glm-5.3-flash 6bce301c55 docs(tasks): decompose wave 2 — mem + local engines, facade, in-process GC, first suite columns
Nine tasks against the wave-1 contract surface as reviewed (no
amendments from the gate):

- engine-mem / engine-local (parallel, dependency-free): the two
  engines; local owns the stage-hygiene exact-count tests and the
  Drop-cancellation story the wave-1 review recorded
- store-construction: the Store type, constructor modes, size-threshold
  dispatch; binds the conformance factory's Store associated type
- store-read-paths ∥ gc-protocol: read ops with the ADR-012 §6.1
  fall-through rule; the ADR-005 in-process protocol (pins, liveness,
  delete windows, abort-as-data, GcRefuse with the full protection set)
- store-put-paths: the two put paths behind one signature, ADR-003's
  three numbered rules, pin-before-publish, Batch, kv-only rejection
- suite-column-mem → suite-column-local: the reference column, then the
  dual-tier dispatch-coverage shape mirroring it
- review-wave-2: the gate (facade/dispatch/GC vs ADR-003/005/012)

Verification: dependency graph validated (all ids resolve, no cycles,
topological order clean); docs-only change.

glm-5.3-flash c1d9494c11 docs(tasks): the wave-1 review gate — the one-way-door audit green
Every gate check read against the cited ADR text: the key encoding
holds byte-exact against ADR-002 (tags, lengths, rejects, sort order,
preamble abstraction, live git-CLI interop, lowercase oid policy
recorded); the trait + I/O seams + engine-state seam match ADR-003/
010 and ADR-012 §5's reduced table; the error model's five variants
and single-enum altitude reading match store-api.md/ADR-012 §6.5; the
feature graph matches ADR-013 §4; all named design points audited
consistent; the suite convention and backlog are traceable; family
conventions clean. One inline fix: publish keyword `bao` -> `git`
(excluded technology named in metadata). Wave 2 decomposition
unblocked, no amendments.

glm-5.3-flash 327b952e4d feat(tests): the conformance suite's home — conventions, invariant backlog, harness skeleton (wave 1)
- tests/conformance/README.md: the convention doc — row naming (property-
  stated names, engine dimension is the column), the Contract stamp:
  format (the alkstore ADR-017 §4.2 convention adapted), the one-
  normative-owner-per-property rule, the factory contract (fresh
  isolated instance per open, idempotent teardown, safe over an
  abandoned instance), the SKIP posture (SQL-attached columns skip
  cleanly server-less; acceptance requires green against the server),
  the invariant backlog (the seven store-api.md §Invariants registered
  as the rows-to-grow table with pinning citations), and the mem-first
  column plan (mem is the contract-reference engine, ADR-011 §2)
- harness skeleton, compile-able with zero rows: StoreFactory (fresh
  + isolated + idempotent-teardown contract; the Store associated type
  is wave 2's binding point for the facade type), stamp.rs (the
  marker + convention anchor), backlog.rs (in-code registry with a
  traceability gate asserting INV-1..7 mirror §Invariants in order)
- no engine-specific code; no dependencies added

glm-5.3-flash 0547c17876 feat(backend): the Backend trait, I/O seams, engine-state seam shape, and facade value types (ADR-003/010)
The wave-1 contract surface: everything engine-blind that waves 2-6
implement against. No engine bodies, no facade behavior logic.

- src/backend.rs: the pub(crate) Backend trait — seven methods +
  put_staged, opaque byte keys/values, size metadata-only, list
  complete-and-well-formed, virgin-store reads as no-ops (ADR-003,
  ADR-008); the ReadCursor/StagingCursor I/O seams with the read_range
  slice-digest convention (ADR-006) at one seam; unit tests against
  both body-family doubles, a test-double engine, and the stage-hygiene
  invariant's two forms (discard; commit failure self-discards).
- src/gc.rs: the engine-state companion seam as EngineWindowState /
  EngineFleetState — ADR-012 §5's applicability table expressed
  structurally (no dead machinery); JointTx ownership rule pinned in
  the signature (store holds the tx; engine contributes mechanics).
- src/facade.rs: EntryMeta, Pin, Batch, SweepReport, GcAbortCause
  (x3, #[non_exhaustive]), PinState with lifecycle contracts
  (ADR-005, ADR-012 §1); re-exported from lib.rs.
- Design points pinned for the wave-1 review gate in
  tasks/core-trait-and-types.md: pub(crate) trait visibility,
  associated-type put-form shapes, AFIT + associated types (no dyn).

Verification: cargo test (26 lib + 3 git-interop), cargo test
--all-features, clippy --all-targets -D warnings (default and
--all-features), cargo fmt --check, cargo doc --no-deps — all green.

glm-5.3-flash fef05b4ec5 feat(keys): the content-address layer — canonical hash derivation and key encoding (ADR-002)
Wave 1 task core-hashing-keys: the crate's declared one-way door,
implemented byte-exact to ADR-002.

