Resolve N2: bound align annotations at 4096 (review #006)
align: 2^62 compiled and reported total_size = 2^63 — meaningless layout output the consumer may act on, and the reachable path to the MAX_ARRAY_BYTES cap used exactly this knob. - MAX_ALIGN = 4096 (page granularity) in schema.rs, documented with the probe arithmetic - parse_align returns Result and rejects over-cap values with a clean Schema error naming path/value/maximum — a silent clamp was rejected (it would change layout semantics without telling the consumer); both call sites thread the path, so standalone BastDoc::new (which never runs the meta-schema) is covered - Meta-schema: "maximum": 4096 on StructDef.align and FieldDef.align — the published alk.dev/bast/v1/schema contract now matches the parser - H1's byte-cap test retuned to align 4096 x count 2^16 = 2^28 > 2^26 (the byte cap stays reachable under the new align cap) Tests: 3 new (struct align above cap, field align above cap, align at cap accepted). 511 tests green, clippy -D warnings clean, wasm32 build green, cargo doc zero warnings. |

Resolve L2/L3: real schema threaded through ReadPlan compile; dead locals dropped (review #006)
L2: compile() builds Arc<Value> once and threads &Arc<Value> down the compile walk; every real ReadPlan carries the document at construction — the Value::Null-placeholder-then-map-overwrite dance is gone. The one remaining Null in wrap_leaf is documented as correct-by-construction (anonymous synthetic wrapper, never escapes). L3: materialize_plan_field drops its plan parameter (taken solely to discard) and the field-disc union arm's disc_field/let _ pair is deleted — the order-walk + by-name capture is the materializer's correct design, as the finding's parity note described. 508 tests green, clippy -D warnings clean, wasm32 build green, cargo doc zero warnings. |

Fix M1/M2/M3: ADR-006 record gap + aligned record coverage + dead Struct arm (review #006)
M1: field_variable_kind (offset_map) now matches Record — a non-final inline length-prefixed record field in aligned mode hits the ADR-006 rejection instead of computing silently corrupt offsets (probe-verified clobber in the review: counts prefix at 0, id at 4). M2: aligned record path locked with public-path tests — materialize_aligned roundtrip (record<uint16>, wire arithmetic asserted) and engine validate_bytes roundtrip + corrupted-buffer rejection (record<uint32>). Record-as-last-field is the only safe inline position post-M1. M3: read_field's unreachable Struct arm (no struct-path entry ever exists in an OffsetMap) replaced with a documented defensive Offset error; doc comment states struct paths have no entry and the Offset miss is the reachable composite failure. FieldValue::Struct (public API, constructed by the packed reader) untouched. Tests: 7 new (2 offset_map, 2 materialize, 1 engine M3 lock, plus the roundtrip pair). 508 tests green, clippy -D warnings clean, wasm32 build green, cargo doc zero warnings. |

Fix H2: shared reference-graph guard for standalone walkers (review #006)
Cyclic or over-deep $ref graphs stack-overflowed the three standalone schema walkers (OffsetMap::compute, LayoutBuilder::new, materialize_aligned) — SIGABRT on probe, parity-preserved from 0.2.0. - New src/walk_guard.rs: check_ref_graph() — one bounded walk over the reachable reference graph (depth cap 128 matching the plan compilers, path-scoped cycle set; diamonds allowed, cycles and 201-def chains rejected with the plan compilers' error wording) - All three walkers run the guard at entry, before any recursion; materialize_aligned's is defense-in-depth (a cyclic doc can no longer produce an OffsetMap, but mismatched doc/map inputs must still fail cleanly) - Behavioral side effect, net-positive: the guard eagerly parses every reachable def, so an invalid non-root def now surfaces at LayoutBuilder::new instead of build() — four H3 tests updated to expect the same Schema error earlier - Test family: 12 new tests (walk_guard, offset_map, layout_builder, materialize) covering self/two-def/composite-carrier cycles, deep chains, and diamond non-rejection; no stack-overflow reproducers in-tree per the review's Methodology warning - Stale "walkers have no cycle guard" statements updated in validation.md, 030 plan, ADR-012, and the engine gate comment Verified: 501 tests green (423 + 17 + 34 + 15 + 12 + 2 ignored), clippy -D warnings clean, wasm32 build green, cargo doc zero warnings. |

Fix H3: field-disc union wire convention — shared-then-variant (review #006)
Decision (recorded as an ADR-011 addendum): the packed-mode wire layout for a field-name-discriminator TUnion is shared-then-variant — the union's declared `fields` (disc + shared fields) first, then the variant's own fields. Reader and materializer already implemented this; LayoutBuilder was corrected from variant-only layout. Enforcement in BastUnion::parse (the choke point every consumer inherits — union roots at BastDoc::new, referenced unions at resolve_ref): - discriminator field must be declared in `fields` - `fields` must not contain duplicate names - variants must not re-declare shared fields (checked inline and through $ref resolution — parse chain now threads the doc root) - the discriminator field must be the FIRST entry in `fields` (the reader reads the disc at the union start; a later position made it dispatch on the wrong bytes — H3 item 2, probe-verified) Schemas relying on the old variant-only builder convention (variants re-declaring shared fields) are rejected with a clean Schema error naming the convention. Breaking for 0.2.0-era re-declaring schemas; announced with 0.3.x. - L5: FieldValue::Union::variant_start doc now states per-kind semantics (byte-disc: union_start + disc.offset + disc.size; field-disc: after the shared walk). - L6: roundtrip test added (poc_roundtrip.rs) — LayoutBuilder write → SequentialReader read → materialize_packed → validate_bytes over a field-disc union with a second shared field and non-redeclaring variant; pins event.type@0/seq@1/handle@5, total 10. - ADR-011: Status-block addendum recording the convention decision, the no-re-declare rule, and the breaking-constraint note. - Review #006 updated: H3/L5/L6 resolution blocks, resolution log, recommended order. Verified: 488 tests green (410+17+34+15+12, 2 pre-existing ignored), clippy -D warnings clean, wasm32 build green, cargo doc zero warnings. |

Fix H1: bound untrusted array counts; resolve L1 (review #006)
- Replace the three Vec::with_capacity(count) sites in materialize.rs with Vec::new() — validate_bytes on an adversarial count no longer OOM-aborts the process (AGENTS.md §3). - New compile-time caps in schema.rs: MAX_ARRAY_ELEMENTS (2^16, enforced at BastArray::parse — the choke point every consumer inherits, bounds the walkers' per-element entry loops) and MAX_ARRAY_BYTES (2^26, enforced per walker against the mode-specific stride: compile_array, walk_array, compute_array_field). - L1: fixed_composite_size/fixed_plan_size now return Result<Option<usize>>; unwrap_or_default() gone, overflow is a clean Schema error instead of silent stride-0. - Zero-progress guard: stride-0 arrays whose elements consume 0 bytes (legal empty-struct elements) now error in plan_walk_variable_array_ size and materialize_array_packed instead of looping count times. - Tests: 8 new (parse/build/compile rejections, cap boundary, short-buffer clean error) + array_count_large_u64_parses_on_64bit rewritten to assert the new cap rejection. In-tree tests assert only the safe (compile-time) half per review #006's Methodology warning. - Review #006 updated: H1/L1 resolution blocks, new finding N2 (unbounded align annotations, found while re-deriving the cap arithmetic), resolution log, recommended order.

