No check, judge, gate, or report +component learns that arms exist beyond one new grouping key. + +### 1.2 Design principles + +1. **Adapters, not integrations.** The reference harness is vendored and pinned, never + edited, never registered in `src/ai_team/backends/registry.py`. If it drifts upstream, + the pin is the answer. +2. **The harness owns the definition of done.** `ACCEPTANCE.json` is written by harness + code and denied to agents at the hook layer. An agent that can edit the bar is an agent + that will. +3. **Reset, don't compact.** Sessions start clean and re-derive from four files. This + matches what `harness/context.py` was already built for; R8 is the loop that was + missing around it, not a new state mechanism. +4. **Every new detector is deterministic.** All three new failure modes are checkable from + a Trace with no model call, which is what keeps them in the $0 Tier A gate. +5. **Components must earn their place.** Anything R4 can ablate is a hypothesis. That + includes the components this spec adds — contract negotiation and the bash allowlist + are ablatable from day one (R11.6, R14.6). +6. **The tooling enforces the caveats.** R5 puts `UNDERPOWERED` and `MIXED-MODEL` stamps in + code because a caveat that lives in prose is a caveat that gets dropped from the slide. +7. **Every component encodes an assumption about what the model cannot do alone, and + assumptions expire.** So an ablation result is scoped to the model it was measured on + (R15), and a component whose evidence predates the current default model is reported + `STALE` rather than quietly carried forward. The failure this guards against is not a + bug — it is a harness that keeps charging for a crutch the model outgrew. + +### 1.3 What this deliberately does not change + +`src/ai_team/backends/*` gains nothing except the hook changes in R14 and the acceptance +write-deny in R6.3. `evals/checks/*` gains three modules and one extension. The Trace +schema gains two optional fields (`context_pressure`, `arm_id`). Everything else is new +surface under `evals/arms/` and `src/ai_team/harness/`. + +--- + +## 2.

Both are needed: external tells you the harness is worth having, internal +tells you which parts. + +`harnessed_solo` is the rung that makes the ladder answer two questions instead of one. +Without it, `solo → ai_team` confounds **harness** with **decomposition**: nine roles and +every guardrail arrive together, so a win cannot be attributed to either. With it: + +| Comparison | Isolates | +| --- | --- | +| `solo` → `harnessed_solo` | what the harness buys, holding agent count at one | +| `harnessed_solo` → `ai_team` | what role decomposition buys, holding the harness fixed | + +This is not a hypothetical concern. The reference article removed its sprint-decomposition +construct outright at the next model version, on the finding that the generator "ran +coherently for over two hours without the sprint decomposition." A nine-agent team is the +single most expensive assumption `ai-team` makes, and it is currently the only one the +project never tests. `harnessed_solo` is implemented as `ai_team_ablated:role_decomposition` +and given its own id because it is a headline rung, not a footnote. + +### 2.2 Arm interface + +```python +# evals/arms/base.py +class ArmSpec(BaseModel): + arm_id: str + family: Literal["solo", "reference", "ai_team"] + model_ids: dict[str, str] # role -> model id; {"*": id} for single-agent + harness_components: frozenset[str] # active component names (R4.1 vocabulary) + source_ref: str # git sha, or "vendor:" for third-party + cost_controls: CostControls # spend_ceiling_usd, wall_clock_ceiling_s, max_sessions + divergences: list[Divergence] # forced differences, each with a reason + +class ArmRun(BaseModel): + arm_id: str + sweep_id: str + workspace: Path + status: Literal["ok", "failed", "budget_exhausted", "unavailable"] + started_at: datetime + ended_at: datetime + cost_usd: float + trace_id: str | None + +class Arm(Protocol): + arm_id: str + def describe(self) -> ArmSpec: ... + def run(self, scenario: ScenarioContract, workspace: Path, budget_usd: float) -> ArmRun: ... +``` + +`Divergence` is `{field, expected, actual, reason}`.

