#!/usr/bin/env bash
# Publish rsleigh workspace crates to crates.io in topological order.
#
# Usage:
#   scripts/publish-all.sh           # live publish (IRREVERSIBLE)
#   scripts/publish-all.sh --dry-run # dry-run everything
#
# Prereqs:
#   cargo login <token>  (one-time)
#
# Order (13 crates total — collapsed from 43):
#   1. pcode-ir
#   2. generated/<arch> × 6   (each: leaf, only pcode-ir)
#   3. rsleigh-api            (needs all 6 generated)
#   4. rsleigh-decompile      (pcode-ir + rsleigh-api)
#   5. rsleigh-fid            (pcode-ir + rsleigh-api)
#   6. rsleigh-cli            (api + decompile + fid)
#   7. rsleigh                (root: optional `cli` feature → rsleigh-cli)
#   8. rsleigh-generate       (rsleigh)
#
# Cycle note: root `rsleigh` declares `rsleigh-cli` as an optional
# dependency (the `cli` feature). cargo publish validates ALL declared
# dep versions against the registry, even optional ones, so rsleigh-cli
# must be on crates.io before rsleigh publishes. rsleigh-cli does NOT
# depend back on root rsleigh, so the cycle is one-way and resolves by
# publishing rsleigh-cli first.
