From: MASTER2 Unified Improvements
Subject: [PATCH] All fixes + domain knowledge restoration

Covers:
  Fix 1:  Axiom count derived from live DB
  Fix 2:  data/design.yml restored to OWN_PRIORITY
  Fix 3:  Pre-commit hook — ruby -c only, no kill
  Fix 4:  Commands.dispatch — single Result type
  Fix 5:  GroundedContext::safe_read logs errors
  Fix 6:  AgentFirewall :needs_review wired to gate
  Fix 7:  LLM#ask CQS — thread-local current_model
  Fix 8:  Scheduler UUID via SecureRandom
  Fix 9:  QualityGates — load-once, no mtime loop
  Fix 10: Persona system_prompt derived from fields
  Fix 11: Chamber::MODELS loads from models.yml
  Fix 12: master self always runs :deep
  Fix 13: Tautology test deleted; banner test has assertions
  Fix 14: run_phase1/2/3 renamed to meaningful names
  Fix 15: SKIP_DIRS single source in Paths
  New:    data/stack.yml — Ruby, Rails 8, zsh, OpenBSD
  New:    data/html_css.yml — HTML/CSS rules, forbidden, required
  New:    data/ui_ux_seo.yml — Nielsen, SEO, mobile patterns
  New:    data/typography.yml — Bringhurst, tokens, flat rules
  Patch:  data/personas.yml — remove inline system_prompt keys
  Patch:  data/system_prompt.yml — H: user prefs block, bias list
  Patch:  data/constitution.yml additions — sharp edges, bias names
  Patch:  lib/executor/grounded_context.rb — OWN_PRIORITY restored

+# Typography and Design System Rules
+# Domain knowledge from master.json/yml — 300+ iterations.
+# Philosophy hierarchy: Ando → Rams → Swiss → Bringhurst → Brutalism

+# ─── DESIGN PHILOSOPHY ─────────────────────────────────────────────────────
+philosophy:
+  primary:  "The best design is no design — remove until nothing left to remove (Rams)"
+  core:     "Design is mostly just typography. Everything else is distraction."
+  negative_space: "70% whitespace minimum. Absence is structure, not emptiness (Ando)."
+  brutalist: "Semantic HTML only. System fonts. Monochrome. Size creates hierarchy."
+  sources:
+    - "Tadao Ando — void, negative space, concrete, natural light"
+    - "Dieter Rams — 10 principles, less but better"
+    - "Josef Müller-Brockmann — mathematical grids, Swiss International Style"
+    - "Robert Bringhurst — The Elements of Typographic Style"
+    - "Jan Tschichold — asymmetric typography, functional design"

+# ─── FLAT AESTHETIC — ENFORCED, BLOCKING ───────────────────────────────────
+flat_aesthetic:
+  status:    "ENFORCED — violations are blocking"
+  forbidden:
+    - box-shadow
+    - text-shadow
+    - gradients          # background: linear-gradient(...) — forbidden
+    - border-radius      # decorative use — forbidden
+    - blur
+    - "3d transforms"
+    - background-image   # decorative
+  allowed:
+    - flat_colors
+    - typography
+    - whitespace
+    - pure_geometry
+    - "focus rings (required for WCAG)"
+  principle: "Geometry and typography create hierarchy. Never color or shadow."

+# ─── BRINGHURST SPECIFICS ──────────────────────────────────────────────────
+bringhurst:
+  measure:          "45–75ch (65ch ideal for body text)"
+  line_height:      "1.4–2.0 (1.6 for body)"
+  baseline_grid:    "8px (6pt for print)"
+  golden_ratio:     "1.618"
+  perfect_fifth:    "3:2"
+  scale_rule:       "use Perfect Fifth (3:2) or Golden Ratio (1.618) — not arbitrary sizes"
+  optical_margin:   "true — characters aligned to optical edge, not metric edge"
+  kerning:
+    body:    "0 — default"
+    caps:    "+0.05em"
+    display: "-0.02em"
+  numerals:  "old-style in body text (font-variant-numeric: oldstyle-nums)"
+  max_width: "680px — Medium-style reading optimization"
+  principles:
+    - "Typography exists to honor content"
+    - "Scale is mathematical — not arbitrary"
+    - "Vertical rhythm in 8px multiples"
+    - "Hierarchy through scale, not decoration"
+    - "Read before you design"

