0.8.0 — Slice 5 (G1 structured SearchHit + FTS5 tokenizer) + Slices 0 close + HITL decisions#83
Merged
Conversation
HITL-approved 0.8.0 implementation plan and its supporting corpus, committed to give the Slice 0 agent a clean baseline (cold-start §12.2 + worktree baseline §1 both need these on main). Corpus: - dev/plans/0.8.0-implementation.md — the approved 9-slice plan (mod-5 numbering + reserved gaps; slice-orchestrator model; per-slice design→TDD→codex→fix-N discipline; cross-cutting X1 SDK parity+functional harnesses / X2 mkdocs build / X3 per-slice docs + dev/DOC-INDEX.md). - dev/design/0.8.0-agent-memory-fit.md — gap ladder G0–G12 + consumer fit (§9). - dev/design/0.8.0-v05-feature-triage.md — v0.5.x add/defer/drop triage. - dev/design/agent-memory-impl-strategy.md — per-gap leverage build plan. - dev/adr/ADR-0.8.0-supersede-five-verb-surface-cap.md (new) + ADR-0.8.0-agent-memory-retrieval-and-identity.md (scope reclass). - dev/roadmap/0.8.0.md — v0.5.x revival scope. - dev/profiling/ — ingest+retrieval stack profiling component guide. - dev/plans/prompts/0.8.0-PROF-*.md — ingest/retrieval profiler slice prompts. - dev/plans/runs/*.wf.js — the planning workflow scripts (resumable). Slice 0 (separate agent) executes next; this commit does not start execution. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…concile mkdocs nav, author substrate ADR, advance supersession ADR; advance pointer to Slice 5 Slice 0 [design-adr], no worktree, no code. Subagents 0.a ∥ 0.b (both spawned as subagent_type: implementer, no fallback) returned PASS against their bars. - 0.a: NEW dev/adr/ADR-0.8.0-canonical-identity-substrate.md — four substrate decisions settled (additive column shape; invalidate-not-delete; edges carry temporal cols = Q4 yes; op-store cascade); verbatim Slice-15 schema delta (logical_id+superseded_at on canonical_nodes AND canonical_edges; partial unique-active index; folded G4/G5 indexes; MIGRATION-ACCRETION-EXEMPTION; SCHEMA_VERSION 10->11); in-place additive migration policy; write_cursor-as- row-id deviation FLAGGED for HITL; shadow vec0/FTS5 reconciliation named as reserved Slice 16. - 0.b: advanced ADR-0.8.0-supersede-five-verb-surface-cap.md -> decision-ready (Q1-Q5 = A1/B1/amend/confirm/SDK-only; conformance rewrite enumerated not executed; three guarantees carried forward); authored 0.8.0-plan.md (mod-5 ladder) + STATUS-0.8.0.md (nine §12.5 sections + X1/X2/X3 column + witness + harness contract); created dev/DOC-INDEX.md (X3); reconciled mkdocs nav (added 0.6.1; 0.8.0 stub) + mkdocs build --strict green (X2). Adversarial review PASS. codex (--sandbox read-only) unrunnable here (bubblewrap net-namespace init failure; relaxation flags denied by harness classifier); substituted an independent adversarial subagent on the identical four-check + Slice-15 rubric. Verdict+provenance: dev/plans/runs/0.8.0-slice-0-review-20260602T115112Z.md (raw codex failure log alongside, .log). Witness: implementer subagent-type EXISTS + selectable (supersedes stale MEMORY orchestration-execution-traps note). Terminal Slice-0 exit = HITL gate-package sign-off (substrate gates Slice 15; supersession finalized at Slice 25). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
….0 ADRs in index
Recovery denylist (HITL decision 2026-06-02, 'five everywhere'): correct prose to
{recover,restore,repair,fix,rebuild} across bindings.md, the supersede ADR (element-3
table, preserves-verdict, Q4, Slice-15 guarantee), interface-inventory (x2), and
0.8.0-v05-feature-triage (x2). doctor is SDK-absent via the positive verb allowlist,
NOT this recovery-name denylist. The five-name enforcement artifacts
(test_no_recovery_surface py/ts/rs + AC-035d) stay byte-unchanged; prose now matches.
ADR index: add a Phase 0.8.0 section (#33-36) registering all four 0.8.0 ADRs in
ADR-0.6.0-decision-index.md, which agents must consult before scanning the tree.
Both issues surfaced by codex review across multiple rounds; final codex pass clean.