Add review #006: 0.3.0 post-implementation review
Audits the shipped 0.3.0 code (commits ff85258..9949f91) for correctness, untrusted-input discipline, 0.2.0 parity, code smells, and coverage. Gates re-run green in-session (474 tests, clippy -D warnings, doc, wasm32, publish --dry-run); coverage measured with cargo-llvm-cov (89.59% lines / 84.80% fn). Findings: - H1: huge declared array count OOM-aborts validate_bytes (three Vec::with_capacity(count) sites; release-blocking) - H2: cyclic $ref stack-overflows OffsetMap::compute / LayoutBuilder::new / materialize_aligned when driven standalone (engine gated, public walkers not; parity-preserved) - H3: field-disc unions — builder (variant-only layout), reader (disc at union start), and materializer (position-correct shared walk) disagree on layout and discriminator position; needs a convention decision - M1: ADR-006 check misses non-final inline Record fields (probe- confirmed) - M2: aligned-mode record fields untested end-to-end - M3: read_field's aligned Struct arm is unreachable dead code - M4: coverage weak spots (materialize.rs 64.5% lines; aligned nested-struct recursion 0 executions through any test) - L1-L6, N1: stride unwrap_or_default conflation, Null-schema placeholder, dead locals, linear-scan get, variant_start doc gap, missing field-disc roundtrip test, tunion/reader disc-kind split Includes an operational warning: the H1/H2 reproducers OOM/stack- abort the test harness — reproduce in an isolated process only.

Release v0.3.0: compiled forms — ReadPlan, owned BastDoc, LeafMeta, ValidationPlan, fingerprinting
Public API bump 0.2.0 -> 0.3.0 (the 030-compiled-forms plan is now fully implemented; all eight phases landed). - Cargo.toml: version 0.3.0. lib.rs re-exports complete (ReadPlan + sub-types, LeafMeta, OffsetEntry, ValidationPlan + sub-types). - ADR-007 "Cost" rewritten to the Arc<ReadPlan> cost (15.7 ns) with the 0.2.0 "re-parse on demand" framing as a historical note (review #004 L2, the last loose end from that review). - ADR-011/012 status blocks flipped to implemented; architecture README ADR table rows updated; layout-engine.md rewritten for the 0.3.0 surface (engine-factory reader construction, OffsetMap OffsetEntry/LeafMeta/fingerprint section, owned BastDoc compute signature); SequentialReader module doc points at the engine factory. Reviews #004 and #005 flipped to closed. - Bench re-run (alktty wire_vs_bast, 0.3.0 tree): read p64 98 ns/chunk (parity with phase 2; hand-rolled 5.7 us/stream), layout_build 180 ns (was ~1.2 us — the phase-4 owned-doc cache removed the per-build re-parse, ~7x), sequential_reader_new 15.7 ns, write p64 -3%, engine_compile unchanged (meta-schema validation dominates). No dedicated validate_bytes-stream bench: the phase-7 spot check (~0.2 us plan-validate vs ~0.6 us compile-per-call) stands; a dedicated bench is a follow-up if alkcall profiling motivates it. - Downstream: alktty compiles against the path dep unchanged; alkcall has no dependency yet. Verification (full block, all green): 474 tests; clippy -D warnings clean; cargo doc zero warnings; wasm32 release build green; cargo publish --dry-run clean at 0.3.0. |

Fingerprint ReadPlan/OffsetMap: Hash + Eq + fingerprint() (ADR-012 §1/§4, plan phase 6)
- #[derive(Hash, Eq)] on ReadPlan, FieldPlan, CompositePlan, ReadKind, DiscriminatorPlan (schema: Arc<Value> hashes via serde_json Value Hash + Eq under preserve_order), and on OffsetMap (+ Clone; LeafMeta/OffsetEntry/ByteRange payload already Hash from phase 5 / this phase). - fingerprint() -> u64 on both via std DefaultHasher (deferred decision 3 resolved: no new dep, not hot, cross-version stability a non-goal per ADR-012). - Contract tests both sides: equal schemas -> equal PartialEq + fingerprint; field-kind / field-order / endianness changes each break equality and fingerprint; different root names over the same document fingerprint differently (ReadPlan). - ValidationPlan already carries its own Hash/Eq/fingerprint + contract test (phase 7 landed early).

OffsetMap carries LeafMeta; read/write_field dispatch on it (ADR-012 §2b, plan phase 5)
Prerequisite (review #005 M2): Hash added to Endian/VariableEncoding derives (additive; fieldless Eq enums), and to ByteRange. - New public types LeafMeta { kind, encoding, endian } (Copy + Eq + Hash) and OffsetEntry { range, meta } (start()/end() accessors), re-exported from lib.rs. Deferred decision 2 resolved: struct — get(path) -> Option<&OffsetEntry>, iter() -> (&str, &OffsetEntry). Storage: Vec<(String, OffsetEntry)>. - LeafMeta computed at compute time with effective endian threaded through the aligned walk (container default -> field override, propagated into nested-struct probes and array elements via the referring field, matching the aligned materializer). - engine read_field/write_field dispatch on the entry's LeafMeta: the per-access BastDoc re-parse + lookup_leaf_field walk + LeafFieldInfo are gone — the last two review #004 M1 sites. - Parity note: lookup_leaf_field computed nested-struct defaults from the nested struct's own endian annotation; the map now agrees with the aligned materializer and packed ReadPlan (referring-field propagation). The old divergence (nested struct declaring endian under a field that also declares one) is closed; no test pinned it. - Behavior change: read_field on a map-absent path (whole-struct field) errors Offset ("field not found") instead of Access ("composite types"); the composite-path test accepted either. - materialize_aligned's four offset_map.get call sites updated to .range.start. alktty/alkcall untouched (bench never uses OffsetMap::get; alkcall has no dependency yet). Verification: 465 tests pass (offset_map tests updated to the OffsetEntry shape with per-kind LeafMeta expectations; engine test for the old lookup walk rewritten to assert map entries carry the LeafMeta); clippy -D warnings clean; cargo doc zero warnings; wasm32 release build green. |

LayoutBuilder caches the owned BastDoc (ADR-012 §2a, plan phase 4)
The builder stores doc: BastDoc + endian (the doc_value: Value + root_name: String cache is gone); new parses the typed tree once and build walks &self.doc — the per-build BastDoc::new re-parse (layout_builder.rs M1) is retired. - build's root-is-struct re-check replaces its unreachable!() with a clean Schema error (AGENTS.md §3 never-panic; invariant unchanged — new already rejects non-struct roots). - Boxing fallout: the builder now holds the full owned tree, so Layout::Packed boxes it (Box<LayoutBuilder>) to keep the engine's Layout enum variant sizes balanced (clippy large_enum_variant). layout_builder() still returns Option<&LayoutBuilder> via auto-deref; public API unchanged.

