feat: Agent Dreaming Mode — idle background reflection loop (#1019)

- Add src/timmy/dreaming.py with DreamingEngine: rule synthesis from
  session logs during idle periods with configurable wake/sleep thresholds
- Add src/dashboard/routes/dreaming.py with REST endpoints for
  dreaming status, history, and manual trigger
- Add dreaming_status.html partial template for HTMX polling
- Wire dreaming_router into dashboard app
- Add dreaming CSS styles to mission-control.css
- Add dreaming_enabled/dreaming_idle_threshold_s config settings

+## One-Agent-Per-Issue Convention
+
+**An issue must only be worked by one agent at a time.** Duplicate branches from
+multiple agents on the same issue cause merge conflicts, redundant code, and wasted compute.
+
+### Labels
+
+When an agent picks up an issue, add the corresponding label:
+
+| Label | Meaning |
+|-------|---------|
+| `assigned-claude` | Claude is actively working this issue |
+| `assigned-gemini` | Gemini is actively working this issue |
+| `assigned-kimi` | Kimi is actively working this issue |
+| `assigned-manus` | Manus is actively working this issue |
+
+### Rules
+
+1. **Before starting an issue**, check that none of the `assigned-*` labels are present.
+   If one is, skip the issue — another agent owns it.
+2. **When you start**, add the label matching your agent (e.g. `assigned-claude`).
+3. **When your PR is merged or closed**, remove the label (or it auto-clears when
+   the branch is deleted — see Auto-Delete below).
+4. **Never assign the same issue to two agents simultaneously.**
+
+### Auto-Delete Merged Branches
+
+`default_delete_branch_after_merge` is **enabled** on this repo. Branches are
+automatically deleted after a PR merges — no manual cleanup needed and no stale
+`claude/*`, `gemini/*`, or `kimi/*` branches accumulate.
+
+If you discover stale merged branches, they can be pruned with:
+```bash
+git fetch --prune
+```
+
+---
+
 ## Merge Policy (PR-Only)
 
 **Gitea branch protection is active on `main`.** This is not a suggestion.

+| Branch A | Branch B | Action |
+|----------|----------|--------|
+| `feature/internal-monologue` | `feature/issue-1005` | Exact duplicate — delete one |
+| `claude/issue-1005` | (above) | Merge-from-main only — delete |
+
+#### Unmerged Work With No Open PR (HIGH PRIORITY)
+| Branch | Content | Issues |
+|--------|---------|--------|
+| `claude/issue-987` | Content moderation pipeline, Llama Guard integration | No open PR — potentially lost |
+| `claude/issue-1011` | Automated skill discovery system | No open PR — potentially lost |

+
+#### PRs Closed Without Merge (Issues Still Open)
+| PR | Title | Issue Status |
+|----|-------|-------------|

+
+#### Workflow Observations
+- `loop-cycle` bot auto-creates micro-fix PRs at high frequency (PR numbers climbing past 1209 rapidly)
+- Many `gemini/*` branches represent incomplete agent sessions, not full feature work
+- Issues get reassigned across agents causing duplicate branch proliferation

