At insert: + `lamport = 1 + max(local_clock, max(lamport over every event imported for + this database so far))`. The reference `_ConceptRepository._allocate()` + today computes `logical_time = max(local max over + context_concept_events.logical_time, context_concept_clock.logical_time) + + 1` — correct for a single, non-replicating database. B3's replication + apply path must extend this: **importing any foreign event with lamport + `L` first advances `context_concept_clock.logical_time` to at least `L`** + (a clock-tick observation with no accompanying local event), so that the + next *local* insert's `1 + max(...)` term already accounts for every + lamport value this database has ever seen, imported or local. This is the + standard Lamport-clock rule; it is the one behavioural change this design + requires beyond what `_allocate()` already does, and it is a required + assertion in the two-copy matrix (below, item 4). +- **`machine_id`** is `context_access_state.instance` — the stable, + UUID-hex, per-database replica identity created once at first use + (`context/response_schema.py:31`) and already read by + `replication/policy.py`, `replication/retention.py`, + `replication/reconcile.py`, and stored per-peer in + `context_replica_peers.local_instance` + (`replication/ledger_schema.py`). This is the same identifier BL-1's + planned `machine_id` + per-machine `seq` sync tiebreak + (`reviews/sessionweaver-plans/BACKLOG-phase-2.md`) must resolve to when + B5 implements it — B3 does not mint a second replica identity, and BL-1's + fix must reuse this one rather than add a third. The sidecar's existing + `context_concept_events.origin_instance` column *is* this value, recorded + once per event at insert time; B3 does not rename the column, it + specifies what it must contain. +- **`event_id`** is `context_concept_events.id` — A3a's immutable 64-char + identity, a deterministic hash of the event's own payload (concept id, + parent event id, standing, actor, reason, display timestamp, + `origin_instance`, `origin_seq`, `logical_time`). It is the final, + content-derived tiebreaker: two events can only collide on it if every + other field — including `machine_id` and `lamport` — is identical, which + the schema's `UNIQUE(id, concept_id)` and `UNIQUE(origin_instance, + origin_seq)` constraints already make a genuine duplicate rather than a + real conflict. +- **Duplicate `machine_id` is diagnosed and refused, never merged.** If + replication ever observes two live peers reporting the same + `context_access_state.instance` (a cloned database presented as a second + replica, not a legitimate additional one), that is an identity + violation, not an ordering case: the reconcile step raises a structured, + named error and refuses the exchange rather than interleaving the two + peers' `origin_seq` sequences as if they were one honest replica. +- **Rows are append-only.** `context_concept_events` already forbids + `UPDATE` (`context_concept_events_immutable` trigger) and this design + adds no delete path; replication only ever inserts events it does not + already have (by `id`), never rewrites one. +- **No wall-clock timestamp participates in ordering.** `display_timestamp` + is retained purely as a human-readable label; the standing order is a + pure function of `(lamport, machine_id, event_id)`, consistent with + `EXECUTION-ERRATA.md` decision #5 ("timestamp-only latest-state + resolution is forbidden"). + +**How the per-database clock maps onto this order:** `context_concept_clock` +is not itself part of the standing-order key — it is the *local allocator's* +state, one row per database, advanced under every insert (local or +clock-tick) and never read cross-database. The order above is computed +purely from `context_concept_events` rows already present after a sync +exchange; the clock only has to guarantee that the *next* local event this +database creates gets a `lamport` no replica has already used for a +causally-prior event. + +### Two-copy test matrix (normative) + +B3 must pass every scenario below before its acceptance line is satisfied +(ruling R2); each is a required test, not an illustrative example: + +1. **Opposite replication orders converge identically** — running A→B then + B→A produces the same final event set on both copies as running B→A + then A→B does (starting from the same two pre-sync states each time). + Both orders yield identical event sets, identical ordered digests + (canonical serialization of the event set, hashed), and identical + computed standing for every concept. +2. _(covered by 1 — the two orders are the two runs of the same + assertion.)