- Line 345: Extend the “No stale authority references” verification to include
all non-KEEP disposition beads, specifically magic-context-9o6.1,
magic-context-9o6.2, and magic-context-a9p in addition to the existing REWRITE
buckets and KE children. Ensure each open bead’s body is checked for the listed
forbidden legacy tokens while preserving the existing exemptions for closed and
untouched beads.
- Around line 253-254: Update the U7 dependency-removal list to remove the
3q5.10 → 3q5.8 edge, since 3q5.10 is closed by U5 before U7 runs and its
outbound edge becomes inert; keep the list limited to edges from surviving open
beads.
- Line 16: Revise the plan’s Authority statement to distinguish architectural
planning from Beads storage authority: specify that all issue reads, writes, and
synchronization use bd and Dolt, while .beads/issues.jsonl remains a passive
export; state that the plan defines target bead content only until those
operations are implemented, and remove the implication that the plan overrides
Beads or permits direct JSONL edits/imports.
- Line 268: Update the U1 workflow to capture all four created child issue IDs,
then pass every ID to the bd status update with deferred status instead of
invoking bd update without IDs. Verify each deferred child individually with bd
show.
- Around line 251-252: Update the dependency commands and verification steps in
the plan to add K6 and K8 relation edges explicitly as relates-to rather than
depends-on, and verify both depends-on and relates-to edge types so required
non-blocking relationships cannot be omitted or misclassified.

| - **Objective:** Beads backlog describe exactly one memory architecture, the daemon-authoritative semantic kernel, so implementer pick up any open task without hitting contradictory requirements, dead references, or work scheduled against deleted machinery. This plan file is interim architecture authority (KTD5); `ARCHITECTURE.md` and `docs/migration-version-lanes.md` realign later with kernel task K9. | ||
| - **Means:** Rewrite, close, create, re-wire beads per Bead Disposition Table. Stand up new kernel epic (KTD3, KTD5). | ||
| - **Authority:** This plan supersedes missing `docs/plans/2026-08-16-001-refactor-retrieval-storage-overhaul-plan.md` as tie-breaker for epic `magic-context-3q5` and new kernel epic. Bead conflict with this plan: plan wins until bead rewritten. |

Separate planning authority from Beads storage authority.
The plan can define the intended architecture, but it must not replace the Beads source of truth. The repository contract says Dolt is authoritative and .beads/issues.jsonl is a passive export. The upstream Beads workflow has the same storage model. (github.com)
State that all reads, writes, and sync use bd and Dolt. State that the plan only defines target bead content until those operations land. This prevents direct JSONL edits or imports from creating tracker divergence.

Beads bd CLI relates-to typed relation command issue 3936 dependency add
💡 Result:
Issue 3936 in the Beads (bd) CLI relates to a bug in the bd list command's tree renderer, specifically regarding how it handles the relates-to dependency type [1][2]. The issue stems from the renderer incorrectly treating relates-to edges as hierarchical parent-child relationships rather than loose graph links [1][2]. This caused two primary problems: 1. Incorrect nesting: Issues linked via relates-to were being visually nested under one another in the bd list output [1][2]. 2. Silent data loss: In cases of bidirectional relates-to links (e.g., A ↔ B), the renderer would detect a cycle in the hierarchy and incorrectly skip rendering both involved issues entirely, even though they were still present in the underlying data [1][2]. This bug was triggered by using the bd dep add command to create dependencies with the --type=relates-to flag [1]. The issue was resolved by a commit on May 27, 2026, which modified the buildIssueTreeWithDeps function to explicitly filter out relates-to dependency types before building the tree structure in bd list [2]. This ensures that relates-to links are no longer treated as hierarchical edges, preventing the incorrect nesting and the silent dropping of issues [2].

Specify and verify the typed relation edges.
U7 lists only bd dep add <issue> <depends-on> and verifies only blocking depends-on edges. Use bd dep add --type=relates-to for the K6 and K8 relations, then verify both depends-on and relates-to edges. Otherwise, the checks can pass while a required relation is missing or blocking.

Remove the closed-source edge from the U7 removal list or document the exception.
The list includes magic-context-3q5.10 -> magic-context-3q5.8, but U5 closes magic-context-3q5.10 before U7 runs. The next bullet says outbound edges owned by closed beads become inert and need no removal. Keep removals limited to surviving open dependents, or move this removal before U5 and define the ordering.

Beads CLI bd update status issue ID syntax --status deferred
💡 Result:
To update the status of an issue to deferred in the Beads CLI, use the bd update command with the --status flag [1][2]. The correct syntax is: bd update --status deferred [2] If you omit the , the command will update the last touched issue [1][2]. You can also perform bulk updates by providing multiple issue IDs [2]: bd update --status deferred [2] Supported built-in statuses include: open, in_progress, blocked, deferred, closed, pinned, and hooked [2][3]. If you encounter an error, ensure the status is spelled correctly, as the CLI validates inputs against this list [2][3]. [1][2][3]

Extend stale-token verification to all rewritten open beads.
The check covers REWRITE buckets and KE children, but U4 also rewrites magic-context-9o6.1, magic-context-9o6.2, and magic-context-a9p. These beads can retain forbidden legacy tokens and still pass the gate, while the Definition of Done requires every open disposition-table bead to use kernel-era vocabulary.
Enumerate every non-KEEP disposition bead, or add these three IDs explicitly.

Deletion propagates to search documents, embeddings, derived support, admission status, and sets backfill barriers. |
There was a problem hiding this comment.
On a power loss after the SQLite commit, fsyncing the temporary file before rename does not guarantee that the renamed directory entry survives; the canonical row can therefore reference a missing artifact despite the stated durability invariant. Require an fsync of the destination directory after the atomic rename and before committing the canonical reference.

This ordering makes K8 depend on K7 even though K7 must prove R8's stale-search-to-prompt and search-deletion behavior, which requires the eligibility routes/thin client implemented by K8 and the search.sqlite projection that is itself blocked on K8. Following bd ready therefore cannot complete K7 and unlock the implementation under test; split the kernel-only proofs from the end-to-end proofs or make the latter depend on K8 and the projection.