Make BastDoc owned: drop Bast* lifetimes (ADR-012 §2a, plan phase 3)
Every Bast* type drops <'a>: &'a str -> String, &'a Value -> Value (deferred decision 1: plain String/Value — the tree is built once; Arc<str> name-sharing needs a bench justification that doesn't exist). BastDoc::new(&Value, &str) still takes references in and clones into owned storage; the doc gains Clone. resolve_ref/resolve_typeref/ resolve_typeref_as_def return owned types. - Engine ownership flip: AlkTypeEngine holds the owned BastDoc (replacing bast_doc: Value + root_name: String; root_name() delegates to the doc), killing its three per-call BastDoc::new re-parses (aligned validate_bytes, read_field, write_field — the review #004 M1 pattern removed by construction; phase 5 retires the lookup_leaf_field walk itself). New public accessor root_name() (additive). Engine Send + Sync with the owned doc, asserted in the existing thread-share test. - Bonus cleanup: materialize_typeref_packed's dead _field param dropped (phase 2 left it dangling). Under ownership, keeping it would force a deep Value clone per array element / record value / union variant via dummy_field_for. The param, dummy_field_for, and ty_source are gone; no behavior change (the arg was already ignored). BastField::synthetic keeps an owned-signature #[allow(dead_code)] definition (no remaining callers today). - Consumers adapted: OffsetMap::compute(&BastDoc), materialize_aligned(&BastDoc, ...) (no lifetime), BuildCtx/ ComputeCtx hold &'d BastDoc, tunion/discriminator name borrows, lib.rs module doc. LayoutBuilder's doc_value re-parse cache is unchanged pending phase 4.

Wire packed read path through ReadPlan (ADR-011 steps 2-4, plan phase 2)
SequentialReader now walks Arc<ReadPlan> instead of re-parsing the BAST typed tree per field (the 400x read-path gap, review #004 H1); materialize_packed walks the same plan, unifying the two packed read-side consumers on one compiled form. - SequentialReader::new(Arc<ReadPlan>) -> Self, infallible: the fallible BastDoc parse moved to ReadPlan::compile (phase 1). The reader holds the plan Arc + cursor state only; schema() returns the Arc<Value> retained on the plan (review #005 H2 — no self-referential struct); new plan() accessor exposes the shared plan. - ReadPlan carries schema: Arc<Value> (set at compile; sub-plans hold a Null placeholder — only the root plan is handed out). - materialize_packed(&ReadPlan, &[u8]): plan-walking packed materializer. The aligned path keeps walking BastDoc with the retained dummy_field_for/ty_source/materialize_typeref_packed helpers (phase 5 Scope Boundary: aligned structure walk is the permanent 0.3.0 design). - Engine: Layout::Packed stores Arc<ReadPlan> alongside the builder; sequential_reader() is an Arc::clone (was a full-document Value clone); packed validate_bytes calls materialize_packed(&self.plan). - Stride (deferred decision 4): FieldValue::Array now reports the true stride for fixed-size struct/nested-array elements (0.2.0 returned 0); doc comment documents the behavioral change; no existing test asserted the 0, so none needed changing. - Two parity subtleties found and preserved: (a) materialize_plan_composite unwraps the plan's anonymous single-field wrapper for primitive array elements/record values — without it, materialized records nest each leaf under a synthetic object (caught by the record parity test); (b) field-disc unions keep 0.2.0's materialized key order (__discriminator first), observable under preserve_order. Both are now covered by plan-phase tests or construction. Bench (alktty wire_vs_bast, 1024 chunks/stream): packed read 2.27 us/chunk (review #004) -> 98 ns/chunk p64 / 100 ns/chunk p4k (~23x; the 400x gap closes to ~17x vs hand-rolled 5.6 ns/chunk). Residual gap is the per-field String allocation mandated by the unchanged (String, FieldValue) read_next signature (2 allocs/chunk) plus data_access bounds checks. sequential_reader() construction: 15.7 ns (was a whole-document clone). Verification: 465 tests pass unchanged (the existing reader/ materialize/engine suites drive the rewrite through the public API — only constructor call sites moved to ReadPlan::compile); clippy -D warnings clean; cargo doc zero warnings; wasm32 release build green. |

Implement ReadPlan type + compile (ADR-011 step 1, plan phase 1)
Pure addition: the packed read-side compiled form (src/read_plan.rs) and lib.rs wiring (module + re-exports of ReadPlan, FieldPlan, CompositePlan, ReadKind, DiscriminatorPlan). No existing engine code touched — phases 2-5 wire the plan into the reader/materializer/engine. - Refined union shape (ADR-011 as refined by review #005): CompositePlan::Union { disc, shared, variants } with shared: Option<Box<ReadPlan>> for field-disc unions and variants: Vec<(String, CompositePlan)> — no VariantPlan/VariantKind, nested-union variants work by ordinary CompositePlan recursion (restores the 0.2.0 capability the POC rejected). - by_name is BTreeMap (ADR-012 §1 Hash-derive prerequisite). - True array strides (deferred decision 4): fixed struct/nested-array elements compute their real stride via fixed_composite_size; variable-length elements stay 0. 0.2.0 returned 0 for fixed struct arrays; that behavioral change rides the 0.3.0 bump (phase 2 will surface it through SequentialReader). - Endianness: effective endian baked at every node. Parity lock: the plan propagates the referring field's effective endian into nested structs/unions — what the 0.2.0 packed reader/materializer actually do — and ignores nested containers' own endian annotations (the POC baked s.endian() there; latent divergence, never exercised by its equivalence tests). Nested-annotation tests lock this in. - Untrusted input: compile carries its own depth cap (128) + definition-level cycle set (mirrors ValidationPlan::compile), so standalone compile is safe on adversarial docs: cyclic refs, deep chains, dangling refs, non-struct roots, and non-struct/union variants all surface as AlkTypeError::Schema, never a panic. Overflow-safe stride arithmetic (checked_mul). Verification: 388 tests pass (355 existing + 33 new: every BastType arm coverage, field-disc shared/nested-union compile shape, stride computation, endian parity, cycle/depth/malformed rejection, Send + Sync static-bound assertion); clippy -D warnings clean; cargo doc zero warnings; wasm32-unknown-unknown release build green.

