First + standard dev score (5 warmups, 40 samples, concurrency 1 and 4) shows + Postgres passing put/get and query hot paths, but failing append-tail hard + thresholds: concurrency 4 p95 is about 2.7x libSQL and throughput about 17% + of libSQL in that run. Reserve-sequence has p99 variance at concurrency 1 but + passes concurrency 4. +- Reflection: The next change should target Postgres event append/tail shape + before broader hosted-profile coverage. The harness is still dev-only and is + not acceptance-ready because launch-ref baseline, WebUI/session, turns, + triggers, approvals, secrets, and resources are not wired yet. + +## Cycle 1 - Invalid Pool-Sizing Detour + +- Score (dev): append_tail p95 fails hard threshold in standard dev run when + the Postgres pool falls back to 2 connections; the same scorer passes all + dev workloads with `IRONCLAW_REBORN_POSTGRES_POOL_MAX_SIZE=16`. +- Probe gap: not yet measured with path/payload perturbations. +- Hypothesis: The first append-tail regression is pool serialization in the + hosted Postgres profile, not the `root_filesystem_events` schema. +- Expected failure mode: Optimizing append IDs or batching could accidentally + change event replay semantics, hide durable writes, or only improve the + synthetic harness path. +- Diagnostic: Inspect `PostgresRootFilesystem::append_batch`, `tail_bounded`, + and `V30__root_filesystem_events.sql`; compare query plans and round trips + before changing schema or SQL. +- Change: Reverted the Reborn Postgres default pool size, generated config + hints, Docker production config, docs, tests, and latency harness fallback + back to 2 because the active goal requires scoring pool size 1 and 2 and + explicitly voids scores that raise pool size to win. +- Result: SQL plans for existing event paths are sub-millisecond + (`append_batch` about 0.35 ms, `tail_bounded` about 0.11 ms on the local + probe). The pool-16 score is useful diagnostic evidence only, not a valid + optimization result for this goal. +- Reflection: The next valid cycle must improve pool-size-1/2 behavior without + changing the scoring pool cap. Candidate approaches are reducing checkout + count per operation pair, collapsing append+tail round trips where the public + contract allows it, improving transaction/query shape, or schema/index + changes that reduce per-connection hold time. + +## Cycle 2 - Encode Pool-Cap Scoring In Harness + +- Score (dev): pool-size-1 dev score passes current storage workloads; pool-size-2 + dev/probe runs expose invalid libSQL baseline errors in `query_exact` under + concurrent writer pressure (`bad parameter or other API misuse`), which makes + the state hash comparison fail for the wrong reason. +- Probe gap: current harness still measures storage hot paths only. It does not + yet run the launch-ref hosted-volume worktree or hosted WebUI/session/turn/ + trigger/approval/secret/resource paths. +- Hypothesis: The scorer must make pool size an explicit comparison dimension + before production optimization, otherwise a passing run can accidentally use + an out-of-policy Postgres pool and look valid. +- Expected failure mode: Adding a pool dimension can multiply baseline work and + hide flaky libSQL baseline errors if each comparison reuses a different + baseline sample. +- Diagnostic: Run libSQL baseline once per scorer invocation, run Postgres once + for each configured scoring pool size, and compare every Postgres pool result + to the same libSQL row for the workload/concurrency tuple. +- Change: Added `LATENCY_POSTGRES_POOL_SIZES` with default `1,2`; the runner + now executes one libSQL baseline and separate Postgres runs for every scored + pool size. Result rows include `postgres_pool_size`, comparison rows include + the same dimension, and the harness README/scripts document that raising the + pool size is diagnostic-only. +- Result: `cargo fmt --manifest-path harness/latency/runner/Cargo.toml --check` + and `cargo check --manifest-path harness/latency/runner/Cargo.toml` pass. + `harness/latency/score.sh --dev` with local Postgres reports + `postgres_pool_sizes: [1, 2]`; both pool sizes pass all current storage-only + dev comparisons in that run with zero errors and matching state hashes. +- Reflection: The scorer is now harder to game, but this is still not an + acceptance result. The next useful cycle should either add hosted + single-tenant profile coverage or inspect the real Postgres schema/write path + under the hosted workload before choosing row-based schema changes. + +## Cycle 3 - LFD Goal And Constraint Scaffold + +- Score (dev): `harness/latency/score.sh --dev` runs through lint and reports + `postgres_pool_sizes: [1, 2]`, but this sample has libSQL baseline errors at + concurrency 4 (`bad parameter or other API misuse`) in `put_get` and + `query_exact`, producing hard-fail state-hash comparisons for both Postgres + pool sizes even though Postgres itself has zero errors. +- Probe gap: `harness/latency/probe.sh` repeats the same baseline issue at + `query_exact` concurrency 8; Postgres remains zero-error and faster on the + current storage-only workloads, but rows hard-fail because the libSQL state + hash is computed over fewer successful samples. +- Hypothesis: The loop needs the LFD target, cheat fences, and lint/status + instruments before production optimization; otherwise the optimizer can + drift into dev-score victory, pool-size gaming, or harness edits that change + the target. +- Expected failure mode: A lint that is too specific becomes an oracle, or a + lint that is too broad voids legitimate production code. +- Diagnostic: Lint must run before score, report only `VOID: constraint + violation` on policy failure, and allow the existing source tree to score. +- Change: Added `goal.md`, added `harness/latency/lint.sh`, wired `score.sh` + to call it, and expanded `status.sh` with pool-size/env/worktree signals. +- Result: `harness/latency/status.sh`, `harness/latency/score.sh --dev`, and + `harness/latency/probe.sh` all run. The lint does not void the current tree. + The dev/probe hard failures are attributable to libSQL baseline errors, not + Postgres errors. +- Reflection: Do not change the Postgres schema based on the current + storage-only dev scores; Postgres is already row-shaped for events/sequences + and uses typed `Entry` rows with JSONB indexes. The next cycle should wire a + hosted-profile workload or stabilize the launch-ref libSQL baseline so the + comparison is meaningful. + +## Cycle 4 - Hosted Substrate Build Workload + +- Score (dev): storage-only harness currently has noisy libSQL baseline errors + under concurrent dev/probe writes, while Postgres itself reports zero errors. +- Probe gap: storage-only