…leteness audit codex completeness audit of Slice 0 (HEAD a42f234) rated all six substantive deliverables PRESENT/MEETS-BAR and flagged only a literal reading of the 'no worktree outstanding' criterion: raw `git worktree list` shows two worktrees while the board ledger said 'empty'. Neither is a 0.8.0 slice-managed worktree (Slice 0 is design-adr and created none): - .claude/worktrees/agent-ad59c9d7bcc049a3d — locked prior-agent harness orphan (0.6.x commit 0debd6b, live pid); - .claude/worktrees/corpus-work — active owner-managed corpus-expansion branch. Make the §6 ledger precise: it tracks 0.8.0 slice-managed worktrees (none outstanding); the two pre-existing non-slice worktrees are out of scope and not Slice 0's to clean up. No worktree touched; no code; docs-only. Slice 0 remains CLOSED — deliverables complete; this only corrects board accuracy. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…rompt, record step-11 plan-adjustment + SearchHit/tokenizer compat-ledger ack Orchestrator bookkeeping (no code). Slice 5 (G1 structured SearchHit + global FTS5 tokenizer upgrade) advanced NEW→WORKTREE_CREATED: - Worktree /tmp/fdb-slice-5-20260602T215841Z @ branch slice-5-20260602T215841Z, baseline 944cbb4 (main HEAD; re-verified before `git worktree add`). - Self-contained 5.a implementer prompt: dev/plans/prompts/0.8.0-slice-5.md. - Plan-adjustment (§12.4): Slice 5's NEW tokenizer migration is step_id 11 and bumps SCHEMA_VERSION 10→11 (migrate requires contiguous step_id + open guard user_version<=SCHEMA_VERSION; witnessed max step=10). This re-numbers Slice 15 to step_id 12 / 11→12 (its "step 11 / 10→11" contract is now stale; reconciled at Slice 15 close). - Compat-ledger ack: breaking SearchHit data-class change + tokenizer recall shift accepted as documented 0.8.0 events (AC-057a-clean; no HITL sign-off needed). Board (STATUS-0.8.0.md): §1 current slice, §2 row ⏳, §6 worktree ledger, §7 decisions, §8 next-action resume loop updated. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…orktree; slice agent owns its worktree and merges to main HITL correction: the orchestrator must not create worktrees. The slice agent does implementation work on a worktree IT owns and merges its green work onto local main itself; the orchestrator works on main AFTER the merge (review → 5.b → close + advance pointer). Supersedes the orchestration.md main-thread-owns-worktree / cherry-pick mechanic for the 0.8.0 campaign. - Removed the worktree + branch I had erroneously created (/tmp/fdb-slice-5-20260602T215841Z, slice-5-20260602T215841Z); git worktree list clean. - Rewrote dev/plans/prompts/0.8.0-slice-5.md: §0 the slice agent creates its own worktree from live main HEAD; §5 it merges to main (no push) when green + output.json written; §7 output.json carries merged_to_main_sha. - Board: §1 state PROMPTED, §2 row, §6 ledger note (slice-agent-owned), §7 correction + PROMPTED entries, §8 next-action resume loop reworked to operate on main post-merge.

