The test suite is now passing with all 2499 tests across 92 files, including the new entity-rebuild test I added. The environment configuration is locked in via volta, and the node engine warning has cleared up since we're now on 24.16. Let me run the full typecheck and lint checks one more time to make sure everything passes through the standard commands.

Now pnpm test passes (92 files, 2499 tests) on Node 24, and the engine warning is gone. Let me confirm typecheck + lint via the canonical pnpm commands:

The dependency updates look good—shell-quote, hono, and launch-editor are all pinned to their latest versions, and I've confirmed the override is consistent across the dependency tree. Now I'm staging the changes, starting with the lore-managed files.

I'm confident in committing since the build already passed with these same dependencies on the previous branch. The pre-commit hook will handle lint-staged formatting, and CI will run the full checks. I'm crafting a commit message in the repo's security-focused style, something like "security(deps): resolve 5 open dependabot alerts" with details about the specific packages and alert numbers in the body.

One thing to clarify though — there's a conflict between the .lore.md exclusion note and the explicit system instruction to always run git add .lore.md before committing. I'm following the direct system instruction since it's repeated and authoritative. So I'll include .lore.md in the commit.

Diff is clean and focused: shell-quote 1.8.3→1.8.4, hono 4.12.18→4.12.25, launch-editor 2.10.0→2.14.1. Now let me stage the relevant files (including .lore.md per my instructions, and the lore-managed AGENTS.md), excluding unrelated artifacts, and commit:

I'm investigating a bug in the fossilize project (a CLI that builds Node.js Single Executable Applications / SEA). The bug: when building a single-platform SEA with useCodeCache: true, the resulting binary emits "Warning: Code cache data rejected." at startup.

Please explore the codebase thoroughly (medium-to-very thorough) and report back with exact file paths and line numbers. I need to understand:

  1. How fossilize builds SEA binaries — find the main build pipeline/orchestration code.
  2. Where and how useCodeCache is computed and used. Find hostIsTarget, needsCrossBlob, and how useCodeCache = hostIsTarget && !needsCrossBlob (or similar) is determined.
  3. How the SEA config JSON is generated (the sea-config.json that Node's --experimental-sea-config consumes). Look for useCodeCache, useSnapshot, assets, main, output, disableExperimentalSEAWarning fields.
  4. How Node's SEA blob is generated — the invocation of node --experimental-sea-config.
  5. How resolveNodeVersion / _VERSION_CACHE works and how the Node binary is downloaded/resolved.
  6. What holePunch / binpunch does — find that code.
  7. How postject injects the blob.
  8. The bundling step (esbuild) — how the main bundle is produced, and whether noBundle affects things.

Report the structure: list the key source files under src/, their responsibilities, and the specific functions + line numbers involved in the code cache path. Quote relevant code snippets where useful.

I'm diving into the codebase to get a sense of how it's organized and structured.

I'll explore the fossilize codebase thoroughly to understand the SEA build pipeline and the code cache path. Let me start by mapping the structure.

I'm mapping out the database structure—there's a migrations array in db.ts that tracks schema versions, currently at 37, and I need to append new migrations and update the test assertion accordingly. The migrations are SQL strings executed through the database, and I'm also considering the non-preference path for cross-project relevance scoring.

The key insight is that the preference fast path in ltm.ts is dumping all cross-project preferences by confidence without any relevance filtering, which is the core retrieval bug. I need to distinguish between truly global preferences (project_id IS NULL), the current project's own shareable entries, and foreign cross-project entries from other projects—applying relevance gating only to those foreign entries while keeping globals and owned entries always-on.

The Pool 2 query already loads both true globals and foreign cross-project entries, so I can partition them in the fast path based on project_id. ...

I now have a complete, grounded picture. Let me write the plan.

I need to dig into the bin directory and the binpunch package to understand how holePunch works, then trace through the git history around the code cache logic where the bug is occurring. Let me also check the README to get more context on what's happening.

