+# Task: Integrate Learning download size removal
+
+## Identity
+
+- Task ID: 20260820-integrate-download-size-6e3a91c2
+- Mode: Integration
+- Branch: codex/20260820-integrate-download-size-6e3a91c2-integrate-download-size
+- Worktree: D:\Datas\OthersProjects\makelore-integrate-download-size-6e3a91c2
+- Base commit: 2168e291b2bf8ac8690c482f56400554a8d77531
+- Owner: codex
+- Status: Ready for Integration
+
+## Scope
+
+- Merge verified source commit `8509084` into the integration branch.
+- Promote the accepted Learning download behavior into ADR-005, architecture,
+  domain rules, success criteria, README, server contract, current state,
+  evidence, and the pending production-smoke commitment.
+- Advance local `main` without overwriting its pre-existing untracked task
+  record.
+
+## Intent And Constraints
+
+- Follow the user's explicit decision that project downloads must not perform
+  archive-size validation.
+- Preserve Main ownership of authentication, fixed archive routes, same-origin
+  redirects, native destination selection, SHA-256, ZIP signature, temporary
+  files, cleanup, and atomic rename.
+- Keep the Works Square upload/storage size policy distinct from client download
+  behavior: the service may retain an independent operations upload limit, but
+  Makelore does not enforce it while downloading.
+- Do not modify, add, remove, or adopt the unrelated untracked record already in
+  the canonical `main` worktree.
+
+## Outcome
+
+- Merged source commit `8509084` through integration merge `0c1a360`.
+- Promoted the no-size-validation behavior into ADR-005, the decision index,
+  system overview, module map, data flow, domain rules, glossary, success
+  criteria, current state, evidence index, README, server collaboration
+  contract, and Learning production-smoke commitment.
+- Kept the optional 512 MiB rule only as an independent Works Square operations
+  upload/storage policy; Makelore does not enforce it during download.
+- Preserved SHA-256, ZIP signature, same-origin redirects, account binding,
+  temporary-file cleanup, and atomic save.
+
+## Verification
+
+- Pinned pnpm 10.33.4 frozen install: passed.
+- Focused Learning tests: `2` files, `17 passed`.
+- Full unit suite: first run had one unrelated Robot async-loading test failure;
+  that test passed immediately in isolation, and the complete rerun passed
+  `176` files / `2061` tests.
+- `pnpm run typecheck`: passed.
+- `pnpm run lint:check`: passed with zero errors and six pre-existing warnings.
+- `pnpm run build:vite`: passed for Renderer, Main, Preload, and utility worker;
+  existing dynamic-import and chunk-size advisories only.
+- Canonical size-rule scan and `git diff --check`: passed.
+- Independent sub-agent review was not run because the user explicitly required
+  that no sub-agents be created; final integration review stayed in the primary
+  task.
+
+## Follow-ups
+
+- Package and smoke the merged client with a real archive response that omits or
+  misreports `Content-Length`.
+- Monitor disk-space behavior for very large archives because the client now has
+  no archive-size ceiling by explicit product decision.
+
+## Promotion Candidates
+
+- None; accepted source-task candidates were promoted in this Integration Gate.

-# Task: Remove Learning archive size validation
-
-## Identity
-
-- Task ID: 20260820-remove-download-size-check-4f8a2c1d
-- Mode: Feature
-- Branch: codex/20260820-remove-download-size-check-4f8a2c1d-remove-download-size-check
-- Worktree: D:\Datas\OthersProjects\makelore-remove-download-size-check-4f8a2c1d
-- Base commit: 2168e291b2bf8ac8690c482f56400554a8d77531
-- Owner: codex
-- Status: Ready for Integration
-
-## Scope
-
-- Remove Learning project ZIP download checks that reject a response because of
-  an archive byte limit, declared archive size, or `Content-Length` mismatch.
-- Keep the existing authenticated Main-owned download route, controlled
-  same-origin redirects, SHA-256 verification, ZIP signature validation,
-  temporary-file cleanup, and atomic final rename.
-- Add focused regression coverage proving a valid archive downloads even when
-  its reported sizes are absent, inconsistent, or above the former limit.
-
-## Intent And Constraints
-
-- Follow the user's explicit direction to download without any size validation.
-- Do not expose Works credentials, upstream archive URLs, temporary paths, or
-  final local paths to Renderer.
-- Do not weaken digest or ZIP-format integrity checks; those are independent of
-  archive size validation.
-- Limit production changes to the existing Electron Main Learning download
-  service and focused tests.
-- This is a feature task, so canonical project memory remains unchanged until a
-  later Integration Gate.
-
-## Outcome
-
-- Electron Main no longer reads or compares archive `Content-Length`, project
-  `archiveBytes`, actual streamed bytes, or the former 512 MiB ceiling when
-  saving a Learning project.
-- Learning project DTO projection accepts positive safe-integer archive sizes
-  above the former client limit so those projects can reach the download flow.
-- SHA-256, ZIP signature, MIME, account-binding, redirect/origin, temporary-file
-  cleanup, and atomic rename checks remain unchanged.
-- Added regressions for omitted `Content-Length`, inconsistent reported sizes,
-  and metadata above the former limit.
-
-## Verification
-
-- Red phase: the two new size-removal regressions failed against the old
-  implementation with `LEARNING_PROJECT_INVALID` and
-  `LEARNING_INVALID_RESPONSE`.
-- Focused Learning tests: `2` files, `17 passed`.
-- Full unit suite via pinned pnpm 10.33.4: `176` files, `2061 passed`.
-- `pnpm run typecheck`: passed.
-- `pnpm run lint:check`: passed with zero errors and six pre-existing warnings.
-- `pnpm run build:vite`: passed; existing dynamic-import and chunk-size
-  advisories only.
-- `git diff --check`: passed.
-- Independent sub-agent review was not run because the user explicitly required
-  that no sub-agents be created; final review was performed in the primary task.
-
-## Follow-ups
-
-- Integrate the source commit into `main`.
-- During Integration Gate, reconcile all canonical documentation and remove the
-  obsolete size-failure smoke cases listed in the promotion candidate below.
-
-## Promotion Candidates
-
-- Target: ADR-005, Learning system overview/domain/current state, `README.md`,
-  `docs/learning-project-catalog-server-contract.md`, success criteria, and the
-  Learning release commitment.
-  - Proposal: remove the client download byte ceiling and all declared/
-    transport size consistency requirements while retaining same-origin
-    redirects, SHA-256, ZIP signature, temporary-file cleanup, and atomic save.
-  - Evidence: explicit user direction and focused download regressions from
-    this task.
-  - Future impact: the desktop client may consume disk space according to the
-    upstream archive size; server-side publication/storage policy may still set
-    independent upload limits, but they are not enforced during client download.
-  - Semantic conflicts: supersedes the 512 MiB and declared-size requirements
-    in accepted ADR-005 and its derivative documentation and smoke checklist.
-  - Human confirmation required: no; the user explicitly requested removal of
-    download size validation.
