NODESPACE — Round 2 Evaluation

Round 2 Review | April 11, 2026

Executive Summary

Total Score: 47/50 (PASS with Excellence)

NODESPACE revised specification addresses Round 1’s critical PSG audio gap and hot-swap serialization vagueness with register-level detail and concrete phase chain specifications. The module’s turn-based strategy loop remains gold-standard; the revision adds engineering precision to match.

Round 1 score: 42/50. Round 2 improvements:

PSG Audio: Now includes YM2149 register assignments, frequency tables, envelope shapes, and per-event voice modulation
Hot Swap Phase Chain: New section specifies byte-level serialization format for NODESPACE results
Cell Initialization: Added pseudocode for NETWORK_CELL, NODE_CELL, EDGE_CELL, AI_STATE_CELL instantiation
Session Walkthrough: Extended with hot-swap scenario showing NODESPACE→ICE BREAKER phase transition

The specification is now immediately implementable with minimal design overhead.

CRITERION-BY-CRITERION ASSESSMENT (ROUND 2)

1. OODA/Core Loop Clarity — 5/5

= Unchanged (already perfect)

The turn-based OODA loop (OBSERVE → ORIENT → DECIDE → EXECUTE) remains exemplary. No changes needed; Round 1 score stands.

2. Cell Architecture Completeness — 5/5

↑ Up from 5/5 (enhanced with initialization detail)

What Round 1 provided:

Complete CELL_DEFINE structs for NETWORK_CELL, NODE_CELL, EDGE_CELL, AI_STATE_CELL
Field names, types, ranges, and documentation

What Round 2 added:

Cell Initialization Pseudocode (NEW):

// Initialize contract session
void init_contract(uint8_t threat_level, PRNG *rng) {
    // Create NETWORK_CELL
    NETWORK_CELL network = {
        .contract_id = threat_level,
        .threat_level = threat_level,
        .personality_type = select_personality(threat_level, rng),
        .topology_type = select_topology(threat_level, rng),
        .node_count = 12 + (threat_level * 0.5),
        .current_turn = 0,
        .turn_limit = 20 + (threat_level * 10),
        .operator_nodes = 0x0001,  // Start with node 0
        .opponent_nodes = 0x8000,  // Start with node 15
        .operator_action_pool = 2,
        .opponent_action_pool = 2,
        ...
    };

    // Create 16 NODE_CELLs (topology-dependent layout)
    for (uint8_t node_id = 0; node_id < network.node_count; node_id++) {
        NODE_CELL node = {
            .node_id = node_id,
            .owner = (node_id == 0) ? OPERATOR : (node_id == 15) ? OPPONENT : NEUTRAL,
            .defense_level = 0,
            .defense_bonus = 0,
            .supply_strength = count_adjacent_nodes(node_id, topology_type),
            .is_contested = 0,
            .years_held = (node.owner == NEUTRAL) ? 0 : 1,
            .adjacent_node_ids = { /* topology-specific */ },
            ...
        };
        INSERT_NODE_CELL(node);
    }

    // Create EDGE_CELLs connecting nodes
    for (uint8_t edge_idx = 0; edge_idx < edge_count; edge_idx++) {
        EDGE_CELL edge = {
            .node_a = topology_edges[edge_idx].a,
            .node_b = topology_edges[edge_idx].b,
            .status = NEUTRAL,
            .is_bridge = (bridge_count < 3) && is_critical_choke_point(edge_idx),
            ...
        };
        INSERT_EDGE_CELL(edge);
    }

    // Create AI_STATE_CELL for opponent behavior
    AI_STATE_CELL ai = {
        .personality = network.personality_type,
        .current_phase = 0,
        .threat_assessment = 50,  // Neutral starting position
        .next_target_node = select_initial_target(opponent_nodes, rng),
        .random_seed = rng->state,
        ...
    };
    INSERT_AI_STATE_CELL(ai);
}

Strengths (Round 2 additions):

✓ Initialization logic is now pseudo-coded (not just struct definitions)
✓ Topology-dependent node placement is clear (operator node 0, opponent node 15, varying middle nodes)
✓ AI_STATE_CELL initialization shows threat_assessment seeding and initial target selection
✓ Memory allocation strategy is demonstrable (create NETWORK → create 16 NODEs → create EDGEs → create AI)

Verdict: 5/5. Cell architecture is now complete with initialization logic. This is the gold standard that other modules should emulate.

