From 65df3f4fadc25b16172f92559a8fee72e74d8bc5 Mon Sep 17 00:00:00 2001 From: kami Date: Sat, 13 Jun 2026 15:18:27 +0400 Subject: [PATCH] =?UTF-8?q?feat(tui,kernel):=20deterministic=20command-app?= =?UTF-8?q?roval=20parse=20layer=20(=C2=A75.1)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Layer 1 of tui-requirements §5: a no-LLM analyzer that shell-lexes a proposed command, classifies binaries against a known-command table, and mechanically flags the constructs that widen blast radius — sudo/doas, recursive delete, pipe-to-shell (skipping wrappers so `| sudo sh` counts), redirects outside the workspace, network binaries, base64/eval, and unparseable input (itself a red flag). Pure + replay-stable: same preview + workspaceRoot → same analysis, no environment reads. The approval band renders command approvals as a card — worst-first flag chips over the reconstructed command line, each token colored by severity (T0–T4 ramp). ^x opens a scrollable fullscreen view so a long command is never truncated. Diff and plain-preview paths are unchanged. Server: computeToolPreview now renders the shell tool's argv as a full, shell-quoted command line instead of the 200-char JSON-args fallback, honouring §3's "full untruncated command". The TUI parser accepts both the rendered line and the older `{"argv":[...]}` shape for replay. Layer 2 (model annotation) deliberately deferred per the spec. --- apps/tui-go/internal/app/cmdcard.go | 594 ++++++++++++++++++ apps/tui-go/internal/app/cmdcard_test.go | 138 ++++ apps/tui-go/internal/app/demo.go | 5 +- apps/tui-go/internal/app/overlays.go | 70 ++- .../orchestration/SessionOrchestrator.kt | 24 + 5 files changed, 824 insertions(+), 7 deletions(-) create mode 100644 apps/tui-go/internal/app/cmdcard.go create mode 100644 apps/tui-go/internal/app/cmdcard_test.go diff --git a/apps/tui-go/internal/app/cmdcard.go b/apps/tui-go/internal/app/cmdcard.go new file mode 100644 index 00000000..5ad86f62 --- /dev/null +++ b/apps/tui-go/internal/app/cmdcard.go @@ -0,0 +1,594 @@ +package app + +import ( + "encoding/json" + "sort" + "strings" + + "github.com/charmbracelet/lipgloss" +) + +// cmdcard.go is layer 1 of tui-requirements §5 — the deterministic command-approval +// parse.
