Native Bun APIs: measure and selectively migrate runtime boundaries (#18)

What to build

A final, independently verified record showing that the chosen set of runtime boundaries works together and that later maintainers can recover every accepted, retained, or inconclusive decision. Users receive a reliable current build and a safe upgrade route; the fork keeps its current upstream-import workflow. All four retained is a valid final result.

Ticket-definition review completed on 2026-10-08: Claude Opus 5.5 agrees this ticket is ready for agent implementation with no remaining blockers. Separate review thread. The completed-work review below remains required after execution.

Acceptance criteria

  • Read the parent and all four completed boundary decisions. Publish a concise decision/evidence table on this ticket, linking the baseline, each boundary's issue/results, accepted production revisions, retained reasons, inconclusive gaps, and separate Opus review threads.
  • Confirm retained/inconclusive candidates left no production adapter/composition refactors behind, and accepted boundaries have one chosen production implementation with comparison variants removed. Attribute every runtime-relevant hunk since the baseline revision to an accepted ticket or a necessary accepted integration correction. Check combined composition keeps the single Effect context, Node contributor tests, unchanged wire/auth/durable formats, and fork web/server/distribution policies using existing focused evidence, not a new generic audit system.
  • If production adapters changed, use the existing integrated source/actual-archive harness to prove combined current-build authenticated transport/Browser, file access, core/plugin recovery/atomicity, controlled process/helper execution, and service lifecycle as affected. Reuse evidence only when Bun pin, lockfile, adapters/consumers/composition, build/packaging inputs, and fixture match the final runtime. If previously separate accepted changes were never verified together, obtain combined parity on all three supported targets; otherwise cite matching integrated evidence and disclose gaps. If nothing changed, cite baseline/retention evidence rather than running redundant suites.
  • If no adapter was accepted, cite the latest matching baseline and run no new performance batches. If the last accepted candidate already included every earlier change with final runtime-relevant inputs, reuse its qualifying batches. Otherwise compare the final build with the same revision's compatibility composition in a disposable checkout, reverting only accepted adapter/composition changes needed for that comparison. Apply the parent's regression gates in two alternating batches of at least five launches per variant/build, at least 60 seconds idle, source/archive separately, and native performance hosts only. Report startup, CPU, RSS/footprint and affected workload/tail/wire metrics as applicable; there is no additional combined benefit threshold.
  • Reproduced combined regression, one-batch-only unresolved regression, missing required combined evidence, or behavior failure blocks completion and shipment of the failing combination. Revert the smallest later-landed interacting adapter when necessary to restore passing behavior, preserve unrelated work/data, and record its final disposition as inconclusive; otherwise obtain the maintainer's concrete follow-up decision. Do not explain away failed gates or mark a failing combination complete.
  • Verify approved runtime breaks have safe first-upgrade, ordinary-update failure/recovery, same-line lifecycle, and manual cross-break recovery evidence. If a break combines with other accepted boundaries, exercise the actual cumulative route once from the pre-program archive to the final archive: clean-stop upgrade, ordinary update that completes or safely restores the running old service, and manual restoration of the pre-program archive over state written by the final build. Use the baseline archive, or the specifically identified installed release in disposable state; otherwise cite matching Evaluate native subprocesses and service lifecycle #23 evidence. No mixed-version IPC bridge is required; current history remains usable.
  • Confirm each accepted adapter passed a genuine baseline/candidate upstream rehearsal with a concise preservation rule. If multiple adapters changed shared files and the latest rehearsal did not already include their combined changes/input, rehearse the pre-program baseline against the final revision with one fixed actual upstream input covering the union of changed shared sites. Otherwise cite matching individual/combined evidence. Apply the parent's conflict-confinement and mechanical preservation criteria; no added recurring repairs, global rewrites, no-op merge evidence, or new sync system. Unresolved combined conflicts block completion.
  • Rewrite the existing runtime-candidates guidance into concise durable decisions: accepted with boundary/preservation rule, retained with reason, or inconclusive with gap and what could resolve it. Link each ticket; do not duplicate benchmark tables or implementation checklists. Add sync-skill preservation text only for accepted adapters. Keep raw artifacts/research outside the repository, with real-data material private/redacted under Baseline and profile native Bun opportunities #19's policy. No new CI workflows/checks/matrices, repo-wide checks, release publication, or sync machinery.
  • Prepare necessary documentation/integration corrections as reviewable repository changes. Commits, push, and any single PR follow the maintainer's actual request and AGENTS.md; create no unsolicited PR or automatic merge/release. PR approval is not invented as a prerequisite for preparing the changes. Keep all edits/comments/labels/state of parent Native Bun APIs: measure and selectively migrate runtime boundaries #18 unchanged: this ticket owns the linked final decision table, and parent closure is the maintainer's action.
  • Have the completed combined evidence and decision record verified by Claude Opus 5.5 in its own fresh separate T3 thread. Resolve blocking findings and link the final agreement before completion; individual reviews are not a substitute for this combined review.