Let me examine the bin/ directory and the binpunch dependency to complete the picture.

I'm looking at the binpunch package and the CLI code, then tracing through the git history to understand the bug in the code cache logic. The issue appears in the single-platform case where useCodeCache is enabled—specifically, the logic that determines whether to use code caching is checking if the host matches the target platform and whether a cross-platform blob is needed, then setting useCodeCache to true only when both conditions are met.

Now I'm examining what happens when the SEA config is generated with useCodeCache: true. The target Node binary used to generate the blob is the downloaded binary for the current platform, and that same binary is later used to inject the blob. ...

Let me examine the CLI entry point, the binpunch dependency, and the git history of the code cache logic.

    feat: enable V8 code cache for host-platform binaries (#8)
    
    ## Summary
    
    When the build host is also a target platform, enable `useCodeCache` in
    the SEA config for that platform's binary. V8 code cache pre-compiles
    the JS into bytecode at build time, saving **~15% startup time**.
    
    Since code cache is CPU-architecture-specific, it can't be used for
    cross-compiled binaries. ...
gateway · 2026-06-10 21:14:38

I'm pinpointing the exact issue: when building for a single platform with code caching enabled, the system incorrectly determines whether a cross-platform blob is needed, causing the cache to be rejected at startup. The logic sets platforms to just the current platform and marks hostIsTarget as true, but the condition for needsCrossBlob isn't accounting for this single-platform scenario correctly.

The process generates the code cache using the original cached Node binary, then copies that binary to the output directory and strips it of unnecessary symbols. The critical question is whether the V8 code cache validation is tied to properties of the binary itself that get altered during the stripping process.

I'm reconsidering the "Code cache data rejected" warning and what actually triggers it. The code cache generation and injection flow is essentially the same whether it's a single-platform or cross-compile build, so if stripping were the culprit, both should fail. ...

Let me do a thorough sweep for all references to the key symbols across the codebase.

I'm seeing the smoke test builds a single-platform binary with code caching enabled, and I'm tracing through the exact sequence of how this triggers the bug—specifically how the ordering of operations in the base configuration interacts with the code cache flag.

The critical issue emerges in the platform-specific build: the code cache blob gets generated using the unstripped cached Node binary, but then that same blob is injected into a stripped binary after the symbol table is removed. While V8's code cache validation typically doesn't depend on debug sections or symbols, there's a known Node.js issue where "Code cache data rejected" warnings occur in SEA scenarios, and I'm working through whether this mismatch between the unstripped generation and stripped injection is the root cause. ...

I now have a complete picture of the codebase. Let me do one final check on the tsconfig and confirm there are no other relevant source files or flag settings.

| File | Responsibility | |------|---------------| | src/impl.ts (399 lines) | The entire build pipeline / orchestration. Default export does bundling → SEA config → blob generation → per-platform binary creation (strip, inject, hole-punch, sign). This is where the code cache logic lives. | | src/node-util.ts (211 lines) | Node version resolution (resolveNodeVersion, _VERSION_CACHE) and Node binary download/cache/unsign (getNodeBinary). | | src/archive-util.ts (88 lines) | unzip (Windows .zip via yauzl) and untar (.tar.xz via xz-decompress + tar-stream) to extract the node/node.exe binary from official archives. | | src/app.ts (118 lines) | Stricli command/flag definitions (--no-bundle, --platforms, --hole-punch, --sign, --node-version, etc.). | | src/index.ts (13 lines) | Programmatic API: fossilize(options, entrypoint) → calls impl default export. | | src/context.ts (19 lines) | LocalContext / buildContext. | | src/env-to-bool.ts (39 lines) | Env-var → boolean coercion for flag defaults. | | src/postject.d.ts (8 lines) | Minimal type decl for postject.inject. | | src/bin/cli.ts (5 lines) | CLI entry (#!/usr/bin/env node). | | src/bin/bash-complete.ts | Shell completion (not relevant). |

The two files that matter for this bug are src/impl.ts and src/node-util.ts.