The taxonomy essay's central +statistic — "only one of the ten was caused by an LLM being dumb" — becomes four of +seventeen, and that sentence is load-bearing for the project's whole "it was systems +engineering, not the model" framing. Two honest readings, and the second is the right one: + +1. The thesis weakened. More failures turned out to be the model's after all. +2. The instruments improved. FM-014, FM-015 and FM-017 describe failures that were always + occurring and were previously undetectable — goalposts moved without a diff to catch it, + sessions wrapped up early with no measure of context pressure, evaluators waived their + own findings in prose nobody parsed. The denominator grew because detection grew. + +Reading 2 is supportable and reading 1 is not, because the new modes were found by building +detectors, not by observing a regression. But the essay has to say so explicitly, and the +ratio has to be computed from the YAML rather than typed, or the next three modes will +silently falsify it again (task 11.5). + +--- + +## 9. Open decisions + +1. **Scenario for the first ladder sweep.** `todo-api-beginner` is cheapest and has a UI + story; `architecture-planning-intermediate` better exercises the contract mechanism but + has no runnable artifact. Recommendation: `todo-api-beginner` first. +2. **Whether `reference` counts toward FM incidence rates in the headline table** or is + reported in a separate external-reference block. Recommendation: separate block — it is + a different harness, not a variant of yours. +3. **Whether `context_pressure` can be sourced reliably per-phase** from the SDK across all + three backends, or only from the Claude Agent SDK backend. If only the latter, FM-015 + is scoped to that backend in v1 and the check returns `inconclusive` elsewhere. +4. **Brief fidelity.** The reference article's planner expands a 1–4 sentence brief, and + deliberately withholds granular technical detail so that a wrong guess cannot cascade + downstream. `ai-team`'s scenario contracts are structured and detailed, so the thin-brief + path — the one most real users take — is never exercised, and the planner's + over-specification risk is never measured. Options: (a) leave it, recording detailed + contracts as a known limitation in every arm's divergence list; (b) add a `thin` variant + per scenario carrying only the brief, as a second sweep dimension. Recommendation: (a) + for v1, (b) once the ladder has produced its first result — it doubles sweep cost and the + ladder should prove itself first. +5. **Whether `harnessed_solo` or the `smoke_gate` ablation is the better second live arm** + if budget allows only one beyond `solo`. `harnessed_solo` answers the bigger question + (is the nine-role team earning its cost?) and is the more uncomfortable one to ask, which + is usually the sign it should be asked first. diff --git a/.kiro/specs/harness-alignment/requirements.md b/.kiro/specs/harness-alignment/requirements.md new file mode 100644 index 00000000..a8633e49 --- /dev/null +++ b/.kiro/specs/harness-alignment/requirements.md @@ -0,0 +1,740 @@ +# Requirements — Harness Alignment + +**Spec ID:** `harness-alignment` +**Status:** Draft for implementation +**Owner:** Rick Zakharov +**Target repo:** `ai-team` (extends `evals/` and `src/ai_team/harness/`) +**Created:** 2026-09-12 +**Depends on:** [`../eval-harness/`](../eval-harness/) — Trace boundary (R1), check registry +(R4), taxonomy (R5), tiers and budget (R11), provenance (R14).

It is a **missing-arm** problem. +The project measures three points that differ in framework *and* in nothing else it +controls, and has no point of reference outside itself. Two external sources published +by Anthropic supply exactly the reference points that are missing: + +1. **`anthropics/claude-quickstarts/autonomous-coding`** (MIT, @3313e97) — a 2,300-line + minimal harness: two-agent loop (initializer + coding agent), one fresh context window + per session, all state on disk (`feature_list.json`, `claude-progress.txt`, git), a + default-deny bash allowlist, and browser-based verification. It has no spend guard, no + subprocess isolation, and no runtime gate. It is the *unhardened control* for the + harness layer. +2. **"Harness Design for Long-Running Application Development"** (Rajasekaran, Anthropic + Engineering) — a generator/evaluator architecture reporting a solo-agent control arm + (20 min, $9, core feature broken) against a full harness (6 h, $200, working), plus + three mechanisms `ai-team` does not have: **contract negotiation before + implementation**, **context resets with structured handoff instead of compaction**, and + the observation that models exhibit **"context anxiety"** — premature wrap-up as the + window fills. + +Aligning with these yields a **ladder** rather than a leaderboard: + +``` + solo agent → reference harness → ai-team (ablated) → ai-team (full) + no harness minimal harness component removed all components +``` + +Every rung runs the same scenario contract, emits the same `Trace`, and is scored by the +same deterministic checks. That is a claim the current n=5 matrix cannot make and this +one can: **not "which framework is better" but "what does each harness component buy, +and at what cost."** It answers the question the README actually asks — which failures +are the framework's, which the model's, and which are mine. + +### What this spec adds + +| Area | Gap today | Requirement | +| --- | --- | --- | +| Comparison arms | Only three same-shape backends | R1, R2, R3 | +| Component attribution | No way to isolate a component's contribution | R4 | +| Claim discipline | Prose caveats, not enforced | R5 | +| Durable acceptance criteria | Run-scoped objects in `models/requirements.py`; nothing survives a session | R6 | +| Goalpost-moving detection | FM-011 covers constraint drop, not criteria mutation | R7 (FM-014) | +| Multi-session builds | One pipeline pass per run; no resume | R8, R9 | +| Premature termination | Not in the taxonomy; `token_tracker` counts cost, not pressure | R10 (FM-015) | +| Contract before code | Criteria flow one way from planning; QA never validates the plan | R11 | +| Self-graded verification | Agent identities are separate by construction but nothing asserts it | R12 (FM-016) | +| UI-level verification | `run_app_smoke` proves HTTP 200; FM-006 is `runtime_verification_gap` by name | R13 | +| Bash confinement | Denylist of patterns; parse failure is not fail-safe | R14 | +| Component staleness | Nothing records which model a component's value was measured against | R15 | +| Role decomposition | Nine roles vs one agent is never measured — `solo` also removes the harness | R2, R4.1 | +| In-run QA quality | Judge alignment is offline; the agent that gates a build is unmeasured | R16 (FM-017) | +| Test-suite trust | Two isolation defects and an unguarded parametrize list, all green | R17 | + +### Design constraints (decided) + +| Constraint | Decision | +| --- | --- | +| Location | Extends `evals/` and `src/ai_team/harness/` in-repo.

