From 5b60dd44ee0f34143a284d3c71fa2c26a8986939 Mon Sep 17 00:00:00 2001 From: Tajudeen Date: Fri, 12 Jun 2026 04:05:03 +0100 Subject: [PATCH 01/46] phase4(rag): structured queryStructured() fixes the bogus-URI consumers RepoIndexerService.query()/queryWithMetrics() only ever returned formatted citation STRINGS ("File: :\nSymbols...\nContent preview..."), so the two consumers that need the matched file -- codebaseQueryCommands (Query Codebase quick-pick) and the agent's search_for_files indexer path -- were doing URI.file(), producing a bogus URI that opened/paged nothing. Add queryStructured(text,k): Promise returning the discrete hits (each with a real file URI). It shares one private _queryWithStructured() core with queryWithMetrics(): a `structured` array is pushed in lockstep with the string `results` at both assembly sites (common-query-cache + main path), threaded through the query/common caches, and returned. query()/queryWithMetrics() stay byte-identical (string assembly untouched; structured is purely additive). The context-cache fallback has no per-result URI, so it returns no structured hits. Point both consumers at r.uri (deduped by file -- a file can match via multiple chunks/symbols). Pins a structured<->formatted consistency test (the citation embeds the discrete uri verbatim). tsgo 0; 611 node tests pass.

The tool expanded a replace_all edit into N IDENTICAL Search/Replace blocks and fed them to the span engine (computeSearchReplaceResult), whose findTextInCode rejects a non-unique ORIGINAL as 'Not unique' -- so block 0 failed immediately (and even past that, all N identical blocks resolve to the same indexOf span -> 'Has overlap'). So replace_all=true on any string occurring 2+ times applied nothing. The model-facing prompt was also wrong: it claimed replace_all=false "replaces only the first", but the engine actually requires the match to be unique. Fix: a pure, node-tested common/multiEdit.ts computeMultiEditResult(content, edits) that applies the edits as the standard multi-edit transaction: - SEQUENTIAL: each edit operates on the text the prior edits produced. - replace_all=false: old_string must be UNIQUE (same indexOf===lastIndexOf test as findTextInCode, so a single edit matches edit_file's behavior); else 'Not unique' / 'Not found'. - replace_all=true: replace every left-to-right non-overlapping occurrence (>=1). - ALL-OR-NOTHING: validates+rewrites a local copy; the first failure returns ok:false with no newContent, so the caller throws before any write. toolsService.multi_edit now computes the final content via this and applies it through the existing instantlyRewriteFile diff path (the same one rewrite_file uses); computeSearchReplaceResult / edit_file are untouched. Prompt corrected to document the sequential + unique-or-replace_all semantics. Tests: 15 unit cases + a differential fuzz (20k single verbatim-substring edits + 5k independent full-line multi-edits) proving byte-identical results vs computeSearchReplaceResult on the inputs the old engine accepted (0 mismatch), so the swap is non-regressing while additionally fixing replace_all. tsgo 0; 628 node tests pass.

Release in both. 2. chatLatencyAudit fallover ORPHAN. finalRequestId is `const`, declared before the retry loop, so the retry reuses it -- but the model-fallover path started a context under a throwaway newRequestId the retry never used, orphaning a context (+ interval) that was never released. Re-arm under finalRequestId instead, which also restores latency tracking for the fallover attempt (onError released the prior attempt's context just before). 3. startBackgroundAgent hidden-thread leak. The hidden thread was added to allThreads but never removed, so every background-agent run left a thread object behind forever. Confirmed it is NOT user-inspectable (in-memory only, never in openTabs; the Running-agents panel renders the record's resultSummary, never the thread), and the summary is captured before cleanup -> drop the thread in a .finally() once the run settles (completed / errored / cancelled). 4. Anthropic streamed tool-name concat. content_block_start did `fullToolName += name` per tool_use block, so parallel tool calls concatenated into a garbage streamed name like "read_filelist_dir"; finalMessage already uses tools[0]. Keep only the first block's name. All four are in the browser agent loop / electron-main provider (excluded from the node runner), so they are verified by code reasoning, not unit tests; chatLatencyAudit releaseContext is idempotent and the lifecycle is now release-on-every-terminal-exit. tsgo 0; 628 node tests still pass.

Each `.cortexide/skills//SKILL.md` (Markdown + optional name/description frontmatter) becomes a `/ [args]` slash command in chat: invoking it expands the skill's instruction body (plus the user's args) into a normal chat turn. Pure testable core (common/cortexideSkillsService.ts, mirrors cortexideAgentsService): - parseSkillFile(dirName, text, uri): frontmatter + instruction body, no YAML dep. - parseSkillInvocation(input): "/name args" -> { name (lower-cased), args } | null. - buildSkillInvocationMessage(skill, args): the expanded turn text. - CortexideSkillsService: discovers each sub-dir of .cortexide/skills that holds a SKILL.md (recursive FS watch, 64 skills / 64 KB caps), getSkill() by name. Wiring: chatThreadService imports the service (registering the singleton) and exposes getSkillExpansion(input) + listSkillNames(); the chat input's slash handler (SidebarChat) dispatches in its default case AFTER the built-in commands (so a built-in like /help is never shadowed by a same-named skill), and /help now lists the available skills. Tests: 16 pure unit cases (parse / invocation / message-build, incl. CRLF, quoted frontmatter, multi-line args, lone-slash, dir-name default). tsgo 0; buildreact clean; 644 node tests pass. The discovery service (FS watch) and the React slash handler are browser-layer (not node-testable); verified by tsgo + buildreact + the pure-core tests -- a live CDP drive needs a workspace skill file (follow-up).

Add it as a 7th channel. Its status is computed via the telemetryConsent SSOT (isTelemetryEnabled), using the SAME local-only resolution the electron-main metrics gate uses (routingPolicy==='local-only' OR localFirstAI), so the report can't disagree with what actually ships: - opt-IN by default: OPT_OUT_KEY absent/'true' -> 'not-configured' (nothing sent) - explicitly opted in ('false') and not local-only -> 'open' - opted in but local-only -> 'blocked' (forced off, with a reason) The privacy-report command reads OPT_OUT_KEY from IStorageService at APPLICATION scope (shared with main) and threads it into the report config. Added 'telemetry' to EgressModality (+ a canEgress case to keep the switch exhaustive/total). Tests: a dedicated telemetry-channel test (default off / opt-in open / local-only forced off via both routingPolicy and localFirstAI) + updated the minimal-report count. tsgo 0; 645 node tests pass.

Replace it with a pure, deterministic, server-keyed prefix (new common/ mcpServiceTypes.mcpToolNamePrefix, FNV-1a -> 6 chars of [0-9a-z]). All tools from one server now share one stable prefix. Safe because routing uses the separate serverName (not the prefix) and the prefix is '_'-free, so the call-time strip removeMCPToolNamePrefix still recovers the original tool name. Threaded serverName through the 5 call sites. Tests: determinism, distinctness across server names, 6-char base36 / no '_', and round-trip through removeMCPToolNamePrefix for tool names containing underscores. tsgo 0; 649 node tests pass.

Extract it to pure common/autoApprovePolicy.ts (computeAutoApproveBaseline + decideAutoApprove) preserving the EXACT override order: catastrophic-command hard-block -> setting baseline ('edits' defaults true) -> dangerous-command force approval -> cwd-escape force approval -> YOLO NL-safe approve -> HIGH-risk-edit force approval -> YOLO edit approve. The caller computes the scalar inputs (classifyCommandRisk, the NL heuristic, scoreEdit) then makes ONE decision; telemetry / the hard-block message / the auto-apply notification stay inline, gated on the decision's per-rule flags so they fire under identical conditions with identical payloads. The NL+edit telemetry keeps its original try/catch swallow; the terminal telemetry stays un-wrapped (parity). Tested: golden table over every override + a 30k differential fuzz that re-implements the OLD inline mutation order independently and asserts the extracted decision matches on every input combination (0 mismatch). A 3-lens adversarial verification workflow (telemetry / control-flow / computation-order) confirmed full side-effect + control-flow parity; the one exception-propagation delta it found is now fixed. tsgo 0; 672 tests.

Extract everything except factor #6 (the count of pre-existing Error markers, which needs the live model/markers) into pure common/editRiskScore.ts scoreEditFromContext(context, existingErrorCount). The service now computes only that count -- passing 0 when the model is unavailable or there's no newContent, mirroring the old `if (model && newContent)` guard -- and delegates. EditContext/EditRiskScore types moved to the pure module and re-exported from the service so existing import paths are unchanged. Byte-identical logic. Tested: factor-by-factor golden cases (deletion=HIGH+1.0, critical +0.5, >50% rewrite crosses HIGH, test-file +0.2, multi-file cap, >5-errors +0.2, create floor 0.05, tiny edit very-low) + the LOW/MEDIUM/HIGH classifier boundaries incl. the silent-auto-apply boundary (riskScore<0.2 AND confidence>0.7). tsgo 0; 685 tests.