    Program progress: execution started (2026-10-09)

    • All four boundary decisions are complete. Each passed its own fresh Opus 5.5 review:
    • No adapter was accepted. origin/main is still the Baseline and profile native Bun opportunities #19 baseline d5cee2d8fa. Under this ticket's rules, combined parity, performance batches, the cumulative upgrade route and the combined rehearsal are therefore not applicable. The baseline and retention evidence is cited instead.
    • Owning stack layer: native-bun/decision-record, the only layer, based on origin/main. Its only repository change rewrites the runtime-candidates guidance in docs/internals/bun-runtime.md into durable decisions. The layer will be published as a draft PR for review and CI. It will not be merged automatically.
    • Execution worker: delegated task native-bun-24-exec-r1 (Codex GPT-6.1-Sol, high reasoning).

    Status: preparing decision record

    #24 combined verification and durable decisions

    Outcome: no native adapter was accepted. All runtime inputs remain at baseline d5cee2d8faed9d4923af4f59fdfa7e81009c880c / Bun 1.4.2. Repository changes are limited to the durable decisions in docs/internals/bun-runtime.md and the pointer wording in .agents/skills/sync-upstream/SKILL.md. No runtime break or integration correction was needed.

    Decision and evidence table

    Each review below is its own fresh Claude Opus 5.5 / Gilfoyle completed-work review. These individual agreements do not substitute for #24's combined review.