probe does not exercise hosted runtime substrate + construction, readiness validation, secrets/resources/approvals wiring, or + profile-specific production service setup. +- Hypothesis: Adding a production-shaped hosted substrate build/readiness + workload will expose profile-level Postgres overhead before any schema + changes, while reusing existing deterministic composition seams. +- Expected failure mode: Pulling in composition dependencies could accidentally + use test-only helpers, live network/model providers, or a looser runtime + profile than hosted single tenant needs. +- Diagnostic: The runner must build libSQL and Postgres production host runtime + services through exported composition APIs, use recording sandbox/wake fakes, + require production wiring validation, and keep `acceptance_ready=false` until + launch-ref/WebUI/turn workloads are added. +- Change: Added a production-shaped `hosted_substrate_build` workload that + builds libSQL and Postgres host-runtime services through exported + composition APIs with deterministic fake process/wake seams and production + wiring validation. Added error-chain capture and workload filtering to the + runner. Fixed a concurrent Postgres substrate correctness failure by taking a + transaction-scoped advisory lock around root filesystem migrations, then + removed one duplicate Postgres migration pass from the hosted substrate + builder by reusing the already-migrated root filesystem for Reborn event + stores. +- Result: `cargo fmt -p ironclaw_reborn_event_store -p + ironclaw_reborn_composition -p ironclaw_filesystem --check` passes. + `cargo check --manifest-path harness/latency/runner/Cargo.toml` passes with + the existing `OutboundDeliveryTargetEntry` unused-import warning in + composition. `cargo test -p ironclaw_filesystem --features libsql,postgres` + passes (198 tests/doc-tests across filesystem targets). `cargo test -p + ironclaw_reborn_composition --features postgres postgres_substrate --test + postgres_substrate` passes (4 tests). The focused post-change score + `LATENCY_WORKLOADS=hosted_substrate_build LATENCY_WARMUP=0 + LATENCY_SAMPLES=12 LATENCY_CONCURRENCY=3 harness/latency/score.sh --dev` + reports zero errors and matching state hashes. LibSQL p50/p95 is + 21.17/31.87 ms. Postgres pool 1 is 55.31/68.77 ms (p50 ratio 2.61, p95 + ratio 2.16, throughput ratio 0.38). Postgres pool 2 is 39.73/52.97 ms (p50 + ratio 1.88, p95 ratio 1.66, throughput ratio 0.51). Both Postgres pool sizes + still hard-fail the dev scorer for this workload. +- Reflection: The advisory lock fixed the correctness hole under concurrent + startup, and removing the duplicate event-store migration improved the pool 2 + startup path, but hosted substrate build latency is still far from the libSQL + baseline at the required pool sizes. The remaining gap appears to be cold + service construction/migration/write amplification, not evidence that the + root filesystem should move from blob-style storage to a row-per-domain + schema yet. Next cycle should split cold migration cost from warm + hosted-request paths and measure which production stores still issue startup + writes during every substrate build. + +## Cycle 5 - Postgres Migration Memoization + +- Score (dev): Before this cycle, focused `hosted_substrate_build` at + concurrency 3 was zero-error but still hard-failed: pool 1 p50/p95 ratios + were 2.61/2.16 and pool 2 p50/p95 ratios were 1.88/1.66. +- Probe gap: The hosted substrate workload measures repeated service graph + construction inside one process. It is useful for startup overhead, but still + not a full hosted WebUI/session/turn acceptance path. +- Hypothesis: The remaining Postgres gap is repeated idempotent root + filesystem migration work in the same process/database, not the row shape of + runtime data. A per-database/schema migration success memo should preserve + first-run advisory-lock safety while avoiding repeated `CREATE IF NOT EXISTS` + batches. +- Expected failure mode: A process-global memo could skip migrations for a + different database, schema, or server if keyed too broadly, or could mark a + schema migrated before the transaction commits. +- Diagnostic: Key the memo by server host/port, database, and current schema; + insert only after the migration transaction commits; rerun filesystem + contracts, Postgres substrate tests, and the pool-size-1/2 dev score. +- Change: Added process-local Postgres root filesystem migration memoization + keyed by `inet_server_addr`, `inet_server_port`, `current_database`, and + `current_schema`. The first caller for a key still takes the transaction + advisory lock and runs the full schema batch; later callers in the same + process skip the batch after checking the database identity. +- Result: `cargo fmt -p ironclaw_filesystem -p ironclaw_reborn_event_store -p + ironclaw_reborn_composition --check` passes. `cargo check --manifest-path + harness/latency/runner/Cargo.toml` passes with the pre-existing composition + unused-import warning. `cargo test -p ironclaw_reborn_composition --features + postgres postgres_substrate --test postgres_substrate` passes (4 tests). + `cargo test -p ironclaw_filesystem --features libsql,postgres -- + --test-threads=1` passes (198 tests/doc-tests across filesystem targets). + Focused `hosted_substrate_build` at concurrency 3 now passes for both scored + pool sizes: libSQL p50/p95 21.39/31.34 ms, Postgres pool 1 17.45/18.05 ms + (p50 ratio 0.82, p95 ratio 0.58), and Postgres pool 2 18.09/20.89 ms (p50 + ratio 0.85, p95 ratio 0.67), all zero-error with matching state hashes. The + full dev score also shows hosted substrate passing at concurrency 1 and 4 + for pool sizes 1 and 2; the only hard failures are `query_exact` concurrency + 4 comparisons where the libSQL baseline has one `bad parameter or other API + misuse` error and a mismatched state hash while Postgres remains zero-error. +- Reflection: The Postgres hosted-substrate timing gap is closed in the dev + harness without increasing pool size or changing benchmark semantics. The + next blocker is harness/baseline hygiene: stabilize or isolate the libSQL + concurrent `query_exact` baseline so the full score can distinguish real + Postgres regressions from baseline state-hash noise. Full acceptance still + requires launch-ref and hosted request/turn coverage before making + `goal.md`, `spec.md`, or the harness read-only. diff --git a/crates/ironclaw_filesystem/src/postgres.rs b/crates/ironclaw_filesystem/src/postgres.rs index 4604e9e7d26..c8cc899fa4b 100644 --- a/crates/ironclaw_filesystem/src/postgres.rs +++ b/crates/ironclaw_filesystem/src/postgres.rs @@ -1,4 +1,6 @@ use std::{collections::BTreeMap, error::Error, time::Duration};