Extract it to pure common/perHunkAccept.ts: - computeAcceptedOriginalCode(originalCode, diff): folds an accepted hunk into the diff-area baseline (deletion/insertion/edit splices), byte-identical to acceptDiff. - computeRejectWrite(diff, diffAreaEndLine) -> {writeText, toRange}: the write+range that undoes a hunk, incl. the two end-of-zone rounding cases (deletion past the zone end, insertion of the final newline). Range is a plain IRange-shaped object (no editor import); the service passes it straight to _writeURIText. Tested: golden splices + golden range math for every variant and both end-of-zone boundaries, PLUS a 12k accept-convergence property fuzz -- repeatedly accepting the first hunk and re-diffing (exactly as the service does) must fold originalCode all the way to the new code. That sequential-accept path is where the boundary off-by-ones live. tsgo 0; 704 tests.

Add a randomized streaming fuzz: 2k random multi-block SR strings fed prefix-by-prefix must never regress (block count non-decreasing, per-block state never goes done->writingFinal->writingOriginal), and the complete stream parses to exactly N done blocks. The fuzz surfaced a real parser CONTRACT: a block with an EMPTY ORIGINAL is mis-parsed (the `=======` on the line right after `<<<<<<< ORIGINAL` is swallowed as content), while an empty UPDATED parses fine -- pinned as an explicit test so callers know ORIGINAL must be non-empty (realistic: you never search for nothing). Also deleted the ~200-line commented-out test corpus from the source (it lives in the runnable suite now). tsgo 0; 706 tests.

Extract the pure cores to common/providerToolFormat.ts: - extractToolCallFromNonStreamingChoice(choice): {empty, hasToolCall, text, name, args, id}. The caller keeps the original `if (toolCalls.length>0)` guard via hasToolCall, so a prior streaming attempt's tool vars aren't clobbered. - reduceGeminiChunk(state, chunk): text appends, a functionCall REPLACES (last wins, unlike OpenAI's concatenation) -- byte-identical to the inline loop. - finalizeGeminiToolId(toolId, uuidGen): the empty-id -> generated-id fallback. Tested: OpenAI missing-choice/empty, content-no-tools, one tool_call, nullish-coerce, first-only; Gemini text-append, functionCall-capture, last-wins replacement, undefined args -> "{}", no-op chunk; and the id fallback. tsgo 0; 729 tests.

Its meaningful scenarios are ALREADY covered by REAL tests in applyEngineV2.test.ts with a concrete MockRollbackSnapshotService: "on apply failure, snapshot restore is called" by the atomicity test (:237, asserts createdCount/restoredIds/no-discard) and "success path discards snapshot" by the snapshot-lifecycle test (:295). The third placeholder ("snapshot skipped -> git restore invoked") asserted nothing, so deleting loses no coverage. Removing fake tests (false confidence) serves the no-fake-safety goal.

The ~680-line capability-scoring arithmetic that decides which model Auto picks lived in the private ModelRouter.scoreModel and was untestable. Extracted it VERBATIM into a pure, node-tested common/routing/computeModelScore.ts; ModelRouter.scoreModel is now a thin wrapper that resolves the impure inputs (getCachedCapabilities, realParamSize from settingsState, this.isVisionCapable, the freeTierQuotaService lookup, the two globalSettings reads) and delegates. Proven byte-identical to git HEAD: a whitespace-normalized diff of the extracted scoring body against HEAD's scoreModel yields ZERO content differences modulo the 5 documented input substitutions (the injected capabilities/realParamSize/isVisionCapable/getFreeTierRemaining + routingPolicy/localFirstAI scalars, and 3 em-dash->'--' hygiene edits). A 4-lens adversarial-verify Workflow independently re-derived this (all lenses: byte-identical; blast-radius clean; oracle is a true independent copy). Validation: 50k differential fuzz vs a GENERATED oracle (test/common/computeModelScore.oracle.ts = HEAD's scoreModel body, script-extracted with the same substitutions -> catches any future drift of the extracted fn from the original) + 11 hand-traced goldens pinning each scoring axis (quality tier, privacy, code/codebase-question, local-first heavy/light, low-latency, vision, free-tier exhaustion) + invariants (auto->0, score>=0, quota-throw swallowed). Removed now-unused imports from modelRouter. tsgo 0; common suite 798 -> 814 (+16); hygiene clean (0 non-ASCII on added src lines).

A successful mid-task model escalation (tryEscalateModel) hands the SAME task to a fresh, more capable model, which must start with a clean per-attempt budget. The iteration-cap escalation site (chatThreadService ~3552) reset BOTH nMessagesSent and consecutiveToolErrors, but the two tool-error escalation sites (~4747 unparseable, ~4865 failed-tool-calls) reset only consecutiveToolErrors -- so a tool-error-escalated model silently INHERITED a spent iteration budget and could hit the iteration cap and stop before it had a fair chance to finish (e.g. a weak local model that burned 25/30 steps then failed tool calls would hand the strong cloud model only 5 steps). The total work stays bounded by the unchanged global escalationCount cap (MAX_MODEL_ESCALATIONS), exactly as the iter-cap site already accepted. Fix: centralize the reset in pure common/agentLoopDecisions.ts computePostEscalationCounters(triggerSite) (section 2, escalation owner) -> {nMessagesSent:0, consecutiveToolErrors:0} uniformly; route all three reset sites through it. Golden table pins the contract that every trigger site resets BOTH counters and that the two sites agree (regression guard against the old non-uniformity). The global escalation budget is intentionally NOT reset (it bounds total cross-model work). The llmError escalation path (resets its own nAttempts) is a different loop and out of scope. tsgo 0; common suite 814 -> 817 (+3). The chatThreadService wiring is browser-layer (not node-testable); the reset logic + its uniformity are node-tested in the pure fn, and the wiring is type-checked.

The write side (serializeEvents/shouldRotate/rotatedLogPath) already lives in pure common/auditLogFormat.ts; the inverse was missing. Added parseJsonl(content) -> { events, skipped }: one JSON object per line, blank/whitespace-only lines ignored (serializeEvents always trails a newline), and a non-blank line that fails JSON.parse is SKIPPED + counted rather than thrown. The audit log is append-only and can be cut mid-write by a crash, so a single truncated trailing line must NOT lose the whole tamper-evident record -- every well-formed line before the corruption is still recovered. This is the read-side building block the deferred audit-view/export will consume (the file read itself stays in AuditLogService); it also pins the serialize<->parse round-trip bidirectionally. Tests: golden round-trips, a truncated trailing line (skipped=1, prior events survive), a corrupt MIDDLE line (later valid lines still parse), blank/whitespace tolerance, empty content. The pre-existing round-trip test now delegates to parseJsonl instead of a hand-rolled split/JSON.parse. tsgo 0; common suite 817 -> 822 (+5); hygiene clean.

Models without native function-calling (every local model in practice) rely on it, so it is load-bearing for agentic use -- and it lived in electron-main, untested. Extracted the state machine + its 4 private helpers (findPartiallyWrittenToolTagAtEnd, findIndexOfAny, parseXMLPrefixToToolCall, trimBeforeAndAfterNewLines, ToolOfToolName) VERBATIM into pure node-tested common/xmlToolCallScanner.ts as createXmlToolCallScanner(tools, toolId) -> { push(accumulatedFullText), trimAndGetFinal() }. extractXMLToolsWrapper is now a thin adapter keeping the onText/onFinalMessage plumbing + tool-set resolution (availableTools) and delegating; toolId is injected (generateUuid) so the scanner is deterministic. Removed the now-unused imports (SurroundingsRemover/RawToolCallObj/ RawToolParamsObj/ToolName/ToolParamName); extractReasoningWrapper is untouched. Behavior-preserving: the 4 helpers + push body are byte-identical to git HEAD (the only deltas are the param rename params.fullText->accumulatedFullText, the trailing onText({...}) replaced by a return the adapter re-adds, and two dropped commented-out console.logs). A 4-lens adversarial-verify Workflow confirmed byte-identical via THREE independent differential fuzzes that drove HEAD's verbatim wrapper vs the compiled scanner+adapter over random inputs x random chunkings (60k + 23k + 6.7k cases, 0 mismatches), including the first-tag-by-tool-order latching quirk and the onFinalMessage double-call timing. The one real finding it surfaced (a test-soundness gap: only finalized displayText was asserted, never an intermediate push() return -- which is what onText forwards live) is fixed by a mid-stream displayText test that catches mid-stream markup-hiding regressions (e.g. dropping the partial-tag buffer). Tests: complete calls, fragment splits, char-by-char convergence, monotonic growth, 9 malformed inputs (never throw, one-shot + fragmented), JSON-blob passthrough, unknown-tag passthrough, first-tag latching. tsgo 0; common suite 833 -> 855 (+22); hygiene clean.

