docs/PHASE7: review fold-in — 3 BLOCKERs + 6 CONCERNs + 5 NITs

Browse Source 
Sonnet-reviewed (per the reviews-use-sonnet feedback memory).

BLOCKERs (RESOLVED in-place):

R1. M.chat would silently return (text, nil) for ALL non-streaming
    callers — 4 of 5 categories (summarize/delegate/memory_summarize/
    probe) flow through broker.chat, NOT chat_stream. §4 now shows
    the explicit M.chat update that captures kind=="usage" alongside
    "text" and returns (text, usage).

R2. call_broker fallback retry would credit usage to the wrong model
    name. Fix: broker emits payload.model = model_cfg.model (which IS
    the fallback's name when called with fb_cfg — chat_stream's
    upvar). Wrapper keys by payload.model, NOT outer model_name. §4
    + §13 commit 3 reflect.

R3. build_request has TWO internal callers inside broker.lua itself,
    not just the public surface. Plan §13 commit 1 risk row now
    spells this out explicitly so the implementer doesn't read "every
    caller already passes opts" as "external-only".

CONCERNs (FOLDED):

R4. Single cost_warn_fired flag covers two thresholds — first-to-fire
    suppresses the other. Split into ctx.cost_warn_state = { dollars
    = false, tokens = false }; :cost reset clears both. §7 + §13.

R5. Warn-check centralization — single _record_usage helper in
    repl.lua wraps ctx:add_usage AND does threshold check. safety.lua
    routes via helpers.on_usage / opts.on_usage callbacks. context.lua
    stays decoupled from renderer.

R6. Preserve nil-vs-0 cost distinction. Accumulator slot gains
    `is_local = true` (sticky) when ANY recorded usage had cost==nil.
    `:cost detail` annotation comes from is_local flag, not a
    fragile cost==0 heuristic.

R7. :cost detail sort needs 3-level deterministic key:
    (cost desc, model asc, category asc) — table.sort is unstable.

R8. call_broker fallback passes opts.include_usage unchanged.
    Documented as known assumption (B1 confirms both backends
    accept; future-broken fallback can pass include_usage=false).

R9. :resume does NOT restore historical usage_totals. Per-turn usage
    IS in session JSONL for scripting; cross-session aggregation is
    Q-C2 deferred. Documented in §8.

R10. $%.4f loses sub-cent precision (cloud cost 0.000028 -> $0.0000).
     Widened to $%.6f in §6 + §7 warn message format.

NITs (APPLIED):

N1. §4 pseudocode comment notes `if doc.usage` branch is independent
    of choice branch (handles both B2 emission shapes).
N2. §2 stale "B7" reference corrected to B3.
N3. §13 commit 3 row gains explicit dependency note on commit 1's R1.
N4. §13 commit 4 spells out llm_probe -> llm_second_opinion ->
    M.is_destructive signature chain widening.
N5. §3 + §13 commit 6 — PHASE0 §11 amendment already in tree
    (3bad07b); commit 6 must NOT re-apply.

PHASE7.md now 803 lines (was 528 after plan). +275/-57. Ready for
implementation phase pending user gate.