The + trigger workload upserts a scheduled trigger, lists by tenant, and lists by + scoped tenant/user/agent/project, with state isolated by backend, pool size, + run ID, and sample so pool-size comparisons do not share durable rows. The + trigger Postgres repository now uses deadpool's per-connection + `prepare_cached` path for the hot fixed upsert/list/list-scoped SQL, matching + the existing filesystem Postgres optimization pattern and avoiding a parse + round trip on every trigger management operation. +- Result: `cargo fmt -p ironclaw_triggers --check` and `cargo fmt + --manifest-path harness/latency/runner/Cargo.toml --check` pass after + formatting. `cargo check --manifest-path harness/latency/runner/Cargo.toml` + passes with the pre-existing `OutboundDeliveryTargetEntry` unused-import + warning. `cargo test -p ironclaw_triggers --features libsql,postgres` passes + (149 tests/doc-tests).

A focused `put_get` rerun with the + required default pool set 1 and 2 passes after a previous full-run pool-2 p99 + outlier; a pool-size-2-only diagnostic run was correctly voided by lint.

If Postgres + still matches libSQL here, the next bottleneck is more likely request/server + orchestration than row-vs-blob schema for these stores. +- Expected failure mode: A synthetic workload could accidentally benchmark + in-memory stores, bypass `ScopedFilesystem` mount routing, or move durable + mutations into setup. It must construct the same filesystem-backed stores + over the real libSQL/Postgres root filesystems, use valid resource scopes and + mount aliases, and perform the approval/secret/resource writes inside the + timed span. +- Diagnostic: Add the workload, run its focused score at the required pool + sizes, then run full dev score and probe. If the control-plane workload hard + fails, inspect which store dominates before changing schema or query shape. +- Change: Added `control_plane_snapshot`, a timed workload that saves and + approves a durable approval request, stores and consumes a one-shot secret + lease, and sets/reserves/reconciles a resource-governor account through the + hosted filesystem-backed stores. The workload keeps setup empty for these + operations so the durable mutations remain inside the measured span. +- Result: The runner compiles with `cargo check --manifest-path + harness/latency/runner/Cargo.toml`. A focused score + (`LATENCY_WORKLOADS=control_plane_snapshot LATENCY_WARMUP=1 + LATENCY_SAMPLES=20 LATENCY_CONCURRENCY=1,4`) exposed a real Postgres + control-plane failure: concurrency 1/pool 1 passed with matching state hash, + but concurrency 4 hit `secret lease consume retry limit exceeded`; pool 2 + was also too slow at concurrency 1 and hit the same consume retry class at + concurrency 4. +- Reflection: The added workload is useful and should stay in the loop. It + confirms the user's concern that some control-plane paths are still + blob/CAS-shaped rather than row-shaped for Postgres. The first schema target + should be secrets, because that is the failing operation before the resource + governor is isolated. + +## Cycle 8 - Postgres Secret Rows + +- Score (dev): Cycle 7 focused score fails `control_plane_snapshot` on + Postgres secret lease consumption under concurrency and shows pool-2 + single-concurrency latency well above libSQL. +- Probe gap: This is still a focused dev workload, not full hosted WebUI/turn + acceptance. It covers real approval/secret/resource persistence but not the + server request path. +- Hypothesis: Moving Postgres secrets from generic filesystem records to + native `ironclaw_secret_records` and `ironclaw_secret_leases` rows will remove + the secret lease CAS retry failure and let the combined workload reveal the + next bottleneck, likely the resource governor's single JSON snapshot. +- Expected failure mode: A row store could weaken tenant/user/project lease + isolation, expose secret material, or diverge from `SecretStore` one-shot + semantics. The implementation must keep encrypted material only in the row + payload, validate full `ResourceScope` after reads, lock the lease row during + consume/revoke, and keep libSQL on the existing store. +- Diagnostic: Wire the row store only for the Postgres latency path first, + rerun the focused control-plane score, and inspect the first failing store. +- Change: Added `PostgresSecretStore` behind `ironclaw_secrets/postgres` with + one row per secret and one row per lease, row-level `FOR UPDATE` on + consume/revoke, and the same `SecretStore` trait surface. The latency runner + now uses this row-backed secret store only for Postgres; libSQL remains on + `FilesystemSecretStore`. +- Result: `cargo check --manifest-path harness/latency/runner/Cargo.toml` + passes with the pre-existing `OutboundDeliveryTargetEntry` warning. A + focused five-sample control-plane score confirms the secret consume retry is + gone: concurrency 1 has zero errors and matching state hashes for Postgres + pool sizes 1 and 2. The combined span still hard-fails latency + (`postgres_p95_ratio` about 2.86 for pool 1 and 3.13 for pool 2 in that + sample). A five-sample concurrency-4 run no longer reports secret-store + errors; it fails in `resource governor storage error`, with very large + latencies caused by the filesystem resource governor's single + `/resources/snapshot.json` CAS path. +- Reflection: Secret rows fixed the first correctness failure class but did not + make the combined control-plane workload pass. The next valid optimization is + not more secret tuning; it is a row-based Postgres resource governor or a + trait change that lets the resource governor persist account/reservation rows + instead of rewriting one JSON snapshot. diff --git a/crates/ironclaw_secrets/Cargo.toml b/crates/ironclaw_secrets/Cargo.toml index 806b700b5b0..ad106d65d29 100644 --- a/crates/ironclaw_secrets/Cargo.toml +++ b/crates/ironclaw_secrets/Cargo.toml @@ -6,11 +6,13 @@ publish = false [features] default = [] +postgres = ["dep:deadpool-postgres", "dep:tokio-postgres"] [dependencies] aes-gcm = "0.10" async-trait = "0.1" chrono = { version = "0.4", features = ["serde"] } +deadpool-postgres = { version = "0.14", optional = true } hkdf = "0.13" ironclaw_filesystem = { path = "../ironclaw_filesystem" } ironclaw_host_api = { path = "../ironclaw_host_api" } @@ -22,6 +24,7 @@ sha2 = "0.11" subtle = "2" thiserror = "2" tokio = { version = "1", features = ["macros", "rt", "sync"] } +tokio-postgres = { version = "0.7", optional = true, features = ["with-serde_json-1"] } tracing = "0.1" url = "2" uuid = { version = "1", features = ["v4", "serde"] } diff --git a/crates/ironclaw_secrets/src/lib.rs b/crates/ironclaw_secrets/src/lib.rs index 3b69ff7aff4..bad642bbdca 100644 --- a/crates/ironclaw_secrets/src/lib.rs +++ b/crates/ironclaw_secrets/src/lib.rs @@ -11,8 +11,12 @@ mod crypto;

Adding stage timings for + block, resume, and reclaim should expose whether the durable blob path is + paying whole-snapshot CAS cost during blocked gates, without changing the + workload or persistence semantics. +- Expected failure mode: Instrumentation drift could alter the async execution + order or double-count unrelated stages. The change must reuse the existing + `time_stage` helper around only the existing turn-store futures and update + summaries/spans/human output consistently. +- Diagnostic: Patch `ironclaw_stress` attribution, run targeted compile/tests, + then rerun the same Postgres E2E blocked and no-gate turn-state loops so the + reported `turn_store` group includes submit, claim, block, resume, reclaim, + and complete. +- Result: Added `block_run`, `resume_turn`, and `reclaim_run` stage timings to + `ironclaw_stress` and included them in `turn_store` attribution. With + corrected attribution, Postgres pool-size-2 gated `mixed-user-session` + reports `memory-persist-on-block` at 134.9ms operation p95 and 7.15ms + `turn_store` p95, while durable filesystem turn state reports 110.3ms + operation p95 and 49.0ms `turn_store` p95. No-gate `chat-turn` isolates the + blob cost: memory-persist completes 1600/1600 at 15.6ms operation p95 with + `turn_store` p95 about 20us; filesystem completes 1600/1600 at 280.9ms + operation p95 with `turn_store` p95 101.0ms. +- Growth diagnostic: Per-operation spans from the 1600-op filesystem `chat-turn` + run show turn-state p95 climbing by operation-index quartile as the same + per-user `/turns/state.json` grows: 32.7ms, 60.9ms, 78.8ms, then 114.4ms. + The memory-persist control stays flat at 17-24us. This verifies the user's + size-growth concern directly: blob CAS cost grows with snapshot body size. +- Mitigation result: Added stress retention-cap flags and fixed terminal + pruning so old terminal runs also remove their orphaned `TurnRecord`s. + A tiny filesystem hot window (`terminal=4`, `events=24`, `idempotency=8`) + flattens the 1600-op `chat-turn` curve to 17.5ms, 15.7ms, 12.8ms, 13.2ms + turn-store p95 by quartile and cuts operation p95 from 280.9ms to 45.7ms. + The same cap on gated `mixed-user-session` cuts DB growth to +6.0MB and + operation p95 to 94.0ms, but `turn_store` p95 is still 40.5ms. +- Conclusion: Retention caps are a useful guardrail and fix unbounded blob + growth, but they cannot hit the target by themselves. Even the tiny hot + window still pays several filesystem CAS round trips per turn transition. + The durable filesystem turn-state solution needs a typed row/append store + where submit/claim/block/resume/complete mutate small records/log entries + directly instead of rehydrating and rewriting a per-user snapshot. diff --git a/crates/ironclaw_turns/src/memory/mod.rs b/crates/ironclaw_turns/src/memory/mod.rs index 3e0f3377d30..c0bf6e494cd 100644 --- a/crates/ironclaw_turns/src/memory/mod.rs +++ b/crates/ironclaw_turns/src/memory/mod.rs @@ -3052,7 +3052,16 @@ impl Inner { .keys() .any(|reservation| reservation.root_run_id == run_id) { - self.records.remove(&run_id);

