What

Exchange address rules and AD↔cloud sync, as vocabulary. There is no executor here; lance-graph #1392 computes the violations.

AD holds a remote mailbox's addresses as:

• proxyAddresses: SMTP:{primary}, smtp:{secondary}, smtp:{alias}@{tenant}.mail.onmicrosoft.com;
• targetAddress: SMTP:{alias}@{tenant}.mail.onmicrosoft.com.

Exchange Online shows the same set as PrimarySmtpAddress and EmailAddresses. The alias is mailNickname.

Contract

• exchange::AddressTemplate: numbered placeholders {0}, {1}, …, in order and separated by non-empty literals; the multi-value sibling of ogar_dir_core::label::LabelPattern.

  • render(values) substitutes them.
  • matches(s) returns the non-empty values, which render back to exactly s by construction.

• exchange::ROUTING is {0}@{1}.mail.onmicrosoft.com. routing_parts(addr) returns (alias, tenant), and only for an address with a single @ and a single-label tenant.

• Violation gains three variants plus AddressRole (Upn, PrimarySmtp, SecondarySmtp, Mail, Routing):

  • AddressConflict { key, holders: [(node, role)] }. UPN, SMTP, mail and routing addresses share one key space. A UPN or SMTP address that is another object's SMTP, mail or routing address conflicts. So does a mail held by another object, for example an admin account with mail set as a password-reset target but no mailbox. Same-attribute collisions stay DuplicateSmtp / DuplicateUpn. One object holding an address under several attributes is not a conflict.
  • RoutingNotInProxies { node }: a remote mailbox must own its routing address as an SMTP proxy.
  • RoutingMismatch { node }: the routing address must be ROUTING for the node's own mailNickname.

• ogar_az::SYNCED (SyncedAttribute, SyncTransform, cloud_of) maps AD attributes to their cloud names, among them:

  • physicalDeliveryOfficeName → officeLocation;
  • userAccountControl → accountEnabled (combined by effective_active);
  • mS-DS-ConsistencyGuid → onPremisesImmutableId (base64);
  • extensionAttribute → onPremisesExtensionAttributes (the bag, below);
  • plus the onPremises* evidence.

  The cloud object id is the record identity, not a mapped attribute.

• onPremisesExtensionAttributes is a bag. Graph returns one object of fifteen extensionAttributeN keys; AD stores fifteen separate attributes.

  • Both land in one pooled slot of the new AttrKind::Bag. Member n is extensionAttribute(n+1), an empty member is absent, and a bag with no values sets no slot.
  • Member names are not stored, so the AD and Graph bags are byte-identical and the pair syncs Same.
  • Read a member with ValuePool::bag_member(r, n): 1-based, BAG_LEN = 15.
  • ogar-ad refuses a multi-valued member, and no longer reports members 1–15 as ignored.

• Schemas:

  • ogar-ad v4 adds physicalDeliveryOfficeName, and v5 adds the extensionAttribute bag.
  • ogar-az v2 requests onPremisesExtensionAttributes.

• Already ingested. onPremisesSamAccountName and onPremisesDistinguishedName already come in. The DN's OU path (leaf CN and DC dropped, root first) goes into the shared OU dictionary, so a synced user's ou_hhtl equals its AD object's (shared_onprem_dictionary_aligns_ad_and_az_hhtl).

Merge order

This PR does not break lance-graph:

• lance-graph only constructs Violation values and never matches on them exhaustively.
• It never matches on AttrKind.
• Its one schema-version check is >=.
• No struct it builds gained a field.

lance-graph #1392's lance-graph-dir-sim suite passes against this head. #1392 needs this PR merged first.

Tests

The workspace passes 1006 tests; fmt and clippy -D warnings are clean.

• the_routing_template_renders_and_matches_alias_and_tenant, a_template_needs_numbered_placeholders_in_order_with_separators.
• ogar-az every_synced_attribute_exists_on_both_sides_once: every pair names a real attribute in both schemas, each side is mapped once, and the routing address is not synced.
• ogar-ad the_office_is_kept_raw.
• ogar-az the_extension_attribute_bag_matches_ad: positional members, null as absent, byte-identical to the AD bag, no slot when all null, v2 requests it and v1 does not.
• ogar-ad extension_attributes_are_one_bag: members 15 and 3, members 16 and 0 not in the bag, a multi-valued member refused, no slot when none set.
• select_is_derived_from_the_schema now checks every schema version against the attributes that existed by then. It used to hardcode "all attributes at v1", and failed when the bag arrived at v2.