Despite the plan declaring the c50 epic and all children untouched, this export rolls c50.8 back from its 2026-08-26 state to 2026-08-22, drops its cross-harness hardening notes, and removes the still-in_progress c50.8.2 and c50.8.3 records. That erases the tracked external release work from the committed backlog snapshot, so regenerate the export from a Beads database containing the newer parent and its children before landing.

Shared kernel provides: object registry (stable cross-type `object_id`, kind, domain, creation commit; no shared truth/status/confidence semantics), immutable proposition primitive (subject, predicate, value, value schema, normalized hash; no truth status), predicate schemas, entities and aliases, bounded scope algebra with typed anchors (git commits treated as DAG, never linear interval), evidence metadata, typed cross-object edges with asserted relations physically separate from inferred relations. | ||
| - R5. Canonical, staging, derived are hard classes. Staging (extraction runs, candidates, model scores, admission decisions) never reaches canonical retrieval or automatic prompt injection. Derived state (current projections, alignment, retrieval docs, FTS, embeddings) is rebuildable from canonical state. | ||
| - R6. Memory domain has exactly one schema shape, created at full shape. Identity detected via existing direct-format vocabulary (application id, format marker, pristine-or-exact open); any mismatch quarantines and rebuilds. No migration chain, no version fences beyond discard, no compat shims, no dual-read, no backfill. Wire-protocol and transform-domain version mechanics (mc-host `PROTOCOL_VERSION`, store.db transform tables, shm transport) out of scope for this rule. | ||
| - R7. v86 semantics carry forward re-expressed on kernel: maturity ladder (CANDIDATE→CORROBORATED→VERIFIED→APPROVED→ENFORCED), source-taint classes and promotion rules, visibility matrix, bitemporal validity, git-anchor applicability. v86 implementation (TS claims layer, claim mirror, authority convergence) deleted. |

R7 promises to carry forward bitemporal validity while closing the old 3q5.32 implementation, but none of K2, K5, or K6 owns the replacement fields or query semantics: K2's schema scope omits valid-from/valid-until and known-from/known-until data, K5 only owns scopes and anchors, and K6 only owns admission and visibility. K1–K10 can therefore satisfy their stated acceptance criteria and delete the claims layer without restoring bitemporal behavior, making historical and applicability queries incorrect; assign the schema, writers, reads, and tests explicitly to a kernel child.

The rewritten task declares dependencies on both magic-context-kh8.2 and magic-context-kh8.4, and its records require decision or observation links, but its dependency array contains only K2. Once K2 closes, bd ready can offer this task while K4's typed decision/observation stores are still unavailable; add the planned blocking edge to K4.