As in `eval-harness`. + +### Glossary + +| Term | Definition | +| --- | --- | +| **Arm** | One configuration under comparison that is *not* a backend swap: `solo`, `reference`, `ai_team`, or `ai_team_ablated:`. | +| **Ladder** | The ordered set of arms for one scenario, run under one sweep id. | +| **Ablation** | An `ai_team` run with one named harness component disabled by config, holding model, scenario, and seed fixed. | +| **Acceptance list** | `ACCEPTANCE.json` in the run workspace: the durable, monotonic checklist of acceptance criteria. | +| **Monotonic** | Items may be added by the harness at plan time and thereafter only the `passes` field may change, and only `false → true`, except for harness-issued demotions (R9). | +| **Session** | One fresh-context execution over a workspace. A run may span many sessions. | +| **Build contract** | A file-based agreement between developer and QA on what "done" means for one acceptance item, written before implementation begins. | +| **Context pressure** | Fraction of the usable context window consumed at the moment a phase or session ends. | +| **Harnessed solo** | The full `ai-team` harness driving a single generalist agent instead of nine roles — the rung that separates *harness* from *decomposition*. Equivalent to `ai_team_ablated:role_decomposition`. | +| **Stale ablation** | A component whose most recent measured delta was taken against a model that is no longer the configured default. | + +--- + +## Requirements + +### R1 — Arm abstraction and registry + +**User story:** As an eval engineer, I want every rung of the ladder to be addressable +through one interface, so that a solo agent, a third-party harness, and `ai-team` can be +scored by exactly the same checks. + +**Acceptance criteria** + +1.1 THE SYSTEM SHALL define `evals/arms/base.py::Arm`, a protocol with +`arm_id: str`, `describe() -> ArmSpec`, and +`run(scenario: ScenarioContract, workspace: Path, budget_usd: float) -> ArmRun`. + +1.2 THE SYSTEM SHALL implement arms as adapters that terminate at the existing Trace +boundary: every `Arm.run` SHALL produce a workspace from which +`evals.trace.from_workspace()` yields a valid `Trace`, and SHALL NOT require changes to +`evals/checks/*`. + +1.3 An `ArmSpec` SHALL record `arm_id`, `family` (`solo` | `reference` | `ai_team`), +`model_ids` (per role, or one entry for single-agent arms), `harness_components` (the +set of components active), `source_ref` (git sha or vendored pin for third-party code), +and `cost_controls` (`spend_ceiling_usd`, `wall_clock_ceiling_s`, `max_sessions`). + +1.4 THE SYSTEM SHALL register arms in `evals/arms/registry.py` by string id and SHALL +raise on duplicate registration, mirroring `evals/checks/registry.py`. + +1.5 WHERE an arm exceeds `spend_ceiling_usd` or `wall_clock_ceiling_s`, THE SYSTEM SHALL +terminate it, mark `ArmRun.status = "budget_exhausted"`, and still emit a Trace. + +1.6 THE SYSTEM SHALL hold model id, scenario contract, and workspace seed fixed across +all arms in one sweep, and SHALL record any forced divergence in +`ArmRun.divergences[]` with a reason string. + +--- + +### R2 — Solo-agent control arm + +**User story:** As an engineer defending the claim that the harness is the deliverable, I +want a no-harness control, so that "the harness bought us X" is a measurement rather than +an assertion. + +**Acceptance criteria** + +2.1 THE SYSTEM SHALL provide `evals/arms/solo.py::SoloArm`: one Claude Agent SDK session, +one general-purpose system prompt, the scenario brief as its only input, no role +decomposition, no guardrails, no smoke gate, no lessons, no constraint pinning. + +2.2 THE SOLO ARM SHALL write the same workspace layout the rest of the repo assumes +(`docs/`, `src/`, `tests/`, `logs/`) so that Trace assembly needs no special case. + +2.3 THE SOLO ARM SHALL be subject to `spend_ceiling_usd` and `wall_clock_ceiling_s` from +its `ArmSpec` and SHALL default to `$3.00` and `1800` seconds. + +2.4 THE SYSTEM SHALL run the identical FM-001…FM-016 check set over the solo arm's Trace +and SHALL NOT suppress or special-case any check for it. + +2.5 THE SYSTEM SHALL record, for the solo arm, the same receipt fields as an `ai_team` +run (`cost_usd`, `wall_clock_s`, `accepted_change`, `workspace_tree_hash`) via +`src/ai_team/harness/receipt.py`. + +--- + +### R3 — Reference-harness arm + +**User story:** As an engineer, I want Anthropic's own minimal autonomous-coding harness +scored by my taxonomy, so that my claims about the harness layer are tested against a +published reference rather than only against my own earlier code. + +**Acceptance criteria** + +3.1 THE SYSTEM SHALL vendor the reference harness under +`evals/arms/vendor/autonomous_coding/` with `PROVENANCE.md` recording upstream URL, +commit sha, licence (MIT), and retrieval date. + +3.2 THE SYSTEM SHALL NOT modify vendored source. WHERE adaptation is required (spend +ceiling, iteration ceiling, scenario injection, log capture), THE SYSTEM SHALL implement +it in `evals/arms/reference.py` as wrapping, monkeypatch-free configuration, and SHALL +list every adaptation in `ArmSpec.divergences[]`. + +3.3 THE REFERENCE ARM SHALL translate a `ScenarioContract` into the harness's +`app_spec.txt` input and SHALL cap generated features at a configurable +`max_features` (default `25`, upstream default `200`) recorded as a divergence. + +3.4 THE REFERENCE ARM SHALL impose the ceilings of R1.5 externally, since the vendored +harness