# 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,
website links, names, aliases, external identifiers, status, type, country and
administrative metadata while preserving ROR identities independently.
- Advance source manifests to v3 with source-bound content/provider checksums,
explicit direct and upstream lineage, authenticated per-record limits and exact
provenance for every imported or derived fact.
- Stream multiline Wikidata JSON arrays and typed JSON deltas, including auditable
tombstones when official-website statements disappear.
- Add compact runtime generations backed by content-addressed cold audit bundles,
complete verification and export, signed no-deletion retention checkpoints and
exact active-source binding in generation receipts.
- Add lineage-aware evaluation reports and a reproducible, resource-bounded
benchmark harness with exact input, output, process and hardware evidence.
- Harden ZIP expansion limits, audit reads, foreign-key restoration, disk-full
import recovery and output-exhausted benchmark process cleanup.
## 0.4.0 - 2026-09-13
- Add typed full/partition/delta source coverage, active-record masking, a

The parser streams the documented top-level JSON array without assuming that an
entity is physically one line, and handles concatenated compressed streams. It
rejects a record above the authenticated 16 MiB default; after inspecting the
exact object, a publisher can bind a larger limit with `--maximum-record-bytes`
on `download` or `manifest`, up to the 256 MiB audit-safe ceiling. Do not use
truthy RDF: it loses statement evidence. Full
dumps need substantial disk space and a long sequential scan even though memory
is bounded. A small entity selection is useful on limited hardware.
Wikidata's current Add/Change artifacts are XML history/stub streams. Wikidata's
own download guidance warns that JSON embedded in XML dumps is unstable, so this
release refuses that format. For bounded incremental refresh, acquire official
Wikibase API `wbgetentities` JSON, declare typed `delta` coverage against the
exact selected-entity base and apply consecutive sequences. A changed entity with
no P856 statements emits an empty record, which becomes a website-evidence
tombstone in the audit export. Reconcile API deltas against a later full JSON dump
before replacing broad production coverage.

### 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.

## Data boundaries
`sources`, `records`, and `facts` preserve provider-native evidence. Typed
The writer's `sources`, `records`, and `facts` preserve provider-native evidence. Typed
coverage selects a coherent active set without deleting older snapshots.
`selected_sources` and `active_records` record that derivation. Names, entities,
web properties, edges, popularity, and rejected facts are deterministic
projections.
A compact build packages every completed source into a content-addressed cold
JSONL bundle before removing superseded records and unprojected fact history from
the runtime copy. `COMPLETE.json` binds every bundle and the runtime database.
Normal queries need only the compact generation. Audit export, verification and
retention checkpoints stream the external bundle store and fail on absence,
substitution, truncation, malformed order, or mismatched source/attribution.
Names, website edges, and entity equivalences have separate material
fingerprints. Adding an alias therefore cannot inherit an approved destination,
and changing unrelated entity metadata does not invalidate an unchanged website

