🚀 Major Changes

Streaming as Default Output

• Legacy polling code fully removed; streaming is now the default output path internally and via ACP
• Streaming responses working end-to-end via ACP and UI with e2e-ui tests
• aoctl binary streaming logic fixed for agent sessions

ACP Protocol Implementation

• Full ACP standard implementation in the ACP endpoint and aoctl binary
• aoctl acp configure and aoctl acp serve commands for Zed editor integration
• Federated OIDC support for admin endpoint access via aoctl

Hindsight Integration for Persistent Agent Intelligence

• Added hindsight mechanism enabling agents to retain and learn from previous interactions
• Agents become progressively smarter over longer runs by recalling past conversations and tool calls
• Integrated with context management via ContextCompactionRatio and compactionTarget() to retain relevant history while preventing memory bloat
• LLM responses are processed through hindsight during streaming to build persistent context
• Enables agents to build on previous work rather than repeating steps, improving decision-making in extended sessions

🐛 Bug Fixes

• Context compaction: Fixed live buffer growing unboundedly during tool-call loops; added capLiveBufferDuringToolLoop() to compact at proactive threshold
• Token stream cap: Raised Redis token/trace-event stream cap from 10,000 to 100,000 entries to prevent front-trimming on replay for long runs
• Tool result truncation: Stopped silently truncating large tool results; context-window-aware MaxToolResultTokens default (~10% of model context window, 8k-64k range)
• Warm pod reuse: Fixed warm pods not returned to idle after completion; pods now reused across chat turns instead of spawning fresh each turn
• Conversation persistence: Checkpoint now runs on terminal text turn/[DONE] so short chats (< CheckpointEvery) are persisted
• MCP auth: Fixed warm-pool router config omitting MCP auth resolution for remote HTTP MCP servers (e.g., Slack → -32001 missing_token)
• Nil pointer: Fixed nil-pointer panic in MCP HTTP client on transport errors
• Swallowed errors: Fixed ArchiveRun silently swallowing PostgreSQL errors
• ListenAndServe: Fixed ignored ListenAndServe error
• Streaming tool dispatch: Fixed streaming tool calls dispatching on len>0 not finishReason; normalized [DONE] sentinel handling
• UI multi-namespace: Fixed UI tenant scoping to list resources across all authorized namespaces (not just tenant.Namespace)

⚡ Performance & Reliability

• Async context compaction: Implemented asynchronous context compaction with incremental token tracking (liveBufferTokens cached counter, spawnCompaction background goroutine)
• Proactive truncation: Configurable compaction target (default 50%, settable to 10%) decoupled from 80% safety ceiling
• Efficient summaries: Compaction summaries reduced from ~300-500 tokens to ~100-200 tokens
• Loop guards: Conservative defaults added (MaxRepeatedToolCalls=50, MaxConsecutiveNoopTurns=15) to halt stuck loops instead of spinning
• Stream cap: Token stream cap increased 10x to survive very long runs

🔧 Developer Experience

• CI fixes: Fixed release-drafter and enforce-pr-to-main workflows; all GitHub MCP tools enabled for programming-agent demo
• Lint: Fixed all 119 golangci-lint issues including 3 real bugs; go vet ./... clean
• Branch protection: Added branch naming convention check + comprehensive branch protection workflow (enforce PR-only merges to main)
• Toolchain: Added mise toolchain config (.mise.toml) pinning Go 1.25.3, Node 20, Make 4.4, helm 3.14; removed devcontainers
• Documentation: Added KNOWN_ISSUES.md tracker, context management guide, architecture diagram updates
• Dead code removal: Removed ~310 lines of unused router safeguard functions, write-only state fields, orphaned aoctl helpers
• Deprecated APIs: Replaced result.Requeue, NewSimpleClientset with modern equivalents

📦 Infrastructure

• Container images: Updated all references from ghcr.io/agentorca/agent-orca to ghcr.io/heddles/agent-orca
• PostgreSQL: Added PostgreSQL for proper RBAC and historical data aggregation
• Model providers: Added query/doc prompts to ModelProvider CRDs for RAG efficiency
• OAuth MCP: Generic OAuth credential manager for OAuth-only MCP servers (Slack, etc.)
• Metrics: Fixed metrics endpoint exposure; added ServiceMonitors/PodMonitors

🔒 Security

• Branch protection: Enforced PR-only merges to main with required checks
• Privileged pods: Fail-closed gate for privileged pod overrides (namespace label + guardrail policy ref required)
• Secret scanning: Proper RBAC and secret management for OAuth tokens