Tiny + retention caps flatten the growth but still leave filesystem turn-store p95 + at 16.2ms no-gate and 40.5ms in gated `mixed-user-session`. +- Hypothesis: A filesystem turn-state store that persists typed rows under + `/turns/*` and writes only changed row files can preserve the existing + transition semantics while removing the full-snapshot write-size term. The + first slice should live beside the blob store and be selected explicitly by + stress so we can compare it against the locked E2E flows before changing the + hosted-single-tenant default. +- Expected failure mode: A naive row store that reloads every row on every + transition could trade large blob writes for many small round trips. The + initial success criterion is therefore semantic parity plus a measurable + reduction in DB growth/write-size pressure; if per-transition latency remains + dominated by row rehydration, the next iteration needs a hot in-process row + cache or operation-specific row mutations. +- Diagnostic: Add the row-store implementation with targeted parity tests, + wire an `ironclaw_stress` turn-state backend option for it, then rerun the + same Postgres E2E `chat-turn` and gated `mixed-user-session` loops used in + Cycle 19. +- Result: Added `FilesystemTurnStateRowStore` and `--turn-state-backend + filesystem-row`. The store replays typed append-log deltas from + `/turns/rows/v1/deltas/log`, keeps a hot per-user in-process + `InMemoryTurnStateStore`, and persists targeted deltas for the hot + `submit_turn`, `claim_next_run`, and `complete_run` path. Contract tests + verify it does not write `/turns/state.json`, can reopen from the append log, + and heartbeats do not rewrite durable run rows. +- Row-store iteration signal: The first row-file version reduced DB growth but + was too slow (`chat-turn` 1600/1600 operation p95 790ms, `turn_store` p95 + 346ms, +38.2MB). A generic append-log version with a hot store still paid + whole-snapshot clone/diff cost (`chat-turn` p95 706ms, `turn_store` p95 + 156.8ms). Targeted deltas removed most of that turn-state growth: + Postgres/pool-2 `chat-turn` 1600/1600 now reports operation p95 234.2ms, + `turn_store` p95 48.7ms, and +23.7MB DB growth. The same row backend on + gated `mixed-user-session` 160/160 reports operation p95 187.2ms, + `turn_store` p95 49.7ms, resource governor p95 40.3ms, and +4.3MB DB + growth. +- Controls and remaining gap: The same Postgres full-flow memory turn-state + control reports operation p95 46.7ms and `turn_store` p95 69us, so row + turn-state is much better than blob CAS but still not at the target. At this + point the full `chat-turn` flow is dominated by thread/context writes + (`thread_store_writes` p95 163.2ms, `append_assistant` p95 91.5ms), but row + `submit_turn` still costs 23.0ms p95 and should be optimized further. A + libSQL `filesystem-row` concurrency run aborts with exit code 134; concurrency + 1 succeeds, and libSQL memory succeeds, so the row append path also needs a + libSQL concurrency fix before it can be called portable. +- Conclusion: The solution shape is validated as typed append/row state with + operation-specific deltas, not a blob snapshot and not a generic snapshot + diff. The current slice is a measurable Postgres improvement but not yet + sufficient for hosted-single-tenant parity; next work should make remaining + hot transitions row-native, reduce `submit_turn` to one durable batch/append, + compact or snapshot the append log for restart cost, and address the thread + store blob path that now dominates the full user flow. diff --git a/crates/ironclaw_turns/src/filesystem_store.rs b/crates/ironclaw_turns/src/filesystem_store.rs index 85e394ab0fe..7a75c354a2a 100644 --- a/crates/ironclaw_turns/src/filesystem_store.rs +++ b/crates/ironclaw_turns/src/filesystem_store.rs @@ -69,12 +69,15 @@ use crate::{ mod io;

The current production-shaped turn store is still + `FilesystemTurnStateStore`, which persists a per-user `/turns/state.json` + blob and applies each mutation by reading, overlaying, mutating, and CAS + rewriting the snapshot. +- Hypothesis: Adding a scorer workload that drives submit -> claim -> block -> + resume -> reclaim -> complete plus a separate submit -> claim -> + request_cancel -> cancel flow through `FilesystemTurnStateStore` will make + the blob growth problem visible in the locked latency harness. The workload + should use the same libSQL/Postgres root filesystem comparison and state-hash + parity checks as the rest of the scorer, so future row/append turn-state + changes can be evaluated without ad hoc stress-only commands. +- Expected failure mode: This first harness slice may make Postgres fail the + current dev ratios because it intentionally measures the blob CAS path rather + than the experimental row store. That is acceptable diagnostic pressure; the + fix should then be a production-shaped row/append turn-state path, not a + memory-only shortcut or a benchmark-specific bypass. +- Diagnostic: Add the workload to `harness/latency/runner`, run the runner + focused on that workload for compile/semantic parity, then run `lint.sh` and + the dev scorer to capture p50/p95/p99 and state-hash behavior. +- Result: Added `turn_lifecycle_blob` to the locked latency runner. Each sample + now drives a blocked/resumed run and a cancelled run through + `FilesystemTurnStateStore`, including terminal readback, over the same libSQL + vs Postgres root filesystem comparison used by the other workloads. A first + c4 run exposed a harness bug: the c4 pass reused c1 sample/idempotency keys, + so both backends replayed terminal runs and had nothing to claim.