+### 11. hermes/hermes-config, rockachopa/hermes-config, Timmy_Foundation/.profile
+
+**Status:** Dormant config repos. No action needed.
+
+---
+
+## Cross-Repo Patterns & Inefficiencies
+
+### Duplicate Work
+1. **Timmy spring/wobble physics** built independently in both `replit/timmy-tower` and `replit/token-gated-economy`
+2. **Nostr identity logic** fragmented across 3 repos with no shared library
+3. **`feature/internal-monologue` = `feature/issue-1005`** in Timmy-time-dashboard — identical SHA, exact duplicate
+
+### Agent Workflow Issues
+- Same issue assigned to both `gemini/*` and `claude/*` agents creates duplicate branches
+- Agent salvage commits are checkpoint-only — not complete work, but clutter the branch list
+- Gemini `feature/*` branches created on 2026-03-22 with no PRs filed — likely a failed agent session that created branches but didn't complete the loop
+
+### Review Bottlenecks
+| Repo | Waiting PRs | Notes |
+|------|-------------|-------|
+| rockachopa/the-matrix | 8 | Batch-created, need human review |
+| replit/timmy-tower | 2 | Database schema and UI work |
+| rockachopa/hermes-agent | 1 | AutoLoRA v1 — high value |
+| Timmy_Foundation/the-nexus | 1 | Contributor audit |
+
+---
+
+## Recommended Actions
+
+### Immediate (This Sprint)
+1. **Review & merge** PR#33 in `hermes-agent` (AutoLoRA v1)
+2. **Review** 8 open PRs in `the-matrix` before merging as a batch
+3. **Rescue** unmerged work in `claude/issue-987`, `claude/issue-1011`, `gemini/issue-976` — file new PRs or close branches
+4. **Delete duplicate** `feature/internal-monologue` / `feature/issue-1005` branches
+
+### Cleanup Sprint
+5. **Delete ~65 stale branches** across all repos (itemized above)
+6. **Investigate** the 5 closed-without-merge PRs in Timmy-time-dashboard for p0-critical issues
+7. **Archive** `hermes/timmy-time-app` if no longer needed
+8. **Clarify** ownership of `google/maintenance-tasks` and `google/wizard-council-automation`
+
+### Process Improvements
+9. **Enforce one-agent-per-issue** policy to prevent duplicate `claude/*` / `gemini/*` branches
+10. **Add branch protection** requiring PR before merge on `main` for all repos
+11. **Set a branch retention policy** — auto-delete merged branches (GitHub/Gitea supports this)
+12. **Share common libraries** for Nostr identity and animation physics across repos

+# ADR-024: Canonical Nostr Identity Location
+
+**Status:** Accepted
+**Date:** 2026-03-23
+**Issue:** #1223
+**Refs:** #1210 (duplicate-work audit), ROADMAP.md Phase 2
+
+---
+
+## Context
+
+Nostr identity logic has been independently implemented in at least three
+repos (`replit/timmy-tower`, `replit/token-gated-economy`,
+`rockachopa/Timmy-time-dashboard`), each building keypair generation, event
+publishing, and NIP-07 browser-extension auth in isolation.
+
+This duplication causes:
+
+- Bug fixes applied in one repo but silently missed in others.
+- Diverging implementations of the same NIPs (NIP-01, NIP-07, NIP-44).
+- Agent time wasted re-implementing logic that already exists.
+
+ROADMAP.md Phase 2 already names `timmy-nostr` as the planned home for Nostr
+infrastructure. This ADR makes that decision explicit and prescribes how
+other repos consume it.
+
+---
+
+## Decision
+
+**The canonical home for all Nostr identity logic is `rockachopa/timmy-nostr`.**
+
+All other repos (`Timmy-time-dashboard`, `timmy-tower`,
+`token-gated-economy`) become consumers, not implementers, of Nostr identity
+primitives.
+
+### What lives in `timmy-nostr`
+
+| Module | Responsibility |
+|--------|---------------|
+| `nostr_id/keypair.py` | Keypair generation, nsec/npub encoding, encrypted storage |
+| `nostr_id/identity.py` | Agent identity lifecycle (NIP-01 kind:0 profile events) |