Implement ValidationPlan (ADR-012 §3, plan phase 7)
The compiled value-domain validation form: replaces the interpretive BastDoc walk in validate_bytes with a compile-once-walk-many constraint tree built at engine-compile time. This was the design session + implementation ADR-012 §3 delegated; the shape decisions are recorded in new ADR-012 §3a. - New src/validation_plan.rs: ValidationPlan + ValidNode/ValidField/ ValidVariant (Debug+Clone+PartialEq+Eq+Hash+Send+Sync), compile(&BastDoc) with eager $ref resolution, and a per-buffer walk with deferred error-path rendering (zero happy-path allocation, byte-identical error messages vs the 0.2.0 walker). fingerprint() via DefaultHasher, same as the phase-6 pattern. - Compile-time graph safety: definition-level cycle set + depth cap (128) reject cyclic $ref graphs with AlkTypeError::Schema. The interpretive walker resolved refs lazily with no guard (stack- overflow hazard); diamond (shared) refs still compile. - bast_validation.rs: interpretive walker retired (deleted); validate_value survives as a one-shot wrapper (compile + validate) for callers holding a doc without an engine. - engine: Arc<ValidationPlan> built at compile in BOTH modes; the plan compile runs before the layout build and doubles as the engine's cyclic-ref gate (LayoutBuilder/OffsetMap struct recursion has no cycle guard; a cyclic doc previously overflowed there). validate_bytes walks the plan; new accessor validation_plan(). validate_bytes signature unchanged. - lib.rs: pub mod validation_plan + re-exports (ValidationPlan, ValidNode, ValidField, ValidVariant). Verification: cargo test --release (355 pass, incl. parity suite, fingerprint contract, cycle/depth rejection, Send+Sync + thread-share assertions); clippy --all-targets -D warnings clean; cargo doc zero warnings; wasm32-unknown-unknown release build green.

Resolve review #005: refine 0.3.0 plan + ADR-011/012
Resolve all 11 findings from the 0.3.0 plan review (#005) in one docs-only pass. No source changes; the crate still builds/tests at v0.2.0. The one substantive decision change is M3 (per user direction: ship ValidationPlan in 0.3.0, no more hedging); the rest are spec corrections or pre-implementation refinements to types that do not yet exist on main. - H1: refine ADR-011 CompositePlan::Union to carry shared: Option<Box<ReadPlan>> (field-disc shared fields) and variants: Vec<(String, CompositePlan)> (drop VariantPlan/ VariantKind). Plan phase 1 implements the refined shape. - H2: plan phase 2 specifies ReadPlan stores schema: Arc<Value> (not &Value), avoiding the self-referential struct ADR-011 rejects. Verified serde_json::Value: Hash + Eq holds with preserve_order, so phase 6 derives are not blocked. - M1: nested-union support falls out of the H1 shape refinement (a variant can be CompositePlan::Union) — option (a) from the review, no behavioral drop vs 0.2.0, no Semver regression row. - M2: plan phase 5 adds an explicit first sub-step to derive Hash on Endian and VariableEncoding in src/schema.rs (additive, semver-safe prerequisite the original plan omitted). - M3: reverse the ValidationPlan deferral. ADR-012's "Deferring ValidationPlan" becomes "ValidationPlan — in scope for 0.3.0"; new ADR-012 §3 commits the decision (compiled form, no per-buffer BastDoc walk, Hash + Eq + fingerprint()) and defers only the concrete shape to a follow-on design session + the plan's new phase 7. Plan gains phase 7 (ValidationPlan); old phase 7 (bump) renumbered to phase 8. ADR-011's Out-of-scope and Scope Boundaries bullets updated to point at ADR-012 §3. The deferral black hole this review's methodology flagged is closed: the work is committed with a concrete reactivation trigger, not hedged into an unplanned future. - L1: plan phase 2 corrects the dummy_field_for/ty_source removal claim — only packed-side call sites go away; the helpers stay for the aligned materialize_leaf_at path. - L2: plan phase 2 states the packed-vs-aligned materialize_typeref_packed split (packed gets a new plan-walking function; the existing function stays for aligned). - L3: plan phase 5 adds a Scope Boundary note — aligned materialize's BastDoc structure walk is the permanent 0.3.0 design; an AlignedPlan is out of scope, tracked as an OQ. - N1: fix "back-comat" -> "back-compat" typo. - N2: plan phase 1 verification adds the read_plan_is_send_sync static-bound assertion test ADR-011 requires. - N3: Semver Contract table notes the Result drop on SequentialReader::new (Result<Self, AlkTypeError> -> Self) alongside the argument-type change. Also: ADR-012 title -> "Plan Fingerprinting, ValidationPlan, and Closing the Deferred M1 Sites in 0.3.0"; §3 (Fingerprinting OffsetMap) renumbered to §4; README ADR table updated; review #005 gets a Resolution section recording how each finding was closed.

ReadPlan and OffsetMap. BTreeMap for ReadPlan.by_name (HashMap
blocks Hash derive). Fingerprint contract: equal hashes => identical
reads over identical bytes. Enables cross-run plan caching, alkcall
hub/spoke schema handshake, schema-version diagnostics.
- Closing the deferred M1 sites via owned BastDoc (lifetime removal,
scoped to LayoutBuilder/bast_validation/materialize_aligned/
OffsetMap::compute) + extending OffsetMap with LeafMeta
{kind, encoding, endian} for the aligned read_field/write_field paths.
Reframes the 'WritePlan' candidate from ADR-011's Future capabilities
section: the packed write-side compiled form is PackedLayout; the
aligned R/W compiled form is OffsetMap; the M1 fixes are 'cache the
parse' and 'extend the compiled form with leaf metadata', not 'add a
third compiled form.' Serves minimal-public-API-changes better than
a literal WritePlan type. ValidationPlan deferred (different shape,
not a hot loop).
The plan (docs/plans/030-compiled-forms.md) is the execution entry
point: seven phases ordered by dependency, each phase a session
boundary. Phase 1-2: ReadPlan (ADR-011). Phase 3: owned BastDoc.
Phase 4: LayoutBuilder M1 fix. Phase 5: OffsetMap LeafMeta. Phase 6:
fingerprinting. Phase 7: version bump + docs + verification. Includes
a semver contract table, deferred decisions, cross-phase invariants,
and the verification block.
ADR-011's Future capabilities section updated to point at ADR-012 for
the items moving into 0.3.0 and record the WritePlan reframe. README
ADR table gets ADR-012 as Proposed.
Verification: docs-only change; cargo test --release, cargo clippy

Accept ADR-011: compiled read plan for packed mode
Tighten framing per pre-acceptance review (no decision changes): - Be precise about M1 coverage: closes the packed-side site (engine.rs:284 validate_bytes); the aligned-side M1 sites (engine.rs:334,467, layout_builder.rs:190) are a deliberate reversible bet, not a non-issue. - Replace the 'two type walkers is symmetric with OffsetMap/ PackedLayout' spin with an honest 'parallel typed tree, permanent maintenance tax, justified by ~20-50x composite-dispatch win on SFTP-shaped union-with-$ref-variants packets.' - Move the 'determinism enables fingerprinting/cache/handshake' future work out of the positives list into a dedicated 'Future capabilities' section — it is a forward reference, not a current win. - Clarify bast_doc: Value is retained unconditionally (unused in packed mode, still needed in aligned mode); add a Send+Sync test note for Arc<ReadPlan> shared from the Send+Sync engine. - Tighten the 'no format! allocations' claim to 'no resolve_typeref, no BastDef::parse, no JSON node access on the happy path' (error- path format! remains, and is not the cost being removed). - Add a 'POC coverage' section recording that the readplan-poc branch walked every BastType arm and confirmed ReadPlan covers all cases, including the union Byte/Field split and the array variable-stride (element_stride = 0) case. Status flipped Proposed -> Accepted. README ADR table updated.

