M2 slice (a): app-bundle — the complete packages/ui overlay (equivalence + build proven) - #486
Conversation
…ens, self-tracking pin assertion
Main bumped the vendored fork twice (.13/.14, 0.2.4 release). Re-recorded
all 71 golden entries against the new binary: ZERO behavioral drift on
the amicode route surface (the 13 body diffs are sandbox paths and
wall-clock stamps, all replay-normalized; the about-you description
commit was widget-side only). Both documented post-pin divergences
STAND on .14 (auth route still serves the SPA; google auth_methods
still browser-only) — normalizations + unit tests unchanged, comments
updated.
The contract test's pin assertion now reads opencode.lock.json instead
of a hardcoded tag: a future pin bump without a re-record fails loudly
('recorded parity claim is stale') instead of silently testing the old
binary's behavior.
Also hardens the recorder: every fetch now carries a timeout (health
poll 5s, requests 20s) — an earlier recording hung indefinitely when a
boot wedged under machine load because a hanging fetch neither resolves
nor rejects, so the catch never fired.
Contract suite 74/74; full suite 1196/1196; typecheck clean.
…uivalence- and build-proven M2 slice (a) of #451: packages/app-bundle — the fork-owned app surface carried as an overlay on a pinned canonical base, the mechanism that retires the fork at cutover. Slice (a) scope: the COMPLETE packages/ui delta at v1.18.10-amicode.14 — 164 files (142 added, 22 modified; machine-derived, manifest.json carries the per-file classification). Not hand-picked: materialize(base, overlay) is byte-identical to the fork's packages/ui at the pin. BASE CORRECTION: the fork's true upstream base is v1.18.12~1 (b0b114923) — the 2026-08-04 merge landed upstream up to just-before the v1.18.12 tag (whose final commit only bumps version strings). The v1.18.12 release tarball is therefore the materialization base; the earlier v1.18.10-based inventory overcounted by folding in upstream's own 1.18.10→1.18.12 changes (corrected in docs/m2-app-extraction-inventory.md: 389 files, +41,953/−1,993, 244A/144M/1D). Proofs (both green): A. EQUIVALENCE — materialize(upstream v1.18.12 + overlay) produces a packages/ui byte-identical to the fork's at the pin (diff -r: zero). B. COMPOSITION — the materialized tree installs (bun install, 4695 packages) and builds (tsc -p tsconfig.build.json) cleanly, emitting 220 files incl. dist/amicode/*. Tooling: extract_overlay.mjs (git-archive AT the tag, never the working tree; per-file round-trip verification; deterministic hashes) + materialize.mjs (tarball cache per tag, overlay apply, manifest deletions, hash verification of every overlay file in the output). The inventory doc is stamped with slice (a) shipped.

The header comment at Lines 111-113 states that every save is a POST that remounts each widget iframe, and the drag path therefore commits once at drop. The keyboard path calls
moveon every arrow keypress, so each keypress issues a save and remounts every iframe. A held arrow key produces a burst of POSTs and remounts.The remount also destroys the focused cell, so focus is lost after the first keypress and the user must re-focus the card to continue reordering.
Consider holding a local order for the keyboard path and committing it on blur or after a short debounce, and restoring focus to the moved cell after the commit.

props.disabledis read once during setup. In Solid, a component body runs one time, so a later change fromfalsetotrue(or the reverse) does not hide or show the rail. A session that becomes "unrelated" keeps its rail.The early return also happens after the ask, approval, and UI bridge registrations and after the polling effect is created.

Part of #451 (M2 slice (a); not closing).
What's here
packages/app-bundle— the fork-owned app surface carried as an overlay on a pinned canonical base: the mechanism that retires the fork at cutover while keeping every Amicode surface.Slice (a) = the complete
packages/uidelta at the current pin — 164 files (142 added, 22 modified), machine-derived by the extractor, not hand-picked.The base correction (found building this)
The fork's true upstream base is
v1.18.12~1(b0b114923) — the 2026-08-04 merge landed upstream up to just-before the v1.18.12 tag, whose final commit only bumps version strings. The v1.18.12 release tarball is therefore the materialization base. The original inventory (v1.18.10-based, 411 files) overcounted by folding in upstream's own 1.18.10→1.18.12 changes; the corrected amicode-only delta is 389 files, +41,953/−1,993 (244A/144M/1D) — the inventory doc is corrected with a note.The two proofs (both green)
materialize(upstream v1.18.12 + overlay)produces apackages/uibyte-identical to the fork's atv1.18.10-amicode.14(diff -r: zero lines).bun install, 4,695 packages) and builds cleanly (tsc -p tsconfig.build.json), emitting 220 files includingdist/amicode/*.The build proof earned its keep: the first pass failed on
use:sortable(Solid directive types — the fork'ssolid-dnd.d.tslives outsidesrc/amicode), which is exactly how the hand-picked-scope bug showed itself. The complete-delta scope fixes the class, not the instance.Tooling
scripts/extract_overlay.mjs— extracts AT the tag viagit archive(never the working tree), round-trip-verifies every file againstgit show TAG:<path>, records per-file sha256 + A/M classification + deletions inmanifest.json.scripts/materialize.mjs— fetches the canonical tarball once per tag (cached, gitignored), copies the base tree, applies overlay adds/overwrites, applies manifest deletions, verifies every overlay hash in the output.Remaining M2 (per the inventory)
Slices (b)–(d): app + session-ui additive files, the true overlays (home, session-header, message-part, timeline) decomposed into composable extensions, i18n/e2e; the bundle's CI pin; the consumer flip (deck panes → service origin, CSP/
?auth_token=wiring).Summary by CodeRabbit
