Eva-brain memory report

Type: agentic-system-analyses/types/agentic-system-memory-report.md

Boundary and evidence

Eva retains a local Git-backed Markdown brain, not an Eva-owned conversation history. This report includes source acquisition, model-authored pages, answer-derived analyses, configuration and instruction reload, operation logs, worktree admission and withdrawal, desktop consumption, and MCP navigation. The source boundary and source register are boundary. SRC-1 is the repository at 706fb91f4ee851cc355785f4e7c6eab37146938f. Source reads establish implementation or doctrine/design, not observed operation. External runtime histories, provider memory, compaction and weights remain opaque; no runtime execution, tests or services were invoked.

The supplied runtime is a provisional baseline. Direct reads added the complete canonical docs/EVA_BRAIN_STANDARD.md, schema/EVA.md, MCP server/loader, wiki parser/vault/lint, and selected Rust/UI ranges to assess transformations and consumers. The table distinguishes direct inspection from reliance on supplied records. Available files not read are not access gaps.

Core ideas

  1. The wiki is the durable intermediary. Ingest prompts request integration into existing pages, not an append-only transcript. Later queries search that maintained artifact. Accepted edits can therefore shape evidence available to future tasks, but neither structural admission nor delivery proves truthful content or improved answers (MEM-OBJ-knowledge-pages, MEM-BAP-wiki-evidence).
  2. Different retained results have different controls. Ingest may auto-merge without per-content human approval. Saving a query or profile result always requires a separate decision. Settings and source copying are other writers, not instances of the ingest gate (RT-RTE-source-ingest, RT-RTE-analysis-save, RT-RTE-brain-settings).
  3. Read-back is requested and lexical, not an unsolicited memory push. A model requests MCP search/full-page/graph tools or uses native filesystem search. MCP ranks title/alias/body matches and caps results; it does not select by embedding similarity. Working-set IDs constrain instructions, not the loader. Separate subprocesses bound Eva's task context but do not prove clean external-runtime histories (MEM-RTE-mcp-navigation, annotation on RT-RTE-vault-query).
  4. An operational trace has a second, exact software consequence. The log retains outcome prose, but enqueue treats source-name substring presence as an eligibility veto, including rejection. This is not a learned semantic policy or a content fingerprint (MEM-OBJ-log).

Shared records

Components

none declared in this member

Operative objects

MEM-OBJ-raw

Label: Raw source collection

SRC-1, apps/desktop/src-tauri/src/ingest.rs, schema/EVA.md: source bytes in the vault filesystem under raw/, committed to local Git before queued processing. Textual documents carry natural-language evidence; arbitrary selected file payloads remain opaque to this analysis. Copying does not establish extraction capability for every format. Initial provenance is user-supplied or manually deposited files; Eva does not establish their truth or external origin. The software copies by filename only when the destination does not exist, then also discovers non-hidden immediate files. Human selection is supported in the shipped UI; generic command callers and manually dropped files leave per-content human approval unresolved. This is acquisition, not derived memory or model training.

The ingest model reads raw/{source}; MCP wiki loading excludes it. Raw is protected at the ingest admission gate, not proven physically immutable against every actor. The closest supplied record is RT-RTE-source-ingest, a route containing acquisition rather than this retained object. No supplied object counterpart after comparison.

if sp.canonicalize().ok() != dest.canonicalize().ok() && !dest.exists() { fs::copy(&sp, &dest).map_err(|e| format!("copy {name}: {e}"))?; } --- apps/desktop/src-tauri/src/ingest.rs

MEM-OBJ-knowledge-pages

Label: Entity concept and index prose

SRC-1, schema/EVA.md, apps/desktop/src-tauri/src/ingest.rs: natural-language body content of retained entity/concept/index Markdown pages in the vault filesystem and local Git. Their IDs, links and metadata are separately described by MEM-OBJ-page-metadata. Source-derived claims are model-authored under search-before-write, merge-over-duplicate, provenance and profile guidance. Existing imported pages and starter pages can precede those transformations; unknown historical authorship does not erase the known later model write route.