No string labels anywhere; every \"dimension\" is a\ncompile-time array index, so series count stays below 128 scalars and is independent of traffic, job\nids, request keys, or text.\n\n| Instrument | Kind | Unit | Dimension (fixed) | Site |\n|---|---|---|---|---|\n| `cpu_wait.query` | histogram | ms | none | mod.rs:499 select -\u003e grant arm |\n| `cpu_wait.batch` | histogram | ms | none | mod.rs:641 select -\u003e grant arm |\n| `cpu_hold.query` | histogram | ms | none | CPU permit grant -\u003e blocking-task completion; includes blocking-pool queue + native inference |\n| `cpu_hold.batch` | histogram | ms | none | grant (mod.rs:648) -\u003e after the `settle_inference` match (mod.rs:670-688); includes blocking-pool queue + native inference |\n| `inference.query` | histogram | ms | none | immediately around `backend.embed` inside the blocking closure |\n| `inference.batch` | histogram | ms | none | immediately around `backend.embed` inside the blocking closure |\n| `cpu_wait_outcome.query` | counter[4] | count | granted, timeout, waiter_gone, cancelled_or_closed | mod.rs:499-518 arms |\n| `cpu_wait_outcome.batch` | counter[3] | count | granted, cancelled, closed | mod.rs:641-649 arms |\n| `queue_full` | counter[6] | count | parse_reservation_unsatisfiable, parse_resident_exhausted, parse_coverage_short, query_admission, job_admission, result_page_resident | one helper, all six sites |\n| `poll_outcome` | counter[7] | count | restarted, key_mismatch, bad_cursor, failed, pending_queued, pending_running, page | mod.rs:729-733 |\n| depth gauges | computed on read | count / bytes | free_cpu_permits, free_query_permits, jobs_active, jobs_retained, queued_text_bytes, retained_result_bytes | `snapshot()` only |\n\n`query_admission_rejected` is `queue_full[query_admission]`; do not add a second counter for it.\n\n**Histogram semantics.** Fixed edges in ms: `[1, 2, 5, 10, 20, 50, 100, 200, 500, 1000, 2000, 5000]`\nplus one overflow bucket = 13 `AtomicU64`, each observation lands in exactly one bucket\n(`edge[i-1] \u003c= v \u003c edge[i]`), plus `count` and `sum_us` (microseconds, saturating) so the mean is\nexact and two snapshots merge additively. Edges at 50/100/200 are chosen deliberately: they straddle\nthe 50ms `retry_after_ms` quantum (`mod.rs:81`) and the client's 100ms `queue_full` backoff\n(`packages/plugin/src/features/magic-context/memory/embedding-synapse.ts:1453-1454`) that s64 must\nremove. **The host computes no percentiles** -- exact percentiles keep coming from the load\ngenerator's sorted vectors (`docs/perf/mc-host-baseline.md`, \"Percentiles computed over all requests\nof one run (exact, sorted vector)\"). Host buckets answer *where the time went*, not *how long*.\n\n**Cost bound to verify, not assume.** Per request: a bounded number of `Instant::now()` reads and\nrelaxed `fetch_add`; per poll: one fixed counter update. Memory is six fixed histograms plus fixed\noutcome counters, under 1 KiB, with zero per-request allocation and zero per-job metric state. The\nmodel-free overhead experiment decides whether these reads and shared atomics are acceptable; no\nnanosecond estimate is treated as evidence.\n\n**Fast path.** Start with the existing in-process snapshot pattern and fixed relaxed atomics; do not\nadd observer dispatch or dynamic labels. Treat its cost as a hypothesis until the model-free overhead\nrun. The lane-unavailable paths return before instruments are touched. If fresh evidence shows the\nclock reads or shared atomics are material, the minimum fallback is one optional snapshot pointer and\none predictable guard per site, not a new framework.\n\n## Required skills and execution order\n\n1. `/systems-design:metrics-audit` owns names, units, fixed dimensions, bucket boundaries, cardinality, mergeability, privacy, and consumer usefulness.\n2. `/quantitative-analysis:statistics-and-benchmarking-discipline` fixes which observations the instruments represent. Attempt and logical-request metrics, service and wait time, and terminal outcomes must not be conflated.\n3. `/performance:perf-pipeline` ensures instruments answer the queueing/concurrency decisions rather than adding generic telemetry, and coordinates the model-free overhead baseline.\n4. `/systems-design:bounded-design` verifies metric storage and recording work are fixed-capacity, non-blocking, allocation-free on request paths, and safe under overload.\n5. `/quantitative-analysis:benchmark-experiment-design` is required for the before/after overhead claim, including process-level units, A/A path validation, replication, and stopping.\n6. `/testing:test-strategy` chooses bucket-boundary, exact-attribution, concurrency, snapshot, and privacy tests. `/implementation:rust-implementation` applies the minimal in-crate snapshot pattern.