**Project:** aish — AI-augmented conversational shell
**Document:** Phase 7 Requirements, Architecture & Design Decisions
**Status:** Plan (formulate + analyze + baseline complete; tree at `2244a3f`)
**Status:** Plan + review fold-in (tree at `0f14dc1`)
**Date:** 2026-05-16
**Review findings (independent Sonnet agent, 2026-05-16) — 3 BLOCKERs
resolved in-place, 6 CONCERNs folded, 5 NITs applied:**
R1 (BLOCKER, RESOLVED). **`M.chat` would silently return `(text, nil)`
for ALL non-streaming callers.** `M.chat`'s internal on_delta only
captures `kind == "text"`. Without explicit handling of
`kind == "usage"`, four out of five categories that go through
`broker.chat` (summarize / delegate / memory_summarize / probe)
would report zero usage even after a cloud round-trip. **Fix
folded into §4 + §13 commit 1:** M.chat's on_delta also captures
the usage payload and returns it as the second value.
R2 (BLOCKER, RESOLVED). **`call_broker` fallback retry — usage
payload's `model` field credits the WRONG model name.** The
`wrapped` on_delta in call_broker is closed over the PRIMARY's
name; if the wrapped function uses an outer-scope `model_name`
variable to key the accumulator, the fallback's usage gets
misattributed. **Resolution:** the broker emits `payload.model =
model_cfg.model` (which IS the fallback's model when called with
`fb_cfg` — chat_stream's local upvar). The wrapper keys by
`payload.model`, NOT by the outer `model_name`. Documented in
§4 emission code + §13 commit 3 (wrapped on_delta uses
`payload.model` for accumulator keying).
R3 (BLOCKER, RESOLVED — promoted to docs). **`build_request` has
TWO internal callers inside broker.lua itself**, not just the
public surface. Migration is contained but both internal sites
must be updated in commit 1. Plan §13 commit 1 risk row updated
to call this out explicitly so the implementer doesn't read
"every caller already passes opts" as "only external callers
need touching".
R4 (CONCERN, FOLDED). **Single `cost_warn_fired` flag for two
thresholds is broken.** When both warn_at_dollars AND
warn_at_tokens are configured, the first-to-fire suppresses the
other. **Fix:** `ctx.cost_warn_fired` becomes `ctx.cost_warn_state
= { dollars = false, tokens = false }`. Each threshold has its
own flag; `:cost reset` clears both. §7 pseudocode updated.
R5 (CONCERN, FOLDED). **Warn-check centralization decided:** use a
single `_record_usage(model, category, usage)` helper inside
repl.lua that wraps `ctx:add_usage` AND does the threshold check
AND calls renderer.status when crossed. `context.lua` stays
decoupled from `renderer`. safety.lua call sites get
`helpers.on_usage = _record_usage` in the helpers table; probe
callsite gets `opts.on_usage = _record_usage`. Single chokepoint
for the warn check. §3 + §7 + §13 commits 3-5 reflect.
R6 (CONCERN, FOLDED). **`nil` vs `0` cost distinction must be
preserved at the accumulator level.** Local-model `$0` (no cost
field) vs cloud-call-that-happens-to-cost-zero need to be
distinguishable for `:cost detail` annotation. **Fix:** accumulator
slot gains `is_local = true` when ANY recorded usage for that
slot had `cost == nil`. Cloud calls with `cost = 0` (rare) stay
annotated as cloud. §5 pseudocode + §6 annotation logic updated.
R7 (CONCERN, FOLDED). **`:cost detail` sort needs three-level key
for determinism.** Lua's `table.sort` is unstable; equal-cost
rows would have arbitrary order. **Fix:** sort key is
`(cost desc, model asc, category asc)`. §6 updated.
R8 (CONCERN, FOLDED). **`call_broker` fallback passes `opts.include_usage`
unchanged.** Documented as a known assumption (B1 confirms both
backends accept; if a future fallback host rejects, the call-site
can pass `include_usage = false` explicitly). §10 risk row added.
R9 (CONCERN, FOLDED). **`:resume` does NOT restore historical
`usage_totals`.** Per-turn usage IS in the session JSONL but
`:resume` reloads turns for conversation continuity only; the
accumulator stays empty. Documented in §8 surface notes; users
who want cross-session totals can script the jsonl or wait for
the deferred Q-C2 follow-up.
R10 (CONCERN, FOLDED). **`$%.4f` loses sub-cent precision.** A
`0.000028` cloud cost displays as `$0.0000` — indistinguishable
from `$0` local. **Fix:** format strings widened to `$%.6f` in
§6 (and the warn message in §7). 6 decimal places accommodates
the smallest observed real cost.
R-N1..N5 (NITs, APPLIED):
N1. §4 extraction pseudocode gains a comment noting the
`if doc.usage` branch is INDEPENDENT of the choice branch and
must be checked regardless of choice nil-ness (handles both
B2 emission shapes).
N2. §2 "Cost extraction" row referenced stale "B7"; corrected to B3.
N3. §13 commit 3 row gains an explicit dependency note: commit 3's
"capture the new second return value" requires commit 1's M.chat
fix from R1 to ship first.
N4. §3 safety.lua row + §13 commit 4 row spell out the signature
chain: `llm_probe` → `llm_second_opinion` → `M.is_destructive`
all widen to thread `opts.on_usage` through.
N5. §3 PHASE0.md row + §13 commit 6 row — the PHASE0 §11 amendment
is ALREADY in tree (committed at `3bad07b` with the formulate
doc). Commit 6 should NOT re-apply; only adds config.lua block

only captured text. Under Phase 7 it MUST also capture the usage
payload — otherwise EVERY non-streaming caller (summarize, delegate,
memory_summarize, probe — 4 of 5 categories) silently reports zero.

local ok, err = M.chat_stream(model_cfg, messages,
function(kind, payload)

end, opts)

| Commit | Risk | Mitigation |
|---|---|---|
| 1 (broker) | build_request signature change breaks all existing callers | All callers of chat_stream/chat use opts already; we move tools/max_tokens INTO opts — temporary positional fallback (`opts.tools = old_tools` if positional was used) is unnecessary because every caller already passes opts table |
| 1 (broker) | R3: build_request has TWO INTERNAL callers in broker.lua; both must be updated in this commit | Explicit in commit-1 note above; grep `build_request\(` to confirm |
| 1 (broker) | R1: M.chat must capture usage in on_delta and return (text, usage) | §4 shows the explicit M.chat update; smoke test verifies non-nil usage on cloud call |
| 1 (broker) | `M.chat` second return value confuses callers that do `local r = broker.chat(...)` discarding the second | Lua doesn't error on dropped return values; backward-compat preserved automatically |
| 2 (context) | usage_totals nil on old ctx serializations | Defensive `self.usage_totals = self.usage_totals or {}` in add_usage; no migration needed |
| 3 (repl wires) | Forgetting one call site = silent under-count | Lint by grep for `broker.chat\(` and `broker.chat_stream\(` after the wire commit; ensure each is tagged |
| 4 (safety wires) | safety.lua must NOT require("secrets")-style introduce new module dep | Use helpers.on_usage callback convention (same shape as #52's scrub_msgs) — no module dep |
| 5 (:cost + warn) | warn fires multiple times when threshold is much exceeded by one call | cost_warn_fired one-shot flag; explicit :cost reset to re-arm |

| 3 (repl wires) | R2: fallback retry credits usage to wrong model | wrapped on_delta keys by `payload.model` (set inside broker per R2), NOT by outer `model_name`; smoke a deliberately-broken-primary case |
