rolandpg · 2026-04-28T16:20:36Z

Summary

Implements the scaffold for RFC-0001: ZettelForge OSINT Layer.

29 files touched — all new; no existing logic modified.

What changed

New entity types (Phase 1–5)

Phase 1 (Infrastructure): ASNumber, Netblock, MXRecord, NSRecord, Port, Website, WebTitle
Phase 2 (People): PhoneNumber, TwitterAffiliation, Hashtag, Alias, NamechkResult
Phase 3 (Technical): BuiltWithTechnology, BuiltWithRelationship, CertificateSubject, SSLPoint
Phase 4 (Social/Financial): Tweet, StockSymbol, Sentiment
Phase 5 (Physical): GPS, CircularArea

New edge types

Infrastructure: resolves_to, hosts, ns_for, mx_for, owned_by, part_of_as, delegated_to, receives_mail_on, listens_on, associated_with
People: has_phone, affiliated_with, located_at, has_handle, verified_on, uses_platform, hashtags, mentions
Technical: powered_by, powered_by_relationship, issued_cert, terminates_tls, has_certificate
Social/Financial: posted_by, contains_hashtag, links_to, traded_as, exhibits_sentiment
Physical: located_near, within_radius

New files

— Phase 1–5 entity and edge declarations
— self-registering async collector catalog
— canonical key normalisation (IPv4, Domain, Phone, ASN, Netblock)
— named investigation scoping with owner/ACL/classification
— 14 collector stubs across infrastructure/, people/, tech/, social/, breach/
— entity schema tests
— registry and investigation tests
— implementation summary doc

Modified files

— re-exports

Reviewer notes

All Python files pass validation
Collectors are stub implementations; real API calls (python-whois, dnspython, BGView, crt.sh, etc.) are wired but require their respective packages/API keys to execute
Port scanner is gated behind active-scan documentation; does not run passively
MTZ export (Maltego) is ; deferred to a future phase

Pull request overview

Adds a new zettelforge.osint subpackage that scaffolds the RFC-0001 OSINT Layer: an OSINT ontology (entities/edges), a self-registering async collector registry, canonical entity key normalization, and an in-memory “Investigation” case-scoping API, plus tests and a short RFC doc.

Changes:

Introduces OSINT ontology declarations (Phase 1–5) and an async collector registry (TRANSFORM_REGISTRY) with multiple collector stubs.
Adds canonicalization utilities (IPv4/domain/phone/ASN/netblock) and an in-memory investigation store with JSON export.
Adds initial test coverage for ontology shapes, registry presence, and canonicalization behavior; adds RFC documentation.

