A memory used to have one state: present. A session could not be reloaded
without searching, nothing separated what a person said today from what the
store ingested a year ago, and two statements that disagree about a number
were both handed to the reader as if the store believed both.
Schema v10. Atoms gain session_id, importance, recall_count, last_recalled_at
and archived_at; two tables arrive beside them — consolidations (one watermark
per holder+scenario lane) and conflicts (a pair, the term they disagree on,
both values, and whether anyone has settled it). v_atoms_current now also
hides archived rows, and apply() drops the view before rebuilding it because
CREATE VIEW IF NOT EXISTS would keep the old body and ignore the archive.
Working memory is a read, not a store: `working <holder> <session>` returns
what that session recorded, in order, with no search involved. Consolidation
rolls a lane's new memories into one standing summary and moves the watermark
to the newest memory actually rolled up — not to the clock of the pass, which
made a second pass count the same memories twice. The archive rule is stated
in the command that runs it (recorded before N days, never returned by a
search, importance at or under a floor) rather than hidden in a decay formula
nobody measured; --dry-run names the victims first.
A conflict is recorded when a new memory repeats a label with a different
number in the same holder's same scenario. Retrieval drops the older side
while the conflict is open and both sides answer again once it is settled:
settling is not superseding, and a word-only disagreement is left alone
because a reworded sentence would fire on every paraphrase. Numbers are keyed
to both the memory's subject and the nearest preceding label, measured: the
two thermostat sentences share only their subject, so a nearest-word-only rule
found nothing.
Search now counts the memories it handed back, which is the only use estimate
the store has, and the archive rule reads it. The dense index applies the same
currency rules as the view, so an archived memory cannot stay findable through
one leg while the other hides it.
Two reads over HTTP (working, conflicts) and two tools over MCP
(working_set, memory_conflicts); curation stays with the operator because an
agent should not decide what its own past is worth. remember and supersede
carry a session id; importance does not cross MCP, because recall_count is
observed and importance is stated.
Gates: 366 passed; ruff clean; mypy 24 errors in 9 files, the recorded 9cb46c1
baseline, net 0; pyright 0 on the touched files; go build/vet/test and gofmt
clean; mcp_write_smoke PASS.
Ely-Eye MCP
Ely-Eye MCP exposes a local Context Cartridge memory store as a stdio Model Context Protocol server for coding agents such as Codex and Claude Code.
The server is local-first and read-only against <ely-eye-home>/data/ely_eye.sqlite. It reads Evidence Atoms, cartridge manifests, Memory DNA, proof-suite artifacts, HashHop proofs, and compiled evidence packs. The production database is never modified.
It can be deployed for any .ely_eye store. Identity is anchored on the database file, not on the Ely-Eye repository layout, so the server walks up from the working directory to find .ely_eye/data/ely_eye.sqlite, or takes an explicit --ely-eye-home.
One-command setup
The installer downloads a checksum-verified prebuilt binary for the platform when a tagged release is available, otherwise it builds from source with Go from a repository checkout. Either way it installs the binary into <ely-eye-home>/bin and registers the server with Codex and Claude Code. No Docker.
Windows:
powershell -ExecutionPolicy Bypass -File .\ely-eye-mcp\install.ps1 -Client both
Linux and macOS:
bash ./ely-eye-mcp/install.sh --client both
Force a source build (requires Go 1.25 or newer):
bash ./ely-eye-mcp/install.sh --method source
Codex registration uses codex mcp add. Claude Code project registration writes .mcp.json at the project root; --scope user registers through the Claude CLI instead.
Manual run
From inside a project that owns an .ely_eye store:
go run ./cmd/ely-eye-mcp server
Or point at an explicit store:
go run ./cmd/ely-eye-mcp server --ely-eye-home /path/to/.ely_eye
Tools
ely_eye_status returns atom, source, cartridge, token, and cache-layer counts.
list_cartridges lists local Context Cartridges with manifest JSON and Memory DNA.
get_cartridge reads one cartridge plus artifact metadata, memory capsule index, and asset report.
search_atoms queries the local SQLite FTS index and returns ranked Evidence Atoms.
fetch_atom reads one Evidence Atom by exact id.
compile_context compiles a question into a local evidence pack with the same profile names used by the app (live_demo, extreme_context, library_100m, research_theater).
list_proof_suites lists PRD proof suites under <ely-eye-home>/data/eval_proofs.
list_hashhop_proofs aggregates HashHop and Visual HashHop long-context addressing proofs by kind, hop count, and token budget, with pass counts and example proofs. Proofs are deduplicated by content-derived id.
get_proof_suite reads one PRD proof suite by id, including all checks and a summary of its HashHop proofs.
Resources
ely-eye://project/prd, ely-eye://project/readme, and ely-eye://project/mcp-research expose PRD.md, the project README, and these research notes when those files are present next to the store.
Releases
Pushing a mcp-v* tag runs .github/workflows/mcp-release.yml, which cross-compiles the pure-Go server (CGO disabled) for Linux, macOS, and Windows on amd64 and arm64, then publishes the archives with a SHA256SUMS manifest to a GitHub Release. The installers consume those assets.
Security posture
The server opens SQLite read-only with mode=ro and PRAGMA query_only(1), and uses busy_timeout so reads tolerate concurrent writes by the Ely-Eye app. Tools expose structured outputs and return tool-level errors for invalid inputs so agents self-correct through normal tool calls. Proof ids are validated as single path elements before any filesystem read. The server uses stdio transport for local clients and takes credentials only from the local environment.