# Benchmarking and recovery
`scripts/benchmark.py` runs one import, build, audit verification, or evaluation
command without a shell and creates a new evidence directory. `REPORT.json`
records exact source-manifest and source-object hashes, hardware, wall/CPU time,
peak RSS, database/record/fact growth, hashes of stdout/stderr, optional measured
artifacts, and a hash of the argument vector. Source bytes are never copied into
the report. The command refuses to overwrite an existing directory.
Use three profiles consistently:
- `small`: synthetic or source-shaped fixtures used for correctness and rapid
regression checks;
- `medium`: a documented provider subset large enough to exercise checkpoints,
bounds and projection behavior; and
- `provider`: one complete current official provider object in its native format.
Example import measurement:
```bash
python3 scripts/benchmark.py --profile provider \
--output /data/benchmarks/ror-v2.12-import \
--source-manifest /data/cache/ror/source.json \
--database /data/ror-writer.sqlite --expanded-bytes 362619018 -- \
argand-site-registry import --database /data/ror-writer.sqlite \
--input /data/cache/ror/SHA256 --manifest /data/cache/ror/source.json
```
For build measurements, label exact regular files with repeated
`--measured-path NAME=PATH`. Run evaluation with at least 1,000 representative
cases in one process so authenticated startup/copy time remains separate from
the report's native per-query p50/p95. Store reports outside Git because commands
and snapshots can reveal private operational structure. A report establishes one
machine and object only; synthetic numbers are never provider-capacity evidence.
## Version 0.5 provider canary
The 2026-09-13 canary used official ROR release `v2.12-2026-08-25`, Zenodo record
`22099990`. The compressed object was 36,246,232 bytes, SHA-256
`5779c7baf71771fd8ea829201e7bd4343a3c68ff36c595f480b3a00292f78931`, and
matched provider MD5 `ce8807691455d4ada3216c31408e9e1a`. Its JSON and CSV
members expanded to 362,619,018 bytes.
The final streaming import produced 137,398 records and 914,439 facts in 62.30
seconds (9.47 user, 13.24 system), with 25,032 KiB peak RSS and about 14,678
facts/second. It grew the PSL-initialized writer by 828,682,240 bytes to
829,505,536 bytes. Reimport replayed the complete pinned source in 0.025 seconds
without changing any record, fact, or database byte count.
A compact build combining that ROR source with the current PSL projected 137,398
entities, 131,591 properties and 133,398 edges. The pre-compaction database was
1,345,097,728 bytes; the runtime database was 824,705,024 bytes, a 38.688%
reduction. The initial compact build took 58.36 seconds with 45,140 KiB peak RSS;
a second build reused the same bundles and produced byte-identical database and
receipt bytes. The two cold bundles totaled 686,468,048 bytes and held 137,399
records plus 914,440 facts. Warm-cache full streaming audit verification took
3.03 seconds with 24,076 KiB peak RSS.
A 1,000-case safe-abstention evaluation passed 1,000/1,000 with native reusable
reader latency of 72 microseconds p50 and 96 microseconds p95. The warm-cache full
process took 0.83 seconds, including authentication and the private copy of the
786.5 MiB SQLite file. Serving deployments must reuse the verified `Registry` and
must measure cold startup on their own storage.
Hardware: Linux 6.18.51-1-lts x86_64, AMD Ryzen 9 7900X (12 cores, 24 logical
CPUs), 61 GiB RAM, ext4. These numbers are a single local canary and not a public
service capacity claim.
## Recovery matrix
The acceptance suite sends real process termination after two distinct committed
checkpoints and proves the same import completes exactly once on restart. The
provider canary also killed the final binary at a 2,304-record checkpoint via a
bounded-runner fault, recovered its hot journal, and reached the exact clean-import
record/fact totals. Other tests cover handled parser failure rollback, SQLite growth-cap
(`SQLITE_FULL`) behavior, truncated/compressed inputs, mutated cache objects,
duplicate records and JSON keys, archive-member drift, missing/truncated/substituted
cold bundles, existing publication targets, failed atomic writes, and unchanged
previous generations after update failure. Provider objects and benchmark output
remain outside the repository.

## Argand integration
`UPSTREAM.json` records the original Argand extraction baseline and file hashes.
The last recorded downstream integration replaced Argand's embedded crate with
signed v0.3.0 revision `ac8282093d8a815c6227cff86e1f40714d510bcd` at Argand
commit `d9dfd1585ce21d9c4136bcc24fa01fe3bfb8ed6e`.
Argand's prior integration pinned signed v0.5.0 revision
`3d3e08cdfd303df9fbd347a9bab2ba52ad575759`. Argand now pins the public signed
v0.6.2 source release at `3c89a540d910cb298ba752880efeb1ed157dab43` in
downstream commit `224616eb9f6685d1a656b113b8460fb80c0c5a6b`.
The public beta uses Site Registry as Navigate's authoritative auto-route
catalog. Its native `navigation-catalog/v2`
file is only a collection- and content-policy-bound serving projection compiled
from one exact registry generation; it is not a second independently curated
destination catalog.
Version 0.4 is handed off as a signed standalone revision. Argand should update its
full Git `rev` in a separate coordinated source/build window, compare contract
changes, and rerun navigation compiler, native resolver, API, abstention,
revocation and clean-process gates. Changing the code dependency does not activate
a registry generation or approve a public destination.
Argand source commit `564ee5fc2fa0974a7b0557a914f274bbd4ab654c` records that boundary and the first
public-beta activation. Changing the code dependency alone still does not activate
a data generation or approve a destination. Every downstream must verify the
signed generation, preserve abstentions, apply its own safety policy, and bind any
serving projection to its own eligible corpus or directory policy.

