Only fail assertions whose own selectors don't match. + +**File:** `packages/imhotep-playwright/src/public.ts` (extraction batching logic) + +--- + +### 2. Dense DSL Size Assertions Broken at Runtime + +**Bug:** `ui.spec("'.button' atLeast 44px wide")` parses correctly but `checkAll()` throws `IMH_EXTRACT_PROTOCOL_ERROR: Unsupported selector format: `. The empty reference string `''` is included in `allSelectors`, and `materializeSemanticSelector` rejects it. + +**Impact:** All unary size assertions via dense DSL are broken. Fluent API works fine. + +**Fix:** In `lowerSizeAssertionToCanonical`, either omit `reference` field for unary assertions, or make extraction pipeline skip empty selectors. + +**File:** `packages/imhotep-dsl/src/compiler.ts` (empty reference handling) + +--- + +### 3. Default Gap Bounds Are Infinite (Relations Always Pass) + +**Bug:** `leftOf` / `rightOf` / `above` / `below` default `minGap` to `-Infinity` and `maxGap` to `Infinity`. This makes `ui.expect('.a').to.be.leftOf('.b')` pass even when `.a` is to the right of `.b`. + +**Impact:** Relations without explicit gap bounds assert nothing. Users think they're testing position when they're not. + +**Fix:** Default `minGap` to `0` for directional relations. Require explicit negative gap if overlap is intended. + +**File:** `packages/imhotep-solver/src/predicates.ts:296-297` + +--- + +### 4. `space: 'layout'` Option Ignored in Options Object + +**Bug:** `{ space: 'layout' }` passed in relation options is silently ignored. Only `.layout.to.be.leftOf(...)` chaining works. + +**Impact:** Users following README examples with `{ space: 'layout' }` get visual-space evaluation instead. + +**Fix:** Copy `space` from `RelationOptions` to AST in `FluentRelation.toAst()`. + +**File:** `packages/imhotep-dsl/src/fluent.ts:636-638` + +--- + +### 5. `focus-visible` Kebab-Case Rejected + +**Bug:** `ui.materializeState('.button', 'focus-visible')` throws "not supported". Internal validator only accepts `'focusVisible'` (camelCase). + +**Impact:** Users following common CSS convention get errors. + +**Fix:** Normalize kebab-case to camelCase before validation, or accept both forms. + +**File:** `packages/imhotep-playwright/src/page.ts:151` + +--- + +### 6. Property Runner Creates Fresh Page Per Case + +**Bug:** `createFixtureRendererAdapter` and `createComponentRendererAdapter` create a new page and navigate on EVERY mount. No caching state exists despite documentation claiming "page state caching reduces per-case overhead from ~770ms to ~60-90ms." + +**Impact:** Property runs are ~10x slower than documented. CI timeout risk. + +**Fix:** Implement `cachedFixtureId`, `cachedImhotepPage`, and `containerReady` state as described in NEXT_STEPS_429.md. + +**File:** `packages/imhotep-playwright/src/public.ts:2033-2119` + +--- + +## P1 — API / Documentation Mismatches (Mostly Fixed in V1.1) + +Historical findings from the V1.1 audit. Items marked **FIXED** are resolved. + +### 1. `imhotep/property-contracts` Subpath Doesn't Exist + +**Issue:** README shows `import { generatedDomain } from 'imhotep/property-contracts'` but the `imhotep` package has no `./property-contracts` export. + +**Fix:** Change all docs to `import { generatedDomain } from 'imhotep'` or add the subpath export. + +--- + +### 2. Property Runner Requires `ImhotepRuntime`, Not `Page` + +**Issue:** README shows passing `page` directly to `forAllProps(page, domain, runner)`, but the implementation requires `ImhotepRuntime` (created via `createRuntime(browser)`). + +**Fix:** Either update docs to show `createRuntime()` usage, or make property runners accept `Page` and wrap it internally. + +--- + +### 3. `scene.expect(selector).atLeast(config)` Doesn't Work + +**Issue:** Property runner callbacks show `scene.expect(selector).atLeast({ width: 50 })` but the actual API is `scene.expect(selector).to.be.atLeast(50, 'width')`. + +**Fix:** Update all examples in README, SKILLS.md, and property runner docs. + +--- + +### 4. Property Run Order Is Concurrent, Not Sequential + +**Issue:** `exhaustivelyForAllInputs` runs cases in parallel. Documentation implies sequential enumeration. + +**Fix:** Document concurrent execution, or add `concurrency: 1` option for sequential runs. + +--- + +### 5. Dense DSL `between` Size Assertions Not Supported + +**Status: FIXED in V1.1** — Dense DSL now supports `between` size assertions. + +--- + +### 6. Dense DSL Quantifier Syntax Is Inline, Not Block + +**Status: FIXED in V1.1** — Both inline (`all '.item' above '.footer'`) and block (`forall $btn in buttons('.primary'): ...