+| `nostr_id/auth.py` | NIP-07 browser-extension signer; NIP-42 relay auth |
+| `nostr_id/event.py` | Event construction, signing, serialisation (NIP-01) |
+| `nostr_id/crypto.py` | NIP-44 encryption (XChaCha20-Poly1305 v2) |
+| `nostr_id/nip05.py` | DNS-based identifier verification |
+| `nostr_id/relay.py` | WebSocket relay client (publish / subscribe) |
+
+### What does NOT live in `timmy-nostr`
+
+- Business logic that combines Nostr with application-specific concepts
+  (e.g. "publish a task-completion event" lives in the application layer
+  that calls `timmy-nostr`).
+- Reputation scoring algorithms (depends on application policy).
+- Dashboard UI components.
+
+---
+
+## How Other Repos Reference `timmy-nostr`
+
+### Python repos (`Timmy-time-dashboard`, `timmy-tower`)
+
+Add to `pyproject.toml` dependencies:
+
+```toml
+[tool.poetry.dependencies]
+timmy-nostr = {git = "https://gitea.hermes.local/rockachopa/timmy-nostr.git", tag = "v0.1.0"}
+```
+
+Import pattern:
+
+```python
+from nostr_id.keypair import generate_keypair, load_keypair
+from nostr_id.event import build_event, sign_event
+from nostr_id.relay import NostrRelayClient
+```
+
+### JavaScript/TypeScript repos (`token-gated-economy` frontend)
+
+Add to `package.json` (once published or via local path):
+
+```json
+"dependencies": {
+  "timmy-nostr": "rockachopa/timmy-nostr#v0.1.0"
+}
+```
+
+Import pattern:
+
+```typescript
+import { generateKeypair, signEvent } from 'timmy-nostr';
+```
+
+Until `timmy-nostr` publishes a JS package, use NIP-07 browser extension
+directly and delegate all key-management to the browser signer — never
+re-implement crypto in JS without the shared library.
+
+---
+
+## Migration Plan
+
+Existing duplicated code should be migrated in this order:
+
+1. **Keypair generation** — highest duplication, clearest interface.
+2. **NIP-01 event construction/signing** — used by all three repos.
+3. **NIP-07 browser auth** — currently in `timmy-tower` and `token-gated-economy`.
+4. **NIP-44 encryption** — lowest priority, least duplicated.
+
+Each step: implement in `timmy-nostr` → cut over one repo → delete the
+duplicate → repeat.
+
+---
+
+## Interface Contract
+
+`timmy-nostr` must expose a stable public API:
+
+```python
+# Keypair
+keypair = generate_keypair()           # -> NostrKeypair(nsec, npub, privkey_bytes, pubkey_bytes)
+keypair = load_keypair(encrypted_nsec, secret_key)
+
+# Events
+event = build_event(kind=0, content=profile_json, keypair=keypair)
+event = sign_event(event, keypair)     # attaches .id and .sig
+
+# Relay
+async with NostrRelayClient(url) as relay:
+    await relay.publish(event)
+    async for msg in relay.subscribe(filters):
+        ...
+```
+
+Breaking changes to this interface require a semver major bump and a
+migration note in `timmy-nostr`'s CHANGELOG.
+
+---
+
+## Consequences
+
+- **Positive:** Bug fixes in cryptographic or protocol code propagate to all
+  repos via a version bump.
+- **Positive:** New NIPs are implemented once and adopted everywhere.
+- **Negative:** Adds a cross-repo dependency; version pinning discipline
+  required.
+- **Negative:** `timmy-nostr` must be stood up and tagged before any
+  migration can begin.
+
+---
+
+## Action Items
+
+- [ ] Create `rockachopa/timmy-nostr` repo with the module structure above.
+- [ ] Implement keypair generation + NIP-01 signing as v0.1.0.
+- [ ] Replace `Timmy-time-dashboard` inline Nostr code (if any) with
+  `timmy-nostr` import once v0.1.0 is tagged.
+- [ ] Add `src/infrastructure/clients/nostr_client.py` as the thin
+  application-layer wrapper (see ROADMAP.md §2.6).
+- [ ] File issues in `timmy-tower` and `token-gated-economy` to migrate their
+  duplicate implementations.

