From 6253940ed550461cd52ceb3901abc1f9cb900c18 Mon Sep 17 00:00:00 2001 From: Sachin Shelke Date: Fri, 29 May 2026 00:13:01 +0530 Subject: [PATCH 01/44] refactor(v3.0.1): extract jsonl_store amendment-overlay primitives MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds three free functions to jsonl_store.py that the five v3.1.0 memory subsystems (working, skills, activity, pending_conflicts, reflections) will reuse instead of each copy-pasting the merge dance: - read_merged(path, *, id_field, amendment_field) — the existing amendment-overlay logic from decisions_store._read_merged, with id_field / amendment_field knobs so non-decisions stores can reuse it. - compact(path, *, keep_predicate) — atomic predicate-based rewrite, needed for working-memory eviction during codevira sync. Preserves malformed lines (filtering ≠ corruption cleanup). - read_recent(path, *, limit, ts_field) — sort-by-ts-desc + slice, extracted from sessions_store.read_recent. Also documents the _schema_v: 1 convention for v3.1+ JSONL stores (decisions/sessions schemas unchanged — readers tolerate absence). decisions_store._read_merged and sessions_store.read_recent are re-implemented as thin one-line wrappers over the new primitives; zero behavior change for existing callers. 144 storage tests (including 20 new tests for the primitives + amendment-chain-three- deep recursion semantics from plan B3) pass green. Prerequisite for v3.1.0 memory subsystem work.

Every concurrent IDE (Claude Code, Cursor, Windsurf, Antigravity) and every unattributed agent collided into the same session_id bucket — masking real session boundaries in decisions.jsonl and breaking the v3.1.0 working-memory design which keys observations and conflict materialization by session_id. Adds decisions_store.default_session_id() returning f'ad-hoc-{secrets.token_hex(3)}' (e.g., ad-hoc-a1b2c3). Both record() and record_many() use it as the per-call default; explicit session_id from the caller still wins (no silent overwrite — agents that DO group their work keep their grouping). learning.record_decision() resolves the effective session_id up front and passes it explicitly to decisions_store.record() so the response echoed to the agent matches what's persisted on disk. Pre- fix, the response said 'ad-hoc' while the JSONL line carried the generated slug — caller-visible and persisted state were divergent. Test: tests/storage/test_decisions_store.py covers the helper, record(), and record_many() paths including the explicit-slug-wins guarantee and mixed batch case. Plan B1; v3.0.x prereq #2 of 3.

What's added: - mcp_server/storage/origin.py — the current_origin() helper. ide from $CODEVIRA_IDE env (defaults "unknown"). agent_model from $CODEVIRA_AGENT_MODEL (optional). host_hash = sha1(uuid.getnode() bytes + username)[:12] — MAC + username, SHA1, truncated. Privacy-preserving (no plaintext hostname/username leaks). Cached via lru_cache. - decisions_store.record(), record_many(), search() carry origin. - sessions_store.write(), write_many() carry origin. - check_conflict surfaces origin per conflict/duplicate entry. Backward compatibility: all v3.0.x records (no origin field) read cleanly through every existing path. Absence treated as ide="unknown". No data migration required. Tests: 17 new tests across test_origin.py, test_decisions_store.py (TestOriginTagging), test_check_conflict.py (TestM1OriginSurface). 602 tests across storage + ide_inject + check_conflict + learning + engine pass green. Zero regressions from baseline. Non-goals (deliberate, per plan): - Cross-machine consistency (v3.2+). - Tamper resistance (origin is informational, not security). - Retroactive origin backfill (would falsely attest authorship). Plan M1.

Per-project injectors stamped: - _inject_claude → "claude_code" - _inject_claude_desktop → "claude_desktop" - _inject_cursor → "cursor" - _inject_windsurf → "windsurf" - _inject_antigravity → "antigravity" Global injectors stamped: - inject_global_claude_code, inject_global_claude_desktop, inject_global_cursor, inject_global_windsurf, inject_global_antigravity. The Claude Code CLI install path (`claude mcp add`) also forwards `--env CODEVIRA_IDE=claude_code`. Best-effort: older claude versions without --env will fail the CLI call, and the existing fallback path (direct ~/.claude.json merge) sets env the same way. Implementation note: signature of _build_server_config / _build_global_server_config is unchanged — env stamping is done by mutating the returned dict at each per-IDE call site. This avoids the blast-radius veto on a private signature change and keeps the ide_key→env mapping visible at each injection point rather than hidden in a shared helper. Tests: tests/test_ide_inject.py::TestM1IdeEnvStamp — 8 assertions, one per per-project + global injector, plus an idempotency test. 86 existing ide_inject tests still pass (no regression on the preserve-existing-server-config invariants).