+  similarity:   "same function = identical visual treatment"
+  continuity:   "eye follows paths — guide attention"
+  closure:      "brain fills gaps — use sparingly"
+  figure_ground: "contrast establishes importance"

+# ─── LLM DESIGN MISTAKES — DETECT AND BLOCK ────────────────────────────────
+llm_mistakes:
+  - "Adding bold to headings (size creates hierarchy)"
+  - "Rounding scale values (36px → 35px — breaks mathematical scale)"
+  - "Spacing outside 8px grid (20px forbidden — use 16 or 24)"
+  - "Equal spacing everywhere (violates Gestalt proximity)"
+  - "Decorative colors (monochrome unless meaning requires color)"
+  - "Custom fonts without approval"
+  - "Shadows or gradients of any kind"
+  - "Centered body text (left-ragged only)"
+  - "More than 2 font families"
+  - "Modifying CSS/SVG without permission"

+# ─── SWISS INTERNATIONAL STYLE ─────────────────────────────────────────────
+swiss:
+  grid:       "mathematical — Müller-Brockmann principles"
+  typography: "left-aligned ragged right, max 2 fonts, sans-serif for UI"
+  hierarchy:  "scale-based — not color or weight decoration"
+  layout:     "asymmetric grid — avoid centered compositions"

Below is a unified git diff patch that implements the key improvements identified during the debugging session. The patch is split by file and can be applied directly to the MASTER2 repository.  

**Note**: Some changes, like splitting large files, are structural and require multiple new files. I’ve outlined the necessary additions and modifications; you may need to adjust paths and require statements according to your project layout.

From: MASTER2 Self-Improvement
Date: Mon, 23 Feb 2026 21:35:00 +0000
Subject: [PATCH] Self‑apply constitutional improvements

This patch addresses issues discovered by running MASTER2 on itself:

- Split oversized files (commands.rb, code_commands.rb) into logical modules.
- Fix bare `rescue` statements to use `rescue StandardError`.
- Halt pipeline when council vetoes.
- Make Replicate client return `Result` objects.
- Secure shell command execution by avoiding shell interpretation.
- Remove dead file `lib/llm/budget.rb`.
- Consolidate duplicate constants into YAML.
- Add missing module docstrings.
- Eliminate duplicate helper functions.

### Additional: Split `code_commands.rb` (outline)

Because `code_commands.rb` is also over 600 lines, I recommend splitting it into:
- `lib/commands/code/refactor.rb`
- `lib/commands/code/scan.rb`
- `lib/commands/code/fix.rb`
- `lib/commands/code/opportunities.rb`

Update `lib/commands/code_commands.rb` to require these new files and keep only the dispatcher.

---

### Running the Self‑Test

After applying these patches, run `bin/master self` to verify the improvements. The number of violations should drop significantly, and the council should no longer veto on structural grounds.

---

*The complete patch is large; the above snippets cover the most critical fixes. To apply, save the patch as a `.patch` file and run `git am` or `patch -p1 < file.patch`. Remember to test thoroughly.*

gistfile4.txt

MASTER2 can improve its self‑alignment by leveraging its own constitutional machinery in a continuous, governed feedback loop. The system already has the necessary components – axioms, enforcer, scanner, fixer, council, and self‑refactor – but they operate mostly on demand. To achieve lasting alignment, MASTER2 needs to **institutionalize self‑application** as an ongoing, autonomous process.

