Step 9 (convert tests to BAST format) was a no-op: steps 4-8 converted
the tests as they went. The only remaining reference in
src/tests was the intentional rejection test at
src/schema.rs:462 (asserting the old keyword form is rejected). Full
suite passes: 389 tests (312 lib + 77 integration).
Step 10 (sync architecture docs and ADRs):
Descriptive docs rewritten/updated for BAST:
- schema-layer.md: rewritten for the BAST parser (BastDoc/BastDef/
BastType typed tree, AlkTypeKind enum with to_bast_str/from_bast_str,
what was removed). Points at bast-format.md for the normative format.
- validation.md: rewritten for the two-validator model
(bast_validation for validate_bytes, standard jsonschema for
validate_json). Documents the repurposed build_validator, the
AlkTypeError::Validation uniform payload (D-BAST-009), and what is
removed.
- builder.md: updated all output examples to BAST JSON
(struct_() -> { kind: struct, fields: [...] }; object() -> standard
JSON Schema). Documents build_doc, count(), and the field-name union
fields requirement (D-BAST-005).
- overview.md: updated for BAST (what/why, schema-is-the-format table,
dependencies, architecture pointers, design decisions table).
- README.md (architecture index): updated document table, ADR table
(new ADR-BAST + ADR-VAL-SPLIT, superseded ADR-001), OQ table
(OQ-007/OQ-008 resolutions updated for BAST-native validator), and
key design principles (#1, #2, #7, #10 reworded for BAST).
- data-access.md: updated tunion function signatures to BastUnion and
the variant resolution to return BastType (resolve_typeref for refs).
- layout-engine.md: updated construct signatures
(LayoutBuilder::new(bast_doc, root_name), OffsetMap::compute(&doc),
SequentialReader::new(bast_doc, root_name)), the recursive-walk
description (BAST typed tree), and composite-kind headings
(TStruct/TUnion/TArray -> struct/union/array). Added D-BAST-004
note on array count requirement.
New ADRs:
- ADR-BAST (bast-bast-format.md): the BAST format, meta-schema,
//kind vocabulary, design principles, what is removed, the
enum index bounds bug fix. Supersedes ADR-001's format-specific
content; records D-BAST-001..009.
- ADR-VAL-SPLIT (val-split-two-validator-model.md): the two-validator
model (BAST-native for validate_bytes, standard jsonschema for
validate_json), the repurposed build_validator, the uniform
AlkTypeError::Validation payload. Refines ADR-004's validation
strategy and ADR-010's validation step; records D-BAST-006/007/009.
Amended ADRs (supersession/amendment notes added; original decision
text preserved as historical record):
- ADR-001: format-specific content superseded by ADR-BAST;
purpose/scope and schema-is-the-format principle retained.
- ADR-002: unchanged under the pivot; one-line note that the input
format changed but the modes didn't.
- ADR-003: annotation semantics retained; annotation location moved
to BAST type-level properties (amended by ADR-BAST).
- ADR-004: AlkTypeError enum retained (D-BAST-009); validation
strategy section refined by ADR-VAL-SPLIT.
- ADR-009: builder API surface retained; build() output format
amended to BAST / standard JSON Schema by ADR-BAST (D-BAST-008).
- ADR-010: validate_bytes two-step concept retained; validation step
amended to the BAST-native validator by ADR-VAL-SPLIT.
Other:
- Cargo.toml description: JSON Schema with AlkType:* custom keywords
-> BAST document.
- bast-pivot.md research record: status draft -> implemented, with a
pointer to the ADRs that superseded its decisions.
- bast-implementation.md plan: status draft -> complete, with a note
that step 9 was a no-op and step 10 is this commit.
- open-questions.md: OQ-006/OQ-007/OQ-008 resolutions updated for the
BAST-native validator.
- questions/008-unionvalidator-variant-dispatch.md: added a
post-BAST-pivot note pointing to the current bast_validation
implementation; v0.1.0 resolution text preserved as historical
record.
Verification:
- cargo test --release: 389 pass (312 lib + 77 integration)
- cargo clippy --all-targets -- -D warnings: clean
- cargo doc --no-deps: clean
- cross-reference check: every relative link in the new/updated docs
resolves (verified by script).
The bast-pivot.md research doc had grown to 1477 lines (~58KB) through
iterative editing, pushing its most actionable content (D-BAST
decisions, POC result, migration steps) past the 50KB Read tool cap.
Agents peeking at the truncated file landed in duplicated/out-of-order
sections. Decompose into three readable-sized files with distinct roles:
- docs/architecture/bast-format.md (28KB, new): the normative BAST
format spec -- meta-schema, TypeRef, examples, validation model.
Grounded in the POC and D-BAST-001..009. Stable and safe to write
now; schema-layer.md/validation.md stay describing current code and
are rewritten post-implementation (per AGENTS.md ADR-grounding rule).
- docs/plans/bast-implementation.md (31KB, new): the execution entry
point -- ordered 10-step plan with per-step goal/files/spec-ref/
verification, the public-API semver contract table up front as a
scope-creep guardrail, and the ADR-sync checklist at the end. Each
step links to the specific bast-format.md section and D-BAST anchor.
