What & why

Closes #473.

Loop runtime rules currently allow matching by task ID, domain/type, or complexity independently. This adds a deterministic conjunctive selector for domain/type + complexity, so delivery workflows can choose a runtime for a lane like backend/low without creating task-specific rules.

The resolution contract is:

  • specificity: id > type + complexity > type > complexity
  • matching rules merge non-empty runtime fields
  • later rules win per field when specificity is equal
  • legacy ID-only, type-only, and complexity-only rules keep their behavior

This is a generic Loop capability: it introduces no consumer-specific enum or dependency.

This change was co-written with Codex. I reviewed the diff and verification results before opening the PR.

How you verified it

  • make gate — PASS
    • 24,733 Go tests passed; 3 platform-specific tests skipped
    • codegen, formatting, Go/TS lint, typecheck, web tests/build, Go build, and package boundaries passed
  • Focused runtime/config/native-tool suite — 504 tests passed
  • Config, API, native-tool, runtime selection, status, and event round-trip coverage included
  • Local integration exercised distinct backend/low and frontend/medium matrix routes through real Loop execution

Impact

  • config.toml runtime rules may combine match.type and match.complexity
  • runtime selection preserves the conjunction through config, API, native tools, status, and runtime_applied observability
  • public configuration and Loop skill documentation are updated
  • no database migrations, dependency changes, scheduler changes, or concurrency changes

  • make gate passes locally
  • New and changed behavior is covered by tests that failed before the implementation and pass afterward
  • Agent-assisted changes are disclosed above and were reviewed and verified

Summary by CodeRabbit

  • New Features
    • Added flexible runtime-rule matching by task ID, type, complexity, or type-and-complexity combinations.
    • Runtime settings can now be combined across matching rules, with more specific matches taking precedence.
  • Bug Fixes
    • Improved validation and handling of runtime rules, including legacy-compatible JSON behavior.
  • Documentation
    • Clarified supported matchers, precedence, and rule-merging behavior.
  • Tests
    • Added coverage for matching, validation, schema enforcement, configuration propagation, and runtime selection.

Walkthrough

Runtime rules now support conjunctive type and complexity selectors. Resolution applies deterministic specificity, field-level merging, and later-rule overrides. Strict schemas, validation, configuration round trips, dry runs, and fan-out execution tests cover the behavior.

Combined selectors require both task fields. Resolution ranks id, combined, type-only, and complexity-only matches. Matching rules merge runtime fields and apply later equal-specificity values.
Configuration and tool propagation
internal/config/loops_test.go, internal/daemon/native_loop_tools_test.go
Workspace cloning and native loop dry runs preserve multiple runtime rules. Invalid matchers, runtime objects, and unknown fields are rejected before loop service invocation.
Runtime selection integration

Fan-out execution verifies complexity, type, combined, and exact-ID selection, including resolved runtime fields, speed resolution, and provenance.

Verdict

The approach is right and fits the repo's premises. Requesting changes only for the two items below — the design itself is approved.

Why the design is sound

The main thing I checked was whether this bakes consumer-specific behavior into the core. It doesn't:

  • type and complexity were already first-class match fields before this PR (resolver, CLI flag, contract, item extraction). The PR only extends the match grammar over existing fields — no new domain concept enters the core.
  • No fixed vocabulary: both fields stay free-form strings (minLength: 1). Compozy doesn't know what "backend" or "high" mean; task authors own the vocabulary. The issue's non-goal ("no global domain enum") is honored.
  • Policy stays in config, mechanism stays in core: rules are operator/agent-authored data; the core only implements deterministic matching + per-field merge with provenance.
  • The per-item escape hatches remain above rules in precedence: the typed type: runtime input and task frontmatter runtime still override config rules (runtime_resolve.go). The layering is unchanged; the policy layer just got more expressive.
  • The path-envelope guard in ItemRuntimeFromNamespace still prevents arbitrary fan-out objects from opting into rule matching.

Also verified: single-selector rules keep identical behavior (relative specificity order preserved), the native-tool schema tightening (additionalProperties: false) only surfaces earlier the errors deep validation already rejected, digests/testdata updated, and the surfaces are closed end-to-end (config.toml, definition, HTTP/UDS, native tools, site docs, official skill).

Requested changes (blocking)

  1. Remove .superpowers/sdd/2026-08-24-compozy-conjunctive-runtime-rules/task-1-report.md. This is a contributor-tool artifact and introduces a new top-level directory that isn't a repo convention. Task artifacts belong under .compozy/tasks/<slug>/; QA evidence under docs/qa/. The docs/qa/ report and scenario updates in this PR are correct and should stay.

  2. File a follow-up issue for the loop: transition conflict: Goal session cleanup ... payload changed daemon error recorded in the QA evidence, and reference it from docs/qa/reports/2026-08-24-conjunctive-runtime-rules.md. The blocked-verify status is acceptable per the QA contract (the integration test covers per-item resolution), but the live-run failure that blocked settlement smells like a pre-existing Goal-session cleanup bug and needs its own tracked issue so the scenario can be re-walked after merge.

Non-blocking notes

  • Matcher grammar (medium-term flag): the matcher is now a closed 3-field grammar with a hardcoded specificity ladder. This one conjunction touched 21 files; every future dimension (area, risk, language…) would repeat that cost. If a third dimension ever lands, the right move is a hard cut to free-form label matching (match.labels.<key>, specificity = number of matched labels, id stays exclusive) rather than a fourth special field. Nothing to change now — with two combinable dimensions the closed grammar is the simpler, more auditable choice, and this PR doesn't make that future cut harder.
  • The compact --runtime CLI syntax staying single-selector is fine, since per-run conjunctions are reachable via --config <file> and the limitation is documented in the skill reference.

@pedronauck Addressed both blocking items in 87522fba0:

The runtime-selection scenario remains blocked-verify; #480 now tracks the blocker so it can be re-walked independently of #473.
