From 1250e2be3d53602f31ed2b49a54adb7690854017 Mon Sep 17 00:00:00 2001 From: hyperpolymath <6759885+hyperpolymath@users.noreply.github.com> Date: Fri, 25 Sep 2026 21:33:41 +0000 Subject: [PATCH 1/6] fix(48): keep launcher pid and log files out of world-writable /tmp MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A minted launcher defaulted to `/tmp/-server.pid` and `/tmp/-server.log`. `/tmp` is world-writable and, on most distributions, not guaranteed to be cleared only of its owner's files, so the default put a predictable, pre-creatable path in a directory every user on the host can write. Hypatia's patrols 82 and 83 are the two findings this closes. Defaults now resolve per user, in the shell, at the point of use: PID_FILE="${XDG_RUNTIME_DIR:-${XDG_STATE_HOME:-$HOME/.local/state}}/..." LOG_FILE="${XDG_STATE_HOME:-$HOME/.local/state}/..." The PID prefers `$XDG_RUNTIME_DIR` because it is the one XDG base directory with a defined lifetime and documented 0700 permissions; the log falls to `$XDG_STATE_HOME` because a log outlives the session a runtime directory describes. Resolution is left to the shell rather than computed in Rust so the generated script stays portable to hosts where those variables are set by pam_systemd after login — a path baked in at mint time would be stale on the next boot. An explicit `pid_file` / `log_file` in the `[runtime]` block still wins, unchanged, including its `~` expansion. The launcher now creates those directories itself: `ensure_state_dirs()` runs as the first statement of `start_server()`, `mkdir -p`s both dirnames, and `chmod 0700`s them. Ordering matters — a directory created after the pid file is written is no protection at all — so a test pins `ensure_state_dirs` ahead of the first write to `$LOG_FILE` rather than merely asserting both appear somewhere in the script. `mkdir -p -m` was deliberately not used: with `-p`, the mode applies only to the deepest directory created. Tests pin the emitted `PID_FILE=` and `LOG_FILE=` lines as literals rather than recomputing them with `format!`, so a future "tidy-up" of the default expression has to edit the expectation instead of being confirmed by the same expression it changed. Verified: `cargo test --all-targets` 90 passing (74 before, floor 59), `cargo fmt --all -- --check` clean, `cargo clippy --offline --all-targets -- -D warnings` clean. The currency-locked fixture was re-minted with the built binary per `fixtures/metadata_block/README.adoc`; the frozen 2026-09-22 artefact was not touched.

It demanded three keys the standard has never asked for, and it accepted a block missing four the standard does require. Both halves are settled here. == The three keys that were not in the standard `runtime-kind`, `standard-spec-version` and `generator` are demoted to `ADVISORY_SCALAR_KEYS`. They are facts about the generator and the run, not about the launcher's contract with the estate, and requiring them is precisely what made a conformant launcher read as broken: `hyperpolymath/trigger`'s launcher carries all eleven fields the standard requires and none of these three, so every release of this tool has called it invalid while the standard called it conformant. `mint` keeps emitting them — they are useful provenance and every existing launcher carries them — but their absence no longer fails the guard. A requirement belongs in the standard, not in a parser. == The four keys that were in the standard `app-url`, `standards-compliance`, `modes`, `platforms` and the two lifecycle-phase lists are now checked. `standards-compliance` is a LIST, so `missing_required` looks at list keys as well as scalars; a scalar-only check could never have found it missing, which made the requirement unfalsifiable as written. The four declarations the emitter never made are now emitted. Their values come from the standard, not from the template: `platforms` and the two lifecycle lists are read out of new `(platforms …)` and `(lifecycle-phases …)` clauses, so the vocabulary is named once for the estate rather than invented per launcher. `modes` is the launcher's own surface — the arms of the generated script's main switch — and is pinned to that switch in both directions: a declared mode with no arm, or an arm with no declaration, fails. ⚠ Finding, not fixed here: the standard's `(required-modes)` also lists `--version`, which the generated script does not implement. That is a genuine gap between the launcher and the standard and is recorded rather than papered over by copying the standard's list into the block. == The encoding is now part of the requirement Until now the block's delimiters and field syntax lived only in `metadata_block.rs`, so a launcher could satisfy every requirement in the standard and still be unreadable by the tool the standard names as its consumer — `hyperpolymath/trigger`'s launcher carries all eleven fields in a `key: value` dialect with no markers at all. The standard now declares `(metadata-block (encoding …))`: both marker pairs (including the retired one, which is what keeps pre-2026-09-23 launchers readable), the comment prefix, the document head, and the field syntax. The parser's constants are asserted equal to the declared strings, and a block built from the deed's own declared encoding is asserted to parse. == Non-vacuity, measured not assumed * `required_keys_are_exactly_the_standard_required_fields` is an equality over two files; alone it is a tautology with extra steps, so `the_old_guard_passed_a_block_missing_four_required_fields` shows the committed 2026-09-22 artefact satisfying the OLD list (kept as a literal) while failing the new one. That contradiction is the defect. * Mutants killed: reverting `REQUIRED_SCALAR_KEYS` to the old list → 1 failure; editing the deed's `:marker-begin` → 1 failure; removing the four `push_list` calls → 6 failures. * `the_three_keysthat_are_not_in_the_standard_are_advisory` strips each advisory key from a complete block and asserts the result still reads as conformant — and asserts the key really is gone, so the strip cannot silently stop stripping. == The vendored standard now differs from canon `standards/launcher-standard_praxis.deed` carries three clauses canon does not have yet (the two value domains and the encoding clause). The content-hash pin that guards against accidental drift was updated in the same commit, and its doc comment records the divergence and why; upstreaming to `hyperpolymath/standards` is pending. Verified: `cargo test --all-targets` 98 passing (was 90), `cargo fmt --all -- --check` clean, `cargo clippy --offline --all-targets -- -D warnings` clean. The currency-locked fixture was re-minted with the built binary; the frozen 2026-09-22 artefact was not touched, and its four missing fields are now asserted by name in the fixture README.