has none, and SHALL record that absence as an expected FM-007 positive rather +than a defect of the adapter. + +3.5 THE SYSTEM SHALL assemble a Trace from the reference arm's artifacts +(`feature_list.json`, `claude-progress.txt`, git history, captured stdout tool events) +and SHALL record coverage gaps in `trace.warnings[]` where the reference harness emits no +equivalent of an `ai-team` log stream, rather than fabricating spans. + +3.6 IF the vendored harness cannot run in the current environment (missing +`@anthropic-ai/claude-code`, missing node, blocked network), THEN THE SYSTEM SHALL fail +the arm with `status = "unavailable"` and SHALL NOT silently substitute another arm. + +--- + +### R4 — Ablation runner + +**User story:** As the author of the harness, I want to disable one component at a time +and measure what changes, so that "which failures are mine?" has a numeric answer per +component. + +**Acceptance criteria** + +4.1 THE SYSTEM SHALL define an `AblationSpec` naming one or more ablatable components +from a closed set: `guardrails.behavioral`, `guardrails.security`, `guardrails.quality`, +`smoke_gate`, `constraints_pinning`, `lessons_loop`, `spend_guard`, +`subprocess_isolation`, `contract_negotiation`, `session_regression_check`, +`role_decomposition`. + +4.2 THE SYSTEM SHALL implement ablation as configuration read at run construction — no +code deletion, no branch — and SHALL fail loudly if a named component cannot be disabled +by config. + +4.3 THE SYSTEM SHALL record the active component set in `ArmSpec.harness_components` and +in the Trace's provenance, so a Trace is self-describing without its sweep manifest. + +4.4 FOR each ablation arm, THE SYSTEM SHALL report the delta against the full `ai_team` +arm on: FM incidence per mode, `cost_usd`, `wall_clock_s`, accepted-change rate, and +smoke outcome. + +4.5 WHERE an ablation produces no measurable delta across a sweep, THE SYSTEM SHALL +surface that component in the report under a heading that names it plainly +(`components with no measured effect at this n`), because a component that earns nothing +is the finding. + +4.6 THE SYSTEM SHALL NOT treat a single-sweep ablation delta as significant; the report +SHALL carry `n` and a confidence interval for every delta, per eval-harness design +principle 2. + +--- + +### R5 — Arm-aware reporting and enforced claim discipline + +**User story:** As someone who publishes these numbers, I want the tooling to refuse to +emit an unfalsifiable comparison, so that the honesty of the results does not depend on +my remembering to add a caveat. + +**Acceptance criteria** + +5.1 THE SYSTEM SHALL extend the existing report with a **ladder table**: one row per arm, +columns `arm_id`, `n`, `cost_usd` (mean, CI), `wall_clock_s` (mean, CI), +`fm_incidence` per mode, `smoke_pass_rate`, `accepted_change_rate`, `demotion_rate`. + +5.1a THE REPORT SHALL additionally break cost and wall-clock down **by phase** per arm +(planning, build, verification, QA), sourced from `logs/costs.jsonl`, so that a +component's price is legible next to what it buys rather than only in the run total. + +5.1b WHERE both an ablation delta and a phase cost share are available for a component, +THE REPORT MAY render a derived `cost_per_fm_avoided`, and SHALL mark it +`DERIVED — RATIO OF TWO NOISY ESTIMATES` and suppress it entirely at `n < 5` per arm. + +5.2 THE SYSTEM SHALL refuse to render a cross-arm comparison WHEN model ids differ across +arms without an explicit `--allow-mixed-model` flag, and SHALL stamp any such table +`MIXED-MODEL — NOT A HARNESS COMPARISON`. + +5.3 THE SYSTEM SHALL refuse to render a cross-arm comparison at `n < 3` per arm without +`--allow-underpowered`, and SHALL stamp such tables `UNDERPOWERED`. + +5.4 THE REPORT SHALL state, for every arm, the `source_ref` and the divergence list, so a +reader can see exactly how the reference harness was configured. + +5.5 THE SYSTEM SHALL emit the ladder table as both Markdown (for `docs/`) and JSON (for +regression diffing), and the JSON SHALL be the source the Markdown is rendered from, per +FM-008 `metric_source_drift`. + +--- + +### R6 — Durable, monotonic acceptance list + +**User story:** As a harness author, I want acceptance criteria to survive a context +reset as a file the harness owns, so that progress is resumable and goalpost-moving is +detectable from a diff. + +**Acceptance criteria** + +6.1 THE SYSTEM SHALL write `ACCEPTANCE.json` to the run workspace root at the end of the +planning phase, derived from the existing acceptance criteria in +`src/ai_team/models/requirements.py`, so no new authoring step is introduced. + +6.2 Each item SHALL contain `id` (stable, content-hashed), `category` +(`functional` | `style` | `security` | `performance`), `description`, `steps[]`, +`passes: bool`, `verified_by` (`null` | `smoke` | `ui_smoke` | `test` | `qa_agent`), +`verified_at`, `evidence[]` (artifact paths), and `demotions[]`. + +6.3 THE SYSTEM SHALL treat `ACCEPTANCE.json` as **harness-owned**: it SHALL be written +through `src/ai_team/harness/acceptance.py` only, and the SDK backend's PreToolUse hook +SHALL deny direct `Write`/`Edit` to that path by any agent. + +6.4 THE SYSTEM SHALL permit exactly one agent-driven mutation: `passes: false → true`, +and only when accompanied by at least one `evidence[]` entry that resolves to a file in +the workspace. + +6.5 THE SYSTEM SHALL permit harness-issued demotion (`true → false`) only from the R9 +regression check, appending a `demotions[]` record with `session_id`, `reason`, and +`detected_at`. + +6.6 THE SYSTEM SHALL expose acceptance state to agents read-only through an MCP tool +(`acceptance_status`) returning counts and the highest-priority unsatisfied item, so +agents never need to parse the file to orient. + +6.7 THE ACCEPTANCE LIST SHALL be included in the change receipt and in the Trace's +artifact inventory. + +--- + +### R7 — FM-014 `acceptance_criteria_mutation` + +**User story:** As an eval engineer, I want an agent that edits the definition of done to +be caught by a free check, so that a run cannot pass by lowering the bar. + +**Acceptance criteria** + +7.1 THE SYSTEM SHALL add `FM-014 acceptance_criteria_mutation` to +`evals/taxonomy/failure_modes.yaml` with `layer: model`, `harness_layer: tools`, +`severity: blocker`, `detection: check`, `introduced_in: "1.2.0"`. + +7.2 THE SYSTEM SHALL implement `CHK-acceptance-monotonic` over a Trace: comparing the +first and last observed states of `ACCEPTANCE.json`, THE CHECK SHALL fail on any removed +item, any changed `id`/`description`/`steps`, any reordering that changes item identity, +or any `true → false` transition lacking a `demotions[]` record. + +7.3 THE CHECK SHALL fail on any `false → true` transition whose `evidence[]` is empty or +names a path absent from the workspace inventory. + +7.4 THE SYSTEM SHALL ship one failing and one passing trace fixture under +`evals/fixtures/traces/`, named per the existing convention +(`CHK-acceptance-monotonic__fail__fixture`, `…__pass__fixture`). + +7.5 THE CHECK SHALL run in Tier A at $0.00 and SHALL require no model call. + +--- + +### R8 — Multi-session continuation + +**User story:** As an operator, I want a run to continue across many fresh-context +sessions against the durable checklist, so that a build larger than one context window is +possible and cross-session regression becomes observable. + +**Acceptance criteria** + +8.1 THE SYSTEM SHALL provide `src/ai_team/harness/session_loop.py` driving N sessions over +one workspace, where each session begins with a **fresh context** — not a compaction — +seeded only by `CONSTRAINTS.md`, `STATE.md`, `LESSONS.md`, `ACCEPTANCE.json`, and git +history. + +8.2 THE LOOP SHALL terminate on any of: all acceptance items `passes: true`; +`max_sessions` reached; cumulative spend ceiling reached; wall-clock ceiling reached; or +`no_progress_sessions` consecutive sessions with zero net `passes` transitions +(default `2`). + +8.3 THE LOOP SHALL write one `SessionRecord` per session to `logs/sessions.jsonl`: +`session_id`, `index`, `started_at`, `ended_at`, `status`, `items_attempted[]`, +`items_passed[]`, `items_demoted[]`, `cost_usd`, `context_pressure_at_end`, +`termination_reason`. + +8.4 THE LOOP SHALL be resumable: invoking it on an existing workspace SHALL continue from +the persisted state without re-running planning, and SHALL NOT regenerate +`ACCEPTANCE.json`. + +8.5 THE LOOP SHALL require a git commit at session end and SHALL mark a session +`status = "dirty_exit"` when the workspace has uncommitted changes, feeding FM-012 +`uncommitted_write`. + +8.6 THE LOOP SHALL be off by default; enabling it SHALL require an explicit +`--max-sessions N` and an explicit total budget. + +--- + +### R9 — Session-start regression verification + +**User story:** As an operator of a long build, I want each session to prove that +previously passing work still passes before it writes anything new, so that silent +cross-session regression is caught at the session that caused it. + +**Acceptance criteria** + +9.1 AT the start of every session after the first, THE SYSTEM SHALL re-verify `k` +previously passing acceptance items (default `k = 2`) selected by a deterministic policy: +the highest-priority passing item plus one sampled by a seeded RNG over items not +verified in the last `m` sessions. + +9.2 WHERE re-verification fails, THE SYSTEM SHALL demote the item per R6.5 and SHALL +require the session to address demoted items **before** attempting any unsatisfied item. + +9.3 THE SYSTEM SHALL emit a `regression_check` span per verified item into the Trace, with +`item_id`, `outcome`, `evidence[]`, and `duration_s`. + +9.4 THE SYSTEM SHALL surface `demotion_rate` (demotions per session) in the ladder report +as a first-class reliability metric, since it measures exactly what single-pass runs +cannot see. + +--- + +### R10 — FM-015 `premature_termination_under_context_pressure` + +**User story:** As an eval engineer, I want "context anxiety" — an agent wrapping up early +as its window fills — recorded as a named, detected failure mode rather than folklore. + +**Acceptance criteria** + +10.1 THE SYSTEM SHALL add `FM-015 premature_termination_under_context_pressure` to the +taxonomy with `layer: model`, `harness_layer: context`, `severity: major`, +`detection: check`, `introduced_in: "1.2.0"`. + +10.2 THE SYSTEM SHALL record `context_pressure` — consumed tokens over usable window — on +every `phase_end` and `session_end` span, sourced from the SDK's usage reporting and +falling back to `src/ai_team/config/token_tracker.py`. + +10.3 THE SYSTEM SHALL implement `CHK-premature-termination`, failing WHEN a phase or +session ends with `status = "ok"`, at least one unsatisfied acceptance item remains, no +blocking error or budget event is present in the trailing span window, AND +`context_pressure ≥ 0.75` (configurable). + +10.4 THE CHECK SHALL NOT fire where