Summary

Desktop edit-and-resend refused any selected message carrying attachments: the revision copy stops before the revised turn, so no target-owned refs existed client-side and the edit failed closed. This closes that last #5109 gap by staging the edited turn's artifacts into the copy and re-attaching them through the composer plates, the same flow quotes already follow (#5274).

• Runtime Host: a revision copy now includes the edited turn's user-uploaded artifacts (the include path built for uploads, whose sentinel turnId the turn-scoped selection misses) and the committed response carries the rewritten, target-owned stagedAttachments.
• Shared lifecycle (@maka/ui): edit start restages the source attachments as retained pending items; a successful prepare swaps their refs for the copy's target-owned ones and re-keys the plate onto the branch child; cancel drops the edit's own entries and keeps the user's. A rewrite missing from the response keeps its source ref, so the Host's session-owned guard fails that submit loudly rather than sending a dangling reference.

Fixes #5109

[ggbdpq]

First-round red was the protocol compatibility epoch guard: the new stagedAttachments response field is wire-observable (older peers reject the additional field in the strict copy-result decoder), so declaring it incompatible-free was not on the table. Bumped RUNTIME_HOST_COMPATIBILITY_EPOCH 227 -> 228 in ecfbaf69e; the guard now reports Protocol changed and the epoch moved: 227 -> 228.

Reviewed exact head ecfbaf69e0b276465e8529b57220e630362a6a90 against main 59f61cf7: 11 files, +371/-60. This copies the selected user turn's uploaded artifacts into a revision target, adds optional stagedAttachments to the committed response, forwards them through Desktop, and replaces the previous attachment-edit refusal with composer restaging and cancellation cleanup.

Three P2 findings are attached inline:

1. Desktop connects the new pending-item restorer to an existing AttachmentRef[] API. The normal root build fails with TS2322 at use-composer-attachments.ts:58, matching CI. With the actual shared React hook, beginning an attachment edit double-wraps the item: its displayed name/size disappear and toSubmittedAttachments() returns a pending object where an attachment reference should be. A conversion adapter in the probe preserves the original reference.
2. Cancellation compares a complete attachment object against just its .ref, so the edit's own attachment is never removed. The actual revision lifecycle leaves source.txt alongside a newly added new.txt after cancel. A reference-key-only control fixes cancellation before preparation; after preparation the rewritten target reference also needs identity tracking, or it is retained on the source draft after the target copy is abandoned.
3. The Host looks up an uploaded artifact ID in the filesystem-path map. The existing upload API returns ref.relativePath = record.id; copyConversationArtifacts() maps those through artifactIds, while relativePaths is keyed by the record's physical relative path. Against a real Host over UDS, editing the fixture's uploaded first-turn attachment commits without stagedAttachments. Looking in artifactIds first makes that same request return a target-owned reference. Without it, the composer has no replacement reference and the intended edit cannot submit safely.

Validation: fresh installation and dependency patches; the normal root build:test reaches Desktop and fails at the new type mismatch. The original protocol, staged-context, folder-attachment and real two-client Host revision tests pass (29 total). Additional probes use the actual shared attachment hook and revision actions, plus the existing real Host/storage fixture. Three added assertions fail at this head (hook shape and cancellation before/after prepare); the conversion-adapter control passes. Biome on all 11 changed files, ASF headers, whitespace checks, and the protocol epoch guard pass. The head merges cleanly with current main. No packaged Electron or native Desktop end-to-end run was performed, and the renderer build is blocked by the earlier type error.

P3 retry follow-up: please retain or reconstruct the new staged-reference result on the existing-target path (session-revision-coordinator.ts:770). With only the artifact-map lookup corrected in the probe, the first request returns a staged reference but an identical retry returns only the Session projection. This observation uses that lookup control; I am not counting it as an additional independently reproduced P2 on the unmodified head. The new result should remain usable across retries as well as initial creation.

Protocol: the strict response decoder accepts the new field and rejects malformed attachment shapes. Bumping compatibility epoch 227 to 228 is appropriate and passes the guard against current main. Other open PRs also propose 228; after any of them merges, use the next unused epoch and revalidate before merging this one.

CI: 39854063152 fails in the build on the same new TS2322 error reproduced locally. The description's successful Desktop typecheck claim does not hold for this head. The three P2 findings need fixing; this comment does not approve merging.

Reviewed the three follow-up commits at 5529fa931e0b33f710db110952667aac3f827ee4 (seven-file increment, +318/-28) after ecfbaf69. All three previous attachment P2 findings are fixed. One new P2 remains: protocol epoch 228 is already used by current main for a different strict wire contract. See the inline comment at the epoch declaration.

The Desktop controller now binds restorePendingAttachments, so pending items retain their display name, size and nested source ref. Cancellation records and removes edit-owned staging keys, which survive the target-ref rewrite, while preserving user-added files. The Host now checks artifactIds before relativePaths; a real uploaded artifact is returned under the target Session and its bytes remain readable.