Recall floor 0.90 holds before AND after the tokenizer upgrade across the

…r upgrade (step 11, SCHEMA_VERSION 10→11)
…h in the step-11/reproject window Reconstructs the durable post-crash artifact (user_version=11 + empty search_index) on a real on-disk DB and asserts recall recovers on reopen. Fails on current code: the boundary-crossing guard (before<11 && after>=11) sees before==11 and skips the reproject, leaving the FTS shadow empty forever (recall 0.000). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The step-11 migration commits user_version=11 with an EMPTY search_index in its own transaction; the reproject that repopulates the FTS shadow ran in a SEPARATE later transaction gated on crossing the step-11 boundary (before<11 && after>=11). A crash after step 11 commits but before the reproject commits left a durable v11 + empty index on which the next open saw before==11, skipped the reproject, and stranded the index empty forever (recall collapses to ~0). Gate repair on the ABSENCE of a durable completion marker (_fathomdb_open_state['search_index_tokenizer_reproject_complete']) written INSIDE the same transaction as the reindex DELETE+INSERT, instead of on the boundary crossing. Atomic + idempotent: a crash before commit rolls both back (no marker -> next open re-runs); a crash after finds the marker and skips. Projection-only; SCHEMA_VERSION unchanged (still 11); no new migration step. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The marker-absence gate runs on every v11 open. Synthetic/legacy DBs whose user_version was stamped to 11 without running our migrations lack the _fathomdb_open_state table (created in step 1), so the marker read raised 'no such table' and masked the downstream embedder-identity / dimension mismatch errors (AC-048 / AC-048b). Treat a missing _fathomdb_open_state as 'reproject complete / nothing to do' so those DBs fall through to the embedder-identity probe unchanged. A genuinely migrated (crash-affected) DB always has the table, so crash-repair is unaffected. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…le (codex P1; state/marker-gated, not boundary-gated)
… (PASS after codex BLOCK→fix-1); advance pointer to Slice 10 Slice 5 merged to main by the slice agent (initial c4ab615; fix-1 e76d68b final). codex §9 review (primary, runnable here) found one [P1] crash-safety bug — the tokenizer reindex was gated on the one-time 10→11 boundary crossing, so a crash after step 11 commits (user_version=11, empty search_index) but before reproject commits left the FTS index empty forever. BLOCK→fix-1 made the reindex crash-retryable + idempotent via an atomic completion marker; codex re-review of the fix-1 diff: PASS, no findings. Close (docs-only): - Slice 5 CLOSED blocks in 0.8.0-implementation.md + 0.8.0-plan.md; pointer → Slice 10. - STATUS board: §1 current slice → 10, §2 table (5 ✅ + X1/X2/X3), §3 scoreboard (G1 ✅; recall floor held 1.000/1.000 across the migration), §6 worktree ledger (slice-5 worktree REMOVED), §7 decision record, §8 next action. - Renumber notes added: Slice 5 consumed step_id 11 / SCHEMA_VERSION 11, so Slice 15 becomes step_id 12 / SCHEMA_VERSION 11→12 (impl-plan Slice 15 heading + canonical identity ADR AUTHORIZED-delta). - Closure output.json + both codex review verdicts (slice-diff + fix-1) committed. Carried to HITL (environment-only, not a code defect): agent-verify.sh STRICT=1 fails AC-037 netns-deny-egress (no rootless userns in this sandbox).

… fusion_mode knob from Slice 10; AC-037 → CI at Slice 40
HITL signed the retrieval ADR (2026-06-02), unblocking Slice 10:
- Q1 = Option 1A: G9 RRF + G10 filtered-KNN both table-stakes, ship in Slice 10
(G10 uses a CLOSED SearchFilter struct; filter-grammar DSL stays Slice 35).
- Q2 = Option 2A: substrate designed bi-temporal-aware, implement single-supersession only.
- Q3 = documented-only, NO knob: RRF is the unconditional new ranking; the fusion_mode /
legacy-union escape hatch is DROPPED ("do not carry the overhead"). The entire Slice 10
contract is reconciled — every fusion_mode mention removed or marked NOT-fusion_mode;
G12-recency now gated behind a dedicated recency flag; the compat event is documented-only.
- Q4 = edges too: canonical_edges carry logical_id+superseded_at (schema-only).
- Q5 = advisory: §8d capability ladder stays advisory input, not canonical.
ADR status → accepted; added a "## HITL decisions (2026-06-02)" block.
STATUS board §5: retrieval package SIGNED (Slice 10 gate cleared); substrate package
partially signed (Q2/Q4 done; op-store cascade + migration policy + write_cursor deviation
still open before Slice 15). §1/§8 mark the Slice 10 gate cleared.
AC-037 (no-egress) disposition: can't run on windchill3 (Ubuntu 24.04 AppArmor
apparmor_restrict_unprivileged_userns=1) and runs in NO CI workflow. Accept-by-reasoning for
Slice 5 (no networking added); wire scripts/agent-security.sh into CI on a userns-permissive
runner as a NEW Slice 40 gate (n).

…t-Slice-5/fix-1); keep Slice 40 CI gate (n) HITL ran the gate on windchill3 with the AppArmor userns lockdown temporarily relaxed (kernel.apparmor_restrict_unprivileged_userns=0, restored to 1 after): AC-037 OK: all connect() syscalls were loopback / AF_UNIX / AF_NETLINK. This machine-confirms the merged Slice 5 + fix-1 code makes no network egress — upgrading AC-037 from accept-by-reasoning to confirmed. The one-time pass is point-in-time, so the continuous Slice 40 CI gate (n) is KEPT (wire agent-security.sh on a userns-permissive runner). Updated the Slice 5 close blocks (impl-plan + plan + board §1), board §5 disposition, and gate (n) note to reflect the confirmation. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
