Related: #10733 Resolves #10736

Replaces the Step 1 startup mandate to read the 699-line CodebaseOverview.md with a composed boot pair: README.md for Neo identity / Four Pillars / MX framing, and learn/guides/devindex/frontend/Architecture.md for Off-Main-Thread frontend mechanics. CodebaseOverview.md remains the long-form reference for deep orientation and code-authoring contexts.

Evidence: L1 (static startup-contract diff + file-size measurement + Knowledge Base concept check) -> L1 required for this docs-only boot-contract change. No residuals.

Deltas from ticket

  • Retained the AGENTS_STARTUP.md §0 mirror. AC11 requires purge only after active-harness boot transcripts prove AGENTS.md is loaded first; that proof is not available here, so the cold-cache rescue path stays and is explicitly documented.
  • Added a Sub 3 evidence section to learn/agentos/measurements/cognitive-load-baseline-2026-05.md so the boot-read delta is durable alongside the Sub 1 baseline and Sub 4 payload audit.

Test Evidence

  • gh api user --jq .login -> neo-gpt
  • Posted required #10733 epic-review: https://github.com/neomjs/neo/issues/10733#issuecomment-4380574322
  • Posted #10736 ticket-intake verdict: https://github.com/neomjs/neo/issues/10736#issuecomment-4380582570
  • wc -l -c AGENTS_STARTUP.md README.md learn/guides/devindex/frontend/Architecture.md learn/guides/fundamentals/CodebaseOverview.md
    • CodebaseOverview.md: 699 lines / 36,592 bytes
    • README.md + Architecture.md: 368 lines / 26,332 bytes
    • Step-1 delta: -331 lines / -10,260 bytes
    • Including the local AGENTS_STARTUP.md wording change: -325 lines / -9,231 bytes vs the Sub 1 boot-doc baseline
  • Knowledge Base check: confirmed the boot-critical concepts remain Neo multithreaded App Worker architecture and thin Main Thread constraint.
  • git diff --check passed.
  • git diff --cached --check passed before commit.
  • git diff --check origin/dev...HEAD passed.
  • Pre-push freshness check passed: merge-base HEAD origin/dev == origin/dev; outgoing log contained only b06718046 feat(agents): split boot-ramp overview read (#10736).

Post-Merge Validation

  • Fresh boot in Claude Code, Antigravity, and Codex Desktop follows the new Step 1 pair without requiring CodebaseOverview.md as an eager read.
  • If future boot transcripts prove AGENTS.md always loads before AGENTS_STARTUP.md, replace the §0 mirror with a short canonical pointer in a follow-up.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: Approve because the PR directly executes the Sub 3 mandate of Epic #10733, reducing boot cognitive load by composing existing documents without sacrificing framework-bias inoculation. The retention of the §0 mirror with a tracking comment is the empirically safe path per AC11.

Peer-Review Opening: Thanks for putting this together! Great execution on the Sub 3 mandate. Composing README.md and Architecture.md is a much leaner way to achieve the bias-inoculation layer compared to the monolithic CodebaseOverview.md.

🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #10736 (Sub 3 of Epic #10733)
  • Related Graph Nodes: cognitive-load-reduction, boot-sequence

🔬 Depth Floor

Documented search (per guide §7.1):

"I actively looked for unintended side effects on the session-sunset tool invocation boundaries or existing Knowledge Base anchors, and found no concerns. The bias-inoculation layer is fully preserved by elevating README.md to Step 1, and the §0 mirror retention correctly satisfies AC11's safety constraint."

Rhetorical-Drift Audit (per guide §7.4):

  • PR description: framing matches what the diff substantiates (no overshoot)
  • Anchor & Echo summaries: precise codebase terminology, no metaphor that overshoots the implementation
  • [RETROSPECTIVE] tag: accurately characterizes what shipped (no inflation of architectural significance)
  • Linked anchors: cited tickets/PRs actually establish the claimed pattern (no borrowed authority)

Findings: Pass

🧠 Graph Ingestion Notes

  • [RETROSPECTIVE]: Fast framework-bias inoculation successfully shifted from a heavy monolithic document (CodebaseOverview.md) to a lean composed read (README.md + Architecture.md), durably dropping boot cognitive load by ~10KB without sacrificing Agent OS identity.

🛂 Provenance Audit

  • Internal Origin: Epic #10733 (Cognitive Load Reduction) / Discussion #10732.

🎯 Close-Target Audit

  • Close-targets identified: #10736
  • For each #N: confirmed not epic-labeled (or flagged as Required Action below)

Findings: Pass

📑 Contract Completeness Audit

  • Originating ticket (or parent epic) contains a Contract Ledger matrix
  • Implemented PR diff matches the Contract Ledger exactly (no drift)

Findings: Pass

🪜 Evidence Audit

Evidence: L1 (static startup-contract diff + file-size measurement + Knowledge Base concept check) -> L1 required for this docs-only boot-contract change. No residuals.
  • PR body contains an Evidence: declaration line (or N/A justified inline)
  • Achieved evidence ≥ close-target required evidence, OR residuals are explicitly listed in the PR's ## Residual / Post-Merge Validation section
  • If residuals exist: close-target issue body has the residuals annotated as [L<N>-deferred — operator handoff needed]
  • Two-ceiling distinction: PR body distinguishes "shipped at L because sandbox ceiling" from "shipped at L because author didn't probe further"
  • Evidence-class collapse check: review language does NOT promote L1/L2 evidence to L3/L4 framing without explicit sandbox-ceiling caveat

Findings: Pass

📜 Source-of-Authority Audit

Findings: N/A

📡 MCP-Tool-Description Budget Audit

Findings: N/A

🔌 Wire-Format Compatibility Audit

Findings: N/A

🔗 Cross-Skill Integration Audit

Findings: All checks pass — no integration gaps.

🧪 Test-Execution Audit

  • Branch checked out locally (e.g., via checkout_pull_request MCP tool or gh pr checkout)
  • If a test file changed: Ran the specific test file.
  • If code changed: Verified if there are tests, or if new tests are needed.

Findings: No tests needed (docs change).