Below I outline a phased approach, grounded in the existing codebase, that would bring the system measurably closer to its own ideals.

---

### 1. Relevant Axioms for Self‑Alignment

| Axiom | Requirement |
|-------|-------------|
| **SELF_APPLY** | The system must meet its own quality standards. |
| **ONE_SOURCE** | Configuration and thresholds must live in YAML, not code. |
| **FAIL_VISIBLY** | All errors, including self‑refactor failures, must be logged. |
| **PRESERVE_THEN_IMPROVE_NEVER_BREAK** | Self‑changes must never break existing behavior. |
| **GUARD_EXPENSIVE** | Expensive self‑improvement runs should be rate‑limited. |

---

### 2. Continuous Self‑Monitoring

The `heartbeat` daemon (already in `lib/heartbeat.rb`) is the ideal vehicle. Add a new periodic check:

```ruby
# lib/heartbeat.rb
Heartbeat.register("self_monitor") do
  # Run a quick scan of the codebase (fast profile) every hour
  if Time.now.hour % 6 == 0   # every 6 hours
    result = Scan.run(MASTER.root, depth: :quick)
    if result[:total] > 0
      Logging.warn("self_monitor: #{result[:total]} violations detected")
      # Optionally queue a self‑refactor job
      Scheduler.add("self_refactor --auto", interval: :once)
    end
  end
end
```

This would surface newly introduced violations without user intervention.

---

### 3. Prioritised Self‑Refactoring

The existing `SelfRefactor` module (`lib/self_refactor.rb`) already runs `Evolve` over the codebase. However, it lacks a clear prioritisation mechanism. We can enhance it with a **violation‑aware ordering**:

```ruby
# In SelfRefactor.run, before calling Evolve, we first scan and group violations
violations = Scan.run(MASTER.root, depth: :deep)

# Group by severity (critical > major > minor) and by file
critical_files = violations[:by_file].select { |_, v| v.any? { |vi| vi[:severity] == :critical } }.keys

# Process critical files first, then major, etc.
(critical_files + major_files + minor_files).each do |file|
  Evolve.new.run(path: file, dry_run: false)   # but with budget control
end
```

This ensures the most harmful issues are fixed first.

---

### 4. Council Oversight for Core Changes

Some modifications touch the constitution itself (e.g., `data/axioms.yml`). The `SELF_APPLY` axiom should prevent the system from weakening its own standards. We can use the council as a **gatekeeper** for changes to core files:

```ruby
# In Staging.staged_modify (or in a pre‑commit hook)
if file.start_with?("data/")
  # Simulate council review on the diff
  diff = `git diff --cached #{file}`
  review = Council.council_review(diff, model: :strong)
  unless review[:passed]
    raise "Council vetoes change to #{file}: #{review[:vetoed_by].join(', ')}"
  end
end
```

This enforces **PRESERVE_THEN_IMPROVE_NEVER_BREAK** at the constitutional level.

---

### 5. Learning from Past Self‑Improvements

The `Learnings` module (`lib/learnings.rb`) already records patterns. We can extend it to store **successful self‑refactor patches**:

```ruby
# In SelfRefactor, after applying a fix, record it
if fix_applied && !dry_run
  Learnings.record(
    category: :self_improvement,
    pattern: Digest::SHA256.hexdigest(original_code + fixed_code),
    description: "Fixed #{violation[:axiom]} in #{file}",
    example: DiffView.unified_diff(original_code, fixed_code)
  )
end
```

When the same violation appears elsewhere, the system can replay the stored diff (or ask the LLM to adapt it), dramatically reducing future cost.

---

### 6. Guardrails to Prevent Oscillation

The `ConvergenceTracker` (`lib/convergence_tracker.rb`) already detects plateau and oscillation. We should **explicitly halt self‑refactor** when it starts oscillating and log a **friction event**:

```ruby
# In SelfRefactor.run
if ConvergenceTracker.should_halt?
  FrictionRecorder.record(:self_refactor_oscillation,
    iterations: history.size,
    last_delta: ConvergenceTracker.history.last[:violation_delta]
  )
  break
end
```

This prevents infinite loops and makes the system aware of its own inefficiency.

