Conversation
Settle the source to the 1.2.0 candidate and add the artifact-boundary proof tooling that R06's acceptance requires. Version 1.2.0 (SemVer minor: R04 added the backward-compatible public handle_slot_origin/2 callback). Cut the dated CHANGELOG [1.2.0] section and comparison links; README/ROADMAP describe 1.2.0 as a built, unpublished candidate (not published or tagged). Gates (red-before-green, mutation-proven): - test/release/release_contract_test.exs — version advances past the last published (1.1.0), matches the newest dated CHANGELOG section + comparison links, and pins docs source_ref. Watched RED at 1.1.0 before the bump. - scripts/release/verify_package.sh + package_files.manifest — the built tar's exact 51 regular files must equal the manifest (rejects any glob-matched ignored/untracked leak: README.secret / lib/.env / docs/adr/private-note.md all packaged while the old CI grep gate exited 0), no symlink/special entry, metadata name/version replicant/1.2.0. Red-proven on all four mutations. - test/release/public_surface_test.exs — semantic (not grep) R01-R05 surface: handle_slot_origin/2 + handle_session_identity/2 optional callbacks, the IDENTIFY_SYSTEM query, version-tiered slot-invalidation SQL, the value-free telemetry boundary (a leaked value REDs it — proven), and the R01 fault + absent-slot fail-closed :data_gap halt. Replaces the CI source greps. Build + consume the immutable artifact: - scripts/release/build_candidate.sh — builds ONE tar from `git archive HEAD` (not the checkout, so ignored/untracked files cannot contaminate it), runs the boundary gate, content-addresses + retains it read-only with a backup, and writes a gitignored receipt (version, source commit, mix.lock digest, size, SHA-256). Fail-closed identity-collision checks; never publishes/tags. - scripts/release/consume_candidate.sh (+ unpack_validated.exs, consumer_smoke.exs) — Hex-checksum-validated unpack of the exact retained tar (a tampered byte REDs it), a fresh external consumer compiled warnings-as-errors from only the extraction, provenance-checked to load Replicant from under scratch, then the R01-R05 public surface exercised from the artifact-derived modules. - scripts/release/upload_candidate.exs — guarded EXACT-BYTE uploader for R07 (hex_core :mix_hex_api_release.publish/3, replace:false), dry-run only here: verifies digest identity, Hex-validated metadata, source-commit, and no colliding tag/release, reads NO credential, uploads nothing. CI release-artifact job now runs the manifest gate, a build+consume, and the uploader dry-run in place of the required/forbidden-path greps. Ticket: #6. R06 never publishes, tags, or reads a credential; publication is R07 under separate human authorization naming version + digest.

Fail closed on every remote identity check, cryptographically witness the artifact receipt to its source commit, rehash all retained copies, verify the package from extracted bytes, and keep CI proof builds throwaway-only.
Remove the file-script argument separator that Mix forwards verbatim, and pin the invocation shape with a regression assertion.
After an authorized exact-byte upload, refetch the release metadata and require its checksum to equal the witnessed artifact before reporting success.
Reject symlink and writable inputs, read candidate evidence once, and carry the same immutable bytes through validation, authorization, upload, and checksum.

Inline comments:
In `@scripts/release/build_candidate.sh`:
- Around line 72-83: Add the .kimosabe/ directory to the repository’s .gitignore
so generated artifacts and receipts from the mint process are ignored and do not
make the working tree dirty on subsequent runs.
In `@scripts/release/consumer_smoke.exs`:
- Around line 11-13: Update the provenance check in the scratch-path validation
to require the prefix scratch <> "/" rather than scratch alone, ensuring only
paths inside the scratch directory pass while preserving the existing raise
behavior.
In `@scripts/release/package_identity.exs`:
- Around line 138-142: Update the private run/2 command execution flow to
enforce deadlines for git and curl using a process-lifecycle mechanism that
terminates the OS process when the timeout expires, rather than relying on
System.cmd/3 alone. Ensure curl arguments include both --connect-timeout and
--max-time, while preserving existing command output and exit-status handling.
In `@scripts/release/package_witness.exs`:
- Around line 80-88: Handle the result of IO.binwrite in the File.open branch
before calling File.chmod!, propagating or raising on {:error, reason} and only
making the destination read-only after a successful :ok write. Preserve the
existing file-close cleanup and exclusive-open behavior.
In `@scripts/release/unpack_validated.exs`:
- Around line 15-18: Update the successful unpack branch of
:mix_hex_tarball.unpack to require metadata containing a non-empty
:outer_checksum value instead of defaulting via Map.get. Preserve checksum
encoding and the existing OK output for valid metadata, while routing missing or
invalid checksum metadata to the error path so validation fails closed.
