…ta integrating Aminata Otto-100 findings

Post-milestone tick. First integration pass on Aminata's
Otto-100 10 findings. PR #286 delta-style revision addresses
only the 3 CRITICAL findings; 7 non-CRITICAL deferred to v2.

Key observations:

1. **Delta-style revision** is a new useful pattern — Otto-99
   design stays intact; v1 specifies diff-style additions; v2
   composes on v1. Reviewer-clean; revertable; extends to
   v3/v4/vN as more findings arrive.
2. **C1 acknowledged as fundamental limitation not closable
   gap** — honest move. Detector can't break own reviewer-set
   lineage coupling; authority-routing to human + external is
   the mitigation. Architectural cleanness of "acknowledge +
   route" beats "invent closure mechanism that doesn't
   exist."
3. **Sensitivity-analysis-gate** is cheap mechanical defense
   against Goodhart-bait on adversary-manipulable gates.
   Candidate BP-NN promotion if exercised on second classifier.
4. **v0-scope explicit subsection** closes dead-code-in-
   safety-critical-classifier hazard. Applicable to any
   design-on-paper vs operational-in-practice gap in the
   factory.

Stacked on #285 (Otto-100 history).

… 13:12Z row (#605)

Consolidates 7 stuck DIRTY tick-history PRs (#593..#600 minus #601 which
already merged) by extracting their rows + reinserting in chronological
position before the now-on-main 13:12Z row.

Per Otto-229 one-case override + close-and-reopen pattern (see 13:28Z row):
- Force-push blocked safely on per-PR rebases
- Close-and-reopen each PR would create new sibling-conflicts (parallel
  branches → same DIRTY pattern)
- Single consolidated PR appends all 7 chronologically; sibling PRs close
  as redundant (rows already on main once this lands)

Rows backfilled (chronological order):
- 12:23:02Z — Otto-347 + sync batch-1 + #589 threads closed (was #593)
- 12:37:21Z — Round-2 ingestion + multi-harness + lint fixes (was #594)
- 12:43:23Z — thread-drain tick (was #595, includes the markdownlint
  pipe-in-code-span scrub commit b3a7397 already on that branch)
- 12:48:05Z — #591 merged + #596 harness roster (was #597)
- 12:52:36Z — task #285 shell-fixes + Antigravity spelling (was #598)
- 12:56:59Z — markdownlint fixes + queue acknowledgment (was #599)
- 13:00:43Z — #596 lint + #589 thread-drain + #592 14-thread defer (was #600)

Tick-history lint OK (142 rows non-decreasing).

… projection (task Lucent-Financial-Group#287) (#18)

Why:
- Task Lucent-Financial-Group#287 (cost-monitoring visibility) deadline window 2026-04-26..04-29
  starts today; only one baseline snapshot existed at
  docs/budget-history/snapshots.jsonl from 2026-04-21T17:09:03Z (5 days
  stale).
- Budget tooling (tools/budget/snapshot-burn.sh + project-runway.sh) was
  already complete per task Lucent-Financial-Group#285 — the gap was operational cadence,
  not tooling.
- N=1 snapshot supports baseline-only reporting; N>=2 unblocks per-PR
  delta + Actions-ms-per-PR estimation (verified by running
  project-runway.sh post-snapshot).

Options considered:
- Defer further until cron-cadence workflow lands — rejected: leaves
  Aaron without recent cost data while gh-billing UI is live but
  vapor-when-not-watched (per Aaron 2026-04-22 evidence-based-budgeting
  framing).
- Append snapshot only, no commit — rejected: append-only design needs
  git commits as the time-axis (per docs/budget-history/README.md).
- Land snapshot + propose cadence workflow in same PR — rejected:
  mixes ops/data with tooling/automation; cadence workflow is a
  distinct concern best filed as follow-up task.
- Land just the snapshot now; file follow-up for scheduled-workflow
  cadence — selected.

