This is the 0.64 index-store cutover. Text search, the call graph and meaning search move to one index store per repository, shared by its worktrees and clones; the old trigram index, SQLite call-graph store and content-addressed views are deleted (about 215,000 lines net).

What changes for users

• Each repository builds its new indexes once on first use: text in about a second, the call graph in under a minute for large projects. Worktrees of one repository share them, and a new worktree starts from a sibling's indexes and processes only the files that differ.
• Meaning search reuses old vectors for unchanged files embedded with the same model.
• Old index folders stay on disk; npx @cortexkit/aft cache prune-legacy lists and removes them.
• views.enabled, views.callgraph_copies and worktree.ram_overlay show a removal notice; views.idle_checkout_hours becomes idle.checkout_hours. Config names retired in 0.62 or earlier are refused in user config and load with a notice in project config.
• trace_to and impact label each root (main, test, attribute, public API, no caller found).

Measured on AFT's own repository (7,300 files)
Call-graph build 207 s to 17 s; index disk 1.7 GB to 0.3 GB; typical edit catch-up 4.7 s to 0.1 s; dead code first run 72 s / +4.25 GB to 6-8 s / +0.8 GB; an edited worktree's call graph median 3 MiB between publications; a new worktree at the same commit under a second instead of about 160 CPU-seconds.

Verification

• Full Rust suite on Linux: all pass except the 12 native-secret-shell tests and one rust-analyzer test the build server can't run (both fail the same way on main).
• Incremental call graph equals a cold build after each of 430 real edits (edit, reuse, extract and checkout gates).
• Dead-code findings unchanged across a 91-project corpus; search-quality benchmark rows byte-identical except five declared pattern-lane candidate counts (land-index-store-0.64.json).
• macOS and Windows compile with warnings as errors.

The release notes are in review; the version bump and tag follow through scripts/release.sh after this merges.

Summary by cubic

This is the 0.64 index-store cutover: text search, the call graph and meaning search move to one index store per repository, shared by its worktrees and clones; the old trigram index, SQLite call-graph store and content-addressed views are deleted (about 215,000 lines net).

What changes for users

• Each repository builds its new indexes once on first use; worktrees share them, and a new worktree starts from a sibling's indexes and processes only the files that differ.
• Meaning search reuses stored vectors for unchanged files embedded with the same model, and a repository is filled by one process at a time so no chunk is embedded twice.
• Editing a config file (Cargo.toml, tsconfig.json) rebinds only the files it changed, not every file that reads any config.
• A repository whose index-store files a newer build wrote is refused with storage_requires_newer_reader, naming the file and version, instead of being rebuilt over them.
• Old index folders stay on disk; npx @cortexkit/aft cache prune-legacy lists and removes them.
• views.enabled, views.callgraph_copies and worktree.ram_overlay show a removal notice; views.idle_checkout_hours becomes idle.checkout_hours, and config names retired in 0.62 or earlier are refused in user config.
• trace_to and impact label each root: main, test, attribute, public API, or no caller found.

Measured and verified

• On AFT's own repository (7,300 files): call-graph build 207 s to 17 s, index disk 1.7 GB to 0.3 GB, typical edit catch-up 4.7 s to 0.1 s, new worktree at the same commit under a second instead of about 160 CPU-seconds, and a busy worktree's call graph holds about a tenth of the memory after a broad edit (about 120 MB instead of 1 GB).
• The store keeps at most 1,024 index files open, so busy daemons stay below macOS's open-file limit.
• Incremental call graph equals a cold build after each of 430 real edits; dead-code findings unchanged across a 91-project corpus; search-quality benchmark rows byte-identical except five declared pattern-lane candidate counts.
• Replaying 6,956 recorded callers/call_tree/trace replies through the new store matches main's corpus except 34 reviewed differences (C++ type-matched method calls and macro-template calls now resolve).
• Full Rust suite passes on Linux except the 12 native-secret-shell tests and one rust-analyzer test the build server can't run (both fail the same way on main); macOS and Windows compile with warnings as errors.