Full `harness/latency/score.sh --dev` completed and reported the intended hard-fail comparison rows for `turn_lifecycle_blob` c4. + +## Cycle 22 - Postgres Turn-State Row Wiring + +- Baseline: Cycle 21 added the missing local-runtime turn lifecycle workload + and showed the current filesystem blob store hard-fails under concurrent + turn-state pressure. Full `score.sh --dev` reports zero errors and matching + state hashes, but `turn_lifecycle_blob` c4 hard-fails: libSQL p95 5.63s, + Postgres pool-1 p95 15.25s (2.71x), and Postgres pool-2 p95 9.12s (1.62x). + A focused perturbed probe with payload sizes 128/2048 and path depths 2/5 + also passes c1 but fails c3; Postgres pool-2 c3 p95 is 2.82s vs libSQL + 1.87s (1.51x). +- Code signal: Hosted production still constructs `FilesystemTurnStateStore` + directly. The existing `FilesystemTurnStateRowStore` already implements the + turn-state, spawn-tree, event projection, loop checkpoint, and runner + transition traits, but it is only used by tests/stress and is not selectable + through production composition. The host-runtime builder also only exposes a + helper that constructs the blob store. +- Hypothesis: Add a concrete filesystem turn-state wrapper that can hold either + the blob store or the row store, then wire libSQL production to blob and + Postgres production to row. The latency runner should mirror that + production-shaped choice for the turn lifecycle workload: libSQL baseline + stays blob, Postgres treatment uses row. This should remove the per-user + `/turns/state.json` rewrite from hosted-single-tenant Postgres without adding + a benchmark flag, path special case, or in-memory bypass. +- Expected failure mode: The row store currently improves the stress path but + still has gaps: some transitions use generic snapshot deltas, and previous + stress runs showed libSQL row concurrency aborting. This cycle deliberately + leaves libSQL production on blob and may still fail the latency scorer if the + row implementation's generic transitions are too expensive. If so, the next + fix must make `block_run`, `resume_turn`, `request_cancel`, and `cancel_run` + row-native instead of falling back to whole-snapshot deltas. +- Diagnostic: Implement the wrapper and production/harness wiring, run targeted + compile tests, then rerun the focused turn lifecycle scorer and the full dev + score to see whether Postgres c4 exits the hard-fail range. +- Result: Added `FilesystemTurnStateStoreKind`, a concrete wrapper over the + blob and row filesystem stores, and delegated the turn-state, spawn-tree, + event projection, loop checkpoint, and runner transition traits through it. + LibSQL production and the latency baseline stay on the existing blob store; + Postgres production and the latency treatment now use + `FilesystemTurnStateRowStore`. The shared production host-runtime substrate + path also takes the selected layout instead of always constructing a blob + store. The latency workload is renamed from `turn_lifecycle_blob` to + `turn_lifecycle` because it now mirrors the production backend choice. +- Growth signal: `turn_lifecycle` now writes and verifies loop-checkpoint + metadata during the blocked/resumed path; the checkpoint count is derived + from `LATENCY_PAYLOAD_BYTES / 256` and capped at 16, so probe payload + perturbations grow persisted turn-state records instead of only changing + unrelated filesystem payloads. Focused growth score + (`LATENCY_PAYLOAD_BYTES=512,4096`, c1/c4, 12 samples) reports zero errors and + matching hashes: libSQL blob c4 p95 6100.6ms, Postgres row pool-1 c4 p95 + 1416.1ms (0.23x), and Postgres row pool-2 c4 p95 1448.0ms (0.24x). +- Locked score signal: Full `harness/latency/score.sh --dev` reports no + failing comparison rows. The full-score `turn_lifecycle` rows all pass with + matching hashes: libSQL blob c4 p95 8293.6ms, Postgres row pool-1 c4 p95 + 1776.3ms (0.21x), and Postgres row pool-2 c4 p95 1869.6ms (0.23x). The + previous Cycle 21 c4 hard fail is closed without increasing pool size or + changing score semantics. +- `ironclaw_stress` E2E signal: Built `ironclaw_stress` in release mode and + ran the same `mixed-user-session` flow with 8 prefilled threads x 10 turns, + c4, 32 measured operations, blocked/resumed every operation, 2KiB user and + assistant messages, and `context_max_messages=100`. All three runs completed + with 32/32 measured operations and zero failures. LibSQL filesystem blob: + operation p95 60.0ms, throughput 87.0 ops/s, turn_store p95 33.5ms. + Postgres filesystem blob: operation p95 46.7ms, throughput 95.9 ops/s, + turn_store p95 21.6ms. Postgres filesystem-row: operation p95 25.1ms, + throughput 184.4 ops/s, turn_store p95 6.3ms. The stress result validates + the same solution in the full user-turn path, not just the locked latency + micro-workload. +- Validation: Passed `cargo fmt --manifest-path + harness/latency/runner/Cargo.toml`, `cargo fmt -p ironclaw_turns -p + ironclaw_reborn_composition`, `cargo check -p ironclaw_turns`, `cargo check + -p ironclaw_reborn_composition --features libsql,postgres`, `cargo check + --manifest-path harness/latency/runner/Cargo.toml`, + `harness/latency/lint.sh`, focused/full latency scores, `cargo test -p + ironclaw_turns filesystem_turn_state_row_store -- --nocapture`, and the + release `ironclaw_stress` runs above. The existing + `OutboundDeliveryTargetEntry` unused-import warning remains. A broader + `cargo test -p ironclaw_reborn_composition --features libsql,postgres + production_libsql_turn_state -- --nocapture` attempt was not usable: it + pulled in a large transitive debug test graph and failed with `No space left + on device` before reaching a meaningful filtered test result; generated + `target/debug` artifacts were removed afterward to restore disk space. +- Conclusion: For filesystem turn state, the fix is a row/append layout for + Postgres hosted-single-tenant, with libSQL left on the known blob baseline + until the libSQL row concurrency abort from Cycle 20 is fixed. This closes + the scorer-visible blob growth problem for Postgres turn lifecycle and moves + the next latency frontier back to full-flow thread/context/resource costs and + remaining row-native

Full `harness/latency/score.sh + --dev` exits 0 with zero failing comparison rows and + `acceptance_ready=false`; the slowest dev rows are now libSQL blob + `turn_lifecycle`, while Postgres row turn-state is faster and hash-matched. + A broader `probe.sh` was stopped when the requested c32/c100 diagnostic + superseded it. +- High-concurrency signal: `ironclaw_stress mixed-user-session` with + Postgres pool size 2, `filesystem-row` turn state, gated every operation, + 2KiB user/assistant messages, and `context_max_messages=100` completes + c32 320/320 at operation p95 321.6ms, p99 328.4ms, throughput 186.6 ops/s. + c100 500/500 completes at operation p95 660.5ms, p99 719.0ms, throughput + 205.5 ops/s. At c100 the dominant group is `resource_governor` p95 429.3ms + with `resource_reserve` p95 230.2ms and `resource_reconcile` p95 254.5ms; + turn-state row p95 is 109.5ms and thread writes p95 is 106.4ms. +- Baseline caveat: The current libSQL hosted-volume stress baseline using + `memory-persist-on-block` crashes before JSON at c32, even with one measured + operation per worker, and also crashes before JSON at c100. This prevents a + c32/c100 ratio from this stress binary today; the Postgres treatment numbers + are still useful target-side saturation data. +- Hypothesis: The next Postgres full-flow bottleneck is row resource-governor + transaction shape under high concurrency, not turn-state CAS. If reserve and + reconcile serialize more work than necessary, tightening lock scope or + reducing duplicated account-row work should lower c32/c100 p95 without + changing resource accounting semantics. +- Expected failure mode: A resource-governor optimization can easily lose + ancestor budget propagation, reservation close idempotency, or deterministic + lock ordering. Any change must preserve existing resource-governor contract + tests and re-run the c32/c100 stress slice. +- Diagnostic: Inspect `PostgresResourceGovernor` reserve/reconcile paths, + identify whether account locks or transaction boundaries explain the c100 + profile, then patch only if the fix is scoped and covered by tests. +- Boundary result: A scoped batching patch to `PostgresResourceGovernor` was + tested locally (`cargo check -p ironclaw_resources` and `cargo test -p + ironclaw_resources` passed), but it was not kept because it optimizes a + native Postgres domain store that bypasses `RootFilesystem` and is outside + this goal's stated filesystem/composition/CLI surface. The next diagnostic + must keep the filesystem abstraction in the measured path. +- Filesystem-path c32 signal: Running the locked latency runner directly with + `LATENCY_WORKLOADS=turn_lifecycle`, `LATENCY_CONCURRENCY=32`, + `LATENCY_SAMPLES=32`, and `LATENCY_PAYLOAD_BYTES=512` keeps both backends on + the filesystem abstraction. LibSQL blob reported 13/32 errors with + `turn state filesystem CAS retries exhausted`, p95 9014.4ms for successful + samples, and mismatched state hash. Postgres row completed 32/32 with zero + errors: pool-1 p95 3473.6ms and pool-2 p95 3420.4ms. This proves the row + treatment avoids the libSQL blob CAS failure at c32, but the row store still + serializes enough same-user lifecycle work to produce multi-second p95 in + the micro-workload. +- Filesystem-path c100 signal: The same runner at + `LATENCY_CONCURRENCY=100` and `LATENCY_SAMPLES=100` aborted with exit code + 134 before JSON, consistent with the libSQL baseline failing before the + runner can reach Postgres treatment rows.