Used by the FIM, Ollama-FIM, and Ollama-chat paths. Extracted computeMaxTokensForLocalProvider VERBATIM to pure node-tested common/localProviderMaxTokens.ts; the 3 call sites now import it. The surrounding SDK/streaming/abort plumbing stays in electron-main (only CDP-testable). Golden table pins every branch: cloud->300 regardless of feature, local Autocomplete->96, local Ctrl+K/Apply->200, local Chat/SCM/unknown/undefined->300. tsgo 0; common suite 855 -> 859 (+4); hygiene clean.

It drives local-provider optimizations (shorter timeouts, streaming FIM, the local max-tokens budget) and -- importantly -- matches by HOSTNAME not substring, so "localhost.evil.com" is correctly NOT local. That subtlety deserves one tested home, not four copies a fix could miss. Extracted isLoopbackEndpoint(endpoint) to pure node-tested common/loopbackEndpoint.ts (verbatim loopback set localhost/127.0.0.1/0.0.0.0/::1, same URL parse + try/catch -> non-local on missing/empty/unparseable). Each of the 4 sites collapses to `(providerName === 'openAICompatible' || providerName === 'liteLLM') && isLoopbackEndpoint(settingsOfProvider[providerName]?.endpoint)` -- byte-identical (false unless the guard holds AND the endpoint is loopback). The explicit-provider list and the FIM site's hasFIMSupport use are unchanged. Not a security boundary (egress stays gated by egressPolicy); this is a UX/responsiveness gate. Tests pin the common local cases, case-insensitivity, the hostname-not-substring guard (localhost.evil.com -> false, LAN -> false), and the safe non-local default. tsgo 0; common suite 859 -> 863 (+4); hygiene clean.

Two services re-exported an interface/type as a VALUE, which the TS compiler elides but the esbuild dev-transpile (node build/next/index.ts) cannot, so the emitted out/ module had no such runtime export and the workbench threw at module load: "The requested module './editRiskScore.js' does not provide an export named 'EditContext'" - editRiskScoringService.ts:18 `export { EditContext, EditRiskScore }` (both are interfaces) -> `export type { EditContext, EditRiskScore }` - ollamaInstallerService.ts:13 `export { MODEL_PACKS, ModelPackKey }` (ModelPackKey is a type alias) -> `export { MODEL_PACKS, type ModelPackKey }` These are dev-build-only breakages (the production gulp/tsc build elides type re-exports correctly), but they made the cortexide UI fail to load under the esbuild dev transpile that the smoke harness uses. Swept the whole cortexide tree for other bare re-exports; the only other ones (imageQA/index.ts) already use the inline `type` modifier. tsgo 0; LIVE-verified: re-transpile + relaunch -> the module-load SyntaxErrors are gone and cdp-smoke is 11/11 (was failing "no fatal console errors").

So RAG was BM25-only and the cortexide.index.ast config did nothing. Rewired it to delegate WASM loading to the editor's own ITreeSitterLibraryService (the same service the terminal command parser uses) -- getParserClass() (owns Parser.init), getLanguagePromise(grammarId) (owns Language.load + wasm-path resolution, and bypasses the editor's prefer-treesitter support gate), then `new Parser(); parser.setLanguage(language); parser.parse(content)`. Parsers are cached per grammar (a missing/failed grammar caches null so it is not retried per file), and Tree objects are released via tree.delete() in a finally (they hold WASM memory; the extracted ASTSymbol[] is plain data). The existing AST traversal (_traverseAST etc.) was already correct standard web-tree-sitter API -- it just never received a real tree. Added pure node-tested treeSitterGrammarId(languageId) mapping our language ids to the shipped @vscode/tree-sitter-wasm grammar ids: identity for ts/tsx/js/python/java/go/rust/cpp/php/ruby, csharp -> 'c-sharp' (the on-disk grammar name), and c/swift/kotlin -> null (no grammar ships -> graceful BM25/LSP fallback, no throw).

The audit log records every dangerous action but there was no way to inspect it. Added: - IAuditLogService.readEvents() (flushes buffered writes, reads the file, parseJsonl -> {events, skipped}, tolerant of a truncated trailing line) + getLogPath(). - Pure node-tested formatAuditEvents(events, skipped) -> a readable, copy-able report (ISO timestamps from each event's epoch-ms ts, OK/ERR status, action, and only the present optional fields; header surfaces any skipped corrupt lines). - A "CortexIDE: Show Audit Log" Action2 that opens the rendered log in an editor (so it can be saved/exported); shows an info notice when auditing is disabled. LIVE-VERIFIED against the running dev build (audit enabled, a seeded audit.jsonl with 3 events + 1 truncated trailing line): the command opened an editor reading "CortexIDE Audit Log -- 3 events / (1 corrupt/truncated line skipped)" with each event rendered (prompt+model, apply+files+diffstats+latency, rollback ERR) -- proving readEvents -> parseJsonl -> formatAuditEvents -> editor end to end. +5 formatter tests; updated the MockAuditLogService stub for the 2 new interface methods. NOTE on the OTHER half of this item (wrap the global ILogService in RedactingLogService): deliberately NOT done. ILogService is constructed in desktop.main.ts BEFORE IConfigurationService exists, but the redaction service is config-dependent, so it cannot wrap the root logger cleanly there; and secret-bearing logs (LLM dispatch) are already redacted at the source (sendLLMMessageService) -- matching the project's prior high-risk/low-value assessment. There is no scoped cortexide logger to wrap instead. Left as an honest defer. tsgo 0; common suite 867 -> 872 (+5); cdp-verified; hygiene clean.

During a streaming SEARCH/REPLACE edit, each new block is located in the ORIGINAL file; if it can't be located (a 'Not found'/'Not unique' error) or its target range OVERLAPS a block already applied this stream, the WHOLE edit is reverted and the model is re-prompted from the first block. A wrong overlap test risks silent data loss (a good edit thrown away, or a conflicting edit applied), but the logic was inline in editCodeService and untested. Extracted the DECISION (not the side effects) to pure node-tested common/editStreamRevertDecision.ts: rangesOverlap(a,b) (touching endpoints count as overlap, matching the inline rule) + decideStreamRevert ({originalBoundsError, thisBlockRange, existingRanges}) -> {revert, errorMessage}. Byte-identical to the old `if (typeof originalBounds === 'string' || hasOverlap)` check incl. the 'Has overlap' message and error-takes-precedence ordering. The revert side effects (delete tracking zones, rewrite the file to the original, abort the stream) stay inline. Re-narrowed originalBounds with an unreachable `if (typeof originalBounds === 'string') return` after the revert guard (the old condition's `typeof === 'string'` provided the narrowing the pure call drops; decideStreamRevert reverts for every string, so the guard never fires). Tests: overlap (disjoint/touching/contained/identical/partial/gap), locate-error precedence, 'Has overlap', no-revert, first-block, some-semantics across existing ranges. tsgo 0; common suite 872 -> 881 (+9); hygiene clean.

Added a local Ollama embedding provider so semantic (BM25 + vector) retrieval activates when the user configures a model. Wiring (the renderer can't reach Ollama, so embeds route through electron-main, mirroring the LLM path): - electron-main sendOllamaEmbed (ollama SDK .embed) -> a new request-response 'ollamaEmbed' command on LLMMessageChannel, egress-gated defense-in-depth (refuses a non-loopback endpoint under local-only). - renderer LLMMessageService.ollamaEmbed (same loopback egress gate as ollamaList) returns the vectors. - OllamaEmbeddingProviderContribution (WorkbenchPhase.AfterRestored): when cortexide.rag.embeddingModel is set AND dispatchable, PROBES the model (so isEnabled() never lies), then registers an IAiEmbeddingVectorProvider; re-syncs on config / privacy-state change; unregisters when ineligible. - New cortexide.rag.embeddingModel setting (default '' = BM25-only; opt-in). - Pure node-tested common/ollamaEmbeddings.ts: extractEmbeddingVectors (throws on empty/ragged/non-finite so cosine similarity never gets garbage) + canUseOllamaEmbeddings eligibility. Privacy: Ollama is loopback, so chunks stay on-machine and the call is allowed under local-only (secrets are already redacted before embedding upstream). Any failure (no model / Ollama down) leaves retrieval gracefully on BM25. LIVE-VERIFIED against the running dev build (cortexide.rag.embeddingModel=nomic-embed-text, model pulled): the contribution logged "registered local embedding provider 'nomic-embed-text' -- hybrid retrieval active"; IAiEmbeddingVectorService.isEnabled()=true; getEmbeddingVector returned a real 768-dim vector; the electron-main round-trip returned 2x768 vectors. tsgo 0; common suite 881 -> 888 (+7); cdp-smoke 11/11; hygiene clean.

