+The CLI `--input` option currently accepts local file paths. It does not fetch URLs such as `http://` or `https://`.
+
+URL-bearing metadata inside JSON, XML, HTML, or `DocumentInput.source` is preserved as source/reference metadata for evidence and rendering. To summarize remote content, fetch it outside this tool and pass the saved local file or normalized payload.

 For high-quality summaries of new documents, connect an LLM summarizer at the cache-miss step. Keep the output structured as `DocumentSummaryState`.
 
+OpenAI-backed runs can be configured with explicit model, timeout, retry, and token-budget controls:
+
+```bash
+OPENAI_API_KEY="..." python -m document_briefing_cache.cli run \
+  --input examples/mixed_documents.json \
+  --summary-mode openai \
+  --openai-model gpt-4.1-mini \
+  --llm-timeout 60 \
+  --llm-max-retries 2 \
+  --llm-max-input-tokens 12000 \
+  --llm-max-output-tokens 4000 \
+  --cache-dir .cache \
+  --show-stats
+```
+
+When a document exceeds the input budget, the OpenAI adapter summarizes section-based chunks and merges the structured states before writing the document summary cache. Oversized sections are split into smaller text parts while preserving the original section ID for evidence validation. Transient provider failures, including rate limits, server errors, timeouts, and connection-style failures, are retried with exponential backoff; structured-output contract failures are not retried.
+
 Privacy note: `rules` mode is local and token-free. LLM-backed summarizers send cache misses to the configured provider, such as OpenAI, and require the relevant API key. Cache directories are plaintext JSON and may persist structured summaries, names, IDs, dates, metrics, evidence quotes, sources, and rendered outputs. HMAC detects tampering but does not hide contents. Keep `.cache/` out of git, use encrypted storage or tmpfs when needed, and use `ephemeral`, `--redact-pii`, or explicit cache clearing for sensitive documents.
 
+Evidence note: `DocumentSummaryState` schema `1.1.0` requires evidence for the top-level summary and each section digest, in addition to evidence for key points, decisions, actions, risks, and metrics. Evidence quotes should be copied from the normalized source sections so validation can reject unsupported claims and stale `1.0.0` document-summary caches.

+- HMAC signing is tamper detection only, not encryption. Use encrypted storage, tmpfs, or another encrypted backend when cache contents need confidentiality.
 - Do not use this skill to review or debug source code. It may summarize code-review notes or PR discussion documents when they are supplied as document-like inputs.
 - If an input type is unfamiliar, normalize it to text plus metadata and mark uncertainties in `unknowns`.

 Environment:
 
 - Python 3.14.4
-- Installed with `python3 -m pip install --user --break-system-packages -e ".[dev]"`
+- Source-tree validation used the local Python environment with pytest available.
 - Pytest capture used `TMPDIR=/tmp` so temp files are created on a POSIX filesystem.
+- Local `python3 -m build` was unavailable in this environment (`No module named build`).
 
 Commands:
 
 ```bash
 TMPDIR=/tmp PYTEST_DISABLE_PLUGIN_AUTOLOAD=1 PYTHONDONTWRITEBYTECODE=1 PYTHONPATH=src python3 -m pytest -q
-PYTHONDONTWRITEBYTECODE=1 PYTHONPATH=src python3 scripts/validate_skill.py

+TMPDIR=/tmp PYTEST_DISABLE_PLUGIN_AUTOLOAD=1 PYTHONDONTWRITEBYTECODE=1 PYTHONPATH=src python3 -m pytest tests/test_distribution_smoke.py -q
+```
+
+`tests/test_distribution_smoke.py` is opt-in and skips unless `DBC_RUN_INSTALLED_SMOKE=1` is set. The default local command above confirms the skipped source-tree test is present; it does not by itself install or smoke-test built artifacts.
+
+CI performs wheel and sdist artifact install smoke validation by building distributions, installing each artifact into a fresh virtual environment, and running the renderer from `/tmp` so default templates must be loaded from packaged resources rather than repository-local files.
+
+Local artifact smoke requires the `build` module plus explicit virtual environment install commands. Example:
+
+```bash
+python3 -m build
+python3 -m venv /tmp/dbc-wheel-venv
+/tmp/dbc-wheel-venv/bin/python -m pip install dist/*.whl
+/tmp/dbc-wheel-venv/bin/python -m pip install pytest
+(cd /tmp && DBC_RUN_INSTALLED_SMOKE=1 /tmp/dbc-wheel-venv/bin/python -m pytest /path/to/repo/tests/test_distribution_smoke.py -q)