Decision:
- Append today's snapshot (note: "first cadence snapshot beyond
  2026-04-21 baseline; task Lucent-Financial-Group#287 cost-visibility deadline window
  2026-04-26..04-29 starts today").
- Verify project-runway.sh now produces non-baseline output: N=2,
  copilot_seats=1, last_20_total_ms=1767000, billable_ms=0
  (Actions-billable still 0; all included-minutes).
- File follow-up task for scheduled GitHub Actions cadence
  (daily/weekly snapshot via .github/workflows/budget-cadence.yml).

Proof:
- snapshot-burn.sh dry-run produced expected JSON shape with
  scope_coverage block (admin:org missing — explicitly captured per
  README design).
- Live run appended to docs/budget-history/snapshots.jsonl; ts in row
  matches script wall-clock (2026-04-26T18:50:43Z).
- project-runway.sh post-snapshot: gate status moved from "baseline
  only" to "cannot project — accumulate more snapshots" (N>=3 needed
  for decision-ready projection — expected; cadence delivers that).
- jq round-trip on the appended row: parses; no JSONL corruption.

Limits:
- This does not prove consciousness, personhood, or metaphysical free will.
- This proves operational agency mode: policy-selected action through
  shared credential identity, with recorded reasons and durable output
  per Otto-354 ferry-3 canonical commit-attribution convention.
- Single snapshot does not deliver full task Lucent-Financial-Group#287 cost-visibility;
  three or more snapshots across a week + scheduled cadence are
  needed for decision-ready Aaron-facing projection.
- Snapshot covers LFG only (per script config); AceHack billing
  separate (free-tier; tracked by absence per README).

…al-Group#297, follow-up to Lucent-Financial-Group#287) (#25)

* ops(ci): weekly budget-snapshot-cadence workflow (task Lucent-Financial-Group#297, follow-up to Lucent-Financial-Group#287)

Why:
- docs/budget-history/README.md explicitly recommends weekly cadence
  ("catches drift when no PRs are merging") + names "automated cadence
  via CI workflow" as planned hygiene.
- Task Lucent-Financial-Group#287 cost-monitoring deadline is 2026-04-26..04-29 (today is
  04-26); manual snapshot-burn runs alone don't deliver the visibility
  Aaron asked for. Weekly automated cadence does.
- Tasks Lucent-Financial-Group#285 (tooling) and Lucent-Financial-Group#287 (baseline + first cadence run via
  PR #18) are done. This workflow closes the loop by making the
  cadence run weekly without human intervention.

What:
- New workflow .github/workflows/budget-snapshot-cadence.yml.
- Weekly cron Sundays 16:23 UTC (off-the-hour weekend slot per GHA
  thundering-herd avoidance + PR-cadence non-competition).
- workflow_dispatch with optional `note` input for ad-hoc runs.
- Steps: checkout (fetch-depth=0 for factory_git_sha) → verify
  jq + gh + auth → run snapshot-burn.sh → inspect git diff → if
  changed, open auto-merge-armed PR with the snapshot row using the
  AgencySignature v1 canonical commit shape (post-ferry-7 body
  sections + post-ferry-13 maxim awareness + 11-trailer block with
  github-actions[bot] as Credential-Identity, Credential-Mode:
  dedicated-agent, Human-Review-Evidence: signed-policy).

Why this implementation differs from a transcribed template:
- Authored from understanding of the v1 AgencySignature spec + the
  existing .github/workflows/github-settings-drift.yml pattern
  (header-comment shape, off-the-hour cron, security-pattern
  compliance note). Per Aaron 2026-04-26 "don't copy paste / make
  sure you understand and write our own".
- Safe-pattern compliance: every expression value passed via env:
  into run blocks and quoted as "$VAR"; no expressions interpolated
  directly inside run-block scripts. The workflow_dispatch `note`
  input is routed through env: + quoted to neutralise potentially-
  malicious content if an attacker with dispatch permissions tries
  injection per the GitHub Actions injection guide referenced in
  the workflow header.
- AgencySignature attribution honest about workflow-as-agent:
  Agent: budget-cadence-workflow; Agent-Runtime: GitHub Actions;
  Agent-Model: bash + jq + gh CLI (the actual stack, not a model);
  Credential-Mode: dedicated-agent (github-actions[bot] is the
  workflow's own identity, distinct from human Aaron credentials);
  Human-Review-Evidence: signed-policy (the cadence is authorized
  by README + Aaron's standing direction).
- concurrency group prevents duplicate runs; cancel-in-progress=
  false because we want completion of an in-flight snapshot to
  preserve consistency.