### 7. One‑Source Enforcement for Tuning Parameters

Currently, some thresholds (e.g., `MAX_FILE_LINES` in `lib/quality_gates.rb`) are hardcoded. We should move **all** tunable limits into `data/quality_thresholds.yml` and load them at runtime. For example:

```yaml
# data/quality_thresholds.yml
file_lines:
  warn: 500
  error: 600
  self_test_max: 600
```

Then in `QualityGates`:

```ruby
# lib/quality_gates.rb
def self.max_file_lines
  @config[:file_lines][:error] || 600
end
```

This directly satisfies **ONE_SOURCE**.

---

### 8. Self‑Test Completeness

The many skipped tests (`test/test_*.rb`) are a violation of **SELF_APPLY**. We can automatically generate test skeletons from the codebase using the LLM:

```ruby
# A new command: `master bootstrap_tests`
def bootstrap_tests
  untested_files = Dir["lib/**/*.rb"].reject do |f|
    test_file = f.sub("lib/", "test/").sub(".rb", "_test.rb")
    File.exist?(test_file)
  end
  untested_files.each do |src|
    prompt = "Generate a Minitest test file for:\n```ruby\n#{File.read(src)[0..1000]}\n```"
    result = LLM.ask(prompt)
    File.write(src.sub("lib/", "test/").sub(".rb", "_test.rb"), result.value[:content])
  end
end
```

This would dramatically increase coverage, though human review is still needed.

---

### 9. Dashboard for Alignment Trends

The `Dashboard` class (`lib/ui/dashboard.rb`) already shows constitutional alignment. Extend it to **track historical alignment**:

```ruby
# In lib/db_jsonl.rb, add an "alignment_snapshots" collection
def record_alignment_snapshot
  snapshot = {
    timestamp: Time.now,
    axiom_violations: Scan.run(MASTER.root, depth: :deep)[:total],
    file_count: MASTER.source_files.size,
    average_beauty: BeautyScorer.average_score(MASTER.source_files)
  }
  append("alignment_snapshots", snapshot)
end
```

The dashboard can then show a sparkline of alignment over time, motivating continuous improvement.

---

### 10. Putting It All Together: The Self‑Alignment Workflow

1. **Monitor** – Heartbeat runs a quick scan every few hours; if violations exceed a threshold, it schedules a self‑refactor job.
2. **Prioritise** – SelfRefactor groups violations by severity and processes critical files first.
3. **Execute** – Evolve attempts to fix each file, using LLM with strategies loaded from axioms.yml.
4. **Verify** – After each fix, the enforcer re‑runs to ensure the violation is gone.
5. **Learn** – Successful patches are stored in Learnings for future reuse.
6. **Govern** – Changes to constitutional files (`data/`) are veto‑checked by the council.
7. **Report** – The dashboard tracks progress and alerts if alignment deteriorates.

All of this is already possible with existing modules – they simply need to be wired together with a small amount of glue code.

---

### Concrete Next Steps for the Codebase

| Task | Files to Modify | Expected Outcome |
|------|-----------------|------------------|
| Add self‑monitor to heartbeat | `lib/heartbeat.rb` | Automatic violation detection |
| Extend SelfRefactor with prioritisation | `lib/self_refactor.rb` | Fixes most important issues first |
| Implement council gate for data/ changes | `lib/staging.rb` or `lib/hooks.rb` | Protects constitution from weakening |
| Store successful patches in Learnings | `lib/learnings.rb`, `lib/self_refactor.rb` | Faster fixes for repeated patterns |
| Move all thresholds to YAML | `lib/quality_gates.rb`, `data/quality_thresholds.yml` | ONE_SOURCE compliance |
| Generate missing tests | new command in `lib/commands/misc_commands.rb` | Improved test coverage |
| Add alignment snapshots | `lib/db_jsonl.rb`, `lib/ui/dashboard.rb` | Visible trend of self‑alignment |

Each of these tasks is small, self‑contained, and can be implemented incrementally. Together, they transform MASTER2 from a system that *can* apply its constitution into one that *continuously does so*.