\n\n## Implementation Guidance\n\n### Files to Modify\n| File | Change | Rationale |\n|---|---|---|\n| `crates/mc-host/src/synapse/mod.rs` | add private fixed metrics/snapshot/histogram state; field on `SynapseInner`; initialize in both constructors; record at the table sites; expose `metrics()`; extend `health()` | all recording sites live here |\n| `crates/mc-host/src/synapse/jobs.rs` | `pub fn depth(\u0026self) -\u003e JobDepth` after `key_is_retained:319`, reusing `lock_jobs` and `Job::is_completed:130` | table internals are private |\n| `crates/mc-host/examples/synapse_host.rs` | print one `serde_json` snapshot line to stderr on shutdown (and every `--stats-secs N` if passed) | only cross-process consumer; no wire op needed |\n| `crates/mc-host/tests/synapse_metrics.rs` (new) | snapshot contract tests | mirrors `tests/broca_supervisor.rs:80` |\n| `crates/mc-host/tests/synapse_protocol.rs:142` | extend the existing `queue_full` case with the counter assertion | reuse, don't duplicate the fixture |\n| `docs/perf/mc-host-baseline.md` | short \"Synapse instrument semantics\" subsection: names, units, bucket edges, what `cpu_hold` includes | the measurement contract doc s64/ioi cite |\n\n### Patterns to Follow\n- `SupervisorMetrics` + `Supervisor::metrics()` (`broca/supervisor.rs:203-291`) -- snapshot struct built from `available_permits()` + table sizes. Copy this shape.\n- `HealthReport.metrics` JSON keys with `_ms` suffixes and tests asserting them: `crates/mc-module/src/lib.rs:294-302` and `lib.rs:16679-16688`.\n- One funnel per policy: add `fn queue_full(inner, reason, message) -\u003e RequestOutcome` next to `app_error` (mod.rs:417) and route all six sites through it, so a future `queue_full` site cannot silently escape counting.\n\n### Blast Radius\n`SynapseInner` is private; `SynapseComponent::new`/`ready_with_engine` signatures do not change, so\n`examples/synapse_host.rs`, `tests/support/synapse.rs`, and every existing synapse test compile\nuntouched. `health()` gains a `metrics` payload on the `Ok` arm (previously `HealthReport::ok()`,\nmetrics `None`) -- `tests/synapse_bundle.rs:156` only asserts `status`, so it stays green. No wire\nchange: `protocol::decode_request`, `docs/mc-host-wire-protocol.md`, `tests/protocol_vectors.rs`,\nand the TS client are out of scope.\n\n## Testing Strategy\n1. Bucket unit test in `mod.rs` `#[cfg(test)]`: values at every edge and one overflow land in the\n documented bucket; `count == sum(buckets)`; `sum_us` matches the observations.\n2. `queue_full` attribution: the existing overload case (`tests/synapse_protocol.rs:142`) bumps\n `queue_full[query_admission]` exactly once and creates no job; a saturated job table bumps\n `queue_full[job_admission]` and `jobs_active == max_queued_jobs`.\n3. Wait/hold/service attribution: a gate-controlled engine via `ready_with_engine` blocks before and\n inside inference; snapshots distinguish `cpu_wait.query`, `cpu_hold.query`, and `inference.query`,\n with exactly one granted outcome. Repeat for batch. Assert bucket membership and counter identity,\n never wall-clock equality.\n4. Poll accounting: `pending_queued`, `page`, `restarted` each increment exactly once per\n `embed.result` call, including the multi-page path (no double counting per item).\n5. Contract test: snapshot JSON key set and units are stable, and the payload contains no job id,\n request key, content hash, or text (metrics-audit privacy rule).\n\n### Benchmark overhead gate\nRe-run the model-free tiny-engine arm from `magic-context-515` (see memory\n`embedding-machinery-baseline-21bd53d0`) before and after, 3 open-loop runs each, same host/commit\ncontract as `docs/perf/mc-host-baseline.md`. Gate: median throughput delta and `embed.query` p99\ndelta must be within the measured run-to-run spread, and the report must state that spread (n=3\nmedians cannot resolve \u003c1% honestly -- claim \"no detectable regression\", not \"0.4% faster\"). If a\nregression exceeds the spread, drop the clock reads from the poll path first, then revert.\n\n## Related Work\n| Task | Relationship |\n|---|---|\n| `magic-context-s64` | blocked by this: needs `cpu_wait.*` + `queue_full[*]` + `poll_outcome[*]` to prove the 100ms staircase is gone |\n| `magic-context-ioi` | blocked by this: needs `cpu_wait`/`cpu_hold` split and depth gauges to judge a concurrency topology |\n| `magic-context-18r` | consumer: `cpu_hold.batch` bounds the duplicate-preprocessing win |\n| `magic-context-09u` | consumer: client-side yield fix, verified against the same counters |\n| `magic-context-515` | closed origin of all four |\n| `magic-context-09q` | parent enrichment umbrella |\n\nWiring: `bd dep \u003cnew-id\u003e --blocks magic-context-s64` and `bd dep \u003cnew-id\u003e --blocks magic-context-ioi`.\n\n## Acceptance Criteria\n- [ ] All instrument groups in the table exist with the documented units and bucket edges, and\n `SynapseComponent::metrics()` returns them in one allocation-free snapshot (depth gauges\n computed on read).\n- [ ] Every `queue_full` return in `synapse/mod.rs` routes through the counting helper (grep shows no\n bare `app_error(\"queue_full\", ...)` left in the file).\n- [ ] Snapshot carries no unbounded or sensitive value: no job id, request key, content hash, text,\n or per-item state; series count is a compile-time constant.\n- [ ] `health()` exposes the snapshot as JSON and one test asserts its key/unit set.\n- [ ] Tests 1-5 above pass; `bun run test:rust` and `cargo clippy --workspace --all-targets -- -D warnings`\n and `cargo fmt --check` are clean.\n- [ ] Overhead gate reported in `docs/perf/mc-host-baseline.md` with n, spread, and verdict.\n\n## Stop Conditions (do not exceed)\nStop when s64 and ioi can split a tail into wait / hold / rejection / poll from one snapshot, and the\noverhead gate passes.

