+Remaining tracked `src/` filename hits are limited to the literal `kapi-review` external integration CLI. Runtime package metadata no longer exposes a `kapi` bin, and the old direct `bin/kapi.mjs` shim is removed. Local ignored/generated fixture state under `src/.kapi` may exist in developer worktrees, but it is not part of the committed source tree scan.
+
+## Final acceptance scan counts
+
+The final issue #209 residual scans were run against the committed runtime-alias-retirement tree. Active `src/` content counts exclude only ignored/generated fixture state so the evidence is reproducible from a clean checkout:
+
+```text
+rg -n -i 'kapi' src --glob '!src/.kapi/**' --glob '!src/.git/**'
+# 501 matching lines / 590 matches across 36 active src files
+
+rg -n 'Kapi[A-Z]|\bkapi[A-Z_-]|kapi-' src test docs package.json package-lock.json
+# 1307 matching lines / 1491 matches across source, tests, docs, and package metadata
+
+rg -n '\b(class|interface|type|function|const|let|var|enum)\s+[A-Za-z0-9_]*Kapi[A-Za-z0-9_]*|\b(class|interface|type|function|const|let|var|enum)\s+kapi[A-Za-z0-9_]*' src
+# no internal reusable declaration-name hits
+```
+
+Active `src/` residual category counts:
+
+| Category | Lines | Matches | Files | Why retained |
+| --- | ---: | ---: | ---: | --- |
+| User-facing compatibility text | 228 | 240 | 25 | Status/help/diagnostic wording still describes the existing Kapi workflow contract exposed to users. |
+| Serialized workflow/event contracts | 124 | 147 | 20 | Workflow IDs, event kinds, run-contract source kinds, and persisted state keys remain compatibility contracts. |
+| Slash commands / public tool contracts | 99 | 126 | 12 | `/kapi-*`, `kapi_*`, and `@kapi:` surfaces are public contract names pending a separate migration plan. |
+| External review integration | 24 | 48 | 5 | `kapi-review`, `kapi-agent`, and `kapi-agent/review` are literal external integration names. |
+| Environment/runtime compatibility | 10 | 11 | 7 | `KAPI_*` environment variables remain compatibility inputs for runtime dispatch and tests. |
+| Other compatibility literals | 16 | 18 | 10 | Shell labels, fixture command strings, and small compatibility literals that are not reusable implementation identifiers. |
+
+## Issue #209 acceptance mapping
+
+| Acceptance criterion | Status | Evidence |
+| --- | --- | --- |
+| `src/` contains no `kapi` in filenames except explicitly justified boundary exceptions. | Met | Tracked filename scan has 1 hit: `src/cli/kapi-review-cli.ts` for the external review integration. Ignored/generated local `src/.kapi` fixture state is not part of the committed source tree. |
+| Internal reusable exports/types/functions/classes no longer use `Kapi*` / `kapi*` naming. | Met | Declaration-name scan returns no active `src` hits. Remaining exported literals are serialized contracts, event names, or external integration strings. |
+| Remaining `kapi` hits in `src/` are limited to documented compatibility contracts, serialized workflow IDs, slash-command literals, or intentionally named external integrations. | Met | Category table above classifies all 501 active `src` matching lines / 590 matches. |
+| Public runtime command examples remain `ilchul`; internal implementation names remain generic. | Met | Package bins are `ilchul` and `kapi-review`; runtime internals use `runctl` / `runtime` / `workflow` / `worker` names where reusable. |
+| Tests prove package/runtime CLI does not expose a `kapi` runtime alias. | Met | `test/cli-bin.test.ts` covers package-local `npm exec -- kapi --help` failure and isolated-prefix absence of a `kapi` shim. |
+| Final scan report includes remaining exception categories and counts. | Met | This section records filename, content, semantic scan, declaration scan, and residual category counts. |
 
 ## Remaining justified product-name identifiers
 
 - **External review integration:** `kapi-review`, `kapi-agent`, `kapi-agent/review`.
-- **Persisted contracts:** `/kapi-*` slash commands, `kapi-*` workflow IDs, existing serialized state expectations.
-- **Storage/config namespace:** `.ilchul`, `~/.ilchul`, `ILCHUL_*`, legacy `.kapi` references.
-- **External integration:** `kapi-agent`, `kapi-agent/review`.
+- **Persisted contracts:** `/kapi-*` slash commands, `kapi-*` workflow IDs, `kapi.worker.*` / `kapi.pr.*` event names, `kapi-workflow` run-contract source kind, and existing serialized state expectations.
+- **Public tool / command contracts:** `kapi_*` tool names and `@kapi:` UI completion syntax.
+- **User-facing compatibility text:** status, help, validation, and diagnostic strings that describe the still-public Kapi workflow contract.
+- **Storage/config namespace:** `.ilchul`, `~/.ilchul`, `ILCHUL_*`, legacy `.kapi` references, and compatibility `KAPI_*` environment inputs.
 - **Documentation/history:** prose explaining migration context or historical behavior.
