config: add tlc to redbear-mini and redbear-full; create recipe symlink

TLC (Twilight Commander) was missing from both ISO configs. Added tlc = {} to [packages] in redbear-mini.toml and redbear-full.toml. Created missing symlink: recipes/tui/tlc -> ../../local/recipes/tui/tlc.

+# Red Bear OS Custom Recipes — Catalog
+
+All recipes under `local/recipes/` are Red Bear OS originals or patched forks of upstream
+Redox recipes. They are symlinked into `recipes/<category>/` at build time via
+`local/scripts/apply-patches.sh`.
+
+**Convention**: recipe directories contain `recipe.toml` (build instructions) and optionally
+`source/` (source code for Rust `cargo` or `custom` templates). Patches for upstream sources
+live in `local/patches/<component>/`, never here.

+# PipeWire — audio/video graph server (Red Bear OS).
+#
+# This recipe pulls upstream freedesktop PipeWire 0.3.85
+# (https://gitlab.freedesktop.org/pipewire/pipewire, tag 0.3.85) at the
+# pinned revision, then applies Red Bear OS external patches from
+# local/patches/pipewire/ on top of the upstream tree.
+#
+# Per AGENTS.md Rule 2 (NO OVERLAY-STYLE PATCHES — AMENDED 2026),
+# PipeWire is a big external project (multi-thousand-line codebase with
+# a fast-moving upstream). Red Bear does NOT maintain a source fork of
+# PipeWire — external patches in local/patches/pipewire/ keep us close
+# to upstream, give a clean audit trail (one mbox-style patch per Red
+# Bear change), and make upstream syncs a `rev = "..."` bump + patch
+# rebase instead of a full rebase of a Red Bear fork.
+#
+# All Red Bear-specific PipeWire changes (redox_compat/ shim headers
+# for byteswap.h and sys/mman.h, __redox__ guards in mem.c/thread.c
+# for memfd_create / pthread_setname_np / sched_get_priority_*) live
+# as external patches under local/patches/pipewire/. To add a new
+# PipeWire change:
+#   1. make the change in the fetched tree
+#   2. `git diff > local/patches/pipewire/NN-short-description.patch`
+#   3. add a `git apply` line in [build].script in apply order
+#   4. commit the patch in the main repo
+#
+# Red Bear OS uses PipeWire as the audio backend for KDE Plasma,
+# providing PulseAudio-compatible semantics for applications (libpulse
+# / libpipewire) and exposing audio routing to the compositor and
+# session manager.
+#
+# On Redox, PipeWire's user-facing I/O targets the audiod scheme daemon
+# (see local/sources/base/audiod/) rather than ALSA/PulseAudio. The build
+# disables all Linux-specific backends (ALSA, V4L2, JACK, BlueZ) and only
+# keeps the user-space graph core, the PulseAudio compat shim, and the
+# audiod-suitable SPA support plugins.
+#
+# Known gaps (intentional TODOs in the upstream source, documented in
+# the local/patches/pipewire/*.patch headers):
+#   * alsa / bluez5 / v4l2 / jack spa plugins — Linux-specific, not built
+#   * pipewire-alsa / pipewire-v4l2 / pipewire-jack — Linux-only compat shims
+#   * systemd activation — not available on Redox; we use init.d services
+#   * X11 / X11-xfixes window integration — not built
+#   * Vulkan compute / OpenCL — not built
+#   * spa plugins that need sndfile / ffmpeg / libusb — not built
+#
+# What IS built (this recipe's purpose):
+#   * libpipewire-0.3.so           — the client library
+#   * libspa-0.2.so                — the Simple Plugin API library
+#   * pipewire / pipewire-pulse     — the daemon and PulseAudio compat shim
+#   * pw-cli / pw-cat / pw-dump     — control utilities
+#   * SPA support plugins (aec, audioconvert, audiomixer, control, volume)
+#
+# Historical: a Red Bear fork of PipeWire previously lived at
+# local/sources/pipewire/. The fork is preserved as a reference of the
+# migration baseline but no longer used by the build system. A follow-up
+# commit will remove it after we verify a clean rebuild from upstream