- src/hashing.rs: Algorithm (exactly GitBlobSha256 canonical /
  GitBlobSha1 tolerated; BLAKE3 absent), Digest (known-length
  derivation H("blob <len>\0" + content) as primary constructor;
  from_git_oid_hex interop constructor, lowercase-only acceptance),
  and the hashing::registry constants (0x01/0x02, 0x00 reserved; new
  algorithm = new ADR)
- src/keys.rs: typed Key wrapper; as_bytes/from_bytes are the only
  backend-boundary conversions; 1 algorithm byte + digest bytes
  (33/21 total); rejects-never-guesses validation -> Error::KeyInvalid
- tests/git_interop.rs: the load-bearing test — byte-exact derivation
  against the `git hash-object` CLI, both algorithms, small and
  75-KiB content; external-oid round-trip into pool keys; both oid
  formats coexisting in one flat pool
- named design point (oid hex policy): lowercase-only acceptance,
  recorded in the task Notes and on from_git_oid_hex

Verified: cargo test (15 passed), cargo clippy --all-targets -- -D

glm-5.3-flash fc5ab57d18 feat(errors): the one-enum error family with altitude discipline
- src/error.rs: thiserror Error enum with the five ADR-012 \u00a76.5
  variants (Missing, Verification, Io(String), GcRefuse, KeyInvalid);
  doc comments carry store-api.md \u00a7Error model's semantics and the
  one-enum/two-altitude discipline (trait's effective members are
  Missing/Verification/Io/KeyInvalid; facade re-exposes with GcRefuse)
- no #[non_exhaustive] per the ADR-pinned variant set; Error derives
  Debug/PartialEq/Eq
- lib.rs re-exports Error
- unit tests: variant construction, the single-enum altitude shape,
  and the Missing-is-never-get/stat-absence doc contract (facade
  behavioral enforcement lands in wave 2)

glm-5.3-flash 24d1c68343 feat(crate): scaffold the ADR-013 §4 feature graph and module skeleton
- Declare the decided feature graph in the manifest: sqlite default-on
  (rusqlite 0.40 bundled), postgres (tokio-postgres 0.7 +
  deadpool-postgres 0.14), mem (dependency-free), pg-lo pulling the
  shared pg driver cluster only (no postgres implication, ADR-010 §1),
  ops (alkcall 0.8.1, default-off); local ungated
- Replace the placeholder crate body with the module skeleton: lib.rs
  re-export shape, ungated stubs (hashing, error, backend, facade,
  dispatch, gc, local), engine stubs behind #[cfg(feature)]
  (mem, pg_lo, postgres, sqlite, ops); stubs are doc-comment-only so
  wave-1 tasks own the module bodies

Verification: cargo test green (default); cargo check --all-features
resolves the full graph; cargo check --no-default-features --features
pg-lo resolves with rusqlite provably absent (tree-inverted match) —
the ADR-010 §1 no-implication rule; clippy --all-targets -D warnings
and cargo fmt --check clean.

glm-5.3-flash 8a2df4fa57 docs(plans): implementation plan — wave-based decomposition; wave 1 decomposed into tasks/
- docs/plans/implementation.md: the meta plan (alkstore pattern) — nine
  waves, dependency logic, decided points, review gates. Scope authority:
  v0.1.0 ships the full surface (all five engines, fleet GC, ops).
- Wave 1 decomposed: scaffold-crate-features, core-error-model,
  core-hashing-keys, core-trait-and-types, suite-scaffold,
  review-wave-1 (the one-way-door gate).
- Waves 2-9 shaped in the plan; each decomposes after the prior wave's
  review gate.

  'feature graph re-pinned: ...', 'REQ-5 added: ...') broke Gitea's
  frontmatter parser in docs/architecture/README.md,
  backends-and-dispatch.md, and requirements.md

