feat(40): phase 2 — mint emits the DEED metadata block - #46
Conversation
Phase 2 of #40. Phase 1 shipped the compat reader; this converts the emitter, so `mint` now writes `@launcher-deed` instead of the retired `@a2ml-metadata` form. The compliance data is byte-identical either way — it is purely a dialect change — which is what makes the strongest available test possible: the new emitter's flattened output is asserted EQUAL to the committed pre-phase fixture's, field for field. templates/launcher.sh.tera The embedded block becomes a `praxis-deed` form, per the owner's ruling on the doc-head. Verified to contain no literal tab: `deed::parse` rejects a tab anywhere in the document, checked on the raw text before lexing, so a tab surviving into a value would not corrupt one field — it would make the whole block unparseable. crates/launcher-common/src/template.rs New `deedstr` Tera filter, the exact inverse of `deed.rs`'s `lex_string` and deliberately no stricter: the grammar admits exactly four escapes (\" \\ \n \t) and rejects other raw control characters below U+0020. U+007F is therefore ACCEPTED, because its consumer accepts it — a filter refusing it would ask a different question than the parser it feeds. CR has no legal spelling at all, so it is reported as an error rather than silently dropped: refusing to mint beats minting a launcher whose own metadata cannot be read back. Registered as a filter rather than pre-escaping the context so the escape applies at exactly the emission sites and every other interpolation in the script keeps its raw value. Tera autoescaping is HTML-shaped and does not fire for `.sh` regardless. crates/launcher/src/cmd_config.rs Dialect-naming strings corrected — the "no @a2ml-metadata block found" message named only the retired form while the reader accepts both. Module doc records that `set` refuses a DEED block by design. Three mutants killed, per the rule that a passing suite proves nothing until a mutant dies: A `deed_escape` made the identity function -> 4 tests red B emitter drops one compliance standard -> 1 test red (the paired control alone, proving it checks the DATA and not merely that two things parsed) C emitter reverts to the legacy markers -> 4 tests red Clean restore re-run: 72/72, so every red above is attributable to the mutant and not to ambient state.

The mirror of `minted-2026-09-22_stapeln-launcher.sh`, and it guards the other direction. That fixture proves a launcher minted BEFORE the dialect change still reads. This one will prove a launcher minted DURING it still reads after some later tightening of the DEED grammar: `deed::parse` is shared with the rest of the estate and will keep moving, while the launchers this emitter has already written will not. Without a committed artefact there is nothing to notice they had been stranded. Captured from the real emitter, not typed by hand. ⭐ Mutant D — the emitter's `:generator` string changed — was run specifically to check this test is not decorative, and it found something worth recording: a_launcher_minted_by_phase_two_reads_... FAILED (killed) a_launcher_minted_before_phase_two_... FAILED (killed) both_dialects_agree_on_what_todays_... ok <-- BLIND `both_dialects_agree` builds its legacy leg FROM the deed the emitter just produced, so under a uniform value change both legs move together and the equality still holds. It is structurally incapable of catching that class of change — which is not a defect in it (it exists to prove cross-dialect agreement, and it does) but it does mean the committed fixtures are the only thing anchoring the emitter to a known-good value set. That is the argument for this file existing. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01WPSJ7fBhVAMcpSffCBWUDo Signed-off-by: Jonathan D.A.

CodeRabbit's 8489eab fixed the stale `rewrite_scalar` diagnostic and added a test for it. This keeps that test and strengthens two things. `err.to_string()` returns only the outermost `anyhow` context, so the assertion would stop seeing the dialect names the moment a context layer is added above this one. `format!("{:#}", ...)` walks the whole chain, which is what `config set` callers actually read. The comment records a trap met while writing this: `DEED_BEGIN` is the whole marker line `# @launcher-deed begin`, not the bare dialect name, so asserting against the constants would assert a different question than the prose diagnostic answers. Verified: rustfmt 0 diffs, 84 tests pass, clippy 0 warnings, and the mutant dies — restoring the phase-1 wording fails exactly this test (72 passed / 1 failed) and nothing else.

Carries forward the one commit of #47 that is **not** already on `main`. ## Why this exists Four of #47's five commits landed via the #46 squash (`552ecf4`). Only `4cac602` carried content that is still absent from `main`, so rather than force-push over CodeRabbit's branch or discard the work, that single commit is cherry-picked here with `-x`. **Authorship is preserved** — the commit is still authored by `coderabbitai[bot]`; this session signs only as committer. ## What it changes Documentation only. No behaviour change, no test change. Two files, +12 -5. Every claim in the new doc comments was **verified against `main` at `552ecf4`** before being carried, rather than taken on the original PR's word: | documented error path | verified against | |---|---| | refuses the read-only DEED dialect | `if block.is_deed() { bail! }` | | `new_value` inserted verbatim, no escaping | `rewritten.push_str(new_value)` | | key absent, or names a list | the two `bail!`s above the scan | | parsed but not safely locatable | `if !patched { bail! }` | The pre-existing docstring named only two of those five error paths, so this is a **correctness fix to the documentation**, not a rewording. ## Verification - `cargo test --workspace` — **84 passed, 0 failed** (73 unit + 5 `deed_corpus` + 6 `round_trip`). - Subject line trimmed to 64 chars; the bot's original was 73, one over the estate's 72-char threshold. - Commit is signed (`%G?` = `G`).

