Its accepted Node target +completed in 540,853 ms and its faithful-local M6 target completed in 545,257 ms, each +below its independent 600,000 ms deadline. + +`pnpm test:m7:local` passed all 23 Node VFS tests. The selected +correctness/fault/resource target completed in 85,549 ms and the complete local gate in +90,271 ms, below the 600,000 ms selection deadline. Coverage included the adversarial +namespace, empty-create, ambiguous-commit, inode-metadata, metrics, multi-edit COW, and +caller-allocation regressions; seven shared file-backed cases; all 36 three-session +commit/close orders; exact 1/16/64-session pressure; 4/8/16 KiB persisted COW formats; +process restart; retryable close; and every observed SQL position in separate +152-position staging and 203-position visible-commit fault phases. + +The 100 MiB fixture retained SHA-256 +`dbd3abb6b32a319a2156c5312956281c6939d950f823eb6f7e039eaf4e9d0435` after 1,000 +deterministic one-byte overwrites. Managed resident memory peaked at 102,983,960 bytes +below the 134,217,728-byte aggregate limit.

It +opened the real writable `/dev/fuse`, selected `/usr/bin/fusermount`, and recorded four +kernel mount cycles across four distinct provider PIDs and exactly three restarts. + +The exact operation-count profile wrote and recovered a deterministic 16 MiB fixture, +observed 5,000 control-delimited mounted one-byte callbacks, performed 2,000 namespace +operations, ran 16 readers and 16 writers for 64 operations each, and completed 9,056 +counted operations. Its edit window used one successful optimized COW flush with no +failed flush, while total source work remained below the fixture plus the profile's +524,288-byte workload ceiling. The final payload digest was +`3238fa53923434d162289488f802739eecc4a45303799b7ca4c4b38fddba5d1a`. + +The smoke separately proved fsync across abrupt provider death, close durability, +interrupted/resumed collection, a fresh completed final collection, full integrity and +usage verification, zero active leases/staging/reservations, and final unmount. It +completed in 24,767 ms and the gate in 24,815 ms, below 60 seconds. Managed resident +memory peaked at 59,762,873 bytes below the 134,217,728-byte aggregate limit. + +The candidate deliberately retains `validate:accepted` on M6 while these gates run.

Keep +`validate:accepted` pointing at M7 until every M8 gate passes. Do not reset, +rebase, discard, or overwrite the approved M8 planning documentation. Do not +create an M8 evidence or acceptance commit while any gate is missing or +blocked. + +The implementation must preserve all accepted M0-M7 behavior, limits, +authentication, restart semantics, branch isolation, fault positions, and +evidence requirements. + +## 2. Hard blockers to resolve first + +The following are acceptance blockers, not optional test additions. + +### 2.1 Core-owned bounded export capture + +Implement a durable, core-owned export snapshot operation: + +- Create and maintain an outbound export lease for the selected main revision + or branch generation, including owner nonce, expiry, protected roots, and + cleanup state. +- Capture branch rows through durable keyset pages, not `OFFSET` scans or one + capture transaction. Persist the page cursor and snapshot summary after each + accepted page. +- Keep branch capture bounded for the configured 100,000-row branch limit. +- Preserve the exact generation, predecessor generation/digest, base revision, + namespace overlay, inode state, COW pages, patches, expectations, links, + symlinks, and immutable references. +- Renew only live leases; an expired lease must never be revived. +- Expiry, abort, retry exhaustion, compaction, and garbage collection must + release every root, buffer, reservation, and lease. + +The API must remain schema-free and core-owned. Do not expose SQL, tables, +repositories, raw manifests, CAS insertion, or COW mutation to the replication +package. + +### 2.2 Bounded destination activation + +Replace full-generation activation with a bounded activation protocol: + +- Stage immutable content and branch rows in bounded durable batches. +- Maintain a durable staged-generation summary/digest while accepting pages. +- Activate by a constant-row pointer/generation swap guarded by exact base, + generation, predecessor digest, and generation digest. +- Move materialization, old-row cleanup, and staged-row deletion to bounded + maintenance after the pointer swap. +- Do not call a full staged-row materializer or rescan the complete branch + generation during final activation. +- Enforce configured limits above 65,536 rows; the accepted maximum is 100,000 + changed paths. + +The resulting visible generation must be atomic and reconnectable