---

The beauty of MASTER2 is that its own principles provide both the goal and the means. By turning the axioms inward and automating their enforcement, the system becomes a genuine example of **constitutional AI in action** – a developer partner that not only helps others write good code, but writes good code itself.

Below is a comprehensive list of 80 bug fixes, refinements, and opportunities for improvement to enhance MASTER2. This is derived from the deep review of the system's architecture, documentation (e.g., LLM.md), and common software engineering best practices. Items are categorized for clarity, prioritized by impact (High, Medium, Low), and include rationale, suggested fixes, and potential benefits. Many draw from the system's own axioms (e.g., FAIL_VISIBLY, ONE_SOURCE, SELF_APPLY) and documented "Gotchas" in LLM.md.

Implementation should follow the system's surgical improvement rule to avoid breaking changes. If you'd like details on any item or help creating a pull request for one, let me know!

gistfile7.txt

The pattern data is comprehensive. Let me cross-reference every top complaint against MASTER2's actual code.

---

## Your top recurring pain points, scored against MASTER2

The chat analysis from [3aacf904](https://claude.ai/chat/3aacf904-8b54-43f5-9170-2ed4636deccb) and [dc512d1c](https://claude.ai/chat/dc512d1c-2fc2-4ff0-ac66-6c7ccbf5bc32) identified these as the most-repeated requests. Here's what MASTER2 actually delivers on each one.

---

### 1. "Self-run and beautify" ⭐⭐⭐⭐⭐ — **Partially solved, but broken in practice**

This was your single most repeated request. MASTER2 has `SelfRefactor.run` callable via the `self` command, with `Scan.fix_all!` for mechanical normalisation and `Evolve` for LLM-guided passes. The infrastructure exists. However the patch we just applied exposed that the self-refactor loop was weaker than the user-code path — it didn't use `DependencyMap`, didn't run `SessionRetrospective` on stall, and processed the entire root dir as a blob instead of file by file. Those gaps are now closed. What remains: the `self` command doesn't emit a diff after each pass. The old master.yml always showed a "git-style diff showing changes" as output. MASTER2's `SelfRefactor` writes changes and logs iteration counts but the REPL never renders a before/after diff to the user. You'd have to run `git diff` yourself.

---

### 2. "Restore missing/lost logic from old chats" ⭐⭐⭐⭐⭐ — **Structurally solved by design**

This was chronic in the YAML era because each conversation started from scratch — context compressed, elements silently dropped. MASTER2 solves this architecturally: logic lives in versioned Ruby files under git, not in a floating config pasted into chat. The `data/exemplars.yml` captures positive patterns, `memory/axioms.jsonl` and `memory/costs.jsonl` persist across sessions, and `ProjectMemory` injects goal and decisions into every LLM call. You can no longer lose logic to compression mid-chat because the logic isn't in the chat. The gap that remains: `exemplars.yml` starts empty and only grows when `BeautyScorer` finds patterns above the `EXEMPLAR_THRESHOLD` — so on a fresh install, MASTER2 has no institutional memory of the patterns you'd accumulated over dozens of master.yml iterations.

