fix(OMN-16239): resolve ProjectionTableTarget schema through physical mapping at SQL emission

[jonahgabriel]

OMN-16239 — ProjectionTableTarget.schema bypassed physical_schema_mapping

ProjectionTableTarget carried the raw contract schema straight into the schema-qualified SQL built by _execute_upsert/_execute_query, while the grant check ran the same declaration through physical_grant_schema_for_table(). For every relation still under the OMN-15359 physical-relocation bridge the two disagreed: grant validation passed against the physical schema while the statement that actually executed named the declared one.

This was live, not latent

Probed the stability-test lane's omnidash_analytics (2026-08-19, read-only information_schema query):

Fact	Value
Non-system schemas present	information_schema, omninode_internal, public — no tenant schema exists at all
Relations in omninode_internal	1 (live_events, the single family copied out by migration 099)
Relations in public	71, including delegation_events, capsule_store, llm_call_metrics, node_service_registry, swarm_runs, traces

A scan of every db_io.db_tables declaration across omnibase_infra, omnimarket, omniintelligence, and omnibase_core found 39 node contracts whose declared schema differs from the physical mapping (13 tenant-domain, 26 omninode_internal-domain). Pre-fix, every one of them emitted SQL against a schema that resolves nowhere: the tenant ones against a schema that does not exist, the internal ones against a schema holding only live_events. hook_events (OMN-16090) was simply the first to be noticed, and was worked around by flipping its contract to public — a truth-telling workaround, not this root fix.

This is the same failure class physical_schema_mapping.py's own header comment already recorded from OMN-15426's live readback ("handler_wiring issues schema-qualified SQL against omninode_internal for these relations while they resolve nowhere").

Mechanism of the fix

_resolve_projection_database_target now resolves the physical schema exactly once per table and feeds both consumers from that single value:

• it is threaded into _projection_operation_bindings → _require_projection_binding_privileges as grant_schema, replacing that function's own second resolution;
• it is stored on the target and is what both SQL emitters qualify with.

Divergence is now structurally impossible rather than two call sites that happen to agree. The field is renamed schema → physical_schema, parallel to the existing physical_database, so every consumer is explicit about which of the two schemas it wants — the rename is what makes the ambiguity that caused this bug non-recurring. The declaration stays available and logical on target.table.schema, which domain resolution and the contract-facing access refusals continue to use.

Degrades to a no-op. Once OMN-15359 copies each family out, its table leaves the bridge set, physical_grant_schema_for_table returns identity, and physical_schema == table.schema. live_events is already in that post-migration state and is asserted in the tests as the live control.

Seams (define-and-match-seams rule)

Boundary: contract schema value → physical mapping → emitted SQL, field by field.

Seam point	Type / shape	Value for a bridged table	Value post-OMN-15359
ModelDbTableDeclaration.schema (contract YAML)	str, logical domain schema	"tenant"	"tenant"
physical_grant_schema_for_table(schema, table_name)	(str, str) -> str, total, keyed on schema + bare table name	"public"	"tenant" (identity)
ProjectionTableTarget.physical_schema	str, single resolution point	"public"	"tenant"
_require_projection_binding_privileges(grant_schema=…)	str kwarg, passed in, not re-resolved	"public"	"tenant"
ProjectionDatabaseTarget.physical_schemas	tuple[str, ...]	("public",)	("tenant",)
_execute_upsert emitted SQL	INSERT INTO "{physical_schema}"."{table}"	"public"."delegation_events"	"tenant"."delegation_events"
_execute_query emitted SQL	SELECT * FROM "{physical_schema}"."{table}"	"public"."delegation_events"	"tenant"."delegation_events"
ProjectionTableTarget.domain	EnumDatabaseSchemaDomain, derived from table.schema (logical) — deliberately unchanged	TENANT	TENANT

The grant-check column and the emitted-SQL columns are now the same value by construction. The cross-boundary regression test drives the real SQL-emission path and asserts on the emitted string, so the seam is covered by a test that exercises it rather than two independent unit suites.

