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 1/8] 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.

From f985bbb9d5dd712a57826f721060c59c938cd90f Mon Sep 17 00:00:00 2001 From: hyperpolymath <6759885+hyperpolymath@users.noreply.github.com> Date: Fri, 25 Sep 2026 21:58:36 +0000 Subject: [PATCH 8/8] docs(42): rule the per-app descriptor form, with its conformance pair MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The owner ruled migrate to `.deed` (standards#960 AC2). This is the design work that ruling creates. It moves no files. == Ruling 1 — filename: Arm B, `.launcher_praxis.deed` Deed filenames are a normatively closed production (`deed.abnf:66-71`), and the doc-head must match the filename dispatch (`:50-56`), so `.launcher.deed` is not a deed. A stem may contain dots (`deed.abnf:62-64,71`), so `stapeln.launcher_praxis.deed` is legal with stem `stapeln.launcher`, dispatching to `praxis-deed` — a suffix swap that keeps the `.launcher` infix every discovery pattern already knows. `praxis-deed` is also the right head: the stem→head table makes it the verb, *what a tool DOES*, and a per-app descriptor states what the launcher does for that app; it composes with `launcher-standard_praxis.deed` as the same head at two scopes. Arm A would cost six sites across three repos plus an owner ruling for a fifth document *form* that #41's work shows is not needed; arm C is a noun and loses the infix. == Ruling 2 — beholding: `#u5"estate/chora"`, named once A praxis deed requires `:beholding-chora` as a uuid5, and the one-declaration-site rule says a tool may not declare its own vocabulary. No launcher chora has been declared, so naming one would be the exact failure the spec exists to stop; the descriptors draw on the same vocabulary as the standard they conform to, which already beholds `estate/chora`. The trigger to revisit is recorded so this is one decision rather than 21. == Ruling 3 — the field vocabulary, named once Derived from `config.rs`, which is the only schema a per-app descriptor has today. Every TOML key gets a deed spelling: `(project …)`, `(repo …)`, `(runtime …)`, `(icon …)`, `(soft-attach …)` and `(compliance :standard-version "0.4.0")` — the last separated from `:schema-version` on purpose, because the grammar version and the document version are different numbers and conflating them makes a stale document read as a newer spec. Four findings are recorded rather than dropped: `[integration]` and `[exceptions]` have no schema (both are `toml::Value`), and the `[[exceptions.override]]` array-of-tables is proposed as repeated `(override …)` clauses; no UUIDs appear today, so the uuid5-only rule costs nothing; and three things TOML permits — `=`, `[section]`, tabs — are invalid in a deed, which matters because `[integration]` and `[exceptions]` are untyped and must be scanned, not assumed. == Conformance pair, and why it is not in fixtures/deed/ That corpus is manifest-locked: `MANIFEST.sha256` asserts set equality between what is vendored and what is on disk, so files cannot be added without a refresh from `standards`. The pair — one valid, two invalid — lands in `tests/fixtures/per_app_deed/` under `tests/per_app_deed.rs`, which also makes the vocabulary executable: every clause and field the document names is asserted reachable through the reader. Rejections pin a message fragment, so a fixture cannot pass on an accidental failure. Mutant killed: deleting the tab from the tab fixture makes the document parse, which is the proof that the tab is what makes it invalid. == Dry-run manifest `realign --dry-run` already exists and is named as the generator. Both descriptors in this repository are listed with their proposed paths, with the warning that renaming either re-mints the committed launcher artefacts, whose input path is load-bearing. == Still open AC5 — a reader and a canonical writer, with a byte-identical round-trip — is not implemented here. It needs a writer as much as a reader, and this vocabulary is its input. F1/F2 need the launcher standard to specify `[integration]` and `[exceptions]`; upstreaming the conformance trio to `standards` is follow-up. Verified: 103 tests passing (was 98), `cargo fmt --all -- --check` clean, `cargo clippy --offline --all-targets -- -D warnings` clean.