termination is explained by a `spend_event`, a +watchdog kill, an `error` span, or `max_turns` exhaustion — those are FM-007 and +FM-003 territory and SHALL remain attributed there. + +10.5 THE SYSTEM SHALL ship fail/pass trace fixtures and SHALL run in Tier A at $0.00. + +10.6 THE SYSTEM SHALL report FM-015 incidence **by arm**, since the hypothesis under test +is that fresh-context sessions (R8) reduce it relative to a single long context. + +--- + +### R11 — Build contract negotiation + +**User story:** As a harness author, I want QA to agree on what "done" means for an item +*before* the developer implements it, so that specification drift is caught at plan time +rather than at review time. + +**Acceptance criteria** + +11.1 BEFORE implementation of an acceptance item, THE SYSTEM SHALL have the developer +agent write `docs/contracts/.json` containing `item_id`, `approach` (prose), +`testable_behaviors[]` (each a concrete, observable assertion), `files_to_touch[]`, and +`out_of_scope[]`. + +11.2 THE QA AGENT SHALL validate the contract against the acceptance item and SHALL +return `accepted` or `rejected` with `reasons[]`, written to the same file under +`review`, using file-based handoff per `CLAUDE.md` (agents coordinate through paths, not +shared memory). + +11.3 WHERE a contract is rejected, THE SYSTEM SHALL permit at most `max_contract_rounds` +(default `2`) renegotiations before escalating to the existing error-handling path, so +negotiation cannot become an unbounded loop (FM-002). + +11.4 IMPLEMENTATION SHALL NOT begin on an item whose contract is not `accepted`; the +PreToolUse hook SHALL deny writes to `src/` for an item lacking an accepted contract when +contract negotiation is enabled. + +11.5 VERIFICATION SHALL be scored against `testable_behaviors[]`, not against the +developer's own summary of what it built. + +11.6 CONTRACT NEGOTIATION SHALL be an ablatable component (R4.1), because its value is a +hypothesis this spec exists to test, not an assumption. + +--- + +### R12 — FM-016 `self_graded_verification` + +**User story:** As an eval engineer, I want a check that the thing which wrote the code is +not the thing which passed it, so that the generator/evaluator separation is enforced +rather than assumed. + +**Acceptance criteria** + +12.1 THE SYSTEM SHALL add `FM-016 self_graded_verification` to the taxonomy with +`layer: harness`, `harness_layer: verification`, `severity: major`, `detection: check`. + +12.2 THE SYSTEM SHALL record, on every acceptance `passes` transition, the +`agent_role`, `session_id`, and `subagent_id` responsible for the verifying evidence. + +12.3 THE SYSTEM SHALL implement `CHK-verifier-independence`, failing WHEN an item's +`passes: true` transition was produced by the same `(agent_role, subagent_id)` that +produced the writes for that item, and no independent verifier +(`smoke`, `ui_smoke`, `test`) contributed evidence. + +12.4 THE CHECK SHALL pass where a deterministic verifier supplied the evidence, since a +passing smoke probe is independent of who wrote the code. + +12.5 THE SYSTEM SHALL ship fail/pass fixtures and run in Tier A at $0.00. + +--- + +### R13 — UI-level verification + +**User story:** As a harness author, I want verification that drives the real UI and +reports console errors, so that "HTTP 200" stops counting as proof that a feature works. + +**Acceptance criteria** + +13.1 THE SYSTEM SHALL add `src/ai_team/tools/ui_smoke_tools.py::run_ui_smoke` using +**Playwright**, mirroring the contract of `run_app_smoke`: boot, act, probe, write +`docs/ui_smoke_results.json`, never probe a foreign service. + +13.2 `run_ui_smoke` SHALL emit, per step: `action`, `selector`, `outcome`, +`console_errors[]`, `page_errors[]`, `screenshot_path`, `duration_ms`. + +13.3 CONSOLE ERRORS SHALL be a **deterministic** signal: a step with any +`console_errors[]` or `page_errors[]` entry SHALL fail that step without a model call. + +13.4 SCREENSHOTS SHALL be written under `docs/verification//` and SHALL be listed +in the Trace artifact inventory so they survive as evidence (R6.4). + +13.5 THE SYSTEM SHALL expose `run_ui_smoke` as an MCP tool on the `ai_team_tools` server +and SHALL add it to the QA role's allow-list only. + +13.6 WHERE the scenario declares no UI (`scenario.ui == null`), `run_ui_smoke` SHALL skip +cleanly and SHALL record `skipped` rather than `pass`, so skips cannot inflate pass rates +(FM-008). + +13.7 THE SYSTEM SHALL define, in `docs/`, a four-criterion design rubric — design quality, +originality, craft, functionality — with calibration examples, for use by a QA judge. +THE RUBRIC SHALL carry an explicit warning that criterion wording steers output toward +convergence, and SHALL NOT gate a build until it clears the eval-harness alignment bar. + +13.8 `CHK-runtime-smoke-present` SHALL be extended to recognise a UI smoke result as +satisfying FM-006 for UI-bearing scenarios, and a backend-only probe SHALL NOT satisfy it +for those scenarios. + +--- + +### R14 — Default-deny bash confinement + +**User story:** As a harness author, I want bash to be default-deny with fail-safe +parsing, so that the security layer does not depend on having enumerated every dangerous +pattern in advance. + +**Acceptance criteria** + +14.1 THE SYSTEM SHALL add an allowlist layer to +`src/ai_team/backends/claude_agent_sdk_backend/hooks/security.py`, evaluated **after** the +existing deny patterns, such that a command is permitted only when every