Propose ADR-011: compiled read plan for packed mode
Review #004 measured the packed read path at ~400x slower per chunk than a hand-rolled codec, root-caused to SequentialReader re-parsing BastDoc::new on every field read (the 're-parse on demand' framing from ADR-007). The write path is competitive because it has a compiled form (PackedLayout); the read path is the only mode/side pair without one. ADR-011 proposes ReadPlan — the packed read-side compiled form, symmetric to OffsetMap (aligned R/W) and PackedLayout (packed W). Packed positions are data-dependent (variable-length fields shift subsequent fields), so the compiled form is necessarily a read program (a pre-resolved tree of read instructions), not a flat lookup table like OffsetMap. ReadPlan::compile walks BastDoc once at engine construction, resolves all $ref\s eagerly, computes effective endianness at every node, and inlines union variants; the read loop then indexes into a Vec, matches on ReadKind, and calls data_access with a precomputed Endian — no BastDoc, no resolve_typeref, no JSON node access at read time. Scope: SequentialReader and materialize_packed consume the plan (one walker, not two); bast_validation, LayoutBuilder, and aligned one-shot paths stay on BastDoc (different concern, not hot loops). Includes a 7-step Recommended Order matching review #004's structure. Breaking public-API change (0.2.0 -> 0.3.0): SequentialReader::new and materialize_packed take ReadPlan; BastDoc and the Bast* types are unchanged (smaller breakage than review #004's Option A). Cross-links: ADR-007's 'Cost' section gets a Note pointing at review #004 and ADR-011, marking the 're-parse on demand' framing as the root cause slated for retirement (the factory decision itself is retained); the actual Cost/doc-comment rewrite happens in the implementation commit per ADR-011's recommended order. README ADR table updated. Verification: docs-only change, no source touched. Closes review #004 H1, M1 (packed side), L1, L2 (on implementation). |

Add review #004: read-path performance review
Traces the ~400x read-path gap (alktty wire_vs_bast bench) to
SequentialReader::read_field_at re-parsing BastDoc::new on every field
read, with the self-referential lifetime constraint as the root cause.
Findings:
- H1: per-field BastDoc::new re-parse in sequential_reader.rs:262
- M1: same re-parse in four one-shot paths (LayoutBuilder::build,
validate_bytes, engine read_field/write_field)
- L1: dead _field_schema param + Value clones in SequentialReader
- L2: ADR-007 Cost section + engine doc comment understate the re-parse
- N1: carry-forward of review #003 N2 (no new action)
Lays out fix options: Option A (owned typed tree, recommended, closes
H1+M1, breaking), Option B (read-plan precompute, fallback, H1 only,
non-breaking), Option C (borrow-from-engine, rejected, contradicts
ADR-007).
Verification: docs-only review; alktype source unchanged.

Left as historically accurate (describe the v0.1.0 pre-pivot state): ADR-003/004/006 Context mentions of AlkType:Timestamp, ADR-005 'engine now has 19', and the '19 jsonschema::Keyword factories' references in the What-is-removed sections of ADR-BAST and ADR-VAL-SPLIT.

Remove the Timestamp kind
The Timestamp kind was a residual from an early research reference. It was byte-identical to String everywhere (length-prefixed UTF-8) and its only distinguishing behavior was a hand-rolled non-strict RFC 3339 check that the docs admitted was incomplete (Feb 31 passes, seconds range unchecked, no leap seconds). JSON-level timestamp validation is jsonschema's job (format: date-time on the validate_json path), not alktype's. Removes the AlkTypeKind::Timestamp variant, its to_bast_str/from_bast_str mapping, the builder's Schema::timestamp() constructor, the validate_timestamp/is_rfc3339_timestamp validator arms, and the materializer/reader/engine timestamp arms. Updates the meta-schema primitive enum (14 -> 13), the spec docs (bast-format.md, schema-layer.md, builder.md, validation.md, overview.md, data-access.md, README.md), and the kind-count references (19 -> 18).

Resolve review #003 nits N1, N3, N4
- N1: number_from_f64 now returns AlkTypeError::Access for non-finite floats instead of silently materializing Value::Null. A NaN/Inf in the buffer surfaces as a clear access error rather than a misleading 'expected a number' validation error. - N3: drop the dead Value::String arm from check_bytes; the materializer only ever emits bytes as an array of u8. Update the validation-model docs to match. - N4: fix stale ADR references in doc comments (ADR-096 -> ADR-002, ADR-097 -> ADR-003, ADR-098 -> ADR-004, ADR-101 -> ADR-007). N2 (BastType::alk_kind returning Struct for ) left as documented; every current caller resolves the ref first, so forcing Option through the call sites is churn without benefit.

Resolves review #003 findings M1, M2, L1, and L2. - offset-indirect (L1 + M2 arm): rework read_*_indirect to same-buffer absolute offsets (safetensors-style, per the metatensor model) and add write_*_indirect. Wire the encoding dispatch into engine.read_field/ write_field and the aligned materializer. Previously the encoding was laid out but never read back. - field-level endian override (M1): thread field.effective_endian through sequential_reader, engine.read_field/write_field, and materialize_struct_aligned. Previously a per-field endian override was silently ignored, misreading multi-byte values. - aligned-mode materialization (M2): materialize fixed-size arrays via their vals[i] offset-map entries and maxLength reservations as zero-padded fixed-size slices (trailing NULs trimmed). Previously both read garbage or errored. - dead endian param (L2): drop the ignored endian argument from materialize_packed/materialize_aligned; endianness is read from the root struct.