This is the foundation for M2 — the MCP tools (working_add/get/promote, get_working_context), engine post_tool_use fan-out, and get_session_context panel land on top in Phase 2/3. mcp_server/storage/paths.py — two additive helpers: * working_path() → .codevira-cache/working.jsonl (per-machine, ephemeral, gitignored). * working_archived_path(session_id) → .codevira/working_archived/.jsonl (canonical, gitable, opt-in commit target). Both helpers carry a doc note on locked decision D000012 — they are pure path computation, do not bypass ensure_dirs()'s forbidden-root validation, so the lock's invariant is preserved. mcp_server/storage/working_store.py — the store. API: * add(content, kind, importance, confidence, links, session_id) → W-id. Validates inputs (kind in {observation, goal}, content ≤ 2 KB, importance 1-10, confidence 0.0-1.0). Each record carries _schema_v: 1 + origin + W-prefixed monotonic id. * mark_evicted(wid, reason) — amendment tombstone. * mark_promoted(wid, target_id) — amendment with backref to LTM id. * list_top_k(top_k, kind, session_id, now) — decay-scored, tombstone-aware. Tombstones detected via _tombstoned_ids() pre-scan because read_merged deliberately filters underscore- prefixed fields when overlaying amendments (matches decisions semantics). * list_session_entries(session_id) — live entries for one session. * get(wid) — single-entry merged view. * compact() — two-pass predicate that drops both tombstoned bases and their amendment rows. Called by codevira sync. * commit_session(session_id) — copy live entries to .codevira/working_archived/.jsonl (opt-in promotion). Original cache file untouched. Idempotent append. Decay scoring: importance × exp(-Δt_hours / τ) + 0.5 × access_count, τ = 6h. Lazy on read; nothing on disk. Matches Generative Agents' additive composition; τ chosen for workday arc. Tests: tests/storage/test_working_store.py — 29 tests covering input validation, schema fields, decay formula, list_top_k ranking + filtering + tombstone exclusion, compact() drops base + amendment rows together, commit_session live-only + idempotent. 194 storage tests pass green; zero regressions from M1 baseline. MCP tool surface lands in Phase 2 (Task #7). Plan M2 Phase 1.

Capped ~150 tokens; entries truncated at 120 chars each. Designed for the M2 Phase 3 get_session_context panel. Tool surface — registered in mcp_server/server.py: - 4 Tool(...) entries in list_tools() under a 'v3.1.0 M2: working memory' comment block. Schemas use enum for kind / to fields so the IDE-side validators give early feedback. - 4 elif name == 'working_*' branches in call_tool() dispatch. Promotion contract: the to='decision' path encodes three guards beyond the storage layer's input validation: 1. Tombstoned entries cannot be re-promoted. 2. check_conflict runs before decisions_store.record. On conflict or duplicate, returns {_conflict_warning: ...} without writing. force=True overrides. 3. Promoting a kind='goal' entry surfaces an _intent_note in the response because goals are intents, not facts. Working-memory links and the source W-id are folded into the promoted decision's context so the audit trail survives. Tests: tests/test_tools_working.py — 22 tests across working_add, working_get, get_working_context, working_promote. 311 tests across server + storage + working + learning + check_conflict pass green; zero regressions from the M2 Phase 1 baseline.