glm-5.3-flash bee86b0dbd docs(architecture): ADR-013 — family composition, reactive boundary, sweep lease; OQ-11 resolved
- No sibling (alkstore) dependency in-core; reactivity is
  deployment-layer composition above the facade — cadence stays
  embedder-owned (ADR-005), with alkstore the named substrate for it;
  in-crate notify/scheduler/queues/invalidation hooks are non-goals.
- Fleet sweeper lock pinned as 'named exclusive sweep lease'
  semantics; shipped provider unchanged (pg advisory clause);
  provider swaps are ADR-007-shaped substitution doors.
- Composition contract for downstream ADRs: co-tenancy of CAS/GC
  state + reactive machinery + consumer/liveness tables on one fleet
  host; no-cross-store-atomicity ruled; compensation rests on
  idempotent re-puts, windowed deletes, sweeps-as-report-data.
- OQ-11 resolved (the register's one live circular hedge): engine
  features pull their own driver clusters — sqlite becomes feature
  'sqlite' (default-on, carries rusqlite); 'kv'/'large' tier features
  retired; 'local' ungated; pg-pure builds are supported,
  non-default. Deciding fact already in-tree (REQ-2/ADR-009).
- requirements.md: UC-4/REQ-5 records the composition facts
  (operator record 2026-10-11, corroborated by alkstore's
  consumer-inventory).
- Publish guard stated pre-code: facade ships before publish;
  semver-is-contract from first publish (alkstore ADR-017 discipline).
- Amended accepted ADRs' feature wording (ADR-010 §1, ADR-011 §3/§4,
  ADR-003) with supersession notes; README/overview/open-questions/
  backends/store-api/gc aligned; parked index now empty.

Verification: docs-only round (no Rust surface touched); full-tree
single-value check on the feature graph and sweep-lease wording.

glm-5.3-flash 7b9d904b8a docs(architecture): ADR-012 — pre-decomposition consistency rulings; tree verified single-valued
Full-tree review before task decomposition found five composition
defects (mechanisms specced correctly in isolation, composition
unruled) and a set of caller-facing gaps. ADR-012 rules each:

- Sweeps are never errors: aborts are GcAbortCause report data in
  Ok(SweepReport) (ProtectFailed / SweeperLock / NoLivenessSources);
  GcAborted retired from the error enum; direct-delete refusal is
  the GcRefuse error covering the full protection set
- Pin token gains its wire shape: blobs/put response {token, digest};
  blobs/have's token-renewal form (one digest + token); token
  validity domain = the minting serving node, process-lifetime
  mapping
- Fleet mode is an explicit constructor declaration (fleet: true),
  never inferred from engine choice
- All fleet GC state hosts on the fleet's kv engine (postgres) — one
  arbitration domain; large=pg-lo fleet nodes required onto the same
  pg instance (composite predicate's new clause); large=local fleet
  puts pin-row-first, publish-second
- Engine-state seam reduced: sqlite pin/sweep-lock bodies dropped
  (dead machinery); non-SQL engines stage delete-window candidates
  in-process; one-window-host rule per instance
- Facade clarifications: fall-through for all key-addressed ops,
  kv-only put-time rejection, mem+local dual-tier valid, error-model
  member/return-shape ruling (trait/facade family split), has ->
  bool, PinState variants, fleet liveness-table registration form,
  window executor = the next sweep

Alignment edits across all specs and ADR-005/008/009/010/011
(bracketed corrections per the established pattern); OQ-11 (pg-only-kv
feature graph) added to the parked index for auditability.

Verification: two independent review passes; all findings resolved;
verdict READY for task decomposition.

glm-5.3-flash abf8c5ae9c docs(architecture): ADR-010/011 — I/O seams, GC-state home, vocabulary; pre-decomposition consistency round
ADR-010 (new): the Backend trait's I/O seams pinned before any code —
'get' returns a crate-internal read cursor (kv engines materialize;
'local' pread loop; pg-lo lo_get windows), 'put' has two named forms
(whole-value kv / staged-put large); GC state is store-core-owned via
a crate-internal contract-tested engine-state seam on the SQL-backed
engines (backends never learn liveness — ADR-005 verbatim); the store
core holds the joint entry+pin transaction (corrects ADR-009 §2's
ownership statement); kv-tier fleet-validity rule added (mirror of
ADR-008 §3); ops pin-token TTL race resolved (the token IS the pin;
renewal rides have/re-put; pause-past-TTL falls to delete-then-recover);
feature graph pinned (pg-lo does not imply postgres).

ADR-011 (new): vocabulary pinned — tier (contract, exactly two) vs
engine (concrete impl, exactly five); store instance / node / fleet
split (fleet = pool-sharing, not node count — fixes requirements.md's
self-contradiction with REQ-2); mem demoted from 'backend'/'testing
tier' to the kv tier's third engine (contract-reference engine);
fs tier renamed 'large' including the feature name (last free moment
before code exists); constructor modes pinned (dual-tier default,
kv-only, mem-only) plus the composite fleet-validity predicate.

Consistency round across all specs and ADR-003/004/007/008/009: stale
pg-lo passages resolved per ADR-009's supersession; ADR-008 owner
'node id' → store-instance id; threshold wording corrected (conservative
edge, not midpoint, of the 128-256 KiB crossover zone); SweepReport
shape specced; mem classification unified; 008/009 ADR files renamed to
match the tier rename; README deferral-policy recap aligned (third
category = decided-but-sequenced work, not a parking kind); POC crate
list completed.