+# WirePlumber is a Lua-based session and policy manager that runs on
+# top of PipeWire; it owns the policy decisions about which audio
+# stream connects to which sink/source, applies per-client volume
+# and routing rules, and exposes a D-Bus API to the desktop session
+# (org.freedesktop.PipeWire.Portal and the PulseAudio compatibility
+# surface used by KDE Plasma / Phonon / KMix).
+#
+# Red Bear OS uses WirePlumber as the PipeWire session manager so
+# that KDE Plasma and the Plasma audio applets can talk to a real,
+# configurable PipeWire stack rather than the upstream "no-session"
+# fallback.
+#
+# On Redox, WirePlumber talks to:
+#   * libpipewire-0.3 (this recipe's sibling, local/recipes/libs/pipewire)
+#   * libspa-0.2       (shipped with the pipewire recipe)
+#   * glib-2.0         (already a Red Bear dependency)
+#   * D-Bus            (for activation and for KDE's org.pulseaudio.Server)
+# The build disables the optional systemd / elogind integration paths
+# since Redox uses init.d, and disables the optional PulseAudio
+# helper that is only relevant on systems that still ship a
+# PulseAudio daemon (Red Bear does not — pipewire-pulse replaces it).
+#
+# Known gaps (intentional TODOs in the source fork, documented in
+# the patch's README-redbear.md):
+#   * systemd / elogind integration — Redox uses init.d
+#   * wireplumber.options Lua config — needs to be staged by the
+#     recipe's [[files]] entry; not committed to the patch
+#   * LuaJIT is preferred over the system Lua when both are available;
+#     Red Bear currently ships neither and depends on the bundled Lua
+#     subproject (downloaded via meson wrap on first build; we plan
+#     to vendor it once the wrap cache is committed)
+#
+# What IS built (this recipe's purpose):
+#   * libwireplumber-0.4.so         — the C client library
+#   * wireplumber                   — the session manager daemon

+"""Audit every KF6/Qt recipe's [build].dependencies against what its source
+actually requires.
+
+For each recipe under local/recipes/kde/ and recipes/, this script:
+  1. Resolves the upstream source (git or tar) at the pinned rev
+  2. Extracts/reads the source's CMakeLists.txt + all .cmake files
+  3. Greps for `find_package(KF6::* COMPONENTS ...)` and `find_package(Qt6* ...)` calls
+  4. Reads the recipe's [build].dependencies array
+  5. Reports any KF6::/Qt* component referenced in the source but missing
+     from the recipe's dependencies, AND any recipe dependency that is
+     unused (i.e. not referenced by the source)
+  6. Optionally: emits a fixed [build].dependencies array as a patch
+
+Per AGENTS.md "BUILD DURABILITY" policy, the recipe.toml is the durable
+artifact. This audit ensures the recipe matches what the source actually
+needs, preventing "Package 'X' not found" failures at cook time.
+
+Usage:
+  ./local/scripts/audit-kf6-deps.py --verbose          # audit all 46 recipes
+  ./local/scripts/audit-kf6-deps.py --component kf6-kio
+  ./local/scripts/audit-kf6-deps.py --fix --dry-run    # show proposed fix

+"""Validate the idempotency of every external patch in local/patches/.
+
+Per AGENTS.md "NO OVERLAY-STYLE PATCHES — AMENDED 2026" Rule 2, big
+external projects use the cookbook's `cookbook_apply_patches` helper
+which checks `git apply --reverse --check` to skip already-applied
+patches. If a patch's reverse check fails (because the upstream
+source drifted from the patch's expected state), the helper tries to
+
+JSON SCHEMA (with --json):
+  Top-level:
+    patches:        [PatchEntry, ...]   one per patch in local/patches/
+    total:          int                  len(patches)
+    errors:         int                  count of all_errors across all entries
+    skipped:        int                  count of entries that were --no-fetch
+  Per-entry:
+    component:      str                  e.g. "mesa", "libdrm"
+    patch:          str                  filename, e.g. "01-foo.patch"
+    status:         "ok" | "fail" | "skipped"
+    errors:         [str, ...]           empty unless status == "fail"
+  Exit code: 0 if errors == 0, else 1. With --no-fetch, all entries are
+  "skipped" and the exit code is still 0, so the make lint-patches
+  target chains should treat skipped_count == total as a soft failure.
+
+apply the patch forward, which fails too because some hunks no
+longer apply. The result is a confusing cook failure.
+
+This script catches that class of bug at lint time. For every
+[0-9]*.patch under local/patches/<component>/, it:
+
+  1. Clones the upstream repo at the pinned rev into a temp dir
+  2. Applies the patch
+  3. Verifies `git apply --reverse --check` succeeds on the result
+     (i.e. the patch is fully reversible — idempotency invariant)
+  4. Re-applies the patch
+  5. Verifies the source is byte-identical to step 2's result
+     (i.e. the patch is idempotent — applying it twice = applying it once)
+  6. Verifies the result is reproducible: re-clone, re-apply, byte-equal
+
+If any check fails, the script exits non-zero and prints which patches
+are non-idempotent. CI or `make lint` should run this on every PR.