    Boundary Decision and retained reason / inconclusive gap Accepted production revisions Results and immutable evidence Separate completed-work Opus review
    #19 baseline Latest matching source/actual-archive baseline; native macOS arm64, Bun 1.4.2, revision d5cee2d8fa. Five launches per build form; separate diagnostic attribution. Historical provenance and coverage limits remain. None; measurement only Results; gist revision 8cc8a719 mcp:5590e0b2-97bb-4b3e-bde8-04bad293e5bd, round 3 AGREE
    #20 HTTP/WebSockets Retained. Bun 1.4.2 Bun.serve strips supplied Content-Length on streamed bodies, including 206 and raw compressed responses; held-descriptor slices send slice bytes with full-file length. Buffering/pathname reopening cannot preserve the required contract. Explain #20's dedicated/shared compressor wire-byte anomaly first. Reopen when a supported Bun pin fixes both framing defects, using the qualifying test in #20. None Results; gist revision 80249e25 mcp:f9c1c66c-86ce-47e8-ae49-66e3db41f7a1, AGREE
    #21 file operations Inconclusive. Pending callback bounds include worker queueing/scheduling, attachment totals include the out-of-scope retained HTTP platform, FileHandle/promises/media validation coverage is incomplete, and writes are unmeasured. The descriptor-slice failure is a Bun.serve framing defect; held-descriptor range reads outside Bun.serve are untested and a validated-descriptor read candidate must prove them first. Native HTTP file responses remain out of scope while HTTP is retained. Reopen for a reproduced in-scope incompatibility or resolved intrinsic cost, using the qualifying test in #21. None Results; gist revision b6f2580c mcp:29b3a736-6f76-4fb3-9ec2-f9f86eba9d30, round 2 AGREE
    #22 SQLite Retained. node:sqlite and bun:sqlite share SQLite source ID/options on measured macOS arm64 source; even all attributed core-write SQLite work is below the source/archive compatibility ranges, and replay deltas change sign. This is screening evidence from separate runs, not a universal ceiling. Reopen for incompatibility, supported-target engine divergence or actionable binding cost, using the qualifying test in #22. Reports-resolve cannot replace the core-write adoption metric; establish catalog owner policy first. None Results; gist revision 3561fdc9 mcp:4b06e343-8953-45e3-b7c5-17b764f2d5b1, round 2 AGREE
    #23 unit 1: Effect spawner Retained. Bun child_process already spawns natively; all observed Git-status server CPU is below its compatibility wall range in source/archive. Exact spawner share remains unresolved; this does not bound non-CPU waiting or cover active provider turns. Reopen for an in-scope defect or actionable spawner cost, using the qualifying test in #23. None Results; gist revision a548b69b mcp:105d5b0c-5d4e-4016-81bb-d9a8137d3fe3, round 2 AGREE for all three units
    #23 unit 2: login-shell/service-manager reads Inconclusive. Operation-specific latency and parent fraction unmeasured; synchronous elapsed time includes shell/manager execution and waiting. Reopen for an in-scope defect or resolved parent cost, using the qualifying test in #23. None Same #23 results; same immutable gist Same separate #23 review above
    #23 unit 3: launcher server-child spawn Inconclusive. Functional fixtures do not supply launcher spawn/IPC/exit attribution or operation latency. Reopen for an in-scope defect or resolved parent cost, using the qualifying test in #23. Staging/marker operations remain unchanged and separately unmeasured. None Same #23 results; same immutable gist Same separate #23 review above

    Reopening authorizes triage, not adoption. Any future candidate still needs the parent's behavioral, two-batch regression, supported-target and genuine upstream rehearsal gates.

    Runtime-hunk attribution audit

    The baseline audit and publication record establish:

    • origin/main remains d5cee2d8faed9d4923af4f59fdfa7e81009c880c, the Baseline and profile native Bun opportunities #19 baseline.
    • git diff d5cee2d8fa origin/main and git log d5cee2d8fa..origin/main are empty.
    • Changes on native-bun/decision-record since baseline touch only docs/internals/bun-runtime.md and the pointer wording in .agents/skills/sync-upstream/SKILL.md.
    • PR #33 is the only native-bun PR; #30 and #31 are unrelated.

    There are zero runtime-relevant hunks to attribute. No retained/inconclusive candidate left a production adapter or composition refactor. The unchanged tree proves that adapters/consumers/composition, the single bundled Effect context, Node contributor tests, wire/auth/durable formats, helper interpreter/assets, packaging, web/server scope, fork distribution defaults and lightweight CI retain their baseline implementations. This is unchanged-input evidence, not a fresh behavioral pass or a new audit framework.

    Recorded identity checks match #19: installed and pinned Bun 1.4.2; pnpm lock SHA-256 0481f1411a5b808e3434eea352eac2458a3300119ccfc220432c8c2dd9feb4ee; baseline archive 85,231,164 bytes, SHA-256 214c518e79ce84a17b39a03c317e856106db793ee1e9c55c41692cca3982c15e; fixture-manifest SHA-256 2cab401236f6543712a9028154d7a5cdd2992ca78d792498d2c5b9795829b3be. No rebuild, dependency change or fixture mutation occurred.