---

### 3. "Will it actually execute?" / Description vs execution ⭐⭐⭐⭐⭐ — **Fully solved**

The deepest complaint in the YAML era: you kept asking "is this declarative or imperative?", "does it have actual detection logic?", "will this actually refactor anything?" Master.yml described what *should* happen; MASTER2 *is* the thing that happens. The `anti_simulation` block in `constitution.yml` directly encodes this: `forbidden_phrases: ["will", "would", "could", "might"]`, `required_evidence: {file_read: "Show content with SHA256", modification: "Show diff"}`. The `PressurePass` runs adversarial review. The `Executor` uses ReAct/PreAct/ReWOO patterns that observe actual tool outputs. This is the most complete resolution of any of your recurring complaints.

---

### 4. "Complete adversarial validation — 10 personas, weights, veto, question banks" ⭐⭐⭐⭐ — **Expanded but question banks missing**

Master.yml had 6–8 personas; you kept asking for 10 with explicit question banks per persona. MASTER2 has 12 personas in `council.yml` with individual model assignments, weight scores, and 3 veto roles (security, attacker, maintainer). That's better than you ever got from the YAML. What's gone: the per-persona question banks. Master.yml had things like the attacker asking "how can I abuse this?" followed by a list of 6 specific questions, the minimalist running a Dieter Rams checklist, the scale persona challenging growth scenarios. `council.yml` has `directive` blocks per persona but they're paragraphs, not structured question banks. The `data/questions.yml` file exists for phase-level questions but there's no per-persona question set driving the deliberation. The council says *what* each persona thinks — it doesn't run them through their question list systematically.

---

### 5. "8-phase workflow with question banks and exit criteria" ⭐⭐⭐⭐ — **7 phases, questions present, exit criteria thin**

You wanted discover → analyze → design → implement → validate → document → reflect → deliver with full question banks and gate criteria. MASTER2's `phases.yml` has 7 phases (drops "document" and "reflect" as standalone, folds them into validate and deliver), with introspection questions per phase. The `workflow/planner.rb` and `workflow/engine.rb` implement the progression. What's missing: explicit exit criteria (the gate conditions that prevent advancing until outputs are verified), and the "document" and "reflect" phases you specifically kept asking to restore. The retrospective that document/reflect represented lives in `SessionRetrospective` but it's not wired into the workflow as a mandatory gate — it's a session-end optional synthesis.

---

### 6. "Anti-simulation / false commits — show it happened, don't claim it" ⭐⭐⭐⭐ — **Codified in constitution but not enforced at runtime**

This was one of your most emotionally charged complaints: LLMs saying "done!" with no diff. `constitution.yml` explicitly bans this:

```yaml
anti_simulation:
  forbidden_phrases: ["will", "would", "could", "might"]
  required_evidence:
    modification: "Show diff"
    file_read: "Show content with SHA256"
```

But this is a data file that the LLM reads as system context — it's not runtime enforcement. Nothing in the pipeline checks whether a response claims an action without providing evidence. `PressurePass` could catch this (it generates counterarguments and failure modes), but it was opt-in and therefore effectively dead until today's patch flipped the default. With pressure pass now active by default, a claim-without-evidence in the candidate answer will get challenged adversarially before it reaches you. That's the closest thing to runtime enforcement that exists.

---

### 7. "DRY and ultraminimalism — zero tolerance for redundancy" ⭐⭐⭐⭐ — **Enforced outward, violated inward**

The `ONE_SOURCE` axiom is priority 10, protected. The enforcer runs DRY checks. The Strunk stage strips hedging from output. But as the initial analysis showed, MASTER2 has 60+ files in `lib/` against its own "target 15–25" rule, `commands.rb` and `code_commands.rb` are each over 600 lines against the ZEN_METHOD axiom, and `Swarm` and `Council::Deliberation` implement the same fan-out/arbiter pattern twice. The system enforces DRY on code it reviews but is not yet DRY itself. The self-refactor machinery now points at this properly — this is the gap that running `self` with the patched version should close over time.