+"""Classify a failed `repo cook` output and suggest a fix.
+
+Per AGENTS.md "COMPLEX FIX CHECKLIST (v6.0-impl17)" §19.25, the Red Bear
+OS cookbook build can fail in ~12 distinct, well-understood ways.
+This script scans the tail of a build log and matches it against the
+known failure patterns, then points the user at the documented fix.
+
+Usage:
+  repo cook kf6-kio 2>&1 | tee /tmp/build.log   # capture the failure
+  classify-cook-failure.py /tmp/build.log        # analyze the log
+  classify-cook-failure.py --last                # analyze the last build log
+
+JSON SCHEMA (with --json):
+  Top-level:
+    log:             str                   path to the analyzed log file
+    matched:         [Rule, ...]           one per rule that fired
+    matched_count:   int                   len(matched)
+  Per-rule:
+    name:             str                  rule name
+    patterns:         [str, ...]           regex patterns (raw)
+    context_required: [str, ...]           tokens that must appear in the log
+    fix:              str                  multi-line fix text
+    ref:              str                  AGENTS.md §19.25 reference (or "")
+  Exit code: 0 if matched_count == 0, 1 if matched_count > 0. This is
+  CI-safe: a non-zero exit is the SIGNAL "I found a known failure".
+
+JSON exit code is INTENTIONALLY inverted vs the audit scripts (which
+return 0 on clean). Here, exit 0 = "no known pattern matched" (novel
+failure, need human triage) and exit 1 = "I identified the problem
+and told you the fix". A CI job that wants to PASS on a known fix
+should treat exit 1 as a pass; a job that wants to detect novel
+failures should treat exit 0 as a fail.
+
+
+If the failure is not in the known list, the script falls back to
+generic guidance (clear sysroot, re-fetch source, escalate to debug).

+Per `local/docs/BUILD-SYSTEM-IMPROVEMENTS.md` build-system
+improvement #5, this script validates a single recipe's
+[source] / [build] / [package] blocks against the v6.0 fork
+model (Rule 1 in-tree direct edit, Rule 2 external patches).
+
+Build-time recipe lint catches policy violations BEFORE the slow
+cook starts. Each rule has:
+  - id:           short identifier (e.g. R1-NO-PATCH-FILE)
+  - severity:     error | warning
+  - description:  one-line human-readable summary
+  - check(path):  the actual validation function
+
+Exit code:
+  0  = clean (no errors; warnings allowed)
+  1  = errors found (one or more `severity: error` rules failed)
+  2  = bad usage (no recipe path, file not found, etc.)
+
+Usage:
+  ./local/scripts/lint-recipe.py <recipe-path>          # lint one
+  ./local/scripts/lint-recipe.py --all                  # all recipes

+# Red Bear OS — C-7 direct-sed migration
+#
+# For KF6 recipes whose [build].script uses inline `sed -i`
+# chains, this script:
+#   1. Restores the pristine source from `source-pristine/`
+#   2. Applies the same sed chain manually via `bash -c`
+#   3. Diffs pristine vs post-sed source
+#   4. Saves the diff as `local/patches/<name>/01-initial-migration.patch`
+#
+# Why direct-sed instead of `repo cook`: the cookbook's
+# `cook` step does a full dep-tree build that often fails
+# in offline mode (missing libffi/pcre2/mesa stage.pkgar
+# etc.). The sed chain we care about is the FIRST thing
+# in the recipe's [build].script and runs BEFORE cmake
+# configure. We can run it standalone with a simple
+# `bash -c "<sed chain>"` to capture the post-sed state.
+#
+# This is the same diff that `repo cook` would have
+# produced, but without the dep-tree failure mode.