Nothing here +is a bulk pass. + +--- + +== Ruling 1 — the filename is Arm B: `.launcher_praxis.deed` + +*Deed filenames are a normatively closed production* (`deed.abnf:66-71`): +`estate-file / atlas-file / praxis-file / repo-file`, with a semantic +constraint at `:50-56` — **the doc-head MUST match the filename dispatch, +and a mismatch is a validation error.** `.launcher.deed`, matching none +of the four, is not a deed. + +[cols="1,4",options="header"] +|=== +|Arm |Ruling + +|**B — `.launcher_praxis.deed`** +|**CHOSEN.** A stem may contain dots: `deed.abnf:71` admits `.`, and +`deed.abnf:62-64` says so explicitly — *"Do NOT split on `.` — the stem may +contain dots."* So `stapeln.launcher_praxis.deed` is a legal deed filename +with stem `stapeln.launcher`, dispatching to `praxis-deed`. The rename is a +suffix swap, `.launcher.a2ml` → `.launcher_praxis.deed`, and the existing +`.launcher` infix survives, so no discovery pattern in the estate has to +learn a new stem shape. The head is also the right one: the stem→head table +(`DEED-GRAMMAR-SPEC.adoc:276-295`) makes `praxis-deed` the *verb* — *what a +tool DOES* — and a per-app descriptor states what the launcher does for that +app. It composes with what already ships: `launcher-standard_praxis.deed` +states the general rules; `.launcher_praxis.deed` states that app's +conforming praxis. Same head, two scopes. + +|A — add a fifth head `launcher-deed` +|Rejected. Honest cost is **six sites across three repos** plus an owner +ruling — every existing head is an owner ruling, and `praxis-deed` was ruled +a genuine fourth head, not a facet of `repo-deed`, on standards#752 +(2026-09-08). Arm A is justified only if a launcher descriptor is a fifth +document *form* rather than a praxis document, and after #41's work the +descriptor's substance reads as exactly that: rules for one app's launcher, +drawn from the same vocabulary as the standard. Arm A also makes +`DOC_HEADS: [&str; 4]` in this repo a typed change and every other site a +silent one. The burden is not met. + +|C — `_chora.deed` +|Rejected as semantically wrong, and recorded so it is not rediscovered. +`repo-deed` is *"What a repo IS — a record"*, a noun. A launcher descriptor +is not a record of what a repo is. It also discards the `.launcher` infix +that Arm B keeps for free. +|=== + +*Consequence in this repo:* `discovery::is_live_config` and its +`LIVE_EXT` / `FIXTURE_EXT` constants learn the new extension; +`deed.rs::DOC_HEADS` does **not** change, because `praxis-deed` is already in +the closed set. + +== Ruling 2 — beholding: `#u5"estate/chora"`, named once + +A praxis deed **requires** `:schema-version`, `:canonical-name` and +`:beholding-chora`, and the last must be a **uuid5**, never a bare filename +(`DEED-GRAMMAR-SPEC.adoc:379-414`; the one-declaration-site rule at +`:398-400` and `:420-433` — *a tool may not declare its own vocabulary*). + +**Ruled: every converted descriptor beholds `#u5"estate/chora"`.** + +The reason is the rule itself. No launcher-specific vocabulary has been +declared by the chora; writing `#u5"estate/chora/launcher"` because it reads +well would be a tool naming its own chora — the precise failure the spec +exists to stop. `launcher-standard_praxis.deed` already beholds +`#u5"estate/chora"`, and the per-app descriptors draw on exactly that +vocabulary, so they behold the same chora the document they conform to +beholds. + +*Trigger to revisit, so this is one decision and not 21:* when the estate +chora declares a launcher vocabulary, all 21 descriptors switch in a single +change. The field appears in N files; the vocabulary is declared in one. +Until then, `estate/chora` is the only honest answer. + +This repo's `deed.rs` carries the uuid5 **name** and derives no digest — +nothing in `launch-scaffolder` needs it — so `#u5"estate/chora"` is stored +verbatim and compared verbatim. + +== Ruling 3 — the field vocabulary, named once + +The praxis field set beyond the required three is formally provisional: the +spec warns that the owner ruled the head but not the fields, and that +inventing them is the failure the document exists to stop. There is working +precedent in the very file D73-C shipped — `launcher-standard_praxis.deed` +carries `:standard-version`, `:standard-date` and `:compliance` beyond the +three — so the practical question is *which fields, named once, for all 21*. + +The vocabulary below is derived from `crates/launcher-common/src/config.rs`, +which is the only schema a per-app descriptor has today.

Repetition is the +deed spelling of a list of records, and it preserves order. Recorded as the +proposed shape, pending the same standard-side specification as F1. + +**F3 — no UUIDs appear in any descriptor today**, so the uuid5-only rule +costs the conversion nothing. Recorded because it is the kind of constraint +that only surfaces mid-migration. + +**F4 — the grammar forbids three things the current files may contain:** +`=` as a separator, `[section]` headers, and **tabs as separators**. Only +four escapes are legal: `\"`, `\\`, `\n`, `\t` — `\r` and `\uXXXX` are +invalid. Booleans are `#t` / `#f`, never `true` / `false`. None of these +occur in `config.rs`'s typed surface, but `[integration]` and `[exceptions]` +are untyped, so the conversion pass must scan them rather than assume. + +== Conformance fixtures + +The vendored corpus under `tests/fixtures/deed/` is **manifest-locked**: +`MANIFEST.sha256` asserts set equality between what is vendored and what is +recorded, so files cannot be added there without refreshing it from +`standards`.