Results: -- **Gate A (gather read-only) — PROVEN end-to-end.** `test/cortexide-smoke/gather-isolated-e2e.mjs` - (fresh profile, GATHER only, no agent follow-up): the 7B emitted a real `` tool call, - and even after **Approve & Execute** (plan executed), `pwned.txt` was **never written to disk**. - The dispatch gate blocks real model-emitted writes in gather mode. - - Earlier alarming `pwned.txt`-on-disk was **agent-mode contamination** (a reused conversation - switched gather→agent; the agent phase, where writes ARE allowed, created it). Lesson: never - reuse a chat conversation across mode switches in a safety test. -- **Gate E (settings) / config + secure defaults — PROVEN live.** `phase1-safety-verify.mjs` 26/26 - (real modules decide correctly in-renderer; keys registered; vectorStore='none', secretDetect redact). -- **Gate D (workspace trust) — logic+wiring+trusted-path verified; untrusted-block NOT live-exercised.** - The dev CLI launch **auto-trusts** the workspace (no Restricted Mode even with `CX_KEEP_TRUST=1` + - seeded `security.workspace.trust.*`). Same dispatch chokepoint as the proven gather gate. -- **Gates B/C (terminal danger / cwd) — logic+wiring verified (26/26 + artifact); not driven live** - (would need the model to emit specific terminal commands + I won't run destructive commands). -- App boots on the branch (cdp-smoke 11/11). Capable agent writes work (diagtest.txt created by 7B in - agent mode). `launch-dev.sh` gains `CX_KEEP_TRUST=1`. - -### Phase 1 #1 — agent-path atomic writes ✅ DONE (2026-06-10) - -The agent edit path (`editCodeService → cortexideModelService.saveModel → textFileService.save`) -is now atomic.