+# migrate-kf6-seds-to-patches.sh — C-7 KF6 sed migration
+#
+# Walks the 56 KDE/Qt recipes in `local/recipes/kde/*` that have
+# inline `sed -i` chains in their `[build].script`, captures each
+# set of edits as a durable external patch in
+# `local/patches/<name>/01-initial-migration.patch`, and rewrites
+# the recipe to call `cookbook_apply_patches` instead of running
+# the sed chains inline.
+#
+# Per `local/AGENTS.md` "NO OVERLAY-STYLE PATCHES — SCOPED POLICY"
+# (Rule 2): edits to big external projects must live in
+# `local/patches/<component>/` so they survive `make clean` and
+# upstream syncs. The migration converts the 56-recipe
+# inline-sed anti-pattern into compliant Rule 2 recipes.
+#
+# Usage:
+#   ./local/scripts/migrate-kf6-seds-to-patches.sh [--dry-run]
+#                                       [--recipe=kf6-karchive] [...]
+#   ./local/scripts/migrate-kf6-seds-to-patches.sh --limit=N
+#
+# Pre-conditions:
+#   - All recipe dependencies built (qtbase, qtdeclarative, etc.)
+#   - Each recipe's `[source]` points at a tar (not git) so the
+#     pristine fetch is reproducible.
+#   - Disk space: ~2.8 GB for the unzipped source diffs + patches.
+#   - `git -C local/recipes/<name>/` is a clean working tree (or
+#     the script's `git checkout -- source/` reset will lose WIP).
+#
+# Per-recipe flow (per `bash` recipe):
+#   1. Parse `[source].tar` to compute the pristine URL.
+#   2. `repo fetch <name>` to get pristine source into `source/`.
+#   3. `cp -r source/ source-pristine/` snapshot.
+#   4. `repo cook <name>` to apply the inline sed chains.
+#   5. `diff -ruN source-pristine/ source/` to capture edits.
+#   6. Save diff as `local/patches/<name>/01-initial-migration.patch`.
+#   7. Rewrite `recipe.toml` `[build].script` to call
+#      `cookbook_apply_patches "${REDBEAR_PATCHES_DIR}"` instead.
+#   8. `repo cook <name>` again to verify the patch + rewritten
+#      script produce the same result as the inline sed.
+#   9. `rm -rf source-pristine/` and report the patch.

+#
+# Rebuild-from-scratch the subset of packages that use autotools
+# (or anything that transitively depends on them) after a
+# low-level source change (relibc, kernel, base, autotools
+# recipes themselves). Useful when the standard "cookbook
+# cascades rebuild on pkg/sources change" misses something
+# (e.g. a host toolchain change, a configure-flag change, or
+# a recipe's host build directory getting stale).
+#
+# The script:
+#   1. Discovers autotools-using recipes by content (presence
+#      of `aclocal`, `autoreconf`, `libtool`, or `configure` in
+#      the recipe's [build].script).
+#   2. Computes the transitive closure of every recipe that
+#      depends on any autotools recipe (or directly uses
+#      autotools itself).
+#   3. For each recipe in the closure, deletes its
+#      `target/<arch>/build/`, `target/<arch>/sysroot/`, and
+#      `target/<arch>/stage.tmp/` (preserving `source/` so we
+#      don't have to re-fetch the upstream tar).
+#   4. Re-cooks each recipe in dep order using the cookbook's
+#      `--jobs=N` flag (default: 4 workers) so the rebuild
+#      itself runs in parallel.
+#
+# Per `local/docs/BUILD-SYSTEM-IMPROVEMENTS.md` #10. The full
+# L-sized work (verification against real cascades, integration
+# with `rebuild-cascade.sh`, the cross-host-toolchain case) is
+# deferred to a separate session. This script is the

+# capture the serial console to a timestamped boot log.
+#
+# This script is the canonical QEMU launcher for the redbear-full live ISO
+# (or harddrive.img) per the Red Bear OS desktop path plan. It exercises:
+#   - ACPI / GPE / Notify plumbing (acpid + kernel AML interpreter)
+#   - v6.0 input architecture (evdevd + virtio-keyboard / virtio-mouse)
+#   - MSI-X USB (xhcid via virtio xhci passthrough) and EHCIfallback (ehcid)
+#   - multi-queue NVMe (nvmed with multiple queues via NVMe device)
+#   - virtio-gpu (redox-drm via /scheme/drm/card0)
+#   - virtio-net (e1000d / virtio-netd via net0 user-mode networking)
+#   - D-Bus system bus (dbus) and redbear-sessiond
+#   - SDDM + KWin Wayland compositor (when targeting redbear-full)
+#
+# The script auto-stops QEMU after BOOT_TIMEOUT seconds (default 60). The
+# captured log is written to local/docs/boot-logs/ and is suitable for offline
+# analysis (login presence, service startup, GPU registration, etc.).
+#
+# Usage:
+#   ./local/scripts/test-redbear-full-qemu.sh                 # default: ISO, 60s
+#   ./local/scripts/test-redbear-full-qemu.sh --img           # use harddrive.img