charset=UTF-8 Content-Transfer-Encoding: 8bit Completes M2 by wiring the working_store (Phase 1) and MCP tools (Phase 2) into the agent's day-to-day flow. Engine memory_fanout (auto-population): New mcp_server/engine/memory_fanout.py. PostToolUse events get an observation written automatically: - Edit/Write/MultiEdit/NotebookEdit/update_node → 'touched ', importance 4. - Bash (non-trivial) → 'Bash: ', importance 3. Trivial commands (ls/pwd/cd/echo/cat/which/type) are skipped. - Any tool whose output dict has 'error' → importance bumped to 7. - All other tools (read-only, introspection) → no observation (avoids flooding the buffer with 'looked at' noise). R3 mitigation per plan: in-process buffer with _FLUSH_THRESHOLD=20. On the 20th event, the buffer drains to working.jsonl as one batch. atexit hook flushes on clean shutdown. Wiring: mcp_server/engine/wiring/mcp_dispatch.py.post_call calls memory_fanout.dispatch AFTER the existing engine dispatch returns. Sequenced so the verdict is unaffected by fan-out behavior; fan-out failure is logged and dropped (fail-open). get_session_context working panel: New 'working' field in the get_session_context payload — top-3 live entries (by decay score), content truncated at 120 chars. Returns {entries, count}. Best-effort: any failure surfaces an empty entries list rather than crashing the catch-me-up call. codevira working commit CLI: mcp_server/cli_working.py + 'working' subparser in cli.py. Surface: codevira working commit Copies a session's live (non-evicted) entries from .codevira-cache/working.jsonl to .codevira/working_archived/.jsonl. The cache file is left untouched so the agent can keep iterating; running the command twice produces an append (documented behavior). Tests: - tests/engine/test_memory_fanout.py (19 tests): observation builders per tool, error-bump, trivial-Bash skip, dispatch only on POST_TOOL_USE, threshold-triggered flush, manual flush, end-to-end visibility via working_get + error-rank-by-importance. - tests/test_tools_learning.py::TestGetSessionContext gains 3 tests: empty panel, populated panel, graceful failure. - tests/test_cli_working.py (6 tests): usage error, no-op on unknown session, copy live entries to archive, exclude evicted, idempotent appends, storage failure exits 1. Regression sweep: 635 tests across engine + storage + tools + check_conflict + CLI + server pass green. Zero regressions from M2 Phase 2 baseline. CLI smoke verified: 'codevira working --help' and 'codevira working commit --help' render correctly. Plan M2 Phase 3.

Skills encode 'how to do X in this project' as ≤ 2 KB markdown procedures the agent can record (explicit now; induced in M5) and retrieve when a similar task recurs. mcp_server/storage/paths.py — additive: skills_path() → .codevira/skills.jsonl (canonical, committed). Doc note on the D000012 lock — pure path computation, ensure_dirs() still owns WRITE-path validation. mcp_server/storage/skills_store.py — the store. API: * record(name, procedure, summary, triggers, source, source_session_ids, do_not_revert, origin_override) → K-id. Validates inputs (procedure ≤ 2 KB, summary ≤ 256 B, source ∈ {explicit, induced}). Each record carries _schema_v: 1 + origin + K-prefixed monotonic id + normalized tags + token estimate. * mark_used(skill_id, success) — reinforcement loop. Success increments success_count + resets consecutive_failures + revives an archived skill. Failure increments failure_count + consecutive_failures; at 5 consecutive failures (configurable) auto-archives unless do_not_revert=True. * set_flag(skill_id, do_not_revert, tags) — lightweight amendment. * mark_archived(skill_id, reason) — manual archive. Refuses to archive do_not_revert skills (canonical doctrine). * supersede(old_id, name, procedure, summary, triggers, reason, do_not_revert) — writes new skill + amendment chain. Triggers inherit from old when not supplied; back-references on both sides. * get(skill_id) — single-skill merged view. * list_all(status, source, tags, limit) — filtered list. Default status=active; tags filter is set intersection. * decay_sweep(now, unused_archive_days=90) — auto-archive active skills unused past the cutoff. do_not_revert exempt; already-archived skills not double-counted. For codevira sync. Lifecycle states (mirrors decisions' protected-set convention): - active — default. Returned by get_skill. - archived — low-value (5 consec failures or 90d unused). - superseded — replaced by a successor; final state. Tests: tests/storage/test_skills_store.py — 33 tests across record validation, mark_used reinforcement loop, set_flag, mark_archived, supersede chain, list_all filtering, decay_sweep. 227 storage tests pass green; zero regressions from M2 baseline. Plan M3 Phase 1. Phase 2 (FTS5 + 6 MCP tools) is next.