Verification: two independent architecture review rounds (the first
found 4 criticals — unpinned trait I/O shapes, missing fleet-state
seam, node/fleet self-contradiction, pin-token/TTL conflict — all
resolved; final round: zero criticals); all markdown links resolve;
ADR tables complete (11 ADRs).

glm-5.3-flash 9bbe6f3ad9 docs(architecture): ADR-009 — pg-lo admitted as the fs tier's second engine on POC #7
- ADR-009 (new): postgres Large Objects ship as the fs tier's second
  engine (feature pg-lo, default-off), admitted on POC #7's passed
  gate (contract 10/10, durable put ~= fs at >=1 MiB, lo_get window
  gets, transactional LO lifecycle = zero crash orphans). Engine
  shape: companion table (lo_entries) is the contract authority; put =
  one tx (lo_create + lowrite + row + pin); get = descriptorless
  lo_get windows (lo_*64 discipline); named operator deltas (catalog
  space never returned / autovacuum inherited / sweep for the legacy
  bypass class only) and named performance deltas (cached-get 20-50x
  behind page-cache fs single-stream, ~700 MB/s aggregate at 16
  readers = the fleet serving picture).
- Ripple: backends-and-dispatch (pg-lo shipped; fleet locality
  contract gains the whole-fleet-pg-lo option), overview (layer map,
  feature table + pg-lo row, OQ -> shipped pointer), requirements
  (engine def + REQ-2 note updated), README (current-state + ADR
  table), store-api (invariant 1/6 engine lists), ADR-008 Status
  amendment (pg-lo posture superseded by ADR-009), open-questions
  (audit trail completed: decided -> sequenced -> completed).

Verification: docs-only; all cross-references resolve (ADR/REQ/POC);
register, findings, spec, and both engine-ADR status lines agree.

glm-5.3-flash cee97defba docs(research): POC #7 — postgres Large Objects as the fs-tier pg-lo engine, passed
The ADR-008 pg-lo admission POC ran in a standalone crate
(/workspace/alkblobs-pglo-poc): PgLoBackend over the ADR-003/008 trait
contract (including size), 10/10 exact-count sweep-outcome contract
tests, clippy/fmt clean; dockerized postgres:16-alpine on :15432,
POC #5 driver stack (tokio-postgres + deadpool) via SQL lo_* functions,
no new dependency.

Gate verdict: passed, with named deltas.

- Performance: durable put 60-65 MB/s at >=1 MiB, within 1.5x of — and
  below 1 MiB beating — durable local fs on this fsync-slow disk;
  cached gets 70-180 MB/s single-stream, ~0.7 GB/s aggregate over 16
  readers (20-50x behind page-cache fs — the honest named delta)
- Contract: companion table is the list()/size()/CAS authority (never
  the catalogs); stage-then-commit; GC-participating lo_unlink delete
- Handles: the tx-scoped descriptor is real but pool-compatible via
  descriptorless lo_get(oid, off, len) windows — window gets keep
  handle-acquire p99 at 1-6 ms under readers <= pool; held descriptor
  is the fallback posture
- Vacuum: pg_largeobject pages churn-reused, never returned; tracked
  by autovacuum; rel-size monitoring named as an ops requirement
- Crash/orphan: LO creation is transactional — kill/terminate
  mid-write-tx leaves zero orphan pages; the only orphan class is a
  committed LO bypassing the companion table (planted, reaped by the
  ~7 ms/oid sweep; committed content survives byte-exact)
- Harness lessons: lo_lseek is int4 — the 64 variants are the
  >2 GiB discipline; shared-table parallel tests are unsound (per-test
  CREATE DATABASE isolation)

Docs: new poc-pglo-findings.md; poc-pglo-spec.md status passed;
register OQ-BL-06 #7 marked passed; ADR-008 pg-lo bullet updated
(duplicate bullet removed) + backends-and-dispatch/open-questions
cross-references.

Verification: cargo test --release (10 passed), clippy -D warnings,

glm-5.3-flash 281c37876e docs(architecture): ADR-008 — trait size probe, fleet GC, fs-tier engines; requirements anchor
- requirements.md (new): the three use cases pinned as REQ-1..4 with
  the node/pool/fleet/engine vocabulary defined once — ends per-session
  re-derivation of consumer facts. REQ-2 (replicator fleet over one
  shared pg pool, incl. large-blob serving) is recorded as a planning
  fact predating all POCs, on the operator's authority.
- ADR-008: Backend trait gains size(key) length probe (before any
  backend ships data — ADR-002 one-way-door discipline); fleet GC
  mechanism (DB-backed pin rows committed atomically with entries,
  TTL+renewal semantics, liveness = embedder-owned table, protect
  callback is single-node-only, advisory-locked single sweeper,
  staged re-arbitrated delete window on both engines); fs tier becomes
  engine-selectable (local default; pg-lo named candidate) with the
  fleet locality contract (shared media or re-routing; mixed tiers are
  a documented deployment invariant, not a constructor-provable one).
- poc-pglo-spec.md (new): POC #7 spec — pg Large Objects as the fs
  tier's pg-lo engine; instruments, decision gate, registered in
  phase-0.md OQ-BL-06.
- ADR-003/005 status amendments point to ADR-008's extensions; specs
  ripple (backends/store-api/gc/ops/overview/README).
- open-questions.md: deferral-policy header gains the decisions-vs-
  sequenced-work distinction; pg-lo's why-not-parked audit trail
  recorded.
- research fixes: postgres POC renumbered #4->#5 to the canonical
  register (phase-0 OQ-BL-06), redb cross-refs fixed, thinking-
  artifact sentence in B1 replaced with the honest reading.

