1 — Purpose#

This file is a navigation guide. It helps students find a path through the D369 Chip Spec module that matches their background, their curiosity, and their available time.

The module contains 17 files, 76 numbered identifiers, and 182 checklist items. That is a lot of surface area. No student needs all of it at once, and no single reading order works for everyone.

This file provides:

  • Four background-specific paths — tailored reading sequences for different starting points
  • Three depth levels — newcomer, intermediate, and advanced
  • Milestone markers — what a student should be able to explain after each stage
  • Entry guidance — where this module sits in the broader adoption timeline

It does not provide a curriculum, a syllabus, or a certification. It is a map, not a school.


2 — Who This File Is For#

Any student who has arrived at the D369 module and wants to know where to start.

No prerequisites. You do not need to know RTT. You do not need to know chip design. You do not need to know TriadicFrameworks. You need curiosity and the willingness to read carefully.

If you already know chip architecture, you will move faster. If you do not, the module was written to meet you where you are. Every file was drafted to be engineer-facing and student-ready.

See FAQ.md §12 (Q12.1–Q12.7) for quick answers to the seven most common student questions.


3 — Before You Begin#

3.1 — The One Sentence#

If you remember nothing else from the D369 module:

"Nothing here tells us what to build — only what not to erase."

That sentence is the entire specification in one breath. Everything else is detail.

3.2 — The Building Metaphor#

The D369 module asks chip manufacturers to do something simple: when you build a building, run empty conduit in the walls. You do not have to pull wire through it. You do not have to connect it to anything. You just leave room.

That is what structural observability reservation means. Reserved space. No behavior. No promises. Just space that is cheaper to include now than to retrofit later.

See README.md for the full building metaphor — a 9-floor tower with an electrical system.

3.3 — Three Tags#

The entire specification reduces to preserving three metadata tags:

-
┌──────────────────────────────────────────┐
│         Three Structural Tags            │
├──────────────────────────────────────────┤
│                                          │
│  1. Source ID                            │
│     Who produced this signal?            │
│     (static, assigned at design time)    │
│                                          │
│  2. Lifecycle State                      │
│     What phase is this signal in?        │
│     (externally writable, not inferred)  │
│                                          │
│  3. Monotonic Time                       │
│     When did this happen?                │
│     (non-resettable within clock domain) │
│                                          │
└──────────────────────────────────────────┘

If you understand those three tags, you understand what the specification preserves. Everything else — the 12 requirements, the 182 checklist items, the diagrams — exists to ensure those three tags survive the design process.


4 — Learning Paths by Background#

Four paths are provided below. Each is a reading sequence through the module's files, ordered to match how a student from that background would naturally approach the material.

You do not need to pick the "right" path. Pick the one closest to your background. If none fits, use Path D (Interdisciplinary). If you switch mid-stream, that is fine — every file stands alone.


Path A — Electrical Engineering / Hardware Design#

You already know: RTL, synthesis, timing closure, DFT, physical design flows. You will recognize: The checklist structure, the design review format, the "what not to erase" framing. Your instinct: "Show me the requirements and the review checklist."

Reading Sequence#

Step File Why This Order
A1 README.md Module overview, building metaphor, structural orientation
A2 Spec_Overview.md Executive-level specification summary — your 10-minute brief
A3 Contractual_Requirements.md The 12 requirements (R1.1–R7.1) — this is the spec itself
A4 Internal_Design_Review_Checklist.md 62-item checklist — your carry-in to design review
A5 Diagram_SoC.md Full SoC block decomposition, NoC erasures (N-1–N-5)
A6 Diagram_Chiplet.md Chiplet topologies, D2D interfaces, interposer types
A7 Memory_Controller_Checklist.md 55-item controller checklist, 8 failure modes (MC-1–MC-8)
A8 DIMM_Module_Checklist.md 38-item DIMM checklist, 5 failure modes (FM-1–FM-5)
A9 Board_Level_Alignment.md 4 preservation rules, board failure modes, 27-item checklist
A10 Engineering_Rationale.md Why the spec exists — historical precedents, cost argument
A11 Non_Claims.md What the spec explicitly does not do (NC-1–NC-10)
A12 Memory_Alignment_Spec.md 8-tier memory hierarchy, structural events (ME-1–ME-7)

After A12: Read Glossary_Extensions.md for term definitions, FAQ.md for edge cases, Adoption_Roadmap.md for where the spec goes next.


Path B — Computer Science / Software Engineering#

You already know: Systems programming, OS internals, debugging, telemetry, APIs. You will recognize: The metadata-as-separate-channel pattern, the "optional by default" constraint, the TCP/IP parallel. Your instinct: "What is the abstraction, and where does it sit in the stack?"