+# Nexus — Scope & Acceptance Criteria
+
+**Issue:** #1208
+**Date:** 2026-03-23
+**Status:** Initial implementation complete; teaching/RL harness deferred
+
+---
+
+## Summary
+
+The **Nexus** is a persistent conversational space where Timmy lives with full
+access to his live memory. Unlike the main dashboard chat (which uses tools and
+has a transient feel), the Nexus is:
+
+- **Conversational only** — no tool approval flow; pure dialogue
+- **Memory-aware** — semantically relevant memories surface alongside each exchange
+- **Teachable** — the operator can inject facts directly into Timmy's live memory
+- **Persistent** — the session survives page refreshes; history accumulates over time
+- **Local** — always backed by Ollama; no cloud inference required
+
+This is the foundation for future LoRA fine-tuning, RL training harnesses, and
+eventually real-time self-improvement loops.
+
+---
+
+## Scope (v1 — this PR)
+
+| Area | Included | Deferred |
+|------|----------|----------|
+| Conversational UI | ✅ Chat panel with HTMX streaming | Streaming tokens |
+| Live memory sidebar | ✅ Semantic search on each turn | Auto-refresh on teach |
+| Teaching panel | ✅ Inject personal facts | Bulk import, LoRA trigger |
+| Session isolation | ✅ Dedicated `nexus` session ID | Per-operator sessions |
+| Nav integration | ✅ NEXUS link in INTEL dropdown | Mobile nav |
+| CSS/styling | ✅ Two-column responsive layout | Dark/light theme toggle |
+| Tests | ✅ 9 unit tests, all green | E2E with real Ollama |
+| LoRA / RL harness | ❌ deferred to future issue | |
+| Auto-falsework | ❌ deferred | |
+| Bannerlord interface | ❌ separate track | |
+
+---
+
+## Acceptance Criteria
+
+### AC-1: Nexus page loads
+- **Given** the dashboard is running
+- **When** I navigate to `/nexus`
+- **Then** I see a two-panel layout: conversation on the left, memory sidebar on the right
+- **And** the page title reads "// NEXUS"
+- **And** the page is accessible from the nav (INTEL → NEXUS)
+
+### AC-2: Conversation-only chat
+- **Given** I am on the Nexus page
+- **When** I type a message and submit
+- **Then** Timmy responds using the `nexus` session (isolated from dashboard history)
+- **And** no tool-approval cards appear — responses are pure text
+- **And** my message and Timmy's reply are appended to the chat log
+
+### AC-3: Memory context surfaces automatically
+- **Given** I send a message
+- **When** the response arrives
+- **Then** the "LIVE MEMORY CONTEXT" panel shows up to 4 semantically relevant memories
+- **And** each memory entry shows its type and content
+
+### AC-4: Teaching panel stores facts
+- **Given** I type a fact into the "TEACH TIMMY" input and submit
+- **When** the request completes
+- **Then** I see a green confirmation "✓ Taught: <fact>"
+- **And** the fact appears in the "KNOWN FACTS" list
+- **And** the fact is stored in Timmy's live memory (`store_personal_fact`)
+
+### AC-5: Empty / invalid input is rejected gracefully
+- **Given** I submit a blank message or fact
+- **Then** no request is made and the log is unchanged
+- **Given** I submit a message over 10 000 characters
+- **Then** an inline error is shown without crashing the server
+
+### AC-6: Conversation can be cleared
+- **Given** the Nexus has conversation history
+- **When** I click CLEAR and confirm
+- **Then** the chat log shows only a "cleared" confirmation
+- **And** the Agno session for `nexus` is reset
+
+### AC-7: Graceful degradation when Ollama is down
+- **Given** Ollama is unavailable
+- **When** I send a message
+- **Then** an error message is shown inline (not a 500 page)
+- **And** the app continues to function
+
+### AC-8: No regression on existing tests
+- **Given** the nexus route is registered
+- **When** `tox -e unit` runs
+- **Then** all 343+ existing tests remain green
+
+---
+
+## Future Work (separate issues)