FTS5 skills table: mcp_server/storage/fts5_index.py — additive (existing decision callers unchanged): - New _SKILL_TABLE = 'skill_fts' coexists in the same .codevira-cache/fts5.sqlite file as decision_fts. Separate meta key ('skill_source_mtime') tracks the skills index independently from decisions. - rebuild_skills_from_jsonl(skills_path, index_path) — drop + recreate skill_fts from skills.jsonl. Skips superseded skills. - add_skill(index_path, skill) — incremental indexing, called from skills_store.record(). DELETE-then-INSERT for idempotency. - search_skills(index_path, query, limit) — BM25-ranked search; name 3.0 / summary 1.5 / procedure 1.0 weights. - skill_staleness_check(skills_path, index_path) — parallel to the decisions check; uses the dedicated meta key. Composite ranking (skills_store.search): mcp_server/storage/skills_store.py adds search() with the plan's formula: score = 0.5 × BM25_norm + 0.3 × tag_jaccard + 0.2 × recency_decay BM25_norm = -bm25_raw / max(-bm25_raw) (in [0, 1]) tag_jaccard = |query_tokens ∩ skill_tags| / |union| recency_decay = exp(-Δdays_since_last_used / 30) recency_decay scores 0 for never-used skills — recency is a *usage* signal, not an existence signal. skills_store.record() now calls fts5_index.add_skill (best-effort, P9 — never blocks the write). 6 MCP tools (mcp_server/tools/skills.py + server.py registration): - record_skill — runs check_conflict on SKILLS corpus first; force=True overrides. - get_skill — composite-ranked hits with score_breakdown. - apply_skill_outcome — manual reinforcement override. - list_skills — daily-driver active list by default; status='all' returns every state. - supersede_skill — version a skill with amendment chain. - promote_skill_to_playbook — writes the procedure as .codevira/playbooks//.md. Refuses overwrite without force=True. Registered via 6 Tool(...) entries in list_tools() and 6 dispatch branches in call_tool(). Tests: - tests/storage/test_skills_store.py::TestSearch (10 new): empty query, finds by text, excludes archived/superseded, tag jaccard boosts score, recency uses last_used_at, file_path filter, weights overridable, top_k cap, lazy rebuild on stale index. - tests/test_tools_skills.py (27 new): record_skill validation + force override, get_skill response shape + file_path filter, apply_skill_outcome variants, list_skills filters, supersede chain, promote_skill_to_playbook (write, refuse-overwrite, force-overwrite, explicit name, unknown skill, superseded rejection, empty task_type, unslugifiable name). 799 tests across storage + tools + check_conflict + server + ide_inject + engine + cli pass green; zero regressions from the M3 Phase 1 baseline. Existing fts5_index tests (decisions) unchanged. Plan M3 Phase 2. M3 complete; M4 (spatial memory) is next.

Each record carries _schema_v: 1 + origin + A-prefixed monotonic id + session_id (defaulting to ad-hoc-XXXXXX). * list_recent(limit, kind, node_id, since) — newest-first activity feed with AND-filter composition. * list_top_k_files(top_k, since, weights) — weighted heatmap. Default weights: edit=1.0, decision_ref=2.0 (a decision tied to a file is a stronger 'attention' signal than a single edit). Overridable per-call. * visit_count_30d(node_id, now) — rolling-window counter for spatial_nearby ranking in Phase 2. * compact(retention_days=90) — drop rows older than the retention window. Called by codevira sync. memory_fanout integration: * _build_observation tags file-edit observations with a hidden _activity_file_path field carrying the file path. * flush() detects the field and writes an activity row alongside the working observation. Bash and unknown-file-path edits skip the activity write (preserves the 'did this' signal density). Best-effort: activity errors don't affect the working memory write. decisions_store integration: * record() with file_path emits a decision_ref activity row. Best-effort (P9) — the decision is already persisted. Schema: in v3.1.0 node_id is per-file. Per-symbol granularity needs graph.sqlite schema changes and is deferred to v3.2+. The plan-reserved 'visit' kind for read-only tools is deliberately NOT emitted; spatial heat surfaces edits + decisions, not lookups. Tests: tests/storage/test_activity_store.py — 23 tests covering add() validation, list_recent filters, list_top_k_files weighted ranking, visit_count_30d rolling window, compact retention drop, memory_fanout integration (Edit produces BOTH working + activity; Bash produces only working; unknown file_path skips), and decisions_store integration (file_path → decision_ref). 680 tests across storage + engine + tools + check_conflict + CLI pass green; zero regressions from the M3 baseline. Plan M4 Phase 1. Phase 2 (folder-tree neighborhoods + affordances + 4 spatial MCP tools) is next.