These are derived subject knowledge and navigation prose, not raw traces. Ingest can revise existing pages or create new ones. The gate admits mechanically clean changes without individual human approval; a held proposal can be accepted or rejected. Later consumers include the person, further ingest agents, query, health and profile tools. Model consumers interpret prose as evidence; the instruction contract is a distinct authority path RT-BAP-vault-contract. Closest supplied object RT-OBJ-ingest-worktree is temporary proposal staging, not the durable accepted page referent; no duplicate declaration intended.

  1. Search the existing Markdown pages with rg and read the relevant pages before editing. Prefer merging new information into existing pages; create a page only for a distinct entity or concept worth linking from elsewhere. --- apps/desktop/src-tauri/src/ingest.rs

MEM-OBJ-summaries

Label: Source summary prose

SRC-1, schema/EVA.md, packages/wiki-lib/src/lint.ts: natural-language source digests stored as Markdown under summaries/ by the contract, in local Git after admission. Distinct from MEM-OBJ-knowledge-pages because summaries have a dedicated required source field and dedicated lint checks. Their source path is symbolic provenance metadata, not the digest's explanation. The model derives the digest from a raw document; initial imported digest authorship is unresolved. The contract requests exactly one source per summary, while lint checks only a nonempty source beginning raw/, not uniqueness, source existence or entailment. The same ingest admission and later page readers apply; no independent truth oracle is supplied. No supplied object counterpart; closest route is RT-RTE-source-ingest.

| summary | A digest of exactly one source document. | summaries/ | --- schema/EVA.md

} else if (!source.startsWith('raw/')) { --- packages/wiki-lib/src/lint.ts

MEM-OBJ-analyses

Label: Analysis answer and evidence prose

SRC-1, apps/desktop/src-tauri/src/ingest.rs, apps/desktop/src/main.ts, schema/EVA.md: natural-language reusable syntheses/answers in filesystem Markdown and local Git, with symbolic reference metadata assessed in MEM-OBJ-page-metadata. Analyses can arise from ingest under the contract or from the explicit answer-save formatter; bootstrap can also seed analyses/starting-point.md. Thus not every analysis is a retained query trace.

For explicit saves, lineage is supplied question + answer prose + citations → Rust Markdown with Question, Answer and Evidence sections → reviewed branch → accepted wiki. The formatter trims answer text, constructs a title/date and inserts evidence links. Its sources frontmatter keeps safe raw/ references, falling back to a safe summaries/ citation when that citation has no raw reference. Evidence body entries can preserve other safe source strings. Safety filtering rejects control characters and bracket/pipe syntax, not unsupported claims. Saved products preserve a question, answer and citation list, not necessarily the model's derivation or reasons. Later page reads can expose those retained sections; they cannot recover omitted reasoning.

Closest supplied route RT-RTE-analysis-save already owns save progression and admission. This record adds the durable artifact identity, not another save route. UI profile results use that same route, not a separate automatic memory writer.

MEM-OBJ-page-metadata

Label: Page identifiers frontmatter and links

SRC-1, packages/wiki-lib/src/parse.ts, packages/wiki-lib/src/vault.ts, packages/wiki-lib/src/lint.ts, packages/eva-mcp/server.mjs: symbolic page IDs, type/source fields, link targets and derived adjacency are distinct from natural-language page prose. Markdown files persist the frontmatter/link syntax; parser output and graph structures are reconstructed in memory. IDs derive from normalized paths without .md; frontmatter parsing handles simple key/value lines, not general nested YAML. Titles and aliases have natural-language meanings for people/models but also literal matching roles for software. No dense vector store is established by these inspected selection paths.

The parser retains strings, body and extracted link targets, not a semantic claim graph or a separate warrant record. Link resolution uses case-insensitive ID, then stem, then title. MCP search additionally matches aliases. Frontmatter aliases are not an additional resolver branch in resolveLink. Graph/lint consume fixed symbolic fields; the model receives readable metadata and text. Lint's orphan test is inbound membership, not reachability from the index, and summary source-prefix checking does not establish source support. Parser reconstruction is a transformation of retained files, not a new learned artifact.