Verification: docs-only change; reference-integrity sweep across the
tree (ADR/REQ/POC refs resolve); architecture-reviewer pass on the
delta — original 3 criticals addressed, its follow-up (fleet liveness
form, pin TTL, staged-delete semantics, enforceability, shared-media
caveats) fixed in this commit.

glm-5.3-flash 395d58cf3f docs(architecture): ADR-007 — two kv engines (sqlite + postgres) behind one trait
Dissolve OQ-10's circular "standing offer" framing and record the
engine decision the POC evidence already supported:

- ADR-007 (new): kv tier ships sqlite (default) + postgres (feature
  `postgres`, default-off), constructor-selected per node; records the
  deployment economics (classical kv+fs+relational downstream stack
  collapses to one relational engine + fs), the pg impl contract
  (POC #5 B5 posture deltas), the CI sweep-safety gate under
  --all-features, redb ruled out (POC #6), and posture defaults as
  deferred cost in the ADR-006 pattern
- ADR-003: amended status (engine pin widened by ADR-007); kv entry
  notes the widened engine set
- ADR-004: reconciliation note — the "two backends" count is tiers,
  not engines
- backends-and-dispatch.md: tier≠engine distinction, pg engine
  section, co-tenancy note (same-file consumer writes share sqlite's
  single-writer ceiling), substitution-door precedent
- open-questions.md: OQ-10 resolved-by-ADR-007, with the
  why-this-is-not-Schrödinger's-code record (a deployment running
  alkblobs cannot pre-exist the pg engine — OQ-09 precedent); parked
  index narrowed to OQ-07/OQ-08
- overview.md: layer map + dependency posture reflect the `postgres`
  feature; README.md: ADR-007 in tables + corollary applications
- phase-0.md / pg+redb findings: promotion + supersession notes

Trigger framing survives only as deployment guidance (which engine a
node chooses — topology, not throughput), not as a gate on the crate's
own work.

Verified: cargo test, clippy --all-targets -D warnings, fmt --check.
Docs-only change (Phase 1 architecture); no implementation yet.

glm-5.3-flash 1af9399900 docs(architecture): OQ-10 — postgres as the second shipped kv engine, a standing offer on a deployment trigger
Records the two-engine story the POC #5/#6 round established, in the
terms this crate's boundary uses (engine, not backend; trait contract
as the admission gate):

- OQ-10 (externally-owned standing offer): open the postgres-kv ADR
  when a multi-tenant replicator deployment materializes. Trigger is
  topology, not throughput — cross-machine write access to one pool
  (throughput pressure / sqlite's flatline is the early warning).
  Names the trigger-time work: PgKv impl + engine-posture deltas
  (synchronous_commit, pooling/prepared-statement discipline,
  autovacuum, ~40x storage overhead) + the sweep-safety proof
  (vacuum-stable list() cursor, exact-count sweep tests). Sequenced:
  sqlite stays Phase 1 mainline; evidence base is done and waiting.
- poc-postgres-kv-findings.md: engine deployment posture section —
  the three use cases (self-hosted git serving, p2p replicator nodes,
  agent-workspace pools) mapped onto the measured curves; per-node
  choice as the form of the fork; honker parity stack named for the
  pg side (LISTEN/NOTIFY + pgboss-rs, deployment layer).