Rewrite README for BAST pivot
The README still described the v0.1.0 custom-keyword JSON Schema format (`AlkType:*` kinds, `compile(&mut schema, mode)`, single jsonschema validator). Rewrite it for the BAST-era shipped API: - What-it-is table: two validation specs (bytes via BAST-native, JSON via consumer-provided JSON Schema) instead of one. - Usage example: `Definitions::new().build_doc(ChunkHeader, ...)` + `AlkTypeEngine::compile(&doc, ChunkHeader, LayoutMode::Packed, None)`; added a json!-literal variant showing the BAST document shape. - The 19 kinds table: lowercase BAST `kind` strings instead of `AlkType:*` keywords; note the enum index bounds fix. - Two layout modes: updated `compile` signature. - Variable-length handling: BAST field-level `encoding` annotation. - Union discriminators: `kind: union`, lazy variant $ref resolution, D-BAST-005 fields requirement. - Endianness: struct-level (was 'top-level schema'). - Validation: two validators (ADR-VAL-SPLIT), BAST-native for bytes, standard jsonschema for JSON; uniform AlkTypeError::Validation payload (D-BAST-009); enum bounds fix noted. - New 'BAST document shape' section: $defs required, root_name parameter, $ref restricted to #/$defs/<name>, BAST_META_SCHEMA re-export. - Untrusted input: BAST document (was 'schema'); BAST parser preserves the no-panic invariant. - Documentation index: updated for the new/rewritten docs and the ADR-BAST / ADR-VAL-SPLIT additions. Verified both code examples compile and pass against the shipped API (via a throwaway integration test, since removed). |

Sync architecture docs and ADRs to BAST pivot (steps 9-10)
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).

Remove v0.1.0 custom-keyword machinery (step 8)
The BAST parser (step 3) and BAST-native validator (step 5) replaced the v0.1.0 custom-keyword accessor layer; step 7 moved the builder to BAST output. This step removes the now-dead code: Removed from src/schema.rs: - get_alktype_kind / get_alktype_kind_enum / get_alktype_kind_loose / get_alktype_kind_loose_enum (replaced by the BAST parser's kind dispatch) - normalize_refs / inline_union_variant_refs + helpers (BAST refs are always #/$defs/<name>; resolution is a single hash lookup, variant refs resolve lazily) - parse_encoding / parse_align / parse_max_length / parse_endian (bast.rs has its own BAST-property-form copies) - parse_discriminator + DiscriminatorKind (replaced by bast::BastDiscriminator; builder has its own Discriminator enum) - resolve_ref / resolve_ref_or_inline (replaced by BastDoc::lookup_def / resolve_typeref) - FromStr impl, as_str, Endian::from_schema, ALKTYPE_PREFIX, BYTE_DISCRIMINATOR_TYPES, and the associated unit tests Kept: AlkTypeKind enum + methods (type_size, natural_alignment, is_fixed_size, needs_endian, is_composite, is_variable_length, to_bast_str, from_bast_str), Display (now backed by to_bast_str), Endian, VariableEncoding, U32_SIZE, DISCRIMINATOR_PATH. src/lib.rs: dropped the 13 schema::* helper re-exports and DiscriminatorKind from the public surface; kept Endian, AlkTypeKind, VariableEncoding. Doc/comment updates: bast.rs, builder.rs, engine.rs, error.rs — removed references to the deleted functions and the AlkType:* keyword form.

Builder API produces BAST JSON (step 7)
- Schema internals: flat Map<String, Value> → Repr enum distinguishing
BAST primitives (bare TypeRef strings), BAST composites (struct/
union/enum/array/record objects), $ref, standard JSON Schema
objects, and raw adopted values. Annotations (endian/align/encoding/
maxLength) stored on the Schema and placed correctly by build()
(struct-level) or field() (field-level).
- Primitive constructors (uint32, string, bytes, etc.) now produce
bare BAST kind strings ("uint32") instead of {"AlkType:Uint32":true}.
- struct_().field(...) produces {"kind":"struct","fields":[{name,kind,...annos}]}
with an ordered fields array (BAST design principle #4 — no reliance
on preserve_order for field order).
- union_() emits {"kind":"union","discriminator":{...},"mapping":{...}}
with BAST kind strings in the discriminator ("uint8" not
"AlkType:Uint8"). Field-name discriminator unions emit the fields
array; byte-offset unions omit it.
- enum_of() produces {"kind":"enum","values":[...]}.
- array_of(element).count(n) produces {"kind":"array","element":...,"count":n}.
.count() is an additive method (D-BAST-004 requires count; the
array_of signature is unchanged per the semver contract).
- record_of(values) produces {"kind":"record","values":...}.
- object()/string_()/etc. unchanged — standard JSON Schema output.
- encoding() now stores the value on the Schema; field() extracts it
as a field-level property. No more keyword-object duality.
- max_length() on standard types emits the standard keyword; on BAST
types it is extracted by field() as a field-level constraint.
- Definitions::build_doc(root_name, root) — new additive method
producing a complete BAST document with the root type inside $defs
(where BAST requires it). The old build()/merge_into() remain for
backward compatibility.
- All builder tests updated to expect BAST output shapes. New tests:
field annotations, field-name union with fields, array with count,
ref element, encoding emission, Definitions::build_doc round-trip
through compile(), SFTP-style union compile, array/record compile.
- Module doc comments updated (builder.rs, lib.rs).

validate_json against consumer-provided JSON Schema (step 6)
- AlkTypeEngine::compile gains a 4th param json_schema: Option<&Value>. When Some, a standard jsonschema::Validator is built from the consumer-provided JSON Schema and stored for the JSON-validation path. When None, validate_json returns AlkTypeError::Schema and is_valid_json returns false (D-BAST-007). - validate_json / is_valid_json signatures unchanged (per semver contract). Behavior: they now validate against the consumer JSON Schema, not a custom-keyword validator built from the alktype schema. The BAST document is not involved in this path. - build_validator repurposed (deferred decision #2): same signature, now builds a standard jsonschema::Validator with no custom keywords. Behavioral break, not a type break. Re-export kept. - Removed the 19 jsonschema::Keyword implementations and the 4 define_*_validator! macros (dead on the bytes path since step 5, now dead on the JSON path too). The is_rfc3339_timestamp helper lives on in bast_validation.rs (already copied there in step 5). - All compile call sites updated to pass None for json_schema (the layout/read/write/validate_bytes tests don't need JSON validation). - New tests: validate_json accepts/rejects against consumer JSON Schema, returns Schema error when no JSON Schema supplied, is_valid_json false when no schema, independence from BAST doc, malformed JSON Schema build error, nested object JSON Schema.

Add BAST-native validator for validate_bytes (step 5)
Replace the jsonschema custom-keyword validator on the bytes path with a recursive walker over the BAST typed tree. The materializer already guarantees structural correctness; the validator enforces only the value-domain constraints expressed in the BAST document. - New `src/bast_validation.rs`: `validate_value` dispatches on `BastType`, resolving `$ref`s lazily via `BastDoc::resolve_typeref`. Constraint arms: integer ranges (Int8..Uint64), float finiteness, string/bytes `maxLength` (from `BastField::max_length`), RFC 3339 timestamp shape, enum index bounds, union variant dispatch (recurses into the variant, recovering OQ-008 per-variant constraints), struct field presence, array count, record values. - `engine::validate_bytes` now calls `bast_validation::validate_value` instead of `self.validator.validate`. The `validator` field is still built and used by `validate_json`/`is_valid_json` (step 6 reworks those). - Enum index bounds check (`idx < values.len()`) fixes the v0.1.0 dead constraint: the built-in `enum` keyword checked string membership, but the materializer emits a numeric index that never matched. - Errors constructed via `jsonschema::ValidationError::custom` so `AlkTypeError::Validation` keeps its payload type uniform with the `validate_json` path (D-BAST-009). - `lib.rs`: add `pub mod bast_validation;` (engine-internal, not re-exported in the `pub use` block) and update the module doc.