No supplied object counterpart; closest supplied assessment is RT-CLM-structural-gate, whose limits this direct inspection supports.

Nested YAML is out of scope for this vault format. --- packages/wiki-lib/src/parse.ts

vault.pages.find((p) => p.id.toLowerCase() === t) ?? vault.pages.find((p) => p.stem.toLowerCase() === t) ?? vault.pages.find((p) => p.title.toLowerCase() === t) ?? null --- packages/wiki-lib/src/vault.ts

MEM-OBJ-log

Label: Operation log and eligibility text

SRC-1, apps/desktop/src-tauri/src/ingest.rs, apps/desktop/src/main.ts: filesystem log.md, Git-committed by Eva. Natural-language operation/summary/rejection prose is one part; source-name occurrence as a software matching input is a second operative use. Eva appends date, operation, subject and body. The summary originates from the agent for successful ingest; rejection prose is a software constant after a human decision. This is trace retention, not automatically revised task guidance. The log is excluded from wiki MCP search and loaded separately into desktop logRaw.

The enqueue consumer does read the accumulated log on later calls. It removes any candidate filename occurring anywhere in its text. Consequently a rejected source stays in raw but is ordinarily not retried; incidental substring collisions may also suppress processing. No content hash, status parse or semantic assessment intervenes in that predicate. This is behavior-shaping retained operational state without establishing learned capacity. Closest supplied record RT-RTE-source-ingest already reports this effect; this declaration is its retained object, not a duplicate route.

Routes

MEM-RTE-mcp-navigation

Label: MCP retained wiki navigation

SRC-1, packages/eva-mcp/server.mjs, packages/eva-mcp/vault-io.mjs: model/tool caller request → reload files → parse vault → lexical or graph operation → JSON text tool result → external model invocation. Owner: MCP server for deterministic selection; external model for request choice and subsequent interpretation. The four registered tools are search, read_page, neighbors, shortest_path. This is a navigation subroute of the broader query/ingest/advisory loops, not an alternative writer. Closest supplied routes RT-RTE-vault-query and RT-RTE-source-ingest overlap by consumption; they are not the same endpoint-level selector route. The server itself has no registered write operation.

  • implementation conclusion status: wired
  • operation conclusion status: uninspected
  • Immediate return: JSON serialized as MCP text, containing up to ten ranked search matches/excerpts; full frontmatter/body and outgoing/incoming links for read_page; neighbor IDs; or an undirected shortest path/null and errors for invalid IDs.
  • Later read-back: each call reloads retained wiki files, so admitted prior-task content and current worktree edits can reach later invocations; ordinary same-task file visibility alone is not cross-task memory.
  • Delegated visibility: caller receives selected readable fields, not raw sources, operating files, Git history or log through this loader; other filesystem tools may read those separately.
  • Selection predicate: search lowercases whitespace-separated query terms, gives a ten-point title/stem/alias hit bonus plus count of body-hit terms, sorts descending and takes ten; excerpt spans from up to 60 characters before to 120 after the first matching body position. read_page uses exact ID then stem/title fallback; neighbors uses exact ID; shortest_path uses exact endpoints and breadth-first traversal of undirected links.
  • Invalidation or expiry: no persistent search cache; reload per call makes filesystem edits/deletions visible on the next request; no semantic expiry or age-based selection.
  • Activation or effect: delivers selected retained material for model interpretation, without proving that a returned page changes the answer or edit.
  • Evidence limits: no observed calls or causal evidence; no token-budget enforcement in the server; full-page reads have no server truncation budget; underlying runtime window/compaction is outside the frozen evidence.

// Reload per call so the agent's own writes during a run are visible. const vault = () => loadVault(VAULT); --- packages/eva-mcp/server.mjs

MEM-RTE-desktop-reload

Label: Desktop retained brain reload

SRC-1, apps/desktop/src/main.ts: openVault → ensure missing schema → settings/log/files reads → buildVault/buildGraph/lintVault → UI graph/explore display. Owner: frontend orchestration and Rust bootstrap for missing infrastructure. This adds a human-facing consumer route to RT-RTE-source-ingest and RT-RTE-analysis-save, not another model invocation or write-admission mechanism. No supplied route has this exact reload/display referent.