`) syntax work. + +--- + +## P2 — Surprising Behaviors (Documented for V1.1, Some Fixed in V1.1) + +### 1. `.inside()` Checks ALL Matching Reference Elements + +**Behavior:** When multiple elements match the reference selector, `.inside()` checks against all of them. The subject must be inside ALL matching references. + +**Impact:** `ui.expect('.button').to.be.inside('.container')` fails if there are 2 `.container` divs and the button is only inside one. + +**Fix Options:** +- Document this behavior clearly +- Add `insideAny()` for "inside at least one" semantics +- Default `.inside()` to "inside at least one matching reference" + +--- + +### 2. Cardinality Assertions Evaluated Outside FOL Engine + +**Behavior:** `exactlyOne()`, `atLeastN()`, `atMostN()` bypass the FOL solver and use direct `selectorToIds` count checks. + +**Impact:** Contradicts "all assertions compile to FOL" claims in architecture docs. + +**Fix Options:** +- Register cardinality as FOL predicates (`count(elements('.x')) >= N`) +- Or update docs to acknowledge cardinality is pre-FOL + +--- + +### 3. `checkAll()` Auto-Clears Assertion Store + +**Behavior:** After `checkAll()`, the internal assertion arrays are emptied. This is correct but not explicitly documented. + +**Impact:** Users might expect to call `checkAll()` multiple times on the same assertions. + +**Fix:** Document the auto-clear behavior in README and SKILLS.md. + +--- + +### 4. Presets Expose Internal Clause Descriptors + +**Behavior:** Presets return `{ assertions: [...], clauses: [...] }` where `clauses` is internal `CanonicalClauseDescriptor[]`. + +**Impact:** Users can inspect what a preset will test before running, but this leaks internal structure. + +**Fix:** Document the `clauses` field or hide it behind a symbol. + +--- + +### 5. Invalid Options Silently Accepted + +**Behavior:** `ui.expect('.a').to.be.leftOf('.b', { invalidOption: true })` is silently forwarded to the FOL engine without validation. + +**Impact:** Typos in option names are silently ignored instead of reported. + +**Fix:** Add strict option validation in `FluentRelation.toAst()` or DSL validator. + +--- + +### 6. `separatedFrom` Fails With Generic Error + +**Status: FIXED in V1.1** — `separatedFrom` is now fully implemented as a spatial relation. + +--- + +## P3 — Missing Features (Documented But Don't Exist) + +| Feature | Documented In | Status | Action | +|---------|---------------|--------|--------| +| `clippedBy` fluent assertion | Architecture docs | NOT IMPLEMENTED | Remove from docs or implement | +| `geom` lower-level primitives | imhotep-specification.md | NOT EXPORTED | Remove from proposed API or implement | +| `.and` chaining on relations | README, spec | IMPLEMENTED in V1.1 | Available in both fluent and dense DSL | +| `in(frame.viewport())` syntax | imhotep-playwright-cdp-impl.md | NOT IMPLEMENTED | Remove or implement | +| Temporal assertions (`during`, `at`) | imhotep-specification.md | NOT IMPLEMENTED | Mark as V1.2+ | +| Perceptual tolerance engine | Architecture docs | NOT IMPLEMENTED | Mark as V1.2+ | +| `imhotep-temporal` package | imhotep-llm-execution-strategy.md | DOESN'T EXIST | Remove from package list | +| `imhotep-perception` package | imhotep-llm-execution-strategy.md | DOESN'T EXIST | Remove from package list | +| Property runner page caching | NEXT_STEPS_429.md, docs | IMPLEMENTED in V1.1 | Caching reduces per-case overhead from ~770ms to ~60-90ms | +| `imhotep-cli` dist directory | package.json bin field | MISSING | Build dist or fix bin path | + +--- + +## V1.1 Definition + +### What V1.1 Means + +V1.1 is the **"Works As Documented"** release.