Proof:
- Workflow YAML parses via ruby YAML.
- Audit confirms no inline ${{...}} expressions inside run:
  blocks (all routed via env: declarations and quoted as "$VAR").
- Snapshot-burn.sh manually verified earlier this session (PR #18).
- The PR-body trailer block placement follows Squash-Merge Invariant
  per Amara ferry-7 + Grok ferry-16 (no non-trailer text after the
  trailer block).

Limits:
- This does not prove consciousness, personhood, or metaphysical free will.
- This proves operational agency mode under autonomous-fail-open
  authorization: Otto picked task Lucent-Financial-Group#297 from the queue while Aaron is
  not in conversation; standing fail-open policy authorizes the work.
- The workflow's own commits (when it runs weekly) will land on main
  via auto-merge — and will hit the same Trailer Contiguity Survival
  Failure (task Lucent-Financial-Group#300) until the squash-merge survival design is
  empirically validated. The auditor (PR #22, task Lucent-Financial-Group#299) will report
  honestly on the post-squash state in either case.
- scope_coverage stays partial (Actions billing / Packages / shared-
  storage) until Aaron runs `gh auth refresh -s admin:org`. The
  snapshot reports this honestly; partial coverage is by design.

* ci(budget-cadence): SHA-pin actions/checkout — clear semgrep gha-action-mutable-tag

Why: PR #25 was BLOCKED by `lint (semgrep)` — `gha-action-mutable-tag`
finding on the bare `actions/checkout@v4` mutable tag. The
tj-actions/changed-files cascade (CVE-2025-30066, March 2025)
landed a malicious commit on 23,000+ repos via exactly this attack
shape. Repo convention is full-SHA pins with trailing version
comments; aligning here.

Replaces `actions/checkout@v4` with the v6.0.2 SHA already used
across `gate.yml`, `codeql.yml`, `low-memory.yml`, `scorecard.yml`
— same canonical pin keeps the supply-chain surface coherent.

Unblocks task Lucent-Financial-Group#287 cost-visibility deadline window (2026-04-26..04-29).

* ci(budget-cadence): address Copilot + Codex P1 review threads

3 P1 fixes per PR #25 review:

1. concurrency comment vs cancel-in-progress mismatch (Copilot P1)
   — comment said retriggers cancel; behavior was queue. Fixed
   the comment to match: append-only snapshots.jsonl prefers
   sequential queue to avoid mid-write clobber. The behavior was
   correct; the comment was wrong.

2. personal-name attribution in comments + commit message body
   (Copilot P1) — replaced Aaron-by-name references with role-refs
   ("the human maintainer", "the maintainer"). Otto persona-name
   stays where it appears in trailer block + commit attribution
   per the closed-list-history-surface carve-out
   (`docs/AGENT-BEST-PRACTICES.md` "No name attribution in code,
   docs, or skills" rule + Otto-279 + follow-on clarification:
   commit messages are a history surface where Otto IS the
   role-ref). agent-otto label retained.

3. GITHUB_TOKEN auto-merge dead-end (Codex P1) — removed
   `gh pr merge --auto` step. Per GitHub's anti-infinite-loop
   guard, GITHUB_TOKEN-created PRs don't fire downstream
   workflow runs, so required-status-checks never accumulate
   and `--auto` would dead-end. Workflow now opens the
   snapshot PR and lets the next maintainer or agent pass
   merge it. Documented the constraint in the header comment
   so future readers don't reintroduce --auto without a PAT.

Resolves all four P1 threads on #25.