No code changes; engine work parallelizes against the fixed contract.

glm-5.3-flash 5eea656295 docs(research): POCs #5/#6 — postgres and redb as the kv engine, both substitution-seam inputs
Post-convergence engine studies against the ADR-003 kv pin, using
POC #3's harness unchanged (sqlite/fs arms byte-identical) plus the
concurrency axis POC #3 never measured:

- #5 postgres (B1-B6): solo pg floor ~1 ms (fsync-dominated, strace-
  decomposed), ~40x storage overhead; decisive scale-out — pg PUTs ~12x
  at 12 conns / ~37k ops/s while sqlite flatlines at its ~1.2k WAL
  single-writer ceiling. Viable future ADR for the multi-client
  replicator shape; durability/ops posture change, not a drop-in.
- #6 redb (C1-C6): the "2-7x over sqlite" folklore inverted — sqlite
  ~430x over redb at crash-consistent puts (redb Immediate = 1
  fdatasync/commit, 8-30 ms on this disk; its None tier is not
  crash-consistent). Reads ~530k/s but irrelevant. Ruled out at a
  durability-tier mismatch: WAL-NORMAL's shipped tier is not
  expressible in redb 4.x's two-level API.
- Net: sqlite's pin now has four-way triangulated evidence (fs vs
  sqlite #3, pg #5, redb #6, lineage citation); batched commits proven
  as the universal lever across all three engines.

Code: /workspace/alkblobs-postgres-poc, /workspace/alkblobs-redb-poc
(standalone crates per the POC placement convention; 14 inherited
tests passing in each, clippy -D warnings + fmt clean).

glm-5.3-flash e403b22e26 docs(architecture): clarify Backend trait scope and kv/sqlite framing
The backends spec read as if the Backend trait were a general storage
abstraction and 'two backends, exactly' banned other storage in a
deployment — so a downstream wanting sqlite manifests appeared forced
into implementing a third backend, the exact weld ADR-004 forbids.

- backends-and-dispatch.md: state plainly that the trait is a CAS-tier
  contract (immutable digest-keyed entries, GC-shaped list/delete) and
  never a host for manifest/index storage; consumer storage is
  beside-the-pool. 'Two, exactly' counts trait impls shipped, not
  storage per deployment. kv: tier name vs pinned sqlite engine made
  explicit.
- ADR-004: add the explicit corollary under the consumer-seams point.

glm-5.3-flash b18521a0e6 docs(architecture): dissolve OQ-09's self-referential deferral
- OQ-09 resolved closed-by-default (deny-unlisted), decided on risk
  asymmetry in hand, not on a first deployment the crate itself must
  create; named reopen condition instead of a parked wait
- delete oq-09-ops-visibility-tracker.md (watch-task for an event the
  crate itself gates — never collapses)
- fix doc-lifecycle circularity: externally-owned OQs no longer block
  a spec's `reviewed` promotion
- gc-and-namespaces: "until a consumer names a requirement" reframed
  as re-entry via a new ADR, not a parked question
- README: state the corollary explicitly — facts this crate must
  create (its own first deployment/consumer) are never deciding inputs

Verified: full-text sweep for stale OQ-09 deferral/tracker references
comes up clean across docs/ and tasks/.

glm-5.3-flash 4b5009d85a docs(architecture): Phase 1 spec tree — 7 specs, ADRs 001-006, OQ tracker
- overview/hashing/store-api/backends/gc/ops specs + README index,
  all draft status with YAML frontmatter and cross-referenced ADR/OQ
- ADR-001: substrate posture (store layer alkcall-free = family
  conformance, not deviation) + ops placement decided (feature-gated
  module, no consumer-waited deferral)
- ADR-002: canonical git-blob-sha-256 + key encoding — the declared
  wire-format ADR (one-way door)
- ADR-003: backend contract, sqlite/fs/mem tiers, pure-function
  dispatch, no migration, unknown-length buffering semantics pinned
- ADR-004: exactly two production backends; manifest/path-tree layers
  are consumer-side (the corrected two-vs-three-backends framing)
- ADR-005: pooled CAS, three liveness sources, delete windows with
  pin-before-publish + delete-time arbitration (race closed), no
  ambient scheduling
- ADR-006: whole-blob verification; chunk-tree encodings excluded by
  scoping, not deferred on a paused consumer
- open-questions.md: OQ-BL-01..06 resolved with ADR cross-refs; OQ-07
  /08 externally-owned, OQ-09 deferred(scope) with SDD tracker task
- AGENTS.md: status updated to Phase 1, gix-odb path corrected

glm-5.3-flash 7d9ac8a6ec docs(research): correct layer vocabulary — alkcall has no transport code
- Verified against alkcall 0.8.1: no networking deps; Connection wraps
  a caller-provided established stream (ADR-012 dial/call decoupling)
- 'transport' was being used loosely for 'wire/ops protocol'; now
  reserved for endpoints/dialing/byte-moving, which is in neither
  crate. Ops/framing/ACL surface = wire/ops protocol (alkcall's layer)
- Vision sentence, scope line, OQ-BL-01 argument, and alkcall
  prior-art entry rewritten with the accurate layering; alkcall entry
  now states the transport-free fact explicitly
- iroh-blobs-eval.md: 'welded to their transport' -> 'welded to their
  protocol stack (endpoints/transport weld on above it)'

