test(kv): cover the KV credential seam — kv_config + credentials (→100%) by seonghobae · Pull Request #77 · ContextualWisdomLab/contextual-orchestrator

seonghobae · 2026-07-30T04:37:52Z

Summary

The KV seam through which the cost/routing hub reads config and provider secrets (the AGENTS.md "KV, not env" rule — never os.getenv at runtime) was only exercised incidentally by other suites, leaving its own surface undertested. This PR brings both halves of the seam to 100% with two focused, dependency-free test files (small fakes / monkeypatch — no Postgres or pg_llm_batch install needed).

`kv_config.py` — 49% → 100% (`tests/test_kv_config.py`, 13 tests)

InMemoryConfigStore — seed loading, get/set roundtrip + default, get_category returns a non-aliasing copy, show_config sorted ordering, and the set_secret/get_secret/require_secret surface (secrets stay out of show_config; require_secret raises KeyError when absent).
PostgresConfigStoreAdapter — get/set delegation; get_secret/require_secret with and without a backing secret store (default vs. KeyError, swallowing a backing-store error to the default).
get_config_store — the no-DSN in-memory selection path, seeded and unseeded.

`credentials.py` — 83% → 100% (`tests/test_credentials_backend.py`, 8 tests)

PostgresCredentialBackend — raises NotConfigured on an empty bootstrap DSN or passphrase; stores both (lazy schema) when valid.
from_env — builds from exactly the two bootstrap-transport env vars, and fails loudly when the DSN is unset (no silent empty backend).
_select_backend — memory default (case-insensitive), the postgres branch routes through from_env, and an unknown selector raises.

The live pgcrypto/psycopg methods (_connect/get/set) require a real Postgres and remain # pragma: no cover, unchanged.

Verification

coverage run --source=contextual_orchestrator.kv_config,contextual_orchestrator.credentials → both files 100% (was 49% / 83%).
Full suite: pytest tests -q → 321 passed (was 300).

Scope

Test-only. No production code, dependency, or workflow changes — this locks the security-relevant KV/credential bootstrap boundary under test. Every added test function/class carries a docstring, so the interrogate docstring gate (≥80) is unaffected.

Note: the repo's SAST Semgrep check is currently red on the base branch (5 pre-existing findings in cost_ledger.py/orchestrator.py, already remediated by the in-flight PRs #74/#75) — this test-only diff introduces zero Semgrep findings and will pass once the base fix lands.

`kv_config.py` is the KV seam the cost/routing hub and `credentials.py` read config and provider secrets through (never `os.getenv` at runtime), but its own surface was only exercised incidentally by other suites — line coverage sat at 49%, leaving the secret sub-surface and the pg_llm_batch adapter untested. Add a focused `tests/test_kv_config.py` (13 tests, dependency-free — small fakes stand in for the pg_llm_batch config/secret stores) pinning the full contract: - InMemoryConfigStore: seed loading, get/set roundtrip + default, get_category returns a non-aliasing copy, show_config sorted ordering, and the set_secret/get_secret/require_secret surface (incl. secrets staying out of show_config and require_secret raising KeyError when absent). - PostgresConfigStoreAdapter: get/set delegation, and get_secret/require_secret behavior with and without a backing secret store (default vs. KeyError, and swallowing a backing-store error to the default). - get_config_store: the no-DSN in-memory selection path, seeded and unseeded. kv_config.py line coverage 49% -> 100% (the pg_llm_batch-present branch remains `# pragma: no cover`, as before). Full suite: 313 passed (was 300). Test-only; no production behavior changes.

…-> 100%) Completes the KV credential-seam coverage started in the kv_config test: the non-DB surface of credentials.py was uncovered — PostgresCredentialBackend argument validation, from_env bootstrap-transport reads, and the _select_backend postgres branch (the live pgcrypto/psycopg methods stay # pragma: no cover). Add tests/test_credentials_backend.py (8 tests, no Postgres needed) pinning the "KV, not env" bootstrap boundary: - PostgresCredentialBackend raises NotConfigured on an empty DSN or passphrase, and stores both (lazy schema) when valid. - from_env builds from exactly the two bootstrap env vars, and fails loudly when the DSN is unset (no silent empty backend). - _select_backend: memory default (case-insensitive), the postgres branch routes through from_env, and an unknown selector raises. credentials.py 83% -> 100%; combined with kv_config.py the KV seam is now 100%. Full suite 321 passed (was 313). Test-only; no production behavior changes.