The agent can now ask 'what's near this file?', 'where has attention been?', 'what neighborhood am I in?', and 'what can I do here?'. spatial.py — 4 MCP tools: * spatial_nearby(file_path, k) — BFS distance ≤ 2 over the indexer graph (imports + call edges) ∪ same-neighborhood. Ranking: (1 / (1 + bfs_dist)) × log(1 + visit_count_30d). Falls back to neighborhood-only if the indexer graph isn't built. * spatial_heat(top_k, since_days) — top-K most-touched files by weighted activity. * spatial_neighborhood(file_path) — folder-tree default (top-2 dir components — 'mcp_server/storage', 'indexer'), overridable via .codevira/neighborhoods.yaml. * spatial_affordances(file_path) — affordance keys (task_types) for the file based on bundled + project affordances.yaml. Folder-tree neighborhoods drop the filename then cap at depth 2: - mcp_server/storage/foo.py → 'mcp_server/storage' - indexer/foo.py → 'indexer' - README.md → '' Override file .codevira/neighborhoods.yaml RE-LABELS matched files; files matching nothing fall through to the folder-tree default (the override never hides files). mcp_server/data/affordances.yaml — bundled defaults: tools/ → {add_tool, write_test}; storage/ → {add_store, write_test}; indexer/ → {add_parser_rule, write_test}; test files → {write_test, debug_pipeline}; Makefile/pyproject/CHANGELOG → release + commit affordances. Project override at .codevira/affordances.yaml; loader concats bundled+project and returns the union per match. Already covered by pyproject's package-data glob (mcp_server/data/**/*). Server.py: 4 Tool(...) entries in list_tools() + 4 dispatch branches in call_tool(). Tests: tests/test_tools_spatial.py — 28 tests covering folder-tree shapes, yaml override + fall-through + malformed-fallback, members from activity log, affordance patterns (bundled + override union), spatial_heat ranking + since_days, spatial_nearby graph-missing fallback + self-exclusion + activity ranking + isolated file, _node_id_to_file_path edge cases. 756 tests across storage + engine + tools + check_conflict + server + CLI pass green; zero regressions from M4 Phase 1. Plan M4 Phase 2. M4 complete; M5/M9 next per the plan's phasing.

Three pieces: Sessions schema (sessions_store.py): Additive optional fields on every session log: - task_type ∈ {feature, bug, refactor, release, docs, other} - skill_ids: list of K-ids used during the session Legacy v3.0.x sessions tolerate absence; the induction pipeline + outcomes-fan-out simply skip sessions without these fields. outcomes_writer skill fan-out (outcomes_writer.py): When observe_all() classifies a session's decision as 'kept' or 'reverted', each skill referenced via skill_ids on the SAME session gets a corresponding mark_used call: - kept → skills_store.mark_used(success=True) - reverted → skills_store.mark_used(success=False) - modified → no-op Pre-builds a {session_id → set[skill_id]} index so the per-decision fan-out is O(1) lookup. Fail-open: skills_store errors log a warning but don't fail the decision-outcome write. Summary dict gains skill_marks_success / skill_marks_failure counts so the CLI can surface the fan-out totals. This is the canonical reinforcement signal — git-derived, not agent-self-reported. The MCP-tool apply_skill_outcome remains as a manual override. codevira induce-skills CLI (cli_induce.py): Deterministic induction pipeline (no LLM in v3.1): 1. Filter to sessions with task_type + ≥80% of classified decisions marked 'kept'. 2. Group by task_type. 3. Cluster within each group by tag-Jaccard ≥ 0.5 (greedy single-pass agglomeration). 4. Keep clusters with ≥3 sessions. 5. Render candidate skill per cluster: name = ': ' procedure = bullet-summary of session.task + truncated decision.decision (capped at 30 lines). 6. Without --apply: write to .codevira/induction_proposals.jsonl. 7. With --apply: interactively confirm each (use --yes to skip prompts in CI). Records via skills_store.record( source='induced', source_session_ids=[...]). paths.induction_proposals_path() + cli.py 'induce-skills' subparser wire the surface. Tests: tests/test_cli_induce.py — 15 tests covering _jaccard, _build_proposals (empty, below-threshold, below-min-cluster, productive cluster, distinct task_types, low-jaccard), cmd_induce_skills (dry-run + apply --yes), and outcomes_writer fan-out (kept→success, reverted→failure with monkeypatched classification). 742 tests across storage + engine + tools + check_conflict + CLI pass green; zero regressions from M4 baseline. Plan M5. Reinforcement loop closed; M6/M7 (consensus) and M8 (reflections) remain.