    Combined gates: not applicable

    • Combined current-build / three-target parity: #24 AC3 says “If nothing changed, cite baseline/retention evidence rather than running redundant suites.” No production adapters changed; matching #19 functional evidence and the boundary retention evidence apply. No new combined suite was run, and absent Linux evidence is not reported as passing.
    • Combined performance batches: #24 AC4 applies its no-accepted-adapter clause: cite the latest matching baseline and run no new batches. Baseline and profile native Bun opportunities #19 remains that baseline. No native speed/CPU/RAM claim is made.
    • Combined regression block: #24 AC5 is not applicable because no adapter was accepted and no combined candidate changed runtime inputs.
    • Cumulative upgrade / ordinary-update failure recovery / manual cross-break recovery: #24 AC6 applies to approved runtime breaks and their combination with accepted boundaries. There are no breaks, removed options, protocol changes or accepted adapters. Historical same-line lifecycle fixtures remain inherited evidence; no new upgrade/recovery proof is required.
    • Combined upstream rehearsal and sync-skill preservation text: #24 AC7–8 apply these to accepted adapters and interacting shared-site changes. There are none. A baseline-versus-identical-runtime rehearsal would be a no-op. No rehearsal or preservation text applies; the sync-skill change only corrects its documentation pointer.

    Explicit remaining gaps

    • The permessage-deflate incompatibility is unowned and unresolved. The retained Bun ws-compat path sends RPC frames to remote/relay/tunnel clients uncompressed. Any separate tracking decision belongs to the maintainer.
    • Linux was never measured. Neither Linux x64 nor arm64 has program source/archive parity or performance evidence. Evaluate native HTTP/WebSockets end to end #20's Linux pull failed before a container ran; later tickets stopped early without new Linux attempts.
    • The dev-runner WebSocket-upgrade timeout remains unresolved. Original and direct-entry source/archive smoke passes do not establish that development path.
    • Baseline initial producer bytes were partly lost, source attribution hashes were inferred rather than prelaunch-attested, and declared warmups were not independently counted. The later archive attribution has prelaunch attestation; it does not repair historical provenance.
    • F1 drained bytes, complete intrinsic file attribution, active provider/workflow performance, operation-specific shell/launcher/staging attribution, full main-archive JPEG/slow-viewer and real remote-client evidence remain absent. Synthetic messages are projection-only and workflow run state is empty.
    • Idle timer attribution, allocation/JSC heap data, effective CPU accounting accuracy beyond nominal Mach tick resolution, sidecar cost and endurance/leak evidence remain unresolved. SQLite engine identity was verified only on macOS arm64 source; no mixed-binding shared-locking inference is made.
    • Bun-independent leftovers: #21 records ServerSecretStore signing-key rereads per media/attachment request (6–9% scheduling-inclusive upper bounds); #22 records catalog.sqlite without owner pragmas and nodeSqliteClient without prepareTransactionControls (~0.94 ms historical upper bound per 100 commits). These remain recorded only in the closed boundary issues.

    Repository change and handoff

    PR #33 merged as 55df74e33b (head c347f6ac2bf1); Check status existing Check passed on c347f6a. It records retained/inconclusive boundary decisions, corrects the descriptor-read limit, links the qualifying reopen tests and restores the PR #15 migration evidence; the sync-skill edit changes pointer wording only.

    Combined Opus review link/verdict: fresh Claude Opus 5.5 / Gilfoyle combined review thread mcp:141416bf-3e73-4664-8082-9f0449a86f00 . Round 1 required three fixes (a #21 overstatement, undefined workload labels and checklist length, a stale handoff section). Round 2 verdict: VERDICT: AGREE — all #24 acceptance criteria satisfied (combined record verified)

    Status: landed in PR #33 (merge 55df74e33b). Non-blocking follow-ups the combined reviewer noted and left out of this PR:

    • docs/internals/effect-services.md:101 still calls the runtime doc a list of "native Bun candidates".
    • bun-runtime.md could restate why RPC frames are uncompressed: Bun's ws compatibility path ignores the perMessageDeflate requested at server.ts:260.
    • Line wrapping in the rewritten section is uneven.