Replaces the original Phase 1-5 scaffold commit (830156f) with an implementation that integrates with the existing ontology validator and ships working Phase 1 collectors with mocked tests. What changed vs the original scaffold: - ontology.py: Phase 1-5 entity / edge declarations, all using the from_types/to_types/cardinality shape that OntologyValidator actually validates against. The scaffold's "from": "*", "to": "A|B" syntax was invisible to the validator and silently waved every relation through. - ontology.py: canonicalization helpers (asn, cidr, domain, ipv6, mx, port, url, web_title) used by collectors and tests. - ontology.py: merge_into_global_ontology() — idempotent merge into core ENTITY_TYPES / RELATION_TYPES at import time, no schema migration. - transform_registry.py: function-based register(metadata, fn) API, CollectorTuple NamedTuple, idempotent re-registration. Scaffold used a decorator pattern with no idempotency. - collectors are sync (matches existing yara/sigma pipelines; the codebase has zero asyncio usage today). Scaffold used async def. - Phase 1 collectors are functional with mocked tests: dns_collector — A/AAAA/NS/MX with NXDOMAIN/Timeout absorbed whois_collector — domain via python-whois, IP via ipwhois RDAP (graceful ImportError handling per AGENTS.OE Override 4 — surface failures, no silent retry) cert_collector — crt.sh SAN enumeration, dedup, HTTP error → [] - Phase 1.5 collectors (bgp_collector, port_scanner) and Phase 2-5 stubs (Hunter, Holehe, Namechk, Wappalyzer, BuiltWith, Twitter, Hashtag, HIBP, Breach Directory) register their metadata so discovery works, return [] until their integration ships. port_scanner is gated behind ZETTELFORGE_OSINT_ACTIVE_SCAN=1. - IPv6Address added to core ENTITY_TYPES (parity with IPv4Address). - Top-level __init__.py: side-effect import of osint subpackage. The original scaffold's __init__ called __all__ += [...] before __all__ was defined — would have raised NameError on import. - Tests: 67 mocked tests in tests/test_osint_entities.py + tests/test_osint_collectors.py covering entity validation, edge validation, canonicalization, collector shape, registry dispatch. - docs/rfcs/RFC-016-osint-layer.md: canonical RFC with Status block documenting the three deviations from the literal RFC text (single kg_nodes table, no CLI in this PR, sync collectors). - SCOPING_DOC.md: Phase 1 planning notes. - docs/rfc-0001-osint-layer.md (scaffold) removed; docs/rfcs/RFC-016 is the canonical doc. Verification: - 67/67 osint tests pass (0.12s) - 121/121 focused subset (basic + kg_edge_schema + extensions + consolidation + osint) pass (3.71s) - ruff check src/zettelforge: clean - ruff format --check src/zettelforge: clean - Smoke import: 14 collectors registered, all entity/edge types merged. Out of scope (deferred): - Real BGPView / Wappalyzer / Hunter / etc. integrations (Phase 1.5+) - Investigation workflow engine + state machine (Phase 4) - Top-level zettelforge CLI (Phase 4 brings it alongside the workflow engine) - Container packaging (RFC §10 already defers to vNext per docs/03) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Addresses the two CI failures from ecb3f12: - 3 dns_collector tests failed with ModuleNotFoundError: No module named 'dns'. The tests use dns.resolver.NXDOMAIN to construct realistic mocks; that requires dnspython to actually be installed even though the collector calls themselves are mocked. Adds a new [osint] optional dependency with dnspython, python-whois, and ipwhois (the runtime Phase 1 collectors need them anyway), and pulls it into [dev] so CI's pip install -e .[dev] resolves them. - Total coverage was 66.74% vs 67% required (GOV-007). The OSINT layer added ~720 statements with most stub branches uncovered. Adds three parametrized tests over every registered collector: 1. unsupported input returns a list (covers early-return) 2. metadata is well-formed (covers TransformMetadata fields) 3. every declared input_type is callable without raising That is 14 collectors x 3 tests = 42 new tests, all using mocked or short-circuited paths (no network, no API keys). Local results: - 109/109 osint tests pass (was 67; +42 from parametrized smoke tests) - ruff check src/zettelforge/osint: clean - OSINT package coverage: 70% (was untested for stubs) No force-push needed; this is a follow-up commit on rfc/osint-layer-scaffold. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

The new universal smoke test test_every_collector_handles_each_declared_input_type[whois_collector] exercised whois_collector with the canonical RFC 5737 documentation IP 192.0.2.1, which ipwhois treats as a poisoned input and raises IPDefinedError before any network call. The collector wasn't catching that exception, so the bare-bones probe call propagated it and CI failed again on test (3.12) and test (3.13). Real callers will hit the same exception any time an analyst feeds in a private (10/8, 192.168/16), loopback (127/8), or documentation-net IP. The right behaviour is fail-closed: log and return None / [] so the KG doesn't pretend it has data it doesn't. This commit catches IPDefinedError and BaseIpwhoisException in _lookup_ip, logging the reserved-IP case at debug and the broader failure case at warning. Per AGENTS.OE Override 4, the failure is surfaced (not silently retried) — it just doesn't bubble as an exception. Local: 109/109 osint tests pass; ruff clean.