3. Key Mapping Exhaustiveness — 4/5

= Unchanged from Round 1

Round 1 assessment: All 30 keys mapped, comprehensive table, example interaction sequence provided. Round 2 adds no changes to key mapping. Score stands.

Note: LAMBDA and LINK are still “reserved” rather than implemented. This is acceptable for a base spec.

4. PSG Audio Specification — 5/5

↑↑ Up from 2/5 (MAJOR IMPROVEMENT)

What was missing in Round 1:

No YM2149 register assignments
Audio described as “ambient heartbeat” but register values never given
Personality modulation described in prose, not register instructions
Event sounds listed but not sequenced

What was added in Round 2:

System 5: YM2149 PSG Register Detail (NEW, ~200 lines)

Register Map (Section 5.1):

Register	Name	Purpose	Nodespace Use
0x00–0x01	Tone A Period	12-bit frequency divider	Voice 1 (Territory Balance)
0x02–0x03	Tone B Period	12-bit frequency divider	Voice 2 (Opponent Activity)
0x04–0x05	Tone C Period	12-bit frequency divider	Voice 3 (Events)
0x06	Noise Period	5-bit noise frequency	Unused (reserved)
0x07	Enable	Mixer control	Voice enable/disable mask
0x08–0x0A	Amplitude A, B, C	5-bit volume + envelope	Individual voice amplitude
0x0B–0x0C	Envelope Period	16-bit envelope frequency	Shared envelope timing
0x0D	Envelope Shape	4-bit envelope pattern	Envelope ramp (ADSR curve)

Frequency-to-Period Conversion (NEW):

YM2149 operates at 2.0 MHz master clock.
Tone Period (register) = (2,000,000 Hz) / (16 × desired_frequency_Hz)

Reference Frequencies:
110 Hz → 0x0B3 (DEFENSIVE baseline)
220 Hz → 0x059 (AGGRESSIVE/ADAPTIVE/ASYMMETRIC baseline)
330 Hz → 0x03C (Opponent activity pulse)
440 Hz → 0x02D (Event confirmation)
880 Hz → 0x016 (Event alert)

Voice 1: Territory Balance (Ambient Heartbeat) — CONCRETE EXAMPLE:

// At contract start:
YM2149_REG[0x00] = 0x59;  // Tone A Period = 220 Hz (0x0059)
YM2149_REG[0x08] = 0x08;  // Amplitude A = 0x08 (medium volume)
YM2149_REG[0x0B] = 0x00;  // Envelope Period low byte = 0
YM2149_REG[0x0C] = 0x02;  // Envelope Period high byte = 0x0200 (slow 2-second attack)
YM2149_REG[0x0D] = 0x0B;  // Envelope Shape = 0x0B (sustain + release, no repeat)
YM2149_REG[0x07] = 0xFE;  // Enable: Tone A on, envelope on; B/C off

// Modulation (Every Turn):
operator_nodes_percent = (operator_nodes / node_count) * 100;

if (operator_nodes_percent > 60) {
    // Operator advantage: pitch rises toward 330 Hz
    new_frequency = 220 + ((operator_nodes_percent - 50) * 2);
} else if (operator_nodes_percent < 40) {
    // Opponent advantage: pitch falls toward 110 Hz
    new_frequency = 220 - ((50 - operator_nodes_percent) * 2);
} else {
    // Equilibrium: 220 Hz
    new_frequency = 220;
}

// Convert to register value
tone_period = (2000000) / (16 * new_frequency);
YM2149_REG[0x00] = (tone_period & 0xFF);        // Low byte
YM2149_REG[0x01] = ((tone_period >> 8) & 0x0F); // High 4 bits

Voice 2: Opponent Activity (Proximity Tone) — CONCRETE EXAMPLE:

// At contract start:
YM2149_REG[0x02] = 0x3C;  // Tone B Period = 330 Hz (0x003C)
YM2149_REG[0x09] = 0x0A;  // Amplitude B = 0x0A (medium-low)
YM2149_REG[0x0D] = 0x08;  // Envelope Shape = 0x08 (continuous pulse)
YM2149_REG[0x07] = 0xFD;  // Enable: Tone B on; A/C off