  • implementation conclusion status: wired
  • operation conclusion status: uninspected
  • Immediate return: rebuilt in-memory vault, graph, clusters and issues rendered for the person; separately loaded log and settings.
  • Later read-back: accepted Markdown is reread on opening/reopening, including the merge-triggered reload described in the supplied runtime; no model delivery follows merely from rendering it.
  • Delegated visibility: inapplicable — reload is frontend/Rust filesystem processing, not a delegated model task.
  • Selection predicate: recursive Markdown collection skips dot entries, root raw directory and root infrastructure files; index remains included. Whole collected wiki is parsed, not query-ranked.
  • Invalidation or expiry: opening replaces the in-memory vault/graph and clears health state; files persist until edited/deleted externally or through admitted edits.
  • Activation or effect: person can inspect retained pages/links/issues; no observed human reliance or quality gain.
  • Evidence limits: source-level reload wiring only; preferences, display filtering and every rendering surface were not exhaustively inspected and establish no model memory pathway here.

Behavioral-authority paths

MEM-BAP-wiki-evidence

Label: Retained wiki as later task evidence

SRC-1, apps/desktop/src-tauri/src/ingest.rs, schema/EVA.md: consumers are later ingest/query/health/profile models and the person. Channels are filesystem reads/search, MCP selected page text and desktop display. Force for models is natural-language evidence under task instructions: query asks to answer from the brain, ingest asks to merge with it, health asks to diagnose with supporting page IDs. This is informational authority, not a software truth guarantee or an instruction privilege automatically granted to every page. Horizon spans later tasks on the retained brain until edits or removal. Actual compliance/activation/benefit are uninspected.

Distinct from RT-BAP-vault-contract: that path carries operating rules and parsed configuration, whereas this path carries subject knowledge. Source trust is requested rather than established: the health prompt explicitly forbids following source-material instructions; citation presence alone does not establish entailment or source independence.

You are answering a question from an Eva LLM Brain. The brain is a persistent, curated knowledge artifact; answer from it rather than general knowledge. --- apps/desktop/src-tauri/src/ingest.rs:2640-2695

Annotations

On RT-OBJ-ingest-worktree

Memory-specific distinction: proposed Markdown exists in a Git-backed temporary frame, but it is not yet the main vault's retained knowledge. The agent's task state/inner reasoning is not copied into the vault as a checkpoint by the inspected gate. Admitted page edits and summary log escape; error or rejection calls cleanup, force-removing the worktree and branch. Raw source state committed before dispatch survives rejection. Git history retains accepted changes, not an Eva-owned alternate compressed conversation checkpoint. Evidence: SRC-1, apps/desktop/src-tauri/src/ingest.rs, direct run_job/gate/cleanup and rejection reads; progression and supporting gate passages remain in RT-RTE-source-ingest.

On RT-RTE-source-ingest

Write agency: person supplies/chooses sources; external model proposes page text and revisions; Rust physically commits and automatically admits proposals meeting the structural predicate. Starting ingest is not per-page human approval. Held proposals add human acceptance/veto. Raw-to-derived-to-later-consumer chain is MEM-OBJ-raw → MEM-OBJ-knowledge-pages/MEM-OBJ-summaries/MEM-OBJ-analyses → MEM-RTE-mcp-navigation or native search in later tasks. These are source-fed curation, not established automatic learning from interaction traces. The operation log is the separate trace-fed result with filename eligibility authority (MEM-OBJ-log). Neither citation metadata nor summary prose guarantees retained reasons for every synthesized claim. Evidence: SRC-1, apps/desktop/src-tauri/src/ingest.rs, schema/EVA.md; supporting passages above and in the supplied route.

