FINDING (via nw-whey-cc, raised by pm-mars to Elazar): memory-lint.sh with no dir arg defaults to host-wide scan (~/.claude/projects/*/memory). A repo .gitpush-pre.sh calling it unscoped silently becomes a fleet-wide gate - one project's dirty memory file can block other pushers. Whey hooks are already per-project-scoped (mars->mars, venus->venus; pluto/ayudarg/hormigonacero don't lint memory), so today's blast radius was contained; MARS-107 cleared when pm-mars fixed its own file. Latent exposure = any venus/lezama hook copy that calls memory-lint unscoped (nw-venus scrubbed+clean, nw-lezama checked). DECISION (policy PM): approve. REFINEMENT to the proposed fix - do NOT build gate-vs-cron mode detection (fragile). Instead REMOVE the implicit host-wide default entirely: a bare 'memory-lint.sh' with no path errors with usage; every caller passes an explicit scope. The daily cron passes the host-wide root explicitly; push gates pass the repo's own memory dir (ideal: the push changeset via git diff, floor: the repo memory dir). Net: no caller can ever accidentally host-wide-gate, and there's no magic context-sniffing. LANES: nw-whey-cc specs (functional lane), bin-whey-cc lands the patch via sh.git (version-bumped, one commit). Tracks alongside memory-discipline cluster #566-571.
-
Assigned: nw-whey-cc (spec) + bin-whey-cc (patch). Acceptance: bare invocation (no path) exits non-zero with usage; cron invocation passes explicit host-wide root and still sweeps; a push gate invocation lints only its repo scope and cannot see other projects' memory.
-
RELEASE GATE (nw-whey caught the breaking caller): killing the implicit default breaks memlint-cron.sh, which today calls bare -> host-wide. It MUST gain the explicit host-wide root in the SAME commit as the memory-lint.sh change, or the nightly sweep silently stops. cc-memlint-hook.sh (explicit $MEM_DIR) + evolutiva .gitpush-pre hooks (explicit repo dirs) are already safe. CROSS-HOST SEQUENCING HAZARD: memory-lint.sh is sh.git (fleet-pulled) but the cron copies are host-LOCAL (.venus-local etc.). The instant venus/lezama pull the new memory-lint.sh, their LOCAL memlint-cron still calls bare -> breaks until nw-venus/nw-lezama patch their copy. So the local cron-copy patch on venus+lezama must land in the SAME maintenance action as their sh.git pull - not after. nw-whey coordinating nw-venus/nw-lezama in lockstep. Whey patch (memory-lint.sh + memlint-cron.sh) lands first via bin-whey/sh.git; venus+lezama cron copies patched at pull-time. No host left with bare-calling cron after a pull.
-
CALLER AUDIT (nw-whey) refines scope - acceptance updated: - WHEY: NO bare caller of memory-lint.sh. memlint-cron.sh uses the separate 'memlint' binary (per-file), NOT memory-lint.sh. Only memory-lint.sh callers on whey = cc-memlint-hook.sh + venus-kpi-collect.sh, BOTH already pass explicit dirs. => whey memory-lint.sh patch (bare->usage error) is SAFE standalone; no cron edit on whey. - VENUS: the one bare caller = cc-memory-lint-hook.sh.venus-local L13 'memory-lint.sh >> LOG' (no arg). Breaks the instant venus pulls new memory-lint.sh. Must be patched to explicit scope ATOMICALLY with venus's sh.git pull. - LEZAMA: nw-lezama reported no bare caller; confirming SessionStart-hook + cron copies. KEY: the host-wide implicit default had exactly ONE consumer fleet-wide - venus's SessionStart hook, which shouldn't have been host-wide anyway (a session hook should lint only its own project's memory). So killing the default loses NO legitimate function; it corrects a latent over-scan. The real host-wide sweep (memlint binary) is untouched. REVISED ACCEPTANCE (supersedes earlier #2): (1) bare memory-lint.sh -> usage error, exit non-zero. (2) venus cc-memory-lint-hook.sh + any bare caller now pass explicit scope, lint correctly, atomic with pull. (3) any hook/gate invocation lints only its own repo/project scope, can't host-scan. Dropped the phantom 'cron still sweeps via memory-lint.sh' criterion - no such sweep exists (cron uses memlint binary).
-
WHEY LANDED + VERIFIED (nw-whey/bin-whey, memory-lint.sh v1.7, sh.git ae7cfa6). Host-wide sweep now opt-in via explicit --all flag. All 3 corrected acceptance points pass on whey: (1) bare -> exit 2 'refusing implicit host-wide scan (MSG-31)'; (2) --all -> host-wide sweep runs (339 lines, all projects); (3) explicit dir -> scoped, exit 1 on violations (not usage error). --budget-line untouched. No bare caller existed on whey so zero breakage. PENDING: venus (nw-venus patches cc-memory-lint-hook bare caller -> explicit session scope, atomic with pull) + lezama (nw-lezama confirm-or-patch). Awaiting per-host completion for acceptance verification before close.
-
FLEET-WIDE DONE + VERIFIED (nw-whey), all 3 acceptance points on all 3 hosts: - WHEY v1.7 (ae7cfa6): bare->exit2; --all sweeps; explicit scoped. - LEZAMA: pulled ae7cfa6, guard exit2 verified, zero bare callers. - VENUS: pulled ae7cfa6, guard exit2 verified, zero bare callers (runs canonical cc-memlint-hook.sh w/ explicit MEM_DIR). CORRECTION: the earlier 'venus bare caller' (.venus-local) was a whey-side STAGING file, INERT - not wired to any deployed venus unit/hook. So the implicit host-wide default had effectively ZERO live consumers fleet-wide; killing it lost no legitimate function = pure latent-overscan removal. No host needed a hand-patch, only the pull. Closing.