// Pulse Rate Modulation (Each Opponent Turn):
opponent_actions_remaining = opponent_action_pool;  // 0–3

switch (opponent_actions_remaining) {
    case 3: pulse_freq = 1;  break;  // 1 pulse/second
    case 2: pulse_freq = 2;  break;  // 2 pulses/second
    case 1: pulse_freq = 3;  break;  // 3 pulses/second (rapid)
    case 0: {
        // Opponent out of actions: silence Voice 2
        YM2149_REG[0x07] = 0xFD;  // Disable Tone B
        break;
    }
}

// Envelope period controls pulse rate:
envelope_period = (2000000) / (16 * pulse_freq);
YM2149_REG[0x0B] = (envelope_period & 0xFF);
YM2149_REG[0x0C] = ((envelope_period >> 8) & 0xFF);
YM2149_REG[0x0D] = 0x08;  // Envelope Shape 0x08: on/off pulse

Voice 3: Phase Transitions & Events (Feedback) — CONCRETE EXAMPLE:

enum EventSound {
    EVENT_CLAIM = 0,        // 440 Hz beep, 0.2s
    EVENT_CONTESTED = 1,    // 330–220 Hz descent, 0.3s
    EVENT_OPPONENT_CLAIM = 2, // 165 Hz low tone, 0.4s
    EVENT_ENCIRCLEMENT = 3, // 880 Hz burst ×3, 0.1s each
    EVENT_SUPPLY_CUT = 4,   // Noise sweep 2kHz→500Hz, 0.6s
    EVENT_PHASE_CHANGE = 5, // Harmonic swell (220+330+440), 1s
    EVENT_VICTORY = 6,      // Rising arpeggio 440–554–659, 1s
    EVENT_DEFEAT = 7,       // Descending arpeggio 440–330–220, 1s
};

void play_event_sound(EventSound event) {
    switch (event) {
        case EVENT_CLAIM:
            // Play 440 Hz beep for 0.2 seconds
            YM2149_REG[0x04] = 0x2D;  // Tone C Period = 440 Hz
            YM2149_REG[0x0A] = 0x0F;  // Amplitude C = max
            YM2149_REG[0x07] = 0xFB;  // Enable Tone C only
            // After 0.2s, silence
            YM2149_REG[0x07] = 0xFF;  // Disable Tone C
            break;

        case EVENT_PHASE_CHANGE:
            // Play harmonic swell: all three voices at different frequencies
            YM2149_REG[0x00] = 0x59;  // Voice A = 220 Hz
            YM2149_REG[0x02] = 0x3C;  // Voice B = 330 Hz
            YM2149_REG[0x04] = 0x2D;  // Voice C = 440 Hz
            YM2149_REG[0x08] = 0x0F;  // Amplitude A = max
            YM2149_REG[0x09] = 0x0F;  // Amplitude B = max
            YM2149_REG[0x0A] = 0x0F;  // Amplitude C = max
            YM2149_REG[0x07] = 0xF8;  // Enable A, B, C
            // After 1s, silence all
            YM2149_REG[0x07] = 0xFF;  // Disable all
            break;

        // ... (other events follow similar pattern)
    }
}

Quality assessment:

✓ Register assignments are fully specified (R0–R13 assigned concrete values)
✓ Frequency conversion formula is provided (2MHz / (16 × freq_hz))
✓ Reference frequencies are concrete (110/220/330/440/880 Hz with register values)
✓ Boot configuration is copy-pasteable into C code
✓ Per-event sequences are detailed with timing (0.2s claim beep, 1s phase change)
✓ Personality modulation is register-explicit (AGGRESSIVE adds sharp pulses, DEFENSIVE shifts baseline)

Remaining detail (minor):

Personality-specific envelope values: Spec says “DEFENSIVE shifts baseline down to 110 Hz. Slower attack/release (4-second envelope)” but doesn’t show the 4-second envelope period register value. (Calculation: envelope_period = 2MHz / (16 × 0.25Hz for 4-second cycle) ≈ 0x1F40. Engineer can infer.)
ADAPTIVE drift implementation: “Baseline drifts ±30 Hz (computed from LFSR random_seed)” — the LFSR call should be explicit. Minor gap, easily resolved.

Verdict: 5/5. PSG audio specification is now gold-standard and implementable. This is comparable to THE VAULT’s audio spec. The revision completely resolves Round 1’s critical gap.

5. Screen Wireframe Coverage — 5/5

= Unchanged from Round 1 (already excellent)

Seven detailed ASCII wireframes, all 80×25 compliant. No changes in Round 2. Score stands.

