Restate the PROBLEM in plain English + +Simard has a goal to shrink the CVE knowledge pack by storing its embeddings in a +compact 8-bit form (int8/PQ) instead of full 32-bit floats. That work was only +allowed to "ship as done" once a separate accuracy check proved the compact form +still finds the right answers just as well as the original (a recall-parity check). +The yardstick that check needs came from a *different* piece of work — the +full-pack evaluation baseline. + +When the goal was first flagged stuck, that yardstick had not yet been built, so +Simard literally could not measure whether the goal was finished — it could neither +declare success nor failure, so every cycle it re-opened the goal and +re-investigated without shipping anything. That is a treadmill, not a failure; a +worker relaunched and returned with nothing unblocked because the thing it waited on +lived outside its own work. + +## 2. Recommended NEXT STEP (plain English) + +Mark this goal finished and retire it. The compact-embedding work has already +shipped, and the accuracy yardstick it was waiting on has since been built and +landed too — so nothing is left to do and nothing is left to wait on. Retiring it +durably stops the every-cycle re-open treadmill. + +## 3. ROOT CAUSE and course-correction DECISION + +### 3a. Root cause (grounded in live evidence) + +The goal was flagged blocked for a real reason: its finish line depended on an +**upstream deliverable owned by a different issue (#16)** — the recall-parity +evaluation baseline — and at the moment it was flagged, that baseline had not yet +landed, making the done-check **unmeasurable**. Two layers: + +1. *Historical/true block:* an upstream-dependency done-gate (recall parity vs. the + #16 baseline) that was unmeasurable while #16's baseline was unlanded. +2. *Why it is still on the board now:* both the dependency and the work have since + landed, but nothing ever recorded this goal as complete — so the daemon keeps + re-picking it up each cycle. + +### 3b.

Why the parity criterion was never directly observable (done-gate code grounding) + +`src/goal_curation/completion_gate.rs::EvidenceSource` defines the *complete* set of +machine-observable signals the done-gate can check: PR MERGED (`any_pr_merged`), +issue CLOSED (`issue_closed`), self-change deployed (`is_deployed`), governed repo +present (`repo_present`), and upstream `dependency_goal_state` → +`DependencyState::{None,Pending,Resolved}`. `evaluate` is a strict AND-gate +(`Complete` iff `pr_merged && issue_closed && (!self_affecting || deployed)`; any +missing clause → `Blocked`; any source error → `Blocked{CouldNotVerify}` — it never +completes on unverifiable evidence). + +Crucially there is **no eval/metric signal** in `EvidenceSource`. "int8/PQ recall +parity vs. the #16 baseline" is prose the gate can never certify *directly*; the only +way to make it machine-checkable is to bind it to an observable anchor +(`done_gate_pins.rs::DoneGatePin` — a MERGED PR / CLOSED issue / committed artifact / +command output). `DependencyState` models the #16 relationship exactly: `Pending` +→ Paused; `Resolved` → auto-clears. **Live state = `Resolved`** (#16 CLOSED, PR #41 +MERGED). And #17's own delivery is now certifiable via the standard gate: +`any_pr_merged`=true (PR #40) and `issue_closed`=true (#17) are both satisfied. + +### 3d. Decision (exactly one, per procedure §"HOW TO DECIDE") + +**`complete-delivered-goal`.** + +The work this goal describes already shipped via **merged PR #40 (`Closes #17`)**, +and the recall-parity dependency it was gated on already shipped via **merged PR #41 +(`#16` CLOSED)**. The rule "Complete a goal already delivered by a merged PR" applies +directly, and completion writes a **durable tombstone** that no path (seeding, memory +recall, meeting handoff, cycle reconcile) can resurrect — stopping the relaunch for +good. + +**Why not the other two options:** + +- *rewrite-done-gate* — would be correct **if #16 were still open**: re-point the + gate at a machine-observable condition (e.g. "#16 observed CLOSED **and** PR #41 + observed MERGED **and** committed parity artifact + `data/packs/cve/eval-results.json` shows `delta_accuracy >= -0.02`"). But #16 is + CLOSED and PRs #41/#40 are MERGED, so the gate condition is already satisfied — + there is no unmeasurable gate left to rewrite; the goal is simply done. +- *ask-operator-one-question* — not warranted: no scope call or ambiguous intent is + the operator's to make; the evidence resolves the block deterministically. + +### 3e. Action taken (executed, not proposed) + +Retired the goal through the shipped operator CLI (`src/operator_cli/goal.rs` +`handle_complete` → `tombstone`), which removes it from the board and writes the +durable tombstone (idempotent on an absent/already-tombstoned goal): + +``` +$ simard goal complete fix-agent-kgpacks-rs-issue-17-ws2-int8-pq-embed-7f5afcca +[simard] goal complete: 'fix-agent-kgpacks-rs-issue-17-ws2-int8-pq-embed-7f5afcca' + not on board; recorded tombstone (idempotent) +``` + +The goal was already off the active/backlog board, so completion recorded the +durable tombstone idempotently — nothing will re-seed or relaunch it next cycle. + +## 4.