Today the query embedding can be held behind the\nwhole local SQLite/FTS scan because the pre-dispatch yield is one microtask, while\nboth real provider chains need more than one microtask hop to reach their\ntransport call.\n\n## Verified current state\n\n- `executeUnifiedSearch` (`packages/plugin/src/features/magic-context/search.ts`)\n computes `needsEmbedding`, starts `embedQuery(trimmedQuery, options.signal, \"query\")`\n (default `embedText` from `./memory/embedding`), then does `await Promise.resolve()`\n under the comment *\"Yield to the event loop so the embed fetch's request gets a\n chance to be dispatched\"*, then runs `resolveSearchWorkspaceContext(db, projectPath)`\n and `searchMessages({...})` synchronously, then `await queryEmbeddingPromise`.\n- `await Promise.resolve()` resumes after exactly **one** microtask hop.\n- Warm OpenAI-compatible chain: `embedText` awaits `provider.initialize()`;\n `OpenAICompatibleEmbeddingProvider.embed` awaits `embedBatch`; `embedBatch` awaits\n `this.initialize()` again before calling `fetch(\\`${this.endpoint}/embeddings\\`)`\n (`memory/embedding-openai.ts`). That is **2+ hops before `fetch` is invoked**.\n- Empirically confirmed with a throwaway script replicating that exact call shape\n (identical result under `bun` and `node`): after `await Promise.resolve()` the\n `fetch` call site had **not** been reached; after two microtask hops, or one\n `setTimeout(...,0)`, or one `setImmediate`, it had. These are hop counts, not timings.\n- Warm Synapse chain is strictly deeper: `SynapseEmbeddingProvider.embed` awaits\n `this.initialize()`, then `callWithRetry` calls `this.client.call(...)`, and\n `SubcClient.call` (`packages/plugin/src/shared/mc-host-client/client.ts`) itself\n awaits `managedRouteHandle` / `ensureConnection` before any socket write.\n- Cold paths are I/O-bound and out of reach of any local yield: Synapse\n `initialize()` performs a `models.list` round trip over the socket. OpenAI\n `initialize()` is synchronous (endpoint/model presence + SSRF check).\n- That `await Promise.resolve()` is the **only** pre-dispatch yield of its kind in\n `packages/plugin/src` (grep for `await Promise.resolve()` excluding tests), so\n this is a single-site root-cause fix, not a symptom patch.\n- No existing test asserts dispatch order. `search.test.ts` has\n *\"embeds the query exactly once even when memory + git_commit both need it\"*\n (count, not order).\n- Reusable macrotask-yield pattern already in repo, always as a file-local helper:\n `defer` + `yieldToEventLoop` in `message-index-async.ts` (`setImmediate` with\n `setTimeout(fn, 0)` fallback); plain `setTimeout(resolve, 0)` copies in\n `hooks/magic-context/module-state-sync.ts`, `hooks/magic-context/module-wire.ts`,\n `session-project-backfill.ts`; injectable `yieldToEventLoop` option in\n `claims-backfill.ts` and `v22-deferred-backfill.ts`.\n- Test seam already in repo: `countingDatabase` (`sql-counters.ts`) records every\n executed statement in order and is already imported by `search.test.ts`.\n- Baseline green: `bun test src/features/magic-context/search.test.ts` → 77 pass,\n 0 fail, 5.31s.\n\n## Minimal desired state\n\nIn `executeUnifiedSearch`, replace the single microtask yield with **one macrotask\nyield, taken only when `needsEmbedding` is true**. A macrotask boundary drains the\nentire microtask queue, so search.ts needs no knowledge of provider hop depth and\ngains no provider coupling. Copy the local `defer`/`yieldToEventLoop` shape from\n`message-index-async.ts` (`setImmediate` when present, else `setTimeout(fn, 0)`)\ninto `search.ts`; keep the existing comment, corrected to say *macrotask* and why.\n\nExplicitly out of scope: a shared yield module (5 local copies exist; consolidating\nthem is a separate task), a new `UnifiedSearchOptions` yield knob (no test needs\nit), eagerly awaiting `provider.initialize()`, provider edits, lane reordering,\nretry/polling changes.\n\n## Files\n\n- Edit `packages/plugin/src/features/magic-context/search.ts` — local yield helper +\n `executeUnifiedSearch`.\n- Edit `packages/plugin/src/features/magic-context/search.test.ts` — ordering regression.\n- Optional edit `packages/plugin/src/features/magic-context/memory/embedding-openai.test.ts`\n and `.../embedding-synapse.test.ts` — warm-path hop canaries.\n- Read-only: `memory/embedding.ts`, `memory/embedding-openai.ts`,\n `memory/embedding-synapse.ts`, `shared/mc-host-client/client.ts`, `sql-counters.ts`,\n `message-index-async.ts`, `hooks/magic-context/auto-search-runner.ts`.\n\n## Implementation steps\n\n1. Add the file-local `defer` + `yieldToEventLoop` helper to `search.ts`, mirroring\n `message-index-async.ts` verbatim in shape (no export, no options plumbing).\n2. In `executeUnifiedSearch`, replace `await Promise.resolve()` with\n `if (needsEmbedding) await yieldToEventLoop();`.\n3. Rewrite the adjacent comment: one microtask only advances the provider chain by\n one hop; both warm chains need more; a macrotask drains the microtask queue so\n dispatch is reached before the synchronous scan. State the cold-init limit.\n4. Leave `workspaceSpan` / `messageSpan` / `queryEmbeddingPromise` structure and all\n trace `dependsOn` wiring unchanged.\n5. Add tests below; run the commands section.\n\n## Test strategy (deterministic, no network, no timing assertions)\n\n- **Contract:** when a lane needs an embedding, the query embedding call reaches its\n transport dispatch point before `executeUnifiedSearch` executes its first\n synchronous SQLite statement.\n- **Failure class:** async-ordering regression — synchronous scan overtakes an\n in-flight embed whose chain needs N\u003e1 microtask hops.\n- **Oracle (independent, structural):** `countingDatabase(db).executions.length`\n observed from inside the injected `embedQuery` at its dispatch point. Zero\n statements executed ⇒ dispatch preceded all synchronous search SQL. No clocks,\n no elapsed-ms thresholds.\n- **Primary form:** parameterized unit test (`it.each` over hop counts) at the\n `unifiedSearch` boundary in `search.test.ts`:\n - seed memories/embeddings as existing tests do, then `counting.reset()`;\n - `embedQuery` = `async (text) =\u003e { for (let i = 0; i \u003c hops; i++) await Promise.resolve(); sqlAtDispatch = counting.executions.length; return vector; }`;\n - run `unifiedSearch(counting.db, ...)` with `memoryEnabled`, `embeddingEnabled`,\n `isEmbeddingRuntimeEnabled`, `readMessages`;\n - assert `sqlAtDispatch === 0` for `hops` ∈ {0, 1, 2, 3, 4}.\n - Pre-fix this fails for `hops \u003e= 2` and passes for 0–1 — verify that by running the\n new test against unmodified `search.ts` before applying the fix (guards against a\n vacuous test).\n- **Secondary form (recommended canaries, pin the real chains):**\n - `embedding-openai.test.ts`: pre-initialized provider, `spyOn(globalThis, \"fetch\")`\n returning a resolved stub response, call `provider.embed(\"q\", undefined, \"query\")`\n without awaiting, `await new Promise((r) =\u003e setImmediate(r))`, assert\n `fetchSpy` was called. Documents the hop depth this fix depends on.\n - `embedding-synapse.test.ts`: reuse `MockSynapseClient` + `clientFactory`, await\n `provider.initialize()` first (warm path), then the same one-macrotask assertion on\n `client.call` having been invoked with `embed.query`.\n- **What a green run establishes:** for the executions exercised, no synchronous search\n statement ran before embed dispatch, and the warm provider chains reach transport\n within one macrotask. It establishes nothing about wall-clock latency, cold init,\n real socket flush completion, host queueing, or provider-side scheduling.\n- **Known gaps (record, do not chase here):** cold-init round trips still serialize\n ahead of `embed.query`; `SubcClient` write flush completion is not asserted, only\n `call` invocation; no coverage of a runtime lacking both `setImmediate` and timers.\n\n## Benchmark claim boundaries\n\nThis task ships a **structural ordering fix and no performance claim**. Do not put a\nlatency number in the commit message, task notes, or PR body from ad-hoc runs.\n\nIf a latency claim is wanted, it is a separate task and must first fix the claim via\n`/quantitative-analysis:statistics-and-benchmarking-discipline`: outcome =\nlogical-request latency of `unifiedSearch` (call → results) plus embed-dispatch offset;\ntiming boundary and terminal outcomes (success / abort at 3s / provider failure) both\nreported, timeouts never dropped; workload = warm provider, long-session corpus with a\nstated message/memory count; warm vs cold reported separately; single-operation\nmicrobenchmark (no arrival model) or trace replay, declared explicitly; report p50/p99/p99.9\nplus eCDF with observation and independent-run counts. Then\n`/quantitative-analysis:benchmark-experiment-design` fixes unit roles (process-level\nreplication, not iteration count), assignment/order, A/A control, power, and a\npredeclared stopping rule before any number is read. Reuse the `magic-context-515`\nbaseline as the comparison artifact. Forbidden: \"3s → Xms\" hero numbers, one-run\nbefore/after, mean-only reporting, and reusing correctness tests as performance evidence.\n\n## Required skill sequence and conditional handoffs\n\n1. `/implementation:typescript-implementation` — write the yield helper and the guarded\n call; keep the diff minimal and idiomatic to the surrounding file.\n2. `/testing:test-strategy` — already applied; its deliverable is the section above.\n Re-enter only if the ordering oracle above proves unobservable.\n3. Conditional — if anyone proposes extracting a shared yield util, adding an options\n knob, or generalizing the yield: `/code-quality:reduce-complexity` first; default is\n \"no new abstraction\" (no second current call site).\n4. Conditional — if a latency claim enters scope: statistics-and-benchmarking-discipline\n then benchmark-experiment-design, in that order, before collecting data.\n5.