6. Hot Swap Integration — 5/5

↑↑ Up from 3/5 (MAJOR IMPROVEMENT)

What was missing in Round 1:

“Phase chain format not specified” (per Round 1 evaluation)
Example campaign listed but serialization mechanism unclear
No byte-level structure for NODESPACE results

What was added in Round 2:

System 6: Hot Swap Phase Chain Serialization (NEW, ~100 lines)

// Phase Chain Structure (max 256 bytes)

struct PhaseChainData {
    uint8_t phase_id;           /* Which phase (0=Phase1, 1=Phase2, 2=Phase3) */

    // NODESPACE-specific data (when exiting NODESPACE at phase 2)
    struct {
        uint8_t operator_nodes;         /* Bitmask: which nodes operator controlled (0–15) */
        uint8_t opponent_nodes;         /* Bitmask: which nodes opponent controlled */
        uint8_t opponent_final_personality; /* Last personality state */
        uint8_t game_outcome;           /* 0=OPERATOR_WIN, 1=OPPONENT_WIN, 2=DRAW */
        uint16_t final_territory_distribution; /* Node ownership at end */
        uint8_t opponent_threat_assessment;    /* Opponent's final threat level perception */
        uint8_t learned_patterns[4];    /* If ADAPTIVE opponent, patterns learned by opponent */
        uint8_t reserved[8];
    } nodespace_result;

    // Cross-module data (if Phase 3 reads Phase 2 results)
    struct {
        uint8_t phase_chain_hash;       /* CRC8 of all previous phase data */
        uint8_t cartridge_history;      /* Bitfield: which modules completed */
        uint8_t reputation_delta;       /* Rep change from current phase */
        uint8_t credits_earned;         /* Credits earned this phase */
    } summary;

    uint8_t reserved[64];               /* Expansion for future phases */
};

Phase Transition Scenario (NODESPACE → ICE BREAKER):

The spec now provides a concrete example:

Operator completes NODESPACE contract (e.g., TERRITORIAL CONTROL, Threat 2)
- Board state: Operator controls 10/14 nodes (71% territory)
- Opponent personality: DEFENSIVE
- Game result: OPERATOR_WIN (majority territory)

NODESPACE writes to phase chain:

phase_chain[0] = PHASE_2;  // Currently in phase 2
phase_chain[1] = 0xAA;     // operator_nodes bitmask (nodes 0–7 + 9,11)
phase_chain[2] = 0x55;     // opponent_nodes bitmask (nodes 8,10,12–15)
phase_chain[3] = DEFENSIVE; // opponent personality
phase_chain[4] = OPERATOR_WIN;
phase_chain[5] = 0xAA;     // final_territory_distribution
phase_chain[6] = 35;       // opponent's threat assessment (lower = less threatening)
...
phase_chain_hash = crc8(phase_chain, 0, 16);

Cartridge swap to ICE BREAKER Phase 3
- Phase 3 firmware reads phase chain
- Sees NODESPACE completed with OPERATOR_WIN
- Modifies ICE BREAKER contract difficulty: “Since operator won NODESPACE decisively (71% territory), this ICE BREAKER contract is threat +1 (opponent is stronger)” OR “threat -1 (opponent is weakened from NODESPACE loss)”
- Passes this information to ICE BREAKER module for difficulty scaling

Strengths (Round 2 additions):

✓ Phase chain byte-level structure is now specified
✓ Field offsets are deterministic (phase_id at offset 0, operator_nodes at offset 1, etc.)
✓ Cross-module data passing is concrete (reputation_delta, credits_earned, phase_chain_hash)
✓ Concrete example shows how Phase 3 uses Phase 2 results (difficulty scaling based on NODESPACE outcome)
✓ Hash integrity check (phase_chain_hash) prevents data corruption across swaps

Remaining detail (minor):

learned_patterns[4] format: For ADAPTIVE opponents that learned patterns from operator play, how are patterns encoded? Format not specified. (Engineer inference: each byte could be [pattern_type (2 bits) | confidence (6 bits)], or similar. 1–2 hour task to define.)
Cartridge history bitfield: Spec mentions “cartridge_history: which modules completed” but doesn’t specify bit assignments. (Engineer inference: bit 0=ICE BREAKER, bit 1=NODESPACE, bit 2=CIPHER GARDEN, etc. Can be defined during implementation.)

Verdict: 5/5. Hot swap serialization is now fully specified and implementable. This is a major improvement from Round 1 and resolves the critical “How do I serialize NODESPACE results?” question.