No amendment rows are written on decisions; the handshake protocol where one IDE proposes a supersession is M7 (opt-in, default off). Storage layer (consensus_store.py): - Per-IDE checkpoint at .codevira/checkpoints/.json, keyed on last_seen_decision_id. Plain string ordering works because IDs are zero-padded base-36 — no clock drift exposure. - append_conflict / list_pending — PC-prefixed append-only log. - scan_and_materialize(): 1. Resolve current_ide from CODEVIRA_IDE env (bails out cleanly when 'unknown' so we don't materialize garbage). 2. Pull decisions via decisions_store._read_merged (skips superseded). 3. Filter to decisions with id > checkpoint. 4. Partition by origin.ide into current_corpus + foreign. 5. For each foreign × current_corpus pair, run check_conflict tokenize/Jaccard/overlap math. Record duplicate or asymmetric-conflict matches. 6. Advance the checkpoint to the max id seen. Reuses the existing _tokenize / _jaccard / _overlap_coefficient helpers from check_conflict so the conflict-shape math is one source of truth. CLI + MCP tools: - 'codevira consensus check' (cli_consensus.cmd_consensus_check) runs the scan and prints a summary. Exit 0 always. - consensus_check MCP tool: same scan, returns the summary dict. - consensus_status MCP tool: count + top-K rows for surface rendering. Reused by the get_session_context panel. get_session_context gains a 'consensus' field with pending_count + top-3 rows ordered by (do_not_revert × recency). Capped at ~200 tokens worth of summary. Best-effort: any storage failure surfaces an empty count rather than crashing. Schema additions: - paths: pending_conflicts_path() + ide_checkpoint_path(ide_key). - PC-prefixed monotonic IDs. - Each row carries _schema_v: 1 + current_origin + foreign_origin so future readers can reconstruct the cross-IDE context. Tests: tests/test_cli_consensus.py — 16 tests covering checkpoint roundtrip + malformed recovery; scan_and_materialize (unknown-IDE bail, no-foreign, foreign-duplicate, checkpoint advancement, second- scan delta, superseded skipped); cmd_consensus_check stdout; consensus_check / consensus_status MCP tools; get_session_context consensus panel (empty + populated). 758 tests across storage + engine + tools + check_conflict + CLI pass green; zero regressions from M5 baseline. CLI smoke verified: 'codevira consensus check --help' renders cleanly. Plan M6. M7 (Phase C handshake) and M8 (reflections) remain.

charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the belief-revision handshake protocol that lets one IDE propose superseding a do_not_revert decision authored by a different IDE. Gated behind memory.consensus.handshake_enabled (default False) so the v3.1.0 ship doesn't change semantics for users who haven't opted in. Config helper (config.py): tiny accessor over .codevira/config.yaml. get_flag(path, default) for dotted lookups; is_enabled wraps for boolean toggles. Fail-open on missing file / malformed yaml. Storage layer (consensus_store.py): - propose_supersession: validates target; same-IDE fast-path returns {fast_path: True}; cross-IDE appends a proposed_supersession row with expires_at = ts + handshake_timeout_days (default 14). - resolve_proposal: appends resolution row with resolver_origin; action ∈ {approved, rejected, withdrawn}. - find_proposal / find_latest_resolution / proposal_status: derive status from base + latest resolution + expiry. Last resolution wins. - finalize_proposal: convert approved proposal to a real supersession via decisions_store.supersede. Expired proposals require expired_unilateral=True (deadlock safety) — and write an audit row recording the force-finalize. - list_proposals: filtered list with derived status. Row kind taxonomy in pending_conflicts.jsonl: - 'conflict' (M6 read-only) - 'proposed_supersession' (M7 proposals) - 'resolution' (M7 approve/reject/withdraw) MCP tools (tools/consensus.py): - consensus_propose_supersession (opt-in) - consensus_resolve (opt-in) - origin_of (always available) Registered in server.py: 3 Tool entries + 3 dispatch branches. Schemas enforce action enum for early validation. Tests: tests/test_consensus_handshake.py — 24 tests covering config helper, propose (unknown target, cross-IDE, same-IDE fast path), lifecycle (pending/approved/rejected/withdrawn/expired, latest-wins, bad action), finalize (pending blocked, approved finalizes, expired requires unilateral flag, audit row on force- finalize), MCP feature-flag gate. 782 tests across storage + engine + tools + check_conflict + CLI pass green; zero regressions from M6 baseline. Plan M7. M8 (reflections) and M9 (docs) remain.

charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the durable LLM-abstraction subsystem. Reflections live in .codevira/reflections.jsonl (canonical, committed) — Generative- Agents-style abstractions over recent decisions + sessions that the next agent can read on get_session_context. Sampling integration scope: v3.1.0 ships storage + sanitization + source-context builder + prompt template + the API surface. The MCP sampling/createMessage RPC that asks the host LLM for the abstraction is the v3.2 deliverable. Until then, reflect() returns {sampling_supported: False, rendered_prompt, source_context} and the CLI accepts an LLM response via --from-file. Storage layer (reflections_store.py): - scrub_sensitive(text): regex redaction of api keys / Bearer / passwords / AWS AKIA / long hex / long base64 → . - build_source_context(period_days, now): aggregate sessions + decisions in window; plan caps (≤30 / ≤100 / ≤6 KB); sanitize narrative fields; envelope trim drops oldest first when over. - render_prompt(ctx): inline source into bundled prompt template (mcp_server/data/prompts/reflection_v1.md). Fallback inline when template missing. - append(target='reflections'|'proposals'): write finalized or pending; R-prefixed monotonic ids. - list_recent / list_filtered: newest-first reads with since/tags. CLI (cli_reflect.py): codevira reflect [--period 7d] [--from-file PATH] [--apply] [--yes]. - No --from-file: render prompt and print it. - --from-file PATH: parse the LLM YAML response (first ```yaml fence or whole-text fallback); write to reflection_proposals.jsonl. - --from-file PATH --apply [--yes]: commit to reflections.jsonl (interactive confirm unless --yes). Empty abstraction rejected with non-zero exit. MCP tools (tools/reflections.py): - reflect(period_days, dry_run): {sampling_supported: False, deferred_to: 'v3.2', rendered_prompt, source_context, ...}. - get_reflections(top_k): newest-first reflections. - list_reflections(since, tags, limit): filtered list. Registered in server.py: 3 Tool entries + 3 dispatch branches. Bundled prompt: mcp_server/data/prompts/reflection_v1.md (single yaml-fenced output with abstraction/tags/confidence; ships via existing pyproject 'mcp_server/data/**/*' package-data glob). Tests: tests/test_reflections.py — 26 tests across scrub_sensitive (per-pattern + plain text untouched), build_source_context (window filter + caps + sanitization), render_prompt (template inline + fallback), storage (append / list_recent / list_filtered), CLI (render mode + --from-file proposal + --apply commit + unfenced parsing + missing file + empty rejection), MCP tools (reflect stub + get_reflections). 808 tests across storage + engine + tools + check_conflict + CLI pass green; zero regressions from M7 baseline. Plan M8. M9 (docs + verification smoke) is the only remaining milestone.

Walks through working memory (4 tools), skill library (6 tools), spatial memory (4 tools), consensus (5 tools spanning Phase B and the opt-in Phase C handshake), and reflections (3 tools). - CHANGELOG.md gains a comprehensive 3.1.0 entry covering all 8 milestones (M1 origin tagging, M2 working memory, M3 skill library, M4 spatial memory, M5 induction wired to outcomes, M6 consensus check, M7 handshake, M8 reflections). Also covers the v3.0.x storage prereq (jsonl_store primitives + session_id uniqueness fix). - pyproject.toml + mcp_server/__init__.py bumped to 3.1.0. Verification smoke: - Full test suite: 2282 passing, 57 pre-existing environmental failures (treesitter grammars / pyyaml absence — same baseline as v3.0.0). - Wheel builds cleanly to codevira-3.1.0-py3-none-any.whl; installs in a fresh venv; reports 'codevira 3.1.0' on --version. - All 4 new CLI subcommands surface in the installed wheel: 'codevira working', 'codevira induce-skills', 'codevira consensus', 'codevira reflect'. Each --help renders the documented options. Plan M9. v3.1.0 is feature-complete; the remaining v3.2 work is the live MCP sampling/createMessage RPC integration for the reflections subsystem.

With more than a handful of decisions the view became unreadable. This rewrites the embedded JS to make the viewer properly interactive while leaving the Python rendering pipeline unchanged (template placeholders, XSS escape, and structural test expectations all preserved). # Interactivity - **Pan**: drag empty canvas to translate the viewport. - **Zoom**: mouse wheel zooms in/out, centered on the cursor. Min 0.2x, max 6x. - **Drag nodes**: click+drag a node to pin its position; the incident edges update in place without a full re-render. - **Hover focus**: hovering a node highlights it + its 1-hop neighbors with stroke white-up; everything else dims. - **Controls bar** (top-right): Fit, ＋, －, ↻ Layout buttons for explicit control. # Clutter cleanup - **Labels hidden by default**, shown only when (a) the node is hovered, (b) a filter term matches it, (c) the zoom is ≥ 1.4x, or (d) the new 'always show labels' checkbox is on. - **Node size by degree** so hub decisions are visually obvious rather than indistinguishable dots. - **Initial seeding by degree**: high-degree nodes seed near the center on inner rings; periphery falls to outer rings. The force layout then refines, but starts from a readable shape instead of a random ball. - **Fit-to-view on load + resize** so the graph stays usable when the window changes. - **Layout reset button** un-pins every node + re-seeds + re-runs the layout — recovery path when manual drags get out of hand. # Same tests still pass tests/test_cli_graph.py — all 9 tests pass: - Structural assertions (placeholders filled, DATA inlined, self-contained / no CDNs). - XSS escape (\u003c/script>). - cmd_graph exit codes + lineage rendering. Manual smoke: generated a viewer over an 8-decision seeded project; HTML is 19.7 KB, self-contained, contains all new wiring (#viewport, btnFit, attachDrag, focusNode, fitToView), no leftover @@ placeholders. # Note on the previously-reported 'pre-existing environmental # failures' (57 tests) After installing the project editable in a clean venv ('pip install -e .' inside a venv), 2339 tests pass and 0 fail. The failures were running pytest from system Python where pyyaml + tree-sitter + mcp live in user-site, and several tests sanitize HOME for sandbox-testing — which strips user-site discovery. Documented workflow: contributors should run the suite from a venv. No code change required for that.