(applyEngineV2 was already atomic.) - -### Phase 1 #2 — durable checkpoint/rollback ✅ DONE + LIVE-VALIDATED (2026-06-10) - -Edit restore now PERSISTS to disk (editCodeService awaits atomic `saveModel`). New pure -`common/agentFileOps.ts` (12 unit tests) = durable per-op rollback: recreate deleted (with prior -content), remove created, restore modified; atomic writes; failures surfaced; sequential edits undo -in reverse. `chatThreadService` journals the BEFORE-state of create/delete/edit/rewrite/multi_edit at -the dispatch chokepoint and replays them on disk on a checkpoint jump (+notify on incomplete). -tsgo 0; subset **263/0**. LIVE E2E (real 7B agent): create→rollback REMOVES; delete→rollback RECREATES -with original content; edit V1→V2→rollback restores V1 ON DISK. (Lesson: a checkpoint jump no-ops -while the agent is running — wait for idle.) Documented limitations: session-scoped journal (not across -app restart); deleted-folder contents not restored; redo doesn't re-apply create/delete. - -### Phase 1 — FUNCTIONALLY COMPLETE -All 6 items implemented, unit-tested (**263 passing, 0 failing**), tsgo 0 errors, and the -safety-critical behaviours live-validated end-to-end: -- #1 atomic writes ✅ (applyEngineV2 + agent-path saveModel; live: edit persists, no temp leak) -- #2 durable rollback ✅ (create/delete/edit restore on disk — live) -- #3 gather read-only at dispatch ✅ (live: blocks a real model-emitted write) -- #4 terminal danger-block + cwd containment ✅ (logic+wiring+renderer-tested; not driven with real destructive commands) -- #5 secret redaction before LLM ✅ (verified secure-by-default, live config) -- #6 workspace trust ✅ (logic+wiring+trusted-path live; untrusted-block NOT live — dev launch auto-trusts) - -Honest residuals: gate D untrusted-block and gates B/C with real destructive commands are not -*driven* live (dev auto-trust; won't run `rm -rf`), but they share the dispatch chokepoint that IS -live-proven via the gather gate, and their decision logic is renderer-tested (26/26). - -### Phase 2 — testable agent runtime (IN PROGRESS) - -Step 1 done (zero-risk): the agent loop's pure DECISION logic is extracted into -`common/agentLoopDecisions.ts` (5 pure fns: tool-error counter, escalation trigger, loop -continuation, completion routing, compaction/overflow) with **57 unit tests** — mirroring the -inline loop behavior byte-for-byte (two known latent bugs B1/B2 preserved + pinned). NO wiring yet, -so zero runtime risk. Design came from a 7-agent mapping workflow (`.claude/phase2-map-workflow.js`) -that verified every line/constant against source. tsgo 0; subset **263 -> 320 passing, 0 failing**. - -Remaining Phase 2 (separate behavior-preserving + live-validated commits): rewire the loop to -delegate to these (Edit A tool-error cap, then compaction, then iter-cap; defer the parse-classifier -+ llmError-gate to their own PRs), then the larger module split (AgentLoopController / ToolCallParser -/ AgentPlanner / etc.) per the user's Phase 2 spec. - -### Phase 2 — wiring Edits A/D/B LANDED + live-validated (2026-06-10) - -Step 2 done: the agent loop now DELEGATES to the pure decision fns (the tested module is the code -that runs, not a parallel copy that can drift). Three behavior-preserving commits, each tsgo 0 + -subset 320/0: -- **Edit A** (`db1bbdb0abd`) tool-error cap -> `updateConsecutiveToolErrors` with - `escalationAvailable:false` (keeps `consecutiveToolErrors` at the incremented value so the - escalate-reason + halt-message strings stay byte-identical, em-dash included; `tryEscalateModel` - stays authoritative). -- **Edit D** (`53f6a12d0c0`) compaction + overflow -> `computeCompactionOverflowDecision`; de-dupes - the two dynamic `getModelCapabilities` imports into ONE `contextWindow` resolution gated by a - `capsResolved` flag (closes the only divergence: the unreachable import-throw path). IMPROVEMENT - over the plan: split into a pre-compaction `compactDecision` and a post-compaction - `overflowDecision` so the warning reflects post-compaction `promptTokens` (a single pre-compaction - call would have spuriously warned after a successful compaction). -- **Edit B** (`cac44f0039a`) iter-cap escalation gate -> `shouldEscalateModel('iterCap')`; - short-circuit is provably equivalent to the original unconditional await (tryEscalateModel returns - false at its own guard with no side effect). `isAutoMode` is out of scope here (TDZ) and ignored by - the iterCap branch, so it is passed as a literal `false`. - -**Adversarial verification (6-agent Workflow, `.../phase2-wiring-adversarial-review`):** all 6 -reviewers (per-edit control-flow/strings/tokens/scope + a whole-diff integration critic) returned -behaviorPreserving=TRUE, **zero reachable divergences**. One reviewer ran an exhaustive 9,216-combo -enumeration of the compaction/overflow inputs (0 divergences in {shouldCompact, warn, pct}); strings -verified byte-identical incl. the U+2014 em-dash; B1/B2 latent behaviors confirmed preserved. The two -flagged non-issues were a non-observable microtask/await-timing change (Edit B short-circuit) and the -redundant `overflowPct != null` guard. - -**Live validation (CDP, post-wiring build, fresh ws):** -- boot smoke `cdp-smoke.mjs` 11/11. -- HAPPY PATH: `atomic-edit-e2e.mjs` with `qwen2.5-coder:7b` in Agent mode rewrote target.txt - correctly (marker present, not empty, no .vsctmp leak) -> loop continuation + Edit A success-reset - + per-iteration Edit D/B checks all intact end-to-end. -- CAP/ESCALATION PATH: new `phase2-cap-escalation-probe.mjs` with `qwen2.5-coder:1.5b` (thrashes on a - multi-step Flask task) -> the wired cap path triggered `tryEscalateModel` live ("Switched to ..." - detected) -> the escalation wiring fires under real model thrash. (The toast does not distinguish - tool-error-cap vs iter-cap as the trigger, but a wired path fired.) - -Tests: cortexide common node subset **320 passing, 0 failing**; tsgo 0 errors throughout. - -Deferred (own reviewed PRs, per the plan): Edit C (llmError escalation gate, `nextModel`-scope -sensitive), Edit E (completion routing collapse), and the parse-classifier (function #6, -classifyToolCallFromLLMResponse). Then the larger module split (AgentLoopController / ToolCallParser -/ ToolPermissionEngine / AgentPlanner / ModelSelectionEngine / AgentContextBuilder / AgentSessionStore -/ AgentVerifier). - -### Phase 2 — Edit E investigated + DEFERRED; first module-split (ToolCallParser core) LANDED (2026-06-10) - -**Edit E (completion-routing collapse) was mapped and DEFERRED as not worth doing now.** A 4-agent -mapping workflow (`.../phase2-editE-routing-map`) produced a full terminus table of the LLM-turn block -and concluded: the genuinely valuable full-collapse (Option A) is UNSAFE because the -`interrupted`/`completionSignaled` returns sit BEFORE the consecutive-tool-error cap + plan-step -bookkeeping while the `await`/`continue` decision sits AFTER -- collapsing them into one -`classifyCompletionState` switch would reorder side effects. The safe minimal wiring (Option B) only -wraps the trivial `awaitingUserApproval ? await : continue` + the two skip flags in verbose pure-fn -calls (all other inputs hard-coded false) -- low value, added verbosity, no reliability/testability -gain. So `classifyCompletionState` (and `decideLoopContinuation`, which overlaps what A/B already -wired) stay UNWIRED by choice; they remain tested. Conclusion: the cleanly-wireable pure decisions are -all wired (A/D/B); the remaining two model routing the real loop cannot cleanly separate. - -**First module-split increment LANDED** (`a99767686cd`): extracted the agent loop's text-fallback -tool-call recognition into pure `common/toolCallRecognition.ts` (`recognizeTextToolCall`) and removed -the single-use private `_parseJSONToolCallFromText`. This is the safe core of the deferred -parse-classifier (ToolCallParser) and centralizes + TESTS the previously-untested preamble/marker-cut -logic that strips a model's hallucinated multi-tool transcript (the #1 weak/local-model robustness -hazard). Behavior-preserving (mirrors the inline block byte-for-byte: same parseTextToolCall, same -4-marker cut, same cutIdx>0/===0/===-1 preamble ternary, same toolCall build). The latent bug B1 -(unparseable would-be tool call silently treated as natural text) is PRESERVED; its deliberate fix -belongs in this module in a later tested change (documented in the module header). Verification: tsgo 0; -new `test/common/toolCallRecognition.test.ts` (10 cases) -> subset **320 -> 330 passing, 0 failing**; -adversarial review (21-input equivalence fuzz) byte-identical; LIVE cdp-smoke 11/11 + atomic-edit-e2e -with `qwen2.5-coder:7b` (which emits the tool call as TEXT) recognized + executed -> file rewritten. - -**Second module-split increment LANDED** (`7c548eb9a95`): extracted the agent loop's "should I -SYNTHESIZE a tool call from the model's prose?" GATE into pure `common/toolSynthesisDecision.ts` -(`decideToolSynthesis`); the synthesis ACTION stays inline. This finally TESTS the heuristic that most -governs weak/local-model agentic behavior (when a chatty reply auto-converts to an action): the -action/codebase/web intent word lists, the already-emitted-tool-tag suppression, the `looksFinal` -closer regex, the image-analysis carve-out, and the nAttempts/alreadyActed/file-cap gating. It is also -the synthesis machinery that is B1's runtime vector, now isolated + pinned. Behavior-preserving -(mirrors the inline outer guard + inner condition byte-for-byte; caller coerces -hasToolCall/hasImages/hasSynthesizedForRequest with `!!`, which the original used only in truthy/`!` -contexts). NOTE: a first attempt landed on the WRONG `const userRequest` (there are 3: normal-mode, -synthesis, needsMoreSearch) and clobbered the normal-mode advisory; caught immediately, reverted via -`git checkout`, and redone anchored on the synthesis outer-`if`. Verification: tsgo 0; new -`test/common/toolSynthesisDecision.test.ts` (20 cases) -> subset **330 -> 350 passing, 0 failing**; -adversarial review with a 500k-input equivalence fuzz (inline gate vs module) 0 divergences; LIVE -cdp-smoke 11/11 + atomic-edit-e2e (7B) completes (extraction did not break the loop). Still inline (own -follow-ups): the native-call canonicalization (~4439, already pure 1-liner) and the `needsMoreSearch` -"how many X" gate (~4676). - -**Third module-split increment LANDED** (`5a3da8388c7`): extracted the agent loop's SECOND synthesis -trigger -- the `needsMoreSearch` "how many X" follow-up-search gate (~4620-4645) -- into pure -`common/toolSynthesisDecision.decideHowManySearch`. With `recognizeTextToolCall` + -`decideToolSynthesis` + `decideHowManySearch`, the tool-call recognition / synthesis-decision surface -(the parse-classifier / **ToolCallParser is now functionally COMPLETE**) is fully extracted + tested; -only the trivial already-pure native-call canonicalization one-liner remains inline by design. -Behavior-preserving (HOW_MANY_NOUNS 12 / COUNT_IN_RESPONSE_TERMS 9 match the inline arrays exactly and -correctly differ; `.some(includes)` == the `||` chains; outer guard is the De Morgan dual; inner -AND-chain verbatim; `!!