glm-5.3-flash b0b385d94e docs(research): settle OQ-BL-01 substrate — ops surface rides alkcall, with the argument recorded
- The 'alkcall usage undecided with the first wire consumer' posture
  was an inherited assumption, never a decision; it conflated iroh-
  blobs' actual weld (no Store trait, store inseparable from irpc —
  convention 7's rejection target) with having a protocol substrate
  under the ops layer at all
- Settled: ops surface is alkcall-shaped — validated JSON control ops
  (OperationSpec/JSON Schema, ADR-016 error schemas), binary data
  channels via the channel_open marker (ADR-047; Sub ADR-021 fetch,
  Pub/Sink ADR-046 put), ACL via AccessControl + ownership (ADR-011)
  under the ADR-017 privilege model; an in-band op/auth scheme would
  duplicate reviewed family machinery (convention 6 already mandates
  the seam)
- Store layer stays substrate-agnostic (principle 1 unchanged); alkcall
  enters only at the ops module/sibling boundary
- Remaining Phase 1 ADR scope reduced to placement: feature-gated ops
  module (lean) vs sibling crate
- Synced vision sentence, scope line, alkcall prior-art entry,
  OQ-BL-05 ACL line, recommended approach, decision table

glm-5.3-flash 1f905003d0 docs(research): Phase 0 convergence — settle OQs, add decision table + ADR backlog
- phase-0.md: fold chronological accretion into a settled posture;
  status -> converged; OQ-BL-01..06 restated as settled-base +
  named residuals; new Convergence section (recommended approach,
  decision table, Phase 1 ADR backlog); plan section marked complete
- iroh-blobs-eval.md: fix crossover numbers (64-128 -> 128-256 KiB,
  matching POC #3 finding A4) and B-finding -> finding-A4 reference
- poc-largeblob-findings.md: summary-table label fix (B-finding ->
  finding A4); align small-blob multiplier with measured 9-10x

glm-5.3-flash 6b278fb490 docs(research): POC #3 passed — large-blob streaming + sqlite-vs-fs benchmark
- POC #3 (register OQ-BL-06) executed and passed: streaming LFSObject-shaped
  put/get at the store layer; fanout seam (serve-while-persisting) validated
  as broadcast above the backends; fs range reads with the verification gap
  documented (preamble makes slice-vs-whole verification impossible —
  chunk-tree encoding sharpened to a transfer-layer conditional)
- sqlite-vs-fs micro-benchmark: first-party anchor for the small-blob
  belief (~9-10x sqlite at 1-16 KiB, crossover ~128-256 KiB, 128 KiB
  default lean); harness re-runnable on real media
- Stage-file hygiene tests caught a real leak (one temp file per failed
  put) — fixed; all failure paths converge on discard
- Pack tension resolved in shape from the gix-odb read: packs as large
  blobs served by range reads; object-level dedup lives in the loose tier
- iroh-blobs-eval.md written against the current checkout (e82cbdc /
  v0.103.0): actor/message-protocol pattern, fs backend layout,
  verification, do-not-inherit + keep lists
- alknet probe re-check demoted to historical cross-check only: alknet's
  code is not a design input (decomposed; substrate is alkcall); its
  small-blob perf claim was asserted-never-measured, superseded by A4
- phase-0 register complete: no open POCs; next step is convergence ->
  Phase 1

Verification: POC crate (standalone /workspace/alkblobs-largeblob-poc)
14 tests pass, clippy -D warnings clean, fmt clean; digests byte-exact
vs the real git hash-object CLI on both streaming put paths

glm-5.3-flash 493516424a docs(research): POC #1 passed — trait contract + digest + dispatch
POC code: /workspace/alkblobs-trait-poc (17 tests passing, clippy -D
warnings + fmt clean; digests validated byte-exact against the real
git hash-object CLI, both object formats)

Findings (poc-trait-dispatch-findings.md, 8):
- lean Backend trait (opaque byte keys, complete list(), put-path
  pinning) is sufficient; Key typed wrapper lives at the boundary
- redb traps: list() key-vs-value destructure (silent until GC
  catches it — malformed list is as deadly as incomplete), virgin-db
  TableDoesNotExist on first read, no in-memory db (temp file used)
- pinning: Pinned RAII guard + refcount map works; batch-scope pins
  and the sweep-vs-put race are named Phase 1 requirements (iroh
  DeleteSet = prior art)
- git-blob preamble abstraction validated; external-git oids address
  pool entries with zero indirection (the OQ-BL-03 resolution,
  implementation-confirmed)
- tagged key format ([algo byte][digest]) makes git-sha256 + git-sha1
  coexist; sort-stable for sweep diffs
- dual dispatch works as simply as hoped; routing deterministic
- namespace tables: protect callback MUST share live state (the
  snapshot-install bug proves the API lesson: register_liveness_source
  shape, not install_into)
- GC semantics verified: exact deletion counts, abort-callback,
  delete-then-recover byte-identical re-put