Version 0.6 uses writer schema 5 and `argand.site-rules/v4`. Schema identifiers

The Common Crawl domain-rank adapter is new in 0.6, so no older v4 store can
contain one of its source manifests. Its replacement scope is
`candidate-domains:<sha256>`, where the digest covers the canonical JSON encoding
of the sorted set of registrable domains derived from retained complete website
assertions. Retained superseded evidence may enlarge this conservative set but
cannot create a route or make a retired assertion active.
The importer authenticates and validates every graph row but persists only the
selected domains. A changed identity frontier therefore produces a new immutable
source identity instead of silently reusing a stale projection.

Source manifest v2 coverage is one of `full`, `partition`, or `delta`. A delta
Source manifest v3 adds explicit `integrity`, `lineage`, and an optional
`maximum_record_bytes` parser ceiling to v2 typed coverage. Integrity always
contains the locally computed SHA-256 and may also carry a source-bound provider
checksum. Lineage names the direct provider, upstream datasets, transformations,
and a conservative independence group. A missing legacy lineage serializes as
unknown and never becomes evidence of independence.
Coverage is one of `full`, `partition`, or `delta`. A delta
names its exact base, positive consecutive sequence, and superseded source IDs.
A full source cannot compose with active partitions. Overlap, gaps, cycles,
missing bases, cross-provider supersession, and mixed legacy/typed frontiers fail
the build.
Generation v3 uses `runtime_layout: "compact-v1"`. Its local SQLite database keeps
the selected source manifests, active facts and projections, review/policy state,
and the evidence needed by runtime queries. Each complete source history is first
written to an external JSONL object. The receipt binds its SHA-256, length, source,
record/fact counts, selected state, attribution digest and coverage digest.
`verify-audit` re-hashes and parses every object before an audit export or retention
checkpoint. The separate retention signature namespace is
`argand-site-registry-audit-retention`; every checkpoint contains
`deletion_authorized: false`. Generation v2 remains supported with embedded
history for compatibility.
The normal export emits selected active facts only and excludes rejected facts.
Every assertion has `selection_state: "active"`. Audit export includes active,
superseded, and rejected facts; rejected assertions include their reason. Both

