process/ holds the procedure, the five lens texts, the templates and the
skill under process/skill/prepush/. A lens text's sha256 is part of every
reuse key and the texts are part of every prompt, so they carry no SPDX
header; --version prints the charter hashes: 1728bd4c, 148d5c4c,
c7ffef44 and 2b9a5f83 for the four charters.
Home() finds them: CRAFTER_REVIEW_HOME, natively only (a host setting
must not swap the Flatpak's texts for a checkout's), then
<exe>/../share/crafter-review, then the checkout the binary was built in.
Main() hands `__supervise` to the supervisor before anything else, then
decides the sandbox once.

:Process makes sure no child outlives what it was started for. SIGKILL to
the direct child alone would leave the Playwright server and Chromium
running after a timeout, and every pass running after a SIGKILLed driver:
- every child is forked by one long-lived spawner thread, the reaper's
registry locked across fork, so PR_SET_PDEATHSIG holds and a fast exit
is never reaped unregistered; one reaper thread owns waitpid(-1);
- the child gets an empty signal mask, SIGPIPE and SIGXFSZ at their
defaults, and nothing but its three streams (close_range); the driver
ignores SIGPIPE and takes SIGINT/SIGTERM/SIGHUP on a thread of its own;
- `crafter-review __supervise <argv>` is a pass's subreaper. It kills the
pass's whole tree, Chromium's detached process group included, when the
target exits, on SIGTERM, and when the driver dies, by its death signal.
- Run() captures both outputs without the deadlock.
The shared state the detached threads wait on is never destroyed: a
condition variable destroyed under a waiter makes glibc's
pthread_cond_destroy, and with it exit(), wait forever.
:Platform: the Flatpak sandbox decided once, the host's XDG directories
restored there; WriteAtomic and LockedUpdate, the read-modify-write of
the board, ledger, memory.json and unit-state.json every driver on the
machine shares, under flock(2) on the same side files; /proc readers; and
the identity other drivers can check: natively pid and start time, in the
sandbox the instance's host pid from bwrapinfo.json with /proc/1's start
time. The lifetime lock is created under a temporary name and renamed into
place, so no prober ever finds it unlocked while its driver lives.
Tests: Process (the three ways a pass's tree must die, return codes, a
missing program, capture, timeouts, fds, the child's signal state),
Platform (atomic writes, LockedUpdate against a damaged file, two writers,
and another process holding flock on the side file; /proc on a fake
tree; both identities; the lifetime lock; the XDG restore).

What the rest of crafter-review stands on.
- project.cpp: a static crafter.review-lib and the crafter-review
executable; Crafter.Network without QUIC, pinned, or with --local from
the checkout next to this one; Crafter.LintRules' lite rules, pinned;
the version from CRAFTER_REVIEW_VERSION, git describe or 0.0.0-dev.
- :Core and :Driver: the version, PromptVersion 1, --version.
- :Json: nlohmann's ordered_json, which keeps key order and unknown keys,
so the files every driver on a machine shares survive a rewrite; dumps
in the indented file layout, the spaced one-line form and the compact
sorted form the structured-output schema needs byte for byte.
- :Crypto: SHA-256/SHA-1/MD5, HMAC, PBKDF2 through libcrypto; base64 and
base32 written out, because what they refuse, and with which message,
is pinned.
- :Unicode, Unicode 16.0.0's tables: whitespace, line breaks, decimal
digits, printable characters, case mappings and case-insensitive folds.
- :Text: string functions on code points, number parsing, the shortest
float form and half-even rounding, printed values, shell patterns, URL
splitting and unquoting, POSIX paths, universal newlines and the
replacing UTF-8 decoder.
Tests: Crypto (published vectors), Text (293 reference vectors).

lib/json.hpp is the release header of nlohmann/json 3.12.0, unmodified
(MIT; sha256 aaf127c0...dfc5de63, as downloaded from the v3.12.0
release). It compiles in a module's global fragment with clang 23, so
the develop snapshot Crafter.AI carries is not needed here.