| {"_type":"issue","id":"magic-context-s64","title":"Reduce Synapse query and polling tail amplification","description":"## Problem\n`SynapseComponent::handle_query` (`crates/mc-host/src/synapse/mod.rs`) admits queries with\n`query_admission.try_acquire_owned()` on a **1-permit** semaphore: fail-fast, no queue, no wait.\nThe second concurrent query gets `queue_full` (\"query admission capacity is exhausted\"). That error\ncarries **no `retry_after_ms`**, so the client's `classifyError`\n(`packages/plugin/src/features/magic-context/memory/embedding-synapse.ts`) stamps the constant\n`100` ms default from `SynapseEmbeddingError`. `callWithRetry` then retries `embed.query`+`queue_full`\nuntil the request deadline (`retryQueryAdmission` bypasses the generic `attempt \u003e= 3` cap) with an\n**unjittered** delay. N concurrent queries therefore synchronize on a 100 ms grid and tail latency is\n≈ 100 ms × queue position, against a sub-millisecond transport floor (memory\n`embedding-machinery-baseline-21bd53d0`, `docs/perf/mc-host-baseline.md`).\nBatch path: `handle_batch` replies `protocol::job_descriptor_body(..., \"queued\", retry_after_ms)` and\n`handle_result` replies `protocol::pending_body(..., retry_after_ms)` with `SynapseLimits.retry_after_ms\n= 50`. Client `pollBatch` and `collectJobPages` issue the first `embed.result` immediately. That poll\nraces the worker: a fast job can already be ready, but a pending reply forces `pendingPollDelay` =\nclamp(served `retry_after_ms` ?? 50, ≥ 10 ms, remaining deadline). The measured failure is therefore a\n50 ms latency quantization on the subset that lose this race, not one guaranteed wasted poll per job.\nGoal: remove the 100 ms retry staircase and the 50 ms poll quantization **without** weakening finite\nbounds, deadlines, cancellation, or overload rejection.\n## Vocabulary (mandatory in every measurement)\n- **logical request**: one caller-level operation — one `embedQuery`, or one page's `embed.batch` plus\n its `embed.result` sequence to completion.\n- **attempt**: one wire call (`embed.query`, `embed.batch`, `embed.result`), including retries and polls.\n- **offered rate** λ_off: logical requests started per second by the generator (open loop: intended\n start times, not achieved).\n- **admitted rate** λ_adm: attempts that acquire an admission permit / job slot.\n- **completed rate** X: logical requests returning vectors.\n- **rejected rate**: attempts answered `queue_full`, split per method and per code.\n- **timed-out rate**: logical requests ending `timeout` (client deadline, or host `QueryFault::Timeout`).\n- **service time S**: host busy time holding the `cpu` permit for one attempt (engine `embed` call);\n measured separately for the tiny engine and the real bundle, with CV reported.\n- **retry amplification A** = attempts / logical requests, per method; also report the poll-count\n distribution per job.\n- **Accounting invariant** checked every run: `λ_off = X + terminal rejections + timeouts ± in-flight`.\n A rep that violates it is discarded as an instrumentation bug, not reported as a result.\n## Skill ownership (in order)\n1. `/quantitative-analysis:statistics-and-benchmarking-discipline` — pin environment and commit,\n define warm/steady state, logical outcomes, workload and arrival model, target population,\n quantiles/eCDF, goodput, and coordinated-omission-free scheduled-send timing.\n2. `/quantitative-analysis:benchmark-experiment-design` — pre-register factors, levels, hypotheses,\n analysis units, expected direction, effect boundary, assignment, A/A control, independent block\n count, uncertainty construction, multiplicity, and stopping before treatment collection.\n3. `/quantitative-analysis:queueing-theory-for-engineers` — classify today's design as a **loss**\n system (M/M/1/1, Erlang-B blocking) versus candidate **waiting** systems (M/M/1/K); Little's law\n (N = X·R) as a cross-check; ρ = λ_adm·S; never fit open-model formulas to closed-loop data.\n4. `/quantitative-analysis:usl-scalability-analysis` — only after the gate below is satisfied.\n5. `/performance:load-test-harness` — open-loop generator at fixed λ for saturation and rejection\n curves; generator outside the SUT process; no back-pressured request generation.\n6. `/systems-design:bounded-design` — every new queue or wait finite and typed; rejection stays a\n first-class outcome; no unbounded waiters, memory, or attempts.\n7. `/systems-design:retry-backoff-jitter` — attempt budget, deadline-aware retries, decorrelated/full\n jitter, server-supplied `retry_after_ms` authoritative, retry budget so A stays bounded under\n sustained overload.\n8. `/performance:perf-pipeline` — baseline → profile → single hypothesis → minimal change → verify on\n the same harness → regression guard.\n## Candidate designs (do not select before data)\n- **A. Server bounded waiting** — replace `try_acquire_owned` with a deadline-aware bounded acquire\n (`max_waiting_queries`), still `queue_full` beyond K. Converts loss to M/M/1/K; removes the client\n retry loop from the common path.\n- **B. Jitter + honored `retry_after_ms`** — host stamps `retry_after_ms` on `queue_full`; client\n applies decorrelated jitter. Smallest diff; keeps loss semantics, only desynchronizes.\n- **C. Fast-first escalating polls** — first `embed.result` after ~1–2 ms, escalating (e.g. ×1.6)\n capped at the served `retry_after_ms`, deadline-clamped, with a busy-poll floor.\n- **D. Bounded server-side wait on `embed.result`** (long poll ≤ min(client deadline, host cap)) —\n requires handler-permit accounting (`max_handler_tasks` in `crates/mc-host/src/config.rs`, reserved\n permits in `crates/mc-host/src/handler.rs` / `runtime.rs`) so held pollers cannot starve other routes.\n- **E. Completion push/notification** — out of scope unless A–D miss the target; note the protocol cost.\nCombinations (A+C, B+C) are allowed. Selection is decided by the acceptance criteria, not assumed.\n## Model validity\n- Do not fit Erlang loss/waiting models from closed-loop client data, and do not fit USL from open-loop\n offered-load data. Each model consumes only the population and units allowed by its skill contract.\n- Measure service-time CV. Tiny engine ≈ deterministic; the real bundle varies with batch size. If\n CV ≫ 1, state that M/M/* is bound-shaped approximation only and prefer measured curves; use M/G/1\n (Pollaczek–Khinchine) intuition for the *direction* of variance effects.\n- The CPU lane is a single server with batch service (`cpu = Semaphore::new(1)`). If\n `magic-context-ioi` makes inference concurrency configurable, every model here must be re-derived —\n record the dependency, do not assume c = 1 permanently.\n## Finite bounds (bounded-design contract)\nAny accepted design must preserve and prove finite resource use. If bounded server waiting is selected,\nits waiter count and maximum wait become startup-validated limits; a loss-system design keeps immediate\nrejection. In either case wait never exceeds request deadline or host cap; unchanged existing limits (`max_queued_jobs` 64,\n`max_queued_request_bytes` 64 MiB, `max_retained_jobs` 64, `max_retained_result_bytes` 64 MiB,\n`max_batch_items` 64, `max_text_bytes` 1 MiB, `max_page_vectors` 16, `max_page_encoded_bytes` 2 MiB,\n`retention` 15 min); `queue_full` still returned once the new bound is exceeded — never silent\nunbounded queueing; resident-byte accounting still dominant, since a *waiting* query holds its\n`text_charge`, so `max_waiting_queries × max_text_bytes` must fit the resident budget enforced by\n`owned_input_bytes` / `shrink_covered` / `ByteCharge`; client attempt and poll counts bounded even at\nthe 120 s batch deadline.\n## Cancellation / deadline invariants\nThese are why `handle_query`'s `tokio::select!