PROBLEM — plain English + +Simard could not install her own updates. For several hours every automatic +self-update failed, leaving her running an older build that had drifted about six +approved changes behind the latest code, slipping one further behind each cycle. + +## 3. ROOT CAUSE (grounded in re-verified live evidence) + +A **self-deploy chicken-and-egg deadlock**: + +1. Simard's self-update workspace `~/.simard/self-deploy-src` had one tracked file + with an uncommitted local edit — `.github/hooks/amplihack-hooks.json`, rewritten + by the amplihack install step from relative hook paths to absolute ones. + Verified live: `git -C ~/.simard/self-deploy-src status` showed + `M .github/hooks/amplihack-hooks.json` (workspace `HEAD detached at a350b24d`). +2. The update switches the workspace to the target commit with a plain detached + checkout, which **aborts** when a tracked file has local edits. So the update + failed every tick — verified in `~/.simard/ooda.log`: `deploys=0` and a + persistent `errors=1` on every recent overseer tick; the same dirty file recurs + across `~/.simard/cycle_reports/cycle_*.json`. +3. The **permanent fix is already merged** — PR #4898 (rolls up #4878), + commit `76512653b` "fix(self-deploy): fail-closed canonical-path gate for source + tree reset" — which hard-resets the source tree before checkout so a stray edit + can never wedge the update again. Verified present in this deploy repo's history. +4. But the **running binary is `0.40.0`** (`~/.simard/bin/simard --version`), built + before that fix, so it cannot self-heal the wedge. The fix can only take effect + *after* one successful deploy installs the newer binary — which the wedge itself + was preventing. Hence the deadlock. + +## 4. DECISION — course-correction chosen + +**complete-delivered-goal** — the remedy this block needs has already shipped in a +merged PR (`76512653b` / #4898 / #4878). Per the playbook, the correct move is to +apply the delivered fix rather than leave the system blocked or escalate. + +Two determinations that shaped the exact action (and corrected the prior round): + +- **The goal is a STANDING goal.** Its description ends "Standing goal.", so + `description_marks_standing` → `ActiveGoal::is_perpetual()` is **true** + (`src/goal_curation/types.rs`; pinned by the unit test asserting + `description_marks_standing("Standing goal")`). Consequences: + - The Overseer gap-scan **exempts** standing goals — it "would otherwise oscillate + uncovered every cycle" (`src/overseer/sensor.rs::detect_workstream_gaps`). + Confirmed live: `workstream_gaps_detected=0` on every recent tick, and the goal's + `no_progress` count is **0**. Its idle cycles are benign **by design** + (`src/ooda_loop/no_progress.rs`: "Non-research standing goal (e.g. CI-stewardship). + Idling is NORMAL"). + - `simard goal complete ` on a standing goal **reopens** it + (`roll_to_new_cycle`) rather than removing/tombstoning it. So the prior round's + plan to "complete + tombstone" this goal would NOT have closed anything and is + semantically wrong — an ongoing CI-stewardship duty must remain active. +- Therefore "complete-delivered-goal" was applied to the **blocker's delivered + remedy**, not by terminating the standing goal: I applied the one-time prerequisite + the merged fix needs (unwedge the tree) so the next deploy installs it. The + standing goal is left **active** (correct) and returns to healthy operation once + the update lands. + +`rewrite-done-gate` was rejected: a standing goal has no terminal done-gate to make +machine-checkable, and idling is its normal state. `ask-operator-one-question` was +rejected: no human decision is required — the unwedge is a mechanical action the +agent can perform, and the playbook mandates fixing the block yourself before +escalating. + +## 5. ACTION TAKEN (applied, not proposed) + +On the daemon host, cleared the leftover edit so the update can proceed: + +``` +git -C ~/.simard/self-deploy-src reset --hard # HEAD is now at a350b24d +git -C ~/.simard/self-deploy-src clean -fd # (no untracked files to remove) +``` + +Verified afterward: `git -C ~/.simard/self-deploy-src status --short` is **empty** +(clean), and `git -C ~/.simard/self-deploy-src checkout --detach HEAD` now returns +**rc=0** — the operation that had been aborting now succeeds. No deploy was in +progress during the reset (no deploy lock/process held the workspace), so this was +safe against the live loop.
