 - **Automation Tracking Format**: All automation tracking issues now use a standardized

   declarations, enabling precise staleness detection.
+- Fixed ACMS indexing pipeline not wired into CLI — ContextTierService
+  started empty on every CLI invocation so LLM received zero file context
+  during plan execution. Added `context_tier_hydrator.py` that reads files
+  from linked project resources (via `git ls-files` or `os.walk`) and
+  stores them as `TieredFragment` objects in the tier service. Hydration
+  runs automatically before context assembly in `LLMExecuteActor.execute()`.
+  Respects max file size (256KB), total budget (10MB), binary file
+  exclusion, and `.git`/`node_modules`/`__pycache__` directory skipping.

+Feature: Context tier hydration from linked resources (#1028)
+  Verifies that ContextTierService is populated from project
+  resources before LLM context assembly.
+
+  Scenario: Hydrate tiers from git-checkout resource for ctx_hydrate
+    Given a temp git repo with 2 files for ctx_hydrate
+    And a ContextTierService instance for ctx_hydrate
+    When I hydrate tiers from the resource for ctx_hydrate
+    Then the tier service should have 2 fragments for ctx_hydrate
+
+  Scenario: Hydrate skips binary files for ctx_hydrate
+    Given a temp dir with 1 text and 1 binary file for ctx_hydrate
+    And a ContextTierService instance for ctx_hydrate
+    When I hydrate tiers from the resource for ctx_hydrate
+    Then the tier service should have 1 fragment for ctx_hydrate
+
+  Scenario: Hydrate skips files over size limit for ctx_hydrate
+    Given a temp dir with 1 large file for ctx_hydrate
+    And a ContextTierService instance for ctx_hydrate
+    When I hydrate tiers from the resource for ctx_hydrate
+    Then the tier service should have 0 fragments for ctx_hydrate
+
+  Scenario: Hydrate sets project_name on fragments for ctx_hydrate
+    Given a temp dir with 1 text file for ctx_hydrate
+    And a ContextTierService instance for ctx_hydrate
+    When I hydrate tiers from the resource for ctx_hydrate
+    Then each fragment project_name should be "local/test-project" for ctx_hydrate
+
+  Scenario: Hydrate sets resource_id on fragments for ctx_hydrate
+    Given a temp dir with 1 text file for ctx_hydrate
+    And a ContextTierService instance for ctx_hydrate
+    When I hydrate tiers from the resource for ctx_hydrate
+    Then each fragment resource_id should not be empty for ctx_hydrate
+
+  Scenario: Hydrate returns 0 for missing location for ctx_hydrate
+    Given a ContextTierService instance for ctx_hydrate
+    When I hydrate tiers from a missing location for ctx_hydrate
+    Then the hydration count should be 0 for ctx_hydrate