On RT-RTE-analysis-save

The retained result is MEM-OBJ-analyses. Question, answer and filtered references survive formatting; complete tool histories/model reasoning do not follow from that representation. The UI provides a human save and review decision, while generic API caller identity remains unresolved. Model/caller authorship is separate from Rust I/O and human admission. A query output is derived work; saving it provides a use-output-to-knowledge path, but no automatic performance-assessment-to-method-revision loop is demonstrated. Accepted analyses enter ordinary wiki search and can later be treated as evidence, creating possible synthesis-on-synthesis lineage without an enforced independent-source check. Evidence: SRC-1, apps/desktop/src-tauri/src/ingest.rs, formatter/preparation/decision, and apps/desktop/src/main.ts, profile-save caller; source support in the object record and supplied route.

On RT-RTE-vault-query

Context selection is model-requested. The scope list is at most 250 IDs; each is at most 512 characters, nonempty and control-character-free, with duplicates removed. This is a prompt input budget, not a token window or hard per-tool filter. EVA.md and index.md are permitted orientation even under nonempty scope. MCP tools accept no working-set argument and use the whole root; native rg/filesystem access is an alternative. Therefore requested scope cannot establish material exclusion from the model's accessible context. Evidence: SRC-1, apps/desktop/src-tauri/src/ingest.rs, normalize_working_set/working_set_instruction, and MEM-RTE-mcp-navigation. No source excerpt duplicates the supplied route's scope passages.

On RT-RTE-brain-settings

Instruction memory is retained EVA.md, agent entry files and manifest/profile values. Bootstrap's missing-only writes preserve earlier or imported instructions, so initial content control may be unknown; later UI settings changes have an explicit human input path and software validation. These texts are not automatically rewritten from agent experience by the inspected ingest route, which protects them. Their later consumer and authority are already established in RT-BAP-vault-contract. Evidence: SRC-1, apps/desktop/src-tauri/src/ingest.rs, bootstrap/protected paths, schema/EVA.md; supplied route retains the missing-only-write passage.

On RT-RTE-advisory-tools

Read-back supplies retained wiki to advisory models, but returned health findings do not themselves update wiki or instruction memory. The Codex prompt requests evidence-backed contradictions, provenance weaknesses, staleness and gaps; its nextStep is a suggested action. That is a request for diagnosis, not proof of semantic criticism or an executed correction. Profile products may become durable analyses through separate human-reviewed saving. Evidence: SRC-1, apps/desktop/src-tauri/src/ingest.rs, Codex health prompt, and apps/desktop/src/main.ts, profile-save caller; source passages retained by the supplied route and MEM-OBJ-analyses.

Write side

Acquisition admits selected and manually deposited source bytes before synthesis. It neither replaces a same-named destination nor authenticates source claims (MEM-OBJ-raw). Creation/import/bootstrap seed or preserve retained contract and starter content. Settings directly change future guidance/runtime choices through a separate validated command; not all initial imported text has known authorship (RT-RTE-brain-settings).

Curation is model-directed integration under fixed shipped instructions: search existing knowledge, merge rather than duplicate, preserve provenance, update index. The prompts establish requested transformation, while gate/source establishes capacity to retain edits, not observed faithful synthesis. Summaries, entity/concept pages and analyses remain separately identifiable because their lineage and checks differ. Structural lint has no semantic truth oracle (MEM-OBJ-summaries, MEM-OBJ-page-metadata, RT-CLM-structural-gate).

Ingest admission checks protected paths, then deletion/new-issue predicates. The person may accept a held proposal despite issues. Rejection removes the proposed branch/worktree, keeps the raw source and appends a rejection log. Later enqueue interprets that retained rejection text as a reason not to schedule the source again. Deletion or rename of knowledge pages forces review, not automatic expiry. Accepted removals become visible on loader reload; content history persists in Git, but no automatic semantic rollback is established (RT-RTE-source-ingest, MEM-OBJ-log).

Query/profile saving is a second transformation and admission route: structured product → formatted analysis with question/evidence → mandatory review → merge or discard. It preserves the answer, not an independently verified rationale. Rejected saved analyses leave a log, not a wiki answer. Health is advisory and does not close an automatic evaluate-to-revise chain (RT-RTE-analysis-save, RT-RTE-advisory-tools).