Reading Sequence#

Step File Why This Order
B1 README.md Module overview, building metaphor, structural orientation
B2 FAQ.md 40+ questions — fastest way to build a mental model
B3 Spec_Overview.md Executive-level summary — the whole spec in one file
B4 Engineering_Rationale.md The "why" — TCP/IP parallel, DFT comparison, cost argument
B5 Non_Claims.md What the spec does not claim — boundaries and silence
B6 Contractual_Requirements.md The 12 requirements — now you have context for them
B7 Diagram_SoC.md SoC internals — how the metadata layer relates to function
B8 Board_Level_Alignment.md How metadata survives board-level integration
B9 Memory_Alignment_Spec.md Memory hierarchy as a persistence problem
B10 Diagram_Chiplet.md Multi-die topologies — distributed metadata challenge

After B10: Read Glossary_Extensions.md for term alignment, Adoption_Roadmap.md for ecosystem context, Internal_Design_Review_Checklist.md if you want to see the hardware engineering side.


Path C — Physics / Applied Science#

You already know: Measurement theory, observability, conservation principles, signal integrity. You will recognize: The "observation without interference" constraint, the isolation requirement, the monotonic time axiom. Your instinct: "What is actually being preserved, and why does it matter structurally?"

Reading Sequence#

Step File Why This Order
C1 README.md Module overview, building metaphor, structural orientation
C2 Spec_Overview.md Executive-level summary — the observability frame
C3 Engineering_Rationale.md Structural reasoning — why observability is designed in
C4 Non_Claims.md Explicit boundaries — what the spec leaves silent
C5 Contractual_Requirements.md The 12 requirements — observe the isolation axioms
C6 Memory_Alignment_Spec.md Memory as a persistence hierarchy — 8 tiers, volatility line
C7 Diagram_SoC.md SoC as a system — where structural information is created and lost
C8 Memory_Controller_Checklist.md Controller as structural bottleneck — 8 failure modes
C9 FAQ.md Edge cases and conceptual clarifications
C10 Adoption_Roadmap.md How a structural reservation becomes infrastructure

After C10: Read Diagram_Chiplet.md for multi-die structural challenges, Board_Level_Alignment.md for preservation rules at the board boundary, Glossary_Extensions.md for precise term definitions.


Path D — Interdisciplinary / New to All of It#

You already know: You are curious. That is enough. You will recognize: Clear writing, honest framing, and a specification that respects your time. Your instinct: "Start at the beginning and explain things as they come."

Reading Sequence#

Step File Why This Order
D1 README.md Start here — the building metaphor makes everything concrete
D2 FAQ.md §12 Student Questions section — the 7 most common questions
D3 Spec_Overview.md The whole module summarized in one file
D4 Glossary_Extensions.md 70+ terms defined — keep this open as a reference
D5 FAQ.md (full) All 40+ questions — build understanding through Q&A
D6 Engineering_Rationale.md The "why" — real-world failures that motivate the spec
D7 Non_Claims.md What the spec refuses to claim — this builds trust
D8 Contractual_Requirements.md The actual spec — 12 requirements, now in context
D9 Adoption_Roadmap.md Where all of this is going — and where students fit
D10 Diagram_SoC.md Visual architecture — take it slow, use the glossary

After D10: Explore any file that interests you. Every file stands alone. Use Session_Context.md §7 for the module's own recommended reading order.


5 — Depth Levels#

Each path above can be traversed at three depths. The depth determines how much of each file you engage with.

Level 1 — Newcomer#

Time commitment: 1–2 hours across the module. Strategy: Read only the first 3–4 files in your path. Focus on the Session Context table, the opening sections, and the ASCII diagrams. Skip checklists and numbered identifier series on the first pass.

What you should be able to explain after Level 1:

  • What the D369 module is (a structural observability reservation for silicon)
  • What the three tags are (Source ID, Lifecycle State, Monotonic Time)
  • What the building metaphor means (empty conduit, not pulled wire)
  • Why the specification does not define behavior
  • Why fabs come before students in the adoption order

Level 2 — Intermediate#

Time commitment: 3–5 hours across the module. Strategy: Complete your full path (all 10–12 files). Read the numbered identifier series (R1.1–R7.1, ER-1–ER-10, NC-1–NC-10). Review the checklists at a conceptual level — understand what each section checks for, not every individual item.

What you should be able to explain after Level 2:

  • Everything from Level 1, plus:
  • The four structural rules (isolation, no dependence, no modification, contractual removal)
  • The three-page contract structure (requirements → rationale → non-claims)
  • At least three failure modes from any checklist (DIMM, controller, or NoC)
  • The difference between debug infrastructure and structural metadata
  • Why the specification uses silence as a structural tool (S-1–S-3)
  • How memory tiers relate to metadata persistence

Level 3 — Advanced#

Time commitment: 6–10 hours across the module (including cross-referencing). Strategy: Read every file. Follow the cross-references. Trace identifiers across files (e.g., how R1.1 maps through the design review checklist, how MC-1 relates to the memory tier model). Read Meta.md and Session_Context.md to understand the module's own structural grammar.