After fresh dependencies and patches, the normal root test build, production renderer build and complete Desktop typecheck passed, including the previously failing controller type. All 27 protocol/lifecycle/real two-client Host tests passed. An additional actual shared-hook/revision check passed all 22 tests, including its imported lifecycle cases and cancellation before/after prepare. Rebinding only the old restorer reproduces the wrapped attachment failure (21 pass, 1 fail); loading the old cancellation module reproduces four carried-file retention failures (18 pass, 4 fail). A separate real Unix-socket Host probe returns a rewritten attachment on the first request; loading only the old coordinator loses that attachment again. Source files were unchanged for these controls. Seven-file Biome, ASF headers and git diff --check passed.

New P2: main 15d0a0dd19d39e2bc09ae35940e432c636982315 already advertises 228. This PR also advertises 228 while adding stagedAttachments to a closed response decoder. Loading main's actual decoder into the unchanged protocol suite makes the new accepted-response case fail with invalid_frame (5 pass, 1 fail). The actual epoch guard rejects this head against main, and a static merge also conflicts in protocol/index.ts. Rebase while retaining both contracts, choose an unused epoch above main, and run CI on the result. #6195 currently proposes 229 too; that number is not reserved for either PR.

The earlier P3 retry observation remains: repeating the exact same session.revision.create returns committed without stagedAttachments, although the first response includes them. The probe's post-restart response includes an attachment again; that does not establish durable replay of the original response. This follow-up does not demonstrate duplicate user notifications or cross-Session leakage.

There are no current-head CI checks or runs reported for this head. I did not run a packaged Electron edit/resend flow, native platform tests, or a reconciled merge build. Local attachment checks passing do not resolve the protocol P2 or establish current-head CI success.

[ggbdpq]

Merged current main (15d0a0dd1) into the branch: a sibling PR landed a different wire change under the same epoch 228 first, so this branch's stagedAttachments change re-sequences to 229 (b95dfc54d, conflict was exactly the sibling comment lines). The guard passes — Protocol changed and the epoch moved: 228 -> 229 — and the merge build + protocol/lifecycle suites are green (6/6, 19/19), format 2540 files clean, ASF headers clean, desktop typecheck exit 0.

Reviewed the merge at b95dfc54d4f2916abb77bb3d51dfedca17437439 against 5529fa93 and current main. The previous epoch P2 is fixed: the branch preserves main's epoch-228 executor-catalog contract and assigns the incompatible staged-attachment response epoch 229. The actual protocol guard passes 228 → 229; retaining 228 makes it fail. All twelve attachment implementation/test files outside the protocol index are byte-identical to the previous reviewed head.

New P2 — update the existing Desktop revision tests for the new attachment lifecycle. Current-head CI 39965827644 fails six tests across app-shell-revision-actions.test.ts, app-shell-revision-resend.test.ts and use-composer-quotes-revision-send.test.ts. The old attachment test still expects editing to be refused, while existing staging fakes omit the attachment restore/clear operations now used unconditionally in preparation (packages/ui/src/revision-staged-context.ts:563, :577). I reproduced 12 passes / 6 failures locally. Loading only main's previous lifecycle module makes all 18 pass. Keeping the new production code and updating only those test fixtures plus the obsolete refusal assertion also makes all 18 pass. These failures establish a test integration regression, not a separate claim that the real Desktop attachment surface lacks those methods.

Fresh dependencies/patches, the normal root build and renderer build passed. All 27 protocol, actual two-client UDS and shared attachment-lifecycle tests passed; protocol-file Biome, ASF headers, diff checks and static merge also passed. The three earlier attachment P2 fixes remain intact. The previous P3 still applies: an exact duplicate revision request can return the committed result without stagedAttachments; this merge does not change that response path. The PR description also still quotes an older epoch.

The PR is now conflict-free but its current CI is red for the confirmed test regression above. Epoch 229 is not reserved: recheck against main after other protocol PRs merge. I did not repeat the previous full attachment negative-control matrix or run a packaged Electron/IME edit flow, and I did not build a separate synthetic merge tree.

Reviewed 97107422f1021fa96eafdcd4903fe309275fd367, including the full PR diff and the single appended commit since b95dfc54. The increment changes only three Desktop test files (+36/-21): staging fakes now provide the attachment restore/clear methods, and the obsolete attachment-refusal assertion now checks the retained attachment, draft and composer text. All production files are byte-identical to the previously reviewed head.

The previous CI P2 is fixed; I found no new P0–P2 in this increment. With fresh dependencies and dependency patches, the normal clean root build:test passed and all 18 tests in the three affected files passed. Loading only those three test files from b95dfc54, while keeping current production modules, reproduces the same six failures (12 pass / 6 fail). This independently confirms the fixture integration fix. Another 27 protocol, real two-client UDS, attachment lifecycle and attachment-hook tests passed. Changed-file lint, ASF headers, diff checks and the actual protocol guard passed.

The earlier attachment fixes and valid epoch increase (228 → 229) remain intact. The existing P3 retry limitation remains at session-revision-coordinator.ts:775: the committed-target retry response still omits stagedAttachments; this test-only commit does not change that path. Recheck the next unused epoch when integrating other protocol PRs.