The `/api/webchat/v2/session` + handler is useful because it crosses bearer auth middleware, descriptor + policy layers, `RebornServicesApi`, and the global auto-approve settings read + without invoking any LLM/provider/network call. +- Hypothesis: Add a `webui_session` workload that builds one cached + `build_reborn_runtime -> build_webui_services -> webui_v2_app` stack per + backend, then measures authenticated `GET /api/webchat/v2/session` requests + through Axum `oneshot`. This should close a Stage 0 WebUI gap while staying + inside composition/runtime abstractions. It must not reach into Postgres + tables, thread stores, or filesystem paths directly. +- Workload shape: The session route has a real read rate limit of 120 requests + per caller per minute, so the harness should use deterministic multi-user + session bootstrap tokens instead of measuring a guaranteed 429 after the + first 120 samples for one caller. The sample-to-user mapping must be identical + for libSQL and Postgres so visible response hashes remain comparable. +- Expected failure mode: Building this through a stub service facade would hide + runtime/store latency, while building it with ad hoc DB handles would bypass + the abstraction the user explicitly asked about. The workload should use + `local_runtime_build_input` for hosted-volume libSQL and hosted + single-tenant Postgres build input for Postgres, with the same production- + relevant Postgres pool caps as the rest of the harness. +- Diagnostic: Patch the harness only, run formatting/check/lint, then run a + tiny `webui_session` smoke for both backends before any larger score. +- Result: Added `webui_session` to the locked runner and documented it in the + harness README. The workload builds one cached hosted-volume libSQL runtime + and one cached hosted-single-tenant Postgres runtime per pool size through + `build_reborn_runtime`, `build_webui_services`, and `webui_v2_app`; measured + samples are Axum `oneshot` requests to `/api/webchat/v2/session`. Added a + non-env `RebornBuildInput::hosted_single_tenant_postgres` constructor so the + harness can pass the already-capped Postgres pool into composition instead of + reopening storage through process env. +- Validation: `cargo fmt --manifest-path harness/latency/runner/Cargo.toml + --check`, `cargo fmt -p ironclaw_reborn_composition --check`, + `cargo check --manifest-path harness/latency/runner/Cargo.toml`, + `cargo check -p ironclaw_reborn_composition --features + webui-v2-beta,libsql,postgres`, `harness/latency/lint.sh`, and + `git diff --check` passed. The first smoke run hit `No space left on device` + while writing debug archives; removing only the generated + `harness/latency/runner/target/debug/incremental` cache freed space, and the + rerun passed. +- Tiny smoke: With `LATENCY_WORKLOADS=webui_session`, + `LATENCY_WARMUP=1`, `LATENCY_SAMPLES=4`, and `LATENCY_CONCURRENCY=1`, both + backends completed with zero errors and matching state hash + `88db09960433a88e`. libSQL p95 was 1.92ms; Postgres pool-1 p95 was 0.62ms; + Postgres pool-2 p95 was 0.51ms. +- Dev score: `harness/latency/score.sh --dev` completed with all c1/c4 + comparisons passing and zero errors.

This isolates the governor as a real + production-shaped bottleneck, not a side effect of turn/thread stores. +- Hypothesis: `PostgresResourceGovernor` always ensures, locks, and rewrites + every account row in the resource-scope cascade. With one hosted tenant, + every reservation/reconcile serializes on the same tenant account row even + when there are no finite limits installed. We need a row-store shape that + keeps durable reservation lifecycle and finite-limit enforcement, but avoids + hot shared aggregate-row writes for unlimited accounts. A safe first step is + to move no-finite-limit reservations onto append/row lifecycle writes while + leaving finite-limit accounts on the existing locked aggregate path. +- Expected failure mode: Skipping aggregate writes blindly would break + `usage_for`, `reserved_for`, `account_snapshot`, and future finite-limit + installation after no-limit activity. The patch must either reconstruct + unlimited account snapshots from durable reservation rows or merge prior + reservation rows when a finite limit is installed. It must not return success + before a durable reservation lifecycle write is committed. +- Result: `PostgresResourceGovernor` now keeps the finite-limit path on the + existing locked account aggregates, but moves unlimited accounts to durable + reservation lifecycle rows instead of rewriting hot shared account rows for + every reserve/reconcile/release. The reservation table now stores indexed + `account_keys` so `account_snapshot` and later finite-limit installation can + rebuild reserved/spent tallies from reservation rows without scanning every + reservation. `set_limit` takes an exclusive account advisory lock and + lifecycle operations take shared account advisory locks so a finite limit + cannot be installed concurrently with an unlimited-path reservation update. +- Abstraction boundary: This cycle does not bypass the turn-state filesystem + abstraction. The optimization is in the native hosted-single-tenant + Postgres resource governor path, which was already separate from the + filesystem-backed resource governor. It still waits for the durable + reservation row write to commit before returning success; it only skips + aggregate account-row writes when no finite limit exists. +- Correctness fix during review: reservation creation now uses an atomic + insert-and-conflict check instead of the lifecycle update upsert, so + concurrent callers cannot both succeed with the same reservation id on the + shared-lock unlimited path. This post-measurement fix was covered by + compile/tests; I did not rerun full c32/c100 stress after it because the + workspace had less than 800MiB free and the hot-path shape is unchanged. +- Resource-only treatment: `ironclaw_stress --scenario reserve-reconcile` at + c100/pool-2 completed 400/400 with operation p95 158.9ms and throughput + 859.5 ops/sec, down from the c100 baseline p95 198.0ms and throughput + 496.8 ops/sec. +- Full-flow stress signal: `ironclaw_stress` mixed user-session with Postgres + row turn state and pool size 2 completed with zero errors after the indexed + reservation-key patch. c32 completed 128/128 with operation p95 154.4ms, + turn-store p95 40.6ms, and resource-governor p95 52.2ms. c100 completed + 200/200 with operation p95 388.1ms, turn-store p95 71.8ms, and + resource-governor p95 213.3ms.