_ +3. **Replay is idempotent** — re-running either sync direction a second + time, with nothing new to exchange, adds zero new rows on either copy. +4. **A causally-later local event outranks prior concurrent ones** — after + two replicas have converged, a new event created on either copy + receives a `lamport` strictly greater than both of the concurrent events + that caused convergence, and that new event is the current standing on + *both* copies once they resync. +5. **Read-model rebuild is hash-equivalent** — deterministically + recomputing each concept's current standing from its full event history + (not from any cached "current" pointer) produces an identical digest on + copy A and copy B. +6. **Accept-on-A / retire-on-B (concurrent) resolves to the computed + winner** — the test independently computes the expected winning event + from the `(lamport, machine_id, event_id)` triple of the two concurrent + events (not from which side "should" win by narrative), then asserts + that both copies show that exact computed standing after sync — in + either sync direction. +7. **Accept then retire (causal) resolves to `retired` on both** — accept + on one copy, sync, retire (chained from the synced accept event) on the + other, sync again: both copies show `retired`, because the retire + event's `parent_event_id` chains from the already-synced accept event, + giving it a strictly later causal position by construction, not by + ordering luck. + +### Refresh-failure seam for B2 + +A named, monkeypatchable hook is called from +`agent_session_tools.export_sessions._run_export`, after the per-source +export loop's `conn.commit()` that persists captured sessions and before +the function returns. The hook triggers an *incremental* ontology rebuild +scoped to the sessions this run touched. Its contract: + +- **The hook is a single, separately-named call** (not inlined into the + export loop), so a test can monkeypatch it to raise without touching any + export/exporter code. +- **A hook failure never rolls back the capture.** The already-committed + session and message rows from this run remain committed and unchanged — + there is no shared transaction between session capture and the ontology + refresh, and the hook call is wrapped so any exception it raises is + caught, not propagated, consistent with `EXECUTION-ERRATA.md` decision + #7 ("session capture is authoritative"). +- **The failure is surfaced as a structured warning on a named + channel/field** — not merely printed — so `session-maint`, `doctor`, and + a caplog-based test can all observe it the same way: a log record from a + stable, named logger/field pair (e.g. an `ontology_refresh_failed` event + field), not a free-text string a future refactor could silently reword + out of existence. +- **`session-maint ontology-rebuild` recovers.** Running the existing + maintenance sweep after a refresh failure brings the ontology back to a + healthy, fully-covered state — the failure is a staleness window, never + a permanent gap, matching Q1(a)'s "idempotent `session-maint` sweep for + missed rows." + +Required tests assert all three facts together on one fault injection: the +captured session rows are present and unchanged; the structured warning +fired on the named channel/field; and a follow-up `session-maint +ontology-rebuild` call converges the ontology to the same state a +failure-free run would have reached. + +### Seed sanitization + +`agent_session_tools.sync._seed_remote_db` already takes a SQLite Online +Backup of the local database into a temporary snapshot file before `scp` +seeds a never-before-synced remote +(`packages/agent-session-tools/src/agent_session_tools/sync.py:456`). This +design adds one step to that snapshot, before the `scp`: **every row of the +six v48 ontology tables, and the `ontology_build_state` singleton, is +stripped from the snapshot.** The remote is seeded with every table's +schema present (so it opens without error) but zero ontology rows. +Immediately after a successful seed, the destination is expected to run its +own local ontology rebuild (the same incremental/full rebuild B2 wires into +`_run_export`, or an explicit `session-maint ontology-rebuild`) before it is +considered ready — the remote's tier-1 ontology is *derived on the remote*, +never inherited from the source's snapshot. This is a direct consequence of +Q1(a) (never synced) applied to the one code path that currently moves a +whole-database snapshot between machines: an unsanitized seed would make +the remote's first-ever ontology state a *copy*, not a *derivation*, which +is exactly the property Q1(a) forbids. + +### Recall contract (frozen for B4) + +B4 implements `memory_recall` in `agent_session_tools.mcp_server` against +the shape A4 measures its retrieval benchmark against; B4's acceptance +condition is that this tool's hit lists are identical, not merely similar, +to A4's library call (`recall(db, question, ...)`) on the same backup and +visibility (ruling R6 — "same planner + same DB must be deterministic; +'noise' launders defects").