Addresses reviewer concerns on PR #147 that survived the amend (the rest were against scaffold code my amend already replaced). bgp_collector edge direction inverted: The ontology declares part_of_as as Netblock -> ASNumber (with IP families also valid as the from side). The collector was emitting from_entity_type="ASNumber", to_entity_type="Netblock" which inverts the declared direction. validate_relation would have rejected those edges. Swap the from/to fields; the entity emitted is still the Netblock (semantically: "given an ASN, here are netblocks that are part_of_as that ASN"). Caught by Copilot review of the original scaffold; the bug carried over into my amend. entity_resolver canonicalise_ipv4 leading zeros: ipaddress.IPv4Address("001.002.003.004") raises AddressValueError on Python 3.10+. Replace with explicit octet parsing (split on '.', int() each, validate 0-255). Raises ValueError on malformed input instead of silently corrupting it. entity_resolver canonicalise_asn hex strip: Old behavior stripped non-digits, so "0x3039" became "AS03039" rather than the expected hex-decoded value. Delegate to zettelforge.osint.ontology.canonicalize_asn which uses int() and raises ValueError on non-decimal input — fail-loud. entity_resolver._canonical_key used "Domain" (typo, scaffold relic): The core ontology uses DomainName. Fix to match. Also added IPv6Address case (parity with IPv4Address). entity_resolver late `from datetime import datetime` at module bottom: Moved to module-top imports. Same module: phone canonicalization preserved as-is (E.164 best-effort heuristic; documented now). Netblock canonicalization upgraded to use canonicalize_cidr so host bits get trimmed. Local: 109/109 osint tests pass; ruff clean. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Reviewer notes — addressing the bot reviews

The 32 unresolved threads were filed against scaffold commit 830156f which has been replaced. Audit summary:

Live concerns now fixed:

bgp_collector edge direction inverted vs ontology (part_of_as is Netblock → ASNumber, not the reverse) — fixed in b6d35cd.
entity_resolver.canonicalise_ipv4("001.002.003.004") raised AddressValueError — fixed with explicit octet parsing.
entity_resolver.canonicalise_asn("0x3039") silently produced AS03039 — fixed; delegates to ontology.canonicalize_asn which raises ValueError.
entity_resolver._canonical_key used "Domain" (scaffold typo) — corrected to "DomainName"; added IPv6Address case.
Late from datetime import datetime at file bottom — moved to top.

No-longer-applicable concerns (scaffold code replaced wholesale by ecb3f12):

All except Exception: pass blocks across collectors (dns/whois/cert/holehe/twitter/hashtag/builtwith/wappalyzer/cert/breach_directory/hibp/social/tech): Phase 1 collectors now catch specific exceptions (e.g. dns.resolver.NXDOMAIN, httpx.HTTPError, BaseIpwhoisException) and emit structured logs. Phase 2-5 stubs short-circuit on missing API keys before any try/except.
Unused imports (json, re, tempfile, asyncio, Any, field, double-import of TRANSFORM_REGISTRY): all gone in the amend; ruff clean across src/zettelforge/osint.
holehe_collector blocking subprocess.run in async context: collector is now sync (matches codebase) and a stub.
wappalyzer_collector blocking urllib.urlopen in async: collector is now sync stub.
__all__ += before __all__ defined: fixed; top-level __init__.py uses from zettelforge import osint (side-effect import).
Collectors not auto-imported, registry empty on import: osint/__init__.py now imports each subpackage (infrastructure, people, tech, social, breach) at package-load time. Verified: 14 collectors register on import zettelforge.
Tests assume registry populated without import: tests now import zettelforge.osint as _osint to trigger registration.
Collectors emit undeclared types (TXTRecord, PasteEntry, BreachEvent, etc.): scaffold collectors emitting those have been replaced; current Phase 1 collectors emit only types declared in the ontology. Stubs return [] until their phase ships.
port_scanner not actually gated: now gated behind ZETTELFORGE_OSINT_ACTIVE_SCAN=1 env flag with explicit check before any nmap call.
breach_directory query not URL-encoded: rewritten as a stub; URL construction will be added with the live integration.
hibp_collector "k-anon" claim mismatched with email-in-URL behaviour: rewritten as a no-network stub; the k-anon flow lands when the live integration does.
docs/rfc-0001-osint-layer.md broken link to RFC: file removed; canonical RFC is docs/rfcs/RFC-016-osint-layer.md.
pytest "unused" in test files: pytest IS used (parametrize, fixture, raises). Stale flag against the scaffold tests, not the current ones.

I'll resolve the stale threads next. Re-reviews welcome on the live HEAD (b6d35cd).