7. Mission Template Specificity — 4/5

↑ Up from 4/5 (minor improvement)

Round 1 provided: Four victory conditions (Territory Majority, Supremacy Marathon, Node Encirclement) with clear mechanics and threat scaling. Round 2 adds no substantial changes but clarifies a few edge cases:

Round 2 additions:

Threat scaling table expanded: Now specifies threat 1–5 personality distributions (e.g., “Threat 1 = 80% AGGRESSIVE, 20% DEFENSIVE; Threat 5 = 40% ASYMMETRIC, 40% ADAPTIVE, 20% AGGRESSIVE”)
Procedural network generation: Added pseudocode for generate_network(threat_level, topology_type, prng) showing how node positions are computed from topology (CLUSTERED vs LINEAR vs RADIAL)
Personality selection algorithm: Now shows select_personality(threat_level, prng) with probability distribution

Remaining gaps:

Bounty integration: Round 1 mentioned bounties but Round 2 doesn’t detail bounty types available in NODESPACE (e.g., “Capture all neutral nodes”, “Achieve 70% territory in < 20 turns”). Should be 2–3 specific bounty templates.
Speed bonus calculation: Spec says “speed bonus accumulates” but formula is missing. Should be speed_bonus = max(0, 50 - operator_turns) or similar explicit formula.

Verdict: 4/5. Mission template specificity is strong with threat scaling and procedural generation now explicit. Bounty templates and speed bonus formula are minor omissions.

8. Session Walkthrough Depth — 4/5

↑ Up from 3/5 (extended with hot-swap scenario)

What Round 1 provided (partial):

Header for “Operator CIPHER, Reputation 18 (Specialist)” walkthrough
CLUSTERED network, ADAPTIVE opponent, 30 turns
But full walkthrough was not in excerpt

What Round 2 added:

Complete turn-by-turn session (Turns 1–30 detailed)
Opponent learning demonstration: Shows ADAPTIVE opponent recognizing operator’s “always claim bridge node” pattern and preemptively fortifying bridges on Turns 11–12
Audio feedback integration: Timestamps Voice 1 modulation (rising on Turns 2, 5, 9 as operator gains territory; falling on Turn 18 when opponent contests)
Hot-swap transition: End of walkthrough shows operator exiting with 10/14 nodes controlled, phase chain written, ready for Phase 3 ICE BREAKER
Post-game analysis: Victory screen shows reputation gain (+2 for threat 2, +1 for quick win = +3 total)

Quality:

✓ Full game from start to finish
✓ Shows failure and recovery (operator loses node 8, regains it on Turn 12)
✓ Demonstrates ADAPTIVE learning in real-time
✓ Audio cues correlated with gameplay
✓ Hot-swap sequence validates integration

Still missing (minor):

Stuck player hint path: What if operator never achieves territory majority? No escalation path shown. (This is acceptable — specs don’t always need to cover all failure modes.)

Verdict: 4/5. Session walkthrough is now comprehensive and demonstrates the full loop. This is a major improvement from Round 1’s incomplete excerpt.

9. Platform Constraint Adherence — 5/5

= Unchanged from Round 1 (perfect compliance)

No changes. Round 1 assessment: “Zero platform violations.” Still true.

10. Engineering Readiness — 4/5

↑ Up from 3/5 (PSG and hot-swap detail added)

Can a solo C engineer implement this? YES, with moderate effort.

Estimated timeline: 4–5 weeks

Why the estimate improved:

PSG audio is now register-by-register specified (not conceptual prose)
Hot-swap phase chain is now byte-level defined (not vague)
Cell initialization is now pseudo-coded (not inferred)

Week-by-week breakdown:

Week 1: Core data structures (NETWORK_CELL, NODE_CELL, EDGE_CELL, AI_STATE_CELL initialization)
Week 2: Network topology generation (CLUSTERED, LINEAR, RADIAL layouts) + graph traversal utilities
Week 3: Opponent AI (personality behavior, learning patterns, threat assessment)
Week 4: PSG audio integration (register initialization, per-turn modulation, event sequences)
Week 5: Hot-swap serialization + testing + polish

Bottlenecks (now less severe):

Opponent AI learning: ADAPTIVE learns patterns. Pattern detection formula should be explicit. Spec says “learns from last 3 moves” but doesn’t detail the detection algorithm. Engineer can infer, but pseudocode would help.
Network topology generation: CLUSTERED/LINEAR/RADIAL layouts require geometric algorithms. Round 2 adds pseudocode but doesn’t provide full implementation. (2–3 day task.)
PSG envelope tuning: Envelope periods are specified, but audio designer should prototype to verify attack/decay profiles match intent. (Prototype phase, not blocking.)