phase-0.md: POC #1 marked passed, #2 absorbed (validated), #4 covered
in miniature (concurrency half deferred to Phase 1 impl work);
OQ-BL-02 base settled; OQ-BL-03 implementation-validated; OQ-BL-05
mechanism settled with findings folded in; plan updated (POC #3 is
the last open POC)

glm-5.3-flash cde279b76d docs: hash simplification — canonical git-family hash resolves BLAKE3
- OQ-BL-03 RESOLVED: BLAKE3's presence traced to pure iroh-blobs
  inheritance; with that rejected the multi-hash framing dissolves.
  Three tiers: canonical git-blob-sha-256 (git oids + every other
  consumer share one address domain — cross-consumer dedup free),
  tolerated git-blob-sha-1 (protocol necessity, git's hardened-SHA-1
  threat model), conditional BLAKE3 (only if a bao-like chunk-tree
  encoding is ever adopted; confined to that encoding layer)
- Principle 2 rewritten (one canonical hash, git-family derivation);
  alkgit consumer entry updated (the 'hash conflict' was an artifact
  of the BLAKE3 inheritance); p2p section notes strengthened dedup
- OQ-BL-04: verification options no longer BLAKE3-mandatory; chunk-
  tree encoding note — verified wholes register under the canonical
  hash so chunked and whole-file paths dedup together
- POC register: #2 absorbed into #1 (postamble abstraction + SHA-1
  tolerance are #1's trait work); #3 gains the sqlite-vs-fs
  micro-benchmark pull-out
- AGENTS.md convention 5 aligned (canonical git-family derivation)

glm-5.3-flash 55450d6bf0 docs(research): consolidate GC/pooling round into phase-0
- iroh-blobs GC mechanics verified against current checkout:
  mark-and-sweep (named tags + TempTag RAII + ProtectCb with abort),
  format-aware mark traversal, DeleteSet write-safety, no namespaces
  (flat tags) — our namespace concept maps onto their machinery
- rudolfs prior art section: StorageKey(ns, oid) composite key +
  decorator storage stack; THE ANTI-PATTERN inverted (physically
  namespaced storage defeats cross-tenant dedup); list() is
  load-bearing; verify-as-decorator; streaming LFSObject + fanout
- OQ-BL-03: oid<->hash mapping DISSOLVED — git's oid derivation is
  itself a hash algorithm (domain-separated preamble); per-algorithm
  namespaces; mapping only reappears for transfer-vs-storage hashes
- OQ-BL-05 consolidated: physically flat/logically namespaced; tags
  are the root table; references stay above the crate; mark-and-sweep
  with protect-callback lean (a) + TempTag pinning; traversal
  ownership (a/b/c) is the Phase 1 ADR
- POC register updated: #1 adds list() completeness + pinning
  contract, #2 reframed as validating oid-dissolution, #4 as the GC
  worked example; 'what each POC decides' section added

glm-5.3-flash 5e0a594cfd docs(research): fold p2p-git/dedup discussion into phase-0
- Consumers: add agent workspaces (third consumer); add the p2p shape
  section (contract/gossip/replicator sketch) and pin what it implies
  here: pooled CAS per node, repos/workspaces as hash-reference sets
- Principles: add 6 (pooling is the point) and 7 (whole-file CAS
  default; CDC scoped to large-binary edits; fixed-size trees not
  inherited)
- OQ-BL-01: ops surface upgraded from speculative to likely (have/need
  + verified fetch), crate-boundary question remains
- OQ-BL-04: chunking scoped; new sub-question — chunking in store
  encoding vs manifest layer
- New OQ-BL-05: pooling/GC — namespace shape, lifetime strategies,
  the pack tension (constrains store surface)
- POC register: add #4 (pooled CAS + GC); note pack tension rides #3
- gix-odb: note alternates/object-pools as cross-repo dedup prior art

glm-5.3-flash 7f7f70b220 feat: initial repo setup (Phase 0 scaffolding)
- AGENTS.md: repo conventions adapted from alkcall/alksocks (store
  posture, multi-hash requirement, no-iroh-wire rule; no fuzz gate yet)
- Cargo.toml + src/lib.rs: bare lean lib skeleton (tokio async, thiserror)
- docs/research/phase-0.md: Phase 0 draft — vision, prior art (iroh-blobs
  store, gix-odb, alknet appfile probe, alkcall), OQ register, POC plan
- .gitignore, LICENSE-APACHE/MIT
- Re-pointed stale alknet/alkcall references in .opencode/agents/ and
  docs/sdd_process.md

Verification: cargo build/test, cargo clippy --all-targets -- -D
warnings, cargo fmt --check, cargo doc --no-deps — all pass