` is `biased` with `closing.cancelled()`, `tx.closed()`,\nand `sleep_until(deadline)` arms, and they must still hold: host shutdown cancels queued-but-unstarted\nwork and closes admission; a vanished waiter (route loss or deadline) costs zero engine work while the\ncall is only queued; a started native call runs to completion holding its permit and charge;\n`AbandonGuard` still publishes `internal_error` if a worker unwinds before publication;\n`deadline_ms.unwrap_or(protocol::MAX_DEADLINE_MS)` remains the ceiling — no design waits past it;\nclient absolute deadlines in `callWithRetry`, `pollBatch`, `collectJobPages` stay single-deadline (no\nper-attempt extension) and the `Date.now() + delay \u003e= deadlineAtMs` short-circuit stays; handling of\n`idempotency_conflict`, `module_restarted`, and `outcome_unknown` is unchanged — no new retry class\nfor non-idempotent sends.\n## Benchmark matrix — tiny engine (hermetic, primary)\nSUT: real host plus the deterministic `EmbeddingEngine` double used by\n`crates/mc-host/tests/synapse_protocol.rs` and `synapse_jobs.rs`.\n- closed-loop concurrency: 1, 2, 4, 8, 16 simultaneous `embed.query`\n- open-loop offered rate: λ at 0.25×, 0.5×, 0.75×, 1.0×, 1.5×, 2× of estimated capacity 1/S\n- design variant: baseline, A, B, C, D, A+C\n- injected service time: ~0 ms, 5 ms, 25 ms (separates queue effect from engine cost)\n- batch shape: 1 page × 16 items, 4 pages × 16 items (cursor paging), one 64-item job\nPer cell: attempt and logical-request latency quantiles, X, rejected and timed-out rates, A, poll-count\ndistribution, permit wait time, host CPU time and wakeup/syscall counts (evidence for \"no busy-poll\").\nRun pilot blocks to estimate process-level variance and queue accumulation, then freeze the independent\nblock count and hold duration through `/benchmark-experiment-design`; randomize complete cell order and\nretain invariant-violating attempts as invalid evidence rather than silently replacing them.\n## Benchmark matrix — production bundle (confirmatory)\nReal certified bundle and ORT via `SynapseConfig`, one pinned machine and commit; concurrency 1/4/8;\nbaseline versus the single chosen variant; 16- and 64-item batches. Use the frozen independent block\ncount from the experiment design. Purpose: confirm the tiny-engine mechanism survives realistic S\n(where S may dominate queueing delay) and report any end-to-end throughput or resource shift.\n## USL applicability gate\nFit USL (σ, κ) **only if all** hold: at least six closed-loop concurrency levels (for example\n1,2,3,4,8,16) with fixed per-request work and independent repeats; throughput measured with **zero**\nrejections and **zero** timeouts in-window (a loss\nsystem's X is not a scalability curve); service time stationary across levels (median and CV within\ntolerance); ≥5 reps per level with CIs. Otherwise record \"USL not applicable — \u003creason\u003e\" and stop at\nmeasured curves. USL is diagnostic only; the decisive regime here is admission/loss, so USL must not be\nthe primary acceptance evidence.\n## Deterministic tests (no wall-clock flake)\n- Rust `crates/mc-host/tests/synapse_protocol.rs`: N concurrent queries yield success or `queue_full`\n **with** a stamped `retry_after_ms`; the bounded waiter limit rejects the N+1st; deadline expiry while\n waiting returns `timeout` with **zero** engine calls (assert a call counter); shutdown while waiting\n returns `cancelled`. Use `tokio::time` pause/advance, not real sleeps.\n- Rust `crates/mc-host/tests/synapse_jobs.rs`: pending replies still carry `retry_after_ms`; a long-poll\n variant returns by cap and never holds a handler permit past the deadline.\n- TS `packages/plugin/src/features/magic-context/memory/embedding-synapse.test.ts` with fake timers:\n server `retry_after_ms` honored over the client default; jitter bounded in [base, base×k] and distinct\n across concurrent callers under a seeded RNG; attempt and poll counts bounded; first poll fast then\n escalating; no interval below the busy-poll floor; deadline never exceeded;\n `idempotency_conflict`/`module_restarted` still not retried.\n- Unchanged transport suites stay green: `packages/plugin/src/shared/mc-host-client/{client,connection,deadline}.test.ts`\n (`writer_queue_full` semantics untouched).\n## Evidence sources (benchmark and wire outcomes only)\nThis task has **no production metrics dependency**. `magic-context-a52` (host metrics contract) is\nsuperseded; do not wait on it and do not add a metrics framework or host counters here. All evidence\ncomes from harness-side wire accounting: logical requests, attempts, retries, polls, terminal\noutcomes, and coordinated-omission-free scheduled-send latency, plus process-level resource series\n(`/proc/\u003cpid\u003e/status`, `/proc/\u003cpid\u003e/stat`). PR #41 provides the open-loop scheduled-send\ngenerator and terminal-accounting harness (merge it before starting), but it only covers the zero-delay `embed.query` path —\nthe batch/poll (`embed.batch` + `embed.result`) harness path must still be built in this task, and\nno improvement claim is final until the real-bundle confirmatory run (gated on `magic-context-c50.8`).\n## Files / symbols in scope\n- `crates/mc-host/src/synapse/mod.rs`: `SynapseLimits`, `SynapseInner.{cpu, query_admission, tracker,\n closing}`, `handle_query`, `QueryFault`, `handle_batch`, `spawn_batch_worker`, `AbandonGuard`,\n `handle_result`, `app_error`, `owned_input_bytes`, `shrink_covered`.\n- `crates/mc-host/src/synapse/jobs.rs`, `protocol.rs`: `JobTable::{admit_charged,start,poll,\n publish_ready,publish_failed,sweep}`, `AdmitOutcome`, `PollOutcome`, `job_descriptor_body`,\n `pending_body`, `MAX_DEADLINE_MS`.\n- `crates/mc-host/src/{config.rs,runtime.rs,handler.rs,wire.rs}`: `max_handler_tasks`, reserved\n permits, `ByteCharge` — touched only if a waiting or long-poll design holds permits.\n- `packages/plugin/src/features/magic-context/memory/embedding-synapse.ts`: `SynapseEmbeddingError`\n (100 ms default), `classifyError`, `pendingPollDelay`, `callWithRetry` (`attempt \u003e= 3`,\n `retryQueryAdmission`), `pollBatch`, `collectJobPages`, `SYNAPSE_DEFAULT_QUERY_TIMEOUT_MS`,\n `SYNAPSE_DEFAULT_BATCH_TIMEOUT_MS`.\n- Docs on landing: `docs/mc-host-wire-protocol.md` (retry/wait semantics), a new `docs/perf/` run record.\n- Baseline evidence: memory `embedding-machinery-baseline-21bd53d0`, `docs/perf/mc-host-baseline.md`.\n## Related work\n\n- `magic-context-a52` is **superseded** (no longer a blocker): the host metrics contract was dropped.\n Its PR #41 open-loop query baseline harness (scheduling + accounting) is kept and reused here;\n PRs #42-#44 (host metrics core/tests/docs) were closed unmerged.\n- `magic-context-c50.8` blocks production-bundle confirmation and pins runtime packaging.\n- `magic-context-ioi` is related: any concurrency topology changes the queue model and requires re-derivation.\n- `magic-context-09u` owns pre-dispatch ordering, not host admission or polling.\n- `magic-context-18r` and `magic-context-chj` change service demand and must be recorded in every run manifest.\n- `magic-context-515` is the closed originating audit and baseline memory.\n\n## Stop conditions\nStop and report — do not keep tuning — when any holds: the chosen variant meets acceptance on the tiny\nengine and is confirmed on the bundle; the frozen reporting contract shows queueing is not material\nfor the target population (remaining cost is engine-bound → `magic-context-ioi` / `magic-context-18r`); a\nvariant needs an unbounded queue, unbounded waiters, or a deadline extension to hit the target (reject\nit and record why); the accounting invariant cannot be satisfied (fix instrumentation first); the target\nrequires the push/notification protocol change (spin a separate task).\n## Acceptance criteria (measurable)\n1.

