Increment 2, completing the work started in the parent PR. The second implementation of the
virtual-chassis claim-ambiguity rule is now gone.

What changed

family/installed._ambiguous_bases is deleted. Installed-family discovery passes the complete
historical base relation to resolve_template_claims, the primitive the parent PR added.
_source_bases no longer owns a uniqueness check; it assembles the template's own base and the
accepted historical bases.

Module context is threaded through flat_family_bases, flat_family_candidates and
_flat_candidates. Both entry points, plan_installed_families and plan_module_conversions,
already received it.

The behaviour change

This path was silent. An ambiguous historical claim was dropped with no record, so an operator
whose family stopped being offered after a virtual-chassis renumber had nothing to read. It now
warns through the module's own logger, naming the competing templates, with the same wording the
engine path uses.

Behaviour deliberately preserved

A template's current resolved base is still yielded unconditionally and still precedes the accepted
historical base. Only historical bases are subject to ambiguity rejection. Feeding current bases
through the filter would stop offering valid families.

_historical_bases keeps its extraction behaviour, including the backreference for a repeated base.

_singly_claimed counts member primary keys across complete family candidates. It is a different
rule and is untouched.

Verification

958 passed, 16 skipped, coverage 98.02%.

Two new assertions cover the previously silent path, both against real ORM scenarios: an ambiguous
family base warns and is not offered, and an unrelated template whose single claim does not collide
still survives. Suppressing the warning fails both while the other 32 drift tests pass.

test_family_dependency_direction.py and test_module_boundaries.py pass unchanged, with no new
permitted-exception entry.

Summary by CodeRabbit

  • Bug Fixes
    • Improved handling of conflicting historical interface-family base claims.
    • Preserved valid current and historical bases while rejecting ambiguous claims.
    • Ensured unrelated families remain convertible when another claim conflicts.
    • Added warning messages when ambiguous historical claims are detected.
    • Aligned installed-family discovery and conversion behavior for more consistent results across family conversions.

Walkthrough

Installed-family discovery now uses the shared TemplateClaim resolver for historical bases. Module context flows through family candidate and conversion planning. Tests verify warnings, ambiguous-family exclusion, and unrelated-family conversion.

Merge Risk: 🟡 Moderate · up to 626d4

Family-base ambiguity handling emits a mislabeled warning and can fail the new assertion for multi-base templates. The ADR header requirement also remains unresolved, so these should be addressed before merge.

A rabbit checks each family claim,
Shared rules now resolve the same.
Ambiguous bases raise a light,
Unrelated families pass just right.
Module context hops through the chain,
And tests confirm the new refrain.

Update the ambiguity description.

resolve_template_claims also rejects every historical base from one template when that template has multiple historical labels. Lines 87-88 describe only bases claimed by multiple templates. Document both rejection cases.

Resolve the complete historical base relation through the shared primitive. Emit collision warnings from the installed-family logger with module context.

Keep current bases unconditional and preserve ordering and duplicate handling. Keep member uniqueness separate. Update ADR 0013 to describe both callers.

Confirm the warning test fails before the change. Add an ORM case for overlapping claims with an unrelated survivor. Validation: 958 passed, 16 skipped, 298 subtests passed; coverage 98.02%. Ruff lint and format checks pass.
Document that a base claimed by multiple templates is rejected. Also document that all historical bases of a template with multiple claims are rejected.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use label_kind for multi-label warnings.

flat_family_bases passes label_kind="family base". A two-base matcher reaches the len(labels) > 1 branch, which currently emits Interface template; the test can therefore fail its Family base assertion. Compute subject before the claimant loop and use it in that warning.

Proposed fix
+    subject = "Interface" if label_kind == "interface name" else "Family base"
     for claim in claims:
...
-                f"Interface template {claim.template_name!r} of {module} could name any of {sorted(labels)} "
+                f"{subject} template {claim.template_name!r} of {module} could name any of {sorted(labels)} "
...
-    subject = "Interface" if label_kind == "interface name" else "Family base"