The plan (`COMPLETION-PLAN.md` §3, B1) +names eight call sites under the heading "the seven `request_scope()` +sites" — this design carries the list forward exactly as named, flagging +the count mismatch rather than silently resolving it, since correctness of +the list matters more than the label: + +1. `packages/studyloop/src/studyloop/parking.py:40-58` (`_connect()`'s + board-seeding read) +2. `mcp/tools.py::log_struggle` +3. `mcp/tools.py::get_study_backlog` +4. `mcp/tools.py::get_active_topics` +5. `mcp/tools.py::get_next_action` +6. `mcp/tools.py::record_topic_progress` +7. `mcp/tools.py::get_concept_context` +8. `mcp/tools.py::get_study_history` + +Each of the above, plus every tool registered by +`agent_session_tools.mcp_server` (`session-db-mcp`) and by +`studyloop.mcp.server` (`studyloop-mcp`), returns one structured diagnostic +shape on a missing/invalid scope — a stable error code plus a one-line, +actionable message (e.g. "run `studyloop config init` to classify this +project") — never a bare traceback. `agent_session_tools.context.public +.open_context()`'s existing "never silently migrate an agent request" +posture is the model this diagnostic follows: fail closed, explain why, +name the fix. `session-db-mcp`'s `open_context()` on a database that does +not exist yet returns this same diagnostic shape, not a distinct +file-not-found error. + +### Compatibility seams + +- **`ConceptService`'s public surface is frozen before B4 depends on it** + (`EXECUTION-ERRATA.md` correction #5: "freeze the B3 service interface + before B4 edits MCP registration/retrieval").

This design does not restate R8's stage + ordering (A7 → B-OS → … → R-SL → B6 → R-SW, `COMPLETION-PLAN.md` §3) — it + names the one gate all of those stages check the same way, so a + compatibility regression caught at B6 cannot be blamed on "that's A7's + gate, not mine." + +## Risks / Trade-offs + +- **The Lamport-advance-on-import step is new behaviour, not present in + the reference `_allocate()`.** Without it, a database that only ever + imports events and never creates its own could keep allocating + `lamport` values below imported ones, silently reintroducing + timestamp-shaped bugs through the back door. Mitigated by making the + advance-on-import assertion an explicit, required item in the two-copy + matrix (item 4) rather than trusting code review alone to catch its + absence. +- **`context_access_state.instance` was designed for the existing context + replication protocol, not for concept-event ordering.** Reusing it + avoids a second identity primitive, but ties the concept sidecar's + correctness to that identity never being cloned or reset independently + of the database it names. The "duplicate `machine_id` is diagnosed, + never merged" rule exists specifically to fail loudly rather than + silently interleave two histories if that assumption is ever violated + (e.g. a database file copied instead of replicated). +- **Ontology seed-sanitization adds a second post-processing step to an + already-fragile cross-host path** (`_seed_remote_db` shells out to `ssh` + and `scp`).

The exporter data-loss +class this retrofit's benchmark corpus depends on was already fixed and +committed (`7f9a19ec`, "preserve history and contain batch failures"), and +this change's design freezes the corpus-integrity precondition that +benchmark accordingly. + +This proposal creates the OpenSpec change that freezes those decisions as +spec and design *before* any Phase B implementation task opens a worktree, +per `EXECUTION-ERRATA.md` execution-order correction #3 ("Create the +StudyLoop OpenSpec change before B1 code") and council ruling R2's +acceptance condition for this stage ("not `spec-check` alone" — an +independent design review must approve the standing order and its test +matrix). Owner decisions O1–O7 in `COMPLETION-PLAN.md` §6 govern how the six +downstream tasks (B1–B6) execute against this design: O3 places the +rescue-branch backlog ports (BL-1..BL-4) inside B5 rather than as a separate +stage; O6 records that the production exporter is presently a pre-fix pin, +so this design's migration and refresh-failure guarantees must hold +regardless of which exporter build is live; O7 confirms the standing +push-after-every-commit authority the downstream tasks rely on. This change +does not itself execute O1, O2, O4 or O5 (SessionWeaver release cadence, the +dead `v0.1.0` release link, the undone StudyLoop `0.3.0` tag, and the +`.gitignore` commit) — those are Stage 0/A7/R-SL housekeeping outside this +capability set. + +## What Changes + +- Freeze the **cross-machine standing order** for replicated concept + lifecycle events (`lamport`/`machine_id`/`event_id` triple, append-only, + duplicate-`machine_id` refused) and the **two-copy test matrix** it must + pass, so B3 implements a specified algorithm instead of inventing one. +- Freeze two **additive, rollback-documented migrations**: v48 (tier-1 + ontology tables, derived and rebuildable, never present in either sync + table list) and v49 (the concept sidecar: assertions-linked concepts, + append-only lifecycle events, the per-database logical clock, and FTS). +- Freeze the **refresh-failure seam**: an incremental ontology rebuild + invoked from `export_sessions._run_export` must never roll back a + committed session capture; failure is a structured, non-fatal warning + recoverable by `session-maint ontology-rebuild`. +- Freeze **seed sanitization**: seeding a fresh remote database strips + ontology and ontology-build-state rows from the seed snapshot and triggers + a destination-local rebuild, so derived data is never shipped as if it + were replicated fact. +- Freeze the **fresh-install scope contract**: generated configuration + writes `memory.default_scope: unclassified` while the runtime default + stays unset; every one of the eight currently-unguarded + `request_scope()` call sites (the source plan mislabels the list "seven") and both MCP servers return one structured + diagnostic instead of an unhandled `ScopeError`/traceback. +- Freeze the **`memory_recall` contract** (concept-then-session shape, + citations, provenance, AND→OR planner semantics) that B4 must implement + byte-for-byte and that B4's acceptance requires be identical, hit-for-hit, + to the already-measured library call on the same corpus and visibility. +- Freeze the **compatibility seams**: the `ConceptService` public surface is + fixed before B4 depends on it, and a named cross-stage package/API + compatibility gate spans A7, B6 and the two release stages. +- Add delta requirements to six existing capabilities + (`harness-session-memory`, `data-store-and-sync`, `mcp-server`, + `session-export`, `health-and-diagnostics`, `configuration-and-secrets`) + describing this target behaviour; no capability is newly created. +- **Preserved, not changed by this or any downstream Phase B task**: no + embeddings of any kind ship (concept or session); `proposed_state` on + `context_assertions` remains execution state — concept kind and lifecycle + standing live only in the sidecar; the tier-1 ontology is never added to + `SYNC_TABLES` or `GLOBAL_SYNC_TABLES`; the original 25-question gold + benchmark set is never edited. + +## Capabilities + +### New Capabilities +_(none — every capability touched by this change already exists under +`openspec/specs/`)_ + +### Modified Capabilities +- `harness-session-memory`: adds the recall surface, code-enforced wind-down, + and concept lifecycle guarantees learners and harnesses can rely on when + retrieving or recording session memory. +- `data-store-and-sync`: adds the v48/v49 migrations, the ontology's + permanent absence from both sync-table lists, and the frozen cross-machine + standing order plus two-copy test matrix for replicated concept events. +- `mcp-server`: adds the `memory_recall` and `memory_winddown` tools, the + AND→OR planner semantics on `session_search`, and the structured + `ScopeError` diagnostic contract for both MCP servers. +- `session-export`: adds the non-fatal incremental ontology-refresh seam at + the end of `_run_export` and its recovery contract. +- `health-and-diagnostics`: adds ontology, concept-sidecar, and + MCP-registration checks with an explicit fatal-vs-report-only + classification. +- `configuration-and-secrets`: adds the generated-configuration requirement + that `memory.default_scope` is written explicitly as `unclassified`, + distinct from the runtime default that stays unset. + +## Impact + +- **Affected code (future, by task, not part of this change)**: `packages/ + agent-session-tools/src/agent_session_tools/{migrations.py, ontology.py + (new), context/*, sync.py, export_sessions.py, mcp_server.py, + config_loader.py}` and `packages/studyloop/src/studyloop/{settings.py, + parking.py, mcp/tools.py, mcp/server.py}`.

(Per design.md's B3 verification note, matrix item 4 was run against the unmodified reference allocator first and passes — the table-wide `MAX(logical_time)` already advances the next local lamport past every import, so no explicit advance-on-import step was added.) +- [x] 3.4 Freeze and document the `ConceptService` public API surface per design.md's compatibility seam before B4 can depend on it, and verify with an import/API-surface regression test. +- [x] 3.5 Run the 2,033-file legacy OKF import on an Online Backup, attach the bound/unbound report to this OpenSpec change, and verify the resulting counts against the A3b1 baseline with any delta explained; confirm `just preflight` is green and complete an independent review.

(Planner commit `fb33e2ce`; black-box identity tests preserve every non-widened golden case.) +- [x] 4.3 Implement `memory_recall` in `mcp_server.py` against design.md's frozen `RecallReport` contract, and verify with a JSON-schema test diffing the tool's output shape against `docs/data/recall-contract.json`.