## 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.

# Version 0.5 security review
Date: 2026-09-13. Scope: all changes from signed version 0.4.0 through the 0.5
implementation, including source manifest v3, ROR ZIP acquisition/import, streamed
Wikidata JSON, compact generations, external audit bundles, retention signatures,
evaluation lineage, benchmark tooling, dependencies and operator documentation.
No unresolved critical, high, or medium-severity finding remained at release
validation. This is a source review and adversarial test result, not a claim that
an imported URL is safe or that a future public registry has been reviewed.
## Boundaries reviewed
- Provider responses, manifests, JSON/CSV/XML/ZIP/archive members, source records,
names, URLs, lineages and audit-store entries are untrusted input.
- A source assertion cannot authorize a route. Name, edge and equivalence authority
still comes from policy-qualified reviewer signatures; release authority remains
a separate publisher signature and activation step.
- The cache, writer, audit store, reviewer trust file and keys are operator-owned
local resources. Consumer trust starts with an independently obtained receipt
pin or publisher trust root.
- The project ships no hosted API, browser rendering surface, credential store,
production key, preapproved dataset, automatic signer, or automatic activation.
## Findings fixed
| ID | Severity before fix | Resolution |
| --- | --- | --- |
| SR-05-01 | Medium | Audit-store discovery previously used the 512 MiB fact-line ceiling for an untrusted unmatched header. Header reads now stop at 1 MiB before JSON materialization; facts remain bounded and content-authenticated. |
| SR-05-02 | Medium | SQLite can auto-rollback a transaction on `SQLITE_FULL`; an unconditional second rollback could return before cleanup and leave a committed incomplete checkpoint. Recovery now detects autocommit, always attempts source discard and growth-ceiling restoration, and has a real growth-cap regression. |
| SR-05-03 | Medium | A syntactically valid compact receipt could omit a selected audit reference while still naming other bundles. Opening now validates every source declaration, exact PSL identity, receipt-to-database selected-source equality, and exact equality between selected bundle references and active receipt sources. |
| SR-05-04 | Medium | Initial ROR ZIP limits trusted member size metadata. JSON and CSV decompression now have independent actual-byte ceilings in addition to record, count, database-growth, member-count, compression-method, encryption and name checks. |
| SR-05-05 | Medium | Foreign keys were disabled during an indexed compaction transaction and the first error on rollback could bypass restoration. Every exit now attempts rollback as needed and restores foreign-key enforcement before returning. Publication still requires `integrity_check` and a zero-row `foreign_key_check`. |
| SR-05-06 | Low | The first benchmark stdout cap applied `RLIMIT_FSIZE` to the whole child and could kill SQLite writes. The final runner uses bounded stdout/stderr pipes, kills the isolated process group only on output overflow, records the condition, and never limits dataset/database files. The induced hot journal was recovered and the import resumed to the clean-import totals. |
The review also capped authenticated custom records at 256 MiB so generated cold
bundle lines remain within their verifier ceiling. Removed Wikidata statements
carry their exact superseded source IDs in tombstone exports. ROR inactive and
withdrawn website assertions remain auditable but ineligible.
## Acquisition and archive checks
Source URLs use an HTTPS provider allowlist, reject credentials/fragments/custom
ports and revalidate every redirect. Resumption requires a strong unchanged ETag,
exact final URL, matching total and Content-Range. Downloads have caller-supplied
byte ceilings and immutable completion receipts. Provider checksum evidence is
accepted only for reviewed source-bound locations: the matching Zenodo record for
ROR or the same Wikimedia dump directory for Wikidata. ROR's MD5 is used only to
match Zenodo's published field; the local content identity and all downstream
references use SHA-256.
The ROR reader accepts exactly one version-matched JSON and CSV member, Stored or
Deflated, with no path components, encryption or extra members. It streams schema
2.1 JSON with duplicate-key rejection and fails on unknown top-level fields. Every
source import re-hashes the exact no-follow input descriptor after parsing and
publishes completion only after all records commit.
## Compact history and signing checks
Cold bundles use digest-derived names and are created without replacement. A
reference binds exact bytes, source declaration, selected state, record/fact
counts, coverage and attribution. Verification opens with `O_NOFOLLOW`, checks
length and SHA-256 on the same descriptor, then parses bounded JSONL in required
record-before-fact order. Audit export and retention checkpoint first verify every
object. Retention signatures use the distinct
`argand-site-registry-audit-retention` namespace, and their authenticated document
always requires `deletion_authorized: false`; the software provides no deletion
command.
Runtime compaction occurs only after all bundles are durable and verified. It
uses an indexed exact fact keep-set, commits a deterministic runtime copy, restores
foreign keys, then runs integrity and foreign-key checks before `COMPLETE.json` is
created. Readers authenticate and copy SQLite into a private unlinked file before
opening immutable mode, preserving the existing sidecar and post-open mutation
defenses.
## Automated and manual evidence
- Workspace formatting, locked all-target checks, Clippy with warnings denied,
strict rustdoc, Rust/Python tests, consumer parity, reproducible source packaging
and extracted-source acceptance are release gates.
- `cargo audit --deny warnings` loaded 1,243 RustSec advisories and reported no
finding across 277 locked dependency nodes.
- The repository and diff contain no private key, token, password, dataset,
production review, or generated registry. SQL values remain parameterized;
dynamic SQL fragments are fixed internal table/predicate vocabularies.
- Adversarial tests cover duplicate JSON keys/records, schema/member drift,
symlinks, truncation/substitution, oversized records, malformed coverage,
process termination at multiple checkpoints, SQLite growth exhaustion,
incomplete update/publication, receipt bundle omission, signature tampering,
reviewer/publisher separation, revocation continuity and rollback.
## Residual operator responsibilities
Protect cache, writer and audit directories from untrusted local writers and
replicate cold objects by exact digest. A deliberately configured 256 MiB record
can require comparable memory; choose the smallest inspected limit and enforce
process/storage quotas around provider jobs. Measure cold authenticated startup on
deployment storage, because every registry open copies the full runtime database.
Obtain provider checksums and publisher/reviewer trust roots independently. A valid
hash or signature authenticates bytes and a decision, not ownership, current site
safety, commercial fitness, or reviewer competence. Continue malware/content,
drift, expiry, revocation, backup/restore and incident controls before any public
dataset or Argand route is activated.

