Resolves #11846

Summary

Sub 10 of Epic #11831 — moves the 10 cross-daemon services out of ai/daemons/services/ (cleared by Subs 8 + 9) into thematic ai/services/{graph,ingestion}/ folders mirroring the existing ai/services/{github-workflow,gitlab-workflow,knowledge-base,memory-core,neural-link}/ buckets. The empty ai/daemons/services/ folder + test/playwright/unit/ai/daemons/services/ mirror are removed.

Evidence: L1 (61/61 moved-spec + 119/119 orchestrator + 130/130 touched-consumer; 2011 pass / 19 pre-existing flakes on full unit) → L1 required for substrate refactor (pure structural moves + mechanical import rewires; no behavioral change).

Source moves (10)

To ai/services/graph/ (6):

• GapInferenceEngine.mjs, GoldenPathSynthesizer.mjs, GraphMaintenanceService.mjs
• LazyEdgeDrainer.mjs, SemanticGraphExtractor.mjs, TopologyInferenceEngine.mjs

To ai/services/ingestion/ (4):

• ConceptDiscoveryService.mjs, ConceptIngestor.mjs, IssueIngestor.mjs, MemorySessionIngestor.mjs

Test moves (7)

Mirror source structure: 3 → test/playwright/unit/ai/services/graph/, 4 → test/playwright/unit/ai/services/ingestion/. (3 of the moved services have no spec files currently — GapInferenceEngine, GraphMaintenanceService, TopologyInferenceEngine.)

Folder cleanup

• ai/daemons/services/ removed (now empty post-Subs 8+9+10)
• test/playwright/unit/ai/daemons/services/ removed

Consumer updates

Depth preserved (both old ai/daemons/services/X and new ai/services/{graph,ingestion}/X are 2-deep under ai/). Most consumer imports needed only substring substitution daemons/services/X.mjs → services/{folder}/X.mjs. Manual fixes for relative-path consumers whose strings don't contain the literal daemons/ segment:

• Orchestrator.mjs:32 — '../services/GoldenPathSynthesizer.mjs' (resolves to old ai/daemons/services/) → '../../services/graph/...'
• DreamService.mjs:14-23 — 9× '../../services/X.mjs' pattern → '../../../services/{folder}/...'

22 consumer files updated total (covers ai/services/, ai/services/memory-core/, ai/services/github-workflow/, ai/scripts/priorityBackfill.mjs, ai/mcp/server/memory-core/config.template.mjs, buildScripts/ai/runSandman.mjs, plus 15 spec files).

V-B-A discipline (#11845 lesson)

Sub 9's missed relative-path patterns (SummarizationCoordinator's relative bridge-queries import) prompted me to follow substring-sweep with a second-stage grep for proximity-relative patterns:

grep -rnE "from\s+['\"]\\.\\.([./]+)services/(Gap|Golden|Graph|Lazy|Semantic|Topology|Concept|Issue|MemorySession)" ai/daemons/orchestrator/

That caught the 10 stale Orchestrator + DreamService refs that substring substitution missed. Same dual-sweep applied for dynamic await import() — none found.

Test Evidence

• Moved-spec subsuite (test/playwright/unit/ai/services/{graph,ingestion}/): 61/61 pass (1.9s)
• Orchestrator suite: 119/119 pass (6.5s) — DreamService spec needed individual rerun due to parallel-worker Chroma contention flake; passes deterministically when run alone
• Touched consumer specs (GraphService + MailboxService + MemoryService.Frontier + WakeSubscription + SyncService.Stage2): 130/130 pass (1.5s)
• Full unit suite: 2011 pass / 19 fail / 2 skip / 10 did-not-run. All 19 failures pre-existing (mcp/Authorization, scripts/checkAllAgentIdle×2, scripts/checkSunsetted×5, services/memory-core/{QueryReRanker, SessionSummarization, TextEmbeddingService.retry}, grid/{LockedColumns×2, Pooling×3, Teleportation×2}, vdom/table/Container); verified ZERO references to moved files via grep.

Post-Merge Validation

• Operator restarts orchestrator → DreamService boots, all 9 services resolve from ai/services/{graph,ingestion}/
• Operator confirms npm run ai:dream (if exposed) + scheduled DREAM_TASK cycle runs cleanly
• Integration suite passes on dev post-merge

Deltas from ticket

None — implementation matches #11846 ACs verbatim. (Did NOT include any cosmetic JSDoc @class Neo.ai.daemons.services.X namespace re-anchoring — that's a follow-up cleanup, separate scope; the file moves alone are functionally complete.)

Depends on

• Sub 8 #11844 — merged ✓
• Sub 9 #11845 — merged ✓ (cleared ai/daemons/services/ of orchestrator-private + sub-daemon-specific files; this PR moves the remainder)

Unblocks

• Sub 11 #11847 (ai/scripts/ thematic split)
• Sub 12 #11848 (buildScripts/ai/ collapse)
