feat/040-inventory-core (#43)
Summary
Implements Inventory Core (Spec 040): a tenant-scoped, mutable “last observed” inventory catalog + sync run logging, with deterministic selection hashing and safe derived “missing” semantics.
This establishes the foundation for Inventory UI (041), Dependencies Graph (042), Compare/Promotion (043), and Drift (044).
What’s included
• DB schema
• inventory_items (unique: tenant_id + policy_type + external_id; indexes; last_seen_at, last_seen_run_id)
• inventory_sync_runs (tenant_id, selection_hash/payload, status, started/finished, counts, error_codes, correlation_id)
• Selection hashing
• Deterministic selection_hash via canonical JSON (sorted keys + sorted arrays) + sha256
• Sync semantics
• Idempotent upsert (no duplicates)
• Updates last_seen_* when observed
• Enforces tenant scoping for all reads/writes
• Guardrail: inventory sync does not create snapshots/backups
• Missing semantics (derived)
• “missing” computed relative to latest completed run for same (tenant_id, selection_hash)
• Low confidence when latest run is partial/failed or had_errors=true
• Selection isolation (runs for other selections don’t affect missing)
• deleted is reserved (not produced here)
• Safety
• meta_jsonb whitelist enforced (unknown keys dropped; never fail sync)
• Safe error persistence (no bearer tokens / secrets)
• Locking to prevent overlapping runs for same tenant+selection
• Concurrency limiter (global + per-tenant) and throttling resilience (429/503 backoff + jitter)
Tests
Added Pest coverage for:
• selection_hash determinism (array order invariant)
• upsert idempotency + last_seen updates
• missing derived semantics + selection isolation
• low confidence missing on partial/had_errors
• meta whitelist drop (no exception)
• lock prevents overlapping runs
• no snapshots/backups side effects
• safe error persistence (no bearer tokens)
Non-goals
• Inventory UI pages/resources (Spec 041)
• Dependency graph hydration (Spec 042)
• Cross-tenant compare/promotion flows (Spec 043)
• Drift analysis dashboards (Spec 044)
Review focus
• Data model correctness + indexes/constraints
• Selection hash canonicalization (determinism)
• Missing semantics (latest completed run + confidence rule)
• Guardrails (no snapshot/backups side effects)
• Safety: error_code taxonomy + safe persistence/logging