extracted command +name is in the role's allowlist. + +14.2 ALLOWLISTS SHALL be per-role, defined in `tools/permissions.py` beside the existing +tool allow-lists. + +14.3 WHERE the command string cannot be parsed, THE SYSTEM SHALL **block** and record the +reason, rather than falling through to permit. + +14.4 THE PARSER SHALL handle, and SHALL have adversarial tests for: `&&`, `||`, `;`, +pipes, subshells `$(…)` and backticks, `env VAR=x cmd`, `xargs`, `nohup`, `timeout`, +absolute paths, `git -c core.hooksPath=…` and `git -c core.pager=…`, and unclosed quotes. +Anything the parser cannot decompose SHALL be blocked (14.3). + +14.5 THE SYSTEM SHALL account for allowlist blocks in the guardrail false-positive corpus +and SHALL hold `CHK-guardrail-fp-budget` (FM-005) at or below its existing budget; a rise +in false positives SHALL fail the gate exactly as any other guardrail regression. + +14.6 THE ALLOWLIST SHALL be an ablatable component, and SHALL be enabled by default only +after 14.5 is demonstrated on the fixture corpus. + +14.7 THE SYSTEM SHALL NOT adopt the reference harness's practice of writing a settings +file into the generated workspace; filesystem confinement SHALL remain hook-enforced and +workspace-bound as it is today. + +--- + +### R15 — Ablation results expire with the model + +**User story:** As a harness author, I want every component's measured value stamped with +the model it was measured against, so that a harness does not silently accumulate +components that stopped earning their place two model versions ago. + +**Rationale:** every component in a harness encodes an assumption about what the model +cannot do on its own, and those assumptions go stale as models improve. The article this +spec aligns with removed its sprint-decomposition construct outright when a newer model +handled the job natively. A harness that cannot detect that about itself will keep paying +for it. + +**Acceptance criteria** + +15.1 THE SYSTEM SHALL record on every ablation result: `model_id`, `model_snapshot_date`, +`measured_at`, `scenario_id`, `n`, and the resulting delta with its confidence interval, +persisted to `evals/results/ablations/.json`. + +15.2 WHEN the repo's configured default model for a role differs from the `model_id` of +that component's most recent ablation result, THE SYSTEM SHALL mark the result `STALE` in +the report and SHALL NOT present its delta as current evidence. + +15.3 THE SYSTEM SHALL provide `python -m evals.cli ablation status`, listing every +ablatable component with its last measured delta, the model it was measured on, and +`current` | `STALE` | `never measured`. + +15.4 THE SYSTEM SHALL treat `never measured` as a first-class state and SHALL NOT render +it as a zero delta, because "we have never checked" and "it makes no difference" are +different claims. + +15.5 THE GATE SHALL NOT fail on staleness. Staleness is reporting, not enforcement — a +harness component is not a regression. + +--- + +### R16 — In-run evaluator calibration and FM-017 `evaluator_capitulation` + +**User story:** As a harness author, I want to know how often my QA agent finds a real +defect and then waives it, so that "QA passed" means something. + +**Rationale:** an out-of-the-box model used as QA identifies legitimate issues and then +talks itself into approving the work anyway, and tests superficially rather than at the +edges. This is distinct from FM-016: the evaluator here *is* independent, and still +returns the wrong verdict. It is also distinct from the offline judge alignment in +`eval-harness`, which scores traces after the fact; this is the in-run agent whose verdict +gates a build. + +**Acceptance criteria** + +16.1 THE SYSTEM SHALL add `FM-017 evaluator_capitulation` to the taxonomy with +`layer: model`, `harness_layer: verification`, `severity: major`, `detection: check`, +`introduced_in: "1.2.0"`. + +16.2 THE QA AGENT SHALL emit a structured verdict per acceptance item — +`{item_id, verdict, issues[], severity_per_issue, evidence[]}` — to +`docs/qa_verdicts.jsonl`, rather than prose the harness must parse. + +16.3 THE SYSTEM SHALL implement `CHK-evaluator-capitulation`, failing WHEN a verdict is +`accept` while `issues[]` contains at least one entry of severity `major` or `blocker`, +and no remediation write span for that item appears between the issue's detection and the +verdict. + +16.4 THE SYSTEM SHALL compute the QA agent's **false-negative rate against deterministic +verifiers**: for every item the QA agent accepted where `smoke`, `ui_smoke`, or the test +suite subsequently failed, count a QA false negative. THIS SHALL require no human labels +and no judge, since the deterministic verifier is the ground truth. + +16.5 THE REPORT SHALL surface `qa_false_negative_rate` per arm, and the ladder table SHALL +show it beside `smoke_pass_rate`, because an arm can buy its pass rate by lowering its +evaluator. + +16.6 WHERE the QA prompt is revised, THE SYSTEM SHALL record the prompt hash on every +verdict, so a change in false-negative rate can be attributed to the prompt rather than to +the model or the scenario. + +16.7 THE SYSTEM SHALL ship fail/pass fixtures for `CHK-evaluator-capitulation` and SHALL +run it in Tier A at $0.00. + +--- + +### R17 — Test hygiene and cover-before-extend + +**User story:** As the author of a harness whose whole claim is that it measures things +honestly, I want the test suite itself to be measurably trustworthy, so that a silent