+Public declarations carry their required standard-library dependencies. Runtime's emitted declaration preserves a narrow `esnext.disposable` reference so strict ES2022 consumers can import it without a broad ESNext override or `skipLibCheck`. The check of the packed consumer in `scripts/check-packed-disposable.sh` covers all five public entrypoints, explicit disposal typing, and installed close/dispose lifecycle behavior in Docker.

+# Strict installed ES2022 disposable declarations: issue 981
+
+Source base 5c82ba6ca168d07b743fac5c6adbf38822ae0302 is the reviewed locked-audit prerequisite. Runtime, public entrypoints and compiler configuration are byte-identical to main/v20.0.0 ceb58e656ec5bc85f0ae5991bf2a55599693bbb3; no disposal fix exists. The initial probe independently installs the actual packed artifact and reproduces TS2550 at emitted Runtime.d.ts:30 with TypeScript 5.9.3, strict NodeNext/ES2022, skipLibCheck=false, explicit ES2022/DOM/DOM.Iterable, types=[] and no source aliases.
+
+The full matrix repeats with committed portable fixtures: root-close, root-dispose and combined root/advanced fail. Root-dispose additionally fails the consumer symbol access. Advanced-only and explicit ESNext.Disposable controls pass. This isolates the missing narrow declaration dependency rather than a general module-resolution failure. Package payload gates pass 746177 compressed / 3257290 unpacked / 971 entries within unchanged 760000 / 3300000 / 1050 limits. No GREEN or source repair is claimed.
+
+All execution is COPY-based Docker under the existing git-warp-tests worker/image/build volume and only its concrete resource reservation. Build 20 GiB is monitored, not quota-backed; runtime 3 GiB tmpfs remains within 4 GiB; logs 128 MiB with 16 MiB phase / 96 MiB generated nonobject; 4 CPU / 8 GiB / pids 768 and host / VM 50 GiB floors/timeouts/child cleanup remain active. Matrix peak 50536448 runtime bytes, 50917376 generated nonobject, 1960185856 build, 27 tasks; no guard/OOM/PID refusal. Worker stops before lease release. Raw and normalized/archive hashes retain exact scopes. Mainline merging remains paused.
+
+## Reviewed narrow repair and GREEN
+
+Agy approves the one preserved narrow esnext.disposable reference at Runtime's public declaration boundary. Complete original/artifacts/qualification are delivered intact to Reader under receipt e645ff44-1a8a-423f-a8e9-5f9ce8a51716 and posted on 981 before implementation. Unsupported estimates, consumer compiler floor and reviewer authorization language remain qualified; the user already authorizes implementation and PR preparation. Private WarpStorage declarations are pruned and need no new public reference.
+
+The only production change is the top-of-file preserved reference in Runtime.ts. It adds a standard declaration dependency and no runtime statements. Disposable-green-981-v3 passes source/test types, explicit source/fixture lint without ignored-file warning, all 8 strict installed compiler cases and 3 native lifecycle cases. Root close / direct dispose / combined/advanced/testing/diagnostics/charts/explicit-narrow-library cases pass with TypeScript 5.9.3, no source aliases, types=[], ES2022 and skipLibCheck=false. Installed close, repeated dispose, concurrent close / dispose and closed-runtime refusal retain behavior. Actual payload 746269 compressed / 3257406 unpacked / 971 entries passes unchanged limits.
+
+Runtime-parity-981-v2 independently strips only the reference prefix in the copied guest source, re-emits the baseline to owned bounded output, and compares generated JavaScript after removing the single new comment. Bytes match exactly. Baseline JS SHA256 b54207d16ecb141d9e79b3785f6561363fc5779f04434439fc86002d3385b3d9; candidate 532e9cd708bc36a84ec4987d7c0ee3831f3078d6a959b19a87dc8eaaa8902716. The differing bytes are the comment, not a hidden runtime change. This identified comparison command is not a claim that its guest source stayed unchanged.
+
+Earlier attempts remain qualified: GREEN v1 passes 8 compiler cases but fails missing container rg; v2 passes compile / lifecycle but explicitly surfaces an ignored-fixture lint warning; parity v1 refuses at fixture console/no-undef before comparison. The fixture imports Node stdout and v3 / parity v2 verify actual lint cleanly. No threshold, skipLibCheck, engine floor, symbol identity, global configuration or runtime behavior is weakened. This type-only annotation is not a runtime refactor; SSJS is green with no new domain model, boundary leakage, ambient time / entropy or trust casts. Full required project gates, final-head independent review and hosted validation remain open. Mainline merging stays paused.