Phase 2 of #40. Phase 1 shipped the compat reader; this converts the emitter, so
mintnow writes@launcher-deedinstead of the retired@a2ml-metadataform.Closes the emitter half of #40. Follows #43 (the pre-phase fixture), which this
change depends on and which made the strongest test here possible.
It is a pure dialect change, and that is what makes the test strong
The compliance data is byte-identical in both dialects. So the central test is
not "the new block parses" — it is that the new emitter's flattened output is
equal to the committed pre-phase fixture's, field for field:
A launcher minted today and one minted before the change carry the same values.
That is the compat promise, asserted against an artefact rather than a
reconstruction.
The escape filter is the exact inverse of its consumer, deliberately no stricter
deedstrwas written againstdeed.rs'slex_string, not against intuition:"\\n\t< U+0020< 0x20A filter rejecting U+007F would be stricter than the parser it feeds — the
estate's most-recurring trap, a guard asking a different question than its
consumer. CR is the opposite case: it has no legal spelling in a deed string
at all, so it is an error rather than a silent drop. Refusing to mint beats
minting a launcher whose own metadata cannot be read back.
⚠ The tab case reaches furthest.
deed::parserejects a literal HTAB anywherein the document, tested on the raw text before lexing — so a tab surviving into
a value would not corrupt one field, it would make the whole block unparseable.
The emitted template is verified to contain zero literal tabs.
Registered as a Tera filter rather than pre-escaping the context, so the escape
applies at exactly the emission sites and every other interpolation in the script
keeps its raw value. (Tera autoescaping is HTML-shaped and does not fire for
.shin any case — without this, a display name holding one"closes thestring early.)
:standards— measured, not assumedAn earlier review flagged that the emitted block claims compliance with
launcher-standard.adocwhile D73-C converted that standard to.deed, so afresh mint might fail AC4's currency gate. Measured instead:
docs/UX-standards/launcher-standard.adocexists onstandardsmain(it was the
.a2mlthat was deleted), as doesLM-LA-LIFECYCLE-STANDARD.adoc.scripts/check-launcher-standard-currency.sh:34-37states verbatim thatlauncher-standard.adocis "a DIFFERENT document (the human-readable UXstandard) and is deliberately NOT checked here."
launcher-standard_praxis.deedat0.4.0.So the block is correct as emitted and the gate exempts it by design. No change
needed, and no owner ruling required.
⚠
:schema-versionis the grammar version (1.0.0);:standard-versionisthe document version, read live from the real deed via
standard.rs:100-108— not hardcoded, and not interchangeable with the former.
config setnow refuses on freshly-minted launchers — by design, and owner-ruledcmd_setcallsrewrite_scalar, which declines to edit a DEED form in place.Phase 2 therefore changes observable CLI behaviour:
config sethard-fails onevery launcher minted from here on.
Put to the owner and ruled: leave it refusing. A deed block is a generated
artefact; in-place scalar surgery on it is how you get a launcher whose metadata
no longer parses. The config file stays the single source of truth and re-mint is
the only edit path. Zero new code — the refusal is already covered by a test.
cmd_config.rs's user-facing strings are corrected to match: the "no@a2ml-metadatablock found" message named only the retired dialect while thereader has accepted both since phase 1.
Four mutants killed
A passing suite proves nothing until a mutant dies.
deed_escapemade the identity function:generatorvalue⭐ Mutant D found something worth reporting.
both_dialects_agree_on_what_todays_emitter_producesstayed green under it, because it generates its legacy leg from the deed the
emitter just produced — so under a uniform value change both legs move together
and the equality still holds. It proves the transform, never the value. That is
not a defect (it exists to prove cross-dialect agreement, and it does), but it
means the committed fixtures are the only thing anchoring the emitter to a
known-good value set. Hence the second commit.
Two committed fixtures, one facing each way
minted-2026-09-22_stapeln-launcher.sh(legacy, from test(40): capture a launcher minted by today's mint as the pre-phase fixture #43) — proves a launcherminted before the change still reads. Not edited by this PR.
minted-2026-09-23_stapeln-launcher-deed.sh(new) — proves a launcher mintedduring it still reads after some later tightening of the DEED grammar.
deed::parseis shared with the estate and will keep moving; launchers alreadywritten will not.
Both captured from the real emitter, neither hand-typed, neither derived from the
other.
⚠ The two red phase-1 guards were inverted deliberately
round_trip.rscarriedphase_one_mint_emits_the_legacy_markers_and_not_the_deed_ones,whose own doc comment reads "Stated as a test rather than left to the diff, so
phase 2 has to delete this line deliberately." It did its job. Both it and
mint_parse_realign_parse_is_stable_for_the_legacy_formnow assert the phase-2contract, pointing the other way, so a revert has to delete them just as
deliberately.
Two further tests in that file had gone green-but-degenerate rather than red —
subtler, and easy to miss. Since
mint()now returns a deed, their variable namedlegacyheld a deed block, so "both dialects agree" was comparing deed againstdeed. The legs are inverted.
Verification
⚠
launch-scaffolderhas no Rust CI (#45) — six workflows, not one runscargo, so 18
.rsfiles and 59+#[test]fns have never executed in CI. Thelocal output above is the evidence for this PR, and that is a statement of what
is not proven here, not a claim of coverage.
Incidental: this also cures one pre-existing

app_licensechain) that was already red onmain, in a file this PR isediting anyway.