- docs/research/bast-pivot.md (28KB, trimmed): now the research record
only -- Summary, Motivation, POC scope/result, Decisions, Risks,
References. The normative format spec, what-changes tables,
validator-split details, and migration steps moved to the two new
docs; pointers added. 1155 lines removed, 216 added.
- docs/architecture/README.md: index updated to list bast-format.md
and the two in-progress pivot docs, with notes on schema-layer.md
and validation.md being rewritten when the pivot lands.
All three files are under the 50KB Read cap, so an implementing agent
gets the whole document in one call. Cross-reference anchors verified
to resolve. No code changes; cargo test --release (396 tests) green.
Verification: cargo test --release (310 crate + 86 integration, all pass).
Four open questions were scattered inline in builder.md and the POC
findings doc. Moved them into the central OQ tracker under
docs/architecture/questions/ and updated the index:
- OQ-004: Discriminator::Field name type (&str vs String) — raised in
builder.md during ADR-009 spec drafting
- OQ-005: Union materialization shape (byte-offset vs field-name
consistency) — raised in the POC findings
- OQ-006: Builder spec Example 3 wrap Union in Struct — raised in the
POC findings (doc fix; engine requires AlkType:Struct at top level)
- OQ-007: Bytes materialization lossy UTF-8 — raised in the POC
findings (blocks SFTP use case for validate_bytes)
Index updates:
- open-questions.md: new 'Schema Construction' and 'Validation' theme
groups; new 'Open' section for active investigation targets (distinct
from 'Deferred / Blocked' which holds scope-parked OQs)
- README.md: OQ table extended with OQ-004 through OQ-007
- builder.md: inline OQ-004 replaced with a tracker reference
- findings.md: inline OQ-005/006/007 replaced with tracker references
Doc-only change; 369 tests pass.
Rename all 19 JSON Schema custom keyword strings from "TypeDef:*"
to "AlkType:*" (e.g., "TypeDef:Struct" -> "AlkType:Struct")
across source, tests, and docs. This is a breaking change to the
schema format itself — existing schemas using the old keywords
must be updated.
Rename the Rust identifiers:
- TypedefEngine -> AlkTypeEngine
- TypedefError -> AlkTypeError
- TypeDefKind -> AlkTypeKind
- TYPEDEF_PREFIX -> ALKTYPE_PREFIX
- get_typedef_kind{,_loose,_loose_enum,_enum} ->
get_alktype_kind{,_loose,_loose_enum,_enum}
Update error message strings ("unknown TypeDef kind" ->
"unknown AlkType kind"), 11 test function names containing
typedef_kind/to_typedef_error, and doc-comment prose ("TypeDef
kind" -> "AlkType kind", "typedef engine" -> "alktype
engine", "typedef schema" -> "alktype schema"). Fix the broken
docs/architecture/crates/typedef/ path references in source doc
comments to point at docs/architecture/ directly. Rebrand the
typedef:annotation test fixture and the "not-a-typedef" test
string to their alktype equivalents.
Update ~20 generic "typedef" prose references in the architecture
docs ("typedef is the binary struct engine", "use typedef",
"typedef limitation", "replaced by typedef", etc.) to alktype.
Rename TypedefEngine in the ADR-007 code example to AlkTypeEngine.
Preserve as provenance per the prior prose-rebrand decision:
typedef.ts references (external TypeBox source file),
docs/research/alknet-typedef/findings.md research citations,
/workspace/alknet-typedef-poc/ POC path, and the
"alknet-typedef:" research section headers in findings.
Build, 295 tests, and clippy all pass clean.
Renumber ADRs 095-102 to 001-008 and OQs 069-071 to 001-003, and
update all cross-references (titles, body prose, file-path links,
tables) across the 5 spec docs, README, open-questions index, and
all 11 ADR/OQ files. Inline the ADR-009 door-type definition from
the parent alknet project (broken cross-project reference).
Rebrand prose: alknet-typedef -> alktype in headings, body text,
dependency diagrams, and "additions" notes. Disambiguate the prior
failed attempt at /workspace/@alkimiadev/alktype/ as "the
@alkimiadev/alktype prototype" to distinguish it from this crate.
Historical research citations (docs/research/*, /workspace/alknet-typedef-poc/)
are kept as-is for provenance.
Rename the crate in Cargo.toml ([package].name, [lib].name) and
update the 11 use alknet_typedef::* imports across the 4 test files.
Rebrand the crate-level doc comment in src/lib.rs.
The TypeDef:* keyword strings, TypedefError/TypedefEngine identifiers,
and other code-level references are unchanged — those are a separate
code rebrand pass.
Build, 295 tests, and clippy all pass clean.
Copy the binary struct engine (src/, tests/) verbatim from
alknet/crates/alknet-typedef and create a standalone Cargo.toml
(workspace-inherited fields inlined). Port the architecture docs
(specs, ADRs 095-102, OQs 069-071) from alknet's nested multi-crate
layout to a flat single-crate layout, fixing relative link paths.
Build, 295 tests, and clippy all pass clean.