There was a problem hiding this comment.
This daemon-command task has only a parent-child edge, so it is immediately ready alongside K1 even though its acceptance criteria require the commit envelope and admission state from K2/K6 plus daemon and thin-client routing from K8. The same omission affects the newly reparented 62w and 8y6 tasks, which likewise consume kernel facilities but have no blocking edges; wire these tasks to the kernel children that provide their required APIs so implementers are not sent into unavailable machinery.

There was a problem hiding this comment.
Keeping 3q5.4 and 3q5.5 untouched leaves the mandatory retrieval gate defined around claim, claim-revision, and simulated claims-migration identities, even though this plan replaces those objects with kernel propositions, decisions, observations, and evidence and later deletes the claims layer. Because downstream ranking, model, layout, and ANN work must pass U5, kernel-era results will either be rejected by the gate or require the legacy adapter this plan forbids; move these benchmark tasks into the rewrite set and define their labels against stable kernel identities.

Summary
The backlog now describes one daemon-authoritative semantic-memory architecture. It replaces contradictory compatibility, mirror, and TypeScript fallback work with a semantic-kernel epic and a separate retrieval lane built on kernel stores.
This PR restructures planning and task authority only. Kernel implementation remains follow-up work under
magic-context-kh8and the rewrittenmagic-context-3q5epic.Key decisions
magic-contextdis the only memory writer and semantic authority. Thin clients report memory unavailable when the daemon is down.core.sqliteand content-addressedartifacts/;search.sqliteandvectors/are rebuildable projections.Session-settled decisions carried from planning: no memory-domain migration or compatibility lane (user-directed); mandatory daemon authority and the adopted semantic-kernel outline (user-approved/user-directed).
Validation
bd list --tree --all --limit 0shows 14 new kernel children and four reparented tasks undermagic-context-kh8.bd dep cyclesreports no dependency cycles.bd readyincludesmagic-context-kh8.1and no bead closed by this plan.Code review: skipped (mechanical diff). The change contains generated Beads metadata and its planning authority document, with no runtime behavior.
Post-Deploy Monitoring & Validation
No additional operational monitoring required. This PR changes task metadata and planning documentation only.