+1. **LoRA trigger** — button in the teaching panel to queue a fine-tuning run
+   using the current Nexus conversation as training data
+2. **RL harness** — reward signal collection during conversation for RLHF
+3. **Auto-falsework pipeline** — scaffold harness generation from conversation
+4. **Bannerlord interface** — Nexus as the live-memory bridge for in-game Timmy
+5. **Streaming responses** — token-by-token display via WebSocket

+# Autoresearch H1 — M3 Max Baseline
+
+**Status:** Baseline established (Issue #905)
+**Hardware:** Apple M3 Max · 36 GB unified memory
+**Date:** 2026-03-23
+**Refs:** #905 · #904 (parent) · #881 (M3 Max compute) · #903 (MLX benchmark)
+
+---
+
+## Setup
+
+### Prerequisites
+
+```bash
+# Install MLX (Apple Silicon — definitively faster than llama.cpp per #903)
+pip install mlx mlx-lm
+
+# Install project deps
+tox -e dev  # or: pip install -e '.[dev]'
+```
+
+### Clone & prepare
+
+`prepare_experiment` in `src/timmy/autoresearch.py` handles the clone.
+On Apple Silicon it automatically sets `AUTORESEARCH_BACKEND=mlx` and
+`AUTORESEARCH_DATASET=tinystories`.
+
+```python
+from timmy.autoresearch import prepare_experiment
+status = prepare_experiment("data/experiments", dataset="tinystories", backend="auto")
+print(status)
+```
+
+Or via the dashboard: `POST /experiments/start` (requires `AUTORESEARCH_ENABLED=true`).
+
+### Configuration (`.env` / environment)
+
+```
+AUTORESEARCH_ENABLED=true
+AUTORESEARCH_DATASET=tinystories   # lower-entropy dataset, faster iteration on Mac
+AUTORESEARCH_BACKEND=auto          # resolves to "mlx" on Apple Silicon
+AUTORESEARCH_TIME_BUDGET=300       # 5-minute wall-clock budget per experiment
+AUTORESEARCH_MAX_ITERATIONS=100
+AUTORESEARCH_METRIC=val_bpb
+```
+
+### Why TinyStories?
+
+Karpathy's recommendation for resource-constrained hardware: lower entropy
+means the model can learn meaningful patterns in less time and with a smaller
+vocabulary, yielding cleaner val_bpb curves within the 5-minute budget.
+
+---
+
+## M3 Max Hardware Profile
+
+| Spec | Value |
+|------|-------|
+| Chip | Apple M3 Max |
+| CPU cores | 16 (12P + 4E) |
+| GPU cores | 40 |
+| Unified RAM | 36 GB |
+| Memory bandwidth | 400 GB/s |
+| MLX support | Yes (confirmed #903) |
+
+MLX utilises the unified memory architecture — model weights, activations, and
+training data all share the same physical pool, eliminating PCIe transfers.
+This gives M3 Max a significant throughput advantage over external GPU setups
+for models that fit in 36 GB.
+
+---
+
+## Community Reference Data
+
+| Hardware | Experiments | Succeeded | Failed | Outcome |
+|----------|-------------|-----------|--------|---------|
+| Mac Mini M4 | 35 | 7 | 28 | Model improved by simplifying |
+| Shopify (overnight) | ~50 | — | — | 19% quality gain; smaller beat 2× baseline |
+| SkyPilot (16× GPU, 8 h) | ~910 | — | — | 2.87% improvement |
+| Karpathy (H100, 2 days) | ~700 | 20+ | — | 11% training speedup |
+
+**Mac Mini M4 failure rate: 80% (26/35).** Failures are expected and by design —
+the 5-minute budget deliberately prunes slow experiments. The 20% success rate
+still yielded an improved model.
+
+---
+
+## Baseline Results (M3 Max)
+
+> Fill in after running: `timmy learn --target <module> --metric val_bpb --budget 5 --max-experiments 50`
+
+| Run | Date | Experiments | Succeeded | val_bpb (start) | val_bpb (end) | Δ |
+|-----|------|-------------|-----------|-----------------|---------------|---|
+| 1 | — | — | — | — | — | — |
+
+### Throughput estimate
+
+Based on the M3 Max hardware profile and Mac Mini M4 community data, expected
+throughput is **8–14 experiments/hour** with the 5-minute budget and TinyStories
+dataset. The M3 Max has ~30% higher GPU core count and identical memory
+bandwidth class vs M4, so performance should be broadly comparable.
+
+---
+
+## Apple Silicon Compatibility Notes
+
+### MLX path (recommended)
+
+- Install: `pip install mlx mlx-lm`
+- `AUTORESEARCH_BACKEND=auto` resolves to `mlx` on arm64 macOS
+- Pros: unified memory, no PCIe overhead, native Metal backend
+- Cons: MLX op coverage is a subset of PyTorch; some custom CUDA kernels won't port
+
+### llama.cpp path (fallback)
+
+- Use when MLX op support is insufficient
+- Set `AUTORESEARCH_BACKEND=cpu` to force CPU mode
+- Slower throughput but broader op compatibility
+
+### Known issues
+
+- `subprocess.TimeoutExpired` is the normal termination path — autoresearch
+  treats timeout as a completed-but-pruned experiment, not a failure
+- Large batch sizes may trigger OOM if other processes hold unified memory;
+  set `PYTORCH_MPS_HIGH_WATERMARK_RATIO=0.0` to disable the MPS high-watermark
+
+---
+
+## Next Steps (H2)
+
+See #904 Horizon 2 for the meta-autoresearch plan: expand experiment units from
+code changes → system configuration changes (prompts, tools, memory strategies).

+# Research Direction
+
+This file guides the `timmy learn` autoresearch loop.  Edit it to focus
+autonomous experiments on a specific goal.
+
+## Current Goal
+
+Improve unit test pass rate across the codebase by identifying and fixing
+fragile or failing tests.
+
+## Target Module
+
+(Set via `--target` when invoking `timmy learn`)
+
+## Success Metric
+
+unit_pass_rate — percentage of unit tests passing in `tox -e unit`.
+
+## Notes
+
+- Experiments run one at a time; each is time-boxed by `--budget`.
+- Improvements are committed automatically; regressions are reverted.
+- Use `--dry-run` to preview hypotheses without making changes.