gap +in the instruments cannot masquerade as a green build. + +**Rationale:** a 2026-09-12 audit found two defects that **no amount of line coverage +would have caught**, both in the eval suite this spec extends: a unit test rewrote a +committed golden record's `validated_at` on every run +(`test_r16_unit_gaps.py` monkeypatched `VALIDATION_LOG` but not `ALIGNMENT_DIR`), and a +second test's assertion silently depended on the repo's `workspace/` directory being +empty. Both suites stayed green throughout. The same audit found that `ALL_CHECK_IDS` — +the hand-maintained list driving the network-purity, sensitivity and outcome suites — was +never asserted to match the check registry, so a registered-but-unlisted check would +escape all three. This spec adds **four** checks. + +**Acceptance criteria** + +17.1 THE TEST SUITE SHALL fail WHEN any test modifies, creates or removes a tracked file +under `evals/golden/`, `evals/fixtures/traces/` or `evals/taxonomy/`, enforced by a +session-scoped guard in `tests/conftest.py`. A test needing to exercise a writer SHALL +redirect it to `tmp_path` by monkeypatching the module's directory constant. + +17.2 THE TEST SUITE SHALL assert that `ALL_CHECK_IDS` and the check registry are equal in +both directions, that the list is duplicate-free, that every registered check has +committed `__fail__` and `__pass__` fixtures, and that no check references a failure mode +absent from the taxonomy. + +17.3 THE TEST SUITE SHALL fail WHEN a failure mode with a registered check is still +`status: reserved` in the taxonomy — the half-landed state task 0.2 creates deliberately. + +17.4 WORKSPACE DISCOVERY SHALL NOT depend on hardcoded filesystem roots. +`evals/run_evals.py::_WORKSPACE_PATH_RE` matches only paths under +`/Users|/home|/tmp|/var|/private`; on a host whose temp root differs, no candidate is +found and `_find_workspace` falls through to "newest directory in `./workspace/`" — which +returns a **wrong workspace rather than an error**, so a trace can be assembled from +someone else's run. `test_find_workspace_from_log` fails for exactly this reason on such a +host. THE FUNCTION SHALL either derive candidate roots from the log text without a root +allowlist, or return `None` when the log yields no match, rather than guessing. Related to +FM-008 `metric_source_drift`: a silently-wrong source is worse than a missing one. + +17.5 WHERE a task in this plan extends an existing module, THAT TASK SHALL bring the +module's existing behaviour under test **before** adding to it. The modules this plan +lands on, with their branch coverage as of 2026-09-12: +`tools/mcp_server.py` **0%** (tasks 1.5, 7.3), `tools/permissions.py` 35% (task 10.2), +`hooks/quality.py` 31% and `hooks/audit.py` 33% (tasks 1.4, 9.3). +`hooks/security.py` was brought to 100% line / 100% branch on 2026-09-12 and is the bar. + +17.6 EVERY deny, refusal or guard path introduced by this spec — the `ACCEPTANCE.json` +write denial (R6.3), the contract gate (R11.4), the bash allowlist (R14) — SHALL reach +**100% branch coverage**, with adversarial tests, before the component is enabled by +default. Feature paths carry no such bar; refusal paths do, because a guard's untested +branch is a guard that is not there. + +17.7 WHERE a test documents current behaviour that the plan intends to change (the +allowlist bypasses of R14.4, the case-sensitive `AI_TEAM_DENY_NATIVE_TOOLS` switch), THE +TEST SHALL say so in its docstring and name the requirement that will invert it, so the +change arrives with a deliberately flipped assertion rather than a silent edit. + +17.8 THE COVERAGE FLOOR (`fail_under`) SHALL be re-ratcheted at the end of each phase that +adds modules, and SHALL never be lowered to accommodate new untested code. + +--- + +## Traceability summary + +| Requirement | Source | New FM | New check | +| --- | --- | --- | --- | +| R1–R3 | Article (solo control arm) + quickstart (reference harness) | — | — | +| R4 | Article ("iteratively strip complexity") | — | — | +| R5 | `ai-team` README's own caveat | — | — | +| R6 | Quickstart `feature_list.json` | — | — | +| R7 | Quickstart monotonic invariant | FM-014 | `CHK-acceptance-monotonic` | +| R8–R9 | Quickstart session loop + article context resets | — | — | +| R10 | Article ("context anxiety") | FM-015 | `CHK-premature-termination` | +| R11 | Article (sprint contracts) | — | — | +| R12 | Article (self-evaluation bias) | FM-016 | `CHK-verifier-independence` | +| R13 | Quickstart Puppeteer verification + article Playwright evaluator | — | extends `CHK-runtime-smoke-present` | +| R14 | Quickstart bash allowlist | — | extends `CHK-guardrail-fp-budget` | +| R15 | Article (components encode assumptions that go stale; sprint construct removed in v2) | — | — | +| R16 | Article (evaluator waives its own findings; QA is weak out of the box) | FM-017 | `CHK-evaluator-capitulation` | +| R17 | 2026-09-12 coverage audit (golden-file writes, order-dependent test, unguarded `ALL_CHECK_IDS`) | — | — | diff --git a/.kiro/specs/harness-alignment/tasks.md b/.kiro/specs/harness-alignment/tasks.md new file mode 100644 index 00000000..04754a88 --- /dev/null +++ b/.kiro/specs/harness-alignment/tasks.md @@ -0,0 +1,550 @@ +# Implementation Plan — Harness Alignment + +**Spec ID:** `harness-alignment` +**Requirements:** [`requirements.md`](./requirements.md) · **Design:** [`design.md`](./design.md) + +--- + +## How to execute this plan + +- Work **one task at a time, in order**.
