docs: add test plans for subgraph denial and reward conditions

Draft test plans covering issuance upgrade behavior changes beyond REO:
- SubgraphDenialTestPlan: 6 cycles, 18 tests for deny/undeny lifecycle,
  accumulator freeze, allocation-level deferral, reward recovery
- RewardsConditionsTestPlan: 7 cycles, 26 tests for reclaim system,
  below-minimum signal, zero allocated tokens, POI presentation paths,
  allocation resize/close, observability

Updated README with dependency tree and coverage summaries.
Added 44 new tests to NotionTracker.csv.

-Comprehensive test plans for validating The Graph Network after the Rewards Eligibility Oracle (REO) upgrade. Two-layer approach: baseline indexer operations (upgrade-agnostic) plus REO-specific eligibility, oracle, and rewards tests.
+Comprehensive test plans for validating The Graph Network after the issuance upgrade. Three-layer approach: baseline indexer operations (upgrade-agnostic), REO-specific eligibility and oracle tests, and reward condition tests covering denial, reclaim, signal, POI paths, and allocation lifecycle changes.
 
 ## Quick Start
 
 1. **Indexers start here** → Follow [IndexerTestGuide.md](IndexerTestGuide.md)
 2. **Detailed baseline reference** → [BaselineTestPlan.md](BaselineTestPlan.md)
-3. **Detailed REO reference** → [ReoTestPlan.md](ReoTestPlan.md)
+3. **REO eligibility tests** → [ReoTestPlan.md](ReoTestPlan.md)
+4. **Subgraph denial tests** → [SubgraphDenialTestPlan.md](SubgraphDenialTestPlan.md)
+5. **Reward conditions tests** → [RewardsConditionsTestPlan.md](RewardsConditionsTestPlan.md)
 
 ## Reading Order
 
 1. **[BaselineTestPlan.md](BaselineTestPlan.md)** -- Upgrade-agnostic indexer operations (run first)
 2. **[ReoTestPlan.md](ReoTestPlan.md)** -- REO-specific eligibility, oracle, and rewards tests (run after baseline passes)
-3. **[IndexerTestGuide.md](IndexerTestGuide.md)** -- Condensed guide for indexers running eligibility tests (subset of ReoTestPlan)
+3. **[RewardsConditionsTestPlan.md](RewardsConditionsTestPlan.md)** -- Reclaim system, signal conditions, POI paths, allocation lifecycle (run after baseline passes; Cycle 1 configures reclaim addresses needed by other plans)
+4. **[SubgraphDenialTestPlan.md](SubgraphDenialTestPlan.md)** -- Subgraph denial two-level handling, accumulator freeze, deferral, deny/undeny lifecycle (run after reclaim setup)
+5. **[IndexerTestGuide.md](IndexerTestGuide.md)** -- Condensed guide for indexers running eligibility tests (subset of ReoTestPlan)
