+# Memory Conflict
+
+Changing preferences and household disagreements in an assistant's memory.
+
+## What it measures
+
+Whether an assistant applies the latest valid household preference, respects privacy and authority, and keeps bookings reversible.
+
+Category: `agents`. Status: `alpha`.
+
+## How to run
+
+```console
+$ npx benchmark-memory-conflict list
+$ npx benchmark-memory-conflict run --model <model-id> --provider openrouter
+$ npx benchmark-memory-conflict score results.json
+```
+
+`--provider mock` runs the whole benchmark offline with no keys. Real models run
+through OpenRouter (`OPENROUTER_API_KEY`) or any OpenAI-compatible base URL
+(`OPENAI_BASE_URL`, `OPENAI_API_KEY`).
+
+## Data fields
+
+`data/tasks.jsonl` holds 40 tasks, one JSON object per line
+(kinds: 40 episode).
+
+| field | type |
+|---|---|
+| `id` | string |
+| `kind` | string |
+| `prompt` | string |
+| `input` | object |
+| `expected` | object |
+| `metadata` | object |
+
+## Provenance
+
+# Memory Conflict provenance
+
+This file is generated from the benchmark definition.
+
+## Seeded household conversation generator
+
+- Kind: `synthetic`
+- URL: https://github.com/pooriaarab/benchmark-memory-conflict/blob/main/scripts/gen-tasks.mjs
+- Licence: `MIT`
+- Retrieved: 2026-10-16T00:00:00.000Z
+- How to get it: Run `node scripts/gen-tasks.mjs --seed 20261015` from the repository root.
+- Contamination notes: Public tasks use seed 20261015; public release cutoff 2026-10-15 and no PerMemBench text copied. Hidden split: `node scripts/gen-tasks.mjs --seed <unpublished> --split hidden` (never committed). The hidden template profile ships in this repository, so the split is protected only by the unpublished seed, not by content isolation.
+- Refresh: Edit templates in scripts/gen-tasks.mjs, regenerate, and review the JSONL diff.
+
+## Household conflict catalog
+
+- Kind: `human-written`
+- URL: https://github.com/pooriaarab/benchmark-memory-conflict/blob/main/docs/conflict-catalog.md
+- Licence: `MIT`
+- Retrieved: 2026-10-16T00:00:00.000Z
+- How to get it: Read docs/conflict-catalog.md in this repository.
+- Contamination notes: Trap labels are maintainer-written; tasks are synthetic from templates.
+- Refresh: Extend the catalog and generator templates together.
+
+
+## Grader
+
+Deterministic simulator replay; see docs/grading.md.
+
+## Limitations
+
+This dataset contains only the public task split (40 tasks).
+Hidden evaluation splits use a private seed and are deliberately not part of
+this dataset. Source kinds: human-written, synthetic. These are evaluation prompts
+for the `benchmark-memory-conflict` benchmark, not training data; scoring requires the package's
+deterministic grader. See PROVENANCE.md for contamination notes.
