 # Changelog
 
+## 0.6.2 - 2026-09-22
+
+- Retain the PSL normalization fact in compact catalogs and exercise the review
+  queue against the compact runtime rather than only the full writer projection.
+
+## 0.6.1 - 2026-09-22
+
+- Accept complete Common Crawl domain-rank releases containing provider rows
+  that are not valid DNS hostnames. Such rows remain authenticated and counted
+  in source coordinates but cannot match or enter the official-domain catalog.
+- Keep malformed graph schemas and numeric fields fail-closed, with a regression
+  derived from the real `com.your_domain` provider row.
+
+## 0.6.0 - 2026-09-22
+
+- Add a streaming Common Crawl domain Web Graph adapter for harmonic-centrality,
+  PageRank, and member-host evidence while preserving exact provider fields and
+  source-line coordinates.
+- Authenticate and validate the complete rank stream but retain only registrable
+  domains already asserted by imported public identity sources, avoiding a
+  multi-gigabyte runtime catalog whose unrelated rows cannot resolve routes.
+- Bind every compact graph projection to the SHA-256 of its sorted candidate
+  domains and fail closed when identity evidence, the PSL, the bound scope, or a
+  selected graph row is absent.
+- Teach scheduled updates to import identity sources before automatically binding,
+  downloading, and importing Web Graph evidence with `{candidate_domains}`.
+- Strictly allowlist official HTTPS domain-rank objects and retain Common Crawl
+  Terms-of-Use attribution without treating authority as ownership, safety,
+  reviewer approval, or query popularity.
+- Update Rustls to 0.23.45, remediating RUSTSEC-2026-0285 in the dataset
+  acquisition path.
+
 ## 0.5.0 - 2026-09-13
 
 - Add a streaming ROR 2.1 ZIP adapter with exact schema checks, declared domains,

+### Common Crawl Web Graph
+
+The adapter accepts the official domain-level rank object whose exact header is:
+
+```text
+#harmonicc_pos\t#harmonicc_val\t#pr_pos\t#pr_val\t#host_rev\t#n_hosts
+```
+
+It reverses `host_rev` (`com.facebook` to `facebook.com`) and retains harmonic
+centrality, PageRank and `n_hosts` as source-separated popularity evidence.
+`n_hosts` means hosts belonging to the registered domain and is exposed as
+`member_hosts`; it is not an inbound-link count. The adapter creates no entity,
+name, official-site edge, review, vote or route.
+
+Only exact domain-rank objects below the official
+`data.commoncrawl.org/projects/hyperlinkgraph/<release>/domain/` hierarchy are
+allowlisted. Use `compression: gzip`, the exact release ID as the snapshot, a
+positive byte ceiling, and typed coverage. The downloader and importer hash and
+consume the complete object; a byte-range prefix must not be declared as the
+complete source. Common Crawl's Terms of Use are not an SPDX open-data license,
+so preserve the Terms link and re-review it on each acquisition.
+
+Domain-rank files contain tens of millions of rows. Import the PSL and public
+identity sources first, then run `web-graph-selection --database ...` to obtain
+the exact `candidate-domains:<sha256>` scope. A scheduled update may instead use
+the `{candidate_domains}` token. The importer still parses and authenticates the
+complete stream but persists only matching registrable domains, with original
+row coordinates. This keeps the public updater reproducible and compact. Rank
+still cannot replace reviewer quorum or destination-safety checks.

+
+## Scope and trust
+
+The v0.6.2 catalog contains 976 entities, 1,062 official-site edges, 20,178
+multilingual name facts, and Common Crawl Web Graph evidence for 840 domains that
+already had imported identity assertions. Graph authority can prioritize review
+and disambiguation, but cannot create an identity, official-site assertion,
+review, vote, or redirect. The archive includes all 33 authenticated cold audit
+objects referenced by the compact runtime generation.
+
+The bounded Wikidata discovery input is broad but not a representative or
+high-demand sample. Its query and selection metadata are included for audit; raw
+discovery output is never approval.
+
+The disclosed policy uses one automated evidence-gate reviewer group rather than
+claiming human-review quorum. Fresh exact endpoint observations are required, and
+source conflicts or dangerous drift need two groups, so the single automated
+reviewer must abstain on those risks. Sticky revocations and
+publisher/reviewer-key separation remain enabled.
+
+Consumers decide whether this policy is appropriate for their use. Preserve typed
+abstentions, retain attribution, and apply independent malware and content policy.
+Do not route to the first raw lookup result. High-risk or disputed catalogs should
+use the unchanged two-human-reviewer reference policy.
+
+The generation's approvals expire. Installing an immutable archive is not a promise
+that every decision stays valid forever: use the resolver's requested time,
+consume cumulative signed revocation feeds when published, and move to a newly
+signed full generation before relying on renewed decisions.
+
+## Regular updates
+
+The public source repository includes the same updater used to refresh candidate
+generations. The example systemd timer runs weekly. It can download, authenticate,
+import and build, but it holds no publisher key and cannot approve, sign or
+activate a candidate. That separation lets any consumer automate evidence updates
+without allowing a compromised downloader or changed upstream dataset to silently
+change redirects.

+
+Patch release 0.6.1 additionally replays the real provider-shaped
+`com.your_domain` case: the row remains in authenticated input/coordinate
+accounting but is not retained as a DNS target. The following valid
+`com.facebook` row is retained at its original `row:2` coordinate. Schema and
+numeric corruption continue to fail closed.
+The compact-generation lifecycle now also executes the review queue, proving its
+PSL normalization input remains in the runtime catalog.
+
+The evaluation contract was written before implementation. The new Common Crawl
+domain-rank integration passed five default integration tests; its sixth test is
+an explicit resource benchmark. The benchmark parsed 100,000 valid provider-shaped
+rows, retained exactly one identity-matched domain, and completed in 0.52 seconds
+of test time. The enclosing warm Cargo process used 79,944 KiB peak RSS, wrote
+9,136 filesystem blocks, and used no swap on the development machine. These are
+engineering bounds, not a full 2 GiB provider-object throughput claim.
+
+`scripts/check.sh` passed after the v0.6 version and Rustls lockfile updates. It
+covered formatting, offline all-target checks, strict Clippy, all Rust and CLI
+tests, documentation, Python release-package tests, and native/Python consumer
+parity. The focused graph suite proves full-stream schema/value validation,
+source-line provenance, gzip authentication, exact URL allowlisting, deterministic
+builds, compact candidate-domain selection, and zero route authorization from
+rank evidence.
+
+The networked `cargo audit --deny warnings` gate initially detected
+RUSTSEC-2026-0285 in Rustls 0.23.43. The lockfile was updated to Rustls 0.23.45;

+
+The policy keeps sticky revocations, requires separate reviewer and publisher
+keys, blocks source conflicts and dangerous drift, and gives those risk classes
+a two-group threshold that this automated identity cannot satisfy. Ambiguous,
+conflicting, stale, unobserved, expired, or revoked routes therefore abstain.
+
+Consumers choose whether to trust this publisher and policy. The stricter