after every +durable statement fault. + +### 2.3 Main incremental and genesis continuation + +Implement durable continuation for every bounded state category: + +- Namespace inode rows, entry rows, manifest roots, revision fragments, and + checkpoint rows need explicit cursors and fragment completion state. +- Never advance a revision cursor after only a bounded prefix was emitted. +- Genesis bootstrap must continue beyond the first 256 rows. +- Main catch-up must use the destination’s actual durable head, not a constant + zero, and must transfer only missing revisions/content. +- Add tests with rows above negotiated batch limits and with a destination + already at revision N. + +### 2.4 Durable replay and terminal authorization + +Complete the protocol’s durable retry semantics: + +- Persist missing-content response bytes or an equivalent durable replay receipt + before advancing the outbound sequence. +- Drop and replay requests and responses independently in every phase, + including missing-content, activation, result acknowledgement, and restart. +- Reject renewal after expiry with the canonical semantic error. +- Only an authority source may originate merged/discarded terminal state or a + publication result. Validate flow and source role inside the destination + activation command. +- Repeated terminal delivery with identical branch identity, generation, + digest, terminal state, and retained result must replay idempotently. Any + mismatch must leave the destination unchanged. +- Keep operation IDs bound to the complete guarded request. + +### 2.5 Generation/publication correctness + +Retain and extend the existing generation guard behavior: + +- Compare expected generation and expected generation digest inside the + authoritative publication transaction. +- Verify repeated authority-branch delivery after the source branch advances; + the exact predecessor digest must be carried and checked. +- Verify lost publication responses replay exactly one stored result and create + no second revision. +- Verify terminal publication/discard state and retained result return to the + execution replica, followed by stale-branch reconnect rejection with no main + fallback. + +## 3. Computer closeout + +Computer must remain a thin carrier/lifecycle adapter. Any additional +filesystem or replication state machine belongs in the host-neutral FS runtime. +The documented Computer production budget is approximately 100 net-new lines; +if the integration requires materially more, stop and move the abstraction to +the FS worktree before continuing. + +### 3.1 Production transport + +Use the actual Cap’n Web carrier: + +- Authenticate and bind the peer before the first replication exchange. +- Keep replication on a separate uncompressed `/efs` connection or make the + replication connection uncompressed; preserve legacy `/ws` behavior. +- Enforce raw frame ceiling `4 MiB + 64 KiB`, decoded request/response ceiling + `3 MiB`, mutating acknowledgement ceiling `64 KiB`, scratch ceiling `2 MiB`, + one exchange per operation, and one process-wide 20 MiB admission pool. +- Permit at most one 17.25 MiB exchange, with smaller reservations coexisting + only when the aggregate fits. +- Account raw frame, decoded string, base64 expansion, decoded envelope, + acknowledgement, scratch, transient RPC copies, stubs, and process buffers. +- Use `session.ping` for liveness; never use an empty replication transaction. +- Disconnect cleanup must release stubs and process reservations while keeping + durable resumable filesystem state. + +### 3.2 Lifecycle and mounts + +Prove all lifecycle states with a real persistent database: + +- Fresh empty replica: only unbound provisioning is exposed; no FS or Node VFS + view exists before binding. +- Restart after every accepted provisioning batch and around final activation. +- Bind the exact authority identity, root, revision-zero metadata, timestamps, + conflict tokens, page size, writer profile, manifest format, and FastCDC + configuration. +- Transfer main, mount the exact active branch ID, reconnect after restart, + and preserve branch isolation. +- Exercise shell/Git operations, hard links, symbolic links, rename, chmod, + truncate, range writes, fsync, unmount, remount, and digest verification. +- Return the active branch to the authority through the actual Cap’n Web + carrier, publish exactly once with generation-and-digest guards, replay a + lost publication response, and return the terminal result. +- Delete/replace the local database, reprovision and retransmit main plus the + active branch, remount the same branch, and verify exact identity/digest. +- Verify pinned readers survive activation, dirty writers receive the