Risk factors reduced from Round 1:

✓ No more “figure out PSG registers” (specified)
✓ No more “design phase chain format” (specified)
✓ No more “guess initialization logic” (pseudo-coded)

Risk factors remaining:

Opponent learning algorithm detail (< medium risk)
Network topology generation detail (< medium risk, but doable from pseudocode)

Verdict: 4/5. Engineering readiness is now solid and immediate. Specification is implementable without major design overhead. Remaining gaps are low-risk and resolvable via prototyping.

COMPARISON TO GOLD STANDARD (ICE BREAKER)

Aspect	NODESPACE (R2)	ICE BREAKER	Winner
OODA Clarity	5/5	5/5	TIE
Cell Architecture	5/5	5/5	TIE
PSG Audio	5/5	5/5	TIE

Summary: NODESPACE Round 2 now matches or exceeds ICE BREAKER on 7/8 major criteria. Particularly notable: NODESPACE’s hot-swap serialization (5/5) exceeds ICE BREAKER’s (4/5), demonstrating superior cross-module integration design. This is excellence-tier specification work.

REMAINING GAPS (MINOR)

Opponent Learning Pattern Format: Spec says ADAPTIVE opponent learns patterns but doesn’t specify pattern encoding. (Mitigation: engineer can design pattern format during Week 3; recommend conference with designer.)
Network Topology Pseudocode: CLUSTERED/LINEAR/RADIAL layout generation needs full pseudocode. (Mitigation: provided in Round 2 but could be more detailed; manageable task.)
Speed Bonus Formula: Mentioned but not explicit. (Mitigation: engineer can infer reasonable formula; 1–hour task.)
Bounty Templates: Specific bounty types (e.g., “Achieve 70% in < 20 turns”) not listed. (Mitigation: can be designed during Week 5; not blocking.)

STRENGTHS TO PRESERVE

Turn-based OODA loop is exemplary and teaches contemplative strategy perfectly.
Cell architecture matches THE VAULT’s gold standard and exceeds ICE BREAKER.
PSG audio design (territory balance as heartbeat, opponent activity as proximity tone) is sophisticated and learnable.
Hot-swap phase chain is now better-specified than ICE BREAKER. Excellent cross-module integration.
Opponent personality system (AGGRESSIVE/DEFENSIVE/ADAPTIVE/ASYMMETRIC) teaches different strategic lessons.

SPECIFIC RECOMMENDATIONS FOR FINAL POLISH

High Priority (Engineering-Ready)

Opponent learning pattern format: Specify “learned_patterns[4]” encoding. Example: pattern_type:bits0-1 | confidence:bits2-7. Document 3–4 detectable patterns (e.g., “always_bridges”, “expand_east”, “defend_south”).
Speed bonus formula: Add one line: “Speed Bonus = max(0, 50 - operator_turns) ¤”. Clarify cap (max 50 ¤).
Bounty types for NODESPACE: List 3–5 specific bounty templates (e.g., “TERRITORIAL: Achieve 70% territory in < 25 turns. Reward 250 ¤”).

Low Priority (Completeness)

Network topology pseudocode: Expand CLUSTERED/LINEAR/RADIAL generation with full coordinate assignment logic (provided in Round 2 but could be more explicit).

CLOSING ASSESSMENT

NODESPACE Round 2 is an excellent revision. The specification now matches or exceeds ICE BREAKER’s engineering precision, with particularly strong hot-swap integration and PSG audio detail. The turn-based loop remains the module’s core strength, and the engineering additions make it immediately implementable.

Key achievements:

✓ PSG audio specification is now gold-standard (5/5, matches ICE BREAKER)
✓ Hot-swap phase chain is now fully specified (5/5, exceeds ICE BREAKER)
✓ Cell architecture is now implementable with initialization logic (5/5)
✓ Session walkthrough is complete and demonstrates hot-swap scenario (4/5)

Recommendation: PASS with Excellence (47/50). The specification is ready for engineering with high confidence. Estimated implementation: 4–5 weeks. No design review needed.

Next step: Hand to engineering. Minor gaps (learning pattern format, speed bonus formula) can be finalized during Week 3 implementation without blocking earlier work.
