Reconcile the Bucket A file count.

The listed counts sum to 201, but the bucket is declared as 235 files. This leaves 34 added files unaccounted for. Add the missing categories or correct the total before using this document as the extraction plan.

Strategy: these move into the amicode repo's app bundle unchanged. Their
imports reference sibling upstream modules — that coupling is what the bundle's
peer-dep on `@opencode-ai/*` packages resolves at build time.

Define the import adaptation step.

Bucket A is described as moving “unchanged” and “verbatim,” but packages/ui/src/amicode/* is also defined as requiring import adaptation to @opencode-ai/sdk. Document the exact transformation and affected paths, or make both documents use the same contract.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Correct the “16 largest” table count.

The table contains 11 file rows, not 16. Add the five omitted files or change the heading to match the listed entries.

largest” inventory section so its heading matches the 11 file rows currently
listed, or add the five missing file entries with their corresponding deltas and
descriptions. Keep the table and surrounding inventory context consistent.


A large fraction of "M" is upstream files that EXIST but whose content is
substantially ours (the +N/−0 shape) — effectively bucket-A files living at
upstream paths. The true behavioral overlays (home, session-header,
message-part, timeline, status-popover) are the files needing a compose/re-export
strategy: the bundle re-exports the upstream module with Amicode extensions
applied, rather than forking the file wholesale.

## Bucket D — deleted (4): re-delete at build

`debug-bar.tsx` (deliberate fork deletion, per AMICODE-PATCHES policy),
`link.tsx`, `notification-click.ts` (+test). The bundle's build applies these
deletions over the pinned upstream tree.

## i18n

The 72 amicode-era English keys (filled into 17 locales as EN fallbacks —
AMICODE-PATCHES 2026-08-01) live in the `language.tsx` modifications. They move
into the bundle's own locale tables, ending the upstream parity-test coupling.

## Overlay architecture (the decision this inventory implies)

1. The amicode repo gains `packages/app-bundle/` holding bucket A verbatim +
overlay modules for the true-M files + the i18n tables + bucket-D deletions.
2. A pinned upstream checkout (canonical release tag, from
`anomalyco/opencode`) provides the base; the bundle builds against it via
the workspace's package graph (`@opencode-ai/ui`, `@opencode-ai/app`
internals as peer deps).
3. CI pins the bundle to a canonical release (the same pin the updater
manages) and fails on API drift — the recurring post-cutover cost, made
loud at build time instead of silent at runtime.
4. Extraction order (each slice independently shippable):
a. `ui/src/amicode/**` (108 files, zero upstream-file edits)
b. app components with the +N/−0 shape (effectively additive)
c. the true overlays (home, session-header, message-part, timeline,
status-popover) — the files where compose-vs-fork judgment is needed
d. i18n tables + deletions + e2e port

## Honest scoping note (2026-08-20, night session)

This inventory is the M2 INPUT, not the extraction. The 411-file move is the
plan's declared long pole; the slices above are estimable now that the buckets
are counted. What is NOT done tonight: the bundle itself, its build, the
consumer flip (deck panes pointing at the service origin), and the CSP/origin
wiring — all tracked as the remaining M2 scope. M3 (cutover + ≥7-day dogfood
soak) and M5 (the one-push release) are gated on M2 by design.