Current-head CI 40036945046 passed, and a static merge into current main 15d0a0dd1 is clean. I did not rerun the full Desktop/UI suites, renderer/type checks or the previous full attachment negative-control matrix, and I did not run a packaged Electron/IME edit flow or build the synthetic merge tree. The prior production-code review and its stated limits still apply.

[ggbdpq]

Closed the recorded P3 in e379bf0ad: the committed-probe retry path now answers with the same stagedAttachments the first attempt returned. The retry re-derives the edited turn's attachments and resolves their copies with existingTarget: 'reuse_verified' — nothing is re-copied, the store verifies ownership/payload and hands back the same maps — and the staging helpers moved to module scope so the retry path shares them with the primary copy. The two-client UDS suite gained a re-send assertion (retry of a committed upload-turn revision answers one target-owned ref whose artifact reads back retained bytes); it fails against the old bare-retry response and passes with the fix. Everything else in your review is already reflected: epoch 229 stands, CI on the previous head is green, and the PR description now carries the original-UUID wording.

Incrementally reviewed e379bf0ada256df36dae9da64207f31d4011cca9 against 97107422: one appended commit, two files, 115 additions and 37 deletions. The coordinator extracts the attachment-selection helpers and now reconstructs staged attachment refs on the committed-target retry path. The previous P3 omission is fixed while the target artifacts remain present.

P2 — a committed retry can recreate an attachment that another Client explicitly deleted (inline at session-revision-coordinator.ts:762). This path calls the artifact copy writer again after the conversation copy has already committed. existingTarget: 'reuse_verified' verifies an existing artifact, but creates a new copy when that target artifact is absent. It therefore does not make this committed-response reconstruction read-only.

I reproduced this through the real Host with two UDS Clients and actual artifact storage: Client A creates the revision and receives its staged upload; Client B successfully calls artifact.delete on that target upload, and a fresh artifact query confirms an empty target list. Client A then repeats the identical revision request. The upload record reappears under the original target ID, and a real read_text query returns the deleted payload (retained bytes). Loading only the prior coordinator implementation while retaining the current fixture leaves the deletion intact. The regression case fails on this head and passes with that prior implementation. Replay the committed attachment result using durable metadata or a read-only lookup that respects subsequent deletion, rather than invoking a copy operation that can publish artifacts again.

A fresh patched install and the normal clean root build:test passed. All 26 protocol, real two-client revision and shared lifecycle tests passed, as did the 18 Desktop revision tests. Changed-file Biome, diff checks and the protocol guard passed. This increment adds no protocol change beyond the existing valid 228 → 229 increase against main 15d0a0dd1; recheck the next unused epoch at integration. The static merge is clean.

The current-head CI test job was still running at the latest check; its result cannot resolve the independently reproduced deletion regression above. I did not rerun the full workspace suite, renderer build, all Desktop typechecks or the earlier full attachment control matrix, and I did not run a packaged Electron edit flow.

Incrementally reviewed d99aaae89a6da67ebeb54a52ffe40f29128445eb against e379bf0a: one appended commit, three files, 123 additions and 42 deletions. The copy's committed header now stores the landed source/target artifact pairs, and committed retries use getInSession rather than calling the artifact copy writer again.

The previous P2 attachment-resurrection regression is fixed. I found no new P0–P2 issue in this increment. In an extension of the real two-client UDS fixture, I created the attachment-bearing revision, restarted the Host, reconnected both Clients and repeated the original request. The replay returned the same staged attachment refs, confirming that the mapping survived persistence and restart. The other Client then successfully deleted that target upload, and a fresh artifact query confirmed an empty list. Repeating the identical revision request stayed committed, omitted the deleted attachment and left the list empty. Loading only the prior coordinator implementation reproduces the deleted record and its readable original payload. These checks use the real Host, SQLite, artifact files and Client operations; artifact writes were not mocked.

The new stagedArtifacts field is optional durable header metadata. There is no SQL table change. All 108 existing session-store/SQLite metadata tests passed, and the real restart case above verifies the new metadata's round trip. I did not test opening a State Root written by this head with an older Host binary.

Fresh dependencies and patches, the normal clean root build:test, all 26 protocol/two-client/shared-lifecycle tests, changed-file Biome and diff checks passed. The protocol guard accepts the existing 228 → 229 increase against current main 15d0a0dd1, and a static merge is clean. Recheck the next unused epoch when integrating other protocol changes.

The current-head CI test job is still running; this review does not claim CI success or release readiness. I did not rerun the full Desktop/UI suites, renderer build, all typechecks or the earlier complete attachment control matrix, and I did not run a packaged Electron edit flow. The independent restart/deletion probe specifically covers the user-upload path described above.

[ggbdpq]

Merged current main (15f8eba1c) into the branch: a sibling PR landed a different wire change under epoch 229 first (session check-in cards), so this branch's stagedAttachments change re-sequences to 230 (dfc990e62, conflict was the sibling comment lines). The guard passes — Protocol changed and the epoch moved: 229 -> 230 — and the two-client UDS suite plus the shared lifecycle suite are green on the merge (build needed the acp-plugin workspaces, an environment miss on my side, not a merge artifact).
