Summary

The Settings class has context_tier_hot_ttl_hours and context_tier_warm_ttl_hours fields but is missing the corresponding context_tier_cold_ttl_days field. The spec-required CLEVERAGENTS_CTX_COLD_DAYS environment variable is registered in ConfigService but has no corresponding Settings field, so ContextTierService cannot read the cold-tier retention policy from configuration.

Expected Behavior (per spec)

From docs/specification.md line 30776:

| `context.tiers.cold.retention-days` | integer | `90` | `CLEVERAGENTS_CTX_COLD_DAYS` | Number of days cold-tier context entries are retained before archival/expiry. |

The Settings class should have:

context_tier_cold_ttl_days: int = Field(
    default=90,
    ge=1,
    validation_alias=AliasChoices(
        "CLEVERAGENTS_CONTEXT_TIER_COLD_TTL_DAYS",
        "CLEVERAGENTS_CTX_COLD_DAYS",
    ),
    description="Days without access before cold fragment is archived/expired.",
)

Actual Behavior

In src/cleveragents/config/settings.py:

context_tier_hot_ttl_hours ✓ (with CLEVERAGENTS_CTX_HOT_HOURS alias)
context_tier_warm_ttl_hours ✓ (with CLEVERAGENTS_CTX_WARM_HOURS alias)
context_tier_cold_ttl_days ✗ MISSING

The ConfigService catalog at line 791 registers context.tiers.cold.retention-days with env_var="CLEVERAGENTS_CTX_COLD_DAYS", but this is never read by ContextTierService because there is no corresponding Settings field.

Code Location

src/cleveragents/config/settings.py — missing context_tier_cold_ttl_days field (compare with lines 350-368 for hot/warm TTL fields)
src/cleveragents/application/services/context_tiers.py — _cold_ttl_from_settings() helper function does not exist
src/cleveragents/application/services/config_service.py line 791 — context.tiers.cold.retention-days registered but not wired

Fix Required

Add context_tier_cold_ttl_days: int to Settings with CLEVERAGENTS_CTX_COLD_DAYS alias (default: 90)
Add _cold_ttl_from_settings() helper to context_tiers.py
Wire _cold_ttl into ContextTierService.__init__()

## Summary The `Settings` class has `context_tier_hot_ttl_hours` and `context_tier_warm_ttl_hours` fields but is **missing** the corresponding `context_tier_cold_ttl_days` field. The spec-required `CLEVERAGENTS_CTX_COLD_DAYS` environment variable is registered in `ConfigService` but has no corresponding `Settings` field, so `ContextTierService` cannot read the cold-tier retention policy from configuration. ## Expected Behavior (per spec) From `docs/specification.md` line 30776: ``` | `context.tiers.cold.retention-days` | integer | `90` | `CLEVERAGENTS_CTX_COLD_DAYS` | Number of days cold-tier context entries are retained before archival/expiry. | ``` The `Settings` class should have: ```python context_tier_cold_ttl_days: int = Field( default=90, ge=1, validation_alias=AliasChoices( "CLEVERAGENTS_CONTEXT_TIER_COLD_TTL_DAYS", "CLEVERAGENTS_CTX_COLD_DAYS", ), description="Days without access before cold fragment is archived/expired.", ) ``` ## Actual Behavior In `src/cleveragents/config/settings.py`: - `context_tier_hot_ttl_hours` ✓ (with `CLEVERAGENTS_CTX_HOT_HOURS` alias) - `context_tier_warm_ttl_hours` ✓ (with `CLEVERAGENTS_CTX_WARM_HOURS` alias) - `context_tier_cold_ttl_days` ✗ **MISSING** The `ConfigService` catalog at line 791 registers `context.tiers.cold.retention-days` with `env_var="CLEVERAGENTS_CTX_COLD_DAYS"`, but this is never read by `ContextTierService` because there is no corresponding `Settings` field. ## Code Location - `src/cleveragents/config/settings.py` — missing `context_tier_cold_ttl_days` field (compare with lines 350-368 for hot/warm TTL fields) - `src/cleveragents/application/services/context_tiers.py` — `_cold_ttl_from_settings()` helper function does not exist - `src/cleveragents/application/services/config_service.py` line 791 — `context.tiers.cold.retention-days` registered but not wired ## Fix Required 1.

Issue triaged by project owner:

State: Verified
Priority: Critical — The Settings class is missing the context_tier_cold_ttl_days field, meaning CLEVERAGENTS_CTX_COLD_DAYS env var is not wired to ContextTierService. Cold-tier TTL configuration is completely non-functional.
Milestone: v3.4.0 — ACMS v1 + Context Scaling is the v3.4.0 deliverable. Cold-tier TTL is a required configuration knob for the context tier system.
Story Points: 3 — M — Adding the field to Settings and wiring it through to ContextTierService is a targeted change, but requires careful testing of the full tier configuration path.
MoSCoW: Must Have — The spec requires all three tier TTL settings to be configurable. Missing one makes the tier system partially non-configurable.
Parent Epic: Needs linking to the ACMS/Context Tier epic under Legendary #377.

State: Verified
Priority: Critical — Settings class missing context_tier_cold_ttl_days field means the CLEVERAGENTS_CONTEXT_TIER_COLD_TTL_DAYS env var is silently ignored. Context tier configuration is a core ACMS feature. Missing settings fields cause silent misconfiguration.
Milestone: v3.5.0 — ACMS context tier management is a v3.5.0 deliverable.
Story Points: 5 — L size. Adding a missing settings field with env var binding, validation, and tests.
MoSCoW: Must Have — Settings fields that are documented in the spec but missing from the implementation are Must Have fixes. Silent env var ignoring is a correctness bug.