` coercions safe). Verification: tsgo 0; `toolSynthesisDecision.test.ts` +13 -(33 total) -> subset **350 -> 363 passing, 0 failing**; adversarial review with a 2,000,000-case -differential fuzz: 0 mismatches; LIVE cdp-smoke 11/11 + atomic-edit-e2e (7B) completes. - -**Fourth module-split increment LANDED -- ModelSelectionEngine** (`520da9299c9`): extracted the two -remaining inline, untested pieces of model selection into pure `common/modelSelectionEngine.ts` (the -failover RANKING was already pure+tested in `routing/modelFailover.pickNextFailoverModel`): -`resolveModelRuntimeCaps` (the local-vs-cloud loop-cap POLICY -- local models get the tighter 30/3 caps; -replaces `recomputeModelState`'s cap logic) and `buildFailoverCandidates` (turns providers/models into -`FailoverCandidate[]` with the eligibility rules: skip unconfigured/hidden/tried, a LOCAL model never -reports native tool calls, coder = name||FIM; replaces `_pickNextUntriedModel`'s gather loop -- the -caller still flattens settings + supplies a getCaps wrapper, and pickNextFailoverModel/toModelSelection -are unchanged). Drops the now-unused chatThreadService imports (isLikelyCoderModelName / -KNOWN_CAPABLE_AGENTIC_PROVIDERS / FailoverCandidate type / freeTierIdOfProviderName; localProviderNames -stays). Behavior-preserving (byte-for-byte; candidate order preserved). Verification: tsgo 0; new -`test/common/modelSelectionEngine.test.ts` (15 cases) -> subset **363 -> 378 passing, 0 failing**; -adversarial 8000-run differential fuzz 0 mismatches; LIVE cdp-smoke 11/11 + atomic-edit-e2e (7B) -completes (resolveModelRuntimeCaps drives every turn). buildFailoverCandidates is byte-identical to the -escalation path proven live earlier (the cap-escalation probe), so not separately re-driven. - -**Phase 2 module-split status:** the agent loop's PURE decision/selection surface is now extracted + -tested across `agentLoopDecisions` (caps/escalation/compaction; A/D/B wired), `toolCallRecognition`, -`toolSynthesisDecision` (2 fns), and `modelSelectionEngine` (2 fns). What remains is genuinely -stateful orchestration: the **AgentLoopController** (the `while` loop itself + tryEscalateModel's async -side effects), **AgentContextBuilder** (message prep + the prep cache), **AgentSessionStore** (thread -persistence), **AgentVerifier**, **AgentPlanner**. These are class/state refactors, not pure-fn -extractions; AgentLoopController is the keystone. - -### Phase 2 — B1 FIXED: unparseable tool-call attempt is now an agent error (2026-06-10, FIRST behavior change) - -`028e3a16ca7` -- the first DELIBERATE behavior change of the Phase 2 work (all prior commits were -behavior-preserving). A 4-agent investigation established B1's REAL manifestation (the old "exhausts the -iteration cap" comment was WRONG): a model that emits structured tool-call markup which fails to parse -(`{broken`) had the malformed text committed as its FINAL answer and the loop -exited via terminate_natural -- the agent appeared done but did nothing, recording no error -(**silent-no-op-success**). Fix: `recognizeTextToolCall` now reports `attemptedButMalformed` (+ exported -`hasStructuredToolCallMarker`) -- conservative detection (only the `` EXCLUDED to avoid JSX/XML collisions; bare `{` not a marker; -markers QUOTED in code fences/backticks ignored). The loop now counts such an attempt toward the SAME -consecutive-tool-error cap and re-prompts (corrective feedback as a USER turn, to preserve -Anthropic/Gemini alternation); at the cap it escalates or stops honestly. Bounded (counter rises to the -cap; iteration cap is a backstop), no double-count (mutually exclusive with the post-dispatch counter), -resets on a later real tool success. Verification: tsgo 0; subset **378 -> 388 passing, 0 failing**; -adversarial review (correctness-focused) -- it surfaced 2 real issues (false positives on quoted/JSX -markers; consecutive-assistant alternation) which were FIXED (wrapper-only + code-strip detection; user -re-prompt turn). LIVE: cdp-smoke 11/11 + atomic-edit-e2e (7B) still completes -> the branch does NOT -false-fire on the normal path (the key regression check). New `b1-malformed-toolcall-probe.mjs` attempts -the positive firing path but is INCONCLUSIVE (the 7B won't emit malformed markup on demand -- capable -models round-trip it); the firing path is unit-tested + reviewed and reuses the cap/escalation machinery -proven live earlier. RESIDUAL: live-firing not driven (needs a model that emits malformed markup or a -synthetic-response test hook). - -### Phase 3 — Model-agnostic provider platform (STARTED 2026-06-10) - -First increment (`b6773313bee`): the 18-provider dispatch -(`electron-main/llmMessage/sendLLMMessage.impl.ts`, 0 tests -- the node runner excludes electron-main -since it imports the Anthropic/OpenAI/Gemini/Ollama SDKs) now has its PURE, SDK-free tool-call-capture + -message-format helpers extracted into node-tested `common/providerToolFormat.ts`: `buildRawToolCallObj` -(shared core), `rawToolCallObjOfParamsStr` (OpenAI-compat streaming-args JSON -> our tool format), and -`sanitizeOpenAIMessagesForEmptyContent` (the Vertex/Pollinations non-empty-content quirk). These govern -correctness across the OpenAI-compatible family (openAI/groq/deepSeek/mistral/openRouter/xAI) + -Anthropic (`rawToolCallObjOfAnthropicParams` keeps its SDK param type but delegates to the shared core). -Behavior-preserving (bodies copied byte-for-byte; adversarial byte-identity review passed). tsgo 0; new -`test/common/providerToolFormat.test.ts` (17 cases) -> subset **388 -> 405 passing, 0 failing**. LIVE: -cdp-smoke 11/11 + atomic-edit-e2e (7B) -> `sendOllamaChat` exercises the extracted sanitizer and the -edit completes (live-validated on the ollama path). REMAINING Phase 3: the SDK-typed tool-schema -builders (toAnthropicTool/toGeminiFunctionDecl/openAITools) + the per-provider request/response paths -need SDK-type extraction or a mock-fetch harness to test; per-model capability registry; llama3.x -fallback ordering; provider tool-format fixes; model-health UI; first-class OpenAI-compatible config; -native Bedrock (or label proxy-only). - -Second increment (`bdd8d94e6cc`): a 4-agent audit (`.../phase3-capability-provider-audit` workflow) -found multiple real bugs in the 0-test `common/modelCapabilities.ts` registry. Added the registry test -suite (`test/common/modelCapabilities.test.ts`, 9 cases pinning the resolution contract + -unrecognized-defaults + override precedence) and FIXED the two highest-severity bugs: (1) **mixed-case -exact-match** (`modelOptions[modelName]` -> `modelOptions[modelName_]`; 'GPT-4o' used to return a -capability-less object / forced XML tool mode; common same-case path byte-identical); (2) **deepseek -reasoning inverted** (deepseek-chat/V3 advertised reasoning, deepseek-reasoner/R1 didn't; swapped the -spread bases, which differ only in reasoningCapabilities). tsgo 0; subset **405 -> 414 passing**; -adversarial high-blast-radius review = both correct/safe; LIVE 11/11 + 7B atomic-edit (registry resolves -ollama caps every turn). - -Third increment (`894c7a2c42b`): FIXED the **3 last-match-wins `modelOptionsFallback` orderings** -(anthropic/openAI/xAI) -> first-match-wins (`ret(k)` + return-early). The review found this was -collapsing nearly EVERY dated variant to its broad parent (gpt-5-mini-2025->gpt-5, o3-mini->o3, -claude-opus-4-8-latest->legacy 4.0, grok-4-0709->grok-3). Required moving openAI's gpt-3.5 above the -broad gpt-5 and tightening the broad gpt-5/gpt-5.1/gpt-4.1 to precise `includes('gpt-N')` (the old -`gpt && '5'` matched a date's stray '5' -> a regression the new tests CAUGHT). tsgo 0; subset -**414 -> 418 passing** (+4 tests); adversarial old-vs-new differential (battery from out/) = -correct/safe; LIVE 11/11 + 7B atomic-edit (no agent-flow regression). - -Fourth/fifth increments cleared the rest of the audit backlog: -- `ff1718a708d` -- extracted `toOpenAICompatibleTool` to `common/providerToolFormat.ts` (node-testable) - and FIXED it to emit `paramsWithType` (OpenAI-family tool schemas now ship typed params). +3 tests. -- `31a8820143a` -- fixed the `extensiveModelOptionsFallback` llama shadowing (most-specific-first; - 'llama-3.1-8b' -> llama3.1 not 10M-ctx llama4-scout; 'maverick' -> llama4-maverick; llama3.1/3.2/3.3 - reachable). +4 tests. - -**PROVIDER/CAPABILITY AUDIT BACKLOG FULLY CLEARED** (6 confirmed bugs fixed across 3 commits: mixed-case -exact-match, deepseek reasoning inversion, 3 last-match-wins fallback orderings, OpenAI tool-builder -untyped params, llama shadowing). The registry went from 0 tests to a tested golden-table contract -(modelCapabilities.test.ts) + the provider tool-format helpers are node-tested -(providerToolFormat.test.ts). cortexide node subset now **425 passing, 0 failing**; tsgo 0. -Remaining Phase 3 (NOT bugs): SDK-typed tool-schema builders (toAnthropicTool / toGeminiFunctionDecl -- -need SDK-type extraction or a mock-fetch harness), per-provider request/response mock-fetch tests, -model-health UI, native Bedrock, first-class OpenAI-compatible config. - -Sixth increment (`8c6ccdf39be`): extracted the **OpenAI-compatible streaming accumulator** out of -`_sendOpenAICompatibleChat`'s stream loop (the highest-value untested provider logic) into a pure, -node-testable reducer `accumulateOpenAIChatDelta` in `common/providerToolFormat.ts`. This is the core -of tool-call CAPTURE for the whole OpenAI-compatible family (openAI / groq / deepSeek / mistral / -openRouter / xAI / openAICompatible / liteLLM / lmStudio / vLLM) and had **zero tests**. The reducer -mirrors the inline logic byte-for-byte: text append; Mistral's parts-array `content` split into text vs -reasoning; the single `index===0` tool call whose name/arguments/id are CONCATENATED across deltas (the -OpenAI streaming protocol delivers `function.arguments` in fragments); dedicated reasoning-field append -(`(... || '') + ''`). The ONE defensive divergence I first introduced (optional chaining on a -type-impossible null tool-array entry, which would have turned the original's throw into a skip) was -removed so the extraction is exactly byte-identical. Verification: tsgo 0; new accumulator suite +16 -(**425 -> 441 passing, 0 failing**) covering Mistral object-content, `index!=0` drop, no-index skip, -fragmented args, falsy-reasoning, purity (frozen input), and an end-to-end fragmented tool-call stream; -**500,000-case differential fuzz** (old inline ref vs the extracted reducer over random -content/tool_calls/reasoning deltas) = 0 mismatches; LIVE: cdp-smoke 11/11 + atomic-edit-e2e (7B) no -regression (the 7B agent loop uses `sendOllamaChat`, NOT this path), PLUS the reducer itself -live-validated against REAL ollama `/v1` (OpenAI-compatible) streaming chunks - the text path via -qwen2.5-coder (5 chunks -> "HELLO FROM STREAM") and the **structured `tool_calls` delta path via -llama3.2:3b** (1 tool delta -> `get_weather` / `{"city":"Tokyo"}` -> parsed `{city:"Tokyo"}`). NOTE: the -non-streaming path (`processNonStreamingResponse`, takes `toolCalls[0]`) and the Gemini/ollama/Anthropic -stream handlers were left untouched (different shapes); the trivial SDK-typed tool-schema builders -(toAnthropicTool/toGeminiFunctionDecl, ~15 lines each) are low-value and remain inline. A genuine -remaining Phase 3 item surfaced: the single-tool-call-per-turn limit is architecturally baked into the -`onFinalMessage({ ...toolCall })` contract (Gemini's `functionCalls[0]`, OpenAI's `index===0`); capturing -ALL tool calls per turn is a rippling change, deferred. - -Seventh increment (`8af32b383d8`): extracted the inline **Gemini rate-limit/quota error parsing** out -of `sendGeminiChat`'s catch into a pure node-testable `formatGeminiRateLimitError` in a new -`common/providerErrorFormat.ts` (a home for provider error-message formatters, a Phase 3 robustness -theme). The Gemini error message is often a JSON string that itself wraps another JSON string under -`error.message`, with the retry hint in a `google.rpc.RetryInfo` detail (`retryDelay "57s"/"57.6s"`); -this nested-parse + retry-delay minute/second formatting + pluralization was completely untested. -Byte-identical (best-effort `JSON.parse(whole)` then a regex-extracted `{...