The trace-fed writes established here are the operation log and optional answer-derived analysis. Only the former has a direct deterministic later scheduling consumer; the latter offers reusable knowledge to subsequent model tasks. Neither proves improved capacity. No Eva-owned conversation compaction/checkpoint alternative was established in the inspected task/save/gate paths; external runtime compaction and automatic memory remain uninspected rather than absent.

Read-back

The query route explicitly instructs reading EVA.md and index.md, searching maintained pages and answering only from the brain. Ingest reads the selected raw source plus relevant existing wiki. Health/profile tools similarly request retained evidence. Native filesystem search and MCP are alternative selection channels, not two different memory stores (RT-RTE-vault-query, RT-RTE-source-ingest, RT-RTE-advisory-tools).

MCP is request-driven: the model supplies a query/page/graph endpoint, then software selects retained fields. A requested page ID is an address, not automatic relevance targeting. Search actually ranks by query terms with a ten-match output budget; read_page can reload full content with no server token cap. Graph tools return connectivity, not the source documents or an explanation of why a relation holds (MEM-RTE-mcp-navigation). There is no independent unsolicited retrieval trigger established here. Desktop reload is a separate actual consumer, not a hypothetical library caller (MEM-RTE-desktop-reload).

At Eva's boundary, each task launches a separate external-runtime subprocess with generated inputs rather than carrying an Eva foreground chat forward. This resembles a task frame: selected inputs enter, final product/summary and proposed filesystem edits escape. It is not a proven clean-context boundary because external runtimes may load their own instructions or histories. Nor is the durable wiki a by-reference model heap: page content enters context by value through reads; Git/file identity does not define model-window liveness. Old task internals are not retained by Eva's inspected save formatter, while full pages remain reloadable through tools. No source-based model-window trim policy, preferential removal rule or summary budget can be attributed to Eva from these paths; runtime internals are outside inspection (RT-RTE-vault-query, RT-OBJ-ingest-worktree, MEM-RTE-mcp-navigation).

Integration issues

  • No correction to a supplied runtime fact is proposed. Direct parser/lint/navigation reads support its qualifications about structural admission and prompt-only working sets.
  • Object/route overlap is intentional, not a duplicate identity: MEM-OBJ-raw, MEM-OBJ-log and accepted wiki objects characterize retained results of RT-RTE-source-ingest; they do not replace that route or the temporary RT-OBJ-ingest-worktree. MEM-OBJ-analyses characterizes a durable product of RT-RTE-analysis-save, not a competing save route. No candidate record is identified as a possible duplicate after this comparison.
  • MEM-RTE-mcp-navigation supplies the concrete selector shared by model routes, while MEM-RTE-desktop-reload adds the actual person-facing consumer. Reconciliation should keep these subroutes distinct from their task-level invocations.
  • Initial imported knowledge/instruction provenance, source truth and actual model adherence remain unresolved locally to MEM-OBJ-raw, MEM-OBJ-knowledge-pages, MEM-OBJ-summaries and RT-RTE-brain-settings. These prevent claims of uniformly human-controlled content, verified knowledge or causal benefit, not the known later write/reload chain.
  • External runtime memory loading, histories, compaction and provider internals remain unresolved for RT-RTE-vault-query and RT-OBJ-ingest-worktree. These prevent a whole-model-context isolation/retention claim. They do not make the explicit Eva task outputs or file read-back unknown.

Limitations and checks

The frozen checkout HEAD was rechecked against the boundary before source inspection. All added evidence is SRC-1 at that revision; there was no new source identity or execution layer. The supplied member/type/record contracts govern this memory report. Static source demonstrates implemented write/selection/admission wiring only; no observed run or causal experiment establishes model compliance, retained factual correctness, activation, learning or improvement. No exhaustive UI, adapter, dependency or filesystem security audit is claimed. External weights and runtime memory remain outside the source boundary, as stated in the supplied model components and boundary.

Validation: the required role-memory deterministic check passed after correcting two quotation attribution ranges against a reread of the frozen source. The check establishes structural form and quotation occurrence, not semantic validity or acceptance.
