skip" (INTENTIONAL — a declared/structural fact says the rung does not apply)
| "unver" (UNINTENTIONAL — the rung should have run and wasn't verified; blocks the level like a
fail). `derive_rungs` is the single place every N/A source is classified; anything it cannot
attribute to a declared/structural fact defaults to "unver" (conservative). `skips` mirrors that
split into results.json: intentional {rung: reason} / unintentional [rung] (= the unver rungs).
The per-test breakdown comes from JUnit XML emitted by each tier's pytest invocation (`--junitxml`),
parsed here with the stdlib (no new dep). The integer **level** is computed by harness.level from a
rung-status dict derived here (`derive_rungs`) from the tier results + structural signals the
orchestrator holds; the classification table is in DECISIONS.md (phase lvl5).
This module is import-pure (no side effects at import). `write_results` is the only writer; the
orchestrator calls the build/write path inside a try/except so a results failure NEVER changes the
run's exit code (R7 — cosmetics never block the pipeline).