# Validation
# Version 0.6.0 Web Graph and updater validation, 2026-09-22
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 repeated audit passed with no findings.
## Version 0.5.0 release and security validation, 2026-09-13
Implementation commit: `557ba7cd6982b02754d34fb99cba5a116f78f153`, signed by
Nic Weyand. Version 0.5 adds the ROR 2.1 adapter, source-bound provider checksums,
explicit source lineage, multiline Wikidata dump and JSON-delta replay, compact
runtime generations with authenticated external audit bundles, signed retention
checkpoints, lineage-aware evaluation reports and a bounded benchmark harness.
Writer stores retain schema version 5; source manifests advance to v3 and compact
generation receipts to v3.
Linux x86_64 with Rust/Cargo 1.98.1 and Python 3.14.7 passed:
- Formatting, locked all-target compilation, Clippy with warnings denied, strict
API documentation, all 70 Rust tests and all 10 Python tests.
- Native CLI, reusable Rust and Python consumer parity across the synthetic
fixture, including trust failures.
- Adversarial checks for ZIP member and expanded-size drift, multiline and large
Wikidata records, P856 tombstones, killed and disk-full imports, audit omission
and substitution, compact/full equivalence, receipt selection mismatches,
retention signatures, benchmark output exhaustion and no-clobber publication.
- `cargo audit --deny warnings` scanned 1,243 RustSec advisories across 277 locked
dependency nodes without a finding. The final security review found no unresolved
critical, high or medium issue in its reviewed scope; see
[SECURITY-REVIEW-0.5.md](SECURITY-REVIEW-0.5.md).
Two source packages from the clean implementation commit were byte identical.
Receipt pin:

Archive SHA-256:
`63a0571061385a36197beabadfd4c29e3d15bb5948570bea74b04cfb3f784abc`.
The receipt verifier accepted both copies. The archive was extracted outside the
repository without Git metadata and passed the complete acceptance gate again.
[Hosted Forgejo Actions run 9](https://git.argand.org/nicweyand/argand-site-registry/actions/runs/9)
passed the exact implementation commit on the isolated registry runner. It fetched
the public revision without credentials, ran the offline acceptance gate, compared
and verified two deterministic source packages, extracted one without Git metadata,
and passed the complete gate again from that source tree. The runner has no dataset,
reviewer, signing or activation authority.
A separate real-provider canary used ROR release `v2.12-2026-08-25` from Zenodo
record `22099990` and the same-day Public Suffix List. The 36,246,232-byte ROR ZIP
had SHA-256
`5779c7baf71771fd8ea829201e7bd4343a3c68ff36c595f480b3a00292f78931`
and provider-bound MD5 `ce8807691455d4ada3216c31408e9e1a`. It expanded to
362,619,018 bytes and imported 137,398 records with 914,439 facts in 62.30 seconds,
using 25,032 KiB peak RSS. Exact replay produced zero changes. A deliberately
killed import resumed from its last committed checkpoint and converged on the same
record and fact totals.
The resulting compact registry contained 137,398 entities, 131,591 properties,
133,398 edges and 169 rejected facts. Its generation pin was
`b4f639e3d4f759833914a34aded2389442eeca142952d78fb7f66343f6f4224d`.
The 824,705,024-byte compact database was 38.69% smaller than the full audit-bearing
database. Two compact builds were byte identical. Full verification covered
686,468,048 audit bytes, 137,399 source records and 914,440 facts. A 1,000-case
evaluation produced 1,000 expected safe abstentions with 72 microsecond median and
96 microsecond p95 lookup latency. These single-machine import and warm-read
measurements characterize this release canary, not production serving capacity;
see [BENCHMARKING.md](BENCHMARKING.md).
The final inventory was reviewed for credentials, private paths, datasets,
generated artifacts, unsafe Rust and unrelated changes. Provider data, generated
registries and audit bundles remain outside Git. No production review or signing
key was used, and no Argand source tree, build cache, service or public route was
changed during implementation or validation.

# ADR 0006: Source lineage and independence
Status: Accepted design; implementation scheduled for 0.5.
Status: Implemented in 0.5.
Corroboration must describe the direct provider, upstream dataset, transformation,
and snapshot. Two providers that copied the same upstream assertion do not count
as independent evidence merely because their URLs differ. Unknown lineage stays
unknown.
Version 0.4 preserves provider-native provenance and never combines popularity or
same-domain evidence into ownership confidence. Version 0.5 will add explicit
lineage fields and independence-aware corroboration without rewriting history.
Version 0.5 adds explicit source-manifest lineage and exposes it in evidence and

# Argand automated high-confidence navigation policy
This generation is a machine-reviewed public navigation directory. It does not
claim two independent human reviewers. The dedicated reviewer identity approves
only exact, unambiguous name and official-site assertions after source evidence
and a fresh bounded endpoint observation are present.
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
two-human-reviewer reference policy remains unchanged and available for
high-risk, disputed, or manually governed catalogues.