Three issues a real user would have hit: 1. **Search re-scored on every keystroke (perf).** renderRankedAndAsk walks all DATA.nodes per input event; at the 2000-node cap that's measurable lag while typing. Added 120ms trailing-edge debounce on the search input. Type-then-look still feels instant; bursty typing coalesces. 2. **Outcome lens leaves files/skills/reflections gray** because they have no `outcome` concept. The legend showed 'unclassified (N)' alongside the gray swatch — easy to misread non-decision nodes as "unclassified decisions". Added a 'decisions only' italic note to the legend. 3. **Lineage-trace mode + hover focus competed.** Hovering a node inside lineage mode would re-apply focus dimming on top of the lineage chain emphasis, producing flicker. focusNode now early- returns when lineageActive is true; the only way to use hover- focus is to Esc out of lineage mode first. Tests: 40/40 graph tests still pass. JS syntax-check clean (243 KB).

The cross-tool wedge — codevira's whole reason to exist — silently stopped propagating single-FTS-match decisions to other IDEs. # How it slipped past the gate D000010 requires `make test-e2e` BEFORE any engine-policy change. The procedural gate ran (39 passed). BUT the gate was structurally incomplete: it only invoked test_first_contact.py + test_product_invariants.py — it did NOT include test_cross_tool_universality.py, which is exactly where the single-FTS-match wedge regression lives. So the lock fired (good), I ran the gate (good), the gate said pass (misleading), and the regression shipped past three commits before the full `pytest tests/` (no --ignore) caught it during a final paranoia pass. Trust-loss anti-pattern. # Fix 1. Restore _DEFAULT_MIN_SCORE = 0.10. The threshold was load-bearing for the wedge contract; the 0.25 noise-reduction was a wash if it kills the core feature. 2. Widen `make test-e2e` to include test_cross_tool_universality.py. Future engine-policy changes will get caught at the right gate. # What the original bump was trying to fix Auto-surfaced prior decisions can feel noisy (D00005N meta-review called this out). The right approach is NOT lowering the threshold; it's raising per-source weights to compensate, OR adding a recency penalty for stale tags, OR moving noise-reduction to the inject layer rather than the rank layer.

That broke a load-bearing scenario: a Tool A decision with no tag/file overlap to Tool B's prompt — the score reduces to FTS_WEIGHT(0.2) × outcome_weight(0.5) = 0.10, exactly at the old threshold. With the new 0.25, it stopped injecting silently. The existing unit tests in TestScoringComponents are TOLERANT (`if verdict.action == "inject"`), so they passed. The test_cross_tool_universality e2e tests caught it BUT were not in `make test-e2e` at the time of the bump. # What this test pins The minimum-signal cross-tool wedge: - prompt mentions text from a decision - no tag overlap, no file overlap - score = TAG(0)+FILE(0)+FTS(0.2) × outcome_weight(0.5) = 0.10 - MUST clear _DEFAULT_MIN_SCORE and inject If a future change tightens the threshold or weights, this test fails immediately at unit level (not just e2e), and the failure message names the specific regression class. # What this test deliberately does NOT do It doesn't pin the score model itself (weights, threshold). The team can re-tune the scoring; what it CAN'T do is silently kill this minimum-signal path. The test will need an update if the score model changes, which forces deliberate review of the wedge contract. # Noise-reduction itself: deferred The original motivation for the 0.25 bump (surfaces feel noisy) was subjective, not measured. Real noise reduction needs: - a measurement (count of surface events per N prompts) - a benchmark of "useful surface" vs "noise surface" - a tuning loop that holds the wedge invariant fixed Deferred until those exist.

"who decided X" / "which IDE decided X" → groups matching decisions by ide, surfaces cross-tool authorship that's invisible in the rank-only view. - "when did we X" / "timeline of X" → chronological sort with first/last dates and date-stamped result list. - "compare X and Y" / "X vs Y" → two-column side-by-side of the top match per topic, with outcome/protected badges. Each follows the existing _scoreForQuery + filter pattern so behavior is consistent with the v3.1.x ranked search. Cheatsheet in qHelp updated to surface the new vocab. Drift-guard tests in test_cli_graph.py extended to require the three new JS symbols + the cheatsheet phrases.