---

### 8. "Information architecture / inverted pyramid — most important first" ⭐⭐⭐ — **Axiom exists, stage exists, not enforced on MASTER2 itself**

The `INVERTED_PYRAMID` axiom is priority 9, protected. `lib/stages/reflow.rb` handles this for user code. The `reflow` command reorders file contents by importance. `constitution.yml`'s `structural_analysis` section documents the hierarchy. But `master.rb` itself loads things in an order driven by dependency, not importance — the public API (the REPL commands users actually type) is buried deep after 30+ internal requires. The enforcer's `check_conceptual` layer detects when private methods precede public ones within a file but doesn't enforce file-level ordering across the module. MASTER2 knows the principle, applies it to user files, and doesn't apply it to its own boot sequence.

---

### 9. "Domain-specific patterns — Ruby/Rails, zsh, OpenBSD" ⭐⭐⭐ — **zsh/OpenBSD good, Rails absent**

`data/language_rules.yml`, `data/language_detection.yml`, and `lib/review/enforcer/language_axioms.rb` handle language-specific enforcement. The zsh patterns file has forbidden-to-allowed mappings (`find` → `zsh glob`, `sed` → parameter expansion, `awk` → arithmetic). `lib/pledge.rb` implements OpenBSD pledge/unveil. But Rails-specific patterns — the callback side-effects, N+1 query recovery, `include` vs `eager_load` semantics, ActiveRecord scope composition — are absent. This was a significant chunk of master.yml's domain section. MASTER2 has generic Ruby axioms but nothing Rails-aware.

---

### 10. "Convergence/oscillation detection — auto-iteration with quality delta" ⭐⭐⭐ — **Well-implemented but not adaptive**

`ConvergenceTracker` detects stall (2 consecutive zero-delta iterations), oscillation (sign-alternating deltas over 3 iterations), and autofix rate collapse. This is genuinely good. The gap: when oscillation is detected, the loop stops — it doesn't change strategy. Your original request was for the system to *respond* to oscillation by trying a different approach (different tier, different persona, manual review flag). The `synthesize_retrospective` call in the patched `SelfRefactor` is the first step toward that, but the loop doesn't yet read the retrospective output and adjust its next iteration's strategy based on it.

---

### 11. "Progress display — dmesg format, spinners, silent success/loud failure" ⭐⭐⭐ — **Implemented but fragmented**

`lib/logging/dmesg.rb` implements the `svc[pid]: level: msg` format. `lib/ui/spinner.rb` has spinners. Boot output is dmesg-style. The `constitution.yml` documents the communication style. What you always wanted was one centralized specification that all output conforms to — the "braille spinner `⠋⠙⠹⠸⠼⠴⠦⠧⠇⠏`", the response footer format `10p✓ · v17 · Δ-15 · 0smell`, "silent success / loud failure" as a hard rule. The spec is in `constitution.yml` as YAML documentation, but there's no runtime assertion that checks whether a log line conforms to the format. And the braille spinner from master.yml is completely gone — `ui/spinner.rb` uses a different set.

---

### 12. "No file sprawl — edit in place, never create new files" ⭐⭐ — **Documented but unenforced**

The enforcer's `ARCHITECTURE` rules say "no new files without justification" and "new file only justified if would exceed 200 lines when added to existing code." But this is a comment in `review/enforcer.rb`, not a gate. Nothing blocks `SelfRefactor` or `MultiRefactor` from creating new files. The `file_processor.rb` can write new files freely. In the YAML era you complained about LLMs creating file proliferation; MASTER2 has 60+ lib files with the same instinct. The guard is wisdom, not enforcement.

---

**The verdict:** The three things MASTER2 genuinely solved — description-vs-execution, version durability (no more "restore missing logic"), and the constitutional architecture — were the deepest structural problems. The things still outstanding are mostly about self-application: the system builds excellent scaffolding for catching others' mistakes and doesn't yet run all of it on itself. The council question banks, Rails domain patterns, adaptive oscillation response, and the missing `self` diff output are the most actionable gaps from your recurring complaints.
