webpack 5 and tsc write "sourceRoot": "" for map-relative sources. Since
5f702dd6c the shared join added "/" for any non-null root, so these
sources resolved from the URL root: rxjs's ../../../src/internal/Observable.ts
under /npm/rxjs@7.8.1/dist/cjs/internal/ became /src/internal/Observable.ts,
and xterm's webpack://xterm/./src/... became https://host/webpack://xterm/....
Treat an empty root like a null root in sourceMapReference, the single join
used by trace-web-source-location, analyze-javascript-application and the
web source-map fetcher. Chrome, Firefox and trace-mapping skip an empty root,
and tc39/ecma426#183 wrote the current steps to match them. Non-empty roots,
including "/" and repeated slashes (#6726), keep their existing behavior.

Resolve the filesystem-selected manifest parent once before deriving script paths and reuse the shared containment rule. Preserve selected manifest spelling and capture metadata while retaining source integrity, symlink refusal and cleanup. Cover differing and identical lexical siblings through both artifact consumers and public CLI/MCP parity.
Share embedded-map version admission and derive indexed overlap from represented mappings. Carry createRequire filename bases through worker facts and graph identity. Select factory export bindings at each bundler owner.
Validated accepted and malformed source maps through real CLI and stdio MCP codec workflows; verified loader and esbuild graph output against Node runtime controls. Rebased consumer checks passed.

Supply the system root and temporary directory in isolated Windows CLI environments, while preserving explicit caller overrides. Include captured command output in web acceptance exit-code failures so startup and codec errors remain diagnosable.
* fix(bun): report the real runtime and enforce worker memory budgets on Windows
Under Bun, REA recorded Node/V8 identity it did not observe and its JavaScript helper processes ran without a memory bound, because Bun ignores the V8 heap flags REA passes. Source-map trace Evidence claimed runtime node-v8 with Bun's synthetic V8 heap limit (the decoder then rejected that limit, so trace_web_source_location always failed), analysis resource failures reported heap limits Bun does not enforce, the HAR decoder claimed a fixed 192 MiB heap, and doctor reported Bun's Node.js compatibility version as the Node version.
Identify the runtime once from process.versions. Source-map reports record id bun with the Bun and Node.js compatibility versions and a null v8_heap_limit_bytes; the decoder checks the heap budget only for V8 reports and rejects a report from a runtime other than the launching one. The analysis worker reports a null heap limit under Bun, HAR limitations and failures omit heap sizes under Bun, and the doctor node check reports Bun and passes when its Node.js compatibility version is supported.
On Windows under Bun, each helper's owned Job Object now carries a commit limit of its heap budget plus a measured 512 MiB Bun runtime reserve (704 MiB for the codec and HAR decoder, 1536 MiB for the default analyzer). The native addon accepts an optional page-aligned job memory limit on process_spawn, verifies it by readback, associates a private completion port before the child is created, and reports a sticky memoryLimitReached and peak job commit on each poll; inspect reports jobMemoryLimit. A requested limit with an artifact lacking the control refuses the launch, and non-Windows launchers refuse a limit.
Reaching the limit is classified by the job notification rather than Bun's exit status: the analyzer fails the current source with a memory resource failure reporting worker_process_memory_limit_bytes, the codec returns a memory resource failure, and the HAR decoder returns its memory failure with process_memory_limit_bytes. Bun source-map Evidence records process_memory_limit_bytes, verified against the launcher. Node.js launches and outputs are unchanged.
* fix(windows): drain memory notifications after observing exit

Deliver complete Evidence directly through MCP with required nullable analysis profiles and immutable per-server delivery settings. Bind selected environments at construction and require typed cleanup outcomes with retained retry ownership.
Remove test-only routing, duplicate session and snapshot metadata, producer-field repairs, and ambiguous provider arguments. Separate artifact byte identity from occurrence classification and retain typed source-map and partial native facts across CLI, MCP, and verifier consumers.
BREAKING CHANGE: obsolete Evidence envelopes, session aliases, incomplete snapshots, and missing normalized producer facts are no longer accepted.