Replay remains + unchanged because the flusher uses `filesystem.append_batch` with one + serialized delta per record. +- Result: Kept the yield-only group-commit flusher. `FilesystemTurnStateRowStore` + now enqueues each non-empty `SnapshotDelta` with a per-delta ack, a single + flusher drains queued deltas into one `ScopedFilesystem::append_batch` call + per flush, and both generic and targeted apply paths release the snapshot + mutex before awaiting durable persistence. Empty deltas still short-circuit, + single-delta flushes use `append`, and journal replay remains compatible + with existing single-delta records. +- High-concurrency turn-state diagnostic: Postgres-only `turn_lifecycle` with + payload 2048, 64 samples, and pool size 2 completed with zero errors and + stable state hash `660086a8484d5400`. c32 p95 improved from the cycle-36 + 2314ms baseline to 2142ms, with p50 1773ms, p99 2230ms, and throughput + 19.96 ops/sec. c100 p95 improved from 8666ms to 3519ms, with p50 3445ms, + p99 3520ms, and throughput 18.18 ops/sec. +- Full-flow stress signal: `ironclaw_stress` mixed-user-session with Postgres + row turn state, pool size 2, c100, users 100, model/tool latency 0, and + 200 total operations completed 200/200 with operation p95 400.6ms, + throughput 339.7 ops/sec, turn-store p95 70.6ms, and resource-governor p95 + 237.4ms. A longer sustained c100 run with 20,000 total operations also + completed 20,000/20,000; operation p95 was 722.1ms, throughput 217.2 ops/sec, + turn-store p95 22.0ms, and resource-governor p95 607.2ms, keeping the + governor as the top full-flow bottleneck. +- Dev score and validation: `harness/latency/score.sh --dev` passed 54 results + and 36 comparisons with zero failures. Dev-shaped c4 `turn_lifecycle` stayed + well ahead of libSQL: libSQL p95 8415ms, Postgres pool-1 p95 447ms, and + Postgres pool-2 p95 423ms. Additional checks passed: + `harness/latency/lint.sh`, `cargo check -p ironclaw_turns`, `cargo test -p + ironclaw_turns --test filesystem_turn_state_contract + filesystem_turn_state_row_store_persists_rows_without_state_blob`, and + `cargo test -p ironclaw_turns --test loop_checkpoint_store_contract + filesystem_turn_state_row_store_loop_checkpoint_roundtrip_and_snapshot`. +- Next lever: shard the in-memory turn state per run. Use per-run locks for + targeted transitions, keep the global lock only for `claim_next_run`'s + cross-run view, and keep journal ordering in the single flusher. While doing + that, audit `build_delta`/`apply_delta` for O(snapshot) vector scans or + rebuilds per write and consider row-keyed maps for run storage. diff --git a/crates/ironclaw_turns/src/filesystem_store.rs b/crates/ironclaw_turns/src/filesystem_store.rs index 3008ea43fb7..3ed48bfe217 100644 --- a/crates/ironclaw_turns/src/filesystem_store.rs +++ b/crates/ironclaw_turns/src/filesystem_store.rs @@ -648,7 +648,10 @@ where Self::Blob(FilesystemTurnStateStore::new(filesystem)) } - pub fn row(filesystem: Arc>) -> Self { + pub fn row(filesystem: Arc>) -> Self + where + F: 'static, + { Self::Row(FilesystemTurnStateRowStore::new(filesystem)) } diff --git a/crates/ironclaw_turns/src/filesystem_store/row_store.rs b/crates/ironclaw_turns/src/filesystem_store/row_store.rs index eb286b212ad..cdca9c01655 100644 --- a/crates/ironclaw_turns/src/filesystem_store/row_store.rs +++ b/crates/ironclaw_turns/src/filesystem_store/row_store.rs @@ -12,7 +12,7 @@ use ironclaw_filesystem::{ };

The `postgres` Cargo feature remains as a + compatibility feature but no longer exposes direct resource-governor SQL. +- Runtime shape: hot reserve/reconcile/release updates per-account-sharded + in-memory tallies plus a reservation map, then enqueues one + `ResourceGovernorDelta`.

It deliberately does not snapshot + the hot in-memory authority because memory can include deltas that have not + yet received durable journal sequence numbers. +- Correctness fix during validation: the first focused c100 reserve/reconcile + control stopped at 822/1000 after synchronous compaction entered the hot + path. Moving compaction to the durable background replay path fixed the hang + and kept reserve/reconcile durability gated only on the delta journal ack. +- Full-flow gate: `ironclaw_stress` mixed-user-session with Postgres + filesystem-row turn state, pool size 2, c100, users 100, and zero synthetic + model/tool latency completed 200/200 with zero failures. Final operation p95 + was 291.2ms, throughput 482.5 ops/sec, turn-store p95 124.7ms, and + resource-governor p95 31.1ms. The old c100 governor p95 was 271.0ms, so the + governor is no longer the top attributed group; thread-store writes are now + top at p95 125.7ms. +- Resource-only control: Postgres reserve-reconcile c100/pool-2 completed + 1000/1000 with zero failures after the compaction fix, operation p95 41.9ms, + and throughput 5584.5 ops/sec.

Production now uses `FilesystemResourceGovernor`: process-local, per-account-sharded quota authority backed by the shared `RootFilesystem` append log. Quotas are process-global in the hosted runtime, so the in-process authority owns admission decisions; successful mutations are durably acknowledged after their delta is flushed through the filesystem group-commit journal. `FilesystemResourceGovernorStore` remains as the CAS snapshot compaction store at `/resources/snapshot.json`; restart recovery loads that snapshot and replays `/resources/deltas/log` from the recorded cursor. Persistent implementations add a storage failure mode to every governor operation that touches durable state, including `set_limit`. Lock, read, write, serialization, deserialization, or snapshot schema validation failures return `ResourceError::Storage` and must fail closed: callers must not start costed or quota-limited work when storage state cannot be trusted. Durable snapshots are versioned with `schema_version`; unknown top-level fields, partial snapshots, malformed JSON, and unsupported future schema versions are rejected instead of being silently ignored. diff --git a/harness/latency/runner/Cargo.lock b/harness/latency/runner/Cargo.lock index 34366f00476..1a3980d5777 100644 --- a/harness/latency/runner/Cargo.lock +++ b/harness/latency/runner/Cargo.lock @@ -3307,17 +3307,14 @@ version = "0.1.0" dependencies = [ "chrono", "chrono-tz", - "deadpool-postgres", "fs2", "ironclaw_filesystem", "ironclaw_host_api", - "libsql", "rust_decimal", "serde", "serde_json", "thiserror 2.0.18", "tokio", - "tokio-postgres", "tracing", "uuid", "windows-sys 0.61.2", diff --git a/harness/latency/runner/src/main.rs b/harness/latency/runner/src/main.rs index fae2d44d9e7..0f63260c250 100644 --- a/harness/latency/runner/src/main.rs +++ b/harness/latency/runner/src/main.rs @@ -31,8 +31,7 @@ use ironclaw_reborn_composition::{ };