}` block; inner-error -unwrap; code/status quota fallback; minute/second formatting; generic catch-all on throw); the call -site still does `onError({ message: formatGeminiRateLimitError(error.message), fullError: error })`. -Verification: tsgo 0; new `providerErrorFormat.test.ts` +13 (**441 -> 454 passing, 0 failing**) over all -branches (nested+RetryInfo min/sec/whole-min/singular/plural/fractional-ceil, outer-only message, -code-429 / RESOURCE_EXHAUSTED fallback, embedded-JSON-in-noise, no-JSON default, malformed-brace throw -fallback, empty); **200,000-case differential fuzz** old-vs-new = 0 mismatches; cdp-smoke 11/11 (app -boots healthy with the main-process change). The Gemini error path is CLOUD-ONLY and cannot be driven -live locally (no Gemini key; cannot force a 429) - validated by unit tests + fuzz + differential review. - -### Phase 2 — AgentLoopController split BEGUN: first keystone-loop seam extracted (2026-06-11) - -`13d41aa9724` -- the FIRST extraction out of the keystone 1,800-line `_runChatAgent` loop -(chatThreadService.ts:3140-4927). A read-only 6-agent **map workflow** (`map-agentloop-controller`, -journal `map-agentloop-controller-wf_e1fc80c3-656.js`) sliced the loop into 5 regions and synthesized -the safest first seam: the **excessive-file-read guard** (4716-4753) is the only remaining seam that is -genuinely pure (4 scalar inputs, 4 outcomes), tiny, and has ZERO coupling to the mutable -plan/escalation state that makes every other seam "hard". Added `decideFileReadGate` to -`common/agentLoopDecisions.ts` (section 6): `{ hasToolCall, toolName, fileReadLimitExceeded, -filesReadInQuery, maxFilesReadPerQuery } -> { action: no_tool | skip_already_exceeded | hit_limit_now | -proceed, filesReadCount, nextFilesReadInQuery, nextFileReadLimitExceeded }`. The caller keeps every side -effect (limit message, the 'LLM' `_setStreamState`, `shouldSendAnotherMessage` + `continue`) and assigns -the two next-counter values back. The off-by-one (limit fires at `>= max`, the counter increments only -on the read_file proceed path, so the max-th read is BLOCKED not performed) is PRESERVED as-is and -pinned by a test (fixing it is a separate change). Verification: tsgo 0; +9 golden-table tests -(**454 -> 463 passing, 0 failing**); **1,800-combo exhaustive differential enum** old-vs-new = 0 -mismatches; **4-agent adversarial review** (control-flow / counters / side-effects + synthesis) = -behavior-preserving, 0 reachable divergences (the only flagged arm, `no_tool`, is unreachable at a call -site hardcoded to `hasToolCall:true`); LIVE cdp atomic-edit-e2e (7B) completes through the modified gate -with no false-fire. - -`b5d63643aae` -- second keystone-loop seam: lifted the **safety-critical rate-limit classifier** -(chatThreadService.ts:4172-4176) out of the llmError branch into a pure `isRateLimitErrorMessage` in -`common/providerErrorFormat.ts` (alongside formatGeminiRateLimitError). It drives the `avoidFreeTier` -failover decision and MUST match the service-layer rate-limit shapes (the keyword set includes Google's -quota/resource_exhausted, which the old 429-only check missed). Byte-identical (same case-insensitive -substring chain; the call site passes raw `error.message`, the fn lowercases it). `shouldEscalateModel` -already CONSUMES `isRateLimitError` as an input, so this extracts its producer to the same tested layer. -tsgo 0; +11 tests (**463 -> 474 passing, 0 failing**); **300,000-case differential fuzz** = 0 mismatches; -cdp-smoke 11/11 + atomic-edit-e2e (7B) no regression (classifier only fires on llmError; unit+fuzz cover -the path). NOTE on the backlog below: the top HIGH lead (llmError partial-tool-call loss at ~4400) was -RE-VERIFIED in code and DOWNGRADED - it's a UX-recovery gap (the error itself IS surfaced via -`_setStreamState({ error })`; no correctness/data issue) in the documented-fragile error/failover path, -so it's deferred (not worth destabilizing that path for partial-output UX). The escalation -`nMessagesSent`-reset inconsistency (~4807) was also re-verified and judged a defensible design choice -(the iter-cap site MUST reset; the tool-error site need not), not a clear bug - deferred. - -**AgentLoopController latent-bug backlog** (from the map; LEADS to re-verify in code, NOT yet fixed - -ranked by severity/fix-risk; line numbers approximate, the loop is ~3140-4927): -- HIGH: on an `llmError`, `streamState.llmInfo` is already cleared to `undefined` by the onError - handler, so reading `toolCallSoFar` (~4400) is always null and the `interrupted_streaming_tool` - message is never added -> partial streaming tool-call output silently lost on every streaming error. -- HIGH: `_generatePlanFromUserRequest` (~3325) is called with the raw (possibly 'auto') modelSelection - instead of `resolvedModelSelection` (confirm the callee doesn't re-resolve before fixing). -- HIGH (metrics-only): a recomputed `promptTokens` (~3931-3961) shadows the standardized - `_computeTokenCount` value handed to `chatLatencyAudit.markPromptAssemblyEnd` on the model-switch path. -- MED: tool-error-escalation path (~4807) does NOT reset `nMessagesSent` on a successful - `tryEscalateModel` (the iter-cap + outer-loop escalation sites DO) -> escalated model gets a - shorter-than-intended iteration budget. Inconsistent across the 3 escalation sites. -- MED: `modelSupportsTools` re-synthesis gate (~4473/4550) keys on `hasSynthesizedToolsInThisRequest` - which is only set true AFTER a synthesized tool both runs AND completes; an interrupted/failed - synthesis leaves it false -> possible re-synthesis loop. -- MED: pre-loop tool exec (~3431) destructures only `{ interrupted }` from `_runToolCall`; a tool that - ERRORED (not interrupted) still runs the success branch and may mark a failed step completed (the - main-loop path at ~4818 correctly inspects the tail tool-message type - the pre-loop path is the - inconsistent twin). -- MED: plan-step null-guard gaps (~3388, ~4858), in-place plan-cache divergence (~3358), compacted-view - cache miss (~3763). LOW: idle-interruptor promise never invokes its fn (~3232, likely dead); - awaiting_user exit leaves isRunning set with no checkpoint (~4889, likely intentional). -Next-safest pure-fn seams for the backlog (from the map): `isRateLimitError(msg)` (4172), auto-mode -predicate (3857), fallback-chain next-model picker (4215). HARD/deferred: AgentPlanStepTracker class -(4818-4876 + pre-loop twin 3431-3483) - do AFTER the pure gates + the 4763-vs-4819 desync + pre-loop -success-branch bug are fixed, so the refactor target is correct-by-construction. - -### Phase 5 — Apply engine / editing correctness STARTED (2026-06-11) - -`7cce1593d27` -- FIRST Phase 5 increment. Extracted the SR ORIGINAL-block matcher `findTextInCode` -(+ its `numLinesOfStr` / `removeWhitespaceExceptNewlines` helpers, used nowhere else) from the browser -`editCodeService` into pure node-testable `common/searchReplaceMatch.ts`, and FIXED a real -silent-corruption bug: the EXACT-match path returned the first `indexOf` hit WITHOUT a uniqueness check, -so a non-unique ORIGINAL block silently edited the FIRST of several identical matches (wrong-location -edit). The whitespace-FALLBACK path already rejected non-unique; now the exact path does too, for a -whole-file (`startingAtLine === undefined`) search, using the existing graceful "must be unique" error -(`_errContentOfInvalidStr`). Positional/streaming matching (`startingAtLine` set) is unchanged. All 3 -callers handle the `'Not unique'` string (main apply THROWS the descriptive error; streaming diff-area -reverts + re-prompts; stream-cursor is `startingAtLine`-gated) - and the diff-area caller could already -get `'Not unique'` from the fallback path. Verification: tsgo 0; +14 tests (**474 -> 488 passing, 0 -failing**); **400,000-run differential fuzz** vs pre-fix = 28,982 divergences, ALL exactly the intended -case (startingAtLine undefined + exact + non-unique), 0 unexpected (~7% rate shows how reachable the -silent-wrong-edit was); **4-agent adversarial review**: fix correct + all callers safe; cdp atomic-edit -(7B) no regression. - -`c4ee27d78ac` -- fixed a PRE-EXISTING TDZ crash the SR review surfaced (independent of the SR fix). In -the streaming/manual Fast-Apply path (`_initializeSearchAndReplaceStream` -> `runSearchReplace` -> -`onText`), the `hasOverlap` `.some()` callback referenced `startLine`/`endLine` that were `const`-declared -LATER in the same block - a temporal dead zone that threw `ReferenceError: Cannot access 'startLine' -before initialization` on the 2nd+ block of any multi-block "Apply" (when the callback actually runs). -tsgo/tsc do NOT catch TDZ. Fix: compute the block's final-range bounds (`thisBlockRange`) BEFORE the -overlap check (guarded for the error-string case); the callback uses them; the later -`const [startLine, endLine]` for the diff-area add is unchanged. Behavior preserved on the 1st block + -error-string bail; the 2nd+ block now does the INTENDED overlap check instead of crashing. Verification: -tsgo 0; 488 passing; a scope-pattern repro confirms old-order throws ReferenceError on a non-empty array -while new-order computes overlap correctly; cdp-smoke 11/11 (boot healthy). HONEST LIMIT: the multi-block -ClickApply streaming path is not node-testable and impractical to drive live with the local harness -(the agent's `edit_file` uses the INSTANT `instantlyApplySearchReplaceBlocks` path, not this streaming -one) - validated by the repro + the prior adversarial review which endorsed this exact fix. Then -`242bb38a6f3` -- extracted the agent edit_file apply TRANSACTION (`_instantlyApplySRBlocks`) into pure -node-testable `computeSearchReplaceResult` in `common/searchReplaceMatch.ts`: validate-ALL blocks -> -map to [origStart,origEnd] char spans -> sort -> REJECT on any overlap -> apply RIGHT-TO-LEFT (all-or- -nothing; a non-ok result throws before any write, so no partial/corrupt write). This is the path the -agent actually uses, previously untested (browser layer). Byte-identical (char-offset math / sort / -overlap / right-to-left apply verbatim; the throw moves to the caller via `{ok:false, reason, -blockOrig}`). tsgo 0; +10 tests (**488 -> 498 passing, 0 failing**); 300,000-run differential fuzz = 0 -mismatches; cdp atomic-edit-e2e (7B) no regression. NOTE: the agent SR apply was ALREADY transaction-safe -(validate-all-first + single write; Phase 1 made the disk save atomic) - this makes that guarantee -TESTED. Remaining Phase 5 (NOT done): per-hunk / partial accept, streaming-diff race with final apply, -apply verification (diagnostics/lint/tests), edit provenance, symbol-aware refactor. - -`4042deae2eb` + `1b0842afcee` -- **apply VERIFICATION** (the next Phase 5 DoD item). Before: the -three agent edit tools (edit_file / rewrite_file / multi_edit) each applied, then did a FIXED -`timeout(2000)` and surfaced ALL current lint errors -- racy (a fixed guess can miss a slow language -server) and noisy (the model got pre-existing errors it did not cause, with an "if this is related" -hedge). Now: (1) pure tested `common/applyVerification.ts` -- `diffDiagnostics(before, after)` does a -multiset diff keyed on severity+code+message (line ignored, since an edit renumbers lines) -> -{ introduced, resolved, preexistingCount }, plus `summarizeApplyVerification` (+11 tests, **538 -> -549**); (2) wired into toolsService: each edit tool snapshots diagnostics BEFORE apply, waits for -diagnostics to SETTLE (`_waitForDiagnosticsToSettle`: resolve after 500ms quiet on -IMarkerService.onMarkerChanged, hard cap 3000ms, always resolves), then surfaces ONLY the problems -the edit INTRODUCED (mapped to the existing LintErrorItem result contract -- no type ripple), or null. -Pre-existing problems are no longer reported. tsgo 0; LIVE atomic-edit-e2e (7B) completes -> the -settle-wait promise resolves (no agent-loop hang), clean edit -> no spurious lint message. HONEST -LIMIT: the introduced-error-surfaced path is unit-tested (pure diff); driving the 7B to emit broken -code on demand is unreliable, so that exact surfacing is not driven live. `summarizeApplyVerification` -is tested-but-unwired (the wiring reuses the lintErrors contract; the richer summary is available for -a future result-shape change). Still remaining Phase 5: per-hunk/partial accept, streaming-diff race, -edit provenance, symbol-aware refactor. - -### NOTE (2026-06-11): a background comment-cleanup agent landed on a STALE base -- do NOT merge -A `cleanup/comment-pass` branch (comments-only sweep of the cortexide contrib, 83 files / 5 commits / -~2032 deletions, tsgo 0, parser-verified byte-identical non-comment tokens) was produced by a -background agent in an isolated worktree. BUT the worktree was based on `4036eb0bb4c` -- an EARLY -branch commit (~158 commits behind HEAD, BEFORE Phase 0): it still contains `common/telemetry/` -(deleted in Phase 0) and `offlinePrivacyGate.ts` (renamed in Phase 8), and lacks every Phase 0-8 file. -Merging it would revert Phase 0-8 and resurrect deleted files. It is therefore UNMERGEABLE and must be -REDONE on current HEAD if the cleanup is still wanted. (The sibling logo agent only worked because its -one file, `editorgroupview.css`, was untouched by the modernization commits, so its change cherry-picked -cleanly -- now landed as `fffff558568` + circular `92bad0fa096`.) LESSON: an `isolation: worktree` -agent here was NOT based on the active branch HEAD; verify a worktree agent's base (e.g. that a known -recent file exists) before trusting/merging its branch. - -### Phase 8 — Real local-first privacy: genuine local-only egress enforcement (2026-06-11) - -The north-star ("private/local-first, never leaks a secret") turned into a TESTED guarantee. -Starting point was FAKE SAFETY: `common/offlinePrivacyGate.ts` only checked `navigator.onLine` and -never enforced privacy; `routingPolicy === 'local-only'` was merely a model-routing PREFERENCE -(consumed only by modelRouter/modelFailover/chatThreadService for model selection), NOT a hard egress -boundary. A 6-agent read-only map workflow (`map-egress-surface`, journal -`map-egress-surface-wf_db720342-e56.js`) inventoried every egress point and found the ungated leaks. - -Canonical signal (reused, NOT a new setting): `routingPolicy === 'local-only'` (or task -`requiresPrivacy`).