…% -> 100%) The cost hub's token-accounting seam was 74% covered. Add tests/test_token_counting.py (5 tests, dependency-free — a fake stands in for pg_llm_batch.TokenCounter): the heuristic counter's empty/whitespace-only zero path and word/punctuation monotonicity; PgTiktokenAdapter count_text/count_messages delegation (incl. the non-dict message -> "" branch); and build_token_counter's no-DSN heuristic selection (the pg_llm_batch import path stays # pragma: no cover). token_counting.py 74% -> 100%. Full suite 326 passed (was 300). Test-only. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01T47gHdkeM8H2Mpu4VwZT3c

…> 100%) batch_routing is the cost hub's sync-vs-batch routing/execution surface; its embeddings path was undercovered. Add tests/test_batch_routing_embeddings.py (9 tests, no network / no pg-llm-batch install — a fake async client + fake assembler stand in): - LocalEmbeddingBatchBackend submit/poll/retrieve incl. the dependency-free token-count fallback (no token_counter) - PgLlmBatchEmbeddingBackend submit/poll/retrieve against a fake BatchAPIClient (both assembler and memory:// payload paths), result ordering + usage mapping, and empty-on-download-failure - helpers: heuristic_embedding (dimension + positive-guard), _extract_embedding (parse/defaults), _extract_answer (empty choices), cheapest_upstream (empty candidates -> None), EmbeddingBatchRequest.to_jsonl_line + build_embeddings_jsonl_body batch_routing.py 81% -> 100%. Test-only; no production change. Verified: 9 passed; full suite green. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01T47gHdkeM8H2Mpu4VwZT3c

Add targeted tests for previously-uncovered defensive/edge paths in the cost-hub router, all reachable and behavior-pinning: - _provider_from_base_url: mock scheme, real host extraction, empty input, and a malformed URL that must fall through the guarded parse to "" (never raise). - _positive_int: valid parse, ValueError/TypeError fallbacks, non-positive -> default. - _weighted_average_embedding: empty parts, all-empty-vector parts, and the weighted mean. - poll_batch / retrieve_batch / embeddings_batch_document: KeyError on an unknown job id. - _split_embedding_input / _force_token_safe_chunks: empty input, over-max_chars fixed-width split, and the token-dense single-unit midpoint-recursion fallback. - _count_embedding_tokens: tolerates a failing token counter (word-count fallback) and coerces a non-positive count on non-empty text to 1. cost_router.py coverage 89% -> 96% (full suite 341 passed). Tests only; no production behavior changes. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01T47gHdkeM8H2Mpu4VwZT3c

Pull request overview

OpenCode cannot approve yet because required coverage evidence did not pass.

Review outcome

1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence

Problem: The required coverage-evidence job result was failure, so OpenCode cannot establish approval sufficiency for this head.
Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.
Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports success with required evidence or explicit no-source not-applicable evidence.
Regression test: Keep the approval branch checking needs.coverage-evidence.result == success before posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present.
Result: REQUEST_CHANGES

Close the remaining cost_router.py branches to meet the org's 100% coverage standard: - _served_provider_model: the fallback path when the trace names an agent the orchestrator cannot resolve (lookup raises -> "unknown", fallback_model). - embeddings_batch_document: the pending return while the backend poll is not yet complete; the count_text token fallback when an item reports non-positive prompt_tokens and its request carries a zero token_count; and the empty-source branch when an input receives no returned embedding item. - _weighted_average_embedding: mark the total_weight<=0 guard `# pragma: no cover` — it is unreachable (each summand is max(1, ...) over a guaranteed-non-empty parts list), documented inline. Tests added drive a fake embeddings backend (pending / complete-with-gaps) via the public submit/document surface. Full suite: 344 passed; cost_router.py 100%.

Add 13 focused tests closing the remaining cost_ledger.py branches to meet the org's 100% coverage standard, all with real tests (no pragmas): - InMemoryUsageTelemetrySink event-list trim past max_events. - _emit_usage_event best-effort swallow when the sink raises. - NonBlockingLedgerStore: zero-queue-size guard, queue.Full drop path (+dropped telemetry), query delegation, flush timeout, worker success-path mark/emit. - InMemoryLedgerStore.__len__. - SQL ledger store time-window WHERE-clause builder (start/end params). - CostLedger: non-blocking store wrapping via flag; attribution passed as an AttributionDimensions instance; inline append failure marks health + emits an export_error event; flush no-op when the store has no flush(). Deterministic threading via Event-synchronized backends (no sleeps). Full suite: 357 passed; cost_ledger.py 100%.

Status at head 2f9a4e4: every required check is green — opencode-review ✅, noema-review ✅, coverage-evidence ✅ (the earlier atheris/coverage-image deadlock is cleared), strix ✅, coverage-source-tree ✅, full unit/contract suite ✅, trivy-fs/osv-scan/dependency-review/CodeQL/Scorecard ✅, Semgrep OSS ✅.

The only remaining red is Semgrep (multi-language SAST), and it is the pre-existing base-branch finding set in cost_ledger.py / orchestrator.py — this PR adds only tests/ files (kv_config, credentials, token_counting, batch_routing, cost_router, cost_ledger, all → 100% coverage) and introduces zero SAST findings of its own.

That base finding set is remediated by the open PRs #74 / #75 / #78 / #79 (none merged yet). This PR is not the right place to also fix it — a duplicate nosemgrep/source change here would collide with those and risk weakening the gate. As soon as one of those base-Semgrep remediations merges, this PR's Semgrep re-runs green against the updated base and it is ready to merge (I'll refresh the branch onto main at that point).

Closing as superseded by the combined coverage path in #75 and #79. #75 carries focused KV/config/token/batch coverage plus the two production bug fixes surfaced by that work; #79 carries the repository-wide 100% line/docstring gates and the remaining credential, router, ledger, and orchestrator branch tests. Merging this older overlapping test branch separately would duplicate test cases, reintroduce conflicts in the same files, and delay the canonical bug-fix-first sequence.