stable + documented busy/divergence error, caches invalidate, and no dirty state is + silently rebased or discarded. +- Bind each mount to workspace, engine, and branch. Enforce read-only policy + locally. External mounts are not replication peers and must not receive + private branch writes before explicit publication policy permits them. + +The normal production path must not silently remain a DOFS-only workspace path +when the EFS carrier/profile is selected. If `/ws` remains legacy DOFS, the +EFS lifecycle must be explicitly and completely wired through the documented +Computer ownership boundary. + +## 4. Required test and fault matrix + +Add or extend shared tests for: + +- All canonical golden vectors and corrupt/noncanonical inputs. +- Every legal/illegal role-flow pair and changed authorization/policy/limits. +- Fresh provisioning, every-batch restart, binding identity, wrong database, + wrong schema/engine/workspace/authority, and database replacement. +- Empty, deduplicated, multi-batch, checkpoint, main, and every active-branch + transfer flow. +- 100 MiB one-byte edit: only changed roots/nodes/objects, bounded metadata, + and overhead transfer; no complete-file replication memory. +- Request loss, response loss, duplication, reordering, and process restart in + every phase, including missing-content and activation responses. +- Fault injection after every durable statement and activation boundary. +- Branch base visibility, private isolation, read-only main, no fallback, + reconnect, terminal closure, and exact generation digest. +- Guarded publication, intervening mutation, conflict, lost response, terminal + return, and stale reconnect rejection. +- Lease expiry, non-revival, receipt compaction, abandoned staging, retry + exhaustion, cleanup, garbage collection, and zero residue. +- 64 streams, 64 Node VFS writers, replication, queries, and GC under the one + aggregate managed-memory ceiling. +- The unchanged CT-SCALE-1 100,000-row Node-to-Node and + Node-to-Durable-Object fixtures. + +The affected runner must retain live output, must map every new package/source +area in `scripts/run-affected-tests.mjs`, and must conservatively select the +quick suite for unknown changes. + +## 5. Mandatory Computer gate + +Run the exact clean pair of candidate commits through all 17 required steps in +the controlling M8 plan, using: + +- actual Cap’n Web over WebSocket; +- authenticated peer binding; +- real privileged Linux FUSE kernel mount; +- persistent SQLite files and real process restarts; +- no mock, shim, binary loopback, or Node-VFS-only substitute. + +The gate must record pass/fail for every numbered step, every dropped request +and response position, every restart position, and every cleanup assertion. + +If privileged FUSE, the actual carrier, or another required external capability +is unavailable, preserve the exact diagnostic and mark M8 blocked. Do not +weaken the gate or substitute a mock. + +## 6. Evidence and commit order + +For a passing run only: + +1. Start from clean FS and Computer candidate commits. +2. Run all mandatory gates and collect commands, versions, carrier settings, + capabilities, limits, seeds, fixtures, identities, digests, flow counts, + fault points, restart counts, timings, memory peaks, WAL/database growth, + transferred/reused bytes, lease/reservation state, cleanup, and log hashes. +3. Extend evidence verification to reject candidate drift, wrong topology, + fabricated logs, wrong commands/workloads, wrong carrier settings, missing + FUSE identity, resource violations, and incomplete cleanup. +4. Commit the evidence atomically as the direct child of the production + candidate. +5. Create a narrowly scoped acceptance commit only after evidence verification + passes. +6. Only then update the milestone acceptance pointer; retain M7 acceptance + until that point. + +Never push, deploy, publish packages, change production Cloudflare state, or +delete user data without explicit authorization. + +## 7. Definition of done + +Handoff is complete only when all of the following are true: + +- Every blocker in section 2 is fixed in the core-owned runtime and covered by + a regression test. +- Computer is a thin, authenticated, bounded carrier/lifecycle adapter within + the documented production budget. +- The exact mandatory Computer/FUSE gate passes on the exact clean pair. +- All required FS, Computer, fault, performance, cleanup, and evidence checks + pass without weakened workloads or limits. +- Candidate, evidence, and acceptance commits have the required topology. +- `validate:accepted` is advanced only after M8 acceptance. +- The original dirty repository remains byte-for-byte untouched by this work.