The probe still hard-fails only where the libSQL side + changes state hash under c8 pressure: `control_plane_snapshot` c8 has one + libSQL secret-store filesystem error, and `turn_lifecycle` c8 has two libSQL + `turn state filesystem CAS retries exhausted` errors. Postgres remains + error-free in those rows and materially faster, so the probe is useful as a + baseline-health warning rather than a Postgres latency regression. +- Current Postgres bottleneck from the full mixed-flow gate after Cycle 40: + c100/pool-2 operation p95 is 291.2ms; resource-governor p95 is down to + 31.1ms, while `thread_store_writes` p95 is 125.7ms and `turn_store` p95 is + 124.7ms. The next Postgres latency lever should target the filesystem-backed + thread/turn write path, not the governor. +- Hypothesis: mixed-user-session still pays too many independent durable + filesystem writes during turn admission and assistant append/finalization. + The governor fix proved RootFilesystem group-commit can remove a hot + Postgres-attributed span without bypassing persistence. Inspect the thread + store and turn-store write path for serial per-message/metadata writes that + can be collapsed into existing batch primitives (`put_many`, `append_batch`, + or transaction-shaped helpers) while keeping identical visible responses, + event counts, and state hashes. +- Expected failure mode: batching thread writes incorrectly could change + message ordering, record-kind metadata, search/query visibility, or state + hashes. The change must stay behind the real RootFilesystem abstraction, + preserve durable acks, and avoid any benchmark-path or payload-size special + case. If the thread-store path already uses the available batch primitive, + switch approach to the turn-store append/claim/submit path rather than + tuning the same knob. + +## Cycle 42 - LibSQL Turn-State Cliff Diagnostic + +- Supersedes the Cycle 41 implementation direction. The next gate is the + libSQL `turn_lifecycle` cliff on the identical RootFilesystem-backed row + store: libSQL c4 p95 is about 7.8s while Postgres c4 is about 35ms. A + 200x gap is treated as one pathological cause, not general slowness. +- Graph note: `codebase-memory-mcp` remains unavailable (`Transport closed`), + so this cycle uses crate guardrails and targeted source reads. +- Pre-instrumentation observations: `LibSqlRootFilesystem` already migrates to + `PRAGMA journal_mode = WAL` and applies `synchronous = NORMAL` per + connection, so fsync-per-append is not assumed to be dominant. The backend + does create a fresh libSQL connection for every RootFilesystem operation and + applies the PRAGMA batch on each connect. The turn-state row store already + uses the delta-journal flusher and `append_batch` for grouped deltas, with + single-delta flushes falling back to `append`. +- Diagnostic plan before any fix: add opt-in libSQL RootFilesystem timing that + emits per-phase timings for `connect`/PRAGMA setup, write lock/transaction + begin, SQL execution, row iteration, and commit for `append`, + `append_batch`, `put`, `get`, `tail`, and `reserve_sequence`. Attribute the + c4 `turn_lifecycle` time across the requested suspects: journal/synchronous + mode, connection-per-op cost, append shape, unprepared statement execution, + and write-lock serialization. Record the dominant cause with measured + numbers here before applying a fix. +- Diagnostic run: `LATENCY_WORKLOADS=turn_lifecycle`, c4, 5 warmups, 40 + measured samples, libSQL + Postgres pool-2. Output captured under + `target/latency-diagnostics/cycle42-c4.*` with + `IRONCLAW_LIBSQL_FS_DIAG=1`. +- Measured result before fix: libSQL p50 2029.9ms, p95 4691.5ms, p99 + 5329.8ms, throughput 1.82 ops/sec; Postgres pool-2 p50 27.2ms, p95 + 37.7ms, p99 44.1ms, throughput 138.0 ops/sec. State hashes matched + (`7fc054292d2f85f0`) and errors were zero. +- Dominant cause: the libSQL `turn_lifecycle` path is not actually using the + row store in the latency runner. `harness/latency/runner` constructs + libSQL with `FilesystemTurnStateStoreKind::blob(scoped)` while Postgres uses + `FilesystemTurnStateStoreKind::row(scoped)`. The diagnostic log confirms all + turn-state filesystem traffic for libSQL is `/turns/state.json` blob + `get`/`put`, with no turn-state `append`/`append_batch` traffic. +- Blob-store numbers: one run produced 1,753 turn-state `get`s and 1,348 + versioned `put` attempts against the single `/turns/state.json` blob. The + snapshot body was p50 732,946 bytes, p95 1,234,918 bytes, max 1,293,813 + bytes. Only 540 of 1,348 versioned updates succeeded; 808 returned zero + rows and paid a `current_version` lookup, so 60.0% of write attempts were CAS + retries over the growing full snapshot. +- Suspect attribution: WAL/synchronous is already `journal_mode=WAL` plus + `synchronous=NORMAL`, and append is not on the hot path in this libSQL run. + Fresh connections/PRAGMAs are measurable but secondary: 6,607 opens totaled + 527ms and 6,606 PRAGMA batches totaled 3,764ms (PRAGMA p95 1.76ms). The + dominant cost is full-blob read/modify/write amplified by CAS conflicts and + SQLite's single-writer serialization: `put` preflight totaled 2,928ms, + `put` execute totaled 3,383ms, successful `put` total p95 was 10.0ms, and + each losing CAS attempt still rewrote the same large logical state path. +- Fix direction after measurement: stop using the blob turn-state layout for + libSQL in the latency/hosted-single-tenant path; move libSQL to the existing + RootFilesystem row store so it uses grouped delta `append_batch` like + Postgres. Keep libSQL backend PRAGMA/config changes out of the first fix + because the measured cliff is not fsync mode or statement parse in the row + append path. +- Fix applied: production libSQL hosted-single-tenant wiring and the latency + runner now use `FilesystemTurnStateStoreKind::row` for turn state. The + temporary libSQL RootFilesystem diagnostic hooks were removed after this + attribution so the final hot path does not retain benchmark instrumentation + overhead. +- Post-fix diagnostic run with the same c4 focused profile and temporary + filesystem timing confirmed the path changed from `/turns/state.json` + `get`/`put` traffic to row-store delta journal traffic: + `/turns/rows/v1/deltas/log` saw 580 `append` and 545 `append_batch` phase + records, while the meta snapshot path saw only four `get`s and four `tail`s. + libSQL c4 p95 fell to 30.0ms, Postgres pool-2 c4 p95 was 31.2ms, errors were + zero, and state hashes matched (`7fc054292d2f85f0`). +- Clean launch-ref-shaped baseline rerun without diagnostics: + `LATENCY_WORKLOADS=turn_lifecycle`, c4, 5 warmups, 40 measured samples, + libSQL + Postgres pool-2. libSQL p50/p95/p99 was 27.7/30.9/32.2ms with + throughput 143.9 ops/sec; Postgres p50/p95/p99 was 23.4/27.6/28.8ms with + throughput 168.2 ops/sec. Errors were zero and state hashes matched. This + clears the requested libSQL c4 gate (target <=100ms, within about 2x of + Postgres); libSQL is 1.12x Postgres p95 in this clean focused run. +- Acceptance note: this run is recorded as the libSQL turn-lifecycle baseline + evidence for the acceptance-ready path, but the runner still reports + `acceptance_ready=false` because the full harness flag is currently hard-coded + and still represents missing request-level trigger/approval/resource gates, + not this focused turn-state baseline. +- Full dev scorer after the fix: `harness/latency/score.sh --dev` produced 54 + result rows and 36 comparison rows. The turn-lifecycle c4 rows passed for + both Postgres pool sizes with zero errors and matching hashes; libSQL c4 p95 + was 39.8ms, Postgres pool-1 c4 p95 was 31.4ms, and Postgres pool-2 c4 p95 + was 34.0ms. The run had two c1 p99-only hard-fail rows (`put_get` pool-1 and + `turn_lifecycle` pool-2) despite faster Postgres p50/p95 and matching state + hashes. +- Small-sample outlier check: reran the two affected workloads at c1 with 30 + warmups and 300 measured samples. All four comparisons passed with zero + failures and matching hashes. `put_get` Postgres p99 ratios were 0.29 + (pool-1) and 0.13 (pool-2); `turn_lifecycle` Postgres p99 ratios were 0.52 + (pool-1) and 0.92 (pool-2). +- Postgres c100 mixed-flow regression gate: `ironclaw_stress` with + mixed-user-session, filesystem-row turn state, pool size 2, concurrency 100, + users 100, and zero synthetic model/tool latency completed 200/200 with zero + failures. Operation p95 was 245.8ms, throughput was 517.4 ops/sec, + turn-store p95 was 81.4ms, resource-governor p95 was 15.8ms, and + thread-store writes remain the top group at p95 148.3ms. This does not + regress the prior c100 gate (291.2ms op p95, 482.5 ops/sec). +- Validation: `cargo fmt -p ironclaw_reborn_composition --check`, + `cargo check -p ironclaw_reborn_composition --features libsql,postgres`, + `cargo check --manifest-path harness/latency/runner/Cargo.toml`, + `cargo test -p ironclaw_turns --test filesystem_turn_state_contract`, + `cargo test -p ironclaw_filesystem --features libsql,postgres --test + db_root_filesystem_contract`, `cargo test -p ironclaw_reborn_composition + --features libsql,postgres --test libsql_substrate --test + postgres_substrate`, the focused c4 clean latency run, the focused c1 + outlier rerun, the full dev scorer, and the c100 mixed-flow stress gate were + run.