Tests — RED before / GREEN after

New file tests/unit/runtime/auto_wiring/test_projection_physical_schema_sql_emission_omn16239.py, driving a genuine _execute_upsert/_execute_query call against a DB-API double whose cursor records the statement (not a mock of the resolution itself):

• test_bridged_tenant_table_is_still_declared_bridged — premise guard, fails loudly if OMN-15359 relocates these families so the SQL assertions can never pass vacuously
• test_upsert_sql_names_the_physical_schema_for_a_bridged_tenant_table
• test_upsert_sql_names_the_physical_schema_for_a_bridged_internal_table
• test_query_sql_names_the_physical_schema_for_a_bridged_internal_table
• test_grant_check_and_emitted_sql_resolve_to_one_schema — the seam itself
• test_unbridged_table_keeps_its_declared_schema_so_the_fix_degrades_to_a_noop — live_events control

At merge-base fa3c706faa4c98ada3c1c05a95776249fff0100c: 5 failed, 1 passed (the premise guard). Representative failure showing the live bug verbatim:

E   assert False
E    +    where <method 'startswith' of str> = 'SELECT * FROM "omninode_internal"."generation_events"'.startswith

At head 9356a4e7f1d7705aeff8753715faa3d942018cc2: 6 passed.

Four existing tests encoded the old behavior and were corrected

Not "changed to pass" — each asserted SQL against a schema that does not physically hold the table:

• test_projection_domain_adapters.py::test_red_control_nonlocal_tenant_guc — asserted INSERT INTO "tenant"."delegation_events"
• test_projection_dispatch_tenant_authority_context.py::test_dispatch_engine_keeps_verified_authority_out_of_band — same string
• test_projection_dispatch_tenant_authority_context.py::test_mixed_target_internal_operation_does_not_resolve_tenant_authority — asserted "omninode_internal"."generation_events"
• test_typed_db_io_loading.py (2 tests) — .schemas assertions; now assert the declared and physical values so the seam stays visible

The remaining edits are the mechanical .schemas → .physical_schemas rename in the two service-database topology tests and the live_events integration test (all identity-mapped, values unchanged).

Gates

Gate	Result
ruff format + ruff check	clean
mypy --strict (both touched source files)	Success: no issues found in 2 source files
Full unit suite tests/unit -n auto	23,528 passed, 40 skipped, 0 failed (127s)

Pre-push governed selector (OMN-13973)	escalated to full suite — 23,528 passed (586s), "impacted tests passed; allowing push"

Gates ran on stickybeatz-studio (the .200 gate host), which is this session's host — rule 11a satisfied without patch-transfer, so the edit-locality trap does not apply.

Follow-up (DoD bullet 3)

The 39 affected contracts are confirmed affected but are not repaired here — this PR fixes the resolution path so their declared logical schemas become correct-by-construction, which is the root fix. No contract flips are needed and hook_events' existing public workaround (mkt#2103 / infra#2787) can be reverted to its logical schema once this lands; that revert is filed separately rather than bundled.

Closes OMN-16239.

📝 Walkthrough

Walkthrough

Projection targets now retain declared schemas and store resolved physical schemas separately. Schema resolution occurs once during target construction and is reused for privilege checks, SQL generation, diagnostics, and schema aggregation.

Changes

Projection schema resolution

Layer / File(s)	Summary
Target schema resolution src/omnibase_infra/runtime/auto_wiring/handler_wiring.py	ProjectionTableTarget stores physical_schema, while table.schema retains the declared schema. Binding selection and privilege checks reuse the resolved value.
Physical schema SQL and diagnostics src/omnibase_infra/runtime/auto_wiring/handler_wiring.py	Upsert and query SQL use physical schemas. Access-denial messages use declared schemas. Adapter diagnostics use physical_schemas.
Schema resolution validation tests/unit/runtime/auto_wiring/*, tests/integration/runtime/*, tests/unit/topology/*	Tests cover bridged and unbridged tables, SQL qualification, privilege alignment, physical-schema aggregation, and renamed target properties.
Tenant projection proof alignment docker/domain-adapter-proof/prove.py, tests/fixtures/application_relation_ownership/topology.yaml	The proof uses future_tenant_projection, and the topology fixture grants its tenant projection writer SELECT, INSERT, and UPDATE privileges.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to d2c2a

The domain-adapter proof path currently depends on an absent topology file and missing environment initialization before database access. Until those prerequisites are supplied, the changed schema-routing behavior cannot be reliably validated, so merge should wait for this bounded readiness issue to be fixed.

Complete the proof prerequisites.

This proof currently cannot run reliably because prove.py loads docker/domain-adapter-proof/topology.yaml, but that file is absent, and the compose entrypoint does not source ~/.omnibase/.env before the first database connection. Add the topology and required grants, then initialize the environment before PostgreSQL operations.
