## Summary TDD expected-fail tests proving bug #821 exists: `ContextTierService` has data models for hot/warm/cold tiers but **no runtime logic** for automatic promotion, demotion, or eviction. - **Promotion on access**: Accessing a cold-tier fragment repeatedly via `get()` does NOT auto-promote it — `get()` updates `access_count`/`last_accessed` but never calls `promote()` - **Demotion on staleness**: No staleness enforcement method exists — tried `enforce_staleness()`, `apply_tier_policy()`, `tick()`, etc. — none are implemented - **Eviction on budget overflow**: `store()` does NOT enforce `TierBudget.max_tokens_hot` — the hot tier grows without bound ### Files Added | File | Purpose | |------|---------| | `features/tdd_context_tier_runtime.feature` | 3 Behave scenarios tagged `@tdd_expected_fail @tdd_bug @tdd_bug_821 @mock_only` | | `features/steps/tdd_context_tier_runtime_steps.py` | Type-annotated step definitions exercising real `ContextTierService` | | `robot/tdd_context_tier_runtime.robot` | 3 Robot Framework integration tests tagged `tdd_expected_fail` | | `robot/helper_tdd_context_tier_runtime.py` | Helper script for Robot tests with 3 subcommands | ### Verification - `nox -s lint` — passed - `nox -s typecheck` — passed (0 errors) - `nox -s unit_tests -- features/tdd_context_tier_runtime.feature` — **3 scenarios passed** (all assertions fail as expected, `@tdd_expected_fail` inverts to CI pass) ISSUES CLOSED: #840 Reviewed-on: #1058 Co-authored-by: Brent Edwards <brent.edwards@cleverthis.com> Co-committed-by: Brent Edwards <brent.edwards@cleverthis.com>

Documentation TDD Bug #821 — context tier service has data models but no runtime logic
|
|
... for promotion, demotion, or eviction. Integration smoke tests verifying
|
|
... that ContextTierService automatically promotes fragments on repeated access,
|
|
... demotes stale fragments, and evicts fragments when the hot tier budget
|
|
... overflows. Currently the service has manual promote()/demote()/evict_lru()
|
|
... methods but no automatic runtime behaviour wired into get() or store().
|
|
... Tests are tagged tdd_expected_fail so CI passes via result inversion.