What you should be able to explain after Level 3:

  • Everything from Levels 1 and 2, plus:
  • How all 76 numbered identifiers relate to each other
  • The full checklist cascade (182 items across 4 checklists) and what each section protects
  • The chiplet-specific challenges (D2D erasure, interposer types, HBM problem)
  • The board-level preservation rules and their failure modes
  • The adoption roadmap phases and why the ordering matters
  • How the D369 module connects to the broader RTT spine
  • Why the Anti-Inflation Principle governs the specification's claim surface

6 — Milestone Markers#

These markers are reference points, not grades. They describe what understanding looks like at each stage.

  LEVEL 1                    LEVEL 2                    LEVEL 3
  Newcomer                   Intermediate               Advanced
  ─────────────────────────────────────────────────────────────────

  ☐ Three tags               ☐ 12 requirements          ☐ 76 identifiers
  ☐ Building metaphor        ☐ Four structural rules     ☐ 182 checklist items
  ☐ "Not behavior"           ☐ Three-page contract       ☐ Chiplet topologies
  ☐ Fabs before students     ☐ Failure modes (any 3)     ☐ Board preservation rules
  ☐ No RTT required          ☐ Debug vs. metadata        ☐ Adoption phases (all 6)
                              ☐ Silence as structure      ☐ Cross-module spine
                              ☐ Memory tiers              ☐ Anti-Inflation Principle

A student who reaches all Level 1 markers understands the module's intent. A student who reaches all Level 2 markers understands the module's structure. A student who reaches all Level 3 markers understands the module's architecture.

None of these levels require RTT knowledge. The module is self-contained.


7 — Where Students Enter the Adoption Timeline#

The Adoption Roadmap (Adoption_Roadmap.md) defines six phases:

  Phase 1        Phase 2        Phase 3         Phase 4          Phase 5         Phase 6
  Spec           Fab            Silicon          Ecosystem        Adoption        Cross-
  Freeze         Engage         Reservation      Seeding          Wave            Domain
  ═══════════════════════════════════════════════════════════════════════════════════════
                                                  ▲
                                                  │
                                            Students arrive
                                                here

Students arrive at Phase 4 — Ecosystem Seeding. Not before.

This ordering is deliberate:

"Fabs before students."

If students arrive first, the specification looks academic — an interesting idea without substrate. If fabs arrive first, the specification looks inevitable — silicon already supports it, and students simply learn what is there.

This is how CUDA won. This is how POSIX won. This is how TCP/IP won. The infrastructure came first. The education followed the infrastructure.

What this means for you as a student: You are reading a specification that is designed to exist in silicon before it exists in classrooms. The module does not need you to advocate for it. It needs you to understand it clearly enough that when the silicon arrives, you can use it.


8 — Reading the Module as a Whole#

For students who want to understand the module's internal structure — not just the content, but how the files relate to each other — two files serve as structural maps:

  • Session_Context.md — The module's structural handshake. Section 7 contains the module's own 10-file recommended reading order. Section 6 defines anti-patterns. Section 10 provides AI agent quick-reference rules.

  • Meta.md — The module's manifest. Contains the full 17-file table with roles, status, and purpose. Contains the dependency graph, the numbered reference system (all 76 IDs), and the checklist inventory (all 182 items).

Together, these two files let you see the module the way the module sees itself.

9 — What This File Is Not#

This file is NOT Because
A curriculum It does not define learning objectives or assessments
A syllabus It does not assign readings to dates or sessions
A certification It does not test, grade, or credential
A textbook It does not teach chip design or RTT
A prerequisite list The module has no prerequisites (FAQ Q10.2)
A pedagogy mandate NC-6 excludes analytics; this extends to instructional design
A promise of learning outcomes NC-8 excludes performance improvement claims
A dependency on external material Every file in the module stands alone

This file is a map. It shows you where the trails are. You choose which one to walk and how far to go.


10 — For Educators#

If you are using the D369 module in a classroom, lab, or study group:

Use the paths as starting templates. Adjust them for your students' backgrounds. The paths are suggestions, not prescriptions.

Use the milestone markers as discussion prompts. "Can you explain the three tags?" is a better classroom question than "Did you read the file?"

Use the FAQ as a Socratic resource. The 40+ questions in FAQ.md are designed to surface the most common confusions. Many of them work directly as discussion starters.

Do not promise outcomes the specification does not promise. The D369 module is explicit about its non-claims (NC-1–NC-10). Classroom framing should respect those boundaries.

Do not require RTT as a prerequisite. The module was designed to be self-contained. Requiring RTT knowledge before entering the module contradicts the module's own design.

  └──────────────────────────────────────────────────────────┘

The D369 module sits between foundational operator definitions (RTT/1) and applied substrate modules. Students entering through D369 are entering the RTT spine at the silicon layer — the point where abstract structural grammar meets physical substrate.


13 — The One Sentence to Remember#

"Nothing here tells us what to build — only what not to erase."

If you remember that sentence, you understand the specification. Everything else is detail, precision, and engineering rigor built around that single idea.