Wire compile() to BAST document + root name (step 4)
Step 4 of the BAST pivot: the layout engines, materializer, tunion
dispatch, and engine now consume the BAST typed tree (BastDoc/
BastStruct/BastField/BastType/...) instead of walking raw JSON with
get_alktype_kind*.
Breaking changes (per the pivot plan's semver contract):
- AlkTypeEngine::compile signature:
compile(schema: &mut Value, mode)
-> compile(bast_doc: &Value, root_name: &str, mode)
Drops &mut (BAST needs no in-place normalize_refs); adds required
root_name (D-BAST-001); input is a BAST document, not a custom-keyword
JSON Schema.
- OffsetMap::compute, LayoutBuilder::new, SequentialReader::new now take
a BAST document (&Value) + root_name (or &BastDoc) instead of a
v0.1.0 schema.
- tunion::read_byte_discriminator / read_field_discriminator /
resolve_variant / discriminator_size now take &BastUnion instead of
&Value.
- materialize::materialize_packed / materialize_aligned now take
&BastDoc instead of &Value.
Key design points:
- The engine stores a clone of the BAST Value + root_name so
sequential_reader() and read_field() can re-parse the typed tree on
demand without lifetime entanglement with the caller's Value.
- resolution is a single hash lookup via BastDoc::resolve_typeref;
no normalize_refs, no inline_union_variant_refs.
- bast.rs gains BastField::synthetic() (pub(crate)) for constructing
synthetic fields wrapping TypeRefs (array elements, record values,
union variants — these aren't fields and carry no field annotations).
- The v0.1.0 schema.rs helpers and validation.rs custom-keyword
validators remain defined (step 8 removes them). build_validator still
runs on the BAST doc — with no AlkType:* keywords present, the custom
factories don't trigger and jsonschema performs structural validation
only. The validate_bytes value-constraint enforcement (maxLength, enum
bounds) is step 5's concern (the BAST-native validator).
Tests:
- All engine, layout, materialize, tunion, and integration tests
converted to BAST format (kind/fields vocabulary, /
composition). Expected validation outcomes for the layout path are
identical; the maxLength/enum-bounds validate_bytes tests are step 5's
regression target.
- builder.rs::builder_chunk_header_compiles_in_packed_mode uses a
hand-written BAST doc (the builder still emits v0.1.0 format; step 7
converts it).
Verification:
- cargo test --release: 425 pass (348 lib + 77 integration)
- cargo clippy --all-targets -- -D warnings: clean
- cargo build --target wasm32-unknown-unknown --release: clean
- cargo doc --no-deps: clean

Add BAST document parser (typed tree, step 3)
- New src/bast.rs: typed surface over a BAST document — BastDoc, BastDef, BastDefKind, BastStruct, BastField, BastUnion, BastDiscriminator, BastEnum, BastType, BastRef, BastArray, BastRecord. Borrows from the source Value (no clone of the tree). - $ref resolution is a single hash lookup against $defs (#/$defs/<name> only); union variant refs resolved lazily via BastDoc::resolve_typeref / resolve_ref — replaces normalize_refs + inline_union_variant_refs (those stay for now; step 8 removes them). - Untrusted-input safe: every walk returns AlkTypeError::Schema on a malformed document, never panic/unwrap (AGENTS.md §3). Overflow-safe usize parsing via try_from (AGENTS.md §4). - D-BAST-005 enforced: fields array only valid with field-name discriminators; required for them. - Additive only: new pub mod bast + re-exports in lib.rs. No existing re-exports removed (those go in step 8). 47 new tests. Verification: - cargo test --release: 465 pass (379 lib + 86 integration) - cargo clippy --all-targets -- -D warnings: clean - cargo doc --no-deps: clean - cargo build --target wasm32-unknown-unknown --release: clean |

Embed BAST v1 meta-schema as BAST_META_SCHEMA
Step 2 of the BAST pivot. Adds the normative BAST meta-schema (Draft 2020-12 JSON Schema) as a public serde_json::Value, embedded at compile time and available for validating BAST document well-formedness. Copied verbatim from docs/architecture/bast-format.md §The Meta-Schema. - New src/bast_meta.rs: BAST_META_SCHEMA static, built lazily via LazyLock (the json! macro allocates, so it can't be a const; parsed once, reused as &'static Value thereafter). - src/lib.rs: pub mod bast_meta + re-export BAST_META_SCHEMA. Additive public surface. The meta-schema validates structure (correct $defs shape, known kind strings, required properties, no additional properties, $ref restricted to #/$defs/<name>). Value-domain constraints (maxLength, enum index bounds) are enforced by the BAST-native validator (step 5), not this meta-schema. Verification: - cargo test --release: 418 tests pass (332 lib + 86 integration); 16 new unit tests exercise the meta-schema against valid and invalid BAST documents (missing $defs, unknown kind, additional properties, byte-discriminator union, enum, array+count, record, $ref, malformed ref, empty enum). - cargo clippy --all-targets -- -D warnings: clean. - cargo build --target wasm32-unknown-unknown --release: clean (LazyLock + serde_json::json! macro are wasm-safe). |

Add AlkTypeKind::to_bast_str/from_bast_str for BAST kind strings
Step 1 of the BAST pivot. Adds the lowercase-string mapping
("uint32" <-> AlkTypeKind::Uint32) that the BAST parser and
validator dispatch on (D-BAST-002).
- to_bast_str(self) -> &'static str: returns the lowercase BAST
string for all 19 variants (14 primitives + struct/union/array/
record/enum). Boolean -> "bool", distinct from the PascalCase
variant name.
- from_bast_str(s) -> Result<AlkTypeKind, AlkTypeError>: inverse of
to_bast_str; returns AlkTypeError::Schema for unknown strings.
These are additive inherent methods on the already-re-exported enum.
The existing FromStr impl (parsing the v0.1.0 "AlkType:Uint32"
keyword form) is unchanged and removed in step 8. The two surfaces
are deliberately distinct: from_bast_str rejects "AlkType:Uint32"
and FromStr rejects "uint32".
Verification:
- cargo test --release: 402 tests pass (316 lib + 86 integration);
6 new unit tests cover both directions, round-trip, and the
from_bast_str/from_str distinctness.
- cargo clippy --all-targets -- -D warnings: clean.