Disable runs, each red then green:

AD multi-valued member takes the first value	same
AD bag members reported as ignored	same
bag_member returns an empty member	same
bag_member 0-based	same

Two findings from writing the tests:

• A real bug. The test caught a@b@contoso.mail.onmicrosoft.com parsing to tenant b@contoso; the tenant is now checked for @ too.
• A dead check. Disabling the template's render-back check stayed green, because the property holds by construction. The check was removed and the doc says why.

Open

• Tenant consistency (one tenant per directory) is not a violation yet.
• lance-graph does not read the bag yet; it has no observed field for it.

📝 Walkthrough

Walkthrough

The change adds pooled extension-attribute bags to AD and Graph schemas, defines AD-to-cloud attribute mappings, and adds routing-address parsing and address-related violation types to the directory simulation crate.

Changes

Extension-attribute ingestion and sync mappings

Layer / File(s)	Summary
Shared bag contract and AD ingestion crates/ogar-dir-core/src/schema.rs, crates/ogar-dir-core/src/pool.rs, crates/ogar-dir-core/src/lib.rs, crates/ogar-ad/src/lib.rs, crates/ogar-ad/tests/main.rs	The core defines pooled bags with 15 positional members and adds member lookup. The AD schema adds physicalDeliveryOfficeName and an extension-attribute bag. The encoder gathers numbered members into the bag and reports invalid UTF-8 or duplicate values. Tests cover the office attribute and bag behavior.
Graph schema and AD-to-cloud mappings crates/ogar-az/src/lib.rs, crates/ogar-az/tests/main.rs	The Graph schema adds onPremisesExtensionAttributes in version 2. Public declarations define AD-to-cloud mappings and transforms. Tests check mapping entries and schema-version-based selection.
Graph bag encoding and validation crates/ogar-az/src/lib.rs, crates/ogar-az/Cargo.toml, crates/ogar-az/tests/main.rs, docs/DIRECTORY-SIMULATION-POC.md	The Graph encoder stores numbered extension attributes as a bag when at least one member is nonempty. Tests compare its encoding with the AD bag encoding. Documentation describes the bag representation and ingestion changes.

Routing addresses and violations

Layer / File(s)	Summary
Routing-address template and parsing crates/ogar-dir-sim/src/exchange.rs, crates/ogar-dir-sim/src/lib.rs	The simulation crate adds validated address templates and routing-address parsing. Tests cover rendering, matching, and invalid templates or addresses.
Address roles and violation types crates/ogar-dir-sim/src/violation.rs, crates/ogar-dir-sim/src/lib.rs, docs/DIRECTORY-SIMULATION-POC.md	The crate adds address roles and violation variants for cross-attribute conflicts, missing routing proxies, and routing mismatches. Documentation describes the address rules and related sync mappings.

Change: Feature

Suggested reviewers: claude

Merge Risk: 🔵 Low · up to cd552

An unusual AD attribute name can interrupt ingestion, and the bag documentation could lead callers to select the wrong member. Both corrections are localized; the PR is mergeable with owner awareness and follow-up.

Reject invalid tenant labels in routing_parts.

If the tenant contains a space, routing_parts("alice@bad tenant.mail.onmicrosoft.com") returns Some. That tenant is not a DNS label. Validate the tenant as a DNS label, rather than excluding only @ and ., and add a malformed-tenant test.

Give objectSid an explicit representation transform.

SyncTransform::OnPremisesEvidence describes a copied value, but AD objectSid is binary and Graph onPremisesSecurityIdentifier is a SID string. A byte-for-byte copy cannot produce the declared Graph value. Add a binary-SID-to-string transform instead of labeling this pair as copied. (learn.microsoft.com)

Recognize numbered extension attributes in cloud_of.

If a caller passes the ingested AD name extensionAttribute7, cloud_of returns None. SYNCED contains only the synthetic bag name extensionAttribute. Map valid numbered names to that bag entry so the public lookup covers the attributes it describes.