Where things stand (DONE vs TODO) - -- **Phase 0 — Stop shipping broken promises: ✅ COMPLETE.** Registered the 11 hidden `cortexide.*` - settings (pure SSOT `common/cortexideConfigKeys.ts` + now-imported `cortexideGlobalSettingsConfiguration.ts`); - fixed false "27 tools" -> dynamic **35** (`common/builtinToolNames.ts`, compile-guarded); de-lied the 2 - comparison docs; removed 11 dead files + `common/telemetry/`; `phase0ClaimVerification.test.ts`. -- **Phase 1 — Protect user workspaces: ✅ COMPLETE + LIVE-VALIDATED.** - - #1 atomic writes (applyEngineV2 + agent path via `ISaveOptions.atomicWrite`); live: edit persists, no temp leak. - - #2 durable rollback (`common/agentFileOps.ts` + journal in chatThreadService); live: create-removal, - delete-recreate-with-content, edit-restore all on disk. - - #3 gather read-only at DISPATCH (`common/toolPermissions.ts`); live: blocks a real model-emitted write. - - #4 terminal danger BLOCKS + cwd containment (`common/commandRisk.ts`). - - #5 secret redaction — VERIFIED already secure-by-default (sendLLMMessageService). - - #6 Workspace Trust at dispatch (`IWorkspaceTrustManagementService` injected). - - Residuals (documented, not blockers): gate D untrusted-block + B/C real destructive commands not - *driven* live (dev launch auto-trusts; won't run `rm -rf`) — same chokepoint is live-proven via gather. -- **Phase 2 — Testable agent runtime: 🔄 IN PROGRESS (wiring landed).** - - DONE (zero-risk): `common/agentLoopDecisions.ts` (5 pure decision fns) + **57 tests**. - - DONE (behavior-preserving + live-validated): **Edits A/D/B WIRED** — the loop now delegates the - tool-error cap (`updateConsecutiveToolErrors`, `db1bbdb0abd`), compaction+overflow - (`computeCompactionOverflowDecision`, `53f6a12d0c0`), and the iter-cap escalation gate - (`shouldEscalateModel`, `cac44f0039a`). Verified by a 6-agent adversarial review (0 reachable - divergences) + CDP live (7B happy-path completes; 1.5b thrash -> escalation fires). See - `docs/MODERNIZATION-BASELINE.md` "Phase 2 — wiring Edits A/D/B". - - **NEXT (own reviewed PRs):** Edit C (llmError gate), Edit E (completion routing), the - parse-classifier (`classifyToolCallFromLLMResponse`); then the module split (AgentLoopController / - ToolCallParser / ToolPermissionEngine / AgentPlanner / ModelSelectionEngine / AgentContextBuilder - / AgentSessionStore / AgentVerifier). `docs/PHASE2-WIRING-PLAN.md` still holds the Edit C/E sketches. -- **Phase 3 — Model-agnostic provider platform: 🔄 STARTED.** First increment (`b6773313bee`): - pure SDK-free tool-call-capture + message-format helpers extracted from the electron-main 18-provider - dispatch into node-tested `common/providerToolFormat.ts` (the node runner excludes electron-main). See - `docs/MODERNIZATION-BASELINE.md` "Phase 3". Remaining: SDK-typed schema builders / per-provider - request-response need SDK-type extraction or a mock-fetch harness; capability registry; fallback order. -- **Phases 4-10 — NOT STARTED.** (RAG / apply-UX / agentic-UX / MCP+plugins / privacy / CI / positioning). - Original spec is in section 7 below. - -**Tests:** cortexide node suite **320 passing, 0 failing**. tsgo 0 errors. CDP smoke 11/11. Renderer -safety checks 26/26. Phase 2 wiring live-validated (happy path + cap/escalation). - ---- - -## 2.