Decompose BAST pivot doc into normative spec + implementation plan
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). |

Add semver and ADR impact mapping for the BAST pivot
Scope-creep guardrail for the public API during implementation. Maps every item re-exported from src/lib.rs to a class (breaking / additive / unchanged) with the specific change, and every ADR (001-010) to an action (supersede / amend / unchanged) with the reason. Net breaking: compile (signature), validate_json/is_valid_json (contract), Schema::build/Definitions::build (output format), build_validator (signature or removal), and the ~13 schema::* helper re-exports. Net additive: BAST parser, BAST-native validator, AlkTypeKind::from_str/to_str. Net unchanged: the entire layout + data-access + materialize + tunion layer, AlkTypeError (D-BAST-009), the Discriminator builder, AlkTypeKind variants. Flags three small decisions deferred to their implementation steps (validate_json JSON Schema source, build_validator fate, schema::* re-export retention) so they don't become drive-by semver changes. This is a living guide — it may shift slightly during implementation, but capturing the contract now prevents public-surface drift. Doc-only. |

Resolve OQ-BAST-001: keep Validation(ValidationError<'static>) (D-BAST-009)
Converts the open question into a closed decision. Rationale: consumer ergonomics on the combined validate_json + validate_bytes path — one uniform payload type means one match arm downstream. Option 2 (Validation(String)) would force validate_json to flatten its structured errors to a String, losing information on the richer path to accommodate the less rich one. The no_std/minimal-build angle that option 2 was meant to enable is moot: validate_json requires jsonschema regardless, so a bytes-only no_std build already has to give up validate_json as a separate larger decision; dropping the type from one error variant doesn't unlock it. Updates Phase 1 step 5 to reference D-BAST-009 for the error construction pattern, and rewrites POC Result observation 4 from 'deferred decision' to 'decided — see D-BAST-009'. No semver-relevant change to the Validation variant. Doc-only. |

Refine BAST pivot: validation model, POC scope, resolve open questions
- Rewrite Validator Split around BAST-native validator for validate_bytes (walks BAST, checks value-domain constraints, no external JSON Schema needed); validate_json uses standard jsonschema::Validator from consumer-provided JSON Schema - Add targeted POC: BAST-native validator replacing 19 custom keyword validators on the bytes path, verified via existing test suite - Fix meta-schema: require count on arrays (variable-element arrays deferred per OQ-001), add optional fields array to UnionDef for field-name discriminators - Remove lying no-count array example, replace with deferred note - Document dead enum constraint (materialized index never matches string-membered enum); BAST-native validator fixes it via index bounds check - Resolve all 7 OQs + 3 spec gaps as D-BAST-001 through D-BAST-008 - Update Migration Path, Risks table, Engine internals to reflect BAST-native validator - Clarify 'no pocs needed' was an overcorrection: layout swap needs no POC, but the validation model does Verification: docs-only change, no code affected |

Clean up BAST pivot: drop POCs, remove recursion, add spec gaps
- Remove the four proposed POCs: they were implementation smoke tests, not de-risking probes. The pivot is a backend swap on a proven layout engine; byte-identity is already proven and the layout code is unchanged, so there is nothing empirical left to de-risk. - Remove the recursive TreeNode example and the recursion mention in design principle 2: recursion is not a binary-layout concern and the engine has no cycle detection. - Add a Spec Gaps section: validate_bytes semantics after keyword validator removal (UnionValidator variant dispatch regression), arrays of variable-length elements (engine rejects them), and field-name discriminator unions (meta-schema cannot express them). - Reframe the engine change as an accessor-layer refactor: the walkers' (kind, field list, annotations) reads change; everything beneath them carries over unchanged. |

Fix BAST pivot: jsonschema remains a direct dependency
Correct the validator split section to clarify that jsonschema is not removed — it remains the JSON Schema validator for both paths (BAST meta-schema validation and standard JSON payload validation). Only the custom keyword registration path is removed. Also fix the build_validator and validate_json entries in the engine changes table to reflect that they are repurposed, not removed. |

Pre-publish docs sweep: README, AGENTS.md, licenses, inline doc fixes
- Add README.md reflecting the v0.1.0 state: 19 AlkType kinds, two layout modes, builder + AlkTypeEngine usage example (verified to compile and run), validation entry points, crate independence, untrusted-schemas guarantee, docs pointers. Mirrors the alkvault README structure. - Add AGENTS.md with alktype-specific git workflow, project conventions (no comments, AlkTypeError, untrusted schemas, overflow safety, no async, no feature flags, wasm-clean, preserve_order load-bearing, no unsafe), verification commands, and ADR/OQ index. Blocks auto-commit on semver-relevant public API changes per the crates.io 0.1.0 contract. - Add LICENSE-MIT and LICENSE-APACHE (dual MIT/Apache-2.0, matching alkvault and the Cargo.toml license field). - Cargo.toml: add readme, keywords, categories, rust-version = "1.85". - Fix broken intra-doc link in builder.rs: DiscriminatorKind -> crate::schema::DiscriminatorKind (cargo doc now warning-free). - N1 (review #002): document is_rfc3339_timestamp as non-strict in the function doc comment. Lists the specific gaps (day-of-month per month, seconds range, leap seconds) and points consumers needing strict validation to chrono/time. - N2 (review #002): document the FieldValue::Bytes-for-Record API asymmetry in the FieldValue enum doc and on read_record_value. - .opencode/agents/implementation-specialist.md: point to AGENTS.md for full convention details (matches the alkvault pattern). - review #002: mark N1/N2 resolved; all 7 findings now closed.

Fix L2: replace unreachable! with Err for untrusted-schema safety
The immediate downstream consumer (alkcall) accepts schemas from
arbitrary internet peers in its hub/spoke topology. A panic is the
wrong failure mode for a malicious or unsupported schema - an Err
the caller can handle is correct.
Three sites converted:
- offset_map.rs: _ => Err(Offset { unsupported AlkType kind for
aligned offset computation })
- layout_builder.rs: _ => Err(Offset { unsupported AlkType kind
for packed layout computation })
- materialize.rs: _ => Err(Schema { internal: union discriminator
type N is not a supported byte discriminator })
The materialize.rs site uses Schema (not Access) because a wrong
disc_type is a schema-authoring bug (parse_discriminator should have
caught it), not a buffer-access error. The sibling sites in
sequential_reader.rs and tunion.rs already returned Err(Schema) -
only materialize.rs was the holdout.
Note: the k if k.is_fixed_size() guard in offset_map and
layout_builder means the compiler cannot enforce exhaustiveness at
compile time. Converting _ from unreachable! to Err is the runtime
mitigation. A future refactor could list all fixed-size kinds
explicitly to restore compile-time checking. Deferred to a separate
cleanup pass.
Verified: no unreachable! remains in production code (the one
remaining hit at offset_map.rs:688 is inside a #[test] fn).
